Millions of children, as many as 2% of all births in the U.S. and Europe, have been born to couples with fertility problems through assisted reproductive techniques such as in vitro fertilization (IVF). Because it is a newer field, relatively little research has been conducted to evaluate the long term effects of assisted reproductive techniques. 

Research presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB) says that assisted reproductive techniques alter the expression of genes that are important for metabolism and the transport of nutrients in the placenta of mice. 
Abandoned mine shafts could be used to provide geothermal energy to local towns, say two engineers from the University of Oviedo in the journal Renewable Energy. They say the method they have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide.

Rafael Rodríguez, from the Oviedo Higher Technical School of Mining Engineering and colleague María Belarmina Díaz have developed a "semi-empirical" method (part mathematical and part experimental) to calculate the amount of heat that could be produced by a mine tunnel that is due to be abandoned, based on studies carried out while it is still in use.
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.
