One of the physiopathological characteristics of COVID-19 that has most baffled the scientific and medical community is what is known as “silent hypoxemia” or “happy hypoxia”. Patients suffering this phenomenon, the causes of which are still unknown, have severe pneumonia with markedly decreased arterial blood oxygen levels (known as hypoxemia). However, they do not report […]
The bizarre features of this mammal have scientists perplexed as to how it could have evolved; “it bends and even breaks a lot of rules” New research published today in the Journal of Vertebrate Paleontology describes a bizarre 66 million-year-old mammal that provides profound new insights into the evolutionary history of mammals from the southern supercontinent Gondwana […]
A study published in Nature Neuroscience shows how spike protein crosses the blood-brain barrier More and more evidence is coming out that people with COVID-19 are suffering from cognitive effects, such as brain fog and fatigue. And researchers are discovering why. The SARS-CoV-2 virus, like many viruses before it, is bad news for the brain. […]
On Dec. 21 at 1:02 a.m. Alaska time, this big round head of a planet will tip back, pause, then slowly nod toward the sun. That breathless moment of stillness is the northern hemisphere’s winter solstice. Solstice is a combination of a few Latin words, meaning “sun stands still.” That is somewhat true from this […]

When Polar Star’s annual resupply mission at McMurdo Station in Antarctica was cancelled due to COVID safety precautions at the station, Coast Guard leaders seized the opportunity to coordinate […]

The American blue economy, which are resources and services provided by the oceans, contributed about $373 billion to the economy in 2018, and fisheries play a large role in that. Climate change, however, threatens commercial and recreational fisheries; changes in water temperature can affect the environments where fish, shellfish, and other marine species live, and cause them […]
Washington, DC— A small group of volcanic islands in Alaska’s Aleutian chain could actually be part of a single, previously unrecognized giant volcano in the same category as Yellowstone, according to work from a research team, including Carnegie’s Diana Roman, Lara Wagner, Hélène Le Mével, and Daniel Portner, as well as recently departed postdoc Helen Janiszewski […]
