Wealthier northeastern US states and Western European countries tended to have significantly lower mortality rates during second-wave COVID-19 infections, new research from the University of Sydney and Tsinghua University has shown. However, the pattern was not as general as expected, with notable exceptions to this trend in Sweden and Germany.
Researchers say mortality change could have several explanations:
European first-wave case counts were underestimated;
First-wave deaths disproportionately affected the elderly;
WASHINGTON, March 16, 2021 -- Cancerous cells exhibit several key differences from healthy cells that help identify them as dangerous. For instance, the pH -- the level of acidity -- within a cancerous cell is not the same as the pH within a healthy cell.
Researchers from the National University of Singapore developed a method of using machine learning to determine whether a single cell is cancerous by detecting its pH. They describe their work in the journal APL Bioengineering, from AIP Publishing.
What The Study Did: The findings of this study suggest that, based on a sample from an otherwise healthy population, the overall number of SARS-CoV-2 infections in the U.S. may be substantially higher than estimates based on public health case reporting.
Authors: Robert L. Stout, Ph.D., of Clinical Reference Laboratory Inc. in Lenexa, Kansas, is the corresponding author.

16th of March, Tuesday, 2021 -- Longevity medicine is a rapidly evolving branch of preventative precision medicine that is specifically focused on promoting healthspan and lifespan, utilizing aging biomarkers commonly referred to as aging clocks. Over the past decade advances in AI and machine learning enabled the development of deep aging clocks (DACs) and other novel tools to track the rate of aging. In parallel novel preventative and therapeutic interventions have been discovered or progressed into clinical trials.
Global drylands are experiencing faster-than-average warming and are also among the most vulnerable regions to climate change. Meteorological metrics all point to an emerging trend of increased surface aridity, raising concerns of land desertification and degradation. However, recent satellite observations also show lusher drylands, in apparent contradiction to the image of drylands becoming drier.
New findings on the diet of Arctic foxes, determined by the condition of their teeth, show how varying climate conditions in the Arctic affect the animals that live there.
In a study published in Polar Biology, Peter Ungar, Distinguished Professor of anthropology at the University of Arkansas, and several co-authors analyzed tooth breakage and wear - both gross and micro - of Arctic foxes from Russia's Yamal Peninsula.
The Three Gorges project, completed in 2009, is one of the world's largest hydropower projects. It has brought important social and economic benefits in flood control, power generation, shipping and water resources redistribution.
Following a relocation of ice cores to the Copenhagen suburb of Rødovre in 2017, University of Copenhagen researchers found unopened boxes of ice cores dating back to 1966--the first ice cores drilled on Earth.
Analyses of the long-forgotten ice have now been completed and are presented in a new study with groundbreaking results.
Within the cores, which come from deep within the ice sheet at Camp Century, Greenland, the UCPH researchers and their Belgian and American colleagues became the first ever to find these millions of years old macrofossils.
BUFFALO, N.Y. - Nearly every older adult was prescribed a prescription drug that increased their risk of falling in 2017, according to new University at Buffalo research.
The study found that the percentage of adults 65 and older who were prescribed a fall- risk-increasing drug climbed to 94% in 2017, a significant leap from 57% in 1999. The research also revealed that the rate of death caused by falls in older adults more than doubled during the same time period.
SAN ANTONIO -- March 16, 2021 -- One of the most profound discoveries in planetary science over the past 25 years is that worlds with oceans beneath layers of rock and ice are common in our solar system. Such worlds include the icy satellites of the giant planets, like Europa, Titan and Enceladus, and distant planets like Pluto.
Researchers from Tokyo Medical and Dental University (TMDU) uncover potential novel therapeutic strategies for oral and esophageal carcinomas
Birds breathe with greater efficiency than humans due to the structure of their lungs--looped airways that facilitate air flows that go in one direction--a team of researchers has found through a series of lab experiments and simulations.
The findings will appear Fri., March 19 in the journal Physical Review Letters (to be posted between 10 and 11 a.m. EDT).
The study, conducted by researchers at New York University and the New Jersey Institute of Technology, also points to smarter ways to pump fluids and control flows in applications such as respiratory ventilators.
When rain began falling in northern Georgia on Sept. 15, 2009, little did Atlantans know that they would bear witness to epic flooding throughout the city. Neighborhoods, like Peachtree Hills, were submerged; Georgia's busiest expressway was underwater, as were roads and bridges; untreated sewage mingled with rising flood waters; cars and people were swept away. Then-Georgia-governor, Sonny Perdue, declared a state of emergency.
A new concept of on-demand drug delivery system has emerged in which the drugs are automatically released from in vivo medical devices simply by shining light on the skin.
In the brain, billions of neurons reach to each other, exchanging information, storing memories, reacting to danger and more. Scientists have barely scratched the surface of the most complex organ, but a new device to automatically collect tissue for analysis may allow for a quicker, deeper dive into the brain.
Their approach was published in IEEE/CAA Journal of Automatica Sinica, a joint publication of the IEEE and the Chinese Association of Automation.
