A chemical compound found in liverworts may provide the pain and inflammation relief of pot’s THC but without the same kind of high.
Both the molecule, called perrottetinene, and tetrahydrocannabinol, or THC — the mind-altering substance found in marijuana — have similar molecular structures. Lab tests with human brain cells and in mice have revealed that, like THC, perrottetinene easily...
A tiny weed that slithers up through sidewalk cracks is helping scientists understand the sacrifices that plants make to protect themselves from pests.
Most plants combat insects and other herbivores by sending out bitter chemicals through their leaves. Now by studying thale cress (Arabidopsis thaliana), a commonly found member of the mustard family, researchers found that energy spent...
When you’re essentially a little ball of floof, flying is hard.
To ride the wind, dandelion seeds stir up a weird type of whirlpool in the air directly above them. The newly discovered way of moving through the air, described October 17 in Nature, resolves a long-standing question about how the seeds stay aloft.
Dandelion seed flight is not unlike the flight of Mary Poppins:...
550-year-old seed sprouts —
A seed of the South America herb achira (Canna sp.), taken from an ancient Indian necklace, has germinated, and the young plant is growing well.… Carbon-14 dating of bones at the site sets the seeds’ age at about 550 years.… The plant from the old seed appeared to have a disturbed gravity orientation, but is still growing fairly normally. — Science News...
It’s a lovely notion, but tricky to prove. Still, lemurs sniffing around wild fruits in Madagascar are bolstering the idea that animal noses contributed to the evolution of aromas of fruity ripeness.
The idea sounds simple, says evolutionary ecologist Omer Nevo of the University of Ulm in Germany. Plants can use mouth-watering scents to lure animals to eat fruits, and thus spread around...
