New Coating for Medical Devices Repels Blood and Bacteria

Using materials already approved by the FDA, Harvard engineers have developed a new surface coating for medical devices that repels blood and suppresses biofilm formation. Most any medical device implanted in the body — or one that comes into contact with flowing blood, such as a dialysis machine — may also present two critical challenges […]

Scientists Restore Hearing in Mice

Using advanced tools to boost the production of a key protein in the ears of mice, a team of scientists has restored the hearing of mice partly deafened by noise. By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research […]

Lizard Study Shows Trade is a Force in Biodiversity

A newly published study shows that trade is one of the major drivers of biodiversity among lizard species in the Caribbean islands, finding that the amount of trade an island receives can explain to a large extent the number of invasive species on an island. It may be a cliché to say it, but the […]

Research Reveals Coffee Drinking Habits Shaped by Genetic Variations

A study by the international Coffee and Caffeine Genetics Consortium looked at DNA samples and data sets from the coffee-drinking habits of 120,000 people of European and African-American ancestry, providing insight on why caffeine affects people differently, and how these effects influence coffee-drinking behavior. An international research team has found six new genes underlying our […]

Theorists Discover a New Way to Improve Solar Cell Efficiency

Researchers at MIT and Harvard have discovered a way of rendering excitons immune to getting stuck in minuscule defects as they hop through a material, which could possibly lead to improving efficiency in photovoltaic devices. A major limitation in the performance of solar cells happens within the photovoltaic material itself: When photons strike the molecules […]

Study Shows Deadly Violence a Natural Tendency in Chimps

Using data collected from 18 chimpanzee research sites, a newly published study shows that chimps engage in violent and sometimes lethal behavior regardless of human effects on local ecology. For decades, scientists studying chimpanzees in the wild have noted the ways our closest relatives are similar to humans — they form tightly knit social groups, […]

Researchers Use Biofilms to Create Self-Healing Materials

A newly published study details how researchers at Wyss Institute for Biologically Inspired Engineering at Harvard University are using biofilms to create self-healing materials and other technologies. For many people, biofilms conjure up images of slippery stones in streambeds or dirty drains. A team at the Wyss Institute for Biologically Inspired Engineering at Harvard University […]

Wyss Institute to Further Develop Its Soft Exosuit

Wyss Institute has won a DARPA grant to further develop their lightweight Soft Exosuit. The Exosuit is pulled on like a pair of pants and is intended to be worn under a soldier’s regular gear, providing carefully timed assistance at the leg joints without restricting the wearer’s movement. A biologically inspired smart suit that fits […]

Evolution of Flies, Worms and Humans Share Patterns of Gene Expression

Several newly published studies reveal that flies, worms and humans share ancient patterns of gene expression. Although separated by hundreds of millions of years of evolution, flies, worms, and humans share ancient patterns of gene expression, according to a massive Yale-led analysis of genomic data. Two related studies led by scientists at Harvard and Stanford, […]

New Research Could Lead to Therapeutic Strategies for Autism

Scientists from Harvard University and the Max-Planck Institute unravel a neural circuit that could play an important role in autism. The insular cortex is an integral “hub”, combining sensory, emotional and cognitive content. Not surprisingly, alterations in insular structure and function have been reported in many psychiatric disorders, such as anxiety disorders, depression, addiction and […]

A New Way to Regrow Human Corneas

Harvard-affiliated researchers have discovered a new way to regrow human corneas that could help researchers overcome a major cause of blindness. Researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule that acts as a marker for hard-to-find limbal stem cells. This work, a collaboration among the […]

Harvard Stem Cell Institute Researchers Show that GDF11 Improves Functioning of Aged Brains and Muscles

In two new studies, researchers from the Harvard Stem Cell Institute show that injections of GDF11 improved the exercise capability and the function of the olfactory region of the brain in older mice. Harvard Stem Cell Institute (HSCI) researchers have shown that a protein they previously demonstrated can make the failing hearts in aging mice […]
