Taste :: Penn researchers discover initial steps in the development of taste

Researchers at the University of Pennsylvania School of Medicine are closer to understanding how the sense of taste develops. They have pinpointed a molecular pathway that regulates the development of taste buds. Using genetically engineered mice, they discovered that a signaling pathway activated by small proteins called Wnts is required for initiating taste-bud formation. They have also determined that Wnt proteins are required for hooking up the wiring of taste signals to the brain.

Nanotechnology :: Consumers neutral on risks, benefits of nano – nanotechnology

The largest, most comprehensive survey of public perceptions of nanotechnology products finds US consumers are willing to use specific nano-containing products — even if there are health and safety risks — when the potential benefits are high. The study also finds US consumers rate nanotechnology as less risky than everyday technologies like herbicides, chemical disinfectants, handguns and food preservatives. The findings appear in December’s issue of Nature Nanotechnology.

Fibroid :: Combined procedure for uterine preservation in treating fibroids

Although fibroids?benign tumors that grow in the uterus?can cause pelvic pain, abnormal vaginal bleeding and infertility, women of childbearing age often choose to forego treatment because the available treatment options don?t guarantee fertility.

Skin Care :: Tea may help heal skin damaged by radiation

Skin damage caused by radiation treatment in cancer patients can be treated with tea extracts and researchers believe that this might be due to anti-inflammatory properties of tea which are extremely beneficial to damaged skin.

Skin Cancer :: Green leafy vegetables reduce skin cancer risk

An 11 year study conducted by the Queensland Institute of Medical Research has concluded that eating leafy greens such as spinach may be as important as wearing sunscreen, protective clothing and a hat in the prevention of skin cancer, highlighting the importance of eating a healthy, well-balanced diet.

Psoriasis :: Glucocorticoid plays key role in skin abnormalities induced by psychological stress

A new study shows how psychological stress induces abnormalities in skin structure and function that could initiate or worsen skin disorders such as psoriasis and atopic dermatitis. The study provides a link for understanding the roles psychological stress and glucocorticoid, a type of steroid, play in skin disorders and shows that blocking glucocorticoid can prevent skin abnormalities induced by psychological stress.

Gene :: Found — the apple gene for red

CSIRO researchers have located the gene that controls the color of apples — a discovery that may lead to bright new apple varieties.

Wheezing :: Infants wheeze less in homes with multiple dogs

Living in a home with multiple dogs may help reduce an infant’s risk for developing wheezing in the first year of life, according to new research from the University of Cincinnati (UC).

Archaeology :: World’s oldest ritual discovered

A new archaeological find in Botswana by an archaeologist from the University from Oslo shows that our ancestors in Africa engaged in ritual practice 70,000 years ago — 30,000 years earlier than the oldest finds in Europe. This sensational discovery strengthens Africa’s position as the cradle of modern man.

Disinfectant :: Solvay’s Perestane effective against Clostridium difficile and MRSA

Perestane?, an innovative biocidal product created and developed by Solvay, has been proven to be an effective disinfectant against Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile. These so-called ?superbugs? may cause fatal diseases, and the treatment of patients with most current antibiotics is ineffective. Researchers from the University of Leeds and Leeds General Infirmary (United Kingdom) have recently demonstrated that disinfectants commonly used in hospitals fail to eradicate Clostridium difficile from the premises, and may even promote spore formation.
