Lions and leopards are endangered species. Robins and raccoons clearly are not. The distinction seems simple until one ponders a question such as: How many lions would there have to be and how many of their former haunts would they have to inhabit before we'd agree they are no longer endangered?
To put a fine point on it, what is an endangered species? The quick answer: An endangered species is at risk of extinction. Fine, except questions about risk always come in shades and degrees, more risk and less risk.
Toronto - (January 17, 2020) In an unprecedented pan-cancer analysis of whole genomes, researchers at the Ontario Institute for Cancer Research (OICR) have discovered new regions of non-coding DNA that, when altered, may lead to cancer growth and progression.
The study, published today in Molecular Cell, reveals novel mechanisms of disease progression that could lead to new avenues of research and ultimately to better diagnostic tests and precision therapies.
HAMILTON, ON (Jan. 17, 2019) - Scurvy, the debilitating condition remembered as a disease of pirates, is still found in Canada.
The disease, which is caused by a vitamin C deficiency, can result in bruising, weakness, anemia, gum disease, hemorrhage, tooth loss, and even death if undiagnosed and untreated.
DURHAM, N.C. -- Few singers reach their sunset years with the same voice they had in younger days. Singing sparrows are no different. Duke University-led research reveals that elderly swamp sparrows don't sound quite like they used to -- nor do they strike the same fear in other males who may be listening in.
Humans are remarkably good at guessing a person's age just by hearing their voice. But this is the first time the phenomenon has been demonstrated in wild animals, said Duke biology professor and study co-author Steve Nowicki.
HANOVER, N.H. - January 17, 2020 - Researchers from Dartmouth and the Massachusetts Institute of Technology (MIT) have developed an original approach to flight scheduling that, if implemented, could result in a significant increase in profits for airlines and more flights that align with passengers' preferences.
WASHINGTON, January 17, 2020 -- Specially designed vacuum suction units allow humans to climb walls. Scientists have developed a suction unit that can be used on rough surfaces, no matter how textured, and that has applications in the development of climbing robots and robotic arms with grasping capabilities.
Traditional methods of vacuum suction and previous vacuum suction devices cannot maintain suction on rough surfaces due to vacuum leakage, which leads to suction failure.
BIRMINGHAM, Ala. - The lungs and placentas of fetuses in the womb -- as young as 11 weeks after conception -- already show a bacterial microbiome signature, which suggests that bacteria may colonize the lungs well before birth. This first-time finding deepens the mystery of how the microbes or microbial products reach those organs before birth and what role they play in normal lung and immune system development.
When NASA's Aqua satellite passed over the Southern Pacific Ocean it gathered water vapor data that provided information about the intensity of Tropical Cyclone Tino.
Tropical Cyclone Tino formed near Fiji in the Southern Pacific Ocean and NASA's Aqua satellite provided meteorologists with a look at the water vapor content of the storm showing potential for heavy rain.
DARIEN, IL - Older adults with undiagnosed obstructive sleep apnea seek more health care, according to a study published in the January issue of the Journal of Clinical Sleep Medicine. The study examined the impact of untreated sleep apnea on health care utilization and costs among Medicare beneficiaries.
On average, an estimated three out of every 1,000 newborns will suffer a brachial plexus injury during birth, damaging the bundle of nerves that connect the brain and spinal cord to the shoulders, arms and hands. In the most traumatic cases, even with surgery and physical therapy as an infant, there is no treatment that can guarantee a full recovery.
