EARTH: Closing the gap in the tetrapod fossil record


2015-09-10
(Press-News.org) Alexandria, VA - In a study covered by EARTH Magazine, geoscientists identified fossils that are helping close the 15-million-year period in the fossil record known as Romer's Gap - the time from when fish showed early evidence of arms and legs until we definitively see four-legged land animals.

Scientists have been wondering for decades whether Romer's Gap exists because tetrapod fossils from that time were not preserved, or because their fossils simply have not been discovered yet. These new fossils are starting to close the gap and change the way scientists interpret the way Earth's history. Read more in the September issue of EARTH Magazine: http://bit.ly/1UzxBzJ.

For more of the science behind the headlines, read the September issue, which includes stories on the geology behind one of the world's largest silic igneous provinces and one of the top 10 beaches on the planet: Australia's Whitsunday Islands. Also included are research headlines like how geoscientists are using seismometers to listen for falling rocks in Yosemite and how the fate of atolls may not necessarily be tied to sea-level rise, and much, much more.

Frozen embryos as successful as fresh embryos in IVF

2015-09-10
IVF cycles using embryos that have been frozen and thawed are just as successful as fresh embryos according to a new UNSW report. The Assisted Reproductive Technology in Australia and New Zealand 2013 report, by UNSW's National Perinatal Epidemiology and Statistics Unit (NPESU), shows in the five years to 2013, fresh embryo IVF cycles that resulted in a baby remained stable at around 23%. However, there has been a more than 25% increase in the birth rate for frozen embryo transfers in the last five years, rising from 18% to 23%. The report also found a growing number ...

Surgery improves quality of life for patients with chronic sinus infection, sleep dysfunction

2015-09-10
Patients with chronic rhinosinusitis (sinus infection) and obstructive sleep apnea report a poor quality of life, which is substantially improved following endoscopic sinus surgery, according to a study published online by JAMA Otolaryngology-Head & Neck Surgery. A growing body of literature has highlighted the important links between quality of life (QOL), sleep, and chronic rhinosinusitis (CRS), such that disease severity has been correlated with worse QOL and patients with worse QOL have poor sleep. It is possible that CRS propagates sleep dysfunction through many ...

Problematic relationship: Small brain models distort contact intensity between neurons

Problematic relationship: Small brain models distort contact intensity between neurons
2015-09-10
This news release is available in German. The goal of brain simulations using supercomputers is to understand the processes in our brain. This is a mammoth task: the activity of an estimated 100 billion nerve cells - also known as neurons - must be represented . It is also a task that has historically been impossible because even the most powerful computers in the world can only simulate one percent of the nerve cells due to memory constraints. For this reason, scientists have turned to downscaled models. However, this downscaling is problematic, as shown by a recent ...

NASA looks at Japan's torrential rains and winds from twin tropical cyclones

NASA looks at Japans torrential rains and winds from twin tropical cyclones
2015-09-10
Japan has experienced large rainfall that caused flooding and large evacuations as a result of two weather systems. NASA's GPM Core satellite measured rainfall as NASA's RapidScat saw Etau and Typhoon Kilo on either side of Japan. Over the past week Japan has experienced extreme rainfall that resulted in flooding, landslides and many injuries. A nearly stationary front that was already moving over Japan caused much of the rain but Tropical Storm Etau also interacted with the front and magnified the scale of the deluge. Heavy rainfall led to the evacuation of over one ...

Major complication of Parkinson's therapy explained

Major complication of Parkinsons therapy explained
2015-09-10
NEW YORK, NY (September 10, 2015)--Researchers have discovered why long-term use of L-DOPA (levodopa), the most effective treatment for Parkinson's disease, commonly leads to a movement problem called dyskinesia, a side effect that can be as debilitating as Parkinson's disease itself. Using a new method for manipulating neurons in a mouse model of Parkinson's, a Columbia University Medical Center (CUMC) research team found that dyskinesia arises when striatonigral neurons become less responsive to GABA, an inhibitory neurotransmitter. This suggests that it may be possible ...

Consensus statement regarding access and inclusion of geoscientists with disabilities

2015-09-10
Alexandria, VA - The American Geosciences Institute's (AGI) is pleased to announce the release of a community consensus statement on access and inclusion of geoscientists with disabilities. This statement was inspired by the 2014 AGI Leadership Forum, which brought together the Executive Directors and Presidents of AGI's Member Societies to discuss the issue of access and inclusion of persons with disabilities in the geosciences. The meeting was facilitated by the Executive Director of the International Association for Geoscience Diversity (IAGD) Christopher Atchison, ...

NASA's RapidScat looks at Tropical Storm Henri's winds

NASAs RapidScat looks at Tropical Storm Henris winds
2015-09-10
NASA's RapidScat instrument analyzed the sustained surface winds of Tropical Storm Henri on Sept. 8 as the storm was intensifying. When the International Space Station flew over Tropical Depression 8 in the Eastern Atlantic Ocean on September 8 at 1p.m. EDT, NASA's RapidScat instrument aboard captured data on the storm's surface winds. RapidScat showed that there were tropical-storm-force winds north and east of the center near 27 meters per second (60.4 mph/97.2 kph). However, sustained winds on the west and southwestern quadrants were near 12 meters per second (26.8 ...

A snapshot of Americans' knowledge about science

2015-09-10
September 10, 2015 (Washington) - There are substantial differences among Americans when it comes to knowledge and understanding of science topics, especially by educational levels as well as by gender, age, race and ethnicity, according to a new Pew Research Center report. The representative survey of more than 3,200 U.S. adults finds that, on the 12 multiple-choice questions asked, Americans gave more correct than incorrect answers. The median was eight correct answers out of 12 (mean 7.9). Some 27% answered eight or nine questions correctly, while another 26% answered ...

Changing patient's position helps effectiveness of colonoscopy -- especially on one side

2015-09-10
DOWNERS GROVE, Ill.-- September 10, 2015--Having patients lie on their left side while the right side of their colon is being examined can result in more polyps being found, thus increasing the effectiveness of colonoscopy for colorectal cancer (CRC) screening, according to a study in the September issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE). CRC is one of the most common cancers in the US and other western countries. Studies have shown that deaths from CRC are reduced ...

Cocoa flavanols lower blood pressure and increase blood vessel function in healthy people

Cocoa flavanols lower blood pressure and increase blood vessel function in healthy people
2015-09-10
Two recently published studies in the journals Age and the British Journal of Nutrition (BJN) demonstrate that consuming cocoa flavanols improves cardiovascular function and lessens the burden on the heart that comes with the ageing and stiffening of arteries. The studies also provide novel data to indicate that intake of cocoa flavanols reduces the risk of developing cardiovascular disease (CVD). As we age, our blood vessels become less flexible and less able to expand to let blood flow and circulate normally, and the risk of hypertension also increases. Arterial stiffness ...
