New research indicates that lost memories can be restored, according to new research into a type of marine snail called Aplysia. The findings offer some hope for patients in the early stages of Alzheimer's disease.
Researchers have returned from the first detailed study of the Mariana Trench aboard Schmidt Ocean Institute's research vessel Falkor. The expedition set many new records, including the deepest rock samples ever collected and the discovery of new fish species at the greatest depths ever recorded.
Early developmental exposure to two different antidepressants, Prozac and Lexapro, has been studied by researchers in a mouse model that mimics human third trimester medication exposure. They found that, although these serotonin-selective...Show More Summary
Neutrophils, cells recruited by the immune system to fight infection, need to move through a great variety of tissues. New research shows how neutrophils move through confined spaces in the body. A new system can mimic tissues of different densities and stiffness, enabling improved development and testing of drugs.
Researchers have determined the hospital costs and risk of death for emergency surgery and compared it to the same operation when performed in a planned, elective manner for three common surgical procedures: abdominal aortic aneurysm repair, coronary artery bypass graft and colon resection.

Women whose loved ones are critical of their weight tend to put on even more pounds, says a new study on the way people's comments affect our health. "When we feel bad about our bodies, we often turn to loved ones -- families, friends and romantic partners -- for support and advice. How they respond can have a bigger effect than we might think," said one author.
An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices.
Researchers from the University of Southampton have revealed a breakthrough in optical fiber communications. They developed an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals. Show More Summary
The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to a new article. It is an excellent example that humans and carnivores can share the same landscape, say researchers.
Researchers have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park’s hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus.
A genetic pathway has been found that accounts for the extraordinary size of the human brain. The research team has identified a gene, KATNB1, as an essential component in a genetic pathway responsible for central nervous system development in humans and other animals.
A study has identified the population of white blood cells that tumors use to enhance growth and suppress the disease-fighting immune system. The results mark a turning point in cancer immunology and provide the foundation for developing more effective immunotherapies.
Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has demonstrated that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing.
Misfiring of the brain's control system might underpin compulsions in obsessive-compulsive disorder, according to researchers.
A study of more than 80,000 women has uncovered different risks of developing type 2 diabetes associated with different blood groups, with the biggest difference a 35 percent increased risk of type 2 diabetes found in those with group B, Rhesus factor positive blood compared with the universal donor group O, Rhesus factor negative.
State and local enforcement of federal immigration laws can have an adverse impact on the use of health care services by immigrant Hispanics, according to a new study, which analyzed both birth records and information collected in focus groups and individual interviews.
Scientists are challenging dogma about the transmission of the human immunodeficiency virus type 1 (HIV-1). Most research has focused on infection by free viral particles, while this group of researchers proposes that HIV is also transmitted by infected cells.
Following lung transplantation, resistance to the anti-viral drug ganciclovir may be more likely in cystic fibrosis patients, scientists report. Ganciclovir is given to lung transplant patients to protect against a life-threatening virus...Show More Summary
Endogenous retroviruses play a critical role in the body's immune defense against common bacterial and viral pathogens, researchers have found. Retroviruses are best known for causing contagious scourges such as AIDS, or more sporadically, cancer.
Bacterial infections differ based on distance from the equator and spending on health care, researchers have discovered. In their study, 23 health centers on six continents participated in study of bloodstream infections.
