Researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) found that transitioning land enrolled in the Conservation Reserve Program (CRP) to bioenergy agriculture can be advantageous for American landowners, the government, and the environment.
Skoltech researchers have designed a software-based algorithm for synchronizing time across smartphones that can be used in practical tasks requiring simultaneous measurements. This algorithm can essentially help turn several devices into a full-fledged network of sensors. The paper was published in the journal Sensors.
Scientists at the University of Adelaide have challenged the common assumption that genetic diversity of a species is a key indicator of extinction risk.
Published in the journal PNAS, the scientists demonstrate that there is no simple relationship between genetic diversity and species survival. But, Dr Joao Teixeira and Dr Christian Huber from the University of Adelaide's School of Biological Sciences conclude, the focus shouldn't be on genetic diversity anyway, it should be on habitat protection.
Bright, coherent soft X-ray radiation (SXR) is used in many scientific applications such as advanced absorption spectroscopy or lens-less imaging, and in fundamental research e.g. to produce extremely short isolated optical pulses. Therefore, the generation, control, and detection of this type of short-wavelength light is highly important in fields like fundamental atomic physics, solid-state physics, the semiconductor industry, material science and biology.
DURHAM, N.C. -- Younger, smaller trees that comprise much of North America's eastern forests have increased their seed production under climate change, but older, larger trees that dominate forests in much of the West have been less responsive, a new Duke University-led study finds.
Declines in these trees' seed production, or fecundity, could limit western forests' ability to regenerate following the large-scale diebacks linked to rising temperatures and intensifying droughts that are now occurring in many states and provinces.
Using an innovative computational approach to analyze vast brain cell gene expression datasets, researchers at MIT and Sorbonne Université have found that Huntington's disease may progress to advanced stages more because of a degradation of the cells' health maintenance systems than because of increased damage from the disease pathology itself.
A new study has for the first time explored the rate at which the world's largest fish, the endangered whale shark, can recover from its injuries. The findings reveal that lacerations and abrasions, increasingly caused through collisions with boats, can heal in a matter of weeks and researchers found evidence of partially removed dorsal fins re-growing.
X-ray scans revolutionised medical treatments by allowing us to see inside humans without surgery. Similarly, terahertz spectroscopy penetrates graphene films allowing scientists to make detailed maps of their electrical quality, without damaging or contaminating the material. The Graphene Flagship brought together researchers from academia and industry to develop and mature this analytical technique, and now a novel measurement tool for graphene characterisation is ready.
Seasons have an impact on our emotions and social life. Negative emotions are more subdued in the summer, whereas seasonal affective disorder rates peak during the darker winter months. Opioids regulate both mood and sociability in the brain.
In the study conducted at the Turku PET Centre, Finland, researchers compared how the length of daylight hours affected the opioid receptors in humans and rats.
Researchers have called on European policymakers to make adequate resources available to tackle pancreatic cancer, a disease that is almost invariably fatal and where little progress has been made over the past 40 years.
Home gardens are by far the biggest source of food for pollinating insects, including bees and wasps, in cities and towns, according to new research.
The study, led by the University of Bristol and published today in the Journal of Ecology, measured for the first time how much nectar is produced in urban areas and discovered residential gardens accounted for the vast majority - some 85 per cent on average.
Some microbes on Earth could temporarily survive on the surface of Mars, finds a new study by NASA and German Aerospace Center scientists. The researchers tested the endurance of microorganisms to Martian conditions by launching them into the Earth's stratosphere, as it closely represents key conditions on the Red Planet.
Results from a large prospective study indicate that gastroesophageal reflux disease (GERD), which also causes heartburn symptoms, is linked with higher risks of various cancers of the larynx (or voice box) and esophagus. The study is published early online in CANCER, a peer-reviewed journal of the American Cancer Society.
The El Niño-Southern Oscillation (ENSO) is the most energetic naturally occurring year-to-year variation of ocean temperature and rainfall on our planet. The irregular swings between warm and wet "El Niño" conditions in the equatorial Pacific and the cold and dry "La Niña" state influence weather conditions worldwide, with impacts on ecosystems, agriculture and economies.
VANCOUVER, Wash. - Loss of biodiversity in the face of climate change is a growing worldwide concern. Another major factor driving the loss of biodiversity is the establishment of invasive species, which often displace native species. A new study shows that species can adapt rapidly to an invader and that this evolutionary change can affect how they deal with a stressful climate.
