Journal Club: Landscape connectivity key to future animal migration needs in the United States

As the climate changes, plants and animals worldwide are migrating to follow their preferred conditions. Human activity, however, can impede these movements. Now researchers are mapping out ways to help species escape to more suitable climes. The scientists detailed their … Continue reading

Journal Club: Human genetics contributes to gut microbiome composition

Microbial communities in the human gut are formed at birth and shaped over time by a person’s diet, and other aspects of lifestyle and environment. Now scientists have confirmed that human genetic sequence polymorphisms also play a key role in … Continue reading

Journal Club: Charred fossilized eggs suggest that humans contributed to Australia’s megafaunal extinction

A huge flightless bird known as Genyornis newtoni once roamed the Australian Outback along with a host of other giant animals. Now scientists have unearthed what may be the first reliable evidence that humans contributed to the extinction of these … Continue reading

In vitro engineering of muscle tissue

Engineered skeletal muscle — the muscle under a person’s voluntary control — could help treat muscle disease and injury. However, previous in vitro attempts to engineer skeletal muscle with all the properties of actual muscle have failed. Now scientists have … Continue reading

Disk-shaped nanoparticles more easily absorbed than rods

Nanoparticles — particles only nanometers or billionths of a meter wide — are widely investigated as vehicles to help deliver drugs into patients. Now scientists find the shape of these nanoparticles influences how well they enter cells, with disk-shaped nanoparticles … Continue reading

Gut microbiota help Western corn rootworms adapt

Insects are masters of innovation and so, perhaps, are their gut microbiota. Researchers examining Western corn rootworms have discovered the insects’ gut microbes are helping it adapt to crop rotation, a common pest control method. Corn and soy are the dominant … Continue reading

Mystery of pulsating corals solved

[youtube http://www.youtube.com/watch?v=Bp5ZTdmuScU] The way pulsating corals open and close their soft, feathery tentacles in a rhythmic grabbing motion is what earned them their name. First described nearly 200 years ago by Jean-Baptiste Lamarck—the naturalist most noted today for his ideas … Continue reading
