Blood draws are no fun.They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too.Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19, or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and sepsis.
There isn't much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka's Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years.
Obamacare will get retooled, not repealed. A national mask mandate will boost consumer spending, research shows (though don't expect much from homeowners, they're strapped). The $300 billion for R&D should go to D, not R. So forecasts an array of WashU experts.
Researchers at Washington University School of Medicine in St. Louis have found that patients with Barrett's esophagus may be vulnerable to coronavirus infection from what they swallow.
Scientists at Washington University School of Medicine in St. Louis have shown that a relatively simple and rapid blood test can predict which patients with COVID-19 are at highest risk of severe complications or death. The blood test measures levels of mitochondrial DNA, which normally resides inside the energy factories of cells. Mitochondrial DNA spilling out of cells and into the bloodstream is a sign that a particular type of violent cell death is taking place in the body.
New research from Washington University School of Medicine in St. Louis indicates that allergens in the environment often are to blame for episodes of acute itch in eczema patients, and that the itching often doesn’t respond to antihistamines because the itch signals are being carried to the brain along a previously unrecognized pathway that current drugs don’t target.
Physicists at Washington University in St. Louis have discovered how to locally add electrical charge to an atomically thin graphene device by layering flakes of another thin material, alpha-RuCl3, on top of it. A paper published with scientists at Boston College describes the charge transfer process in detail. Gaining control of the flow of electrical current through atomically thin materials is important to potential future applications in photovoltaics or computing.
As Donald Trump prepares to leave the presidency Jan. 20 in the wake of being accused of fomenting the riot at the U.S. Capitol, he is reportedly considering an unprecedented move: a self-pardon.While no president has ever pardoned himself, the act might be more trouble than it’s worth for Trump, notes a criminal law and Supreme Court expert at Washington University in St.
In light of the Jan. 6 mob attack on the U.S. Capitol building, many Democrats, and even some Republicans, have called for the use of the 25th Amendment of the U.S. Constitution to relieve President Trump of his duties.What is that amendment and how does it work?Greg Magarian, the Thomas and Karole Green Professor of Law and Constitutional law expert at Washington University in St.
The Democrats’ dual victories in Georgia’s runoff election on Jan. 5, created a rare 50-50 split in the U.S. Senate and will give majority power to the Democrats once Vice President-elect Kamala Harris — potentially, the deciding vote — is sworn into office on Jan. 20.Given how divided politics in America has become, will the tied Senate be in constant gridlock?Not necessarily.

As part of the new $900 billion federal stimulus package, the moratorium on evictions for renters will be extended by one month, through the end of January. The help could not come soon enough, said an expert on social and economic development at the Brown School at Washington University in St. Louis.However, without more intentional, long-term solutions and investments, this aid will only postpone an inevitable housing crisis, she said a new survey shows.
After months of failed negotiations that left many Americans, businesses and a further weakening economy in the lurch, lawmakers are scrambling the week before Christmas 2020 to reach a deal on an economic stimulus plan that could top $900 billion. If Congress passes the deal, will it do enough to help struggling Americans and businesses stay afloat?To answer that question, three business and economics experts at Washington University in St.
But sometimes ribosomes get stuck or stall on roadblocks along defective mRNA molecules. New research from Washington University in St. Louis shows that cells monitor for ribosome collisions to determine the severity of the problem and how best to respond when things start to go awry.
People with Alzheimer’s disease often have circadian rhythm problems. Researchers at Washington University School of Medicine in St. Louis have discovered a protein that is both regulated by clock genes and involved in clearing away Alzheimer’s protein build-up in the brain. The protein, YKL-40, could provide a new target for Alzheimer’s therapies.
Almost a year ago, COVID-19 began its global rampage, going on to infect about 69.5 million people and kill about 1.6 million as of early this month. From the beginning, most scientists have said that COVID-19 is deadlier than the seasonal flu, while fringe theories have circulated widely, suggesting it is less deadly or flu’s equal. Evidence is accumulating, however, to show just how much deadlier COVID-19 is compared with the flu and the extent of complications related to the two illnesses.
Thinking like Earthlings may have caused scientists to overlook the electrochemical effects of Martian dust storms. On Earth, dust particles are viewed mainly in terms of their physical effects, like erosion. But, in exotic locales from Mars to Venus to Jupiter's icy moon Europa, electrical effects can affect the chemical composition of a planetary body's surface and atmosphere in a relatively short time, according to research from Washington University in St. Louis.
