Responses to the COVID-19 pandemic, from school closures to lockdowns, were important for health officials and implemented even after factoring in concerns about long-term psychological effects.

If results from 2015-2020 surveys are an indication, depression cases may go up sharply in future data. In 2020, past 12‒month depression was prevalent among nearly 20 percent of adolescents and young adults, and almost 10 percent of Americans.  

'Keeping time' is easy for humans, but not all can keep time equally. Some great drummers, and even more guitarists, use a device like a metronome to keep them on a precise beat, while others seem to do it effortlessly.

A new study finds human capacity to move in synchrony with a musical beat may be partially coded in the human genome.

Scientists have confirmed the existence of lonsdaleite, a rare hexagonal form of diamond named after British crystallographer Kathleen Lonsdale, in ureilite meteorites from the mantle of a planet in our solar system.

According to the new findings, a large asteroid probably collided with the planet collided about 4.5 billion years ago, and the hexagonal structure of lonsdaleite’s atoms, making it harder than the cubic structure of terrestrial diamonds.

In 460 BC, Hippocrates described the earliest documented premenstrual syndrome, but it wasn't until 1931 that Dr. Robert Frank gave it a modern look with his paper on "premenstrual tension." In 1953 it was re-branded "premenstrual syndrome" because it covered so many symptoms. About 150.

By the early 1990s, women, and then men, were ridiculing the idea because no two women described the same thing. When a syndrome covers everything, it covers nothing, the clinical guidance notes.

Sleep apnea is a condition where people experience partial or complete obstruction of their airways during sleep and stop breathing several times a night. It can can manifest as loud snoring, gasping, choking and daytime sleepiness and is believed to affect at least 7 percent of the population.

There is correlation between that and obesity, diabetes, cigarettes, and alcohol. There is no plausible biological mechanism for why those would cause sleep apnea, it is just correlation - epidemiologists look at rows of inputs and columns of effects - and that is the problem with a new paper claiming a link to cancer. 

Quantum magnetism exploration is getting a boost from atoms about 3 billion times colder than interstellar space.

Space is cold, of course, but is warmed by the afterglow from the Big Bang. A Kyoto team instead used lasers to cool its fermions, atoms of ytterbium, within about one-billionth of a degree of absolute zero, the unattainable temperature where all motion stops, far colder than interstellar space.
