Early in the COVID-19 pandemic, old and young individuals did not differ in taking precautions, but over time, older people quickly adopted preventive behaviors and they engaged in more preventive behaviors. Older people engaged in fewer risky behaviors relative to younger people on month after the beginning of the pandemic and this age difference persisted over time; both young and older people started engaging in more potentially risky behaviors.
Certain parts of our body, such as the skin or liver, can repair themselves after a damage. Known as cell regeneration, this phenomenon describes how cells that are still functional start to proliferate to compensate for the loss. For the past 30 years, scientists have been investigating the regenerative potential of beta cells, pancreatic cells in charge of the production of insulin. Beta-cell population is indeed partially destroyed when diabetes occurs, and regenerating these cells represents an outstanding clinical challenge.
A new study from the USC Leonard Davis School of Gerontology shows that the behavioral responses to COVID-19 differed by age. The research, led by Jung Ki Kim, research associate professor at the USC Leonard Davis School, examined how age affected the practice of preventive and risky behaviors in response to COVID-19 and how these behaviors changed over the first three months of the pandemic.
The article was co-authored by University Professor Eileen Crimmins, holder of the AARP Chair in Gerontology, and appeared online in the journal PLOS One on November 10, 2020.
Arguably, almost all truly intriguing systems are ones that are far away from equilibrium -- such as stars, planetary atmospheres, and even digital circuits. But, until now, systems far from thermal equilibrium couldn't be analyzed with conventional thermodynamics and statistical physics.
On 29 October 2020, the US Fish and Wildlife Service (USFWS) announced the "successful recovery" of the US gray wolf population, with US Secretary of the Interior Secretary David Bernhardt stating that the species had "exceeded all conservation goals for recovery." These claims have been rebutted by numerous experts, who argue that the delisting decision is premature.
Yale researchers have discovered a protein that helps protect hosts from infection with the tick-borne spirochete that causes Lyme Disease, a finding that may help diagnose and treat this infection, they report Nov. 11 in the journal PLOS Pathogens.
Management scholars generally agree that being proactive at work yields positive outcomes. Studies show proactive -- as compared to reactive -- people tend to perform at higher levels.
Artificial intelligence is supposed to make machines perform at ever more amazing levels. A robot that can do little more than a remote-controlled model car has a limited range of applications. But from an automatic machine to an autonomous robot, it is a big, almost revolutionary step.
UNIVERSITY PARK, Pa. -- An implantable smart wrap that fits safely and securely around the bladder may one day help people who have under-active bladders, a condition that hinders patients from urinating regularly and comfortably, according to an international team of researchers.

1. Insights From Rapid Deployment of a "Virtual Hospital" as Standard Care During the COVID-19 Pandemic
"Age gates" that aim to keep underage users off alcohol websites are mostly ineffective, a Texas A&M University alcohol researcher found.
"Alcohol brand age gates are weak, at best, and likely an inconsequential barrier that someone with limited math abilities can easily overcome," said Adam Barry, a professor in the Department of Health and Kinesiology.
BIRMINGHAM, Ala. - University of Alabama at Birmingham researchers have discovered a previously undescribed population of neurons that help control our eyes as they view in three-dimensional space.
During normal viewing, we direct our eyes between objects in the three-dimensional space many times a minute. With each change, the left and right eyes will rotate, generally in the same direction, but mostly by different degrees of rotation. These unequal movements are known as disjunctive saccades.
Ever receive a vaccination that seemed to burn a lot while it was injected? The vaccine solution likely contained a lot of salt or sugar -- natural preservatives that help keep it stable, in addition to the cold temperature at which it was kept.
The viruses in vaccines, which train our cells to identify and vanquish viral invaders must be kept cold to keep them from bursting apart. The typical shipping temperature for vaccines ranges from 2 to 8 degrees Celsius (35 to 47 degrees Fahrenheit).
The effects of climate change are sometimes difficult to grasp, but now a virtual reality forest, created by geographers, can let people walk through a simulated forest of today and see what various futures may hold for the trees.
"The main problem that needs to be addressed is that climate change is abstract," said Alexander Klippel, professor of geography, Penn State. "Its meaning only unfolds in 10, 15 or 100 years. It is very hard for people to understand and plan and make decisions."
Scientists at Sanford Burnham Prebys Medical Discovery Institute, University of California San Diego School of Medicine and Hopp Children's Cancer Center Heidelberg (KiTZ) have demonstrated that personalized drug screens can be used to identify new therapeutic candidates for medulloblastoma, the most common malignant brain cancer in children.
