Switching off a key DNA repair system, Xrcc1 , in the developing nervous system was linked to smaller brain size as well as problems in brain structures vital to movement, memory and emotion in new research.

The study in Nature Neuroscience also provided the first evidence that cells known as cerebellar interneurons are targeted for DNA damage and are a likely source of neurological problems in humans. The cerebellum coordinates movement and balance. The cerebellar interneurons fine tune motor control.

We know how oil and natural gas deposits were created; living organisms died, were compressed, and heated under heavy layers of sediments in the Earth's crust.

Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter.  Now scientists say they have found that ethane and heavier hydrocarbons can be synthesized under the pressure-temperature conditions of the upper mantle; the layer of Earth under the crust and on top of the core.

Researchers at TU Delft have succeeded in measuring the influence of a single electron on a vibrating carbon nanotube.   That can be a real milestone on the road to ultra-small measuring instruments.

Researchers in the Kavli Institute for Nanoscience at TU Delft basically suspended a carbon nanotube, comparable in size to an ultra-small violin string, and then applied an alternating electric field to the nanotube using an antenna.

Metabolic conditions and immunologic conditions rarely coincide but a group of papers appearing in Nature Medicine have linked type 2 diabetes with immunology in an intriguing way. 

In the first study, researchers used two common over-the-counter allergy medications, Zaditor and cromolyn, to reduce both obesity and type 2 diabetes in mice. Zaditor and cromolyn stabilize a population of inflammatory immune cells called mast cells.

In America, there is a debate over 'high risk, high reward' independent research versus Big Science - largescale science projects usually being done by taxpayer funded grants to large universities and basic research primarily being done in the private sector.   Germany tries to have government funding for both and prof. Manfred Bayer from TU Dortmund recently got a $2 million grant to do work in ultrafast acoustics.

Ultrafast acoustics first began to get serious research over 20 years ago at General Motors(1).   The basic concept is that sub-picosecond optical pulses generate longitudinal acoustic pulses with frequencies of 100 GHz and up.    As a thin metal film is hit with alaser pulse, it reacts with a “breathing movement”: it expands and then it contracts.

If you were a linguist, how would you accurately describe 'click' sounds distinct to certain African languages?   It's no easy task but in order to accurately preserve a language like N|uu, which has fewer than 10 remaining speakers (and all over age 60) linguists have to be able to document.

Cornell University professor Amanda Miller and colleagues recently used high-speed, ultrasound imaging of the human tongue to precisely categorize sounds produced by the N|uu language speakers of southern Africa's Kalahari Desert, a step toward understanding the physics of speech production.
