Astronomy & Space news

	We will find organic materials on Asteroid Bennu, says OSIRIS-REx principal investigator (Phys.org)—In September 2016, NASA plans to launch its first-ever asteroid sample return mission loaded with tasks that will help us better understand the composition of asteroids, their origin, and possibly even Earth's origin. The Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) mission designed to study asteroids, which are the leftover debris from the solar system formation process, could teach us a lot about the history of the sun and planets.
	Fossil star clusters reveal their age Using a new age-dating method, an international team of astronomers has determined that ancient star clusters formed in two distinct epochs – the first 12.5 billion years ago and the second 11.5 billion years ago.
	Hubble looks in on a galactic nursery This dramatic image shows the NASA/ESA Hubble Space Telescope's view of dwarf galaxy known as NGC 1140, which lies 60 million light-years away in the constellation of Eridanus. As can be seen in this image NGC 1140 has an irregular form, much like the Large Magellanic Cloud—a small galaxy that orbits the Milky Way.
	The search for molecular oxygen among cosmic oxygen atoms Oxygen is the third most abundant element in the universe (after hydrogen and helium) and of course it is important: all known life forms require liquid water and its oxygen content. For over thirty years, astronomers have been searching for molecular oxygen, O2, as part of an accounting of cosmic oxygen atoms. Despite early predictions that O2 should be abundant in the molecular clouds that form new stars and planetary systems, it is virtually absent.
	Dust pillars of destruction reveal impact of cosmic wind on galaxy evolution Astronomers have long known that powerful cosmic winds can sometimes blow through galaxies, sweeping out interstellar material and stopping future star formation. Now they have a clearer snapshot of how it happens.
	Hiding in plain sight: Undergraduates discover the densest galaxies known Two undergraduates at San José State University have discovered two galaxies that are the densest known. Similar to ordinary globular star clusters but a hundred to a thousand times brighter, the new systems have properties intermediate in size and luminosity between galaxies and star clusters.

Medicine & Health news

	Neural efficiency hypothesis confirmed One of the big questions intelligence researchers grapple with is just how differences in intelligence are reflected in the human brain. Researchers at ETH Zurich have succeeded in studying further details relating to suspected functional differences in the brains of intelligent people.
	Sleep makes our memories more accessible, study shows Sleeping not only protects memories from being forgotten, it also makes them easier to access, according to new research from the University of Exeter and the Basque Centre for Cognition, Brain and Language. The findings suggest that after sleep we are more likely to recall facts which we could not remember while still awake.
	Why Alfred Hitchcock grabs your attention: Researchers identify neural signature of tunnel vision The movies of Alfred Hitchcock have made palms sweat and pulses race for more than 65 years. Georgia Institute of Technology researchers have now learned how the Master of Suspense affects audiences' brains. Their study measured brain activity while people watched clips from Hitchcock and other suspenseful films. During high suspense moments, the brain narrows what people see and focuses their attention on the story. During less suspenseful moments of the film clips, viewers devote more attention to their surroundings.
	Study finds non-genetic cancer mechanism Cancer can be caused solely by protein imbalances within cells, a study of ovarian cancer has found.

