Amazon.com Inc. Chief Executive Jeff Bezos sold roughly $5 billion worth of shares in his company this week, his largest concentrated disposal of shares since his divorce.
According to filings with the Securities and Exchange Commission, Bezos sold roughly 1.48 million shares in separate transactions Monday through Thursday, with proceeds of $4.91 billion, according to tabulations performed by Dow Jones Market Data group. The stock sales were prearranged through a 10b5-1 trading plan, according to the filings.
Researchers from Wageningen University in the Dutch town of Lelystad announced recently that they had successfully taught bees to “extend their tongues when they smell the coronavirus”. Bees have a sense of smell 50 times better than that of dogs, whose olfactory responses are already orders of magnitude more receptive than humans’.
They achieved the result via using the technique of conditioning. The researchers stated that “each time the bees were exposed to the scent from an infected sample, they received a sugar water solution reward.” They go on to say that “by repeating this action several times, the bees associated the sugar reward with the scent as the stimulus.”
Once successfully trained to stick their tongues out when exposed to the coronavirus-positive samples and subsequent sugar water reward, the bees eventually began performing the action even when the reward was not given.
