Maybe some day, depression and anxiety could benefit from good vibrations.

University of Arizona researchers have found in a recent study that ultrasound waves applied to specific areas of the brain appear able to alter patients' moods. The discovery has led the scientists to conduct further investigations with the hope that this technique could one day be used to treat conditions such as depression and anxiety.

Women are waiting longer before getting married - if they get married at all, according to a new analysis.

The U.S. marriage rate is now at 31.1 - which in statistical terms means roughly a rate of 31 marriages per 1,000 married women, not 31 percent. That rate is 60 percent lower than 1970. In 1920 the marriage rate was 92.3. The wave of gay marriage legislation across the US will likely cause a temporary blip in that, at least until expensive gay divorces kick in, but the overall trend will remain downward.

A research project at Kansas State University has potential to treat human deafness and loss of balance.

More than 28 million people in the United States suffer some form of hearing loss and mutation of the SLC26A4 gene, normally found in the cochlea and vestibular organs of the inner ear as well as in the endolymphatic sac, a non-sensory part of the inner ear, is implicated as one of the most common forms of hereditary hearing loss in children worldwide.

When the mutant mice lack SLC26A4 expression, their inner ears swell during embryonic development. This leads to failure of the cochlea and the vestibular organs, resulting in deafness and loss of balance.

A new biomaterial that facilitates generating bone tissue - artificial bones, in their words - from umbilical cord stem cells has gotten a patent for researchers in Granada, Spain.

The material is an activated carbon cloth support for cells that differentiate, giving rise to a product that can promote bone growth. They received a patent though the method has not yet been applied using in vivo models but it could help manufacture medicines for the repair of bone or osteochondrial, tumour or traumatic lesions and to replace lost cartilage in limbs.

Now that they have obtained artificial bones in the laboratory, they are going to implant this biomaterial in experimental animal models to see if it can regenerate bone in them.

Our digestive system is home to trillions of bacteria which battle for our health. Sometimes they help us digest food and something they battle harmful microbes.

When we take antibiotics to combat bacterial infections, beneficial bacteria can also be killed off, leaving us at risk of infection by harmful bacteria. Clostridium difficile is one of those harmful bacteria and is the leading cause of hospital infections in England and Wales and in hospitals all over the developed world.

As C. difficile becomes more resistant to antibiotics, it becomes harder to treat, so new ways of controlling C. difficile infections are needed.

Bring on the bacteriophages.

A study using adults who listened to short Hungarian phrases and then sang them back found that singing in a foreign language can significantly improve learning how to speak it.  

Three randomly assigned groups of twenty adults took part in a series of five tests as part of a study conducted by researchers at the University of Edinburgh's Reid School of Music. The singing group performed the best in four of the five tests. 

In one test, participants who learned through singing performed twice as well as participants who learned by speaking the phrases. Those who learned by singing were also able to recall the Hungarian phrases with greater accuracy in the longer term.

Do looks matter in the work place? There are a lot more unattractive people running departments and entire companies than there are pretty ones - but a new paper by academics says just the opposite. Pretty people have an easier time on the job.

The paper by Timothy Judge, professor of management at the University of Notre Dame, and Brent Scott from Michigan State University, is the first to link attractiveness to cruelty in the workplace.
