How much is too much? It depends on how you say it – especially on a restaurant menu. Cornell University research reveals that descriptions of portion size impacts how much we eat and how much we’re willing to pay for our food.
The goal of restoring or creating wetlands on agricultural lands is almost always to remove nutrients and improve water quality. But new research shows that constructed marshes also excel at pulling carbon dioxide from the air and holding it long-term in soil, suggesting that farmers and landowners may also want to build wetlands to "farm" carbon.
Scientists led by a UCSF neurology researcher are reporting that they have identified the likely genetic mechanism that causes some patients with multiple sclerosis (MS) to quickly progress to a debilitating stage of the disease while other patients progress much more slowly.
Two new Baylor University studies show that Israeli Jewish adults who attend synagogue regularly, pray often, and consider themselves religious are significantly healthier and happier than their non-religious counterparts. They also report greater satisfaction with life.
A Kansas State University researcher finds that during the next 50 years, future generations of bison will be smaller in size and weigh less. Climate is likely to reduce the nutritional quality of grasses, causing the animals to grow more slowly.
Innovative machine learning technology developed by Columbia Engineering is the driving force—in effect, the brain—behind Di-BOSS™, a new digital building operating system that integrates all building operating systems into one, easy-to-use cockpit control interface for desktops and portable devices. The system has been successfully piloted in NYC by Rudin Management, saving them energy costs and resources.
This collision between a spiral galaxy and an elliptical galaxy resembles a celestial bird. The gravitational pull has stretched the spiral into an elongated shape. Lying 326 million light-years away, this colliding galaxy pair, known as Arp 142, is captured by NASA's Hubble Space Telescope.
One in four people who survive a stroke or transient ischemic attack (TIA) suffer from symptoms of PTSD within the 1st year post-event, and one in nine experience chronic PTSD more than a year later. The data, e-published by PLOS ONE, suggest that each year nearly 300,000 stroke/TIA survivors will develop PTSD symptoms as a result of their health scare.
Some parents desire for their children to fulfill their own unrealized ambitions, just as psychologists have long theorized, according to a new first-of-its-kind study.
The results of a new survey by the University of Massachusetts Amherst show that a majority of Americans across the political spectrum oppose the outsourcing of lethal military and defense targeting decisions to machines. The opposition to autonomous weaponry is bipartisan, with the strongest opposition on the far left and far right, and among active and former members of the military.
Nearly 70 percent of Americans are on at least one prescription drug, and more than half take two, Mayo Clinic and Olmsted Medical Center researchers say. Antibiotics, antidepressants and painkilling opioids are most commonly prescribed, their study found. Twenty percent of patients are on five or more prescription medications, according to the findings, published online in the journal Mayo Clinic Proceedings.
A team of Vanderbilt researchers has provided important validation of maps of the brain at rest that may offer insights into changes in the brain that occur in neurological and psychiatric disorders.
What common appliance was invented after an experiment with radar in 1945? The microwave oven. The first models were huge—about 6 feet in height and weighing more than 750 pounds. After World War II, when wartime technologies were adapted for domestic purposes, the ovens became smaller and more suitable for homes.

A new paper in PLOS Biology this week shows that taking the unusual step of including parasites in ecological datasets does alter the structure of resulting food webs, but that's mostly due to an increase in diversity and complexity rather than the particular characteristics of parasites. The work answers some longstanding questions about the unique role parasites play in ecological networks.
Astrophysicists using high-powered computer simulations demonstrate that gas spiraling toward a black hole inevitably results in X-ray emissions.
After laboring under other theories that never seemed to add up, McMaster University researchers have concluded that menopause is an unintended outcome of natural selection, generated by men's historical preference for younger mates.
E. coli that produce a toxin dangerous to humans may survive longer in water than benign counterparts, a new study finds.The findings have implications for water quality testing, suggesting that a lake's overall E. coli population may be a poor indicator of danger.
The keen vision of NASA's Hubble Space Telescope has detected a mysterious gap in a vast protoplanetary disk of gas and dust swirling around the nearby star TW Hydrae, located 176 light-years away in the constellation Hydra (the Sea Serpent). The gap's presence is best explained as due to the effects of a growing, unseen planet that is gravitationally sweeping up material and carving out a lane in the disk, like a snow plow.
