Changes in attention, Gestalt perception linked to healthy aging

When looking at a picture of many trees, young people will tend to say: "This is a forest". However, the older we get, the more likely we are to notice a single tree before seeing the forest. This suggests that the speed at which the brain processes the bigger picture is slower in older people.

National Institute of General Medical Sciences now offers range of online products

As the heat index rises, one thing remains at zero—the cost of the engaging and informative educational materials produced by the National Institutes of Health.

Glucose meters with functional DNA can detect a broad range of targets in a solution

Glucose meters aren't just for diabetics anymore. Thanks to University of Illinois chemists, they can be used as simple, portable, inexpensive meters for a number of target molecules in blood, serum, water or food.

New details about how dendritic cells regulate fate of naive T cells

St. Jude Children's Research Hospital scientists show that the molecule serves as a bridge between the two arms of the immune system that provides a new mechanism guiding T cell differentiation.

Two genetic variations can identify children at higher risk of radiation-induced second cancers

A genome-wide association study published in the August issue of Nature Medicine has found two tiny genetic variations that can predict which patients with Hodgkin's lymphoma are most likely to develop radiation-induced second cancers years after treatment.

Report on versatility of nitric oxide in arming hosts against pathogens

A new target for nitric oxide has been revealed in studies of how it inhibits the growth of Salmonella. This bacterium is a common cause of food-poisoning.

Many doctors do not appropriately offer breast and ovarian cancer counseling

A new analysis has found that many doctors report that they do not appropriately offer breast and ovarian cancer counseling and testing services to their female patients. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study indicates that efforts are needed to encourage these services for high-risk women and discourage them for average-risk women.

First high-resolution genetic maps for African American populations

UCLA life scientists and colleagues have produced one of the first high-resolution genetic maps for African American populations. A genetic map reveals the precise locations across the genome where DNA from a person's father and mother have been stitched together through a biological process called "recombination." This process results in new genetic combinations that are then passed on to the person's children.

Specific yeast protein can promote spontaneous prion formation

It's a chicken and egg question. Where do the infectious protein particles called prions come from? Essentially clumps of misfolded proteins, prions cause neurodegenerative disorders, such as mad cow/Creutzfeld-Jakob disease, in humans and animals.

New method for detecting breast cancer at 'stage 0'

RNL Natural Co., Ltd, a leading biotech company specialized in adult stem cell therapeutics affiliated with RNL BIO Co., Ltd., introduced on June 22, 2011 a new method of detecting breast cancer as early as at 'stage 0' through breath VOCs.

Strategies toxins use to invade human host cells

Toxins produced by plants and bacteria pose a significant threat to humans, as emphasized by the recent effects of cucumber-borne Shiga toxin in Germany. Now, new research published on July 21st by the Cell Press journal Developmental Cell provides a clearer view of the combination of similar and divergent strategies that different toxins use to invade a human host cell.

Sigma Life Science releases breast cancer-specific knockout and knockin cell lines for drug research

Sigma Life Science, the innovative biological products and services research business of Sigma-Aldrich, today announced the expansion of its CompoZr® Oncology Disease Model portfolio with the release of the first in its collection of breast cancer-specific knockout and knockin cell lines for drug discovery and research.

Scientists differentiate brain activity associated with grasping

Quickly grabbing a cup of coffee is an everyday action for most of us. For people with severe paralysis however, this task is unfeasible - yet not "unthinkable". Because of this, interfaces between the brain and a computer can in principle detect these "thoughts" and transform them into steering commands. Scientists from Freiburg now have found a way to distinguish between different types of grasping on the basis of the accompanying brain activity.

Discovery challenges current thinking on origin of malaria parasite

The agent of malaria has been found in the greater spot-nosed monkey, also known as putty-nosed monkey (Cercopithecus nictitans), a small African primate derived from a line different to that of humans, gorillas and chimpanzees.

Myelin regulates key protein involved in sending long-distance signals

The development of a new cell-culture system that mimics how specific nerve cell fibers in the brain become coated with protective myelin opens up new avenues of research about multiple sclerosis. Initial findings suggest that myelin regulates a key protein involved in sending long-distance signals.

Researchers dissociate beneficial and detrimental impacts of maternal regulatory T cells

A normal but concerning consequence of pregnancy is the fact that pregnant women are more susceptible to infection. University of Minnesota Medical School researchers have identified the underlying mechanisms for this physiologic immune suppression that may lead to new therapies to help ward off infections during pregnancy.

Advancements in use of zinc finger nucleases to produce genetically modified pigs

Sangamo BioSciences, Inc. announced the publication of a study demonstrating the use of zinc finger nucleases (ZFNs) to produce genetically modified pigs. The study, which was published in the Proceedings of the National Academy of Sciences (PNAS), represents a significant advancement in the development of improved, less immunogenic animal tissue as a source for transplant into humans.

Combination of strategies reduces more than half the number of tiger mosquitos

The combination of three complementary measures to eradicate tiger mosquitos - avoid having stagnant water, using insecticides to eliminate larvae and adults, and removing rubbish - reduces more than half the number of tiger mosquitos, according to a research coordinated by researchers at Universitat Autonoma de Barcelona.

Humans' desire to kill rats has only made them stronger

Over millennia, mice have thrived despite humanity's efforts to keep them at bay. A Rice University scientist argues some mice have found two ways to achieve a single goal -- resistance to common poison.
