Therefore, food that contains phosphate additives should be labeled, researchers recommend.... Four natural extracts with anti-obesity effects tested on rats - Researchers have identified four plant extracts that might help in preventing and fighting obesity. The researchers identified the most effective plant extracts through in vitro assays; subsequently, extracts were tested on rats. While the results obtained are promising, further studies on animals are required to evaluate and confirm the anti-obesity effects of these extracts. Once their anti-obesity effects are confirmed on animals, the extracts will be tested on humans....

Unpicking HIV's 'invisibility cloak' - Drug researchers hunting for alternative ways to treat human immunodeficiency virus (HIV) infections may soon have a novel target -- its camouflage coat. HIV hides inside a cloak unusually rich in a sugar called mannose, which it uses to slip past the immune system before infecting its host's cells. Recently, however, biochemists discovered a family of chemical compounds that stick strongly to mannose. Understanding how this mechanism works could reveal a way to make drugs adhere to and kill HIV....

Ultrasound study provides first direct evidence of effect of malaria on fetal growth - A study of almost 3,800 pregnancies has provided the most accurate and direct evidence to date that malaria infection reduces early fetal growth. Low birth weight is the most important risk factor for neonatal mortality in developing countries. The research, carried out on the border of Thailand and Myanmar, highlights the importance of preventing malaria in pregnancy....
