Pollution kills more people than wars, smoking, hunger, disaster, and AIDS. What are some of the unwanted health effects of environmental pollutants that can potentially lead to premature deaths?
An engineered version of the protein GDF15 caused test animals to lose weight. Researchers also observed a link between increased levels of the protein and lowered cholesterol and insulin levels in the blood.
Cetaceans, which include whales and dolphins, have human-like societies. Scientists said that the social and cultural characteristics of these marine animals are due to having evolved big brains.
Artificial intelligence may have greatly improved in the near future. Nanomachines implanted into the body may allow humans to have superhuman strengths. The technology may also allow humans to control things in their environment using only their mind.
Ocean critters produce the highly potent greenhouses gases methane and nitrous oxide. A study finds that clams and worms are behind about 10 percent of methane emissions from the Baltic Sea.
Asteroid 2012 TC4, which came close to Earth earlier this week, will return again in the future. One of these visits may possibly result in a collision with Earth.
Scientists are investigating how a polynya in Antarctica's Weddell Sea formed again after disappearing for 40 years. Is climate change responsible for the formation of this massive hole?
Two groups of scientists have found the missing baryons in hot filaments of gas that link galaxies together. Here's how they found these by taking advantage of the Sunyaev-Zel'dovich effect.
Potassium-rich foods such as bananas and avocados can help protect against heart disease, a study reveals. What are some other examples of food that contain high amounts of potassium?
Japanese scientists have genetically engineered hens to lay eggs that contain interferon beta, a type of protein used as treatment for malignant skin cancer and hepatitis. Here's how they did it.
Experts have warned about the dangers of using the cellphone inside the bathroom. Here's why it is not a good idea to browse through your Facebook News Feed while sitting on the toilet.
Warmer soils release more carbon that can contribute to increase in temperatures. Scientists said that the addition of soil carbon into the atmosphere may accelerate the global warming process.
An alien megastructure could not be the reason behind the mysterious dimming of Tabby's Star. Here's the evidence astronomers found that suggests the star's strange behavior could be explained by dust cloud.
Methane could be behind the warm climate in ancient Mars that allowed liquid water to flow for millennia. What is the primary source of this heat-trapping greenhouse gas on the Red Planet?
Charles Darwin's theory that life on Earth began in warm little ponds may have been plausible. A study suggests that the meteorites that brought ingredients needed for life contributed to the process.
A genital reconstructive surgeon has been providing gender reversal surgery to transgender patients who regretted going through sex change procedures. Miroslav Djordjevic is also concerned over the psychiatric evaluation and counseling patients who consider gender reassignment receive.
Scientists have identified the hominin species responsible for passing genital herpes to our ancient human ancestors. Here's how the virus possibly managed to jump the species barriers.
Researchers used a simple and affordable smell test to determine Alzheimer's risk. Besides the inability to detect the scents of peppermint, orange, fish, rose and leather, here are other early warning signs of dementia.
Methane, a greenhouse gas more potent than carbon dioxide, is produced by cows and other livestock. A study finds that the impact of methane emissions from animals on global warming may have been underestimated.
A marine biologist discovered a blue hole in the Great Barrier Reef while using Google Maps. How do these large underwater sinkholes form and why did it take long for scientists to discover this large marine sinkhole?
PETA revealed that a farm in Cambodia breeds super-muscular pigs. What are the potential problems associated with producing these large and genetically altered animals to produce more meat?
Biologically produced graphite found in 3.95-billion-year-old sedimentary rocks in Labrador, Canada, could be the oldest evidence of life on Earth. What are the implications of the discovery?
The Mars Science City project will build a prototype of a Red Planet colony on Earth. UAE said that it will be the most sophisticated building in the world. Here's how it will simulate Mars environment.
Scientists who embarked on an expedition to study Zealandia returned with a wealth of information about Earth's 8th continent. Here are the discoveries scientists made based on sediment cores retrieved from the seabed.
An elderly woman in Houston, Texas, died of flesh-eating bacteria after she fell into contaminated floodwaters. This is the second case of flesh-eating infection related to Hurricane Harvey. What are the symptoms of necrotizing fasciitis?
The melting sea ice likely brought about by climate change now allows plastic pollution to reach remote areas of the Arctic Ocean. Here's what could possibly happen as a result.
The doomsday predicted by Christian numerologist David Meade did not happen on Sept. 23. He now says that the end of the world will begin in October as the hypothetical Planet X, or Nibiru, approaches Earth.
A parasitic worm was found wriggling in the eyeball of a teenager in Mexico. The nematode was removed but it has already caused serious eye damage. How did it get into the boy's eye?
Travelers were warned that some bottles of 7Up were tampered and contaminated with methamphetamine in Mexico. Should consumers in the United States also worry about meth-laced soft drinks?
The skeleton of a 7-year-old Neanderthal child revealed that kids of the extinct human species grew up similar to modern humans. Researchers also noted "subtle differences" in growth and development.
