The new issue of the New Yorker include a good article about Ecovative by Ian Frazier. Here's a clip:
Gavin McIntyre, the co-inventor of a process that grows all-natural substitutes for plastic from the tissue of mushrooms, holds a pen or pencil in an unusual way. Gripping it between two fingers of his right hand, he moves his arm across the paper so that his wrist grazes the inscribed line; because of this, he uses pens with ink that doesn't smear. When he draws an explanatory diagram of the chitin molecule--chitin is the principal component of mycelium, the white, rootlike vegetative structure of fungi--he bends over his work, then looks up earnestly to see if his hearer has understood. The gesture makes him appear younger than his age, which is twenty-eight. He wears glasses and has straight black hair, dark eyes, and several piercings, with studs in his lip and ears.
The other co-inventor, Eben Bayer, won't be twenty-eight until June. Bayer is almost six-five, and often assumes the benign expression of a large and friendly older brother. His hair is brown, short, and spiky, his face is long, and his self-effacing manner hides the grand ambitions that people who come from small towns (Bayer grew up in South Royalton, in central Vermont) sometimes have. When he says, of the company that he and McIntyre founded, "We want to be the Dow or DuPont of this century," he is serious. He is their company's C.E.O., McIntyre its Chief Scientist. People with money and influence have bet that they will succeed.
As you know, Ecovative is based in Green Island -- and both McIntyre and Bayer are RPI alumni.
The article highlight both of the founders' backgrounds, along with the key role of RPI professor Burt Swersey in encouraging them, and mycologist Sue Van Hook in helping to grow Ecovative's library of fungus. And it also includes a bunch of interesting bits about the company's beginnings, tech, and plans (fungal resistors for mobile phones?).
More than anything, though, Frazier elegantly lays out Ecovative's ideas alongside the history of Dow Chemical -- the producer of Styrofoam -- and explains why Ecovative could be such an important, industry-altering company.

Perhaps arriving soon: the periodical cicada. A "brood" of the fantastically weird insects -- that climb from the ground every 17 years to molt, sing, mate, lay their eggs, and die -- are emerging along the East Coast this month. And we could see some of them in the Capital Region.
This particular cohort of cicadas -- Brood II, or "The East Coast Brood" -- last emerged in 1996. In previous appearances, its range has stretched from North Carolina to northern New York.
Filed under... well, we're not sure: Heather Dewey-Hagborg -- a PhD student in RPI's electronic arts program -- has been creating 3-D "portraits" based on found DNA. From the statement for "Stranger Visions":
In Stranger Visions artist Heather Dewey-Hagborg creates portrait sculptures from analyses of genetic material collected in public places. Working with the traces strangers unwittingly leave behind, Dewey-Hagborg calls attention to the impulse toward genetic determinism and the potential for a culture of genetic surveillance.
A press release from this March explains how she creates the portraits. The process, boiled down: Dewey-Hagborg collects discarded hair, cigarette butts, and chewing gum. She then takes it back to a lab, extracts DNA from the sample, amplifies certain parts of it, then looks for certain segments that are associated with various physical characteristics. The info then goes through a 3-D modeling program and the portrait is printed on a color 3-D printer.
Her website has a bunch of the portraits, along with photos the samples and where they were collected.
We spent 5 years focused on protective packaging. Today it's a huge success, being used to package everything from servers to surf boards. Now we're looking ahead to what's next, and it may be time to return to our roots and dive back into building materials.
This project is a bold experiment to build and grow a house with Mushroom Insulation. We could have started by just building a simple wall assembly and subjecting it to lab tests. And we'll surely be doing that soon. But we thought that starting by building a whole tiny house would lead to more learning (possibly through failure) faster than anything else we could do. Also, we all just think tiny houses are really cool.
Basically, they've built a frame and are letting the mycelium (sort of like mushroom roots) fill in the gaps by bonding together agricultural waste. It's pitched as a environmentally friendly alternative to polystyrene insulation.
The company's set up a site with frequent updates tracking the construction and progress.

