Caribbean's native predators unable to stop aggressive lionfish population growth Posted: 11 Jul 2013 02:25 PM PDT "Ocean predator" conjures up images of sharks and barracudas, but the voracious red lionfish is out-eating them all in the Caribbean -- and Mother Nature appears unable to control its impact on local reef fish. That leaves human intervention as the most promising solution to the problem of this highly invasive species, said researchers.

Lionfish expedition: Down deep is where the big, scary ones live Posted: 11 Jul 2013 02:25 PM PDT The first expedition to use a deep-diving submersible to study the Atlantic Ocean lionfish invasion found something very disturbing -- at 300 feet deep, there were still significant populations of these predatory fish, and they were big. Big fish can reproduce much more efficiently than their younger, smaller counterparts, and lionfish can travel. This raises significant new concerns in the effort to control this invasive species that is devastating native fish populations on the Atlantic Coast and in the Caribbean Sea.

'Taste sensor' genes in female butterflies vital to species' survival Posted: 11 Jul 2013 02:25 PM PDT Giving the phrase "Mother knows best" a whole new meaning, researchers have identified unique genes in female butterflies that enable them to select the best host plant for their larvae -- and avoid deadly ones.

Scientists cast doubt on theory of what triggered Antarctic glaciation Posted: 11 Jul 2013 11:24 AM PDT Scientists have found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica's ice sheet began forming. They report finding an ancient volcanic arc in the Scotia Sea that might have prevented the Antarctic Circumpolar Current from forming until millions of years after Antarctic glaciation began.

Gene therapy using lentivirus to treat Wiskott-Aldrich Syndrome promising Posted: 11 Jul 2013 11:24 AM PDT Researchers have developed a new gene therapy approach to treatment of Wiskott-Aldrich Syndrome, a fatal inherited form of immunodeficiency.

Distant earthquakes trigger tremors at U.S. waste-injection sites, says study Posted: 11 Jul 2013 11:24 AM PDT Large earthquakes from distant parts of the globe are setting off tremors around waste-fluid injection wells in the central United States, says a new study. Furthermore, such triggering of minor quakes by distant events could be precursors to larger events at sites where pressure from waste injection has pushed faults close to failure, say researchers. Among the sites covered are central Oklahoma, western Texas and southern Colorado.

Nerves play key role in triggering prostate cancer and influencing its spread Posted: 11 Jul 2013 11:23 AM PDT Researchers have found that nerves play a critical role in both the development and spread of prostate tumors. Their findings, using both a mouse model and human prostate tissue, may lead to new ways to predict the aggressiveness of prostate cancer and to novel therapies for preventing and treating the disease.

Geothermal power facility induces earthquakes, study finds Posted: 11 Jul 2013 11:23 AM PDT An analysis of earthquakes in the area around the Salton Sea Geothermal Field in southern California has found a strong correlation between seismic activity and operations for production of geothermal power, which involve pumping water into and out of an underground reservoir.

The brain processes complex stimuli more cumulatively than we thought Posted: 11 Jul 2013 11:23 AM PDT A new study reveals that the representation of complex features in the brain may begin in a hierarchically lower brain region than previously thought.

Buying behavior can be swayed by cultural mindset Posted: 11 Jul 2013 10:57 AM PDT People with collectivist mindsets tend to value the relationships between items more than the particular items themselves. Those with individualistic mindsets seem to do just the opposite.

Cry analyzer seeks clues to babies' health Posted: 11 Jul 2013 10:56 AM PDT Researchers have developed a new tool that analyzes the cries of babies, searching for clues to potential health or developmental problems. Slight variations in cries, mostly imperceptible to the human ear, can be a "window into the brain" that could allow for early intervention.

