Study confirms 2 treatments for AMD provide equal improvements in vision

Two drugs commonly used to treat age-related macular degeneration (AMD) yield similar improvements in vision for patients receiving treatments on a monthly or as-needed basis, according to a study from researchers at the Center for Preventive Ophthalmology and Biostatistics (CPOB) at the Perelman School of Medicine at the University of Pennsylvania. The year-two results of the Compa

Not all altruism is alike, says new study

Not all acts of altruism are alike, says a new study. From bees and wasps that die defending their nests, to elephants that cooperate to care for young, a new mathematical model pinpoints the environmental conditions that favor one form of altruism over another.

Video games can teach how to shoot guns more accurately and aim for the head

Just 20 minutes of playing a violent shooting video game made players more accurate when firing a realistic gun at a mannequin – and more likely to aim for and hit the head, a new study found.

Study shows halting an enzyme can slow multiple sclerosis in mice

Researchers studying multiple sclerosis(MS) have long been looking for the specific molecules in the body that cause lesions in myelin, the fatty, insulating cells that sheathe the nerves. Nearly a decade ago, a group at Mayo Clinic found a new enzyme, called Kallikrein 6, that is present in abundance in MS lesions and blood samples and is associated with inflammation and demy

Molecular spectroscopy tracks living mammalian cells in real time as they differentiate

Knowing how a living cell works means knowing how the chemistry inside the cell changes as the functions of the cell change. Protein phosphorylation, for example, controls everything from cell proliferation to differentiation to metabolism to signaling, and even programmed cell death (apoptosis), in cells from bacteria to humans. It's a chemical process that has long been intensively studied, not

Researchers develop rapid test strips for bacterial contamination in swimming water

Urban beach closures due to coliform outbreaks have become disturbing signs of summer, yet water-testing technology has never been fast enough to keep up with changing conditions, nor accessible enough to check all waters.

Key protein's newly discovered form and function may provide novel cancer treatment target

Research led by St. Jude Children's Research Hospital investigators suggests that safeguarding cell survival and maintaining a balanced immune system is just the start of the myeloid cell leukemia sequence 1 (MCL1) protein's work.

Graduation year drives Facebook connections for college grads

Are you connected to college friends on Facebook? Research from North Carolina State University shows that these social networks tend to form around graduation year or university housing – rather than other interests.

Scientists discover enzyme that could slow part of the aging process in astronauts -- and the elderly

New research published online in the FASEB Journal suggests that a specific enzyme, called 5-lipoxygenase, plays a key role in cell death induced by microgravity environments, and that inhibiting this enzyme will likely help prevent or lessen the severity of immune problems in astronauts caused by spaceflight. Additionally, since space conditions initiate health problems that mimic the agi

Vitamin D supplements may protect against viral infections during the winter

Vitamin D may be known as the sunshine vitamin, but a new research report appearing in the Journal of Leukocyte Biology shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases. Since vitamin D levels decrease during autumn and winter

Electric charge disorder: A key to biological order?

Theoretical physicist Ali Naji from the IPM in Tehran and the University of Cambridge, UK, and his colleagues have shown how small random patches of disordered, frozen electric charges can make a difference when they are scattered on surfaces that are overall neutral. These charges induce a twisting force that is strong enough to be felt as far as nanometers or even micrometers away. These results

Arabic records allow past climate to be reconstructed

Corals, trees and marine sediments, among others, are direct evidence of the climate of the past, but they are not the only indicators. A team led by Spanish scientists has interpreted records written in Iraq by Arabic historians for the first time and has made a chronology of climatic events from the year 816 to 1009, when cold waves and snow were normal.

Scientists identify brain circuitry associated with addictive, depressive behaviors

Scientists at the Gladstone Institutes have determined how specific circuitry in the brain controls not only body movement but also motivation and learning, providing new insight into neurodegenerative disorders such as Parkinson's disease—and psychiatric disorders such as addiction and depression.
