Media coverage and threat perception

Popular media coverage of infectious diseases greatly influences how people perceive those diseases, making them seem more dangerous, according to a new study.

Grapes may aid heart risk factors

Research shows that grape intake lowered blood pressure and signs of heart muscle damage, and improved heart function in lab rats - tantalizing clues to the potential of grapes in reducing cardiovascular risk.

Stem cell therapies for heart disease

New research reveals that our bodies' ability to respond to an internal 'mayday' signal may hold the key to success for long-awaited regenerative medicine.

Some cancers need immune response

Tumours that grow around nerves in a rare genetic disease need cooperation from cells from the immune system in order to grow, reports a team of scientists.

Four new suspect Alzheimer's genes

The first family-based genome-wide association study in Alzheimer's disease has identified the sites of four novel genes that may significantly influence risk.

Tiny fungi may have sex while infecting humans

Researchers have proven that microsporidia are true fungi and that this species most likely undergoes a form of sexual reproduction during infection of humans and other host animals.

Bare bones of crystal growth

Scientists report that a hydrophilic peptide, similar in character to those found in calcifying organisms, significantly enhances the magnesium content of calcite.

Biosynthetics production with detours

Scientists at the Helmholtz-Zentrum für Infektionsforschung have achieved an important advance in better understanding metabolic pathways in bacteria and their use.

Novel gene shut-off mechanisms in corn

Scientists have identified unusual differences in the natural mechanisms that silences genes in corn, providing new insight into it protects itself from mutation-causing mobile DNA elements and viruses.

Drinking milk to ease milk allergy?

Giving children with milk allergies increasingly higher doses of milk over time may ease or overcome, their allergic reactions, according to the results of a recent study.

Flu vaccination rates lag for adolescents

Influenza vaccination rates for adolescents who suffer from asthma and other illnesses are still far too low, according to a recent study.

West Nile's spread described

The rapid spread of West Nile virus, a mosquito-borne pathogen, over the past decade is likely to have long-lasting ecological consequences throughout the continent, according to a recent article.

Sarcospan: a little protein for a big problem

Researchers have shown that adding sarcospan, an overlooked and undervalued protein, to muscle cells might ameliorate the most severe form of muscular dystrophy.

Detecting tiny twists with a nanomachine

Nanoscale device may reveal spin-dependent fundamental forces and provide new methods of characterizing torque-generating molecules and DNA strands.

Bacterial clotting depends on clustering

Bacteria can directly cause human blood and plasma to clot-a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research.

Protein-RNA interactions in living cells

Researchers have developed a genome-wide platform to study how specialized proteins regulate RNA in living, intact cells.

Persistent bacterial infection exploits macrophages

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them.

A double-barreled approach for neuroblastoma

Adding an artificial tumour-specific receptor to T-lymphocytes that target a particular virus extended and improved the cells' ability to fight neuroblastoma.

Antioxidants reduce the toxic effects of lead

A research study proves that administering natural antioxidants can reduce the effects of lead poisoning in animals during the gestation and lactation periods.

Computer model improves ultrasound image

A Dutch researcher has developed a computer model that can predict the sound transmission of improved designs for ultrasound instruments.
