Managing global climate change--and local conditions--key to coral reefs' survival

Eurekalert - May 27 2021 - 00:05
According to a new study, "Local conditions magnify coral loss after marine heatwaves," published in the journal Science, what's key to coral reefs surviving climate-driven heatwaves and subsequent bleaching is managing global climate change--and local conditions.

Seabirds' success reveals asymmetry in ocean health

Eurekalert - May 27 2021 - 00:05
In a study that uniquely evaluates marine ecosystem responses to a changing climate by hemisphere, researchers report that the fish-eating, surface-foraging bird species of the Northern Hemisphere suffered greater breeding productivity stresses over the last half-century than their Southern Hemisphere counterparts.

Seabirds sound alarm: Breeding success corresponds to hemispheric rates of ocean warming

Eurekalert - May 27 2021 - 00:05
Some seabirds are struggling to raise young where the globe is most rapidly warming - in the northern hemisphere, according to a study published in the journal Science. The research was undertaken by an international team of 40 scientists led by Farallon Institute in California.

Reducing metabolic cost of walking while generating electricity using an exoskeleton

Eurekalert - May 27 2021 - 00:05
An exoskeleton can reduce the metabolic cost of walking not by adding energy or by recycling energy from one gait phase to another, as other exoskeletons have done, but by removing the kinetic energy of a striding person's swinging leg so they don't have to tense their muscles so much.

Local management crucial to helping coral reefs survive warming waters

Eurekalert - May 27 2021 - 00:05
Local management of coral reefs to ease environmental stressors, such as overfishing or pollution, could increase reefs' chances of recovery after devastating coral bleaching events caused by climate change, a new study finds.

Scientists overhear two atoms chatting

Eurekalert - May 27 2021 - 00:05
How materials behave depends on the interactions between countless atoms. You could see this as a giant group chat in which atoms are continuously exchanging quantum information. Researchers from Delft University of Technology in collaboration with RWTH Aachen University and the Research Center Jülich have now been able to intercept a chat between two atoms. They present their findings in Science on 28 May.

DNA vaccines for COVID-19 effective in mice, hamsters

Eurekalert - May 27 2021 - 00:05
Currently available COVID-19 vaccines rely on mRNA strands to teach the human immune system to recognize the SARS-CoV-2 virus. Now, researchers reporting in PLOS Neglected Tropical Diseases have reported the successful development of a vaccine that instead uses DNA encoding the virus' spike protein.

Mass gatherings during Malaysian election directly and indirectly boosted COVID-19 spread

Eurekalert - May 27 2021 - 00:05
New estimates suggest that mass gatherings during an election in the Malaysian state of Sabah directly caused 70 percent of COVID-19 cases detected in Sabah after the election, and indirectly caused 64.4 percent of cases elsewhere in Malaysia. Jue Tao Lim of the National University of Singapore, Kenwin Maung of the University of Rochester, New York, and colleagues present these findings in the open-access journal PLOS Computational Biology.

Fight against antibiotic-resistant bacteria has a glowing new weapon

Eurekalert - May 27 2021 - 00:05
In the perpetual arms races between bacteria and human-made antibiotics, there is a new tool to give human medicine the edge, in part by revealing bacterial weaknesses and potentially by leading to more targeted or new treatments for bacterial infections.

Not fear, but goal importance and others' behavior makes you favour COVID-19 measures

Eurekalert - May 27 2021 - 00:05
Fear that you are at particularly lethal risk of COVID-19 infection might not be quite as strong of motivation to support strict government regulations and drastically change your lifestyle as your perception of whether others are doing enough to fight COVID-19, concludes a new study looking into data from the United Kingdom and Switzerland. The research paper is published in the peer-reviewed scientific journal Social Psychological Bulletin.

Climate skeptics not easily persuaded by available evidence, now or later

Eurekalert - May 27 2021 - 00:05
Climate skeptics who aren't persuaded by the existing evidence from climate change are unlikely to change their minds for many years, according to a newly published quantitative study by a University of Oregon environmental economist, The central question posed by the study published in the journal Climate Change was "How much evidence would it take to convince skeptics that they are wrong?"

Shedding new light: A new type of immunosensor for immunoassay tests

Eurekalert - May 27 2021 - 00:05
Immunoassays have emerged as an immensely reliable means of detection in fields ranging from biological research to food safety management. In a recent study, scientists at Tokyo Institute of Technology (Tokyo Tech) developed a new type of immunosensor for these purposes. Termed "BRET Q-body", the sensor works on the principle of bioluminescence resonance energy transfer (BRET) and can be used to detect antigens without the need for an external light source, greatly simplifying immunoassays.

Researchers develop technique to functionally identify and sequence soil bacteria one cell at a time

Eurekalert - May 27 2021 - 00:05
A new, extremely precise technique, developed by the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences, allows the identification of the metabolic function and genome of soil bacteria one bacterial cell at a time instead of having to analyze millions all at once.

The robot smiled back

Eurekalert - May 27 2021 - 00:05
Long interested in interactions between robots and humans, Columbia Engineering researchers have created EVA, a new autonomous robot with a soft and expressive face that responds to match the expressions of nearby humans. "The idea for EVA took shape a few years ago, when my students and I began to notice that the robots in our lab were staring back at us through plastic, googly eyes," said Prof Hod Lipson, who led the team.

Comprehensive electronic-structure methods review featured in Nature Materials

Eurekalert - May 27 2021 - 00:05
Nicola Marzari, head of EPFL's THEOS lab and director of NCCR MARVEL, has published with Andrea Ferretti and Chris Wolverton a review of electronic-structure methods as part of a special edition Insight from Nature Materials. It gives an overview of the methods, application to the prediction of materials properties, and examines strategies targeting broader goals of materials design and discovery. The authors consider emerging challenges in predictive accuracy and addressing real-life complexity.

Genetic risk factors revealed by largest genome study of depression to date

Eurekalert - May 27 2021 - 00:05
In the largest genetic analysis of depression to date, Veterans Affairs researchers identified many new gene variants that increase the risk for depression. The groundbreaking study helps researchers better understand the biological basis of depression and could lead to better drug treatments. The study involved genetic data on more than 300,000 participants of VA's Million Veteran Program (MVP), along with more than a million subjects from other biobanks, including 23andMe.

Benefits of immunotherapy combination persist for more than six years in advanced melanoma

Eurekalert - May 27 2021 - 00:05
In the longest follow-up results from a clinical trial of combination immunotherapy for metastatic melanoma, investigators report that nearly half the patients who received the drugs nivolumab and ipilimumab were alive a median of six and a half years after treatment. The results, stemming from the CheckMate 067 clinical trial, represent a new landmark in survival rates for patients with melanoma treated with immune checkpoint inhibitor drugs.
