Preventing cancer development inside the cell cycle Posted: 21 Oct 2011 04:55 PM PDT Researchers have identified a cell cycle-regulated mechanism behind the transformation of normal cells into cancerous cells. The study results suggest that inhibition of the CK1 enzyme may be a new therapeutic target for the treatment of cancer cells formed as a result of a malfunction in the cell's mTOR signaling pathway.

Cooling the warming debate: Major new analysis confirms that global warming is real Posted: 21 Oct 2011 11:47 AM PDT Global warming is real, according to a major new study. Despite issues raised by climate change skeptics, the Berkeley Earth Surface Temperature study finds reliable evidence of a rise in the average world land temperature of approximately 1 degree Celsius since the mid-1950s.

US residents say Hawaii's coral reef ecosystems worth $33.57 billion per year Posted: 21 Oct 2011 10:50 AM PDT The American people assign an estimated total economic value of $33.57 billion for the coral reefs of the main Hawaiian Islands. The findings came from survey of 3,100 households -- from all US residents, not just Hawaii or coastal residents. Survey allowed the public to express its preferences and values for protection and restoration of the coral reef ecosystems around the main Hawaiian Islands.

'Trading places' most common pattern for couples dealing with male depression Posted: 21 Oct 2011 09:58 AM PDT Researchers have identified three major patterns that emerge among couples dealing with male depression. These can be described as "trading places," "business as usual" and "edgy tensions."

Plants feel the force: How plants sense touch, gravity and other physical forces Posted: 21 Oct 2011 09:57 AM PDT At the bottom of plants' ability to sense touch, gravity or a nearby trellis are mechanosensitive channels, pores through the cells' plasma membrane that are opened and closed by the deformation of the membrane. Biologists are studying the roles these channels play in Arabdopsis plants by growing mutant plants that lack one or more of the 10 possible channel proteins in this species.

Blood-pressure-lowering drug after stroke aids recovery, study suggests Posted: 21 Oct 2011 09:57 AM PDT A commonly prescribed blood pressure-lowering medication appears to kick start recovery in the unaffected brain hemisphere after a stroke by boosting blood vessel growth, a new study has found.

Decision-making: What you want vs. how you get it Posted: 21 Oct 2011 09:57 AM PDT New research reveals how we make decisions. Birds choosing between berry bushes and investors trading stocks are faced with the same fundamental challenge -- making optimal choices in an environment featuring varying costs and benefits.

Fluoride shuttle increases storage capacity: Researchers develop new concept for rechargeable batteries Posted: 21 Oct 2011 09:55 AM PDT Researchers have developed a new concept for rechargeable batteries. Based on a fluoride shuttle -- the transfer of fluoride anions between the electrodes -- it promises to enhance the storage capacity reached by lithium-ion batteries by several factors. Operational safety is also increased, as it can be done without lithium.

Biomarker detects graft-versus-host-disease in cancer patients after bone marrow transplant Posted: 21 Oct 2011 09:55 AM PDT A team of researchers has found a biomarker they believe can help rapidly identify one of the most serious complications in cancer patients after a bone marrow transplant.

Plate tectonics may control reversals in Earth's magnetic field Posted: 21 Oct 2011 05:45 AM PDT Earth's magnetic field has reversed many times at an irregular rate throughout its history. Long periods without reversal have been interspersed with eras of frequent reversals. What is the reason for these reversals and their irregularity? Researchers have shed new light on the issue by demonstrating that, over the last 300 million years, reversal frequency has depended on the distribution of tectonic plates on the surface of the globe. This result does not imply that terrestrial plates themselves trigger the switch over of the magnetic field. Instead, it establishes that although the reversal phenomenon takes place, in fine, within Earth's liquid core, it is nevertheless sensitive to what happens outside the core and more specifically in Earth's mantle.

Florida Keys ecosystem threatened by multiple stressors Posted: 21 Oct 2011 04:47 AM PDT Scientists have found that pressure from increasing coastal populations, ship and boat groundings, marine debris, poaching, and climate change are critically threatening the health of the Florida Keys ecosystem.

Elaborate bird plumage due to testosterone? Posted: 21 Oct 2011 04:47 AM PDT In many bird species males have a more elaborate plumage than females. This elaborate plumage is often used to signal body condition, to intimidate rivals or to attract potential mates. In many cases plumage colouration also depends on the hormone testosterone. Researchers have now investigated whether this also holds true for sex role-reversed bird species.

Simple lifestyle changes can add a decade or more healthy years to the average lifespan, Canadian study shows Posted: 21 Oct 2011 04:47 AM PDT Health prevention strategies to help people achieve their optimal health potential could add a decade or more of healthy years to the average lifespan and save the economy billions of dollars as a result of reduced cardiovascular disease.

Issues faced by friends and family of the suicidal Posted: 21 Oct 2011 04:47 AM PDT A study focusing on the family and friends of people who were suicidal has highlighted the main challenges they face when trying to judge whether a person is in danger and decide what they should do about it.

Poor cerebral cortex functions leads to more impulsive behavior Posted: 21 Oct 2011 04:46 AM PDT If the front part of the cerebral cortex is less active then people have less control over their social behavior and automatically follow their inclinations more. The research was the first to make use of magnetic stimulation (TMS) to suppress this part at the front of the prefrontal cortex. During TMS a changing magnetic field on the head temporarily influences the activity of the underlying part of the brain.

New study shows no simultaneous warming of northern and southern hemispheres as a result of climate change for 20,000 years Posted: 21 Oct 2011 04:45 AM PDT A common argument against global warming is that the climate has always varied. Temperatures rise sometimes and this is perfectly natural is the usual line. However, a climate researcher has now shown that global warming, i.e. simultaneous warming events in the northern and southern hemispheres, have not occurred in the past 20 000 years, which is as far back as it is possible to analyze with sufficient precision to compare with modern developments.

First Ebola-like virus native to Europe discovered Posted: 20 Oct 2011 04:18 PM PDT Researchers have discovered a new Ebola-like virus -- Lloviu virus -- in bats from northern Spain. Lloviu virus is the first known filovirus native to Europe. Filoviruses, which include well-known viruses like Ebola and Marburg, are among the deadliest pathogens in humans and non-human primates, and are generally found in East Africa and the Philippines. The findings thus expand the natural geographical distribution of filoviruses.

Giant flakes make graphene oxide gel: Discovery could boost metamaterials, high-strength fibers Posted: 20 Oct 2011 02:14 PM PDT Slices of graphene oxide in a solution arrange themselves into a nematic liquid crystal. At a sufficient concentration, giant flakes will form a gel, a precursor to manufacturing metamaterals and fibers.

A passing mood can profoundly alter 'rational decisions' Posted: 20 Oct 2011 07:59 AM PDT Could a passing mood influence your financial portfolio for decades to come? Can impulses you inherited from your cave-man ancestors influence your financial decisions in the modern world in ways that may have lifelong consequences? In a word, yes. Researchers report new evidence that passing mood and deeply embedded human impulses can and do influence us as we make important financial decisions.

Ancient depiction of childbirth discovered at Etruscan site in Tuscany Posted: 19 Oct 2011 11:57 PM PDT An archaeological excavation at Poggio Colla, the site of a 2,700-year-old Etruscan settlement in Italy's Mugello Valley, has turned up a surprising and unique find: two images of a woman giving birth to a child. Researchers who oversee the Poggio Colla excavation site some 20 miles northeast of Florence, discovered the images on a small fragment from a ceramic vessel that is more than 2,600 years old.
