Load-reducing backpack powers electronics by harvesting energy from walking

Hikers, soldiers and school children all know the burden of a heavy backpack. But now, researchers have developed a prototype that not only makes loads feel about 20% lighter, but also harvests energy from human movements to power small electronics. The new b

Remyelinating drug could improve vision in patients with multiple sclerosis

Biomedical scientists reports a drug -- an estrogen receptor ligand called indazole chloride (IndCl) -- has the potential to improve vision in patients with multiple sclerosis, or MS. The study was performed on mice induced with a model of MS and the first t

Researchers have identified key variants that help explain the differences between the viruses that cause COVID-19 and Severe Acute Respiratory Syndrome (SARS).

Scientists advocate breaking laws - of geography and ecology

All that's local is a lot more global, and scientists say solutions can only be found through broader views and collaborations nearby and far away.

Injection to treat skin cancer developed

Yale researchers are developing a skin cancer treatment that involves injecting nanoparticles into the tumor, killing cancer cells with a two-pronged approach, as a potential alternative to surgery.

Arctic shrubs add new piece to ecological puzzle

A 15-year experiment on Arctic shrubs in Greenland lends new understanding to an enduring ecological puzzle: How do species with similar needs and life histories occur together at large scales while excluding each other at small scales? Its findings also reve

Sea level will rise faster than previously thought

There are two main elements to observe when assessing sea level rise. One is the loss of the ice on land and the other is that the sea will expand as it gets warmer. Researchers have constructed a new method of quantifying just how fast the sea will react to

COVID-19 lockdowns temporarily raised global temperatures, research shows

The lockdowns and reduced societal activity related to the COVID-19 pandemic affected emissions of pollutants in ways that slightly warmed the planet for several months last year, according to new research. The counterintuitive finding highlights the influenc