Laurie Anderson has a long history of mixing science and art. The experimental artist has invented instruments like a tape bow violin, done a residency at NASA and, for the last year, she's held the first distinguished artist in residence post at EMPAC, where she says science and technology have allowed her to do things she never could have done before.
EMPAC may be a bit of a puzzle to folks outside the media arts world, but inside that world, Anderson says, it's gaining quite a reputation.
"You can't explain it to someone," she says," because there's nothing else like it in the world."
At the corner of 4th and Fulton in downtown Troy, in what was formerly an OTB space on the ground floor of a parking garage, is now a workshop with metal and wood working machinery, racks of tools and parts, 3-D scanners and printers, and biotech equipment.
But organizers see it as part of something even bigger.
1. That sleepy feeling after lunch has a name: the "post-lunch dip."
2. Light, especially red light, might be able to help counteract the dip.
The researchers hooked people up to EEGs to measure brain activity and then exposed them to red (longer wave length) and blue light (shorter wave length). From the abstract:
While the use of light at night to promote alertness is well understood, it is important to develop an understanding of how light impacts alertness during the daytime, especially during the post-lunch hours. The aim of the current study was to investigate how 48-minute exposures to short-wavelength (blue) light ... or long-wavelength (red) light ... close to the post-lunch dip hours affect electroencephalogram measures in participants with regular sleep schedules. Power in the alpha, alpha theta, and theta ranges was significantly lower (p < 0.05) after participants were exposed to red light than after they remained in darkness. Exposure to blue light reduced alpha and alpha theta power compared to darkness, but these differences did not reach statistical significance (p > 0.05). The present results extend those performed during the nighttime, and demonstrate that light can be used to increase alertness in the afternoon, close to the post-lunch dip hours.
The researchers say the work could lead to better understanding how light affects alertness and fatigue in safety situations.
In the meantime, we've found (unscientifically) that a cup of tea helps address the post-lunch dip.

