Good Eye: Video Testing May Help Find More 'Disciplined' Baseball Players

ACSH - Jan 12 2018 - 07:01

Since its inception roughly 130 years ago, professional baseball has changed in countless ways. But perhaps one aspect of the game that's remained virtually the same is the relative unreliability of scouting, the process of identifying those top few prospects, from hundreds of thousands of global candidates each year, who will develop into bonafide stars.

Many forms of technology – computers, video, slow-motion cameras, to name a few – have helped narrow this field and minimize the frustrating and costly occurrence of that supposed "cant-miss" player becoming a "bust."

Is There a Wave of Republicans Retiring from Congress? Statistics Say No

ACSH - Jan 12 2018 - 05:01

Midterm elections are often tough for the party in power. 1994 and 2010 were disastrous years for Democrats, and some political pundits think the Republicans may be facing a similar punishment in 2018.

First method to detect illicit drone filming developed

Eurekalert - Jan 12 2018 - 00:01
'The beauty of this research is that someone using only a laptop and an object that flickers can detect if someone is using a drone to spy on them,' says Ben Nassi, a Ph.D. student in the BGU Department of Software and Information Systems Engineering and a researcher at the BGU Cyber Security Research Center (CSRC). 'While it has been possible to detect a drone, now someone can also tell if it is recording a video of your location or something else.'

Can early symptoms predict bipolar disorder? Evidence shows differing patterns of risk factors

Eurekalert - Jan 12 2018 - 00:01
Two patterns of antecedent or 'prodromal' psychiatric symptoms may help to identify young persons at increased risk of developing bipolar disorder (BD), according to a new analysis in the Harvard Review of Psychiatry. The journal is published by Wolters Kluwer.

Don't let skiing and snowboarding injuries take you downhill

Eurekalert - Jan 12 2018 - 00:01
Skiing and snowboarding are fun winter sports. As the popularity of these winter sports continue to rise, according to a review article published in the Jan. 1, 2018, issue of the Journal of the American Academy of Orthopaedic Surgeons, the number of skier and snowboarder injuries also continues to rise.

Penn-led team uncovers the physiology behind the hour-long mating call of midshipman fish

Eurekalert - Jan 12 2018 - 00:01
A new study led by University of Pennsylvania researchers provides an explanation for how Pacific midshipman fish can generate a mating call that emits continuously from their bodies for a full hour, entailing 360,000 muscle contractions.

Stingray soft robot could lead to bio-inspired robotics

Eurekalert - Jan 12 2018 - 00:01
UCLA bioengineering professor Ali Khademhosseini has led the development of a tissue-based soft robot that mimics the biomechanics of a stingray. The new technology could lead to advances in bio-inspired robotics, regenerative medicine and medical diagnostics.

Research suggests Trump's 'Muslim ban' produced rare shift in public opinion

Eurekalert - Jan 12 2018 - 00:01
Visible resistance to Executive Order 13769, commonly referred to the 'Muslim ban,' may have produced a rare shift in public opinion caused by 'an influx of information portraying the ban as being at odds with egalitarian principles of American identity and religious liberty,' said researchers Loren Collingwood of the University of California, Riverside; Nazita Lajevardi of Michigan State University; and Kassra A. R. Oskooii of the University of Delaware.

Nanostructure boosts stability of organic thin-film transistors

Eurekalert - Jan 12 2018 - 00:01
A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric and protects the organic semiconductor - which had previously been vulnerable to damage from the ambient environment.

Past exposures shape immune response in pediatric acute respiratory infections

Eurekalert - Jan 12 2018 - 00:01
By analyzing immune cells of children who came to the emergency department with flu symptoms, researchers found that the suite of genes these early-response cells expressed was shaped by factors such as age and previous exposures to viruses. Better understanding how early infections influence long-term immune response has implications for the diagnosis and treatment of young patients who suffer from acute respiratory tract infections.

Research shows importance of second pediatric blood-pressure screening

Eurekalert - Jan 12 2018 - 00:01
Nearly one-quarter of children and teens who had their blood pressure screened at a primary care appointment showed a reading in the hypertensive range, but less than half of those readings could be confirmed after the blood pressure was repeated, according to a new Kaiser Permanente study released today in The Journal of Clinical Hypertension. The research shows the importance of taking a second blood pressure reading for those ages 3 to 17 years when the first reading is elevated.

Cancer's gene-determined 'immune landscape' dictates progression of prostate tumors

Eurekalert - Jan 12 2018 - 00:01
The field of immunotherapy -- the harnessing of patients' own immune systems to fend off cancer -- is revolutionizing cancer treatment today. However, clinical trials often show marked improvements in only small subsets of patients, suggesting that as-yet unidentified variations among tumors result in distinct paths of disease progression and response to therapy.

The combination of two proteins exerts a regenerating effect in Parkinson's disease

Eurekalert - Jan 12 2018 - 00:01
Current therapies for Parkinson's disease are mainly of a replacement type and pose problems in the long term, so the challenge is to establish an early diagnosis and develop neuroprotective and neurorestorative therapies that will allow the symptoms of the disease to be slowed down or even reversed. As part of her PhD thesis, Catalina Requejo, documented the regenerative, neuroprotective effect of two neurotrophic factors when they are applied in a combined way.
