Space debris orbiting the earth is becoming increasingly hazardous, researchers warn, with junk posing increasing danger to astronauts and space missions.

A study from the American Academy of Sleep Medicine found that the average U.S. worker suffering from insomnia loses 11.3 days each year in productivity.

U.S. Tennis star Venus Williams withdrew Wednesday from the U.S. Open after recently being diagnosed with an energy-draining autoimmune disease called Sjogren's syndrome.

Swiss researchers were able to create micron-sized water droplets by shooting laser beams into the sky, a process that may be a precursor to actually stimulating rainfall.

Tropical Storm Katia is now a Category 1 hurricane, but its impact on the United States, if any, remained unclear as it continued to strengthen on Thursday.

Venus Williams was forced to withdraw from the U.S. Open on Wednesday after being diagnosed with Sj?gren's syndrome, leaving fans wondering: what is that, and is it serious? Here are five things you should know about the condition.

A recent study finding by biologists at the University Of Southern California (USC) might help to explain why humans lose energy with age. One benefit of the study would lead to pathways for developing medicine, new diets or pharmaceuticals that might help to slow the aging process. In the new study, USC scientists have revealed that as human cells grow older, there is a greater decline in the availability of an enzyme, called Lon protease.

Antibiotic resistance is a problem that dates back 30,000 years according to a recent discovery.

Scientists say producing hydrogen in the backyard could be possible in future by tweaking an inexpensive semiconductor material, which could be available in commercial store, for generating hydrogen from water by using sunlight.

The clinical trial of injecting stem cell into the brains of three patients as part of treatment of stroke was successful, according to a British biotech company behind the trial.

NASA's Chandra X-ray Observatory has discovered a pair of supermassive black holes in a spiral galaxy similar to the Milky Way. Located approximately 160 million light years from Earth, the pair is the nearest known such phenomenon.

Subsequent to two days of debates and testimonials, Food and Drug Administration said that silicone breast implants are safe.

Extreme thinness may not be only about dieting or exercise. Scientists have identified a genetic cause for extreme thinness, according to a study published on Aug. 31 in the journal Nature. The research shows that people with extra copies of certain genes are much more likely to be very skinny.

A set of new still images collected by NASA's Hubble Space Telescope show in unprecedented detail the jets of glowing gas ejected from young stars, providing a peek at how the sun came into existence.

Silicone-gel breast implants are safe and effective, according to the U.S. Food and Drug Administration.

The green anole lizard, also known as Anolis carolinensis, is the first non-bird species of reptile to have its genome sequenced and assembled. Researchers said the new clues that have emerged from the full sequencing of the lizard's genome may offer some insight into how the genomes of humans, mammals, and other reptiles have evolved.

Global warming and climate change are phenomena that broke the bonds of scientific circles to emerge as a matter of debate between believers and skeptics. Countless studies validating and denying global warming have seen the light of the day, providing fodder for more, often somewhat bitter debates. Within the past month, Nobel Prize winner and leading climate change alarmist Al Gore has called those who deny global warming akin to racists, and pseudo-...

Hurricane Irene devastated East Coast and New York, and now a wildfire caused by drought is affecting North Texas and Oklahoma City.

Tropical Storm Katia strengthened into a hurricane over the Atlantic Wednesday, while another mass of thunderstorms that could become a named storm this week triggered evacuations of some oil workers from the Gulf of Mexico.

Astronomers have combines years of still images collected by NASA's Hubble Space Telescope to create movies that reveal never-before-seen details about the stellar birthing process. The movies show energetic jets of glowing gas being expelled from young stars and sheds light on the formation of stars like the Sun about 4.5 billion years ago.

A team from the United States and France used an advanced technique to date the dirt, and were able to calculate the age of the tools, which they place at 1.76 million years.

On its way to probe Jupiter, NASA's Juno spacecraft took the time to capture its home planet Earth and its moon looking like tiny white dots. JunoCam, the name given to the spacecraft's camera, took the image on Aug. 26 when the spacecraft was about 6 million miles (9.66 million kilometers) away from Earth.

The United States could be worse than 40 other countries when it comes to infant mortality.

A team from the United States and France has found newly discovered hand axes from about 1.76 million year ago. The team made the discovery after traveling to an archaeological site located along the northwest shoreline of Kenya's Lake Turkana.

The green anole lizard, also known as Anolis carolinensis, is described as an agile and active creature. It is the first non-bird species of reptile to have its genome sequenced and assembled. The lizard is a native of the Southeastern United States.

By chronologically arranging images produced by Hubble, astronomers have been able to construct a sort of film reel illustrating the birth of stars

Researchers have engineered a virus that attacks cancer cells when injected into patients, a form of treatment that could kill tumors without harming healthy cells.

Scientists have long known that parents heavily influence their offspring, including their levels of and vulnerability to stress.

Babies born in the United States have a higher chance of dying in their first month than babies in much of the developed world, according to a new report on infant mortality rates.
