Astronomy & Space news

	Astronomers image the exploding fireball stage of a nova Astronomers at Georgia State University's Center for High Angular Resolution Astronomy (CHARA) have observed the expanding thermonuclear fireball from a nova that erupted last year in the constellation Delphinus with unprecedented clarity.
	Hinode satellite captures X-ray footage of solar eclipse The moon passed between the Earth and the sun on Thursday, Oct. 23. While avid stargazers in North America looked up to watch the spectacle, the best vantage point was several hundred miles above the North Pole.
	SpaceX returns to Earth loaded with lab results SpaceX's unmanned Dragon spacecraft splashed down in the Pacific Ocean on Saturday carrying a heavy load of NASA cargo and scientific samples from the International Space Station that experts hope could yield significant results.
	Google exec makes record skydive from edge of space A Google executive set a new record Friday by jumping successfully from near the top of the stratosphere—some 135,000 feet, or 41,000 meters high, his project website said.
	SpaceX ship leaves ISS for Earth loaded with lab results SpaceX's unmanned Dragon spacecraft left the International Space Station to return to Earth on Saturday after a month in orbit, NASA said.
	Orbital cargo ship readies for Monday launch Orbital Sciences Corporation's unmanned Cygnus cargo ship is preparing to launch to the International Space Station Monday, aiming to carry some 1,500 pounds (680 kilograms) of materials for space experiments.

Medicine & Health news

	Dietary cocoa flavanols reverse age-related memory decline, study shows Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. The study, published today in the advance online issue of Nature Neuroscience, provides the first direct evidence that one component of age-related memory decline in humans is caused by changes in a specific region of the brain and that this form of memory decline can be improved by a dietary intervention.
	Heart drug may help treat amyotrophic lateral sclerosis, mouse study shows Digoxin, a medication used in the treatment of heart failure, may be adaptable for the treatment of amyotrophic lateral sclerosis (ALS), a progressive, paralyzing disease, suggests new research at Washington University School of Medicine in St. Louis.
Unsuspected gene found frequently mutated in colorectal, endometrial cancers Scientists say they have identified in about 20 percent of colorectal and endometrial cancers a genetic mutation that had been overlooked in recent large, comprehensive gene searches. With this discovery, the altered gene, called RNF43, now ranks as one of the most common mutations in the two cancer types.
	Real-time readout of neurochemical activity Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals. By implanting these cells into living mammalian brains, they have shown how neurochemical signaling changes as a food reward drives learning, they report in Nature Methods online October 26.
How a tumor suppressor helps control changes in cell shape and motility that are central to metastasis Ludwig Oxford researchers have discovered a key mechanism that governs how cells of the epithelia, the soft lining of inner body cavities, shift between a rigid, highly structured and immobile state and a flexible and motile form. Published in the current issue of Nature Cell Biology, their study shows that a tumor suppressor protein named ASPP2 functions as a molecular switch that controls this process and its reverse, both of which play a critical role in a number of biological phenomena, including wound healing, embryonic development and, not least, the metastasis of cancers.
	Activity in dendrites is critical in memory formation Why do we remember some things and not others? In a unique imaging study, two Northwestern University researchers have discovered how neurons in the brain might allow some experiences to be remembered while others are forgotten. It turns out, if you want to remember something about your environment, you better involve your dendrites.
Gene link to seizures in children after MMR vaccine Scientists in Denmark said Sunday they had found genetic clues to explain why a small number of children have febrile seizures—brief convulsions—after receiving the measles, mumps and rubella (MMR) vaccine.
	New home test shakes up colon cancer screening Starting Monday, millions of people who have avoided colon cancer screenings can get a new home test that's noninvasive and doesn't require the icky preparation most other methods do.
Prognostic factors identified for peripheral squamous cell carcinomas of the lung A better survival outcome is associated with low blood levels of squamous cell carcinoma antigen, or absence of tumor invasion either into the space between the lungs and chest wall or into blood vessels of individuals with a peripheral squamous cell carcinoma, a type of non-small cell lung cancer (NSCLC).
Two US states order tough Ebola quarantine rules New York and New Jersey on Friday ordered a mandatory quarantine for medics who treated victims of Ebola in West Africa, after the deadly virus spread to America's largest city.
	Big data becomes tool in Ebola battle Nine days before Ebola was declared an epidemic, a group of researchers and computer scientists in Boston spotted the hemorrhagic fever beginning to spread in Guinea.
Roche seeks fast-track US okay of Ebola diagnostic test Swiss pharmaceutical group Roche hopes to obtain fast-track US approval for a rapid diagnostic test for Ebola, its director general said in an interview published Sunday, amid the worst-ever outbreak of the killer disease.
Genetic predisposition to elevated LDL-C associated with narrowing of the aortic valve In an analysis that included approximately 35,000 participants, genetic predisposition to elevated low-density lipoprotein cholesterol (LDL-C) was associated with aortic valve calcium and narrowing of the aortic valve, findings that support a causal association between LDL-C and aortic valve disease, according to a study appearing in JAMA. The study is being released to coincide with its presentation at the Canadian Cardiovascular Congress.
	Drugmakers bet on Ebola vaccines, treatments Drugmakers are racing to develop vaccines and drugs to address the worst outbreak of Ebola in history. It's unclear who will pay for their products, but companies are betting that governments and aid groups will foot the bill.
	New gene linked to blindness and Parkinson's disease The retinal pigment epithelium (RPE) is a tissue, which lines the back of the eye. Aging, environmental (toxic) insults and genetic predispositions contribute to the death of RPE cells in diseases, such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP), that ultimately lead to severe visual impairments or blindness.
	NY and NJ say they will require Ebola quarantines The governors of New Jersey and New York on Friday ordered a mandatory, 21-day quarantine for all doctors and other arriving travelers who have had contact with Ebola victims in West Africa.
	WHO: Number of Ebola-linked cases passes 10,000 (Update) More than 10,000 people have been infected with Ebola and nearly half of them have died, according to figures released Saturday by the World Health Organization, as the outbreak continues to spread.
	Poor health systems in Asia cause for Ebola alarm The longer the Ebola outbreak rages in West Africa, the greater chance a traveler infected with the virus touches down in an Asian city.
Teen isolated, tested for Ebola virus in Australia Australian authorities said Sunday a teenager was in isolation in hospital and undergoing tests for Ebola after she developed a fever following her arrival from Guinea.
Concerns mount over US Ebola quarantine A controversial decision to impose Ebola quarantines in three US states sparked criticism Sunday, as the first American nurse isolated under the order blasted her treatment as "inhumane."
	Expert: Quarantine causes unintended consequences Mandatory 21-day quarantines on health care workers returning from Ebola-ravaged West Africa, like those put in place by three states, can have the unintended consequence of discouraging them from volunteering, a top federal health official said Sunday.
Teen tests negative after Ebola scare in Australia Australian authorities said early Monday that a teenager who was in isolation in hospital had tested negative for Ebola after she developed a fever following her arrival from Guinea.
Medical establishment also a casualty of Ebola crisis Beyond the human tragedy of the Ebola epidemic unfolding in west Africa, the crisis is claiming a collateral victim: trust in the medical order.
