E-cigarettes supply nicotine through inhaled water vapor. While the addictiveness and long-term effects of using e-cigarettes as a nicotine delivery system are unknown, many people anecdotally believe that they are safer than traditional tobacco products. According to a new study published in the...

We ring in the new year with hopes of being healthy, wealthy, and wise. A new study led by SDSU professor John Ayers suggests that from a public health standpoint, health and wealth may be connected.Ayers and his team examined Google search patterns during the recent recession and discovered that...

A special issue on sepsis has been released by the publisher Landes Bioscience. The articles contained in this special issue of the journal Virulence have been authored by world-class investigators and provide new insights into both the pathogen-related factors and the host defense mechanisms that...

The development of new, more effective vasodilators to treat pulmonary arterial hypertension has been hampered because of their systemic toxicity and adverse side effects. An international team of investigators seeking to surmount these problems and increase drug efficacy have determined that a vascular homing peptide can...

A Yale study estimates that 8 million lives have been saved in the United States as a result of anti-smoking measures that began 50 years ago this month with the groundbreaking report from the Surgeon General outlining the deadly consequences of tobacco use. The Yale School of Public Health-led analysis is published in the...

The sun emitted a significant solar flare peaking at 1:32 p.m. EST on Jan. 7, 2014. This is the first significant flare of 2014, and follows on the heels of mid-level flare earlier in the day. Each flare was centered over a different area of a large sunspot group currently situated at the center of the sun, about half way...

An enormous sunspot, labeled AR1944, slipped into view over the sun's left horizon late on Jan. 1, 2014. The sunspot steadily moved toward the right, along with the rotation of the sun, and now sits almost dead center, as seen in the image above from NASA's Solar Dynamics Observatory. Fuente :...

NASA's Hubble Space Telescope is providing a new perspective on the remote universe, including new views of young and distant galaxies bursting with stars.

A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new study indicates that the brain regions involved in sensory perception also develop differently in these castes, according to...

A new study discusses the origins of cats and dogs, as well as other carnivorous mammals like bears, seals, and weasels (taxonomically called "carnivoraformes"), and describes new specimens of one of the earliest of these primitive taxa.

An international team of astronomers has discovered the first Earth-mass planet that transits, or crosses in front of, its host star. KOI-314c is the lightest planet to have both its mass and physical size measured. Surprisingly, although the planet weighs the same as Earth, it is 60 percent larger...

One of the most hotly debated issues in current human origins research focuses on how the 4.4 million-year-old African species Ardipithecus ramidus is related to the human lineage. New research confirms "Ardi's" close evolutionary relationship to humans. Researchers turned to the base of a...

Researchers have pioneered a tabletop magnetic pulse generator that allows researchers to collect real-time, high-resolution data in a system that couples high magnetic fields and low temperature with direct optical access to the magnet's core. Fuente :...

Gifted children are likely to be the next generation's innovators and leaders—and yet, the exceptionally smart are often invisible in the classroom, lacking the curricula, teacher input and external motivation to reach full potential. This conclusion comes as the result of the largest scientific...

Researchers have discovered that bacteria prevent layabouts from enjoying the fruit of others' hard work by keeping food generated by the community's productive members away from those microbes that attempt to live on others' leftovers. The process could have uses in agriculture, energy and...

Although complications from surgical care for cancer patients may seem infrequent, the costs associated with such outcomes are extremely high, according to researchers. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/w...

Researchers have discovered novel compounds produced by certain types of chemical reactions -- such as those found in vehicle exhaust or grilling meat -- that are hundreds of times more mutagenic than their parent compounds which are known carcinogens. These compounds were not previously known to...

A new idea to cut back on air pollution: spray water into the atmosphere from sprinklers atop tall buildings and towers, similar to watering a garden. In an article published, a researcher suggests this course of action as a novel approach to help curb the severe air pollution and heavy haze....
