Sweat sensors may bring medical diagnostics to wearables

sweat

Sweat contains a trove of medical information.

Sweat leaves unsightly blotches on our clothes, drips down our faces, and makes us stink. It cools us when we overheat, but most of the time we think of it purely as an inconvenience. But, soon we may learn to like our sweat a lot more, or at least what it can reveal about our health.

melting image 21312

July was REALLY hot in a lot of places.

With July just behind us the National Weather Service confirms what you probably already knew: It was really seriously totally sweatily hot over the majority of the United States. In fact there were 2,676 tied or broken heat records across the nation, doubling last year’s stats. All told about 60 people died from the heat last month…

New Bee Species Discovered in Canada

Sweat bee

Researchers Jason Gibbs who was working on a study of sweat bees discovered a new species while commuting from downtown Toronto to York University. It is one of 19 new species he found while examining 84 species of sweat bees in Canada — so named because they are attracted to perspiration — which are common in North America. His study goes a long way in cataloging a variety of bee that has proven a “nightmare” to study.

Women Can Sense Attraction in a Man’s Sweat

The smell of a man’s sweat differs according to what mood he is in and women can pick up on changes that indicate attraction, according to new research.
The study, led by Dr Denise Chen, assistant professor of psychology at Rice University, in Texas, America, involved introducing two types of male sweat to 19 women in their 20s – one type was labelled ‘normal’, the other ‘sexual’.
The sweat was gathered from a selection of men who had polyester pads attached to their armpits.
The ‘normal’ sweat was gathered during a 20-minute session in which the men were asked to watch educational videos.
They were then asked to watch 20 minutes of an erotic video, during which the ‘sexual’ sweat was gathered.
The female participants were exposed to these different scents while researchers monitored their brain activity.
The women did not realise it but their brains not only recognised the scents but responded to them.
Dr Chen said the ‘sexual’ sweat lit up different regions of the participants’ brains.
She added her results suggested the female brain is capable of recognising the smell of a man who is attracted to her.
Dr Chen and her colleagues now intend to expand their research by look at how these scents actually affect a man and woman’s behaviour towards each other.

Women More Prone to Wrinkling than Men

Women more prone to wrinkling than men
A new study has confirmed that women wrinkle more easily than men.
The researchers have attributed women’s wrinkles woes to fewer sweat and sebaceous glands, fewer blood vessels, and a different muscle structure.
According to CBS News medical correspondent Dr. Jennifer Ashton, women are more likely to get wrinkles around the mouth and nose.
While talking on the CBS News ’ ‘The Early Show’, Ashton said as women age the muscles pull in closer to the mouth, and cause wrinkles.
She recommended women to avoid direct exposure to sun and quit smoking. She also insists to avoid going under the knife and evade drastic weight loss.
The study appears in Aesthetic Surgery Journal .
But there’s new hop for wrinkles.
Forget splashing thousands on anti-wrinkle creams or botox injections, for a group of researchers have developed a pillow that can iron out the ugly looking lines.
Boffins have developed a copper oxide pillow case, with tests showing those who used it for four weeks had fewer lines and wrinkles than those using conventional bedding. Clinical trials, supervised by a dermatologist, were carried out on 57 volunteers for four weeks, with the volunteers either given an anti-wrinkle pillow, which feels no different from normal fabric or a similar conventional pillow.
By the end of the trial, those sleeping on the copper pillows were statistically more likely to have lesser wrinkles. Jeffrey Gabbay, the owner of the Cupron company which used its expertise in making copper medical dressings to develop the pillow case, said, “The surgeon doing our wound-healing trial remarked how an increase in collagen was helping to heal wounds.”
“We wondered if it might work on fixing wrinkles and lines on the face. So we had some copper woven pillows made up and noticed that over a few days of lying on a cooper pillow lines on the face started to soften,” Telegraph quoted him, as saying. “It has been the most fantastic discover. The fabric has an impact on all lines but is best at ironing out the finer lines,” he added.
The researchers believe moisture from the skin releases copper ions from the pillow cases, which stimulate the production of collagen below the surface of the skin.

Scientists have developed a technique for retrieving fingerprints from fired bullets

A scientist has fabricated a new technique to ‘see’ fingerprints erased from fired bullets.  Alex Goddard of University of Leicester has developed a technique that involves studying the chemical and physical interactions occurring between the metal and the fingerprint sweat deposit — which have been overlooked until now.

Smell Of Fear Is Real

Being terrified is infectious

The smell of fear really does exist, according to a new study, which also suggests that being terrified is infectious.  The study, conducted by Dr Bettina Pause and colleagues at the University of Dusseldorf in Germany, suggests that people subconsciously detect whether others are scared by picking up chemicals they release from their bodies.

The Ab Solo – Helps Chisel Out Those Six-Pack Abs

The Ab Solo - Helps Chisel Out Those Six-Pack Abs 

Exercising regularly in a specific pattern can only get monotonous and hence most of us lose interest over a period of time. It is thus always advisable to include a few changes from time to time in order to make the workout regime more interesting. This not only helps in rebuilding motivation but also challenges the body to gear up and shed the flab. In my personal experience of sweating it out at a local gym for years, I have realized that losing weight isn’t as tough as getting six-pack abs. That’s where the Ab Solo can step in, to help you chisel out an spectacular abdomen. This latest abdomen and core training gear seems to be the hottest addition in the arena of fitness training. Joe and Chris Arsenault’s idea has shaped up well to make way for an exceptional abdominal, cardio, as well as core muscle workout without the help of any human assistance.

The Return of the Alpha Male

The Return of the Alpha Male

Make room! The tough guys are back

The female body has always managed to evoke emotions – from wonder to awe, to envy, desire, and even disgust. It makes you wonder: when was the last you salivated over a male body?

We mean, really salivated over a real man? A man you’d love to romance and love from the depths of your soul. Solid, dependable and drool worthy. None of that plastic virility and porn star physiques or androgynous bodies so characteristic of the nineties and the ramps.

Sweat Ducts May Act As Antenna For Lie Detection

 Sweat Ducts May Act As Antenna For Lie Detection

Politicians now have a new reason to worry – a technology that can determine if they are lying… from a distance.

Our skin may contain millions of tiny “antennas” in the form of microscopic sweat ducts, say researchers in Israel. In experiments, they found evidence that signals produced by bouncing electromagnetic waves off the tiny tubes might reveal a person’s physical and emotional state from a distance.
