A new mode of how antibodies navigate the surface of pathogens like coronaviruses compares the migration of these pathogen hunters to the random movements of a child on stepping stones.

Antibodies are often thought of as Y-shaped proteins but perhaps a more accurate way to envision them is to flip the picture upside down and regard antibodies as walking stick figures, stepping on antigens. Those two characteristic “Y” branches function as legs of sorts.

No one will miss the COVID-19 pandemic. Except maybe greenhouses.

New surveys show about one out of every three people began gardening in 2020 because they were home more due to SARS-CoV-2 restrictions and worries. Many also put in new grass lawns and did outdoor renovations, such as installing new plant beds and other landscaping.

With war in Ukraine, Europeans are worried a key source of their food, Russia and Ukraine, is at risk.

They are right to be concerned. Food is a strategic resource but European countries chose to embrace higher cost lower yield alternatives to modern agriculture at home because they got cheap food from the east.

If an additional 290,000,000,000 loaves of bread were available, that would ease the strain worldwide. That is how much wheat is lost each year due to pests and diseases that the so-called organic process can't prevent. But science can.

"Live cold, die old" may soon become folk wisdom if a new study holds up in mice is true for people.

Most of us have heard some form of the phrase "live fast, die young" and take it to mean reckless behavior leads to premature death. It certainly does in epidemiology but in science it means that animals with high metabolic rates ("living fast") tend to die sooner than those with slow metabolism. They burn out rather than fade away.

The public are often baffled why environmental journalists attend climate conferences in person, using the rationalization that they do their jobs better if they can talk to people outside formal interviews.

What salesperson doesn't feel the same way? 

Science conferences are also well-attended, groups hosting them even note their high attendance, but the belief that any benefit from flying there and staying in a hotel is meaningful is usually held by people who enjoy going to conferences rather than empirical data. 

A small pilot study has concluded that even one night of exposure to moderate room lighting during sleep can impair glucose and cardiovascular regulation.

In the experiment, 10 people slept for one night in dim light followed by one night with overhead room lighting while another 10 slept for two nights in dim light.
