Magic twist angles of graphene sheets identified

Graphene is 200 times stronger than steel and can be as much as 6 times lighter. These characteristics alone make it a popular material in manufacturing. Researchers have now identified how twisted graphene sheets behave and their stability at different sizes and temperatures.

Bumblebees aversion to pumpkin pollen may help plants thrive

Researchers have found that squash and pumpkin pollen have physical, nutritional and chemical defense qualities that are harmful to bumblebees. The results of their recent study suggest that deterring bumblebees from collecting and eating pollen may provide an evolutionary benefit to cucurbit plants.

New minor planets found beyond Neptune

Using data from the Dark Energy Survey, researchers have found and cataloged more than 300 minor planets beyond Neptune, including more than 100 new discoveries. This updated catalog of trans-Neptunian objects, and the methods used to find them, could aid in future searches for undiscovered planets in the far reaches of the solar system.

Pollution: A possible end to 'forever' chemicals

Synthetic chemicals known as per- and polyfluoroalkyls, or PFAS, contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products since the 1940s has contaminated many water supplies across America. Engineers have now shown in modeling experiments that using excess electrons shatters the...

New method to grow human blood vessels

A team of researchers recently proved the ability to grow human-derived blood vessels in a pig -- a novel approach that has the potential for providing unlimited human vessels for transplant purposes.

Exoplanet where it rains iron discovered

Researchers have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporize metals. Strong winds carry iron vapor to the cooler night side where it condenses into iron droplets.
