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.
