Sea Ice in Arctic Coastal Regions are Thinning Faster Than Previously Thought According to a new modeling study headed by researchers from the , sea ice in the Arctic coastal regions may be thinning up to twice as fast as previously assumed.

The thickness of sea ice is deduced by quantifying the height of the ice above the water, but this measurement is affected by snow weighing the ice floe down. To adjust this measurement,...

A new study published in the journal Stem Cell Reports by University of Alberta researchers is shedding light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues.

Conversations in social media platform can provide new way to communicate vaccine efficacy In the early days of COVID-19 vaccine development, a new social media platform provided a place for like-minded people to discuss vaccines, share misinformation and speculate about the motivations for its development. A new study from the University of Kansas shows people flocked to Parler to discuss the vaccines in an echo chamber-type environment, and those conversations can shed light about how to communicate about vaccine efficacy during health crises. COVID-19 vaccine vial and syringe photo from th...

New Mechanism Enables Superconductivity, Magnetism to Co-Exist in Same Material Written by AZoMJun 2 2021 Physicists from the University of Bath, in association with scientists from the United States, have revealed a novel mechanism that allows superconductivity and magnetism to exist together in the same material. On the left: a crystal coated in gold—the gold coating allows the magnetic imaging tool to get within nanometers of the material’s surface. On the right: a magnetic picture of a segment of the crystal showing the vortices (dark holes) that were studied. Image Credit: University...

Patterns of Climate Change Drove Early Human Evolution Written by AZoCleantechJun 1 2021 Headed by Dr Stefanie Kaboth-Bahr from the University of Potsdam, a scientific consortium has discovered that prehistoric El Niño-like weather patterns were mainly responsible for causing the environmental change in the sub-Saharan African region over the past 620 thousand years—the crucial timeframe for human evolution. Today a saline mudflat, the Chew Bahir Basin in southern Ethiopia once held an extensive paleo-lake during humid phases. Scientific deep drilling from the current playa surface produce...
