Scientists Find Trick to 'Disarm' HIV

Without its cholesterol, virus can't harm immune system

(Newser) - A group of US and European scientists have discovered a way to prevent the HIV virus from harming the immune system, in a breakthrough that could lead to an entirely new approach to fighting AIDS. They discovered that by extracting cholesterol, they could render the virus a sitting duck for...

Sex With Neanderthals Boosted Our Immunity

Scientists make 'stunning' discovery in genome comparison

(Newser) - Three years ago, scientists thought humans had never had sex with Neanderthals. Last year, they changed their tune—and now it looks like DNA passed down from Neanderthals has had a “profound impact” on our immune systems. Scientists compared a section of the modern human genome to the same...

British doctors swear the theory is upheld by sophisticated computer models: The male immune system is underdeveloped compared to the female because men are...

Vitamin D Found to Boost Immunity

New study discovers that 'sunshine vitamin' activates T-cells

(Newser) - Taking in some sunshine is vital for your immune system, according to a new study released yesterday. A group of Danish researchers have discovered that infection-killing T cells rely on vitamin D to activate, Reuters explains. “If the T cells cannot find enough vitamin D in the blood, they...

Exercise Curbs Colds, Even Cancer

Moderate, regular activity is like a 'drug' that boosts immune system

(Newser) - Some benefits of exercise are less visible than weight loss and muscle mass, but no less tangible. In fact, the most awesome effects of physical activity are measured by what doesn’t happen: A brisk walk five times a week has been shown to ward off respiratory infections, and regular...

P&G Recalls Contaminated Vicks Nasal Spray

Lots affected by bacteria were sold in US, UK, Germany

(Newser) - Procter & Gamble has voluntarily recalled batches of its Vicks nasal spray contaminated with bacteria. Though the bacteria are likely harmless to healthy people, CNN reports, the contamination could prove disastrous for those with compromised immune systems.

Our Immune System Already Prepared for Swine Flu

Disease isn't as contagious, deadly as feared

(Newser) - The initial fear that swine flu is a totally new virus that your immune system isn’t equipped to handle turns out to be pure hype. According to a new study, immune systems that have previously had contact with flu viruses recognize H1N1 and deal with it the same way,...

Some 67% of sufferers...

Breakthrough Raises Hope for HIV Vaccine

Antibodies could help scientists combat elusive virus' defenses

(Newser) - Researchers have found two antibodies that neutralize the AIDS virus more successfully than any identified in the past, resurrecting hopes that it may be possible to develop an effective vaccine, Time reports. The new antibodies are effective against a broad range of HIV variants, neutralizing the virus’ most effective defense:...

Image Rehab: Appendix Is Good for Something After All

Long-neglected organ is far from useless, researchers say
