10% weight loss in obesity with green coffee beans extract
Green, or unroasted, coffee beans can produce a substantial decrease in body weight in a relatively short period of time, revealed by researchers in a study presented at the 243rd National Meeting & Exposition of the American Chemical Society (ACS).

Popcorn contains more antioxidant than fruits and vegetables
Popcorn contains more of the healthful antioxidant substances called "polyphenols" than fruits and vegetables. The hulls of the popcorn –– the part that everyone hates for its tendency to get caught in the teeth –– actually has the highest concentration of polyphenols and fiber.

Eating grapes and drinking red wine protect your skin
UV radiation leads to the generation of reactive oxygen species (ROS). These molecules exert a variety of harmful effects by altering key cellular functions and may result in cell death. Several studies have demonstrated that human skin can be protected against UV radiation by using plant-derived antioxidants.

A better imaging agent for heart disease and breast cancer
Scientists are reporting development of a process for producing large quantities of a much-needed new imaging agent for computed tomography (CT) scans in heart disease, breast cancer and other diseases, and the first evidence that the material is safe for clinical use.

Frog skin secretions may provide best antibiotics
Frog skin contains natural substances that could be the basis for a powerful new genre of antibiotics, revealed by researchers.

Black rice a source of healthful antioxidants
Health conscious consumers who hesitate at the price of fresh blueberries and blackberries, fruits renowned for high levels of healthful antioxidants, now have an economical alternative, scientists reported here today at the 240th National Meeting of the American Chemical Society (ACS).

Bottled tea beverages contain no healthful antioxidants
Many commercially bottled tea beverages contain little or no healthful antioxidants, new research suggests. The first measurements of healthful antioxidant levels in commercial bottled tea beverages has concluded that health-conscious consumers may not be getting what they pay for: healthful doses of those antioxidants, or "poylphenols," that may ward off a range of diseases.

Advance toward earlier detection of melanoma
Scientists are reporting development of a substance to enhance the visibility of skin cancer cells during scans with an advanced medical imaging system that combines ultrasound and light.

New form of insulin Afrezza can be inhaled
Scientists described a new ultra-rapid acting mealtime insulin (AFREZZA™) that is orally inhaled for absorption via the lung. Because the insulin is absorbed so rapidly, AFREZZA's profile closely mimics the normal early insulin response seen in healthy individuals.

Walnuts may help fight prostate cancer
Scientists in California are reporting for the first time that walnuts - already renowned as a rich source of omega-3 fatty acids that fight heart disease - reduce the size and growth rate of prostate cancer in test animals.

Testosterone deficiency affects male cancer survivors' quality of life
A new study has found that many male cancer survivors who develop testosterone deficiency after receiving chemotherapy or radiation therapy have an impaired quality of life and reduced energy levels.

Green tea may help fight glaucoma and other eye diseases
Scientists have confirmed that the healthful substances found in green tea - renowned for their powerful antioxidant and disease-fighting properties - do penetrate into tissues of the eye.

Copper may lead to Alzheimer's disease in older
A new study linked high levels of copper and iron to Alzheimer's disease, heart disease, and other age-related disorders. The report is published in ACS' Chemical Research in Toxicology.

Blueberry juice improves memory in older adults
Scientists are reporting the first evidence from human research that blueberries - one of the richest sources of healthful antioxidants and other so-called phytochemicals - improve memory.

Food aromas may prevent overeating helping obese
A real possibility does exist for developing a new generation of foods that make people feel full by releasing anti-hunger aromas during chewing, scientists in the Netherlands are reporting after a review of research on that topic.

Fast, accurate urine test for pneumonia
Scientists are reporting a discovery of the potential basis for a urine test to diagnose community-acquired pneumonia (CAP), a difficult-to-diagnose disease that is the sixth leading cause of death in the United States.

Hepatitis B hits men harder than women due to an abnormal protein
Researchers are trying to explain the long-standing mystery of why the hepatitis B virus (HBV) sexually discriminates -- hitting men harder than women.

Pumpkin skin may scare away germs, infections
Pumpkin skin contains a substance with an antibacterial effect against microbes that cause millions of cases of yeast infections in adults and infants each year.

Oxycholesterol cholesterol may pose greatest heart disease risk
Health-conscious people know that high levels of total cholesterol and LDL cholesterol (the so-called "bad" cholesterol) can increase the risk of heart attacks.

Popcorn has highest levels of healthy antioxidants
Snack foods like popcorn and many popular breakfast cereals contain "surprisingly large" amounts of healthful antioxidant substances called "polyphenols", revealed by researchers at the 238th National Meeting of the American Chemical Society (ACS).

Microneedle patch would replace injections and needles
An array of microneedles could be coated with medicine and act as a painless drug delivery system for flu vaccines, diseases of the eye and more, revealed by researchers.

Dietary supplement carnosine may help prevent cataract
The popular dietary supplement carnosine may help to prevent and treat cataracts, revealed by researchers. Cataract a clouding of the lens of the eye that is a leading cause of vision loss worldwide.

Skin odor may diagnose skin cancer
Chemists described the first identification of a specific "odor profile" for skin cancer, a discovery that could form the basis of a rapid, non-invasive test for diagnosing the most common type of cancer in the United States.

Avoid grapefruit juices when taking certain drugs
Grapefruit and other common fruit juices, including orange and apple, decrease the absorption of drugs, potentially wiping out their beneficial effects.