Three physicians/scientists who worked on the development of targeted drugs for cancer treatments are the winners of this year's Albany Medical Center Prize in Medicine and Biomedical Research. At $500k, it's one of the biggest science prizes in the nation.
From the announcement:
This year, the prize will recognize groundbreaking research into the nature of cancer, which has led to the development of a new generation of cancer drugs, most notably Gleevec for chronic myeloid leukemia that, unlike chemotherapy, target specific genetic defects causing cancer.
The recipients are:
+ Peter C. Nowell, M.D., University of Pennsylvania, whose discovery of the "Philadelphia chromosome" in chronic myeloid leukemia established that genetics could be responsible for cancer. + Janet D. Rowley, M.D., University of Chicago, a geneticist who The New York Times called "the matriarch of modern cancer genetics."
+ Brian J. Druker, M.D., Oregon Health & Science University, an oncologist whose research to develop Gleevec saved countless lives and opened the door for more targeted cancer therapies.
You know how people/the media always talk about the promise of genomics for helping to treat diseases? Gleevec is among the most notable examples of that approach.
You might have a picture in mind when you think about maple syrup: a bucket hanging from a tree, smoke from the chimney atop a sugar shack, sap boiling in a cauldron.
While there are places where that picture still fits, modern maple sugaring also involves a range of advances in technology: pipelines, vacuums, evaporators, reverse osmosis machines.
Making maple syrup is a combination of science and craft. And in talking with two local sugarmakers, I found that there are a number of surprising factors that influence both the process and product in making maple syrup. From climate change to soil composition to bacteria in the sap, these are the elements that lead to some of the purest sweet stuff out there, much of which is coming from our backyard in upstate New York.
The Albany County Department of Health reported today that a woman in Cohoes was bitten by a potentially rabid grey fox this morning (area map). The fox got away, and officials are urging people to keep an eye out for wild or stray animals that are acting strangely -- and call 911 if one is sighted.
Rabid foxes turn up now and then in this area. Three foxes tested positive for rabies between January and October of 2012 -- one each in Albany, Rensselaer, and Saratoga counties -- according to the most recent data posted by the state DEC. There were also three positives in 2011 -- two in Saratoga County, and one in Schenectady County. Statewide that year there were 26 positive tests for rabies in foxes, 21 of those in grey foxes.
Back in 2010 a man was bitten by a rabid fox in Greenwich, in a scene that sounds like something from a B movie. From the Daily Gazette:
Richard Leddy, 40, said he was lying on the town beach reading when he heard someone in the water say, "Oh look, there's a fox."
"I thought they meant on the other bank, but then I heard a snarl and looked over to see the fox in mid-leap," Leddy said. "Next think I knew he'd sunk his teeth into my arm."
The animals that most often turn up with positive rabies tests in the state, at least over the last few years, are raccoons and bats. In 2011, there were 162 raccoons that tested positive, and 64 bats. (That's just a raw count of positive tests by the state lab, not a measure of prevalence within the population of those animals compared to other animals.)
In fact, the last two people to die of rabies in New York State -- in 1995 and 1993 -- got it from a bat, according to the state's Wadsworth Center.
The State Museum placed its moon rock on display today in the main lobby. So we stopped by to have a look.
The rock is really just a shard. And stripped of context, it would just elicit a "Huh?" But there is something cool about seeing a piece of the moon. If anything, it traveled a long way to get here.
The state's moon rock is from the Apollo 17 mission -- the last to visit the surface of the moon. It's part of a larger rock ("sample 70017") that two astronauts on the mission -- Eugene Cernan and Ronald Evans -- dedicated to all the young people of Earth. (Groovy, right? Hey, it was the 70s.) Upon their return, Richard Nixon had the rock broken up and the fragments distributed to 135 countries and the 50 US states. The rocks became known as "Goodwill moon rocks." Many of them have gone missing at various points -- New Jersey apparently just flat out lost its rock.
It was kind of fun watching people stop by the exhibit today to gawk at the rock -- especially when a guy engaged one of the security guards in an impromptu discussion of planetary geology.
The rock will be on display until February 10.
Karner blue butterflies typically have two broods per year, one in May/early June and the second in July. The discovery of a third brood is both remarkable and a bit alarming to Preserve scientists because the eggs produced by the July brood of adult Karners typically overwinter to produce adult Karners the following May. An early and very warm spring is the suspected cause of earlier broods this year and the additional late-season butterflies currently flying in the Preserve. The impacts of a third flight of adults to the long-term recovery of the species are unknown. ...
Only time and continued monitoring will determine if the late 2012 hatch will have an impact on the 2013 butterfly population and the longer-term recovery of the species. "We had no idea a third flight in a single season was possible before 2010" said [Albany Pine Bush Preserve Conservation director Neil] Gifford. According to Gifford, it was in 2010 that Karner blue butterfly managers from Wisconsin to New Hampshire suspected that the late season adults they were seeing may be a previously unknown third flight. "We don't yet have a good understanding of what the implications of a third brood will mean for the recovery of the species" said Gifford, adding "it will likely depend on whether the changing climate brings such conditions more frequently."
The preserve says this spring's emergence of Karner Blues was the earliest on record -- 10 days earlier than the previous record, and 21 days earlier than the 20-year average.
To say that the weather over the past year is odd would be an understatement. A handful of the signs and side effects:
As you probably heard, NASA successfully landed a rover -- called Curiosity -- onto the surface of Mars early this morning. It's so easy to be jaded about amazing stuff these days, but this was truly remarkable -- the plan to land the rover was crazy. We realize the scientists and engineers involved probably don't regard it that way, but they used a robot with a supersonic parachute and a sky crane -- to land on Mars!
Ahem. Well, as it happens, Laurie Leshin -- RPI's dean of science -- is part of the science team for Curiosity (her field is cosmochemistry) . She was at the Jet Propulsion Lab in Pasadena for the landing. So, yes, her week is shaping up to be more fun and interesting than yours.
RPI's Approach blog has a quick Q&A with Leshin about the mission and the part with which she's been involved. On what she hopes they find:
I also hope we find a lot of water-bearing minerals that we can characterize very well--carbonites, clays, sulfates--and that can teach us about the aqueous environments on Mars. For most of my career we've thought about Mars as a cold dry place with a potential for a warmer weather past, but not a lot of evidence of it. But that's changing and I think this mission has the potential to really start painting a picture of a more habitable Mars from the past and its potential for habitability in the future.
Bonus bit: here's an op/ed Leshin wrote for the Times Union about the mission -- and its potential for inspiring kids.
And she's on Twitter.
Adult female Karners are captured from New York sites and immediately transported to the rearing facility in Concord, NH. Eggs produced by these butterflies are raised to chrysalises and returned to the Albany Pine Bush Preserve. The adults that emerge are released into restored habitat to begin new colonies. ...
"This is a very exciting, and very limited chance to see this Federally endangered butterfly," says Discovery Center Director Jeffrey Folmer. "One question visitors often ask is 'Where can I see the Karner blues?' These beautiful, but tiny butterflies are rare, hard to spot, live only three to five days and are difficult to distinguish from other similar non-endangered butterflies. We now have 600 of them emerging from their chrysalises one by one and they're on view until they all emerge."
The commission says butterflies will available for viewing at the Albany Pine Bush Discovery Center until mid-July. Admission is free.
The Albany Pine Bush -- a sandy inland pine barren -- is one of the Karner Blue's native habitats (there aren't many remaining). In fact, the butterflies are called "Karner Blues" because of the no-longer hamlet of Karner, New York. Vladimir Nabokov -- yep, the author -- stopped to study the butterflies there in 1950 and ended up naming them. Nabokov once described the insects as being "like blue snowflakes."

