A quick electrical test is as good as a person’s taste buds at determining the strength and roast of a cup of coffee

Ha muerto Craig Venter a los 79 años, un científico irrepetible y empresario, que lideró la parte privada del proyecto Genoma Humano desde su empresa Celera Genomics y que incluyó su propio ADN en el genoma resultante. Lo explico en @sciencemedia_es

Sperm have long been thought of as streamlined DNA delivery vehicles, carrying little more than a father’s genes to the egg.
But a new study shows that in mice, sperm may transmit the father’s influence in another way.
During their passage through the epididymis, the coiled tube where they mature after leaving the testes, sperm pick up messenger RNAs (mRNAs), RNA transcripts of genes that contain the genetic instructions for making proteins.
These mRNAs seem to be transferred to the fertilized egg, where they may affect the developing embryo.

Among the most agile of flying creatures, dragonflies have evolved to perform quick aerial maneuvers—akin to planes in a dogfight—both to attract mates and to catch prey midair.
Last year, researchers documented and explained a unique stunt the insects perform so quickly most people never see it.
Every few minutes, a dragonfly dives into water and takes off again, turning several forward somersaults as it ascends.
The purpose of the behavior? The quick dip cools the insect down, and the loop-the-loops help it dry off by flicking away the water.

Rafael Nadal was diagnosed with Müller-Weiss syndrome at 19 years old. The navicular bone in his left foot was collapsing. There is no cure. The condition is degenerative. It only gets worse.
The navicular is the keystone of the human foot. It catches the head of the talus and connects to the first three toes. It absorbs the majority of load when you change direction. In tennis, players change direction hundreds of times per match. On clay, where the surface forces you to slide into every shot, the stress on that bone multiplies.
His sport demands exactly the one thing his body could no longer do without pain.
He won 22 Grand Slams after the diagnosis. Fourteen of them at Roland Garros, the clay court tournament that punished his foot the hardest. His record there: 112 wins, 4 losses. A 97% win rate across 23 years at the single venue that required the most from the bone that was failing him.
For context, the other Grand Slam dominance records: Djokovic at the Australian Open has a 91% win rate. Federer at Wimbledon had 88%. Nadal's 97% at Roland Garros isn't just the best in tennis. There may not be a comparable number in any individual sport at any single venue, ever.
He once told reporters he doesn't remember what the feeling of playing without pain is. The condition is most common in women aged 40 to 60. He got it at 19 and kept winning for 19 more years.
The Rafa documentary drops May 29. During the French Open. The tournament he won 14 times will be happening without him while 300 million subscribers watch what it actually cost him to own it. He turns 40 on June 3.
Netflix timed this so the stadium that was his is full of players trying to fill a void that 97% says might be permanent.
