Heat from below: How the ocean is wearing down the Arctic sea ice

Science Daily - 15/06/2021
The influx of warmer water masses from the North Atlantic into the European marginal seas plays a significant role in the marked decrease in sea-ice growth, especially in winter.

Receptor location plays a key role in their function

Science Daily - 15/06/2021
Research teams have identified, for the first time, where special receptors are located on heart muscle cells. Their findings open up new perspectives for developing therapies for chronic heart failure.

New evidence of early SARS-CoV-2 infections in the United States

Science Daily - 15/06/2021
A new antibody testing study examining samples originally collected through the National Institutes of Health's All of Us Research Program found evidence of SARS-CoV-2 infections in five states earlier than had initially been reported.

COVID-19 reinfection rate less than 1 percent for those with severe illness, study finds

Science Daily - 15/06/2021
A review of more than 9,000 US patients with severe COVID-19 infection showed less than 1 percent contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test.

Plants use a blend of external influences to evolve defense mechanisms

Science Daily - 15/06/2021
Plants evolve specialized defense chemicals through the combined effects of genes, geography, demography and environmental conditions.

Rarest bee genus in North America is not so rare after all

Science Daily - 15/06/2021
Canadian researchers have discovered that a bee thought to be rarest in North America, as the only representative of its genus, is no more than an unusual specimen of a widespread species. They have reclassified the mystery bee, collected in Nevada in the 1870s, as an aberrant specimen of the California digger-cuckoo bee, a cleptoparasitic bee, with females that lay eggs in the nests of digger bees.

Healthy fat impacted by change in diet and circadian clock

Science Daily - 15/06/2021
Changing your eating habits or altering your circadian clock can impact healthy fat tissue throughout your lifespan, according to a preclinical study.

New AI model helps understand virus spread from animals to humans

Science Daily - 15/06/2021
A new model that applies artificial intelligence to carbohydrates improves the understanding of the infection process and could help predict which viruses are likely to spread from animals to humans.

From symmetry to asymmetry: The two sides of life

Science Daily - 15/06/2021
Researchers used innovative imaging techniques to demonstrate symmetric collective alignment of nuclei in the muscle cells of the anterior midgut of the Drosophila embryo. This 'collective nuclear behavior' further influences bilateral asymmetry in the development of internal organs. A clear understanding of the factors that influence the shape and location of viscera will help inform future research into experimental, and eventually therapeutic, organ regeneration technology.

Two doses of AstraZeneca offer high protection against delta variant, says Public Health England study

The Hindu:Science - 15/06/2021
In the case of Pfizer vaccine, the protection against hospitalisation was 94% after one dose and 96% after two doses.

New survey method proves Rhode Island's rarest frog may not be so rare

Science Daily - 15/06/2021
A study by researchers using a seldom-used methodology turned up many more Eastern spadefoots, an endangered primitive frog, than they expected.

Targeted drug found effective in thwarting pancreatic tumors

Science Daily - 15/06/2021
Through a pre-clinical study, researchers identified a novel drug that effectively thwarts pancreatic tumors that are addicted to the cancer-causing mutant KRAS gene.

Scientists discover how oxygen loss saps a lithium-ion battery's voltage

Science Daily - 15/06/2021
Scientists took a unique and detailed nanoscale look at how oxygen seeps out of lithium-ion battery electrodes, sapping their energy over time. The results could suggest a fix.

Research reveals why people pick certain campsites

Science Daily - 15/06/2021
Those in love with the outdoors can spend their entire lives chasing that perfect campsite. New research suggests what they are trying to find.

New research finds 1M early deaths in 2017 attributable to fossil fuel combustion

Science Daily - 15/06/2021
An international team of researchers has determined what sources contribute to pollution and the health effects they have on global, regional and smaller scales.

Introducing play to higher education reduces stress and forms deeper connection material

Science Daily - 15/06/2021
Higher education students are more engaged and motivated when they are taught using playful pedagogy rather than the traditional lecture-based method. Play also resulted in reduced stress and anxiety.

Lightning impacts edge of space in ways not previously observed

Science Daily - 15/06/2021
A team of researchers working with data collected by an Incoherent Scatter Radar (ISR) have examined the simultaneous impacts of thunderstorms and solar flares on the ionospheric D-region (often referred to as the edge of space).

Switchable mirrors from liquid metal

Science Daily - 15/06/2021
Researchers show that switching between reflective and scattering states can be achieved with just 1.4 V, about the same voltage used to light a typical LED.

New health benefits of red seaweeds unveiled

Science Daily - 15/06/2021
Red seaweeds have been prevalent in the diets of Asian communities for thousands of years. Researchers have now shown how these algae confer health benefits.

Microbes in ocean play important role in moderating Earth's temperature

Science Daily - 15/06/2021
A new study uncovers where much of the carbonate consumption in the deep sea is happening - a process that prevents its escape into Earth's atmosphere. Researchers collected and examined methane-eating microbes from seven geologically diverse seafloor seeps and found that the carbonate rocks from all sites host methane-oxidizing microbial communities with the highest rates of methane consumption.