Coming to the Schenectady Museum in July: NASA's Driven to Explore Exhibit. From the blurbage:
Immerse yourself in the story of NASA: learn why we explore; discover the challenges of human space exploration; and see how NASA provides critical technological advances to improve life on Earth. And touch a 4 billion-year-old moon rock brought back aboard Apollo 17, the last manned mission to the moon in 1972. The moon rock is one of only eight lunar samples in the world made available for the public to touch.
The mobile exhibit will be at the Schenectady Museum July 12 (noon-9 pm) and 13 (noon-5 pm). The last tickets will be sold an hour before closing. Tickets are $7.50 adults / $5 children / $6.25 seniors / plus $2 for a show at the Suits-Bueche Planetarium.
And, of course, the museum will also be selling astronaut ice cream.
Terence asks via Twitter:
Any reader suggestions for a local destination to look for (not buy) fossils? My son is dying to find a fossil this weekend.
Old quarries, road cuts, and natural cliffs are often good places to find fossils (you'll need to get permission in some cases). [State Museum]
Got a suggestion for Terence and his son? Please share!
Mappage: We came across this CDC map of reported Lyme disease cases over the last decade (ending in 2010). The CDC site allows you to switch from year-to-year -- we piled all those years into the animation above.
The thing that struck us about the map is the way it illustrates how Lyme has spread from the coast and the very central part of the Hudson Valley to the entire Northeast (as well as Wisconsin and Minnesota).
As it happens, the number of reported cases in New York was down noticeably in 2010, the last year for which the data's posted by the CDC. The state's incidence rate that year -- confirmed cases per 100,000 people -- was 12.3 that year (12th highest in the country). It was 21.2 in 2009, and 29.5 in 2008.
Delaware led the nation in 2010 with a rate of 73.1. Vermont's rate was 43.3 that year, and Massachusetts' 36.3.
Earlier this spring a research org in the Hudson Valley -- the Cary Institute for Ecosystem Studies -- reported the "northeastern U.S. should prepare for a surge in Lyme disease this spring." And the reason wasn't the mild winter. Rather, researchers based their projections on mice and acorns:
As strange as it might sound, there were once parrots -- parakeets, specifically -- that were native to New York State. The range of the Carolina Parakeet stretched as far north as the Great Lakes, and there are historical reports of them in Albany.
They were brightly colored. They were loud. And by the late 1800s, they were gone from here. After the early 1900s, they were extinct.
Today's episode of attempted crowdsource entomology: What the heck are these bugs?
Every spring we catch a few of these things scurrying through the house. They seem relatively harmless -- but, you know, they're weird. And some of them are rather large.
We've never encountered them anywhere other than Albany. The topic came up recently with a few friends around here and they, too, had noticed them but had no idea what they are.
So, anyone have the scoop? Please share.

