The study is the first to put antibiotic biosynthesis and resistance into an evolutionary context. The findings will help to guide the future discovery of new antibiotics and antibiotic alternatives which are medicines that are vitally needed given the current global threat of antimicrobial resistance.
Impact of largescale tree death on carbon storage
- ScienceDaily
- 19/8/12 23:23
Largescale 'disturbances', including fires, harvesting, windstorms and insect outbreaks, which kill large patches of forest, are responsible for more than a tenth of tree death worldwide, according to new research.
Smoldering spots in the brain may signal severe MS
- ScienceDaily
- 19/8/12 23:23
Aided by a high-powered brain scanner and a 3D printer, researchers peered inside the brains of hundreds of multiple sclerosis patients and found that dark rimmed spots representing ongoing, 'smoldering' inflammation, called chronic active lesions, may be a hallmark of more aggressive and disabling forms of the disease.
Icebergs delay Southern Hemisphere future warming, study shows
- ScienceDaily
- 19/8/12 23:23
Future warming can accelerate the disintegration of the West Antarctic ice sheet. A large fraction of the ice will enter the Southern Ocean in form of icebergs, which melt and provide a cooling and freshening effect to the warmer and denser ocean water. This process will increase the formation of sea-ice and shift winds and ocean currents. The overall effect is a slowdown in the magnitude of...
Asian longhorned beetle larvae eat plant tissues that their parents cannot
- ScienceDaily
- 19/8/12 23:23
Despite the buzz in recent years about other invasive insects that pose an even larger threat to agriculture and trees -- such as the spotted lanternfly, the stink bug and the emerald ash borer -- Penn State researchers have continued to study another damaging pest, the Asian longhorned beetle.
Potential for Rift Valley fever virus transmission in Colorado livestock

Excess body fat, particularly around the waist, is a major risk factor for premature death among Hispanics
- ScienceDaily
- 19/8/12 23:23
Both general and abdominal obesity were strongly associated with mortality among Mexican adults. Each 5 kg/m2 increase in BMI above 25 kg/m2 was associated with a 30 percent increase in mortality. These findings refute previous research showing that being overweight was not strongly associated with mortality in Hispanic populations.

Maryland panel on lynching begins study of killings
A Maryland commission that will research at least 40 lynchings committed in the state between 1854 and 1933 and make recommendations about reconciliation held its first meeting Monday. The Maryland Lynching Truth and Reconciliation Commission meeting was largely organizational, with members choosing an acting chairman and discussing future meetings. "We have never really looked at it, looked at...

Gut-brain connection helps explain how overeating leads to obesity
- ScienceDaily
- 19/8/12 22:05
A multi-institutional team reveals a previously unknown gut-brain connection that helps explain how those extra servings lead to weight gain.
First cells may have emerged because building blocks of proteins stabilized membranes
- ScienceDaily
- 19/8/12 21:55
Scientists have discovered that the building blocks of proteins can stabilize cell membranes. This finding may explain how the first cells emerged from the primordial soup billions of years ago: The protein building blocks could have stabilized cell membranes against salt and ions that were present in ancient oceans. In addition, membranes may have been a site for these precursor molecules to...
Osteoporosis drugs linked to reduced risk of premature death
- ScienceDaily
- 19/8/12 21:54
A large cohort study has revealed a common osteoporosis drug significantly decreases premature mortality risk, likely related to a reduction in bone loss.

Natural-gas leaks are important source of greenhouse gas emissions in Los Angeles
In discussions of anthropogenic climate change, carbon dioxide generally gets the spotlight, but it is not the only greenhouse gas spewed into the atmosphere by human activity, nor is it the most potent.
Ancient pigs endured a complete genomic turnover after they arrived in Europe
- ScienceDaily
- 19/8/12 21:22
New research has resolved a pig paradox. Archaeological evidence has shown that pigs were domesticated in the Near East and as such, modern pigs should resemble Near Eastern wild boar. They do not. Instead, the genetic signatures of modern European domestic pigs resemble European wild boar.
Poor fit between job demands, reasoning abilities associated with health conditions
- ScienceDaily
- 19/8/12 21:21
Older workers whose reasoning abilities no longer allow them to meet the demands of their jobs may be more likely to develop chronic health conditions and retire early, which may not be ideal for the employee or employer, according to new research.
NASA-NOAA satellite views massive Tropical Storm Krosa
Tropical Storm Krosa is a large tropical cyclone. When NASA-NOAA's Suomi NPP satellite passed over the Northwestern Pacific Ocean, it captured a visible image of the massive storm.

Detention basins could catch more than stormwater
Everywhere you go there are stormwater detention basins built near large construction projects intended to control the flow of rainwater and runoff. Now, those basins might help in controlling nitrogen runoff into rivers and lakes, according to Lauren E. McPhillips, assistant professor of civil and environmental engineering at Penn State.
Largest-ever study of coral communities unlocks global solution to save reefs
The largest study ever conducted of its kind has identified where and how to save coral reef communities in the Indo-Pacific, according to an international group of scientists from WCS (Wildlife Conservation Society) and other conservation NGOs, government agencies, and universities. The study outlines three viable strategies that can be quickly enacted to help save coral reefs that are threatened...

Life on Earth arose about 4 billion years ago when the first cells formed within a primordial soup of complex, carbon-rich chemical compounds.
Mapping the effects of drought on vulnerable populations
The greater frequency of droughts, combined with underlying economic, social and environmental risks, means that dry spells have an increasingly destructive impact on vulnerable populations, and particularly on children in the developing world. In a new study by researchers from IIASA and the U.S., the team set out to map at-risk populations at the global scale.
Northern tropical dry trend may just be normal variation
