German was once the language of engineering and science, but as the world became more scientific, English became the common tongue. The reason may be German's notoriously irregular nouns.

The term sexting has been used to describe incidents where people take nude or semi-nude photos or videos of themselves and exchange that content via text or private social media messages.

To adults it is recognized as somewhat ridiculous but at least there is the pretense of mature consent, that it is only being shared with trusted romantic partners, while with teens there is concern these images will find their way into the hands of others and follow them throughout their early lives at a time when everything is already dramatic.

As the Apollo 11 Lunar Module approached the moon's surface for the first manned landing, commander Neil Armstrong switched off the auto-targeting feature of the LM's computer and flew the spacecraft manually.

A new video, created at Arizona State University's School of Earth and Space Exploration, shows what Armstrong saw out his window as the lander descended — and that means we can see for yourself why he took control. They used the crew's voice recording, the timings, a video taken on film and images taken from lunar orbit by the LROC over the last 10 years.

Optogenetics biotechnology, using light to manipulate neurons so that they can be turned on or off, has led to a device that replicates the way the brain stores and loses information.

The new chip is based on an ultra-thin material that changes electrical resistance in response to different wavelengths of light, enabling it to mimic the way that neurons work to store and delete information in the brain.

New efforts by the FDA and coastal cities to kill off e-cigarettes with bans and restrictions will drive existing users to smoke more cigarettes, according to new research from Duke Health.

The findings, from a survey of 240 young U.S. adults who use both e-cigarettes and traditional tobacco cigarettes, are scheduled to be published July 15 in the journal Substance Use & Misuse.

The online survey asked participants aged 18 to 29 to predict their use of two products they already used -- e-cigarettes and traditional tobacco cigarettes -- in response to hypothetical regulations to limit e-cigarette flavors, limit the customizability of e-cigarettes or eliminate the nicotine in e-cigarettes.

An antibody is an agent of the immune system that attaches to an antigen. Usually antibodies recognize antigens on a virus or bacteria and attach to the invader to mark it for destruction by other immune cells.

In a new study,  University of Colorado Anschutz researchers engineered an antibody to recognize and attach to a protein called EGFR. Bladder tumors (but not healthy cells) are often covered in EGFR. Other researchers have hooked molecules of chemotherapy to antibodies that recognize EGFR and have used this antibody-antigen system to micro-target the delivery of chemotherapy. In this case, researchers used nifty chemistry to attach gold nanoparticles to antibodies.