Two molecular biologists from Rockefeller University -- James E. Darnell Jr. and Robert G. Roeder -- are the winners of this year's Albany Medical Center Prize in Medicine and Biomedical Research. At $500,000, the Albany Prize is the largest award for medicine and science in the US.
The two scientists won the prize for their research into how instructions in DNA are copied and transmitted to other parts of the cell (we'll stop before we start talking about RNA). Said Albany Med CEO James Barba in the press release:
"Understanding how our cells express their genetic information provides insight into all of human health. By helping to define how cells grow, replicate, and become specialized, these two scientists have allowed countless other scientists and physicians to explore new ways to fight disease including viruses, heart disease, anemia and autoimmune disorders."
The Albany Prize is funded by a $50 million donation made by philanthropist Morris "Marty" Silverman in 2000. This is the 12th year the prize has been awarded. Last year's award went to a trio of scientists for their work on stem cells.
A group that includes researchers from the State Museum reported in Nature today that it's found evidence of the world's oldest forest floor in Schoharie County. And in this case old means really old -- almost 400 million years ago. The paper made the cover of Nature. [Nature] [NYS Museum]
The spot in Schoharie County -- Gilboa, specifically -- has been notable to paleobotanists for more than a century because of fossilized tree stumps that were found there. The construction of the New York City reservoir system in the 1920s helped uncover more fossils, including foliage imprints. The specimens became known as the "world's oldest trees." Scientists have continued to find other fossil remains that have helped them piece together what these ancient trees probably looked like. In 2007 this same research team -- which includes researchers from Binghamton University and Cardiff University in Wales, as well as the State Museum -- reported that it had found the crown of one of these trees. [Wikipedia] [Gilboa Museum] [Gilboa Museum] [National Geographic] [Nature]
This new discovery helps the researchers piece together what the whole scene looked like.
White Nose Syndrome -- the bat disease first identified in the Capital Region -- has killed as many as 6.7 million bats, according to recent estimates by biologists working with the US Fish and Wildlife Service. Since first being documented in 2006, the disease has now spread to 16 states -- and at many sites it's killed almost 100 percent of the bats. It has some biologists worried that some once-common varieties of bats could be facing extinction. [US FWS] [NYT]
The "white nose" in the syndrome's name refers to a fungus that grows on the face of the bats. Last fall researchers confirmed the fungus was responsible for the syndrome after 100 percent of the bats exposed to it in captivity developed the symptoms in a study. The fungus infects the bats' skin and causes lesions. [Nature News]
In 2010, New York State's Department of Environmental Conservation reported the White Nose Syndrome was likely in all bat caves in the state. The population of some species of bat had declined by 90 percent. [NYS DEC]
The disease was first identified in Howes Cave in Schoharie County -- it spread to other caves in the region and large bat die-offs followed.
Bats don't necessarily have the best reputation with a lot of humans, but they're an important part of the ecosystem because they eat huge numbers of insects -- including mosquitos.

Today's wildlife moment: a posing fisher.
During our email exchange earlier this week with scientist Roland Kays, he passed along two recent clips his wildlife cameras had captured in the Colonie. The first, embedded above, is of a fisher striking a pose in front of a camera just off Sand Creek Road (we're guessing this is the general area):
This camera was ... in a slim strip of forest that connects 2 larger wooded areas (aka core areas). Our GPS tracking of fishers suggested that they used this strip as a movement corridor to get between the larger fragments, we are now testing that by setting cameras out.
We've linked to it before, but here's Kays' "Scientist at Work" series at NYT about tracking fishers in Latham.
The second clip, of raccoons "jogging" over a footbridge near the Hilton Garden Inn at ALB, is after the jump.
We were disappointed to see recently that State Museum curator of mammals Roland Kays was leaving the institution. As the TU reported, morale at the museum is low and many researchers are leaving as a result, Kays among them (be sure to read chrisck's comment).
Kays is one of our favorite local nerds. He researches how wildlife adapt to urban environments. And the conversation we had with him about fishers in the Pine Bush is still one of our favorite AOA posts (that's him weighing a tranquilized fisher in the photo). Also: he was one of the organizers of the popular Cooking the Tree of Life series at the State Museum. The guy even races unicycles.
So, we emailed him to find out what's next. He emailed back:
[Y]es, sad to be leaving the Albany area, but excited about new opportunities at the new Nature Research Center I'm moving to in Raleigh, NC. I'll also be a Prof at NC State. Dr. Jeremy Kirchman will continue the Cooking the Tree of Life at the NYSM, and I'll also start it up down in Raleigh.
Kays says he's also working on a project that will involve non-scientists running camera traps that report images to a wildlife database. He says that could be up and running this summer and he's hoping it will include some sites here in the Capital Region. We'll see if we can get more details as the project's closer to being ready.

