  • The Jefferson Papers - Changing forests, insecticides, and wetland ecosystems

    November 9, 2017 -

    The Jefferson Project at Lake George is conducting research into how human activities may affect the lake, which include attached wetlands and the surrounding watershed. Here, we summarize research on the combined effects of changing forests and a commonly applied insecticide on wetland ecosystems, which was published recently in the journal Environmental Pollution.

  • The Jefferson Papers - Forests, Road Salt and Wetlands Ecosystem Research Published

    November 9, 2017 -

    The Jefferson Project at Lake George is conducting research into how human activities may affect the lake. Here, we summarize research on the effects of road salt and changing forest composition on wetland ecosystems, which was published recently in the journal Freshwater Science .

  • Picture of the Day: Can environmental toxins disrupt the biological clock?

    November 7, 2017 -

    Can environmental toxins disrupt circadian rhythms -- the biological clock whose disturbance is linked to chronic inflammation and a host of human disorders? Research showing a link between circadian disruption and plankton that have adapted to road salt pollution puts the question squarely on the table. The research builds on recent findings from the Jefferson Project at Lake George, showing that a common species of zooplankton, Daphnia pulex (shown here), can evolve tolerance to moderate levels of road salt in as little as two and a half months. That research produced five populations of Daphnia adapted to salt concentrations ranging from the current concentration of 15 milligrams-per-liter of chloride in Lake George to concentrations of 1,000 milligrams-per-liter, as found in highly contaminated lakes in North America.

  • WE’RE POURING MILLIONS OF TONS OF SALT ON ROADS EACH WINTER. HERE’S WHY THAT’S A PROBLEM.

    November 7, 2017 -

    Despite the ever-greater use, road salt’s effects on streams, lakes and groundwater have been largely ignored until recently. As recently as 2014, when biologist Rick Relyea began studying the effects of salt-laden runoff at Rensselaer Polytechnic Institute, “the world of science didn’t pay very much attention to the impacts of road salt on water,” he says. “Now we’re paying much more attention.”

  • The scientific swerve: Changing your research focus

    October 10, 2017 -

    Many scientists alter their research focus, at least slightly, over their career, according to studies by Boleslaw Szymanski, a computer science professor at Rensselaer Polytechnic Institute in Troy, New York. Szymanski’s group followed the work of more than 14,000 scientists from 1976 to 2009, using data from American Physical Society journals. The results showed that most researchers tend to stay in their field, but that those who don’t progress along a related path. In describing their findings, Szymanski and colleagues use an analogy inspired by Isaac Newton’s reflection on his own research: They describe a scientific career as a walk along the beach, moving from one interesting shell (in this case a research topic) to another. 

    These findings support a similar analysis that Szymanski’s group performed on data from journals and from U.S. National Science Foundation (NSF) grants in computer science. In this field, scientists tend to shift research focus roughly every 10 years. Some make once-in-a-career moves to substantially different areas. The field itself changes with technological advances, Szymanski says, so even researchers who stay in one area at least change methods over time. 

  • Hackers converge on RPI campus

    July 6, 2017 -

    Hundreds of students spent their weekend hacking away, competing in the third annual HackRPI marathon. The 24-hour, two-day event drew about 300 students from a wide range of schools to the Rensselaer Polytechnic Institute campus.

  • Alexa, What's The Future Of AI?

    July 6, 2017 -

    Once upon a time, we dreamed of artificial intelligence in outer space, in a sci-fi future, far from home. Now, we’re talking with computers in our kitchens.  Asking them anything. “Alexa, what’s the Inaugural Oath?” “How big is a blue whale?” “What’s the square root of seven trillion forty two?” Does this ambient, ask-it-anything-anytime AI give us superpowers? Make us great? Make us lazy? And what comes next? This hour On Point,  talking with Alexa, and humans, about the AI future. — Tom Ashbrook

  • The Internet of Things Needs a Code of Ethics

    July 6, 2017 -

    In October, when malware called Mirai took over poorly secured webcams and DVRs, and used them to disrupt internet access across the United States, I wondered who was responsible. Not who actually coded the malware, or who unleashed it on an essential piece of the internet’s infrastructure—instead, I wanted to know if anybody could be held legally responsible. Could the unsecure devices’ manufacturers be liable for the damage their products?

