A study led by the Universitat Autònoma de Barcelona (UAB) reconstructs the entire trophic chain of a prehistoric site in Western Europe with samples from this Bronze Age settlement located in the southeast of the Iberian Peninsula.
The economy of La Bastida would have been more productive than other Argaric sites due to their fields being fertilised regularly by the grazing of livestock, which would have favoured a prominent development within the Argaric communities.
Preventing the death of neurons during brain growth means these 'zombie' cells can develop into functioning neurons, according to research in fruit flies from the Crick, the University of Lausanne (UNIL) and the Max Planck Institute for Chemical Ecology.
During brain development, a large number of neurons destroy themselves as part of an essential regulatory mechanism that removes excess cells. In certain areas of the human brain, this cellular "suicide", which is called apoptosis, affects about 50% of neurons.
The popular painkiller ibuprofen may have more significant effects on the liver than previously thought, according to new research from the University of California, Davis. The study in laboratory mice also shows marked differences between males and females.
The work is published Feb. 25 in Scientific Reports.
CLEMSON, South Carolina - Just as there is a mysterious dark matter that accounts for 85 percent of our universe, there is a "dark" portion of the human genome that has perplexed scientists for decades. A study published March 9, 2020, in Genome Research identifies new portions of the fruit fly genome that, until now, have been hidden in these dark, silent areas.
ITHACA, N.Y. - A new two-step technique to repair herniated discs uses hyaluronic acid gel to re-inflate the disc and collagen gel to seal the hole, essentially repairing ruptured discs like you'd repair a flat tire.
After a rupture, a jelly-like material leaks out of a herniated disc, causing inflammation and pain. The injury is usually treated one of two ways: a surgeon sews up the hole, leaving the disc deflated; or the disc is refilled with a replacement material, which doesn't prevent repeat leakages. Each approach on its own isn't always effective.
In a new peer-reviewed publication, University of Illinois at Chicago researchers describe how the body's response to inflammation, which helps to fight many kinds of infections, also can counterproductively suppress much-needed cell repair and regeneration in blood vessels.
EVANSTON, Ill. -- Every year, 15 million babies are born too early, with 1 million never making it to their next birthday. And in low-resource settings, the outlook is even more dire. Half of babies born at 32 weeks or earlier will die; whereas in high-resource settings, almost all of these babies survive.
To help bridge this gap, an interdisciplinary team of Northwestern University researchers has developed a new wireless, battery-charged, affordable monitoring system for newborn babies that can easily be implemented to provide clinical-grade care in nearly any setting.
What The Study Did: Researchers used French electronic health data to investigate how risk of colorectal cancer compared among obese adults who had weight-loss surgery and who didn't.

The ability of crocodiles to survive mass extinctions could be in part due to their more hands-on approach to parenting, say scientists at the University of Bath's Milner Centre for Evolution.
Crocodiles are one of the oldest surviving lineages on Earth, having survived two extinctions - the mass extinction in the late Cretaceous period that killed the dinosaurs 66 million years ago, and another smaller extinction event in the Eocene period 33.9 million years ago that wiped out huge numbers of marine and other aquatic life.
City dwellers take more antibiotics than people in rural areas; children and the elderly use them more often than middle-aged people; the use of antibiotics decreases as education increases, but only in rich countries: These are three of the more striking trends identified by researchers of the NRW Forschungskolleg "One Health and Urban Transformation" at the University of Bonn in a recent study. They evaluated 73 publications on the use of antibiotics in the outpatient sector around the world. The subject is of great importance: Too many antibiotics are still being administered.
For connoisseurs of wines and spirits, part of the enjoyment is noting the various flavors and scents that are revealed with each sip. Aging transforms alcohol's aroma further, especially in cognac, a type of twice-distilled fortified wine. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have identified a few compounds not previously known to contribute to an aged cognac's complex aroma.
It's one of the biggest economic changes in recent decades: Workers get a smaller slice of company revenue, while a larger share is paid to capital owners and distributed as profits. Or, as economists like to say, there has been a fall in labor's share of gross domestic product, or GDP.
Updated guidelines for exposure to high-frequency electromagnetic fields published in Health Physics
March 11 , 2020 - A set of updated, evidence-based guidelines defining safe levels of exposure to high-frequency electromagnetic fields (EMF) has been published in Health Physics, official journal of the Health Physics Society.
CHAPEL HILL, NC - March 11, 2020 - People with multiple sclerosis (MS) often have a greatly increased risk of falling and injuring themselves even when they feel they're able to walk normally. Now a team led by scientists from the UNC School of Medicine has demonstrated what could be a relatively easy method for the early detection of such problems.
BINGHAMTON, N.Y. - Older children respond more strongly to rewarding experiences and less strongly to negative experiences later in the day, which may lead to poor decision-making at night, according to research from Binghamton University, State University of New York.