Writing computer programs using ordinary language: Systems convert ordinary language to code Posted: 11 Jul 2013 10:56 AM PDT Researchers have demonstrated that, for a few specific tasks, it's possible to write computer programs using ordinary language rather than special-purpose programming languages. The work may be of some help to programmers, and it could let nonprogrammers manipulate common types of files -- like word-processing documents and spreadsheets -- in ways that previously required familiarity with programming languages.

Snakes devour more mosquito-eating birds as climate change heats forests Posted: 11 Jul 2013 10:55 AM PDT Rising temperatures threaten wild birds, including the Missouri-native Acadian flycatcher, by making snakes more active, according to biologists. They noted that farmers, public health officials and wildlife managers should be aware of complex indirect effects of climate change in addition to the more obvious influences of higher temperatures and irregular weather patterns.

Why do we enjoy listening to sad music? Posted: 11 Jul 2013 10:54 AM PDT Sad music might actually evoke positive emotions, reveals a new study by Japanese researchers.

Ground-breaking new method of 'starving' cancer cells Posted: 11 Jul 2013 10:54 AM PDT Researchers have discovered a novel way of killing cancer cells.

Obese dads pass on predisposition to obesity and metabolic disorders to their kids Posted: 11 Jul 2013 10:54 AM PDT If you are obese and hope to be a father, here's another reason to lose weight: your children and grandchildren may inherit your waistline or metabolic disorders. Scientists have discovered in mice that obese fathers, even those with no symptoms of diabetes, passed this negative trait on most frequently to their daughters. Sons don't dodge this genetic bullet either -- both sons and daughters of obese fathers have increased risks of developing metabolic diseases.

Whole chickens from farmers markets may have more pathogenic bacteria Posted: 11 Jul 2013 10:54 AM PDT Raw, whole chickens purchased from farmers markets throughout Pennsylvania contained significantly higher levels of bacteria that can cause foodborne illness compared to those purchased from grocery stores in the region, according to a small-scale study.

In fact, the evidence is so strong that the researchers believe it's time to revise the killer whale stocks in the region.

Hippo pathway to better cancer treatment? Unusual key to regulating cell growth Posted: 11 Jul 2013 10:53 AM PDT Researchers have discovered a potential new pathway to treat cancer by asking some odd questions about the size of animals.

As ice cover disappears, life in frigid Antarctic moves fast Posted: 11 Jul 2013 10:53 AM PDT It might be cold in the Antarctic, but that doesn't mean that life there necessarily moves slowly. A new article reveals the discovery of a surprisingly fast-growing community of glass sponges in an area formerly covered by permanent ice. With the ice at the surface disappearing, those little-known sponges are launching a seafloor takeover.

Critical pathway in cell cycle may lead to cancer development Posted: 11 Jul 2013 10:52 AM PDT Researchers' findings on chromosome shortening suggest a potential target to arrest cancer cell growth.

Researchers regenerate retina in mice using neuronal reprogramming Posted: 11 Jul 2013 10:47 AM PDT Researchers in Spain have managed to regenerate the retina in mice using neuronal reprogramming. There are currently several lines of research that explore the possibility of tissue regeneration through cell reprogramming. One of the mechanisms being studied is reprogramming through cell fusion.

Discovery of a strange new snow scorpionfly species in Alaska helped by Facebook Posted: 11 Jul 2013 08:34 AM PDT Researchers have discovered a strange new insect on Prince of Wales Island, Alaska.

Stellar monsters do not collide: No hope for a spectacular catastrophe Posted: 11 Jul 2013 07:31 AM PDT One might expect that collisions between the remains of monstrous stars, with masses reaching 200-300 times that of our Sun, would be among the most spectacular phenomena in the Universe. Perhaps they are, but we will unfortunately probably never have the chance to find out. Astrophysicists have discovered that the first such collisions will not occur until billions of years from now.