	Study may show a way to predict whether children with a genetic disorder will develop autism or psychosis Doctors and researchers have long known that children who are missing about 60 genes on a certain chromosome are at a significantly elevated risk for developing either a disorder on the autism spectrum or psychosis—that is, any mental disorder characterized by delusions and hallucinations, including schizophrenia. But there has been no way to predict which child with the abnormality might be at risk for which disorder.
	Taking an interdisciplinary approach to exploring motor function The simple actions that humans make and take for granted every day are visible results of complex, unseen engineering at work: neuron-activated muscles throughout the body generate forces for movement, with each movement particular to each individual, influenced by a staggering number of potential neuromechanical solutions.
	In CRISPR advance, scientists successfully edit human T cells In a project spearheaded by investigators at UC San Francisco, scientists have devised a new strategy to precisely modify human T cells using the genome-editing system known as CRISPR/Cas9. Because these immune-system cells play important roles in a wide range of diseases, from diabetes to AIDS to cancer, the achievement provides a versatile new tool for research on T cell function, as well as a path toward CRISPR/Cas9-based therapies for many serious health problems.
	Gene therapy may improve survival of patients with recurrent ovarian cancer Use of gene therapy to deliver a protein that suppresses the development of female reproductive organs may improve the survival of patients with ovarian cancer that has recurred after chemotherapy, which happens 70 percent of the time and is invariably fatal. In their report receiving online publication in PNAS Early Edition, a Massachusetts General Hospital (MGH) research team describes how a single injection of a modified version of Mullerian Inhibiting Substance, a protein critical to sexual development, carried on a commonly used viral vector suppressed the growth of chemotherapy-resistant ovarian tumors in a mouse model. While not all the tested tumors - grown from cells grafted from patient tumors - were sensitive to this treatment, the investigators also outline a noninvasive way of screening cancer cells in vitro for treatment responsiveness.
New technique to map hormone levels in near real-time could help surgeons detect and remove tumors with precision As many as 20 percent of people may have a benign cyst or tumor in their pituitary gland. The vast majority of pituitary tumors are noncancerous, but can cause headaches and profound fatigue, and can also disrupt hormone function. Currently, surgeons rely on radiologic images and MRIs to gather information about the size and shape of the tumor, but the resolution of such imaging technologies is limited, and additional surgeries to remove more of the tumor may be needed if a patient's symptoms persist. In a new study published in the Proceedings of the National Academy of Sciences on July 27, investigators from Brigham and Women's Hospital (BWH) present a new technique that could help surgeons more precisely define the locations of tumors in near real-time.
	In mice, experimental drug treatment for Rett syndrome suggests the disorder is reversible A team at Cold Spring Harbor Laboratory (CSHL) has developed a strikingly new approach for treating Rett syndrome, a devastating autism spectrum disorder (ASD) that affects 1 in 10,000 people in the US, mostly girls. In a paper appearing online today in the Journal of Clinical Investigation, Professor Nicholas Tonks, FRS, and colleagues, demonstrate that treatment with small-molecule drug candidates significantly extends lifespan in male mice that model Rett syndrome and ameliorates several behavioral symptoms of the disorder in model female mice.
	Flow means 'go' for proper lymph system development The lymphatic system provides a slow flow of fluid from our organs and tissues into the bloodstream. It returns fluid and proteins that leak from blood vessels, provides passage for immune and inflammatory cells from the tissues to the blood, and hosts key niches for immune cells. How this system develops hasn't been well understood, but now researchers from the Perelman School of Medicine at the University of Pennsylvania have found from experiments in mice that the early flow of lymph fluid is a critical factor in the development of mature lymphatic vessels.
	Babies' brains show that social skills linked to second language learning Babies learn language best by interacting with people rather than passively through a video or audio recording. But it's been unclear what aspects of social interactions make them so important for learning.

Biology news

	Driving myelination by actin disassembly (Phys.org)—If a metallurgist wanted to determine how a blade was made they might cut a small cross section, mount, polish, and etch it, and then look at it under a microscope. They could probably tell right away whether it was forged, cast, or perhaps even 3D printed. If the blade was of a particularly high quality, like a Samurai sword, they could see the multiple layers that were created the through laborious cycles of heating, hammering and refolding that are typically used to optimize the grain structure for both toughness, hardness, and grain orientation. The point here is that the structure evident in the Samurai sword cross section didn't just passively polymerize out of thin air like a snowflake, or get made by some other passive thermochemical series of events, it took a more directed driving force.
	Some vaccines support evolution of more-virulent viruses Scientific experiments with the herpesvirus such as the one that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of severe illness. The research has important implications for food-chain security and food-chain economics, as well as for other diseases that affect humans and agricultural animals.

	Classifying microbial species in the genomics era The rapid explosion in the throughput of DNA sequencing due to new technology platforms is fueling an increase in the number of sequenced microbial genomes and driving much greater availability of these data to the research community. Traditionally, identifying the microorganisms selected for sequencing is often decided on the basis of a single universal marker gene. More recently, however, researchers have noticed that the identity of microbes for which whole-genome information has become available does not always match up with the identity determined by the approaches commonly used prior to the advent of next-generation high-throughput sequencing.
	Humpback whales make a comeback in Australian waters A review of the scientific research on the recovery of Australia's humpback whale populations has revealed that they are increasing at a remarkable rate and that the increase is among the highest documented worldwide, according to a paper published in the journal, Marine Policy.
	Essential parts of the polar bear Y chromosome decoded For the first time, a team of scientists, led by Prof. Axel Janke of the Senckenberg Research Center for Biodiversity and Climate, reconstructed part of the male chromosome in polar bears. The scientists were able to assign 1.9 million base pairs specifically to the polar bear Y chromosome. In their study, published today in the scientific journal Genome Biology and Evolution, they show that more than 100,000 years ago, the male polar bear lineages split and developed in two separate genetic groups.
Half of Columbia River sockeye salmon dying due to hot water More than a quarter million sockeye salmon returning from the ocean to spawn are either dead or dying in the Columbia River and its tributaries due to warming water temperatures.
Mosquito spraying in South Florida scaled back to protect rare butterflies In the annual battle to rid steamy South Florida of swarming summer mosquitoes, new research has found routine spraying may pose a far greater risk to an innocent bystander: butterflies.
	Scientists study predator-prey behavior between sharks and turtles A new collaborative study led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science & Abess Center for Ecosystem Science & Policy examined predator-prey interactions between tiger sharks and sea turtles off the northwestern Atlantic Ocean.
Grand Canyon biologist sets up cameras to document wildlife A biologist has installed more than two dozen motion-sensing cameras along a 50-mile stretch of the Grand Canyon in pursuit of images of an elusive skunk species.
