A new paper in the Journal of Environmental Analytical Chemistry states next generation 'heated' tobacco devices - confusing to the public because heating nicotine vapor is the mechanism behind e-cigarette devices - produce side-stream emissions similar to secondhand cigarette smoke.

Stanford engineers have created a plastic "skin" that can detect how hard it is being pressed and generate an electric signal to deliver this sensory input directly to a living brain cell.

Zhenan Bao, a professor of chemical engineering at Stanford, has spent a decade trying to develop a material that mimics skin's ability to flex and heal, while also serving as the sensor net that sends touch, temperature and pain signals to the brain. Ultimately she wants to create a flexible electronic fabric embedded with sensors that could cover a prosthetic limb and replicate some of skin's sensory functions.

Computers have scanned aerial photographs and conducted the first automated mass-crowd count in the world, thanks to the work of researchers at the University of Central Florida.

Counting large-scale crowds has been a long, tedious process involving people examining aerial photographs one at a time - and it has been termed accurate, with organizers often claiming results 1000% greater than police and journalists. They are able to make claims and stick to them because the traditional method involves dividing photographs into sections and counting the number of heads per inch. 

Human twin embryos created in the laboratory by splitting single embryos into two using a common method known as blastomere biopsy may be unsuitable both for IVF and for research purposes, according to a new study.

In the UK, the Human Fertilisation and Embryology Authority Code of Practice says that clinics should not be producing embryos for IVF treatment by embryo splitting, such genetically identical embryos should be used only for research purposes. However, in the US the Ethics Committee of the American Society for Reproductive Medicine has not indicated any major ethical objections to placing two or more artificially created embryos with the same genome into the uterus. 

An international team have used cutting edge genomic methods to uncover key biological insights that help explain the protective effects of the world's most advanced malaria vaccine candidate, RTS,S/AS01 (RTS,S). 

RTS,S is the first malaria vaccine candidate to complete phase 3 trials. Originally designed by scientists at GlaxoSmithKline (GSK) in 1987, development of the vaccine is now being advanced by a public-private partnership between GSK and PATH Malaria Vaccine Initiative.

Applying highly sensitive sequencing technology to more patient samples than previously tested, the team was able to determine that genetic variation in the protein targeted by RTS,S influences the vaccine's ability to ward off malaria in young children. 

A new crime scene identification technique for fingerprint detection and analysis adds a drop of liquid containing crystals to surfaces, which means investigators using a UV light are able to see invisible fingerprints "glow" in about 30 seconds.

The strong luminescent effect creates greater contrast between the latent print and surface enabling higher resolution images to be taken for easier and more precise analyses.

In 1939, a Russian engineer proposed a "flying submarine" -- a vehicle that can seamlessly transition from air to water and back again. While it may sound like something out of a James Bond film, engineers have been trying to design functional aerial-aquatic vehicles for decades with little success. Now, engineers may be one step closer to the elusive flying submarine.

The biggest challenge is conflicting design requirements: aerial vehicles require large airfoils like wings or sails to generate lift while underwater vehicles need to minimize surface area to reduce drag.

Researchers have developed a new lightweight and stretchable material with the consistency of memory foam that has potential for use in prosthetic body parts, artificial organs and soft robotics. The foam is unique because it can be formed and has connected pores that allow fluids to be pumped through it.

The polymer foam starts as a liquid that can be poured into a mold to create shapes, and because of the pathways for fluids, when air or liquid is pumped through it, the material moves and can change its length by 300 percent.

While applications for use inside the body require federal approval and testing, Cornell researchers are close to making prosthetic body parts with the so-called "elastomer foam."

X smoked a pack of cigarettes a day, used alcohol like a fish uses water, and lived to a ripe old age. His brother Y did the same thing and succumbed to cancer at age 55. Why do some individuals develop certain diseases or disorders while others do not?

A new approach uses artificial intelligence to illuminate cellular processes and suggest possible targets to correct aberrations.  What is interesting is they used artificial intelligence to do it.

Miss Georgia tripped in the final round of the 2015 Miss America Pageant and actress Jennifer Lawrence stumbled on her way to accept an Academy Award.

It has happened to all of us. And it happens to robots as well.

Researchers at Georgia Tech have identified a way to teach robots how to fall with grace and without serious damage. The work is important as costly robots become more common in manufacturing alongside humans. The skill becomes especially important, too, as robots are sought for health care or domestic tasks - working near the elderly, injured, children or pets.
