Rutgers student Julia Van Etten, whose @Couch_Microscopy Instagram page garnered more than 25,000 followers by showcasing microorganisms as art, is now working with NASA on research into how red algae can help explain the origins of life on Earth.
Tens of thousands of reservoir and dam systems are being operated in communities across the United States, ensuring access to reliable sources of water. That access, however, isn’t a guarantee. Altered rainfall patterns driven by global warming, increased urbanization, and growing populations are setting up parallel increases in demand for water and energy. Sustainable approaches to managing these systems are a critical part of the solution. To that end, mechanical engineers at Rensselaer Polytechnic Institute are developing a better understanding of how water and sediment flow through reservoirs and dams, in the hopes of making that process closer to earth’s natural dynamics. Their work is being supported by a National Science Foundation Faculty Early Career Development (CAREER) grant.
The researchers have already confirmed their discovery in human tissue samples and used it to reverse high blood pressure in lab mice.
A room-temperature bonding technique for integrating wide bandgap materials such as gallium nitride (GaN) with thermally-conducting materials such as diamond could boost the cooling effect on GaN devices and facilitate better performance through higher power levels, longer device lifetime, improved reliability and reduced manufacturing costs.
People with serious mental illness report that poor physical health rather than their mental health condition creates barriers to job searching, according to a Rutgers study.

Many farmers struggle with an enemy that looks like a friend. Agricultural weeds that are close relatives of crops present a particular challenge to farmers because their physical similarities to the desirable species make them difficult to detect and eradicate. Along the way, the imitators compete with crops for water, nutrients and space — often depressing crop yields.
The Federal Communications Commission (FCC) will invest $176 million over 10 years to connect Missourians in rural areas to high-speed internet. But with more than 1 million residents who need access, systems expert Dr. Casey Canfield says bridging the digital divide will also take an investment in broadband research. “Analytical research can help decision-makers make more strategic investments in broadband infrastructure by using simulations to compare different approaches,” says Canfield.
Johns Hopkins Medicine scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes. The findings from this experimental study, they say, advance regenerative medicine techniques aimed at reversing the course of diabetic retinopathy and other blinding eye diseases.
Propagating Motor Cortical Dynamics Facilitate Movement Initiation
New discovery in breast cancer could lead to better strategies for preventing the spread of cancer cells to other organs in the body, effectively reducing mortality in breast cancer patients. According to a study, published today in Nature Cell Biology, breast cancer cells shift their metabolic strategy in order to metastasize. Instead of cycling sugar (glucose) for energy, they preferentially use mitochondrial metabolism.

In the past, biologically-active peptides – small proteins like neurotoxins and hormones that act on cell receptors to alter physiology – were purified from native sources like venoms and then panels of variants were produced in bacteria, or synthesized, to study the structural basis for receptor interaction. A new technique called zombie scanning renders these older processes obsolete.
More than half of the planet’s fresh water is in Antarctica. While most of it is frozen in the ice sheets, underneath the ice pools and streams of water flow into one another and into the Southern Ocean surrounding the continent. Understanding the movement of this water, and what is dissolved in it as solutes, reveals how carbon and nutrients from the land may support life in the coastal ocean.

Researchers at the University of Rhode Island (URI) used San Diego Supercomputer Center’s (SDSC) Comet supercomputer to show that high-performance computer modeling can accurately simulate tsunamis from volcanic events. Such models could lead to early-warning systems that could save lives and help minimize catastrophic property damage.
An artificial intelligence (AI) device that has been fast-tracked for approval by the Food and Drug Administration may help identify newborns at risk for aggressive posterior retinopathy of prematurity (AP-ROP). AP-ROP is the most severe form of ROP and can be difficult to diagnose in time to save vision.
A $6 million grant from Arnold Ventures will support replication and rigorous study of the outcomes of the Transitional Care Model (TCM) in four U.S. health care systems. Designed by a team at the University of Pennsylvania School of Nursing (Penn Nursing), the TCM has been proven in multiple National Institutes of Health (NIH)-funded randomized clinical trials (RCTs) to improve health outcomes, reduce rehospitalizations and decrease total health care costs among the growing population of Medicare beneficiaries.
A “decoy” mechanism has been found in human and animal cells to protect them from potentially dangerous toxins released by foreign invaders, such as bacteria.
Johns Hopkins Medicine researchers report that the number of disabled students admitted to U.S. medical schools rose from 2.9% to 4.9% over the last three years. However, the percentage of NIH-funded researchers with disabilities declined between 2008 and 2018. The grant success rate for this group was lower than for researchers without a disability, indicating that despite more people with disabilities prepared to enter biomedical research, their prospects as professionals are weakening.
A new culprit — hydrogen sulfide — worsens the deadly disease tuberculosis. When Tb bacteria invade the lung, the amounts of hydrogen sulfide in the lung microenvironment greatly increase, and this makes the microbe more virulent and better able to block the body’s protective immune response.
The U.S. Department of Energy is investing $74 million dollars in research to develop and test technologies and construction practices that will help “improve the energy performance of the nation’s buildings and electric grid.” The Lighting Enabled Systems & Applications (LESA) Center, housed at Rensselaer Polytechnic Institute, will receive more than $2.8 million as part of this nationwide effort.

Statistics can’t show how any one person will respond to a reatment.works in people. Dr. Sarah Adams is using a $1.2M to find better ways to predict which women will benefit from her drug combination, now in clinical trials.
Turning adhesion on and off is what makes a glue smart. Inspired by nature, catechols are synthetic compounds that mimic the wet-but-still-sticky proteins found in mussel feet and offer promise for underwater glue, wound dressings, prosthetic attachments or even making car parts and in other manufacturing. A Michigan Tech team has used electricity for the first time to deactivate a catechol-containing adhesive in salt water.
