SLAC and Stanford Open One of the World's Most Advanced Facilities for Cryo-EM

Posted: 30 Apr 2018 11:30 AM PDT

Newswise imageMenlo Park, Calif. -- A new facility for cryogenic electron microscopy, or cryo-EM, has opened at the Department of Energy's SLAC National Accelerator Laboratory. Built and operated in partnership with Stanford University, it's equipped with four state-of-the-art instruments for cryo-EM, a groundbreaking technology whose rapid development over the past few years has given scientists unprecedented views of the inner workings of the cell.

Ultrafast Compression Offers New Way to Get Macromolecules into Cells

Posted: 30 Apr 2018 10:05 AM PDT

Newswise imageBy treating living cells like tiny absorbent sponges, researchers have developed a potentially new way to introduce molecules and therapeutic genes into human cells.

Geometry is Key to T-Cell Triggering

Posted: 30 Apr 2018 09:00 AM PDT

Newswise imageA new study reveals the geometric underpinnings of T-cell triggering through the precise engineering of T-cell receptor geometry in all three dimensions. The researchers used nanofabrication to create a biomimetic surface that simulates the key features of the APC, presenting T-cell receptor ligands in different geometric arrangements, with different inter-ligand spacings arranged in clusters of varying size. The results could have a significant impact on adoptive immunotherapy and the design of CAR T cells.

Bacteria's Appetite May Be Key to Cleaning Up Antibiotic Contamination

Posted: 30 Apr 2018 09:00 AM PDT

Newswise imageSome bacteria not only escape being killed by bacteria, they turn it into food. Until now, scientists have understood little about how bacteria manage to consume antibiotics safely, but new research from Washington University School of Medicine in St. Louis illuminates key steps in the process. The findings, published April 30 in Nature Chemical Biology, could lead to new ways to eliminate antibiotics from land and water, the researchers said. Environmental antibiotic contamination promotes drug resistance and undermines our ability to treat bacterial infections.

AACC Announces 2018 Award Winners; Celebrates Achievements in Laboratory Medicine

Posted: 30 Apr 2018 08:45 AM PDT

AACC, a global scientific and medical professional organization dedicated to better health through laboratory medicine, is pleased to announce the recipients of the 2018 AACC and AACC Academy Awards. These annual awards recognize laboratory medicine professionals worldwide for their exceptional research, scholarship, and service in the field, while also raising awareness that laboratory testing is essential to high quality patient care.

Down to Earth: Kansas State University Researcher Part of $3.9 Million NASA Lava Caves Study

Posted: 30 Apr 2018 08:20 AM PDT

Newswise imageWhen lava flows down the slope of a volcano, it can leave behind an extreme environment ideal for unusual microbial life and potential clues to answering the life on Mars question. Kansas State University geology professor Saugata Datta is one of the primary investigators of a new NASA study that will use a robotic vehicle to explore and collect data inside caves at Lava Beds National Monument in Northern California.

Coast Guard Develops and Tests Environmentally-Friendly Buoy Moorings

Posted: 30 Apr 2018 08:05 AM PDT

Newswise imageFrom among the proposals, S&T found a potential solution to the problem in a simple, but effective, buoy mooring system: instead of a concrete sinker and a heavy metal chain, a narrow screw anchor and an elastic rope to prevent scraping of the ocean floor was proposed and accepted.

New Technology Offers to Broaden Vision for Radio Astronomy

Posted: 30 Apr 2018 08:00 AM PDT

Newswise imageResearchers have developed a new and improved version of an unconventional radio-astronomy imaging system known as a Phased Array Feed, which can survey vast swaths of the sky and generate multiple views of astronomical objects with unparalleled efficiency.

The Changing Needs of a Cell: No Membrane? No Problem!

Posted: 30 Apr 2018 07:00 AM PDT

Newswise imageWhile the vast majority of organelles in a cell are insulated by membranes, scientists are finding more and more membrane-less organelles that form as liquid droplets nested inside of each other.

"Selfish" Gene Enhances Own Transmission at Expense of Organism's Fertility

Posted: 30 Apr 2018 07:00 AM PDT

Newswise imageResearchers recently identified a new "selfish" gene, wtf4, that encodes a toxin and an antitoxin in an effort to ensure the gene's own transmission by killing off reproductive cells lacking the gene.

Vultures reveal critical Old World flyways

Posted: 30 Apr 2018 06:00 AM PDT

Newswise imageIdentifying bottlenecks -- i.e. places where birds concentrate on migration -- helps bird conservationists know what areas to focus on and get the most bang for their buck, since a large percentage of a species' population can pass through these small areas.

NYU Receives $2.1 Million NSF Grant to Gauge Future Sea-Level Rise

Posted: 30 Apr 2018 04:00 AM PDT

Newswise imageNYU has received a $2.1 million, five-year grant from the National Science Foundation to better understand the forces behind sea-level rise--a development that has concerned scientists in recent decades because it points to the possibility of global disruptions due to climate change.
