Imaging :: Breaking the nanometer barrier in X-ray microscopy

Argonne National Laboratory scientists in collaboration with Xradia have created a new X-ray microscope technique capable of observing molecular-scale features, measuring less than a nanometer in height. Combining X-ray reflection together with high resolution X-ray microscopy, scientists can now study interactions at the nanometer-scale which often can exhibit different properties. Improving our understanding of interactions at the nanoscale holds promise to help us cure the sick, protect our environment and make us more secure.

Climate :: Climate changes are linked between Greenland and the Antarctic

Even if climate records from Greenland and Antarctic ice cores look different, climate of Artic and Antarctic are directly linked. Investigations of an Antarctic ice core indicate a principle connection between both hemispheres by a “bipolar seesaw.”

Health :: Research shows brain injury may occur within one millisecond after head hits car windshield

Center neurologist shows that brain injury may occur within one millisecond after a human head is thrust into a windshield in a car accident. This happens before any overall motion of the head following impact with the windshield and is a new concept to consider for doctors interested in traumatic brain injury.

Nutrition :: Plant studies reveal how, where seeds store iron

Biologists have learned where and how some plant seeds store iron, a valuable discovery for scientists working to improve the iron content of plants. Their research helps address the worldwide problem of iron deficiency and malnutrition in humans.

Depression :: New treatment strategy for the prevention of recurrent depression

Some patients who experience recurrent depression may benefit from long-term maintenance treatment with anti-depressant medication, according to a new study led by a Virginia Commonwealth University researcher.

DNA :: Penn researcher shows that DNA gets kinky easily at the nanoscale

Physicists from the University of Pennsylvania tackle the fundamental question of how DNA can seemingly violate physics. That is, if DNA is such a rigid molecule, how can it bend and coil without requiring large amounts of force? They used a technique called atomic force microscopy to determine that DNA is much more flexible than previously believed when examined over nano-sized lengths

Eyes :: Funnel in the eye: Signal focusing increases photosensitivity

In poor light the eyes of mice react like some digital cameras: they reduce their resolution while at the same time increasing their sensitivity. Specialists in the retina focus the information of several light sensor cells for this purpose. Scientists from the University of Bonn and their colleagues from Oldenburg, Bochum and Kobe (Japan), have now discovered how all this works. The study will be published on 3 November in the prestigious Journal of Biological Chemistry.

Backache :: Backache beaten by good vibrations?

University of Manchester researchers are recruiting people with backache caused by nerve root pain — commonly known as sciatica — in the first ever study to discover if therapeutic ultrasound can help their condition.

Health :: T-ray breakthrough could make detecting disease far easier

A breakthrough in the harnessing of “T-rays” — electromagnetic terahertz waves — which could dramatically improve the detecting and sensing of objects as varied as biological cell abnormalities and explosives has been announced by a team led by the University of Bath.

HIV :: New way to fight HIV / AIDS

For years researchers have been trying to understand how a few HIV-infected patients naturally defeat a virus that otherwise overwhelms the immune system. Last year, a research team at the University of Rochester Medical Center confirmed that such patients, called long-term non-progressors, maintain higher than normal levels of the enzyme called APOBEC-3G (A3G) in their white blood cells, which function to stave off infections. Now, the same group has teamed up with a structural biologist to provide the first look at the A3G structure. Such information represents an early step toward the design of a new class of drugs that could afford to all the same natural protection enjoyed by few, according to a study published today in The Journal of Biological Chemistry.
