Study finds GPA more important than standardized tests

A study released in early February de-emphasized the role of standardized test scores in relation to graduation rates and college GPAs, calling into question the mandated submission of these tests when applying to some colleges. ...

Nanoparticle networks' design enhanced by theory

For close to two decades, Cornell scientists have developed processes for using polymers to self-assemble inorganic nanoparticles into porous structures that could revolutionize electronics, energy and more.

New research reveals role of methionine in enzyme catalysis

The first convincing evidence that the amino acid methionine plays a role in catalysis in an enzyme has been uncovered by researchers from the University of Bristol. Previously, it was thought that methionine was only involved ...

New material could help with carbon storage

New research led by University of Nebraska-Lincoln chemist Xiao Cheng Zeng has led to the discovery of a new material that could have significant implications for a variety of challenges, from carbon dioxide storage to planetary ...

Cooking up new nanoribbons to make better white LEDs

As the world moves away from incandescent light bulbs, light-emitting diodes (LEDs) are growing in popularity. They use significantly less energy and have far longer lifetimes than do the traditional incandescent bulbs, which ...

Climate change to affect Antarctic predator-prey relationships

The Ross Sea, a major, biologically productive Antarctic ecosystem, "clearly will be extensively modified by future climate change" in the coming decades as rising temperatures and changing wind patterns create longer periods ...

Tiny tool measures heat at the nanoscale

How heat flows at the nanoscale can be very different than at larger scales. Understanding how surfaces affect the transport of the fundamental units of heat, called phonons, could impact everything from thermoelectric materials ...
