Machine Learning Approach for Low-Dose CT Imaging Yields Superior Results
TROY, N.Y. —Machine learning has the potential to vastly advance medical imaging, particularly computerized tomography (CT) scanning, by reducing radiation exposure and improving image quality.
Those new research findings were just published in Nature Machine Intelligence by engineers at Rensselaer Polytechnic Institute and radiologists at Massachusetts General Hospital and Harvard Medical School.
International Bioartists To Speak at Rensselaer on April 25 and May 8
To highlight the important connections that exist between art, science, and technology, Rensselaer Polytechnic Institute will host lectures with international bioartists on April 25 and May 8. The events, presented by the Arts Department in the School of Humanities, Arts, and Social Sciences (HASS) at Rensselaer, are free and open to the public.
Sugar Entering the Brain During Septic Shock Causes Memory Loss
The loss of memory and cognitive function known to afflict survivors of septic shock is the result of a sugar that is released into the blood stream and enters the brain during the life-threatening condition.
Multiple Mechanisms Behind Disease Associated With Unexpected Heart Attacks
Research on three mutations associated with hypertrophic cardiomyopathy –a disease best known for revealing itself as an unexpected, fatal heart attack during strenuous exercise – found separate mechanisms at work at the molecular level.
Improving Molecular Imaging using a Deep Learning Approach
TROY, N.Y. — Generating comprehensive molecular images of organs and tumors in living organisms can be performed at ultra-fast speed using a new deep learning approach to image reconstruction developed by researchers at Rensselaer Polytechnic Institute.
The research team’s new technique has the potential to vastly improve the quality and speed of imaging in live subjects and was the focus of an article recently published in Light: Science and Applications, a Nature journal.
Carbon Capture Research Receives $3 Million from U.S. Department of Energy
TROY, N.Y. — The United States Department of Energy (DOE) has announced that a research project at Rensselaer Polytechnic Institute is one of eight in the nation recently selected to receive federal funding geared toward the development of “novel and enabling carbon capture transformational technologies.”
Big Data Approach Shown To Be Effective for Evaluating Autism Treatments
Researchers at Rensselaer Polytechnic Institute who developed a blood test to help diagnose autism spectrum disorder have now successfully applied their distinctive big data-based approach to evaluating possible treatments.
Salt-Evolved Zooplankton Grow Too Slowly To Block Salt-Induced Algal Blooms
Small animals at the base of the freshwater food chain can rapidly adapt to salt pollution – from sources like winter road deicing, agriculture, and mining – but at a price.
Research Focuses on a New Frontier in Circadian Rhythms
A new frontier in the science of circadian rhythms – whose disruption is linked to major diseases like cancer and diabetes – suggests a previously unknown mechanism at work in our daily biological cycle.
Biocatalysis Expert Richard Gross Recognized for Economical Environmental Chemical Advances
The American Chemical Society (ACS) has recognized biocatalysis expert Richard Gross with the 2019 ACS Award for Affordable Green Chemistry, bestowed for outstanding scientific discoveries or chemistries that lay the foundation for cost-competitive environmentally friendly products or manufacturing processes that are less expensive than existing alternatives.
Flipped Cells Cause Blood Vessels To Leak in Diabetes and Other Diseases
An enzyme activated in diabetics has been found to cause previously aligned cells in a blood vessel to reverse their orientation, creating misalignments that allow veins and arteries to leak three times more blood proteins than normally constructed blood vessels.
Research Seeks Candidates for Alzheimer’s Drug to Block Production of Amyloid Peptide
With support from the Warren Alpert Foundation, researchers at Rensselaer Polytechnic Institute have launched a search for drug candidates to block a biological process associated with Alzheimer’s disease.

For healthier lakes, rivers, and drinking water, hold the salt
February 6, 2019 -Rick Relyea, an environmental scientist at Rensselaer Polytechnic Institute, is tackling similarly thorny questions in upstate New York’s Lake George, which has been called the Queen of American Lakes. Relyea leads the Jefferson Project, a collaboration among RPI, IBM, and the FUND for Lake George, a nonprofit focused on conserving the lake. The project has outfitted the lake with more than 500 “smart” environmental sensors during the past four years to monitor human influence on it. Over the past four decades, according to data from the Lake George Offshore Chemical Monitoring Program, chloride levels have tripled in Lake George, adding to other environmental effects on the lake. These effects include the rise of invasive species and the delivery, through stormwater runoff, of pollutants and nutrients that can stimulate algal blooms. Because it’s hard to tease apart the impacts of these various stressors on the lake’s water quality and wildlife, Relyea’s team has done a bevy of experiments in the lab and in large outdoor tanks to isolate and examine the consequences of increasing salt.

Freshwater Is Getting Saltier, Threatening People and Wildlife
December 21, 2018 -Salts that de-ice roads, parking lots and sidewalks keep people safe in winter. But new research shows they are contributing to a sharp and widely rising problem across the U.S. At least a third of the rivers and streams in the country have gotten saltier in the past 25 years. And by 2100, more than half of them may contain at least 50 percent more salt than they used to. Increasing salinity will not just affect freshwater plants and animals but human lives as well—notably, by affecting drinking water.
