LONDON: Are you experiencing fragmented sleep? If yes, then it’s high time that you consult a doctor, for a study says it affects the ability to build memories and could raise the risk of developing dementia in later life. “Sleep continuity is one of the main factors affected in various pathological conditions that impact memory including Alzheimer’s disease and other age-related cognitive deficits,” said Dr Luis de Lecea, who led a team at Stanford University which carried out the study.

(Reuters Life!) – Men are more concerned with their partner’s body type than women but they also seem to value family more highly, according to a new survey released on Tuesday. Nearly half of men questioned in the poll of 70,000 people said they would ditch a partner who gained weight, compared to only 20 percent of women. Two-third of men also said they had fantasized about their partner’s friends, while only one-third of women had done so. “Even as men are getting more comfortable with meeting their girlfriends online and less anxious about who she’s ‘friending’...

(Reuters Health) – Swedish teenagers who consumed more folic acid got better school grades, a small study published in the journal Pediatrics has found. But don’t run out and stock up on the B vitamin with the rest of your school supplies just yet, one expert warns. “There is very little deficiency of folic acid in North America,” Deborah O’Connor, a nutrition researcher who was not involved in the study, told Reuters Health. “If you’re already sufficient, there is not a lot of evidence that taking more supplements will help.” Read more…

A strain of gonorrhea is that is resistant to all currently available antibiotics has been identified by researchers in Japan. Gonorrhea is a bacterial infection that can be transmitted through oral, genital or anal sex with an infected person. If left untreated, the disease can cause other problems, including sterility and a greater susceptibility to HIV. The newly identified strain of the sexually transmitted infection, called H041, is resistant to the last remaining drugs that treat gonorrhea, known as cephalosporin-class antibiotics, researchers told the International Society for Sexually Transmitted...

MADRID, Spain — Doctors in Spain have carried out the world’s first double leg transplant, giving new lower limbs to a patient who lost both legs at mid-thigh in an accident, officials said Monday. The Valencia regional government said the surgical team was led by Dr. Pedro Cavadas, who in 2009 carried out Spain’s first face transplant — the first anywhere to include a new tongue and jaw. The government statement said the operation at La Fe Hospital in Valencia was extremely complex and Cavadas will wait at least 48 hours to release more information. “Today we can say...

Probing colons has never been this much fun. Japanese researchers have developed the world’s first self-propelled endoscopy device, a remote controlled tadpole-like camera that can “swim” through the digestive tack gathering imagery along the way. This kind of endoscopy isn’t wholly new, of course, but previous iterations of ingestible cameras relied on natural muscle contractions to move them through the body. The “Mermaid,” as it is known, simplifies the process by moving quickly through the digestive tract to its destination, whatever that point may be. Read more…

Saliva Science Crime scene investigators could soon use saliva left behind at crime scenes to determine the ages of those involved at the scene Thinking of pulling off the perfect crime? Here’s one more thing you now need to take into account (thanks for nothing, science): your saliva. Yes, it’s no longer enough to keep track of every single hair, every last skin cell, and and absolutely everything you touch at the scene of your nefarious scheme. Researchers at UCLA have figured out how to determine age to within five years from nothing more than a saliva sample. The method relies on a process...

Health officials in the Indian state of Rajasthan are launching a new campaign to try reduce the high population growth in the area. They are encouraging men and women to volunteer for sterilisation, and in return are offering a car and other prizes for those who come forward.

It is expected to overtake that of China by 2030. Sitaram Sharma, the head doctor of Jhunjunu in western India, is hopeful that the chance to win a...

Researchers may have struck a solution to reverse the signs of Type 2 diabetes, the most common form of diabetes, according to a recent experiment. Individuals living with Type 2 diabetes have issues regulating the amount of blood sugar in their bloodstreams that would otherwise be picked up and stored within the body’s cells as energy. Insulin helps escort sugar into cells, but for people living with diabetes, the body doesn’t respond appropriately to insulin and needs more of it to regulate sugar in the bloodstream. The findings were drawn from a group of 11 participants (nine men...

Duct tape – is there no end to its usefulness? Apparently not. Now we learn that using duct tape in hospitals could be a tool in the fight against infectious disease. Call it a handyman’s quarantine. An infection-prevention team at Trinity Medical Center in the Quad Cities along the Illinois and Iowa border, wanted to create safe zones in which healthcare workers could talk to patients with infectious diseases. So they used 3-foot squares of red duct tape to indicate where precisely that zone was located. As explained in a news release from the Assn. for Professional in Infection Control and...
