― Cash hoarding nothing new for businesses, scholar says
[physorg.com]
The U.S. economy is experiencing anemic growth, yet businesses are sitting on a mountain of cash worth nearly $2 trillion, according to Federal Reserve estimates. But this trend is nothing new for firms, who have been steadily increasing their cash holdings over the past three decades, a University of Illinois business professor says.
― Why the biological clock? Study says aging reduces centromere cohesion, disrupts reproduction
[physorg.com]
University of Pennsylvania biologists studying human reproduction have identified what is likely the major contributing factor to the maternal age-associated increase in aneuploidy, the term for an abnormal number of chromosomes during reproductive cell division.
― Early warning for close approaches of two house-sized asteroids
[planetary.org]
Most of you have probably heard by now of two small asteroids, both in the neighborhood of 10 meters in diameter, recently discovered on trajectories that pass unusually close to Earth. They were discovered on September 5 by the Catalina Sky Survey, and have since been observed by numerous amateur and professional astronomers. Neither poses any risk to Earth; even if they were on collision courses, which they are not, they would be too small ....
― Researchers identify potential new drug for neurodegenerative disease
[physorg.com]
Scientists have discovered a small molecule that helps human cells get rid of the misfolded, disfigured proteins implicated in Alzheimer's disease and other neurodegenerative ailments. This potential drug could have applications for other conditions as well.
― Unauthorized population would soar if birthright citizenship repealed

Repeal of birthright citizenship for the U.S.-born children of unauthorized immigrants would expand the nation's unauthorized population by at least 5 million over the next decade, according to a new report from the Migration Policy Institute.
― Researchers hear puzzling new physics from graphene quartet's quantum harmonies
[physorg.com]
Using a one-of-a-kind instrument designed and built at the National Institute of Standards and Technology, an international team of researchers have "unveiled" a quartet of graphene's electron states and discovered that electrons in graphene can split up into an unexpected and tantalizing set of energy levels when exposed to extremely low temperatures and extremely high magnetic fields.
― Satellite data reveal seasonal pollution changes over India

Armed with a decade's worth of satellite data, University of Illinois atmospheric scientists have documented some surprising trends in aerosol pollution concentration, distribution and composition over the Indian subcontinent.
― Study adds new clue to how last ice age ended
[physorg.com]
As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winters in the north, Antarctica was heating up. For the two decades since ice core records revealed that Europe was cooling at the same time Antarctica was warming over this thousand-year period, scientists have looked for an explanation.
― Scientists identify molecular gatekeeper of arthritis

Elimination of a molecular gatekeeper leads to the development of arthritis in mice, scientists report in a study published in the Journal of Experimental Medicine. The newly discovered gatekeeper is a protein that determines the fate - survival or death - of damaging cells that mistakenly attack the body's own tissues and lead to autoimmune disorders such as arthritis.
Stanford University researchers have developed a revolutionary, non-invasive way of quickly predicting the future health of premature infants, an innovation that could better target specialized medical intervention and reduce health-care costs.
