Baby wash does not damage baby's skin barrier function, study finds Posted: 18 Feb 2013 05:15 PM PST New research has found washing newborn babies in a specific baby wash is just as safe as using water alone in terms of maintaining healthy skin.

Caffeine linked to low birth weight babies Posted: 18 Feb 2013 05:15 PM PST Maternal nutrition is important to a developing embryo and to the health of the child later in life. Supplementing the diet with specific vitamins is known to increase health of the fetus for example folic acid (vitamin B9) reduces the risk of spina bifida. However not everything an adult might consume is beneficial to a developing baby. New research shows that caffeine is linked to low birth weight babies and that caffeine from coffee in linked to increasing length of pregnancy.

A solution to sinusitis from the sea Posted: 18 Feb 2013 02:33 PM PST Scientists and surgeons are developing a new nasal spray from a marine microbe originally being investigated to clear the hulls of ships in order to help clear chronic sinusitis.

Meerkats use subordinate animals as guinea pigs when approaching novel threats Posted: 18 Feb 2013 02:32 PM PST In their environment, wild animals are exposed to countless threats, be they predators, diseases or natural obstacles to get over, such as gorges or rivers. In recent times, numerous human-made threats have been added to the naturally-existing ones, such as dangerous roads to cross. Scientists have worked to understand how animals cope with novel human-made threats by studying groups of wild meerkats, a species of socially-living mongooses.

Could a computer on the police beat prevent violence? Posted: 18 Feb 2013 01:41 PM PST As cities work to reduce violence in tight budget times, new research shows how they might be able to target their efforts and police attention on areas prone to violence – with the help of high-powered computers and loads of data on crime, alcohol availability and drug markets.

Ancient fossilized sea creatures yield oldest biomolecules isolated directly from a fossil Posted: 18 Feb 2013 01:41 PM PST Though scientists have long believed that complex organic molecules couldn't survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption.

Molecules generated that can halt metastasis of colon cancer Posted: 18 Feb 2013 06:25 AM PST Medical researchers have managed to halt the progress of colon cancer and its metastasis in the liver in an experimental model with mice. This advance, that may open a new path for the future treatment of such pathologies, has been achieved by creating molecules which interfere with the adhesion of tumor cells to other cells of the organism. In this way, the molecules halt both the growth of the tumor and the dissemination of the tumor to and its proliferation in other organs.

Blood is thicker than water – and blood plasma is, too Posted: 18 Feb 2013 06:25 AM PST Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically. The similarity between blood and ketchup is something not only filmmakers are aware of. Experts refer to these materials as "non-Newtonian fluids," of which ketchup and blood are prime examples. These fluids have flow properties that change depending on conditions, with some becoming more viscous, while others become less viscous.

Living organisms need antifreeze to survive in the cold Posted: 18 Feb 2013 06:25 AM PST If you thought antifreeze was only something that was necessary to keep your car from freezing up in the winter, think again.  Plants and animals living in cold climates have natural antifreeze proteins (AFPs) which prevent ice growth and crystallization of organic fluid matter. Without such antifreeze, living matter would suffer from frost damage and even death.

The findings could potentially point to new ways to design superconductors with improved properties.

Forging a new periodic table using nanostructures: Artificial atoms and bonds provide a new set of building blocks for future materials Posted: 17 Feb 2013 10:42 AM PST Scientists have developed a new set of building blocks based on nanoparticles and DNA. Using these tools, scientists will be able to build -- from the bottom up, just as nature does -- new and useful structures. The research team has already built more than 200 different crystal structures with 17 different particle arrangements. Some of the lattice types can be found in nature, but many are new structures that have no naturally occurring mineral counterpart.

A reoccurring problem in this technology is to establish good electrical contact between the active organic layer and metal electrodes. Organic molecules are frequently used also for this purpose.

'Activating' RNA takes DNA on a loop through time and space Posted: 17 Feb 2013 10:42 AM PST Long segments of RNA -- encoded in our DNA but not translated into protein -- are key to physically manipulating DNA in order to activate certain genes, say researchers. These non-coding RNA-activator molecules help create a loop of DNA to open up genes for transcription. They have a crucial role in turning genes on and off during early embryonic development, and have also been connected with genetic diseases, such as FG syndrome, and cancer.

Genetically modified crops are overregulated, food science expert says Posted: 17 Feb 2013 10:42 AM PST Scientists argue that genetically modified foods are safe for consumption and overregulated.

These results may shed light on the neuropathology of AD and open up new avenues of treatment.

Possible link between diabetes and increased risk of heart attack death Posted: 17 Feb 2013 05:52 AM PST Having diabetes doubles a person's risk of dying after a heart attack, but the reason for the increased risk is not clear. A new study suggests the link may lie in the over-activation of an important heart enzyme, which leads to death of pacemaker cells, abnormal heart rhythm, and increased risk of sudden death in diabetic mice following a heart attack.

New enzyme that acts as innate immunity sensor discovered Posted: 17 Feb 2013 05:50 AM PST Two studies could lead to new treatments for lupus and other autoimmune diseases and strengthen current therapies for viral, bacterial, and parasitic infections.

Neuronal activity induces tau release from healthy neurons Posted: 17 Feb 2013 05:50 AM PST Researchers have discovered that neuronal activity can stimulate tau release from healthy neurons in the absence of cell death. The results show that treatment of neurons with known biological signaling molecules increases the release of tau into the culture medium. The release of tau from cortical neurons is therefore a physiological process that can be regulated by neuronal activity.
