A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of our solar system blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not to blame--the sun's magnetism is.
July 2, 2021 - For health care organizations looking to improve performance and patient experiences, implementing data-driven solutions can be effective when focusing on addressing health equity and reducing patient length of stay.
GAINESVILLE, Fla. --- Archaeologists have unearthed a rare trove of more than 80 metal objects in Mississippi thought to be from Hernando de Soto's 16th-century expedition through the Southeast. Many of the objects were repurposed by the resident Chickasaws as household tools and ornaments, an unusual practice at a time when European goods in North America were few and often reserved for leaders.
MANHATTAN, KANSAS -- A recent study by Kansas State University virologists demonstrates successful postinfection treatment for SARS-CoV-2, the virus that causes COVID-19.
College of Veterinary Medicine researchers Yunjeong Kim and Kyeong-Ok "KC" Chang published the study in the prestigious journal Proceedings of the National Academy of Sciences of the United States of America, or PNAS. They found that animal models infected with SARS-CoV-2 and treated with a deuterated protease inhibitor had significantly increased survival and decreased lung viral load.
It is the membrane of cancer cells that is at the focus of the new research now showing a completely new way in which cancer cells can repair the damage that can otherwise kill them.
In both normal cells and cancer cells, the cell membrane acts as the skin of the cells. And damage to the membrane can be life threatening. The interior of cells is fluid, and if a hole is made in the membrane, the cell simply floats out and dies - a bit like a hole in a water balloon.
(Boston)--Would you be more willing to get vaccinated against the COVID-19 virus if you could participate in a lottery for cash and prizes? The answer was surprisingly no, according to Boston University School of Medicine (BUSM) researchers who found that Ohio's "Vax-a-Million" lottery-based incentive system, intended to increase COVID-19 vaccination rates, was not associated with an increase in COVD-19 vaccinations.
Some three quarters of the biomass in hop plants used in beer-making ends up in landfills. But a group of Japanese researchers has developed a technique that 'upcycles' that waste hop into cellulose nanofibers (CNFs). A paper describing the technique was published in the journal ACS Agricultural Science & Technology on June 11.
Wander around a desert most anywhere in the world, and eventually you'll notice dark-stained rocks, especially where the sun shines most brightly and water trickles down or dew gathers. In some spots, if you're lucky, you might stumble upon ancient art - petroglyphs - carved into the stain. For years, however, researchers have understood more about the petroglyphs than the mysterious dark stain, called rock varnish, in which they were drawn.
In particular, science has yet to come to a conclusion about where rock varnish, which is unusually rich in manganese, comes from.
BOSTON -- Gaurav Gaiha, MD, DPhil, a member of the Ragon Institute of MGH, MIT and Harvard, studies HIV, one of the fastest-mutating viruses known to humankind. But HIV's ability to mutate isn't unique among RNA viruses -- most viruses develop mutations, or changes in their genetic code, over time. If a virus is disease-causing, the right mutation can allow the virus to escape the immune response by changing the viral pieces the immune system uses to recognize the virus as a threat, pieces scientists call epitopes.
NDIANAPOLIS--Indiana University School of Medicine researchers are developing a new, noninvasive brain stimulation technique to treat neurological disorders, including pain, traumatic brain injury (TBI), epilepsy, Parkinson's disease, Alzheimer's disease and more.
"Given the increasing use of brain stimulation in human brain study and treatment of neurological diseases, this research can make a big impact on physicians and their patients," said Xiaoming Jin, PhD, associate professor of anatomy, cell biology and physiology.
Ibaraki, Japan - The flavor of a tomato is an interaction between its taste and aroma. Now, researchers from Japan and the United States have revealed that the pigments that determine the colors of tomatoes also affect their flavor.
In a study published this month, researchers from University of Tsukuba developed a new method to rapidly measure the pigment profiles of tomatoes and used the technique to explore how pigments affect the taste and aroma of different tomato varieties.
What The Study Did: Researchers estimated the frequency and magnitude of surprise bills for deliveries and newborn hospitalizations, which are the leading reasons for hospitalization in the United States, to illustrate the potential benefits of federal legislation that will protect families from most surprise bills. Potential surprise bills were defined as claims from out-of-network clinicians and ancillary service providers, such as an ambulance.

PHILADELPHIA-- While more women are entering the field of academic medicine than ever before, they are less likely to be recognized as experts and leaders; they are less likely to receive prestigious awards, be promoted to full professorships,
The human brain is a wonderfully enigmatic organ, helping to juggle multiple tasks efficiently to help us get through a long day! This feature, called executive function, seats primates like us at the pinnacle of evolution. The prospect of losing the spectacular flow of neural information in our brains because of an accident or disease is, thus, unnerving.
Guadalupe fur seals (Arctocephalus townsendi) have established a large resting colony in the Gulf of California--bringing the total number of sites where this endangered species now occurs to just four. This new haul-out was discovered on El Farallón de San Ignacio Island, along the mainland coast of Mexico, according to researchers from Mexico and the University of British Columbia.
