Algorithm leads to a dramatic improvement in drug discovery methods

Antibiotics for treating particularly resistant diseases, molecules that block immune system overreactions, molecules that inhibit the growth of cancer cells by removing excess iron, molecules that may increase the digestion of fats: all these and more have been discovered in recent years using a unique computerized approach to solving particularly complex problems.

Camera captures microscopic holograms at femtosecond speeds

Researchers from ITMO University have built a setup for recording holograms of tiny objects like living cells at femtosecond speeds. The new method reconstructs the phase topography of a sample according to deformations that emerge in a laser pulse when it passes through the specimen. Show More Summary

Simulated honeybees can use simple brain circuits for complex learning

Honeybees may not need key brain structures known as mushroom bodies in order to learn complex associations between odors and rewards, according to new research published in PLOS Computational Biology.

ACR acknowledges CMS efforts to increase flexibility and reduce regulatory burdens

(American College of Rheumatology) The American College of Rheumatology (ACR) today welcomed components of a new proposed rule from the Centers for Medicare & Medicaid Services (CMS) regarding the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) Quality Payment Program (QPP) as containing several positive developments for rheumatology providers.

Tourette Syndrome risk increases in people with genetic copy variations

(Purdue University) An international team that just conducted the largest study of Tourette Syndrome has identified genetic abnormalities that are the first definitive risk genes for the disorder.

Ecology insights improve plant biomass degradation by microorganisms

Microbes are widely used to break down plant biomass into sugars, which can be used as sustainable building blocks for novel biocompounds. Getting the right microbial community for this process is still a matter of trial and error. New...Show More Summary

Planetary Society volunteers host SpaceUp London 2017

Earlier this month, The Planetary Society brought together space enthusiasts at Queen Mary University of London for “SpaceUp London 2017”—the first large-scale event organized by Planetary Society volunteers in Europe.

Research suggests sexual appeals in ads don't sell brands, products

(University of Illinois at Urbana-Champaign) Ads with sexual appeals are more likely to be remembered but don't sell the brand or product, according to a meta-analysis of nearly 80 advertising studies, published online this week by the International Journal of Advertising. Show More Summary

Synopsis: Laser Stars Under the Lens

Raman scattering could contaminate astronomical observations that use artificial, laser-generated “stars” to correct for the effect of atmospheric turbulence. [Physics] Published Thu Jun 22, 2017

Synopsis: Sensing Earthly Magnetic Fields

An organic material’s resistance changes measurably in weak magnetic fields, with a sensitivity similar to that of migrating birds. [Physics] Published Thu Jun 22, 2017

Patient-inspired research uncovers new link to rare disorder

(Baylor College of Medicine) Peroxisomal biogenesis disorder, which has been linked only to lipid metabolism, is also associated with sugar metabolism.

Mouse study suggests how hearing a warning sound turns into fearing it over time

(Emory Health Sciences) An adult mouse model reveals that changes in lattice-like structures in the brain known as perineuronal nets are necessary to 'capture' an auditory fear association and 'haul' it in as a longer-term memory.

Bacterial organizational complexities revealed

(Michigan State University) For the first time, scientists have visualized the fine details of bacterial microcompartment shells -- the organisms' submicroscopic nanoreactors, which are comprised completely of protein.

Cells in fish's spinal discs repair themselves

Duke researchers have discovered a unique repair mechanism in the developing backbone of zebrafish that could give insight into why spinal discs of longer-lived organisms like humans degenerate with age.

Blob-Like Intruders Infesting Pacific Coast

They are called "unicorns of the sea" and they are infesting the Pacific Coast, destroying fishing nets and puzzling scientists, the Guardian reports. The tiny blob-like creatures are infesting some stretches of the West Coast as far north as Alaska so badly that fishermen can't catch anything. The translucent tubular...

Study examines gun policy preferences across racial groups

(University of Illinois at Chicago) Support for all forms of gun control is stronger among Latinos and blacks than whites, according to researchers from the University of Illinois at Chicago.

A rising star

(University of California - Santa Barbara) It's a tiny marine invertebrate, no more than 3 millimeters in size. But closely related to humans, Botryllus schlosseri might hold the key to new treatments for cancer and a host of vascular diseases.

NASA's Webb telescope gets freezing summertime lodging in Houston

(NASA/Goddard Space Flight Center) NASA's James Webb Space Telescope was placed in Johnson Space Center's historic Chamber A on June 20, 2017, to prepare for its final three months of testing in a cryogenic vacuum that mimics temperatures in space.

Rare cells are 'window into the gut' for the nervous system

Specialized cells in the gut sense potentially noxious chemicals and trigger electrical impulses in nearby nerve fibers, according to a new study led by UC San Francisco scientists. "These cells are sensors, like a window looking into the contents of the gut," said James Bayrer, MD, PhD, an assistant professor of pediatrics at UCSF and one of the lead authors of the paper.

Proton pump inhibitors do not contribute to dementia or Alzheimer's disease

(American Geriatrics Society) Noting that the prescription of proton pump inhibitors is on the rise among middle-aged and older adults, a team of researchers designed a new study to examine PPIs and the risk of dementia, mild cognitive impairment, and Alzheimer's disease. They published their study in the Journal of the American Geriatrics Society.
