Athletes in next year's Summer Olympics will be swimming and boating in waters so contaminated with human feces that they risk becoming violently ill and unable to compete in the games, an investigation has found.
The New Horizons mission reached the outer fringes of our solar system in recent weeks, snapping vibrant pictures of Pluto, providing new scientific information from millions of miles away and exciting the curious back here on Earth. But the Dawn mission has continued to seek out new worlds and solve galactic mysteries– just without as much fanfare.
Laboratory Equipment’s scientist of the week is Paul Spagnuolo from the University of Waterloo. He and a team found that molecules derived from avocados could be effective in treating a form of cancer.
An exotic material called gallium nitride (GaN) is poised to become the next semiconductor for power electronics, enabling much higher efficiency than silicon. An MIT spinout has announced a line of GaN transistors and power electronic circuits that promise to cut energy usage in data centers, electric cars and consumer devices by 10 to 20 percent worldwide by 2025.
An analysis of data on stomach acidity and diet in birds and mammals suggests that high levels of stomach acidity developed not to help animals break down food, but to defend animals against food poisoning. The work raises interesting questions about how modern life may be affecting both our stomach acidity and the microbial communities that live in our guts.
Controversy over Planned Parenthood's supplying fetal tissue for research has focused attention on a little-discussed aspect of science. Here are some basic facts about fetal tissue use in research and its history.
A potentially influential new ruling from the 7th U.S. Circuit Court of Appeals considered the question of how much police should rely on their K-9 partners to justify searches when a dog's own competence is itself suspect.
A group of researchers has reached deep into the human gut, plucked out a couple enzymes produced by bacteria residing there and determined their biological activities and molecular structures— details that should shed new light on how we digest many of the foods we eat.
Research has shown, for the first time, that— despite not having a nervous system— plants use signals normally associated with animals when they encounter stress. Scientists have reported on how plants respond to their environment with a similar combination of chemical and electrical responses to animals, but through machinery that is specific to plants.
With the results of a new study, neuroscientists have a firmer grasp on the way the brain formulates commands for the hand to grip an object. The advance could lead to improvements in future brain-computer interfaces that provide people with severe paralysis a means to control robotic arms and hands using their thoughts.
The chemical element lithium has been found for the first time in material ejected by a nova. Observations of Nova Centauri 2013 help to explain the mystery of why many young stars seem to have more of this chemical element than expected.
Diseases like Alzheimer’s are caused when proteins aggregate and clump together. In a world first, scientists have successfully distinguished between the disease-causing aggregation forms of proteins. The finding can help change pharmaceutical treatment of neurodegenerative diseases.
Since the 17th century, it’s been a mystery without solution: two pendulum clocks on the same wall will eventually synchronize, after a matter of days or even hours. Even the inventor of the clock could not explain it.
A Minnesota dentist went on an African safari with a bow and arrow. He illegally killed a well-known lion in a national park in Zimbabwe– and then allegedly tried to destroy the GPS collar the big protected cat was wearing.
Reduced street lighting in England and Wales is not associated with road traffic collisions or crime, according to research. The study suggests that local authorities can safely reduce street lighting at night, saving energy costs and reducing carbon emissions.
In astronomical terms, a blue moon is the name for the second full moon that occurs in a single month. We already had a full moon on July 2, so when a full moon rises again on Friday, July 31, it will indeed be a blue moon. It just won't appear blue in color. But that’s not to say there has never been a real blue-colored moon.
