A study aided by UA microbiologist Charles Gerba finds that office kitchens and break rooms are frequent hot spots for bacteria.
If you thought the restroom was the epicenter of workplace germs, you don’t want to know about office break rooms and kitchens. (more…)
EAST LANSING, Mich. — An international research team has manufactured a new protein that can combat deadly flu epidemics. (more…)
Like a tourist waiting for just the right lighting to snap a favorite shot during a stay at the Grand Canyon, NASA’s Mars Exploration Rover Opportunity has used a low sun angle for a memorable view of a large Martian crater.
The resulting view catches a shadow of the rover in the foreground and the giant basin in the distance. Opportunity is perched on the western rim of Endeavour Crater looking eastward. The crater spans about 14 miles (22 kilometers) in diameter. Opportunity has been studying the edge of Endeavour Crater since arriving there in August 2011. (more…)
Annika Finne, senior and aspiring conservator, jumped at the chance to investigate the authenticity of a Modigliani painting stored in the archives of the RISD Museum of Art. What followed was a year-long journey of research and discovery and a senior thesis that, Finne hopes, will secure the painting’s place in art history.
PROVIDENCE, R.I. [Brown University] — To the causal observer, the painting is most striking in its simplicity: a two-dimensional image of a woman, her face elongated, head slightly tilted, the background giving away little of her surroundings, the parameters devoid of a signature identifiying the artist.

With LUX ZEPLIN Berkeley Lab researchers seek to increase the sensitivity of LUX, the most sensitive search for dark matter yet, by orders of magnitude
Although it’s invisible, dark matter accounts for at least 80 percent of the matter in the universe. No one knows what it is, but most scientists would bet on weakly interacting massive particles, or WIMPs. (more…)
MENLO PARK, Calif. – 100 years ago, in June 1912, the most powerful volcanic eruption of the 20th century took place in what is now Alaska’s Katmai National Park and Preserve. This massive volcanic event once again comes alive for scholars and enthusiasts in a new centennial volume by two U.S. Geological Survey scientists whose work has made major contributions to volcano science.
“The Novarupta-Katmai Eruption of 1912 – Largest Eruption of the Twentieth Century: Centennial Perspectives,” by Wes Hildreth and Judy Fierstein, is the most comprehensive study of a geographically remote but huge and devastating volcanic event. The eruption’s dynamics mystified researchers for decades. Today, study of Novarupta and Katmai volcanoes sheds light on how future events in Alaska’s volcanic regions could affect air quality and air-transportation safety locally and across the globe.

Scientists believe they’ve pinpointed the last crucial piece of the 80-year-old puzzle of how plants “know” when to flower.
Determining the proper time to flower, important if a plant is to reproduce successfully, involves a sequence of molecular events, a plant’s circadian clock and sunlight.
Understanding how flowering works in the simple plant used in this study – Arabidopsis – should lead to a better understanding of how the same genes work in more complex plants grown as crops such as rice, wheat and barley, according to Takato Imaizumi, a University of Washington assistant professor of biology and corresponding author of a paper in the May 25 issue of the journal Science.

Our ‘gut feelings’ influence our decisions, overriding ‘rational’ thought, when we are faced with financial offers that we deem to be unfair, according to a new study. Even when we are set to benefit, our physical response can make us more likely to reject a financial proposition we consider to be unjust.
Conducted by a team from the University of Exeter, Medical Research Council Cognition and Brain Sciences Unit and University of Cambridge, the research is published in the journal Cognitive, Affective, & Behavioural Neuroscience.
The research adds to growing evidence that our bodies can sometimes govern how we think and feel, rather than the other way round. It also reveals that those people who are more in tune with their bodies are more likely to be led by their ‘gut feelings’. (more…)