Forestry fact of the day: the Adirondacks are one of the areas with the most tree mass in the country, according to a map of "above ground woody biomass" created by the NASA Earth Observatory.
A clip from the map, of New York State, is above. The darker the green, the more tree mass there is.
The national map is posted after the jump in large format. You can see the large swath of forest that runs from Maine, through New Hampshire and Vermont, includes eastern New York, and then runs along the Applachians. And as dense as parts of the swath are, the long, narrow (relatively speaking) forests of the West Coast still trump the East for density of tree stuff (the trees are rather large out there).
Researchers built the map as part of an effort to better understand how much carbon is stored in forests -- and which way that amount is trending.

The folks at theNew York State Museum and Geological Survey confirmed that there was yet another earthquake in the Hilltowns this morning, this time a 2.8 magnitude. So that makes three recent little quakes and one big one (from far away).
Dr. Chuck Ver Straeten at the State Museum said that this morning's quake, which happened in Berne at 9:13 this morning, was the biggest of the three that have gently rocked the area in the past four days. Earthquakes in the Hilltowns are common. Between February of 2009 and March of 2010, there were 37 of them! But Dr. Chuck says they don't have anything to do with each other -- they are all coincidental and all from deep in the earth. More people are just paying attention to earthquakes this week because of the one in Virginia that was also relatively mild.

GE has posted images from the guest book for the company's original research center in Schenectady (GE Global Research is now in Niskayuna):
While its beginnings were humble, it didn't take long for scientists and inventors from around the world to flock to the Research Lab to see what GE was working on. And each famous mind that visited would stop at Willis Whitney's desk to sign the VIP guest book. The book sat at Whitney's desk from 1914 to 1935, and the signatures are a veritable Who's Who of inventors, physicists, chemists, physiologists, and businessmen -- including 9 Nobel Laureates.

The first flight of Karner Blue butterflies should be appearing in their habitats around the Capital Region right about now.
The beautiful endangered butterflies hang around sandy pine barren habitats. Two such spots in the Capital Region: the Albany Pine Bush Preserve and the Wilton Wildlife Preserve. Drew was at the Wilton preserve this past week and said the butterflies were easy to spot.
There's some great history Capital Region history involving the Karner Blue. The common name of the butterflies is linked to a spot here -- and Vladimir Nabokov classified the butterflies. Yep, the author.
While out walking Otto today we noticed the pear trees -- with their white blossoms and, uh, distinctive odor -- are back in bloom. As Ryan wrote for AOA last year (almost a year to the day):
Which brings us finally to this: why does this tree smell so horrible? As far as I can tell, there isn't any research on why exactly the trees stink. However, I did come up with this: all of the approximately 30 species of pear contain the aroma compound pentyl butanoate. I will spare you the biochemistry -- this is the compound that makes pears and apricots smell as they do. One the precursors of pentyl butanoate is butyric acid, which is present in butter, parmesan cheese and... vomit.
Ryan's post also gets into the history of the trees and why they're everywhere (despite the stink).
There's a new (old) way to combat invasive plant species in upstate New York: small flocks of sheep.
Gary Kleppel, a professor of biological sciences at UAlbany and director of the Biodiversity Conservation and Policy Program there, is in the process of setting up a "targeted grazing" project using sheep at Albany's city-owned Normanskill Farm.
His sheep start arriving in a few weeks and then, with the help of students, dogs, and a fancy fence, the sheep get to work -- eating and gnawing at the plants that cause problems for our ecosystem.
Nick Fahrenkopf has written an interesting post about Joseph Henry, one of Albany's all-time great nerds:
Henry has been immortalized in more than the UAlbany physics building, his early school, a monument near the original Albany Academy, and buildings in Princeton: the unit of induction is the henry and the medal for service to the Smithsonian is the Henry Medal. Even a mountain range bears his name. Back here in Albany, the church where he was baptized even has a stained glass window of Henry lecturing 12 disciples with the words "Master Scientist and Devout Christian". I find it fascinating that now, over a hundred years later this area is home to the next wave of science and technology that will propel our nation forward. Not the Weather Service, Lighthouses, or telegraphs. But nanoelectronics, solar panels, biomedical engineering. It just seems... fitting.
Among many accomplishments, Henry was instrumental in discoveries on electromagnetism, the beginning of the Smithsonian, and the creation of the National Weather Service.

