Desert locusts' jaws sharpen themselves, materials scientist discovers

Sharks lose teeth all their lives, replacing them in a kind of endless rotating Rolodex, while humans, of course, get only our two sets. Beavers' teeth, notoriously, grow all their lives and have to be worn down to prevent ...

The origin of the sun's magnetic field could lie close to its surface

The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun's field is ...

Seeking stronger steel, systematic look at 120 combinations of alloy elements provides clues

Decarbonization of automobiles not only requires a shift from gasoline engines to electric motors, but also quality steel parts that help the motors run while lessening the weight of vehicles. High-performance steel materials ...

Fossilized circles in the sand on South Africa's coast may be artwork by our early ancestors

If you have walked on a dune surface after windy conditions have settled, you may have been privileged to recognize one of Nature's wonders: scratch circles. These are structures formed when the end of a tethered object is ...

Hungry, hungry white dwarfs: Solving the puzzle of stellar metal pollution

Dead stars known as white dwarfs, have a mass like the sun while being similar in size to Earth. They are common in our galaxy, as 97% of stars will eventually become white dwarfs. As stars reach the end of their lives, their ...

Study calls for a repurposing of input subsidies to promote sustainable IPM practices

A CABI-led study has revealed that participation in the Zambia Farmer Input Subsidy Program (FISP)—particularly the flexible e-voucher system—encourages synthetic pesticide use at the expense of sustainable practices.
