Children With Cancer Risk Fragile Bones
Physicians caring for children with cancer should be on the lookout for signs of bone fragility caused by disease and treatment, according to a new report. True Colors Are In The Brain Of The Beholder
Pictures of brain waves that reveal our ability to see colour could provide a new objective way to diagnose and monitor diseases that affect human color perception. The research finding by a Universiy of New South Wales Ph.D. student, Ms. Mei Ying Boon, has earned her a nomination in this year's Fresh Science Awards. When Less Is More
If technology lives up to its promise, the days of being shackled to your desk on a nice sunny day may be comingto an end. Or will they? Commentary by Tony Long. Herbal Extract As Effective As Commonly Prescribed Anti-depressant
A specially manufactured extract from the herb St John's Wort is at least as effective in treating depression as a commonly prescribed anti-depressant, according to new research published on bmj.com. File-Swap Services Can Be Sued
The Supreme Court, reversing lower court decisions, rules that file-sharing services bear the responsibility for customers who use the software to illegally swap music and movies. Evolution Is Deterministic, Not Random, Biologists Conclude From Multi
Biologists have concluded that developmental evolution is deterministic and orderly, rather than random, based on a study of different species of roundworms. The researchers note that even where we might expect evolution to be random, it is not. Building Better Therapeutic Vaccines For Chronic Infections
Familiar preventive vaccines protect an individual from infections. Therapeutic vaccines, however, are designed for patients who have acquired chronic infections, such as HIV or hepatitis, or even cancers. Thus far, such vaccines have fallen short of expectations. A new study offers details about what may prevent the immune system from responding effectively to a therapeutic vaccine during a state of chronic infection and suggests how scientists might be able to improve the immune response. Multiple Sclerosis Progression Linked To Immune-cell Substance
A new study suggests that a substance made by immune cells plays a key role in the progression of a disease in animals that closely mimics multiple sclerosis (MS). The findings further suggest that blocking the molecule, known as macrophage migration inhibitory factor (MIF) might prevent the progression of the disease. Researchers at The Ohio State University Medical Center conducted the study using mice that develop a disease that mimics MS. Prostate Cancer Survivors Who Suffer From Urinary Incontinence Benefit
A routine check-up for a businessman three years ago revealed prostate cancer. The cancer was caught in time, but a side effect of his successful surgery was "driving him nuts."Losing urine control because of coughing, laughing, sneezing, or lifting is both frustrating and debilitating for the more than 2 million men worldwide afflicted with the condition. Many of these men are prostate-cancer survivors, having undergone surgery for the treatment of their cancer with the often unavoidable outcome of a damaged urinary sphincter. New Compound Effectively Treats Fungal Infections
The human body is home to many different kinds of fungi. While the majority normally do not harm us, some fungi can cause unpleasant infections of skin, nails or lungs. Now scientists have found a new mechanism to attack hard-to-treat fungal infections. They describe how a new compound kills fungal pathogens by blocking an enzyme crucial for their protein synthesis.
