From heat to spin to electricity: Understanding spin transport in thermoelectric devices
Thermoelectric materials, which can generate an electric voltage in the presence of a temperature difference, are currently an area of intense research; thermoelectric energy harvesting technology is among our best shots at greatly reducing the use of fossil fuels and helping prevent a worldwide energy crisis. However, there are various types of thermoelectric mechanisms, some of which are less...
People's acceptance of inequality affects response to company wrongdoings
People who do not accept inequality are more likely to negatively evaluate companies that have committed wrongdoings than people who do accept inequality, and this response varies by culture, according to researchers at Penn State. The team also found that companies can improve their standing with consumers when they offer sincere apologies and remedies for the harm they caused to victims.
Scholars reveal the changing nature of US cities
Cities are not all the same, or at least their evolution isn't, according to new research from the University of Colorado Boulder.
Immune system sets 'tripwire' to protect against viruses
Scientists are opening new windows into understanding more about the constantly shifting evolutionary arms race between viruses and the hosts they seek to infect. Host organisms and pathogens are in a perennial chess match to exploit each other's weaknesses.
New biosensors quickly detect coronavirus proteins and antibodies
Scientists have created a new way to detect the proteins that make up the pandemic coronavirus, as well as antibodies against it. They designed protein-based biosensors that glow when mixed with components of the virus or specific COVID-19 antibodies. This breakthrough could enable faster and more widespread testing in the near future. The research appears in Nature.
Experiments show the record of early life could be full of 'false positives'
For most of Earth's history, life was limited to the microscopic realm, with bacteria occupying nearly every possible niche. Life is generally thought to have evolved in some of the most extreme environments, like hydrothermal vents deep in the ocean or hot springs that still simmer in Yellowstone. Much of what we know about the evolution of life comes from the rock record, which preserves rare...
Covid apps could get a second chance under Biden—but it will take work
As the Biden administration ramps up, it inherits soaring cases and a muddled vaccine rollout— so it’s reasonable to wonder what else can possibly slow the spread of covid-19. Some strategies in the administration’s covid plan are basics, like calling on people to wear masks, doing more testing, and communicating more clearly. But digital technology gets a nod, too: tucked into a list of...

Scientists used high-performance TEM to image the process of gold atoms assembling into nanocrystals. It was discovered that the atoms undergo a spontaneous transition between disordered and crystalline states.
'Be a man': Why some men respond aggressively to threats to manhood

When their manhood is threatened, some men respond more aggressively than others. New research suggests who may be most triggered by such threats - younger men whose sense of masculinity depends heavily on other people's opinions.
