Unwrapping DNA delivers cell insights
University scientists have shed light on how DNA is compacted as cells divide, helping explain how cell renewal can fail. Thousands of proteins have been discovered which are crucial for the compaction of DNA up to 10,000 times its usual size, which occurs when cells split in two. This research could shed light on what happens when this packaging process fails and cells divide abnormally, which can cause cancer and embryo miscarriage.

Scientists Create New Process to "Program" Cancer Cell Death
PASADENA, Calif.—Researchers at the California Institute of Technology (Caltech) have engineered a fundamentally new approach to killing cancer cells. The process—developed by Niles Pierce, associate professor of applied and computational mathematics and bioengineering at Caltech, and his colleagues—uses small RNA molecules that can be programmed to attack only specific cancer cells; then, by changing shape, those molecules cause the cancer cells to self-destruct.

Cockroach brains could be rich stores of new antibiotics
PA230/10 Cockroaches could be more of a health benefit than a health hazard according to scientists from The University of Nottingham. Experts from the School of Veterinary Medicine and Science have discovered powerful antibiotic properties in the brains of cockroaches and locusts which could lead to novel treatments for multi-drug resistant bacterial infections.

Caltech Chemists Develop Simple Technique to Visualize Atomic-Scale Structures
PASADENA, Calif.—Researchers at the California Institute of Technology (Caltech) have devised a new technique—using a sheet of carbon just one atom thick—to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules.

Research demonstrates benefits of medical cannabis as a treatment for chronic pain
The medicinal use of cannabis has been debated by clinicians, researchers, legislators and the public at large for many years as an alternative to standard pharmaceutical treatments for pain, which may not always be effective and may have unwanted side effects. A new study by McGill University Health Centre (MUHC) and McGill University researchers provides evidence that cannabis may offer relief to patients suffering from chronic neuropathic pain.

Bacteria make thrift a habit, U-M researchers find
ANN ARBOR, Mich.—In these lean times, smart consumers refuse to pay a lot for throwaway items, but will shell out a little more for products that can be used again and again. The same is true of bacteria and other microbes, researchers at the University of Michigan have learned. Some proteins cost more (in terms of energy) for cells to produce than others.

Faithful females key to evolution of bird societies
Science 19 Aug 10 Females with fewer sexual partners can explain where bird species have evolved to cooperate in the rearing of their young, according to Oxford University research. In a study of 267 bird species, the researchers found that promiscuity rates overall were three times higher among species that show no social cooperation than in species where adult birds other than the parents help in raising chicks, for example by assisting in providing food, incubation or defence.

Measuring the speed of thought
If the eyes are the window to the soul, psychologists hoping to solve the mystery of why our neural impulses do not always trigger an immediate response could find the answer in the flick of the eye. The reasons why the speed of human responses to a given event can be so variable - even in laboratory controlled conditions where determining factors such as alertness and vigilance are a constant - remain a mystery to scientists studying the connection between our brains and behaviour.

Holiday sun: a recipe for skin cancer?
But baring all when you've been covered up all year is a recipe for raising the risk of melanoma - a serious form of skin cancer that can spread rapidly. Far better to take it easy in the sun, a new study from the University of Leeds shows. Doctors already know that people with a lot of moles on their skin have a greater risk of getting melanoma than people who hardly have any.
