Speed is not a word typically associated with trees; they can take centuries to grow. However, a new study finds evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. The study offers a rare look at how an ecosystem is responding to climate change.
Researchers have made a breakthrough in HIV research that had eluded scientists for over 20 years, potentially leading to better treatments for HIV. The researchers have grown a crystal that reveals the structure of an enzyme called integrase, which is found in retroviruses like HIV. When HIV infects someone, it uses integrase to paste a [...]

Has the almond tree developed a unique way of drawing potential pollinators? A group of researchers in Israel speculate that the toxin called amygdalin that is found in almond tree nectar is in fact an evolutionary development intended to give that tree an advantage over others in its surroundings.
There remains a lack of consensus amongst the medical and scientific communities about any cancer risk from low level radiation, particularly low-dose radiation delivered from computed tomography (CT) scans. However, the study of epigenetics may play a role in determining whether or not future trends of diseases can in fact be linked to utilization of [...]
JPL’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) captured a composite image of the city of Port-au-Prince, Haiti, and the surrounding region on Jan. 27, 2010. This image will be combined with other images of the same area to be acquired later this month and in the future in order to measure the motion of [...]

The most powerful sexual organ, it’s said, is the brain. Now here’s the evidence. New research shows that an overly excitable brain hastens sexual activity in male mice and increases their nervous energy, a finding that not only points to the existence of a central brain mechanism that gives rise to all behaviors but also [...]

The last ancestor we shared with worms, which roamed the seas around 600 million years ago, may already have had a sophisticated brain. Fossils cannot give us this information, but scientists have obtained it by studying small molecules called microRNAs.
Increasing rates of obese and overweight children in the United States may be contributing to a later onset of puberty in boys, say researchers.
