Plants don't mind sharing space with their kin but when they're potted with strangers of the same species they start invigorating their leaves, a study by McMaster University reveals.
The research, which appears in the current issue of the American Journal of Botany, suggests non-kin plants will not only compete underground for soil nutrients, but will attempt to muscle out the competition above ground in the ongoing struggle for light.
CORVALLIS, Ore. – An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan cultures and more – the creation of a near-perfect blue pigment.
AUGUSTA, Ga. – A powerful new breast cancer treatment could result from packaging one of the newer drugs that inhibits cancer's hallmark wild growth with another that blocks a primordial survival technique in which the cancer cell eats part of itself, researchers say.
With 900,000 assisted reproduction treatments annually such as IVF and intrauterine inseminations in Europe the Commission's proposal to screen both partners before each treatment could lead to costs of over EUR 140 million annually. These figures do not include the additional overhead costs such as administration, personnel and documentation that the hospitals would have to carry on top of that. The new interpretation of the EU Directive would have substantial implications on the costs of fertility treatments in Europe.
WASHINGTON, Nov. 16, 2009 — A first-of-its kind inhalable measles vaccine for developing countries, where the disease remains a scourge. A "nanogenerator" that could recharge iPods and other electronic devices with a shake. And for Fido and Fluffy, a long-awaited once-a-month pill for both ticks and fleas.
Kansas State University's Joseph Craine, research assistant professor in the Division of Biology, and KC Olson, associate professor in animal sciences and industry, have teamed up with some other scientists from across the United States to look into the possible effects of climate change on cattle nutrition.
MAYWOOD, Ill. -- Adults who use pet therapy while recovering from total joint-replacement surgery require 50 percent less pain medication than those who do not. These findings were presented at the 18th Annual Conference of the International Society of Anthrozoology and the First Human Animal Interaction Conference (HAI) in Kansas City, Mo.
Drivers who engaged in self-harm were at increased risk of motor vehicle crashes, even after controlling for psychological distress and substance abuse, found a study (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj090459.pdf of 18 871 Australian drivers published in CMAJ (Canadian Medical Association Journal)) (www.cmaj.ca).
When muscle cells need repair, they use odor-detecting tools found in the nose to start the process, researchers have discovered.
The results are published online and scheduled for publication in the November issue of the journal Developmental Cell.
Found on the surfaces of neurons inside the nose, odorant receptors are molecules that bind and respond to substances wafting through the air. Researchers have shown that one particular odorant receptor gene, MOR23, is turned on in muscle cells undergoing repair.
Determining what triggers the death of retinal cells, called photoreceptors, could hold the key to stopping blinding disorders caused by a wide range of eye diseases, Yale School of Medicine researchers report in the November journal Investigative Ophthalmology & Visual Science.
Acute heart attack patients received an average total dose of ionizing radiation equal to 725 chest X-rays from medical tests during their hospital stay, according to research presented at the American Heart Association's Scientific Sessions 2009.
CHICAGO—November 16, 2009—Although global private equity markets have fallen on hard times, reports of their imminent demise are greatly exaggerated. So says Steve Kaplan, a widely recognized authority on entrepreneurial finance and corporate governance and top-rated business school professor at the University of Chicago's Graduate School of Business.
ORLANDO, Fla. - Results of a Mayo Clinic study show the incidence of stroke or mini-stroke related to a coronary angioplasty (http://www.mayoclinic.org/heart-catheterization/types.html) remained steady over a 15-year period. Researchers say this is good news because physicians now are performing the artery-opening procedure on older patients who are sicker and need more complicated treatment.
Researchers from the universities of Bristol and St. Andrews in the UK have found that the color of a person's skin affects how healthy and therefore attractive they appear, and have found that diet may be crucial to achieving the most desirable complexion. The work will be published in the December issue of Springer's International Journal of Primatology.
The electrical measurements on the electrocardiogram can often mislead physicians in diagnosing the heart condition left ventricular hypertrophy, causing other screening tests to be ordered before a definitive conclusion can be made, according to a Henry Ford Hospital study.
The study of 500 patients found a false positive reading between 77 and 82 percent in patients screened by electrocardiogram, and a false negative reading between 6 percent to 7 percentin the same patient population.