    Right now, in this early stage of connected devices’ slow invasion into our daily lives, there’s no clear answer to that question. That’s because there’s no real legal framework that would hold manufacturers responsible for critical failures that harm others. As is often the case, the technology has developed far faster than policies and regulations.

    But it’s not just the legal system that’s out of touch with the new, connected reality. The Internet of Things, as it’s called, is also lacking a critical ethical framework, argues Francine Berman, a computer-science professor at Rensselaer Polytechnic Institute and a longtime expert on computer infrastructure. Together with Vint Cerf, an engineer considered one of the fathers of the internet, Berman wrote an article in the journal Communications of the Association for Computing Machinery about the need for an ethical system.

  • The Hidden Dangers of Road Salt

    May 30, 2017 -

    “It has a really widespread number of effects on the whole food web or ecosystem,” says Rick Relyea, a professor of biological sciences at Rensselaer Polytechnic Institute. Relyea has studied how road salt runoff impacts lakes as part of the Jefferson Project at Lake George in New York state. Recently, he found that road salt can reduce the size of rainbow trout hatchlings by about 30 percent, influencing their ability to elude predators and decreasing the number of eggs they lay. One experiment he worked on found that higher levels of salt could change the male-female sex ration of wood frogs.

  • RPI's Hendler On What We Are Learning From Election Data

    November 15, 2016 -

    The numbers from the election are still coming in, but one analysis indicates that despite what many of the pundits believe, the Trump victory was not driven as much by the white working class, but more by the fact that Democrats stayed home. Jim Hendler is the Director of the Institute of Data Exploration and Applications at RPI. He says while the numbers are still preliminary, it is clear that the Clinton campaign failed to get enough Democrats to the polls.

  • Research pair outlines new field of 'web science'

  • Heparin derived from cattle is equivalent to heparin from pigs, study finds

    October 6, 2016 -

    As demand for the widely used blood thinning drug heparin continues to grow, experts worry of possible shortages of the essential medication. Heparin is primarily derived from pigs, and to reduce the risk of shortages, cattle have been proposed as an additional source. A new study by a team of researchers, including corresponding author Robert J. Linhardt, and nine co-authors from Rensselaer Polytechnic Institute. has found that heparin derived from cattle (known as bovine heparin) has equivalent anti-clotting properties to heparin derived from pigs (porcine heparin).

  • Comet may have struck Earth just 10 million years after dinosaur extinction

    September 30, 2016 -

    Some 56 million years ago, carbon surged into Earth's atmosphere, raising temperatures by 5°C to 8°C and causing huge wildlife migrations—a scenario that might mirror the world's future, thanks to global warming. But what triggered this so-called Paleocene-Eocene thermal maximum (PETM) has remained a mystery.

  • Glass bits, charcoal hint at 56-million-year-old space rock impact

    September 30, 2016 -

     A period of skyrocketing global temperatures started with a bang, new research suggests.

    Too little is known about the newfound impact to guess its origin, size or effect on the global climate, said geochemist Morgan Schaller of Rensselaer Polytechnic Institute in Troy, N.Y. But it fits in with the long-standing and controversial proposal that a comet impact caused the PETM. “The timing is nothing short of remarkable,” said Schaller, who presented the discovery September 27 at the Geological Society of America’s annual meeting.

While areas to the north and south of Illapel — where the Nazca plate dives beneath the South American plate — have been studied, until now the complexity of the boundary in the area of Illapel has deterred research.