Block is an expert on alliums -- that is, plants such as onions and garlic. From McGee's piece:
"It's still astounding to me what happens when you cut or bite into an onion or a garlic clove," Dr. Block told me in a telephone conversation last month. "These plants originated in a very tough neighborhood, in Central Asia north of Afghanistan, and they evolved some serious chemical weapons to defend themselves."
Their sulfur-based defense systems give the alliums their distinctive flavors. The plants deploy them when their tissues are breached by biting, crushing or cutting. The chemicals are highly irritating, and discourage most creatures from coming back for seconds. They kill microbes and repel insects, and they damage the red blood cells of dogs and cats. Never feed a pet onions or garlic in any form. ...
Dr. Block explains that different alliums stockpile different sulfur chemicals to make their weapons, and this accounts for their varying flavors. The stockpiles themselves are inert, but when the plant's tissues are damaged, enzymes in the tissues quickly convert the sulfur compounds into reactive, stinging molecules.
There a bunch of interesting bits in the article -- whether you cook, or just eat.
Block wrote a recently-published book about alliums, Garlic and Other Alliums: The Lore and the Science. The book blurb says it "outlines the extensive history and the fascinating past and present uses of these plants."
Block co-authored a 2007 paper in the Archives of Internal Medicine that reported the neither raw garlic nor garlic supplements appeared to have clinically significant effects on cholesterol levels in people.
Where are the wild things? Lately, it seems the answer is here. And by here, we mean our backyard. And your backyard.
Over the last month, there have been moose sightings in Saratoga and East Greenbush, a bear spotted in Troy and reports of rabid foxes. Every few weeks someone drops into AOA to post a comment about a fisher sighting. And we seem to be hearing about coyotes a lot more, too.
So, what's going on? We called up Roland Kays, the mammal curator at the New York State Museum, for some answers. He studies urban wildlife.
Roland says some of these sightings are probably just part of the cycle of young animals heading out on their own for the first time. But he says there's a bigger story here, too: wild animals are moving into our neighborhoods. And that's a good thing.
The board that manages New York State's stem cell research funding has given the OK for researchers to pay women for their eggs (the technical term is "oocytes"). And not just a few bucks, either. The Empire State Stem Cell Board has approved payments up to $10,000.
New York is the first state to allow its research money to be used this way. Guidelines from the federal National Academies of Science "prohibit cash or in-kind payments for donating oocytes for research purposes."
Summer's comment about the Mohawk this morning prompted us to go looking for info about the river's water levels. And, as it turns out, there's a bunch of data posted on online -- something to keep in mind if you're a boater, fisherperson or other river user of some sort.
The US Geological Survey posts some pretty simple river level graphs created from data taken at a station in Cohoes. And the National Weather Service uses that data to create a whole bunch of graphs, charts and forecasts for points in Schenectady and Cohoes.
Bonus river data: the USGS service that tracks the Mohawk also tracks rivers and streams all over the state. As you might expect, this list includes the Hudson (here's the reading near Green Island) -- but also smaller streams such as the Normanskill.

The site of last night's earthquake -- well, here, but 9 km down.
There was another earthquake last night near Berne -- and it was relatively big (for this area).
The seismographic network that monitors this area reports that quake was a 3 on the magnitude scale ("felt quite noticeably by persons indoors, especially on upper floors of buildings"). There are reports that people did feel this one.
Things have been a little shaky in the Hill Towns recently. Over just the last three months there have been 14 earthquakes. Most of them have been tiny. The one last night was the strongest of the group.

Gerwin Schalk, who got his PhD at RPI, is developing software that processes and translates brain signals into action. He and other researchers at Wadsworth helped develop the "keyboard" for the brain-to-Twitter device.
Wadsworth has gained attention over the last few years for its researchers' work on brain-computer interfaces. The institute's Jonathan Wolpaw was on 60 Minutes last year as part of a story about the technology.
A piece looked at how a brain-computer interface developed by Wadsworth's Jonathan Wolpaw is helping people with conditions such as ALS communicate with the world. The device allows people to control a computer just by thinking.
