Doc versus machine
Increasingly powerful computers using ever-more sophisticated programs are challenging human supremacy in areas as diverse as playing chess and making emotionally compelling music. But can digital diagnosticians match, or even outperform, human physicians? The answer, according to a new study, is “not quite.”

For women, caffeine could be ally in warding off dementia
Among a group of older women, self-reported caffeine consumption of more than 261 mg per day was associated with a 36 percent reduction in the risk of incident dementia over 10 years of follow-up. This level is equivalent to two to three 8-oz cups of coffee per day, five to six 8-oz cups of black tea, or seven to eight 12-ounce cans of cola.

Why do more men than women commit suicide?
Why do more men die when they attempt suicide than women? The answer could lie in four traits, finds scientists. There are over 6,000 British lives lost to suicide each year, and nearly 75 per cent of those are male. However, research has found women are more likely to suffer from depression, and to attempt to take their own life.

The new findings heart repair research
Scientists trying to find ways to regenerate a damaged heart have shed more light on the molecular mechanisms that could one day make this a reality. Whilst other organs such as the liver can regenerate, the heart muscle has very little ability to do so after suffering damage, such as a heart attack.
In the womb the body is able to produce heart muscle cells but soon after birth it effectively stops producing them.

Entitlement — a damning recipe for happiness
Entitlement–a personality trait driven by exaggerated feelings of deservingness and superiority–may lead to chronic disappointment, unmet expectations and a habitual, self-reinforcing cycle of behavior with dire psychological and social costs, according to new research. In a new theoretical model, researchers have mapped how entitled personality traits may lead to a perpetual loop of distress.

With nearly sixty percent of American adults now taking prescription medications–from antidepressants to cholesterol treatments–there is growing concern about how many drugs are flowing through wastewater treatment facilities and into rivers and lakes. Research confirms that pharmaceutical pollution can cause damage to fish and other ecological problems–and may pose risks to human health too.

We all know that we can quickly lose cardiovascular endurance if we stop exercising for a few weeks, but what impact does the cessation of exercise have on our brains? New research examined cerebral blood flow in healthy, physically fit older adults (ages 50-80 years) before and after a 10-day period during which they stopped all exercise.

How long do you want to live? Your expectations for old age matter
Why do some people want to live a very long time, while others would prefer to die relatively young? In a latest study, a team of researchers investigated how long young and middle-aged adults in the United States say they want to live in relation to a number of personal characteristics. The results showed that more than one out of six people would prefer to die younger than age 80, before reaching average life expectancy.

Intestinal flora effects drug response
Intestinal flora has multiple influences on human health, but researchers have revealed that it is also likely to have an effect on the body’s response to drugs. Recent research suggests that changes in the intestinal flora, caused by antibacterial and antibiotic drugs or individual differences between people, may have an effect on a person’s response to drugs including side effects. The research focused on the changes in proteins due to the condition of intestinal flora that affect the response to drugs in the liver and kidneys.

Is depression in parents, grandparents linked to grandchildren’s depression?
If you read my blog often, it’s no surprise I suffer from PTSD, depression, and anxiety issues. Maybe it’s from my military service, but maybe it’s my father’s, or his father’s, maybe it’s an insidious family legacy that was just never noticed. This is because having both parents and grandparents with major depressive disorder (MDD) was associated with higher risk of MDD for grandchildren, which could help identify those who may benefit from early intervention.

Microcephaly discoveries in non-Zika cases explain abnormal brain growth
Long before Zika virus made it a household word, the birth defect called microcephaly puzzled scientists and doctors — even as it changed the lives of the babies born with it during the pre-Zika era. But new discoveries reported by an international team of scientists may help explain what happens in the developing brains of babies still in the womb, causing them to be born with small brains and heads.

A doctor’s guidance may reassure us more than we realize -especially if she says she is likely to recommend treatment in her field of expertise, known as “specialty bias.” Doing research in a real-world healthcare setting, researchers have found that when surgeons revealed their bias toward their own specialty, their patients were more likely to perceive them as trustworthy. And patients are more apt to follow their recommendation to have surgical treatment.

The team of researchers used a strain of Zika currently impacting the Americas, and found that the virus infects about 20 percent of cells on average, evades immune system detection, and continues to replicate for weeks.

Antibody therapy opens door to potential new treatment for HIV
The development of antiretroviral therapy, a combination of drugs that slows the replication of HIV in the body, has transformed the treatment of this infection. What was once a certain death sentence is now a chronic condition that people can live with for decades. But this therapy has drawbacks. There are side effects, including kidney problems, decreased bone density, and gastrointestinal problems. And if a person discontinues his or her treatment, even missing a few doses, the level of the virus in the body is able to rebound quickly.

Without the discovery of antibiotics we could not — and most certainly would not — be living in the world we do today. It was a discovery that would save countless lives, while simultaneously compromising our future. From the use (and unfortunate misuse) of antibiotics, we gave rise to more virulent bacteria that have become resistant to more and more types of antibiotics.

Some bacterial CRISPRs can snip RNA, too
You’ve probably seen news stories about the highly lauded, much-discussed genome editing system CRISPR/Cas9. But did you know the system was actually derived from bacteria, which use it to fight off foreign invaders such as viruses? It allows many bacteria to snip and store segments of DNA from an invading virus, which they can then use to “remember” and destroy DNA from similar invaders if they are encountered again. Recent work from a team of researchers including Carnegie’s Devaki Bhaya demonstrates that some bacteria also use the CRISPR/Cas system to snip and recognize segments of RNA, not just DNA.

A new insight into how sharks regenerate their teeth, which may pave the way for the development of therapies to help humans with tooth loss, has been discovered by scientists. The study has identified a network of genes that enables sharks to develop and regenerate their teeth throughout their lifetime. The genes also allow sharks to replace rows of their teeth using a conveyer belt-like system.
