Hair of the dog? Lots of water? Cup of coffee? The quest for an effective hangover cure has never really led to a Holy Grail fix-it-all solution. What if you could counteract the impact of alcohol in your system before you ever even got to the hangover stage? Newly published research shows one potential path to the creation of a "sober pill."

We're a long way off from popping down to the local drug store and grabbing a bottle of B-Sober-Now pills, but the use of nanocapsules to reduce the blood alcohol content in mice might be the first step in that direction.… Read more

A man who lost his hand in an accident is due to receive the first bionic hand designed to more fully simulate the sensation of feeling.

Scheduled for later this year, the surgery will connect the bionic hand directly to the man's nervous system. The goal is for him to not only move the hand but also receive touch signals from the sensors across the hand, according to a story published Sunday by The Independent.

Specifically, the hand would be attached through electrodes connected to the median and ulnar nerves, two of the main nerves in the human arm, … Read more

It's no secret that the standard hand-eye coordination tests doctors use to monitor neuromuscular deficits -- typically when a patient is injured or as a patient ages -- can be subjective, relying on, say, descriptions of reflexes and cognitive status such as "mild," "moderate," and "severe."

So researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard, the Beth Israel Medical Center, and Hebrew SeniorLife have been developing what they call a rapid neuroassessment device, nicknamed NeuroAssess, to measure neuromuscular performance quantitatively instead of qualitatively.

They've recently tested it on 150 … Read more

The sky is totally falling.

As if it weren't enough that a meteor boomed across the Russian sky today, shattering windows and injuring about 1,000 people, an asteroid 150 feet across is about to sideswipe our planet.

Asteroid 2012 DA14, while unrelated to the meteor, is just as scary. It will graze us at just 17,200 miles from the surface, passing between Earth and our geosynchronous weather and communications satellites.

Possible asteroid strikes are no joke, and if you ask me (or the dinosaurs), they represent the biggest threat to our planet aside from human stupidity.

Fortunately, some non-stupid humans are finally getting serious about countering this threat. … Read more

Where's Don King when you need him?

It seems that everybody and their mother-in-law are buzzing about the tussle between a New York Times car reviewer and Tesla Motors. It's a good example of the kind of public dialog that can happen in the age of the Internet and instrumented devices, such as a super-fast car that is basically a computer on wheels.

To briefly catch you up, a fierce debate broke out not long after New York Times writer John Broder wrote a review reporting shortcomings in the range of Tesla's Model S electric car during … Read more

For most of us, light-sensitive cells that line our retinas convert light rays into electrical impulses that travel through the optic nerve to the brain to be assembled into images. But for an estimated 1 in 4,000 people in the U.S. with a genetic condition called retinitis pigmentosa, or RP, those cells are damaged, which most commonly impairs vision at night. What's more, treatment to prevent eventual (if unlikely) total blindness remains elusive.

Enter the Argus II Retinal Prosthesis System, which the FDA approved today to treat a very specific population: adults 25 and older with severe to profound RP who have bare or no light perception in both eyes but inner layer retinal function and a history of the ability to see forms.

Though the bionic eye doesn't restore vision to these patients, it could allow them to detect light and dark, which in turn could help them identify the movement or location of objects.… Read more

New research out of UC Davis suggests that when couples who are romantically involved interact, their heart and respiratory rates sync up.

But that doesn't mean you should bring a pair of heart rate monitors to scout out potential partners on your first date. When study participants were paired with someone outside their relationship, neither their heart rates nor their breathing closely matched.

To conduct their research, which was funded by the National Science Foundation and published in the International Journal of Psychophysiology and Emotion, the psychologists in one study placed couples a few feet apart in a quiet, calm room and instructed them not to talk or touch. In another, the couples were asked to mimic each other without speaking. In both instances, heart and respiratory rates were closely matched.… Read more

If you like someone just a teeny-weeny bit, this Cupid is your ticket to love on Valentine's Day.

Physics students at Brigham Young University crafted this nifty god from carbon nanotubes that are 10,000 times smaller than a human hair.

They began by laying down microscopic iron "seeds" to form a Cupid pattern. When they applied a heated gas to the iron, the seeds sprouted into the desired shape. … Read more

One of my favorite things about watching old movies is hearing how people might have spoken in eras past -- the expressions they used, their old-school smack talk. But what did the languages from thousands of years back sound like? Hollywood, as far as I know, has yet to make a movie in which characters talk in authentic proto-Austronesian.

The language nerd in me, was, therefore, excited to discover that scientists from UC Berkeley and the University of British Columbia have created a computer program to rapidly reconstruct vocabularies of ancient languages using only their modern language descendants. … Read more
