Yet another study has revealed that more time spent on social media translates into higher rates of depression especially among young girls. The new study reveals that girls are worst affected by depression due to poor sleep and online bullying compared to boys. The results of the study were published in the journal EClinicalMedicine , published by the Lancet .

Research from the University of Michigan Life Sciences Institute has uncovered a cause of declining motor function and increased frailty in tiny aging worms—and a way to slow it down. The findings, scheduled to publish in Science Advances, identify a molecule that can be targeted to improve motor function and indicate that similar pathways may be at play in aging mammals as well.
The American Academy of Neurology (AAN) called for uniform brain death laws, policies, and practices in a new position statement. The position paper, published in Neurology , defines brain death – otherwise known as death by neurological criteria – as the individual's death due to irreversible loss of function of the entire brain in accordance with the Uniform Determination of Death Act (UDDA), model state law that was approved for the US in 1981.
Applying physics to the properties and underlying structures of the molecules of life offers an insight into the mechanisms that make living beings tick. But even seemingly simple actions like muscle contraction involve a wide array of biological interactions, which has shrouded the dynamics and function of individual molecules behind a curtain of complexity.
A giant toadstool that swallow up vitamins and nutrients in the intestines and kidneys. This is how the receiver, which absorbs B12 vitamin in the small intestine, looks. For the first time, researchers have had an insight into an unknown biology which has survived hundreds of millions of years during the evolution of life.
Researchers are developing the self-contained planters that will allow astronauts to grow food in space. Fresh food is so attractive to astronauts that they toasted with salad when they were able to cultivate a few lettuce heads on the International Space Station three years ago.
Researchers at Sahlgrenska Academy at the University of Gothenburg, Sweden, in collaboration with research groups in Finland, Canada, and Slovenia, have discovered a novel and unexpected function of nestin, the best known marker of neural stem cells.
One of the important and predicted physiological effects of spinal anesthesia is hypotension. A range of strategies including mechanical interventions, intravenous fluids and vasoconstrictor drugs have been used to minimize or prevent spinal anesthesia-induced hypotension.
Observational studies suggest that ondansetron reduces the incidence of post-spinal hypotension (PSH) and support the use of combined fluid preloading and vasoconstrictors for this purpose (but with limited doses) to avoid side effects as fluid overload and tachycardia respectively.
