Rare insect discovery reveals a new species from the dinosaur age

Some 99 million years ago, during the age of the dinosaurs, a tiny insect belonging to a species previously unknown to science became trapped in tree resin. The resin hardened and turned into amber, and the fossil preserved within it has now enabled a team of researchers from the

Standard 3D printers let labs build and adapt tools for bacterial research

Studying microorganisms requires instruments with extremely high precision. Such instruments are expensive and take a long time to manufacture using traditional methods, which has slowed progress in the field. It has also been difficult for the biologists who use these instrument

Unmowed strips attract insects, but many abandon partially mowed dikes

Municipalities are increasingly mowing dikes and verges in stages, so that insects can make longer use of the plants growing there. Mowing is essential to keep a dike strong, explains ecologist Constant Swinkels of Radboud University. "If you don't mow, trees or sturdy shrubs suc

A novel path to fusion ignition: Heat first, then add fuel

For more than 70 years, fusion energy researchers have used a particular equation to judge whether a plasma would stay hot and dense enough—for long enough—to reach a point where it could sustain itself without any more external power added. While that equation marks the finish l

Vagus Nerve Stimulation Could Help New Skills Stick

Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, revealing a potentially important window when the brain is still locking in a new skill. The effect was linked to rhythmic changes in brain blood vessels, hinting that body-to-brain

Cancer-fighting t cells burn out. Scientists may have found a fix

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn thro

New forensic evidence supports Egyptian "retainer sacrifice"

Egyptologists have long debated whether the earliest pharaohs of the First Dynasty were buried with various servants and officials to serve them in the afterlife—a form of human sacrifice . But there is very little archaeological evidence available, given that many of the earlies
