The massive ice sheet covering Greenland may have melted by a record amount this year, scientists say.
Selective browsing by white-tailed deer has been blamed by many for changing the character and composition of forest understories in the eastern US; however, its impact on the forest canopy was previously unknown.
A new study links changes in the gene for the protein focal adhesion kinase, or FAK, to ovarian cancer's ability to survive chemotherapy.
Scientists have found evidence suggesting that resistance to the 'hunger hormone' ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer's disease (AD). The findings, based on observations of postmortem brain-tissue samples from Alzheimer's patients and on experiments with a mouse model of AD, also suggest a possible treatment strategy for the...
With warming temperatures, average snowfall frequency is estimated to decline across the Pacific Northwest by 2100 -- and at a faster rate if greenhouse emissions are not reduced, according to a new study.
Available to some Facebook users since December 2017, face recognition notifies an account holder if their profile photo is used by someone else or if they appear in photos where they have not been...

Why didn’t a traffic-light scheme stop the recent fracking-induced tremors near Blackpool?In theory, the chances of your house being shaken by a fracking-related earthquake are incredibly slim. In the UK, a traffic-light system is designed to minimise the risk of larger quakes occurring, with fracking halted if a tremor of magnitude 0.5ML (local magnitude) or above is recorded. So last week’s...
A new study looking at incidence of disease data nationwide from 2000 to 2016 found a shift in obesity-associated cancers (OACs) to younger individuals. Typically, these cancers are diagnosed at higher rates among people older than 65. The most notable findings pertain to increases in these OACs among non-Hispanic Black and Hispanic women and men for whom certain cancers increased by 200-400%.
Researchers offer new insight into the evolution of the suction ability of remora fishes, showcasing a bioinspired suction disk that mimics, and can exceed, the fish's uncanny powers of adhesion.
After devastating the Bahamas, Dorian is continuing its long crawl toward the southeast US with slightly weakened winds. Hurricane Dorian stormed into the record books on Sunday when its maximum sustained winds of 185 miles (300 kilometers) per hour tied it in second place with 1998's Gilbert and 2005's Wilma as the most powerful Atlantic hurricane since 1950, according to Colorado State...
Scientists have discovered that a receptor on the surface of brain cells plays a key role in regulating how both animals and people respond to stress. The research suggests that the receptor may represent an important biomarker of post-traumatic stress disorder (PTSD) in humans and may offer a new target for future, more effective treatments for stress and anxiety.
States that require prescribers to register with and use prescription drug monitoring programs in most clinical circumstances saw notably fewer opioid prescriptions and reduced opioid-related hospital use by Medicaid patients compared to states with weak or no drug monitoring program mandates, according to a new study.
E*TRADE Financial Corporation today released the data from its monthly sector rotation study, based on the E*TRADE customer net percentage buy/sell behavior for stocks that comprise the S&P 500...

With warming temperatures, average snowfall frequency is estimated to decline across the Pacific Northwest by 2100—and at a faster rate if greenhouse emissions are not reduced, according to a new Portland State University study.
All parents want their children to get the best education possible, so how do school districts allow parents/guardians to have a say in where their child goes to school while still meeting diversity goals for the student body? New research in an upcoming addition of the INFORMS journal Operations Research has a solution, just in time for children to return to school for the 2019-2020 year.
Researchers from Texas A&M University published new research in the INFORMS journal Marketing Science, which shows that retailers' branded mobile apps are very effective in increasing customer engagement, increasing sales on multiple levels, not just on the retailer's website, but also in its stores. At the same time, apps increase the rate of returns, although the increase in sales outweighs the...
Another Atlantic Ocean basin depression formed while Hurricane Dorian is still wreaking havoc on the Bahamas and affecting the southeastern U.S. Infrared imagery from NASA's Aqua satellite shows that Tropical Depression 7 in the western Gulf of Mexico has developed powerful thunderstorms with heavy rain capabilities. That potential for heavy rainfall includes southern Texas and northeastern...
NASA's Aqua satellite passed over the Eastern Pacific Ocean and provided an image of Hurricane Juliette as its eye began to emerge. Juliette has grown into a major hurricane, about 450 miles southwest of the southern tip of Baja California, Mexico.
In the early hours of Tuesday, September 3, Hurricane Dorian had been stationary over the island of Grand Bahama for 18 hours, most of the time as a category 5 hurricane. Storm-total rain accumulation over parts of Grand Bahama and Abaco Islands have exceeded 24 inches according to NASA satellite-based estimates.
Pity the poor blemished banana. In a society that equates beauty with quality, the perception that blemished produce is less desirable than its perfect peers contributes to 1.3 billion tons of wasted food a year globally.
An explosion is a complex event involving quickly changing temperatures, pressures and chemical concentrations. In a paper in the Journal of Applied Physics a special type of infrared laser, known as a swept-wavelength external cavity quantum cascade laser (swept-ECQCL), is used to study explosions. This versatile instrument has a broad wavelength tuning range that allows the measurement of...
The utterances of Old World monkeys, some of our primate cousins, may be more sophisticated than previously realized—but even so, they display constraints that reinforce the singularity of human language, according to a new study co-authored by an MIT linguist.
In the case of Alzheimer's disease, researchers show that mitochondrial calcium transport remodeling -- what appears to be an attempt by cells to compensate for flagging energy production and metabolic dysfunction -- while initially beneficial, ultimately becomes maladaptive, fueling declines in mitochondrial function, memory, and learning. The new research, published by Nature Communications, is...
In a society that equates beauty with quality, the perception that blemished produce is less desirable than its perfect peers contributes to 1.3 billion tons of wasted food a year globally. Researchers are suggesting a potential solution -- they found that 'humanizing' produce can change consumer attitudes toward fresh fruits and vegetables that are showing signs of age.
An explosion is a complex event involving quickly changing temperatures, pressures and chemical concentrations. A special type of infrared laser, known as a swept-wavelength external cavity quantum cascade laser, can be used to study explosions. This versatile instrument has a broad wavelength tuning range that allows the measurement of multiple chemical substances in an explosive fireball. The...
Hurricane Dorian is finally moving. Before Dorian picked up speed Tuesday morning, the upper atmosphere had been too calm. Its eyewall first hit Grand Bahama Island Sunday night, and into Tuesday morning part of the eye still lingered there, meteorologists...
Using anti-bacterial mouthwash could reduce the benefits of exercise, a study has found. Physical exertion is known to lower blood pressure but the effects are significantly reduced when people use mouthwash instead of water. A team of international scientists said the results showed the importance of oral bacteria in cardiovascular health. They are urging health professionals to pay attention to...
