Scientists find significant correlations between East Asian dust events and chlorophyll a concentration not only in the open ocean of North Pacific Ocean, but also in the Chinese marginal seas.
New research has identified the role of a specific protein in the human body that can help prevent the survival and spread of eye cancer, by initiating cancer 'cell-suicide.'
All cells have surface membranes and maintaining the surface area of this membrane is critical to the normal functioning of cells. The surface membranes of cells lining our lungs, guts and the light-sensing cells of our eyes undergo constant recycling to operate effectively. Using the light-sensitive membranes in fruit fly eyes as a model system, have recently identified an enzyme named Phospholipase D or PLD -- that is essential for recycling of membranes for normal sight.
In order to guide us accurately through space, the brain needs a 'sense' of the speed of our movement. But how do such stimuli actually reach the brain? Researchers have now identified a signal pathway in mice that feeds speed information directly into the brain's navigation system.
Researchers have published the first demonstration of humans playing a simple, two-dimensional computer game using only input from direct brain stimulation -- without relying on any usual sensory cues from sight, hearing or touch.
A new study shows a huge US market for plug and play solar energy, with billions of dollars in retail sales and energy savings. So what's holding up widespread use?
Certain personality traits – such as disinhibition (a lack of restraint) and impulsivity – increase the chances of developing alcohol use disorders (AUDs), new research shows.
A metabolic pathway linked to slower aging is overactive in a deadly form of brain cancer, according to researchers. Their findings suggest that tweaking the pathway to treat cancer may affect other biological processes, such as aging.
The combination of two new drugs that harness the body’s immune system is safe and effective, destroying most cancer cells in 64 percent of patients with recurrent Hodgkin lymphoma, according to the results of an early-phase study.
In honey bee colonies, a single queen is laying eggs from which thousands of worker bees are born. At a young age, workers care for the brood, then build and defend the nest and eventually, towards the end of their lives, leave the safety of the nest to forage for food. This major step in their lives is speeding up ageing because searching the environment for food exposes these foragers to a wide range of stressors, such as pathogens, predators and adverse weather conditions.
Researchers have demonstrated in animal models that a protein called NLRP2 plays an important role in early embryogenesis, the process of cell division in fertilized eggs that occurs before they implant into the lining of the uterus. In addition, the protein was shown to become more important with increasing maternal age, as blocking NLRP2 in eggs prevented them from developing in blastocysts. As a similar protein exists in humans, these insights may lead to greater understanding of reproductive disorders and novel paths to treatment, report investigators.
Agave – the cactus-like plant which forms the base ingredient of tequila – has a nocturnal ‘body clock’ which allows it to ‘breathe’ at night and withstand the driest of conditions, new research has shown.
A team of scientists shows changes in the immediate environment of DNA after the ovum and sperm fuse to form the zygote. The results suggest why all conceivable somatic cells can develop from the germ cells.
A common class of drugs for vision loss may actually add to the problem in some patients, according to new research.
Promising results have been announced from an early trial in which patients with high-risk acute myeloid leukemia received genetically engineered immune cells. Of the 12 AML patients who received this experimental T-cell therapy after a transplant put their disease in remission, all are still in remission after a median follow-up of more than two years.
A research team has confirmed expectations of higher healthcare utilization and costs with relapsed Diffuse Large B-Cell Lymphoma (DLBCL).
Female lemurs with normal color vision, as well as their cohabitating colorblind group members, may have selective advantage over lemur groups whose members are all colorblind, according to anthropologists.
Seven common moisturizers would be cost effective in preventing eczema in high-risk newborns, research shows. By using the cheapest moisturizer in the study (petroleum jelly), the cost benefit for prophylactic moisturization was only $353 per quality-adjusted life year – a generic measure of disease burden that assesses the monetary value of medical interventions in one’s life.
New LED lights that are being installed in milk display cases across the country do more than just reduce energy bills -- they also help milk taste better, researchers have found.
Americans are split on getting an annual flu shot, with four out of 10 having done so in the past year and around half saying they had already received or were planning to get the vaccine this year, according to new national survey data.
