Chocolate shot with a heart

Buhler Bindler will present its revolutionary new "FlexiShot" chocolate molding system at the Interpack in Dusseldorf.

Antibiotics paradox

While consumers are increasing demand for pork produced without antibiotics, more of the pigs raised in such conditions carry bacteria and parasites.

Electrical discharge in the brain

After a stroke, even unaffected areas of the brain are at risk – depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain. If these waves are repeated, more cells die.

Perfecting a solar cell

New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost.

Menopausal brain change

Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don't notice can be more dangerous.

Organ rejection culprit identified

When a mouse's immune system is deciding whether to reject a skin graft, one powerful member of a molecular family can help the graft survive.

ALS protein in brain extensive

TDP-43 accumulates throughout the brain, suggesting ALS has broader neurological effects than previously appreciated and treatments need to take into account more than motor neuron areas.

Medicines derived from cannabis

Researchers determined that medical use of cannabinoids do not cause an increase in serious adverse events, but are associated with an increase in some non-serious adverse events.

Scientist Spotlight: Sanford Simon

Researchers became the first scientists to see HIV forming and budding in real time. Scientist Live spoke with Dr. Simon about seeing the virus assemble.

Gene variant health risk

Nutrition researchers have identified five common genetic variations that increase the risk of metabolic syndrome, a group of factors linked to heart disease and diabetes.

Grape seeds treats Alzheimer's

Mount Sinai researchers have discovered that polyphenolics derived from red grape seeds may be useful agents to prevent or treat Alzheimer's disease.

Inherited melanoma risk

When people know the results of genetic tests confirming they have inherited an increased risk of developing melanoma, they follow skin cancer screening recommendations more proactively.

Mutation benefits drug effect

A new study shows that a mutation present in some cases of acute leukemia makes the disease more susceptible to high doses of a particular anticancer drug.

Tracking Prions

Scientists have examined two different forms of a prion-forming protein domain by means of NMR spectroscopy and report that the infectious and non-infectious forms differ.

Lifestyle alters gene activity

A Finnish study of identical twins has found that physical inactivity and acquired obesity can impair expression of the genes which help the cells produce energy.

Hormones lead to killing

Biologists have linked the murderous behaviour of the Nazca booby to high levels of testosterone and other male hormones found in the hatchlings.

Gene increase in evolution

The newly sequenced genome provides the best evidence yet that vertebrates evolved over the past 550 million years through a four-fold duplication of the genes of more primitive ancestors.

Bacteria anticipate changes

A new study by Princeton University researchers shows for the first time that bacteria don't just react to changes in their surroundings -- they anticipate and prepare for them.

Protons partnering neutrons

Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment.

Psychosocial issues and AIDS

Psychosocial influences such as stress have been neglected in biomedical and treatment studies involving people infected with HIV, yet they are now known to have significant health impacts.
