Sewage Treatment Effluent May Contribute to Antibiotic Resistance

Water discharged into lakes and rivers from municipal sewage treatment plants may contain significant concentrations of the genes that make bacteria antibiotic-resistant. That’s the conclusion of a new study on a sewage treatment plant on Lake Superior in the Duluth, Minn., harbor that appears in ACS’ journal Environmental Science & Technology. Timothy M. LaPara and […]

Sanitation Proposal for Third World Countries Gets Backing by Gates Foundation

DURHAM, N.C. — For less than $100 and a day’s work, a single family in an undeveloped country can construct a solid waste disposal system that not only processes the waste, but requires no electricity or additional energy while destroying harmful pathogens. So argues a Duke University environmental engineer who envisions a simple system that […]

Fruit Fly Intestine May Hold Fountain of Youth

One of the few reliable ways to extend an organism’s lifespan, be it a fruit fly or a mouse, is to restrict calorie intake. Now, a new study in fruit flies is helping to explain why such minimal diets are linked to longevity and offering clues to the effects of aging on stem cell behavior. […]

USDA Discovers Mysterious Plant in Gypsy Graveyard

A U.S. Department of Agriculture (USDA) scientist has confirmed the identity of a strange grass-like sedge discovered in a Mississippi graveyard, and believes the appearance of the potentially invasive plant is linked to the final resting places of several members of a royal Gypsy family. Agricultural Research Service (ARS) botanist Charles Bryson was asked by […]

The Mystery of Dark Matter Deepens

Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter holding them together, our galaxy’s speedy stars would fly off in all directions. The nature of dark matter is a mystery — a mystery that […]

Crash-Safe Batteries Challenging for Electric Cars

If an electric car wants to be environmentally friendly it must weigh as little as possible, because when the light turns green every additional pound/kilogram must be accelerated with considerable energy expenditure. And the lighter the electric vehicle, the longer it can be on the road without having to be plugged back into a power […]

ALMA Opens Its Eyes and Reveals First Image

The most powerful millimeter/submillimeter-wavelength telescope in the world opens for business and reveals its first image At present, around a third of ALMA’s eventual 66 radio antennas, with separations up to only 125 metres rather than the maximum 16 kilometres, make up the growing array on the Chajnantor plateau in northern Chile, at an elevation […]

Scientists Use Brain Imaging to See Into Our Minds Eye

Imagine tapping into the mind of a coma patient, or watching one’s own dream on YouTube. With a cutting-edge blend of brain imaging and computer simulation, scientists at the University of California, Berkeley, are bringing these futuristic scenarios within reach. Using functional Magnetic Resonance Imaging (fMRI) and computational models, UC Berkeley researchers have succeeded in […]

Could the Higgs Boson Explain the Size of the Universe?

The universe wouldn’t be the same without the Higgs boson — this legendary particle plays a role in cosmology and reveals the possible existence of another closely related particle The Universe wouldn’t be the same without the Higgs boson. This legendary particle plays a role in cosmology and reveals the possible existence of another closely […]

New Discovery May Increase Smartphone Battery Life

A new “subconscious mode” for smartphones and other WiFi-enabled mobile devices could extend battery life by as much as 54 percent for users on the busiest networks. University of Michigan computer science and engineering professor Kang Shin and doctoral student Xinyu Zhang will present their new power management approach Sept. 21 at the ACM International […]
