Neuroscientists find human brain can process entire images that eye sees for 13 milliseconds

Imagine seeing a dozen pictures flash by in a fraction of a second. You might think it would be impossible to identify any images you see for such a short time.

Researchers develop "smart" hydrogel that can deliver medicine on demand

Researchers at the University of Delaware have developed a "smart" hydrogel that can deliver medicine on demand, in response to mechanical force.

Research shows how coevolution between humans and bacteria can affect gastric cancer risk

Research carried out in two distinct communities in Colombia illustrates how coevolution between humans and bacteria can affect a person's risk of disease. Working with colleagues in Columbia and the U.S., Scott Williams, PhD, a professor of genetics at the Geisel School of Medicine at Dartmouth, and his graduate student Nuri Kodaman discovered that the risk of developing gastric cancer depends heavily on both the ancestry of the person and the ancestry of Helicobacter pylori with which that person is infected.

New study examines factors that may lead to end stage renal disease

About 33 percent of people with type 2 diabetes suffer kidney damage that progresses to end stage renal disease, at which point they require either dialysis or kidney transplantation. Scientists have thought that this kidney disease is driven by damage to the glomeruli, blood vessels in the kidney, which spill the protein albumin into the urine. Current treatments targeting the resulting "albuminuria" do not prevent kidney failure.

International study develops refined method to identify individuals at risk for certain inherited cancer

An international study has developed a refined method to identify people at risk for certain inherited cancer as a result of Lynch syndrome.

PGC-1α protein found in muscle may contributes to the development of type 2 diabetes later in life

A Montr-al research team led by Jennifer Estall at the IRCM discovered that a protein found in muscle tissue may contribute to the development of type 2 diabetes later in life. The study's results, published in today's printed edition of the scientific journal American Journal of Physiology - Endocrinology and Metabolism, indicate that the protein could be a promising early predictor of increased diabetes risk.

New stem cell study explains how breast cancer spreads

Breast cancer stem cells exist in two different states and each state plays a role in how cancer spreads, according to an international collaboration of researchers. Their finding sheds new light on the process that makes cancer a deadly disease.

Research identifies new way for slow release drugs

Reservoirs of pharmaceuticals could be manufactured to bind specifically to infected tissue such as cancer cells for slow, concentrated delivery of drug treatments, according to new research published in ACS Macro Letters.

BMH-21 chemical compound has ability to shut down a common cancer process

Johns Hopkins scientists say a previously known but little studied chemical compound targets and shuts down a common cancer process. In studies of laboratory-grown human tumor cell lines, the drug disrupted tumor cell division and prevented growth of advanced cancer cells.

Cedars-Sinai investigators identify new molecular abnormalities in diabetic cornea

Investigators at the Cedars-Sinai Regenerative Medicine Institute have identified new molecular abnormalities in the diabetic cornea that could contribute to eye problems in affected patients. With this new knowledge, investigators aim to accelerate the process of healing and repair in damaged corneas to ultimately reverse the effects of diabetes-induced eye complications.

New gold nanoparticle method allows for tracking studies of virus pathways in tissues

Enteroviruses are pathogenic viruses infecting humans. This group consists of polioviruses, coxsackieviruses, echoviruses and rhinoviruses. Enteroviruses are the most common causes of flu, but they also cause serious symptoms such as heart muscle infections and paralysis. Recently, enteroviruses have been linked with chronic diseases such as diabetes.

Breast cancer cells masquerade as neurons begin to form ultimately-deadly brain tumors

Treatment and "cure" of breast cancer doesn't ensure that the disease won't spread to the brain. Too often, sometimes years after an initial diagnosis and remission, breast cancer cells are discovered growing as new tumors within the brain. Now City of Hope researchers have found how this happens.

Researchers look at age-related differences on how memories are stored and retrieved

It's not that younger people are able to remember more than older people. Their memories seem better because they are able to retrieve them in higher definition. So says Philip Ko of Vanderbilt University in the US, in a study that sheds light on how differences in the behavioral and neural activity of younger and older adults influence the different generations' ability to store and recall memories.

New system allows us to power our devices long after sun goes down

Solar energy has long been used as a clean alternative to fossil fuels such as coal and oil, but it could only be harnessed during the day when the sun's rays were strongest. Now researchers led by Tom Meyer at the Energy Frontier Research Center at the University of North Carolina at Chapel Hill have built a system that converts the sun's energy not into electricity but hydrogen fuel and stores it for later use, allowing us to power our devices long after the sun goes down.

Less gray matter in brain not linked to reading disabilities in people with dyslexia

In people with dyslexia, less gray matter in the brain has been linked to reading disabilities, but now new evidence suggests this is a consequence of poorer reading experiences and not the root cause of the disorder.

Presence of gene variant in people with MCI associated with accelerated rates of brain atrophy

The presence of a gene variant in people with mild cognitive impairment is associated with accelerated rates of brain atrophy, according to a new study published online in the journal Radiology.

Research reveals new therapy for preventing production of sphingolipids by lymphoma cells

Christopher Parsons, MD, Director of the HIV Malignancies Program at LSU Health Sciences Center New Orleans, is the senior author of a paper that is the first to report that specialized fat (lipid) molecules, called sphingolipids, play a key role in the survival of aggressive lymphomas caused by viruses.

Brain's structure is related to how intensely people perceive pain, say scientists

Everybody feels pain differently, and brain structure may hold the clue to these differences. In a study published in the current online issue of the journal Pain, scientists at Wake Forest Baptist Medical Center have shown that the brain's structure is related to how intensely people perceive pain.
