Doctors said a London man with HIV has become the second known adult in the world to be apparently cleared of the infection since the global epidemic began decades ago, giving hope for a potential cure for AIDS. Doctors said that recent tests showed no trace of the man’s previous HIV infection. The milestone came about three years after the man received bone marrow stem cells from an HIV-resistant donor and about a year and a half after coming off antiretroviral drugs. The patient was receiving the bone marrow transplant for cancer. The case offers hope that researchers will soon find a cure for AIDS. But doctors cautioned against calling the patient’s results a cure for HIV, the virus that causes AIDS.

World on Fire Global Warming

Earth just had its 2nd-warmest October on record, according to NOAA data released Tuesday. NASA reported the same finding last week. The finding extends the planet's hot streak to 406 straight months with temperatures above the 20th century average. Meanwhile, the last colder-than-average month occurred in February 1985. This means that no one under the age of 32 has ever experienced a cooler-than-average month on this planet.

otto warburg lab 

In the early 20th century, the German biochemist Otto Warburg believed that tumors could be treated by disrupting their source of energy. His idea was dismissed for decades — until now. Born in 1883 into the illustrious Warburg family, Otto Warburg was raised to be a science prodigy. His father, Emil, was one of Germany’s leading physicists, and many of the world’s greatest physicists and chemists, including Albert Einstein and Max Planck, were friends of the family.

reduced Immune System

In the last half-century, the prevalence of autoimmune disease — disorders in which the immune system attacks healthy tissue in the body — has increased sharply in the developed world. Our bodies are confused by this 21st-century world.An estimated one in 13 Americans has one of these often debilitating, generally lifelong conditions. Many, like Type 1 diabetes and celiac disease, are linked with specific gene variants of the immune system, suggesting a strong genetic component. But their prevalence has increased much faster — in two or three generations — than it's likely the human gene pool has changed.

The few residents of the burned-out Northern California city of Paradise who were able to inspect their property on Saturday saw nothing but disappointment. Nearly the entire city of 27,000 residents lay in ruins and most were still barred from returning to the still hazardous town where small fires continued to flare. Butte County Sheriff Kory Honea said Saturday 14 additional bodies were found, bringing the death toll to 23. The victims have not been identified. Two people were found dead in a wildfire in Southern California, bringing the total number of fatalities for the state to 25.