  • How A 'Nightmare' Law Could Make Sharing Passwords Illegal

    July 15, 2016 -

    People share passwords all the time. A husband might give his wife his bank account login so she can pay a bill. A professor might ask a secretary to check emails. Comedian Samantha Bee's segment on Syrian refugees featured her teaching them essential phrases in U.S. culture, including "Can I have your HBO Go login?"

    But a recent federal court ruling has advocates, researchers and the dissenting judge worried that sharing passwords, even in seemingly innocuous circumstances, could be considered illegal. That's because the anti-hacking law used is so vague that Columbia law professor Tim Wu called it "a nightmare for a country that calls itself free."

  • Heidi Newberg, RPI – The Size of the Galaxy

    July 15, 2016 -

    This universe of ours is pretty big, and it might be bigger than we think.

    Heidi Newberg, astronomer and physicist at Rensselaer Polytechnic Institute, is studying the size of the galaxy.

    Dr. Heidi Newberg has worked in many areas of astronomy over the course of her career. She did her Ph.D. with the Berkeley Automated Supernova Search, which measured the supernova rates as a function of supernova type in Virgo-distance galaxies; and the Supernova Cosmology Project (SCP), which is measured the cosmological parameters Omega and Lambda using the light curves of distant supernovae. She shared the Gruber Cosmology Prize for her work with SCP.

  • Scientists Explore Properties Of Wonder Material Phosphorene

    May 19, 2016 -

    In a collaborative and multidisciplinary study, scientists develop methods to explore phosphorene and its properties. Phosphorene, discovered in 2014, is related to the two-dimensional graphene and has been established to have numerous photonic applications. The majority of these properties, however, is its capacity for anisotropic electron conduction. This means that its electron conduction property changes depending on the crystal orientation.

  • Fear Not, AI May Be Our New Best Partners in Creative Solutions – A Conversation with Dr. James Hendler

    April 7, 2016 -

    Statements about AI and risk, like those given by Elon Musk and Bill Gates, aren’t new, but they still resound with serious potential threats to the entirety of the human race. Some AI researchers have since come forward to challenge the substantive reality of these claims. In this episode, I interview a self-proclaimed “old timer” in the field of AI who tells us we might be too preemptive about our concerns of AI that will threaten our existence; instead, he suggests that our attention might be better  honed in thinking about how humans and AI can work together in the present and near future.

  • Totally Wired: State Grant Helps Jefferson Project Complete Web of Lake Sensors

  • Jefferson Project to expand research gathering

    February 22, 2016 -

    This year, researchers will have a more complete understanding of Lake George than ever before.

    The remaining 21 sensor platforms that have yet to be deployed as part of The Jefferson Project at Lake George are scheduled to take their places in and around the lake by the end of this year. So far, 20 have been deployed, mostly in the southern basin and the Narrows. This year, data-collecting and transmitting sensors will be deployed in and around the northern end of the lake.

    The sensor network, made of four types of sensor platforms, collects massive amounts of information from the lake, its tributaries and wetlands, and sends data to supercomputers for analyses.

    “We’ll try to complete that picture. We have about half the picture now,” said Jefferson Project Director Rick Relyea.

  • State funding pushes Lake George research project to finish

    Every day, every hour or so, the Minne Ha Ha departs the Steel Pier, its chirping steam whistles, calliope licks  and  the  bright  foam  of  its paddle wheel infusing the air with a holiday sweetness. Who knew that it’s actually a research vessel?

  • Frogs mount speedy defence against pesticide threat

    August 18, 2015 -

    This is the first-known example of a vertebrate species developing pesticide resistance through a process called phenotypic plasticity, in which the expression of some genes changes in response to environmental pressure. It does not involve changes to the genes themselves, which often take many generations to evolve.

    The frogs' speedy response raises hope for amphibian species, of which one-third are threatened or extinct, says Rick Relyea, an ecologist at the Rensselaer Polytechnic Institute in Troy, New York, and the team's leader.
