A group including a consultant, a sustainability advocate and an environmental scientist argued today at the Geological Society of America meeting in Denver that while the use of hydraulic fracturing and horizontal drilling for "tight oil" is an important contributor to U.S. energy supply, it is not going to result in long-term sustainable production or allow the U.S. to become a net oil exporter.

Experiments on individual photons conducted by physicists from the Faculty of Physics at the University of Warsaw (FUW) and the Faculty of Applied Physics and Mathematics at the Gdansk University of Technology (PG), have revealed yet another bizarre feature of the quantum world.

When a quantum object is transmitted, its quantum property, whether it behaves as a wave or as a particle, appears to depend on other properties that at first glance have nothing to do with the transmission, they argue.

You might think that health care professionals would become jaded to the plights of people over time - especially in an intensive care ward for burn patients.

Not so, according to a paper which catalogs the emotional and psychological anguish, known as "moral distress," experienced by nurses in an intensive care unit for burn patients.
A burn ICU can be an intense work environment. Many patients suffer significant pain and disfigurement. They may be in the ICU for weeks, and require numerous procedures and surgeries.

Even brief usage of anabolic steroids may have long lasting, perhaps even permanent performance-enhancing effects, according to a new study.

It was previously believed that re-acquisition of muscle mass after periods of inactivity was due to motor learning. The new data from an investigation of  the effects of steroids on muscle re-acquisition in mice suggests that there is a cellular 'memory mechanism' within muscle of brief steroid users.

The team investigated the effects of steroids on muscle re-acquisition in mice and discovered greater muscle mass and more myonuclei, which are essential components for muscle fiber function, were apparent after returning to exercise.

An analysis of the nation's largest 10-kilometer road running races show that women are in the majority. Researchers analyzed data from more than 400,000 runners who participated in 10 of the largest 10K (6.2 mile) races in the U.S. from as early as 2002 through 2011.  

Might we one day predict summer heat waves?

A distinctive atmospheric wave pattern high above the Northern Hemisphere can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance, according to research led by scientists at the National Center for Atmospheric Research (NCAR) that could potentially forecast heat waves 15-20 days out. Heat waves are among the most deadly weather phenomena on Earth. A heat wave in Europe in 2003 killed more than 50,000 people. 

Pediatric musculoskeletal Staphylococcus aureus bacterial infections have been evolving over the past decade, with more children diagnosed with the more virulent, methicillin-resistant Staphylococcus aureus (MRSA) today than 10 years ago. The result is longer hospitals stays, more surgeries and other related complications.

The researchers studied pediatric patients with culture-positive Staphylococcus aureus, including MRSA and the less toxic methicillin-sensitive Staphylococcus aureus (MSSA), between January 2001 and June 2010, at a major urban children's hospital.

Living with Type 1 and Type 2 diabetes means constant awareness of blood glucose (sugar) levels to ensure they remain stable.

People do this at home using electronic devices that read sugar levels in a tiny drop of blood but a team of German researchers has devised a new, non-invasive method; infrared laser light applied on top of the skin measures sugar levels in the fluid in and under skin cells.  

"This opens the fantastic possibility that diabetes patients might be able to measure their glucose level without pricking and without test strips," said lead researcher, Werner Mäntele, Ph.D. of Frankfurt's Institut für Biophysik, Johann Wolfgang Goethe-Universität.

A young woman, a student it seems from the looks of it, shuffles in bursts behind me, in small steps one foot just in front of the other, staring down, then she wiggles her head at the sky, then she shuffles on, stops, wiggles her head. The light turns green and I walk, just walk away as if I must, feeling guilty, fleeing the scene. I steal one more look, also because she is attractive. An easy mark for the fulfillment of desires – who would ever know if I took her in the dusk? I feel for her, feel pain, but then I envy her, too. She has an aim, perhaps. She has her way of dealing with her pains, perhaps she deals with them in this way, and I am here to suffer, not able to deal with mine nearly as efficient. Broken robots, but nature’s, never not “broken”.