New insight into the human genome through the lens of evolution Posted: 11 Jul 2013 07:31 AM PDT By comparing the human genome to the genomes of 34 other mammals, Australian scientists have described an unexpectedly high proportion of functional elements conserved through evolution. While other studies have shown that around 5-8 percent of the genome is conserved at the level of DNA sequence, indicating that it is functional, the new study shows that in addition much more, possibly up to 30 percent, is also conserved at the level of RNA structure.

Acceptance of what cannot be changed predicts satisfaction in later life Posted: 11 Jul 2013 07:30 AM PDT Accepting what cannot be changed is key to happiness in old age after loss of independence. When older adults lose control as they move into residential care, they adapt and accept what cannot be changed in order to stay happy. According to a new study, when it comes to satisfaction in later life the ability to accept what cannot be changed is as important as the feeling of being able to exert control.

Trapping T-rays for better security scanners Posted: 11 Jul 2013 07:29 AM PDT Medical diagnostic and security scanners with higher sensitivity could result from new research into detecting T-rays (terahertz waves).

If seen directly the planet, known as HD 189733b, would look like a "deep blue dot," reminiscent of Earth's color as seen from space.

Size matters for creatures of cold polar waters Posted: 11 Jul 2013 05:49 AM PDT Scientists have challenged the view that giant animals are found in polar seas because of a superabundance of oxygen in cold water.

Later cord clamping after birth increases iron levels in babies Posted: 11 Jul 2013 05:49 AM PDT Delaying clamping of the umbilical cord after birth benefits newborn babies, according to a systematic review. The authors found babies' blood and iron levels were healthier when the cord was clamped later.

Race for new temperature definition: Most accurate measurement yet of Boltzmann constant Posted: 11 Jul 2013 05:48 AM PDT Scientists have performed the most accurate measurement yet of the Boltzmann constant. While the impact of such an achievement is not immediately obvious, the measurement could revolutionize the way we define temperature, replacing the standard method that has been used for over 50 years.

Bioenergy with carbon capture: Scientists set out path for global warming reversal Posted: 11 Jul 2013 05:48 AM PDT Bioenergy with carbon capture and storage can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially overshoot this target.

Do antibiotics in animal feed pose a serious risk to human health? Posted: 11 Jul 2013 05:48 AM PDT As fears rise over antibiotic resistance, two experts debate whether adding antibiotics to animal feed poses a serious risk to human health.

Combination of smoking and heavy drinking 'speeds up cognitive decline' Posted: 11 Jul 2013 05:47 AM PDT The combination of smoking and heavy drinking speeds up cognitive decline, according to new research.

Bioluminescence reveals deep-water motion in the Mediterranean Posted: 11 Jul 2013 05:45 AM PDT In 2009 and 2010, the underwater neutrino telescope ANTARES detected an unusual phenomenon: the bioluminescence of deep-sea organisms suddenly increased, revealing an unexpected connection between biological activity -- bioluminescence -- and the motion of water masses in the deep ocean. Convective motion in the Gulf of Lion provides deep waters with oxygen and nutrients that boost biological activity.

Parental divorce in childhood is linked to raised inflammation in adulthood Posted: 11 Jul 2013 05:45 AM PDT People who experience parental divorce during childhood have higher levels of an inflammatory marker in the blood which is known to predict future health, according to new research from the United Kingdom.

Cells make costume changes for cardiac regeneration Posted: 11 Jul 2013 05:45 AM PDT If the heart following a heart attack is not sufficiently supplied with blood, heart tissue dies. In adult humans, the ability to heal itself is hardly developed. Scientists have now observed in the embryo of the zebrafish that muscle cells migrate from the undamaged atrium into the ventricle and thus significantly contribute to regeneration. This could serve as the basis for novel therapeutic approaches.

Surprising detail about skin cancer uncovered Posted: 11 Jul 2013 05:41 AM PDT An international team of melanoma researchers confirmed that the chances of dying from skin cancer depend strongly upon how thick the primary tumor is. But -- unexpectedly -- the team also found that those having more than one primary tumor have better survival odds.
