Sunglasses on demand (video)
2015-03-17
(Press-News.org) WASHINGTON, March 17, 2015 -- Apart from their style, sunglasses have changed very little in the last few decades. Photochromic lenses that change from clear to tinted in sunlight were a big breakthrough. Now new research from ACS Applied Materials and Interfaces could give that technology a big boost. Researchers at Georgia Tech have developed a polymer coating that changes colors with the push of a button. John Reynolds, Ph.D. and his team explain these "sunglasses on demand" in the latest episode of ACS Headline Science available here: https://youtu.be/RlfOcSUpyAA.

Research uncovers flawed IQ scoring system

2015-03-17
Queen's University professor Allyson Harrison has uncovered anomalies and issues with the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), one of the most widely used intelligence tests in the world. IQ scores are used to predict educational success, to help identify intellectual disabilities or intellectual giftedness and to establish whether a person has a specific learning disability. For her research, Dr. Harrison and her colleagues examined the differences between Canadian and American WAIS-IV scores from 861 postsecondary students from across Ontario. ...

17 million-year-old whale fossil provides first exact date for East Africa's puzzling uplift

17 million-year-old whale fossil provides first exact date for East Africas puzzling uplift
2015-03-17
Uplift associated with the Great Rift Valley of East Africa and the environmental changes it produced have puzzled scientists for decades because the timing and starting elevation have been poorly constrained. Now paleontologists have tapped a fossil from the most precisely dated beaked whale in the world -- and the only stranded whale ever found so far inland on the African continent -- to pinpoint for the first time a date when East Africa's mysterious elevation began. The 17 million-year-old fossil is from the beaked Ziphiidae whale family. It was discovered 740 ...

Routine clot removal after heart attack not beneficial, may increase risk

2015-03-17
SAN DIEGO (March 16, 2015) -- A technique used to clear blood clots from arteries to the heart in about 20 percent of patients undergoing angioplasty appears to increase the risk of stroke without providing the intended benefit, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session. The new study, which included more than 10,000 patients undergoing angioplasty in response to a severe heart attack, randomly assigned half of the patients to receive angioplasty alone and half to receive angioplasty with manual thrombectomy, ...

Patients 80 years and older would benefit from aggressive treatment

2015-03-17
SAN DIEGO (March 16, 2015) -- Patients over age 80 with acute coronary syndromes would likely benefit from more invasive tests and therapies that may otherwise be denied them due to their age, according to research presented at the American College of Cardiology's 64th Annual Scientific Session in San Diego. The study focused on treatment approaches for older patients with non ST-elevation myocardial infarction (NSTEMI, a type of heart attack that is milder in the acute phase but has a poor prognosis after six months or more) or the closely-related condition unstable ...

Trial of bivalirudin during angioplasty reports mixed results

2015-03-17
Patients with acute coronary syndrome undergoing angioplasty who received the anticoagulant drug bivalirudin did not show significant improvements in either of two co-primary endpoints--a composite of rate of death, heart attack or stroke at 30 days, or a composite of those events plus major bleeding--as compared to patients receiving standard anticoagulation therapy, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session. However, bivalirudin was associated with significantly lower rates of bleeding complications and death, ...

Arm is safer access point than groin for catheter-based heart procedures

2015-03-17
SAN DIEGO (March 16, 2015) -- Patients with acute coronary syndrome undergoing coronary angiogram, a procedure used to assess blockages in the heart's arteries, had a significantly lower risk of major bleeding and death if their interventional cardiologist accessed the heart through an artery in the arm rather than the groin, according to research presented at the American College of Cardiology's 64th Annual Scientific Session. Study authors said the results should prompt a re-evaluation of clinical guidelines and that the arm, currently used in a minority of cases in the ...

UNC-Chapel Hill researchers collaborate to develop revolutionary 3-D printing technology

2015-03-17
A 3D printing technology developed by Silicon Valley startup, Carbon3D Inc., enables objects to rise from a liquid media continuously rather than being built layer by layer as they have been for the past 25 years, representing a fundamentally new approach to 3D printing. The technology, to appear as the cover article in the March 20 print issue of Science, allows ready-to-use products to be made 25 to 100 times faster than other methods and creates previously unachievable geometries that open opportunities for innovation not only in health care and medicine, but also in ...

Study reveals previously unknown site of anesthetic action

2015-03-17
Anesthetics have been used in surgical procedures for more than 150 years, but the mechanisms by which inhaled anesthesia actually work are poorly understood. Now, researchers at Johns Hopkins Medicine have discovered that anesthetics bind to and interfere with certain proteins in excitatory neurons, which are necessary for these neurons to transmit signals involved in anesthesia and the perception of pain. "Our discovery may be an important component of the mechanism of anesthesia and -- because this particular protein is also involved in neuronal development -- could ...

Joint fluid harbors bacterial clumps after replacement despite pre-surgery antibiotics

2015-03-17
PHILADELPHIA, PA - March 17, 2015- Researchers at Thomas Jefferson University and the National Institutes of Health are building on their research which seeks to understand why joint infections persist despite standards of care designed to stop them. More Americans than ever will receive joint replacements, and with an infection rate of approximately 1 percent, the potential exists for tens of thousands to experience post-operative infection and complications each year. "In this study, we decided to find out if pre-operative, prophylactic antibiotic concentrations in ...

Emerging diseases likely to be more harmful in similar species

2015-03-17
When viruses such as influenza and Ebola jump from one species to another, their ability to cause harm can change dramatically, but research from the University of Cambridge shows that it may be possible to predict the virus's virulence by looking at how deadly it is in closely-related species. A number of emerging infectious diseases - including some of the most deadly outbreaks such as Ebola, SARS and HIV - are the result of humans becoming infected with a pathogen that normally infects another species. The amount of harm caused by a pathogen when it jumps into a new ...
