To Be a Genius, Think Like a 94-Year-Old (Aaron M.)
On the contrary, there’s plenty of evidence to suggest that late blooming is no anomaly. A 2016 Information Technology and Innovation Foundation study found that inventors peak in their late 40s and tend to be highly productive in the last half of their careers. Similarly, professors at the Georgia Institute of Technology and Hitotsubashi University in Japan, who studied data about patent holders, found that, in the United States, the average inventor sends in his or her application to the patent office at age 47, and that the highest-value patents often come from the oldest inventors — those over the age of 55.
What the researchers found at the site, dubbed Cerutti Mastodon, looks very much like a perfectly preserved tableau of an ancient tool-making workshop. Stone “anvils,” or flat rocks, are surrounded by a scattering of smaller “cobbles” used as hammers. Mixed in with these items are shattered mastodon bones and teeth, many of them crushed in a way that could only be done by a human with a stone tool. It’s clear that the stones were deliberately struck against each other because there are stone flakes that perfectly fit into the cobble hammers, possibly broken off while the bones were being worked. The breaks and scoring marks on the bones suggest that people were breaking them open to get at the marrow, as well as crafting them into tools.
Bright future for self-charging batteries (blackeagle)
The study shows that a standard cathode from a lithium-ion battery can be “sensitized” to light by incorporating photo-harvesting dye molecules. “In other words,” says Dr. Andrea Paolella, the study’s lead author and researcher at Hydro-Québec, “our research team was able to simulate a charging process using light as a source of energy.”
In a major six-year trial involving over 20,000 women in 21 countries, researchers showed that tranexamic acid, a little-known blood-clotter invented in the 1950s, reduced maternal bleeding deaths by a third if it was given within three hours. It costs less than $2 a dose and does not require refrigeration.
In a recent experiment, Montagnon’s team took 30 plant varieties from 20 countries and placed them in a controlled environment in Laos, where they were subjected to temperatures as low as 2 degrees Celsius. The seven varieties that survived the cold snap will now be taken to other regions, from Brazil to Guatemala, to see if they can thrive in foreign soils and uncontrolled conditions. Eventually, the coffee plants deemed most resistant to both colder temperatures and leaf-rust will be selected for planting.
The Next Place To Invest (Tiffany D.)
As goods move more freely across the country, it might raise annual gross domestic product growth by as much as 1.7% a year, according to India’s National Council of Applied Economic Research.
What makes blue orchard bees enticing to farmers, aside from the fact that they’re inherently cool and native to this country, is that they’re actually much more efficient pollinators than honey bees. This is partly as a result of their solitary nature and partly a result of the fact that they they collect pollen with their abdomens, rather than their their legs, which is what honey bees do; BOBs perform this goofy sort of swimming motion within the flower to get pollen to stick to them. This swimming motion is really great for spreading pollen from one plant to another, if not quite as great for actually collecting pollen to give to their broods.
“The biggest threat to biodiversity is farming and development, not over-harvesting wild plants,” says Brinckmann.
In fact, a fifth of wild plant species today face extinction, and a third are threatened, because agriculture — more than any other factor — is consuming their habitat, according to the Kew Garden’s “State of the World’s Plants” report.
