Migrating Arctic Geese Are Confused, Exhausted By Rising Temperatures

By Merrit Kennedy
Barnacle geese have sped up their migration to their breeding grounds because of warming Arctic temperatures.

Warmer weather means that barnacle geese fly faster to their breeding grounds, leaving them too tired to lay eggs right away. By the time they're ready, the babies have missed the best food.

Physicists Go Small: Let's Put A Particle Accelerator On A Chip

By Joe Palca
An early prototype of the silicon-chip-sized particle accelerator that physicists at Stanford are working on. Eventually, miniature accelerators might have a role in radiating tumors, the scientists say.

A tiny accelerator could be useful in medicine as well as basic science. Instead of speeding up beams of electrons through giant tunnels, the aim here is to build accelerators on semiconductor chips.

Scientists Hunt For A Test To Diagnose Chronic Brain Injury In Living People

By Tom Goldman
UCLA researchers are using a radioactive tracer, which binds to abnormal proteins in the brain, to see if it is possible to diagnose chronic traumatic encephalopathy in living patients. Warmer colors in these PET scans indicate higher concentrations of the tracer.

Doctors are closer to a test in live brains that could help diagnose chronic traumatic encephalopathy, a disease that's been linked to concussions and other repeated brain assaults.

Researchers Study Thousands Of Ticks Collected By The People They Bit

By Erin Blakemore
Time outdoors leaves you vulnerable to tick bites and the diseases they can transmit. New research seeks to a better picture of the geographic spread of ticks that carry dangerous pathogens.

Researchers invited the public to help them study the geographic spread of ticks that carry pathogens that can sicken humans. People were eager to oblige by sending in the pesky bugs that bit them.

To Repel Ticks, Try Spraying Your Clothes With A Pesticide That Mimics Mums

By Allison Aubrey
When ticks come into contact with clothing sprayed with permethrin, research shows, they quickly become incapacitated and are unable to bite.

Just in time for summer hikes and outdoor play, a study finds that the ticks that often convey Lyme disease become unable to bite, and soon die, after exposure to clothing treated with permethrin.

Scientists Hope Lab-Grown Embryos Can Save Rhino Species From Extinction

By Nell Greenfieldboyce
Keeper Zachariah Mutai attends in March to Fatu, one of only two female northern white rhinos left in the world, in the pen where she is kept for observation, at the Ol Pejeta Conservancy in Laikipia county in Kenya. Scientists have successfully grown hybrid white rhino embryos in the lab, stoking hopes that a purebred northern white rhino could be implanted in a surrogate.

Only two northern white rhinos remain, and they're both female. But researchers said Wednesday that they successfully have created embryos using sperm collected from the males before they died out.

Microbial Magic Could Help Slash Your Dinner's Carbon Footprint

By Hannah Thomasy
Endophytes are microbes that live inside plants — the ones tagged with a fluorescent dye in this image are found in poplars. The microbes gather nitrogen from the air, turning it into a form plants can use, a process called nitrogen fixation. Researchers are looking at how these microbes could be used to help crops like rice and corn make their own fertilizer.

In one year, fertilizer production in the U.S. emitted as much carbon dioxide as two million cars. What if we could help plants make their own nitrogen so they wouldn't need man-made chemicals?

Researchers find that during extra innings, baseball umpires make calls in a way that tends to end games sooner. This seems to be because umpires aren't given additional money to work extra innings.
