The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers have detected a stream of stars in one of the Andromeda Galaxy's outer satellite galaxies, a dwarf galaxy called Andromeda II. This galaxy is very small -- less than one percent of the Milky Way. The movement of...

Researchers have discovered the presence of a novel subtype of innate lymphoid cells in human spleen essential for the production of antibodies. This discovery clears the path to the identification of novel strategies to develop more efficient vaccines against encapsulated bacteria, considered...

Scientists studying the sexual transformation of the malaria parasite have solved a long-standing mystery in parasite biology. Two research teams have independently discovered that a single protein acts as the master genetic switch that triggers the development of male and female sexual forms of...

Científicos del Instituto Hospital del Mar de Investigaciones Médicas han descrito un nuevo subtipo de células linfoides innatas esenciales para la producción de anticuerpos, un hallazgo que puede desembocar en el desarrollo de vacunas más eficaces contra las bacterias encapsuladas....

The key characteristics of birds which allow them to fly -- their wings and their small size -- arose much earlier than previously thought, according to new research from the Universities of Bristol and Sheffield into the Paraves, the first birds and their closest dinosaurian relatives which lived...

The United Kingdom urgently needs a green economic strategy to move towards low-carbon prosperity, resource security and environmental quality, says a new report published today by University College London's Green Economy Policy Commission. Fuente :...

Scientists at the Gladstone Institutes and the University of California, San Francisco, have made an important breakthrough: they have discovered a way to transform skin cells into mature, fully functioning liver cells that flourish on their own, even after being transplanted into laboratory...

With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus. Fuente : http://www.eurekalert.org/pub_releases/2014-02/uow...

Researchers have discovered the presence of a novel subtype of innate lymphoid cells in human spleen essential for the production of antibodies. This discovery, published in the prestigious journal Nature Immunology, clears the path to the identification of novel strategies to develop more...

The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers from the Niels Bohr Institute, among others, have detected a stream of stars in one of the Andromeda Galaxy's outer satellite galaxies, a dwarf galaxy called Andromeda II. The movement of the stars tells us that...

Researchers have determined that a small region of the hippocampus known as CA2 is essential for social memory, the ability of an animal to recognize another of the same species. A better grasp of the function of CA2 could prove useful in understanding and treating disorders characterized by...

Researchers at the University of Illinois at Chicago have developed a system for precisely delivering anti-inflammatory drugs to immune cells gone out of control, while sparing their well-behaved counterparts. Their findings were published online Feb. 23 in Nature Nanotechnology. Fuente :...

New research published today (Sunday, Feb. 23) has found that climate change is unlikely to reduce the United Kingdom's excess winter death rate as previously thought. The study is published in the journal Nature Climate Change and debunks the widely held view that warmer winters will cut the...

An international team of researchers have discovered a 'microbial Pompeii' preserved on the teeth of skeletons around 1,000 years old. The key to the discovery is the dental calculus (plaque) which preserves bacteria and microscopic particles of food on the surfaces of teeth, effectively creating a...

New Rochelle, NY, February 21, 2014-Even small increases in blood sugar caused by a diet high in carbohydrates can be detrimental to brain health. Recent reports in medical literature link carbohydrate calorie-rich diets to a greater risk for brain shrinkage, dementia and Alzheimer's disease,...

The Urban Design Group’s National Urban Design Awards 2014 were presented on February 12th and the evening showcased some great examples of urban design work produced throughout the UK over the past twelve months. Lucy Bullivant’s title "Masterplanning Futures" was awarded the 2014 Book of the Year...

Las pesquerías que dependen de especies de corta vida, como la sardina o el camarón, han sido las más susceptibles a resentir los efectos del cambio climático, ya que este fenómeno afecta la producción de clorofila, que es la base para la producción de fitoplancton, alimento de ambas especies....

A lung-damaging molecule has been discovered in higher concentrations in cystic fibrosis patients during symptom flare-ups. This molecule, which has a buttery flavor and is the main ingredient in microwave popcorn flavoring, is toxic and has been implicated in damaging the lungs of popcorn factory...

A new naming structure proposed by an American researcher moves beyond the Linnaeus system to one based on the genetic sequence of each individual organism. This creates a more robust, precise, and informative name for any organism, be it a bacterium, fungus, plant, or animal. Coded names could be...

Placing seedpods in a pearl net, tethered by a rope but allowed to sway with the tides, may be an especially effective way of restoring eelgrass meadows. The resulting crop of eelgrass grown for this study was as genetically diverse as the beds from which the seeds were harvested, which researchers...

Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains. Scientists have now combined cheap, oxide-based materials to split water into...

Although levels of furan—a carcinogen resulting from heat treatment techniques, such as canning and jarring—are far below of what would cause harmful effect as determined by the Federal Drug Administration (FDA), a team of food scientists found that treatment of baby food puree with high pressure thermal sterilization (HPTS)...

Recent developments across the globe have put an increasing focus on the traceability of foods. Complicated supply chains of hundreds of ingredients that are used to make a food product make food product tracing a daunting task. In an effort to better protect public health from foodborne illness...

High-dose supplementation with both the trace element selenium and vitamin E increase the risk of high-grade prostate cancer. But importantly, this risk depends upon a man’s selenium status before taking the supplements. "Men using these supplements should stop, period. Neither selenium nor vitamin...

An antibody found in the blood of people with multiple sclerosis may be present long before the onset of the disease and its symptoms, according to a study.
