Genomic differences found in types of cervical cancer Posted: 23 Aug 2013 01:38 PM PDT A new study has revealed marked differences in the genomic terrain of the two most common types of cervical cancer, suggesting that patients might benefit from therapies geared to each type's molecular idiosyncrasies.

Refrigerated trucks to keep their cool thanks to fuel cell technology Posted: 23 Aug 2013 01:38 PM PDT Grocery merchants in Texas, California and New York will soon have ice cream, frozen foods and fresh produce delivered by tractor trailers whose refrigeration units are powered by fuel cells, which will do the work normally done by a small diesel engine to keep the cargo at the proper temperature while the trucks are making deliveries.

Unprecedented control of genome editing in flies promises insight into human development, disease Posted: 23 Aug 2013 01:38 PM PDT In an era of widespread genetic sequencing, the ability to edit and alter an organism's DNA is a powerful way to explore the information within and how it guides biological function.

Out of Africa? New bamboo genera, mountain gorillas, and the origins of China's bamboos Posted: 23 Aug 2013 07:23 AM PDT African mountain bamboos look like Asian bamboos, with Mountain Gorillas instead of Giant Pandas, but research has shown that they are as different to Asian bamboos as the Gorilla is to the Panda, and they represent two completely new genera. Bamboos evolved in Gondwanaland, and how they reached China is unknown. Like modern humans they could have came 'Out of Africa', but it now seems more likely they were a gift to China from India.

Omega-3 reduces ADHD symptoms in rats Posted: 23 Aug 2013 06:43 AM PDT A new multidisciplinary study shows a clear connection between the intake of omega-3 fatty acids and a decline in ADHD symptoms in rats.

Underwater intelligence: How do you track a fish underwater? Posted: 23 Aug 2013 06:43 AM PDT How do you track a fish underwater? Rethinking the traditional, ad hoc approach to acoustic telemetry, scientists have proposed a new state-space model for analyzing fish movement data collected by marine observation networks. Its goal is to quantify the uncertainty associated with this imperfect locating system, and to improve its accuracy.

Sea ice decline spurs the greening of the Arctic Posted: 23 Aug 2013 06:43 AM PDT Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to scientists.

Higher intake of fruits and vegetables may reduce the risk of bladder cancer in women Posted: 23 Aug 2013 06:43 AM PDT Scientists recently discovered that a greater consumption of fruits and vegetables may lower the risk of invasive bladder cancer in women.

New technique to help brain cancer patients Posted: 23 Aug 2013 06:43 AM PDT A new scanning technique reveals how susceptible patients with aggressive brain cancer are to the drugs they receive.

Gut taste mechanisms are abnormal in diabetes sufferers Posted: 23 Aug 2013 06:42 AM PDT Researchers have discovered that the way the gut "tastes" sweet food may be defective in sufferers of type 2 diabetes, leading to problems with glucose uptake.

Favorite music makes teens drive badly: Teen driver music preferences increase errors and distractibility Posted: 23 Aug 2013 06:13 AM PDT When the teen drivers listened to their preferred music, virtually all (98 percent) demonstrated an average of three deficient driving behaviors in at least one of the trips. Nearly a third of those (32 percent) required a a sudden verbal warning or command for action, and 20 percent needed an assisted steering or braking maneuver to prevent an imminent accident. These errors included speeding, tailgating, careless lane switching, passing vehicles and one-handed driving.

Architecture of chromosomes: A key for success or failure Posted: 23 Aug 2013 06:13 AM PDT Scientists have shown for the first time that chromosomes rearrangements (such as inversions or translocations) can provide advantages to the cells that harbor them depending on the environment to which they are exposed.

Richard III’s skeleton came within inches of destruction Posted: 23 Aug 2013 06:11 AM PDT Archaeologists have revealed the bones of Richard III came within inches of destruction.

One mummy, many coffins: Egyptians intended to transform deceased from human to deity Posted: 23 Aug 2013 06:11 AM PDT The Egyptian elite was buried in a coffin placed inside another coffin -- in ensembles of up to eight coffins. This was intended to ensure the transformation of the deceased from human to deity, according to an Egyptologist.

Two become one with the 3-D NanoChemiscope: Unique surface analysis instrument Posted: 23 Aug 2013 06:11 AM PDT The 3D NanoChemiscope is a miracle of state-of-the-art analysis technology. As a further development of well-known microscopic and mass spectroscopic methods, it maps the physical and chemical surfaces of materials down to the atomic level. This instrument, which is unique in the world, not only delivers high-definition images; it also knows what it is "seeing".

A fluffy disk around a baby star Posted: 23 Aug 2013 06:11 AM PDT Astronomers have observed a disk around the young star RY Tau (Tauri). The team's analysis of the disk shows that a "fluffy" layer above it is responsible for the scattered light observed in the infrared image. Detailed comparisons with computer simulations of scattered light from the disk reveal that this layer appears to be a remnant of material from an earlier phase of stellar and disk development, when dust and gas were falling onto the disk.

Receptor may aid spread of Alzheimer's and Parkinson's in brain Posted: 23 Aug 2013 06:09 AM PDT Scientists have found a way that corrupted, disease-causing proteins spread in the brain, potentially contributing to Alzheimer's disease, Parkinson's disease and other brain-damaging disorders.

Arctic sea ice update: Unlikely to break records, but continuing downward trend Posted: 23 Aug 2013 06:08 AM PDT The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year. While the ice will continue to shrink until around mid-September, it is unlikely that this year's summer low will break a new record. Still, this year's melt rates are in line with the sustained decline of the Arctic ice cover observed by NASA and other satellites over the last several decades.

Drug used for blood cancers may stop spread of breast cancer cells Posted: 22 Aug 2013 12:21 PM PDT A drug used to treat blood cancers may also stop the spread of invasive breast cancer, researchers have discovered. Their study found that in the lab and in animals, the drug decitabine turns on a gene coding for protein kinase D1 (PRKD1) that halts the ability of cancer cells to separate from a tumor and spread to distant organs.
