Even though air travel is safer than ever and in many cases cheaper than 10 or 20 years ago, travelers love to complain about its agonies. Cramped and narrow seats, crying babies, chatty seat mates and armrest wars are common gripes. But other factors contribute much more to feelings of distress, especially on longer flights.
Treatment for certain diabetes cases involves constant monitoring of blood-glucose levels and daily insulin shots. But scientists are now developing a painless “smart” patch that monitors blood glucose and releases insulin when levels climb too high.
Today, a stroke usually leads to permanent disability – but in the future, the stroke-injured brain could be reparable by replacing dead cells with new, healthy neurons, using transplantation. Researchers have taken a step in that direction by showing that some neurons transplanted into the brains of stroke-injured rats were incorporated and responded correctly when the rat’s muzzle and paws were touched.
When a material is made, you typically cannot change whether that material is hard or soft. But a group of University of Michigan researchers have developed a new way to design a “metamaterial” that allows the material to switch between being hard and soft without damaging or altering the material itself.
Life’s genetic code has only ever contained four natural bases. These bases pair up to form two “base pairs”—the rungs of the DNA ladder—and they have simply been rearranged to create bacteria and butterflies, penguins and people. Four bases make up all life as we know it.
Researchers at the Huntsman Cancer Institute say a protein discovered in elephants appears to attack and destroy cancer cells found in humans.

Sometimes the most clever ideas are the simplest. Here is a great example. Surgical masks do not offer adequate protection against viruses. This has been a problem forever, and now it may be solved. By using a little salt.
Scientists have developed a molecule that reverses antibiotic resistance in multiple strains of bacteria at once, making it one of the most promising advances we’ve had to date in the fight against superbugs.
For the first time, scientists have found that non-invasive brain stimulation can be used like a scalpel to affect a specific improvement in precise memory. Precise memory, rather than general memory, is critical for knowing the building you are looking for has a specific color, shape and location, rather than simply knowing the part of town it’s in.
Learning Morse code, with its tappity-tap rhythms of dots and dashes, could take far less effort—and attention—than one might think. The trick is a wearable computer that engages the sensory powers of touch, according to a recent pilot study.
Getting drunk could make it harder to enter your password – even if your brainwaves are your login.
Brainwave authentication is one of many biometric measures touted as an alternative to passwords. The idea is for a person to authenticate their identity with electroencephalogram (EEG) readings.
An illusion that mimics near-death experiences seems to reduce people’s fear of dying.
Mel Slater at the University of Barcelona, Spain, and his team have used virtual reality headsets to create the illusion of being separate from your own body
Last year, a Korean geneticist produced for Russian police forces a pack of cloned Belgian Malinois which were reportedly cloned from the best sniffer dogs Korea had to offer.
Scientists have successfully proven that sex cells can be created by reprogramming any kind of cell, leading to a number of new collection possibilities in the field of fertility.
This new possibility involves some common ethical concerns, but it also introduces some new concerns. Scientists are tackling these issues head-on even in these earliest stages of development, and policy changes are imminent.
A baby has been born to a previously infertile couple in Ukraine using a new type of “three-person IVF”.
Doctors in Kiev used a method called pronuclear transfer in what is a world first.
The concept is essentially the same as using a conventional lens made of glass or plastic. By altering the shape of the lens, light can be focused to a point, or scattered outward and diffused. The LDAL is a theoretical next step, and uses lasers to create artificial lenses out of gases in the atmosphere
In the future, we’re all going to be Spiderman. At least, those of us who can afford super-sticky light-controlled wall-climbing spider boots.
A team of German scientists created a strong adhesive that can quickly stick and unstick with just a flash of light.
