General Anesthetic Induces Slow Oscillations, Disrupts Brain Communication

patient-general-anesthesia

Little is known about general anesthetics, the drugs that put patients in a coma-like state, feeling no pain or discomfort while being operated on. A new study shows that these classes of drugs change the activity of a specific region of the brain and make it more difficult for the parts to communicate. The scientists […]

Blind Mole Rats May Hold Cellular Clues to Effective Treatments for Cancer

palestine-mole-rat

New cell cultures from two species of blind mole rats, Spalax judaei and Spalax golani, behave in ways that render them impervious to the growth of tumors. The scientists published their findings in the journal PNAS. Vera Gorbunova, from the University of Rochester in New York, and her colleagues have shown that the rodents have […]

Exploring Chemical Changes at the Molecular Scale

ultrabright X-ray laser pulses can reveal details of chemically important molecules

Using X-ray emission spectroscopy, a team of researchers reveal chemical information about molecules before they are destroyed. Research at SLAC National Accelerator Laboratory demonstrates that ultrashort, ultrabright X-ray laser pulses can reveal details of chemically important molecules at room temperature and in their natural state. The technique could aid studies of photosynthesis and industrial catalysts, […]

The Brightest Flare Ever Observed from Sagittarius A*

sagittarius-A-flare-black-hole

The supermassive black hole at the center of the Milky Way, Sagittarius A*, emits relatively little energy for its size, as much energy as Sol even though it’s 4 billion times as massive. Astronomers have observed that nearly once a day, the black hole emits a brief burst of light before settling down. It’s yet […]

Scientists Change the Color of Gold

nano-fabrication-unit

Scientists in Southampton, UK, are now able to change the color of gold, which could have applications in jewelry-making and security features. The scientists published their findings in the Journal of Optics. The technique used by the scientists involves embossing tiny raised or indented patterns on the metal’s surface, altering the way that it absorbs […]

Antidepressant Use During Pregnancy Has Increased Risks

Study Links Pregnancy Risks with Antidepressants

HMS researchers at Beth Israel Deaconess Medical Center examined the current literature on the safety and efficacy of selective serotonin reuptake inhibitor (SSRI) use in infertile women, finding that antidepressant use during pregnancy is associated with increased risks of miscarriage, birth defects, preterm birth, newborn behavioral syndrome, persistent pulmonary hypertension of the newborn and possible […]

12 Billion-Year Old Supernova Discovered by Astronomers

superluminous-supernova

Astronomers have discovered a pair superluminous supernovae, which are more than 10 billion years old. The Universe was only 3.75 billion years old back then. Of the pair, one is more remote and ranks as the most distant supernova ever discovered. Astronomers used two telescopes atop Mauna Kea in Hawaii to find these supernovae, and […]

Hopping Robots Could Use Stutter Jump to Conserve Energy

test-robot-stutter-jump

Jumping is much more complicated that it might seem, at least for robots. A new study indicates that the range of future rescue and exploration robots could be extended by adopting a two-part stutter jump. The researchers published their findings in the journal Physical Review Letters. This technique entails in taking a short hop before […]

Synthetic Antioxidant Suppresses Symptoms of Huntington’s Disease in Mice

Huntington's disease mouse model

A team of scientists have designed a synthetic antioxidant, XJB-5-131, that targets mitochondria and suppresses symptoms of Huntington’s disease in mice. There’s new hope in the fight against Huntington’s disease. A group of researchers that includes scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses […]
