More grasslands in Tibet could bring climate improvements

2015-08-20
(Press-News.org) In the Arctic, warming increases like a spiral. Global warming means that the periods of growth are becoming longer and vegetation growth is increasing. At the same time, heat transfer to the Arctic from lower latitudes is rising, reducing sea ice there, and this in turn is contributing towards a faster local rise in temperature.

A new research study published in the highly respected research journal PNAS shows that the situation is the reverse on the Tibetan Plateau.

Vegetation on the Tibetan Plateau has also increased as a result of global warming. However, in contrast to the Arctic areas, the longer periods of growth and the increased vegetation activity here appear to mean that global warming is being weakened.

"The reason for this is that increased evapotranspiration from plants is cooling the air," explains Deliang Chen, Professor of Physical Meteorology at the University of Gothenburg.

The climate models also simulate daytime cooling as a result of the increased vegetation, albeit with a smaller magnitude than currently observed.

"Our results suggest that actions to restore native grasslands in degraded areas, roughly one-third of the plateau, will both facilitate a sustainable ecological development in this region and bring local and global climate benefits."

More accurate simulations of the biophysical coupling between the land surface and the atmosphere are needed to help fully understand regional climate change over the Tibetan Plateau.

Small, inexpensive, and incredibly resilient: A new femtosecond laser for industry
2015-08-20
A team at the University of Warsaw, Faculty of Physics has created a laser capable of generating ultrashort pulses of light even under extremely difficult external conditions. This unique combination of precision and resilience is due to the fact that the whole process of generating femtosecond laser pulses takes place within a specially-selected optical fiber. Its appearance seems quite inconspicuous: just a flat, rectangular box, tens of centimeters across and about the same height, with a thin, shiny-tipped "thread" leading out of it, so long that it is rolled up ...

Penn researchers use nanoscopic pores to investigate protein structure

Penn researchers use nanoscopic pores to investigate protein structure
2015-08-20
University of Pennsylvania researchers have made strides toward a new method of gene sequencing a strand of DNA's bases are read as they are threaded through a nanoscopic hole. In a new study, they have shown that this technique can also be applied to proteins as way to learn more about their structure. Existing methods for this kind of analysis are labor intensive, typically entailing the collection of large quantities of the protein. They also often require modifying the protein, limiting these methods' usefulness for understanding the protein's behavior in its natural ...

Aquatic hunger games: Archerfish spit the distance for food

Aquatic hunger games: Archerfish spit the distance for food
2015-08-20
Move over, Katniss Everdeen. For archerfish, the odds are ever in their favor, according to new research from Wake Forest University. The sharp-shooting fish's ability to spit water to hit food targets has been well documented, but a new study published online in the journal Zoology showed for the first time that there is little difference in the amount of force of their water jets based on target distance. And, when given the choice, the fish preferred closer targets. The study was co-authored by Wake Forest researchers Morgan Burnette, a biology graduate student, ...

Warming climate is deepening California drought

Warming climate is deepening California drought
2015-08-20
A new study says that global warming has measurably worsened the ongoing California drought. While scientists largely agree that natural weather variations have caused a lack of rain, an emerging consensus says that rising temperatures may be making things worse by driving moisture from plants and soil into the air. The new study is the first to estimate how much worse: as much as a quarter. The findings suggest that within a few decades, continually increasing temperatures and resulting moisture losses will push California into even more persistent aridity. The study appears ...

Study shows what business leaders can learn from Formula One racing

2015-08-20
COLUMBUS, Ohio - Formula One racing teams may have a lesson to teach business leaders: Innovation can be overrated. That's the conclusion from academic researchers who pored over data from 49 teams over the course of 30 years of Formula One racing. They found that the teams that innovated the most - especially those that made the most radical changes in their cars - weren't usually the most successful on the race course. Moreover, radical innovations were the least successful at exactly the times when many business leaders would be most likely to try them: when there ...

How newts can help osteoarthritis patients

2015-08-20
A research team at York has adapted the astonishing capacity of animals such as newts to regenerate lost tissues and organs caused when they have a limb severed. The research, which is funded by a £190,158 award from the medical research charity Arthritis Research UK, is published in Nature Scientific Reports. The scientists, led by Dr Paul Genever in the Arthritis Research UK Tissue Engineering Centre in the University's Department of Biology, have developed a technique to rejuvenate cells from older people with osteoarthritis to repair worn or damaged cartilage ...

New theory: If we want to detect dark matter we might need a different approach

2015-08-20
Physicists suggest a new way to look for dark matter: They beleive that dark matter particles annihilate into so-called dark radiation when they collide. If true, then we should be able to detect the signals from this radiation. ­The majority of the mass in the Universe remains unknown. Despite knowing very little about this dark matter, its overall abundance is precisely measured. In other words: Physicists know it is out there, but they have not yet detected it. It is definitely worth looking for, argues Ian Shoemaker, former postdoctoral researcher at Centre ...

Stem cells derived from amniotic membrane can benefit retinal diseases when transplanted

2015-08-19
Putnam Valley, NY. (Aug. 19, 2015) - A team of researchers in South Korea has successfully transplanted mesenchymal stromal cells (MSCs) derived from human amniotic membranes of the placenta (AMSCs) into laboratory mice modeled with oxygen-induced retinopathy (a murine model used to mimic eye disease). The treatment aimed at suppressing abnormal angiogenesis (blood vessel growth) which is recognized as the cause of many eye diseases, such as diabetic retinopathy and age-related macular degeneration. The researchers reported that the AMSCs successfully migrated to the retinas ...

NIH scientists and colleagues successfully test MERS vaccine in monkeys and camels

2015-08-19
National Institutes of Health (NIH) scientists and colleagues report that an experimental vaccine given six weeks before exposure to Middle East respiratory syndrome coronavirus (MERS-CoV) fully protects rhesus macaques from disease. The vaccine also generated potentially protective MERS-CoV antibodies in blood drawn from vaccinated camels. A study detailing the synthetic DNA vaccine appears in the Aug. 19 Science Translational Medicine. MERS-CoV, which causes pneumonia deep in the lungs, emerged in 2012 and has sickened more than 1,400 people and killed 500, mostly in ...

Seizures in neonates undergoing cardiac surgery underappreciated and dangerous

2015-08-19
Summary: In 2011, the American Clinical Neurophysiology Society issued a guideline recommending that neonates undergoing cardiac surgery for repair of congenital heart disease be placed on continuous encephalographic (EEG) monitoring after surgery to detect seizures. These recommendations followed reports that seizures are common in this population, may not be detected clinically, and are associated with adverse neurocognitive outcomes. Yet, in a discussion at the 2014 Annual Meeting of The American Association for Thoracic Surgery, 80% to 90% of the audience was not following ...
