Contracting white dwarf observed for the first time
Astrophysicists from MSU (Russia) and his colleagues from Italy and Russian Academy of Sciences have found the first observational evidence for a contracting white dwarf. Constant high spin-up rate of a star of this type, located in an enigmatic binary system, can be easily explained if the white dwarf is contracting, the researchers argue. The discovery is reported in the Monthly Notices of the Royal Astronomical Society. (2017-11-14)

Using water and technology to map alcohol's effects on the brain
  • Much of the human body, including the brain, is composed of water.
  • Sophisticated technology called Diffusion Tensor Imaging (DTI) is sensitive to water in the body.
  • Using DTI in a new way, researchers can track water molecules in the brain to examine alcohol's damaging effects on brain white matter.

DTI allows radiologists to see areas of the brain rarely seen using other imaging modalities
Radiologists are now able to look at parts of the brain using diffusion tensor imaging that are rarely visible with any other imaging method, according to a study performed at Beth Israel Deaconess Medical Center in Boston, Mass. (2009-04-23)

(2009-08-10)

Origin of key cosmic explosions still a mystery
When a star explodes as a supernova, it shines so brightly that it can be seen from millions of light-years away. One particular supernova variety -- Type Ia -- brightens and dims so predictably that astronomers use them to measure the universe's expansion. The resulting discovery of dark energy and the accelerating universe rewrote our understanding of the cosmos. Yet the origin of these supernovae, which have proved so useful, remains unknown. (2010-07-12)

Many older brains have plasticity, but in a different place
Brain scientists have long believed that older people have less of the neural flexibility, or plasticity, required to learn new things. A new study shows that older people learned a visual task just as well as younger ones, but the seniors who showed a strong degree of learning exhibited plasticity in a different part of the brain than younger learners did. (2014-11-19)

Fetal heart monitoring ineffective at diagnosing cerebral palsy
Fetal heart monitoring does not identify babies who are diagnosed with white matter brain injury after birth, according to a new study by Johns Hopkins researchers. The study, reported during the Society for Gynecologic Investigation's meeting in Houston, March 24-27, helps explain why the incidence of cerebral palsy in term infants has not changed since the 1960s.
