Solving art's mysteries

A team of researchers used advanced imaging technology to colorize a black-and-white photograph of Matisse's 'Bathers by a River', revealing the artist's innovative methods and palette changes. The resulting image shows how Matisse transformed his work from vibrant colors to somber grays, offering insights into his artistic evolution.

Sewage overflow promotes spread of West Nile virus

A study by Emory University found that sewage overflows in urban creeks and streams increase the risk of West Nile virus transmission, particularly in lower-income neighborhoods. The analysis showed a seven times higher risk for residents near affected areas compared to other parts of the city.

The proton -- smaller than thought

Physicists have measured the proton's charge radius with an accuracy of better than one thousandth of a femtometre, significantly deviating from previous measurements. This change affects the Rydberg constant used to calculate energy packets absorbed and emitted by atoms and molecules.

Eating foods rich in vitamin E associated with lower dementia risk

A recent study published in Archives of Neurology found that consuming more vitamin E through the diet is associated with a lower risk of dementia and Alzheimer's disease. The researchers analyzed data from over 5,400 participants and found that those who consumed the most vitamin E had a 25% lower risk of developing dementia.

New discovery in nerve regrowth

Researchers discovered a way to boost nerve growth in peripheral nervous system, offering potential treatments for diabetes and traumatic injuries. Blocking PTEN molecular brake increased nerve outgrowth, providing hope for recovery from nerve damage

Fellowships for outstanding research in drug use and HIV are presented by the International AIDS Society and the National Institute on Drug Abuse at AIDS 2010

The International AIDS Society and National Institute on Drug Abuse have awarded fellowships to seven young researchers from around the world to study the intersection of drug use and HIV. The recipients will receive US$75,000 each to pursue groundbreaking research in biology, epidemiology, public health, behavioral sciences, and more.

A new spin on drug delivery

A new DNA delivery method has been discovered by Virginia Tech chemical engineers, which enhances the delivery of genetic material into cells. The method uses hydrodynamic effects to uniformly deliver DNA over the entire cell surface, resulting in a greatly enhanced transfer of genetic material.

Talking touchscreens aid patients

Multimedia talking touchscreens are helping researchers and clinicians improve communication, knowledge, and adherence to treatment for patients with diverse language skills. The technology provides a more private and accessible way for patients to complete questionnaires and access health information.

Executives who take the fewest risks have the most negative emotions

A Spanish Foundation for Science and Technology study found that executives with higher negative emotional traits took fewer risks, while those with higher educational levels took more. The researchers analyzed data from 70 banks and 46 savings banks, discovering a significant connection between the CEO's emotional traits and firm risk.
