A recent study found that vaccination with two doses of the Pfizer-BioNTech COVID-19 vaccine resulted in immune cell response considerably lower in people with prior SARS-CoV-2 infection than those without.

The level of this key immune cell that targets the SARS-CoV-2 spike protein, CD8+ T, was substantially lower in unvaccinated people with COVID-19 than in vaccinated people who had never been infected. People who recover from SARS-CoV-2 infection and then get vaccinated are more protected than people who are unvaccinated and the new paper suggests that the virus damages an important immune-cell response.

In 2014, a new invasive species from Asia was detected in Pennsylvania, but by the time government knows about it, it is too late and spotted lanternflies have since spread to more than 100 counties across 14 states. 

Some companies profited during the government lockdowns and then lingering social stigma about being outside the home. Exercise bikes, office furniture, and coffee machines all did well.

It will be decades before we know how many have been impacted in ways that were unanticipated. Being at home, for example, should have given more time to exercise, yet it often did the opposite. Despair, prevalent media discussing disaster in real time, and social isolation don't lead to a desire to exercise in some.

President Biden issued another slap to those oil-guzzling Republicans intent on ruining Gaia, or he enraged environmentalists by letting oil-guzzling Republicans ruin bucolic Alaska, all in one day.

Even in the same minute.

Which was it? Neither, and that is a problem with corporate media. To get you to see an ad and get them paid they have to write a headline that is most appealing to you - and if you are someone in the middle, you quickly receive both.

These days I am spending a few months in northern Sweden, to start a collaboration with computer scientists and physicists from Lulea University of Technology on neuromorphic computing (I'll soon write about that, stay tuned). The rather cold weather of March (sub-zero temperatures throughout the day) is compensated by having access to the night show of northern lights, which are often visible from these latitudes (66 degrees north).

Athletes use custom-​made insoles because they know a fraction of a second can make the difference between victory and defeat, but to do that specialists must first create a pressure profile of the feet. Athletes walk barefoot over pressure-​sensitive mats, where they leave their individual footprints and then orthopedists create customized insoles by hand.

The optimization and adjustment takes a lot of time and if you are a wealthy elite, the money is less of a worry but for people with musculoskeletal pain the cost may be out of reach.

Water is over 70 percent of the surface of the earth but how that came to be, through what mix of random chance and extraterrestrial involvement, has been a debate. Earth is a relatively small planet and relatively near its star so creating large surface oceans is difficult.

A new study analyzed melted meteorites that had been floating around in space since the solar system’s formation four and a half billion years ago and found they had extremely low water content, among the driest extraterrestrial materials ever measured. This led them to conclude that water was likely delivered to Earth via unmelted, or chondritic, meteorites. 

An analysis of over 4,300,000 patients in 8,119 161 primary care visits found that publicly insured people, those using the Affordable Care Act public exchanges subsidized by government, were more likely to be given inappropriate antibiotic prescribing in cases of upper respiratory tract infections and opioids and benzodiazepines for patients with pain symptoms. 

The reason is that doctors may be unable to spend enough time with them.

A new study reports abnormalities in functional neural networks of dogs diagnosed with anxiety. Compared with healthy dogs, those with anxiety exhibit stronger connections between the amygdala and other regions of the anxiety network.

Venus is similar to Earth in size and mass but does not have plate tectonics, which are the primary locations of volcanic activity. A lingering question has always been if there is volcanic activity anyway.
