Island channel could power about half of Scotland, studies show
Renewable tidal energy sufficient to power about half of Scotland could be harnessed from a single stretch of water off the north coast of the country, engineers say.

New hope for Gaucher patients
Weizmann Institute scientists have discovered a new cellular pathway implicated in Gaucher disease.

The water cycle amplifies abrupt climate change
During the abrupt cooling at the onset of the so-called Younger Dryas period 12680 years ago changes in the water cycle were the main drivers of widespread environmental change in western Europe.

Decoded: DNA of blood-sucking worm that infects world's poor
Researchers at Washington University School of Medicine in St. Louis have decoded the genome of the hookworm, Necator americanus, finding clues to how it infects and survives in humans and to aid in development of new therapies to combat hookworm disease.

Melatonin may lower prostate cancer risk
Higher levels of melatonin, a hormone involved in the sleep-wake cycle, may suggest decreased risk for developing advanced prostate cancer, according to results presented here at the AACR-Prostate Cancer Foundation Conference on Advances in Prostate Cancer Research, held Jan.

Keeping whales safe in sound
The International Union for the Conservation of Nature is intensifying global efforts to safeguard whales and other marine species from the harms of powerful noise used in seismic seafloor surveys by the oil and gas industry and others.

Understanding the functioning of a new type of solar cell
EPFL scientists have uncovered the mechanism by which novel, revolutionary solar cells based on lead iodide perovskite light-absorbing semiconductor transfer electrons along their surface.

Ingredients in chocolate, tea and berries could guard against diabetes
Eating high levels of flavonoids including anthocyanins and other compounds (found in berries, tea, and chocolate) could offer protection from type 2 diabetes -- according to research from the University of East Anglia and King's College London.

Researchers identify possible explanation for link between exercise & improved prostate cancer outcomes
Men who walked at a fast pace prior to a prostate cancer diagnosis had more regularly shaped blood vessels in their prostate tumors compared with men who walked slowly, providing a potential explanation for why exercise is linked to improved outcomes for men with prostate cancer, according to results presented here at the AACR-Prostate Cancer Foundation Conference on Advances in Prostate Cancer Research, held Jan.

Distant quasar illuminates a filament of the cosmic web
Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing for the first time part of the network of filaments thought to connect galaxies in a cosmic web.

Health in the Arab world
On 20 January 2014, The Lancet will publish a series of papers on Health in the Arab World: a view from within.

Cleveland Clinic identifies mechanism in Alzheimer's-related memory loss
Cleveland Clinic researchers have identified a protein in the brain that plays a critical role in the memory loss seen in Alzheimer's patients, according to a study to be published in the journal Nature Neuroscience and posted online today.

How a versatile gut bacterium helps us get our daily dietary fiber
University of British Columbia researchers have discovered the genetic machinery that turns a common gut bacterium into the Swiss Army knife of the digestive tract -- helping us metabolize a main component of dietary fiber from the cell walls of fruits and vegetables.

Get used to heat waves: Extreme El Nino events to double
Extreme weather events fuelled by unusually strong El Ninos, such as the 1983 heatwave that led to the Ash Wednesday bushfires in Australia, are likely to double in number as our planet warms.

Milky Way may have formed 'inside-out': Gaia provides new insight into Galactic evolution
Research on first data release from Gaia-ESO project suggests the Milky Way formed by expanding out from the centre, and reveals new insights into the way our Galaxy was assembled.

York scientists investigate the fiber of our being
Research at the University of York's Structural Biology Laboratory, in collaboration with groups in Canada, the USA and Sweden, has begun to uncover how our gut bacteria metabolize the complex dietary carbohydrates found in fruits and vegetables.

Exposure to pesticides results in smaller worker bees
Exposure to a widely used pesticide causes worker bumblebees to grow less and then hatch out at a smaller size, according to a new study by Royal Holloway University of London.

Researchers discover how heart arrhythmia occurs
Researchers have discovered the fundamental biology of calcium waves in relation to heart arrhythmias.

Solar-power device would use heat to enhance efficiency
New approach developed at MIT could generate power from sunlight efficiently and on demand.
