Cells are crawling all over our bodies, but how?
For better and for worse, human health depends on a cell's motility –– the ability to crawl from place to place. In every human body, millions of cells –are crawling around doing mostly good deeds ––– though if any of those crawlers are cancerous, watch out.

The Genetic Structure of Anatolia: From the Neolithic to the Oghuz Migrations
Anatolia has witnessed many migrations and has been home to a variety of civilizations. The increasing availability of ancient DNA samples from different periods and cultures makes it now possible to examine the genetic changes that have taken place in Anatolia since the Neolithic. The ancient DNA revolution has already dispelled many myths, but myths and legends die hard. Some of the more persistent ones concern the impact of the last migration wave to hit Anatolia, marked by the arrival of...

Coral reefs in Palau surprisingly resistant to naturally acidified waters
Ocean researchers working on the coral reefs of Palau in 2011 and 2012 made two unexpected discoveries that could provide insight into corals' resistance and resilience to ocean acidification, and aid in the creation of a plan to protect them. The team collected water samples at nine points along a transect that stretched from the open ocean, across the barrier reef, into the lagoon and then into the bays and inlets around the Rock Islands of Palau, in the western Pacific Ocean. With each...

Magnetic nanoparticles could be key to effective immunotherapy
In recent years, researchers have hotly pursued immunotherapy, a promising form of treatment that relies on harnessing and training the body's own immune system to better fight cancer and infection. Now, results of a study led by Johns Hopkins investigators suggests that a device composed of a magnetic column paired with custom-made magnetic nanoparticles may hold a key to bringing immunotherapy into widespread and successful clinical use. A summary of the research, conducted in mouse and human...

Scientists reconstruct ancient impact that dwarfs dinosaur-extinction blast
Picture this: A massive asteroid almost as wide as Rhode Island and about three to five times larger than the rock thought to have wiped out the dinosaurs slams into Earth. The collision punches a crater into the planet's crust that's nearly 500 kilometers (about 300 miles) across: greater than the distance from Washington, D.C. to New York City, and up to two and a half times larger in diameter than the hole formed by the dinosaur-killing asteroid. Seismic waves bigger than any recorded...

New Science paper calculates magnitude of plastic waste going into the ocean
A plastic grocery bag cartwheels down the beach until a gust of wind spins it into the ocean. In 192 coastal countries, this scenario plays out over and over again as discarded beverage bottles, food wrappers, toys and other bits of plastic make their way from estuaries, seashores and uncontrolled landfills to settle in the world's seas. How much mismanaged plastic waste is making its way from land to ocean has been a decades-long guessing game. Now, the University of Georgia's Jenna Jambeck...

Scientists develop mesh that captures oil -- but lets water through
The unassuming piece of stainless steel mesh in a lab at The Ohio State University doesn't look like a very big deal, but it could make a big difference for future environmental cleanups. Water passes through the mesh but oil doesn't, thanks to a nearly invisible oil-repelling coating on its surface. In tests, researchers mixed water with oil and poured the mixture onto the mesh. The water filtered through the mesh to land in a beaker below. The oil collected on top of the mesh, and rolled...

Closing the case on an ancient archeological mystery
Climate change may be responsible for the abrupt collapse of civilization on the fringes of the Tibetan Plateau around 2000 B.C. WSU archaeologist Jade D'Alpoim Guedes and an international team of researchers found that cooling global temperatures at the end of the Holocene Climatic Optimum, a 4,000 year period of warm weather, would have made it impossible for ancient people on the Tibetan Plateau to cultivate millet, their primary food source. Guedes' team's research recently was published...

Bering Sea hotspot for corals and sponges
North of the Aleutian Islands, submarine canyons in the cold waters of the eastern Bering Sea contain a highly productive "green belt" that is home to deep-water corals as well as a plethora of fish and marine mammals. Situated along the continental slope, the area also supports a thriving -- but potentially environmentally damaging -- bottom-trawling fishing industry that uses large weighted nets dragged across the seafloor to scoop up everything in their path. A new study, conducted by...

Lab experiments question popular measure of ancient ocean temperatures
Understanding the planet's history is crucial if we are to predict its future. While some records are preserved in ice cores or tree rings, other records of the climate's ancient past are buried deep in the seafloor. An increasingly popular method to deduce historic sea surface temperatures uses sediment-entombed bodies of marine archaea, one of Earth's most ancient and resilient creatures, as a 150-million-year record of ocean temperatures. While other measures have gaps, this one is...

Rapid plankton growth in ocean seen as sign of carbon dioxide loading
A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found. What these findings mean remains to be seen, however, as does whether the rapid growth in the tiny plankton's population is good or bad news for the planet. Published Thursday in the journal Science, the study details a tenfold...

Male hormones help lemur females rule
Lemur girls behave more like the guys, thanks to a little testosterone, according to a new study. Males rule in most of the animal world. But when it comes to conventional gender roles, lemurs -- distant primate cousins of ours -- buck the trend. It's not uncommon for lady lemurs to bite their mates, snatch a piece of fruit from their hands, whack them in the head or shove them out of prime sleeping spots. Females mark their territories with distinctive scents just as often as the males do....

Tiny genetic tweak unlocked corn kernels during domestication
If not for a single genetic mutation, each kernel on a juicy corn cob would be trapped inside a inedible casing as tough as a walnut shell. The mutation switches one amino acid for another at a specific position in a protein regulating formation of these shells in modern corn's wild ancestor, according to a study published in the July 2015 issue of GENETICS, a publication of the Genetics Society of America. "Humans completely reshaped the ancestor of corn, effectively turning the cob inside...

Eukaryotes: A new timetable of evolution
Contaminated samples have evidently created some confusion in the timetable of life. On the basis of ultra-clean analyses, an international team, including scientists from the Max Planck Institute for Biogeochemistry, has disproved supposed evidence that eukaryotes originated 2.5 to 2.8 billion years ago. In contrast to prokaryotes such as bacteria, eukaryotes have a nucleus. Some researchers thought they had discovered molecular remnants of living organisms in rock samples up to 2.8 billion...

First imagery from echolocation reveals new signals for hunting bats
The ability of some bats to spot motionless prey in the dark has baffled experts until now. By creating the first visual images from echolocation, researchers reveal we have been missing how bats sense their world. Publishing in the journal eLife, scientists from Queen Mary University of London (QMUL) and the University of Bristol suggest that instead of searching for prey directly, bats intimately learn the layout of a home range - down to the surface of individual leaves and stones. When one...

'Fourth strand' of European ancestry originated with hunter-gatherers isolated by Ice Age
The first sequencing of ancient genomes extracted from human remains that date back to the Late Upper Palaeolithic period over 13,000 years ago has revealed a previously unknown "fourth strand" of ancient European ancestry. This new lineage stems from populations of hunter-gatherers that split from western hunter-gatherers shortly after the 'out of Africa' expansion some 45,000 years ago and went on to settle in the Caucasus region, where southern Russia meets Georgia today. Here these...
