A research team led by The Australian National University (ANU) has found a new way to help plants better survive drought by enhancing their natural ability to preserve water.
The findings have helped some plants survive 50 per cent longer in drought conditions, and could eventually benefit major crops such as barley, rice and wheat, which are crucial to world food supplies.
There is a good chance there are fresh vegetables in your refrigerator that will end up in the garbage instead of on your dinner plate.
Not that anyone goes to the grocery store with the intention of later throwing the food in the trash, but we all do it more often than we probably realize. Ruth Litchfield, a professor of food science and human nutrition at Iowa State University, says we waste about 20 pounds of food each month. And that is per person.
In the world of electronics, where the quest is always for smaller and faster units with infinite battery life, topological insulators (TI) have tantalizing potential.
In a paper published today in “Science Advances,” Jing Shi, a professor of physics and astronomy at the University of California, Riverside, and colleagues at Massachusetts Institute of Technology (MIT), and Arizona State University report they have created a TI film just 25 atoms thick that adheres to an insulating magnetic film, creating a “heterostructure.” This heterostructure makes TI surfaces magnetic at room temperatures and higher, to above 400 Kelvin or more than 720 degrees Fahrenheit.
In a study published Thursday, researchers evaluated the effects of sudden flooding from the Tohoku tsunami on more than 20 bird species nesting on the distant Pacific islands. The results shed light not only on how those birds weathered the dramatic rise in seas from the extreme event, but also how island wildlife may fare with the threat of rising sea levels and increased storm surges.
Many seabird species have disappeared from human populated higher islands, and their worldwide distributions are now concentrated on the low-lying islands protected as Wildlife Refuges and Marine National Monuments.
As farmers survey their fields this summer, several questions come to mind: How many plants germinated per acre? How does altering row spacing affect my yields? Does it make a difference if I plant my rows north to south or east to west? Now a computer model can answer these questions by comparing billions of virtual fields with different planting densities, row spacings, and orientations.
Something to Google today: mouse lemurs.
They weigh only about 50g and have big brown eyes. You may think you’re looking at a very cute rodent. You’re not.
