Each year, the red knot, a medium-sized shorebird, makes a 20,000-mile round-trip from the southern tip of Argentina to the Artic Circle – one of the longest migrations of any bird. And each year from April to June, the red knot stops over in the Delaware Bay to feed on horseshoe crab eggs resulting from the largest spawning of horseshoe crabs found on the East Coast of the United States.
Researchers from Virginia Tech and the New Jersey Division of Fish and Wildlife have documented a reduction in the number of red knot birds throughout the Delaware Bay tied to a decline in horseshoe crabs.
The research will be reported in The Journal of Wildlife Management, in the article, "Horseshoe Crab Eggs Determine Red Knot Distribution in Delaware Bay Habitats," by Virginia Tech fisheries and wildlife research scientist Sarah Karpanty, professor Jim Fraser, and associate professor Jim Berkson, New Jersey Division of Fish and Wildlife biologists Lawrence Niles and Amanda Dey, and Virginia Tech statistics professor Eric Smith. The article provides scientifically defensible information for wildlife management officials as well as for other members of the scientific community.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
