Scientists have a new theory as to why a woman’s fertility declines after her mid-30s: As women age, their egg cells become riddled with DNA damage and die off because their DNA repair systems wear out. Defects in one of the DNA repair genes, BRCA1, have long been linked with breast cancer and now also appear to cause early menopause.

Researchers have reversed behavioral and brain abnormalities in adult mice that resemble schizophrenia by restoring normal expression to a suspect gene, Neuregulin 1, that is over-expressed in humans with the illness. Targeting Neuregulin 1, which makes a protein important for brain development, may hold promise for treating at least some patients with the brain disorder, say the scientists.

Like patients with schizophrenia, adult mice biogenetically-engineered to have higher Neuregulin 1 levels showed reduced activity of the brain messenger chemicals glutamate and GABA. The mice also showed behaviors related to aspects of the human illness. For example, they interacted less with other animals and faltered on thinking tasks.

When a magnet is divided, a new magnet with north and south poles is always created. A monopole, i.e. a north pole without a south pole or a south pole without a north pole has not yet been discovered but in Science researchers describe the discovery of new type of artificial monopole in a solid, i.e. particles, which have similar characteristics to monopoles, but which only exist within materials.  

Can climate change be mitigated without hurting the quality of life of people? 

Food and basic necessities are met before culture and other aspects. Thinking among environmentalists is that if agriculture intensifies in a particular region, it would have an impact on the water sector due to irrigation use, meaning less water for domestic, industrial or environmental needs. Knowing that, they believe that by setting variables such as temperature, rainfall or irrigation’s efficiency, it is possible to predict how maize yields will be affected by these changes and have created a new projection tool.  

If Martians wanted to vacation some place exotic, they might pick the Redwood forests of the Pacific, yet if they wanted to feel like they were at home, but with better hotels, a researcher has determined the best analogue of Mars.

Australia.

Associate Professor Patrice F. Rey (University of Sydney) has recently outlined attributes suggesting that the Australian red center could be a close analogue for the surface of the red planet – and how this unusual weathering has led to the formation of Australia’s opals.

The U.S. Department of Energy has approved a Small Business Innovative Research (SBIR) Phase 1 grant proposal for $149,900 to study the differential data from retrofitting a concentrated solar thermal array to the existing geothermal electrical generation system currently installed at the Oregon Institute of Technology (OIT) in Klamath Falls Oregon.

Marc Rappaport of Rappaport Energy Consulting LLC, Ridgefield, WA wrote the proposal with the assistance of Don Jeter, P.E. of Eagle Engineering&Testing Services of Bellingham, WA, and Tanya Boyd of the Oregon Institute of Technology, Geo Heat Center.
