After three hours of tests and more than 100 flushes, the team detected droplets smaller than 3 mm in size at a height of 1.5 m above a toilet or urinal (face height for many people) and found that the droplets persisted at that height for more than 20 seconds after the flush. The 10 quirkiest stories from the world of physics in 2021
I found that those who called themselves feminists reported having more recently masturbated than non-feminist women. In addition, I found that in partnered sexual encounters, feminists were more likely to participate in anal play, as well as engage in more kissing, cuddling, and massage than non-feminists. I also found that feminist women were more likely to receive oral sex than non-feminists.
Rather than being highly selective, people appear to have a tendency to push relationships forward, even when things are not going well.
He pops a Viagra, straightens out the bed cover, showers and, when he’s ready, calls for Anne. [...] The missionary position no longer works for them — David has put on weight and would be too heavy. Instead, he often lies behind Anne and puts one leg between hers, the other to the side. [...] During oral sex, David stops just when Anne is on the verge of climaxing. [...] Even with Viagra, David can’t always have a full erection, but they usually have intercourse regardless; sometimes he has a dry orgasm, where he doesn’t produce enough semen to ejaculate. [...] David and Anne are in their 80s now, and they recently told me that at this stage of life, sex is the best it has ever been. [NY Times]
USC team shows how memories are stored in the brain, with potential impact on conditions like PTSD. Contrary to expectations, the study in larval zebrafish shows synapses in one part of the brain are eliminated and new ones are created in a different region when memories are formed. These major structural changes could account for memory formation.
How do they keep blood flowing during heart transplant? You'll receive medication that causes you to sleep (general anesthetic) before the procedure. Your surgeons will connect you to a heart-lung bypass machine to keep oxygen-rich blood flowing throughout your body. This machine does the work of your heart and lungs while they are stopped. Your surgeon will make an incision in your chest. Your surgeon will separate your chest bone and open your rib cage so that he or she can operate on your heart. Your surgeon then removes the diseased heart and sews the donor heart into place. He or she then attaches the major blood vessels to the donor heart. The new heart often starts beating when blood flow is restored. Sometimes an electric shock is needed to make the donor heart beat properly.
the military has four extra telephone buttons that they don't tell us about [..] AUTOVON phones thus feature a full 4x4 keypad, with the rightmost column typically in red and used to prefix dialed calls with a precedence level.

The heaviest drinkers in the animal kingdom are punier than you might expect. Elephants, for example, are massive, but they are relative lightweights—they lack a gene for alcohol metabolism. Humans actually rank pretty highly, thanks to our ancestors’ propensity for picking fermented fruit off the ground. But to find the real champs, you have to think smaller.
