The purpose of this study was to determine the extent to which horticultural businesses were directly selling live plant products online, either through Amazon, Ebay, or from their own websites.

Researchers have discovered how to make 'superalloys' even more super, extending useful life by thousands of hours. The discovery could improve materials performance for electrical generators and nuclear reactors.

A newborn baby's brain responds to being touched on the face, according to new research. Babies use this sense of touch -- facial somatosensation -- to find and latch onto their mother's nipple, and should have this ability from birth. Premature babies often…

Color can impact the taste of food, and our experiences and expectations can affect how we taste food, according to Penn State researchers, who suggest this may have implications for how food and beverage industries should market their products.

Lowering mutation rates in harmful bacteria might be an as yet untried way to hinder the emergence of antimicrobial pathogens. One target for drug development might be a protein factor, DNA translocase Mfd, that enables bacteria to evolve rapidly by promoting…

For half a century, researchers have seen loops of displaced atoms appearing inside nuclear reactor steel after exposure to radiation, but no one could work out how.

A surprising discovery about a failed pain drug -- and specifically, the pathway it targets, BH4 -- could have implications for autoimmunity and cancer. Neuroscientists report that BH4 also functions as a kind of immunological thermostat, raising and lowering…

Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research has found evidence that sometimes the…

Study confirms biological mechanism responsible for latent HIV reservoirs; suggests strategies for a functional HIV cure.

Scientists suggest that being raised communally makes mice more competitive when they're older. It is well known that in many animals, including humans, early-life experiences have long-lasting effects on the development of behaviors later in life. Researchers…

Forests in the Pacific Northwest will be less vulnerable to drought and fire over the next three decades than those in the Rocky Mountains and Sierra Nevada, computer modeling shows.

While it is well known that physical activity is important for heart health, neither research nor recommendations consistently differentiate between the benefits of different types of physical activity. New research found that while all physical activity is…

Biologists reveal the hidden molecular basis of brain disorders and provide the first cell atlas of the hippocampus -- the part of the brain that helps regulate learning and memory -- as it is affected by traumatic brain injury. The researchers propose gene…

In a landmark decision, representatives from 60 countries voted to redefine the International System of Units (SI), changing the world's definition of the kilogram, the ampere, the kelvin and the mole, forever.

Currently, half of the world's measured precipitation that falls in a year falls in just 12 days, according to a new analysis of data collected at weather stations across the globe. By century's end, climate models project that this lopsided distribution of…

A single season of high school football may cause microscopic changes in the structure of the brain, according to a new study. A new type of magnetic resonance imaging (MRI) revealed significant changes in the structure of the grey matter in the front and rear…

A large study links social isolation with a higher risk of death from all causes combined and heart disease for all races studied, and with increased cancer mortality in white men and women.

How can a doctor predict the treatment outcome of an individual patient? Traditionally, the effectiveness of medical treatments is studied by randomized trials, but is this really the only reliable way to evaluate treatment effectiveness, or could something be…

Researchers found that the filamin A-Drp1 complex mediates mitochondrial fission in a mouse model of hypoxic heart cells. Results show that hypoxic stress brought about the interaction of filamin A with Drp1 and increased Drp1 activity in heart cells. This…

Scientists have found evidence that when projectiles hit soft clumps of dust or hard clumps of loose glass beads, the scaling laws for energy dissipation and energy transfer are the same in each case. This helps us understand how granular clumps stick…

A catalyst for carbon dioxide recycling, Mineral pentlandite may also be a conceivable alternative to expensive precious metal catalysts. Pentlandite had previously been known as a catalyst for hydrogen production. By adding a suitable solvent, the researchers…

The paleontological site of Somosaguas (Madrid) hosts a large colony of ants of the species Messor barbarus. A study has now revealed that the daily activity of these insects modifies soil composition and therefore influences the results obtained in…

Long term exposure to road traffic noise is associated with increased risk of obesity.

The time of day, determined by a cell's internal clock, has a stronger influence on cell division than previously thought, reveals a new study.

Population geneticists have found that eleven seal species only narrowly escaped extinction.

In optogenetics, researchers use light to control protein activity. This technique allows them to alter the shape of embryonic tissue and to inhibit the development of abnormalities. Now, scientists have enhanced the technique to stop organ-shaping processes…

Scientists elucidate the mechanism for the transport of water-insoluble protein molecules in mitochondria.

Researchers used ultrabright x-rays to generate 3D nanoscale maps of a single bacteria's chemical composition with unparalleled spatial resolution.

For the first time scientists have identified how to halt kidney disease in a life-limiting genetic condition, which may pave the way for personalised treatment in the future.

New research describes the behavioral and chemical strategies of a Florida ant, Formica archboldi, that decorates its nest with the dismembered body parts of other ant species.
