Unsustainable immune response to chronic viral infection is triggered by inflammation

Washington D. C. [USA], Oct. 22 : A study finds fundamental new mechanism explaining the inadequate immune defense against chronic viral infection. These results may open up new avenues for vaccine development.

In the course of an infection or upon vaccination, specialized cells of our immune system, so-called B cells, produce antibodies that bind viruses and inactivate them. In the context of chronic viral infections such as HIV or hepatitis C virus, however, antibody production by B cells is quantitatively inadequate and starts too late.

Here's how Alzheimer's disease can be possibly prevented

Washington D.C. [USA], Oct. 22 : A new study has found out that consuming pills that prevents the accumulation of toxic molecules in the brain might someday help prevent or delay Alzheimer's disease.

According to scientists at Baylor College of Medicine, Texas Children's Hospital and Johns Hopkins University School of Medicine, the study took a three-pronged approach to help subdue early events that occur in the brain long before symptoms of Alzheimer's disease are evident.

The scientists were able to prevent those early events and the subsequent development of brain pathology in experimental animal models in the lab.

Smartphones aren't as useful for helping teens maintain weight loss: Study

Washington D.C. [USA], Oct. 21 : In today's time, each and every teen use smartphone for every small thing, from learning new skills to communicating with friends to catching Pokemon.

But a new study at Brigham Young University finds smartphones are not as useful for helping teens maintain weight loss.

Running can improve swotting for exams

Washington D.C. [USA], Oct. 20 : If you feel you are forgetting all that you've crammed in during a study session, then go for a run.

A new study says that a student's choice of activity after a period of learning, such as cramming for an exam, has a direct effect on their ability to remember information.

The researchers behind the new study, from the University of Applied Sciences Upper Austria, say students should do moderate exercise, like running, rather than taking part in a passive activity such as playing computer games if they want to make sure they remember what they learned.

"I had kids in an age where computer games started to be of high interest," said lead author Harald Kindermann.

Here's how to keep your breast healthy

Washington D. C. [US], Oct. 15 : On the occasion of World Breast Health Day, Clovia brings to you, few tips to keep your breast healthy and nurtured.

Teenagers smoke to lose weight: Survey

Washington D. C. [US], Oct. 14 : Shunning popular beliefs that people smoke cigarettes because they're addicted to the nicotine, a recent study shows that among US teens who are frequent smokers, 46 percent of girls and
30 percent of boys smoke to control their weight.

And smoking to lose weight is significantly more common among teens, who feel they must slim down.

Girls who said they were "much too fat" were nearly 225 percent more likely to smoke to lose weight than girls who said their weight was about right.

For boys, being overweight was less of a predictor for smoking, perhaps because they feel less pressure from society to lose weight than girls do.

Food contamination can be checked by turning off lights

Washington D.C. [USA], Oct. 13 : Purdue University researchers have engineered a new detection method that would enable them to traces E. coli (bacteria) contamination in food by turning off the lights to see if the bacteria glow in the dark.

The bacteriophage called NanoLuc is a virus that only infects bacteria to produce an enzyme that causes E. coli O157:H7 to emit light if infected.

The process can shave off hours traditional testing methods, which can be critical when stopping the distribution of tainted foods.

Researcher Bruce Applegate said, "It's really practical. They (testing labs) don't have to modify anything they're doing. They just have to add the phage during the enrichment step of the testing protocol."

Enacting Shakespeare's play helps autistic kids in developing communication skills

Washoington D. C.[USA], Oct. 12 : A new study shows that recitation of Shakespeare's rhythmic language with physical gesture improves social and communication skills of children with autism spectrum disorder (ASD).

Children with ASD often have trouble understanding nonA-verbal behavior in social interactions and struggle to communicate.

Many avoid eye contact and miss visual cues, making it difficult to maintain peer relationships and share enjoyment of mutual interests.

Results showed better language skills and recognition of facial expressions in children with ASD.

Parenting can be more straining for mothers: Study

Washington D.C. [USA], Oct. 8 : A new study conducted at the Cornell University shows that while both the parents enjoy spending time with their children, managing them carries more strain for mothers.

This is is likely because moms spend more time with their kids while doing more onerous chores like basic childcare, cooking and cleaning, whereas dads spend more time with children in enjoyable, low-stress activities like play and leisure.

Mothers also do more solo parenting, experience more sleep disruptions and have less leisure time, which are all associated with lower levels of well-being.

The author of the study Kelly Musick said, "It's not that moms are so stressed out with their kids, but relative to fathers, they're experiencing more strain."

New bacteria detector could lead to prevention of food borne ailments

Washington D. C. [USA], Oct. 7 : In a recent research, scientists have developed a new nanosensor to detect the presence of pathogenicst rain of E. coli bacteria in food or water.

E. coli. is the common cause of contaminating the edible items and can lead to severe food borne diseases.

According to the Centres for Disease Control and Prevention, millions of illnesses and more than 1,000 deaths every year in the U. S. are attributed to food borne illness caused due to pathogens.

Conventional methods to screen food to find sickness-causing microbes can take as long as 24 hours, which is often too slow to efficiently catch tainted products before they hit store shelves.

Faster methods exist but have limitations.

Exposure to bright light can help men with low sexual drive: Study

Washington D. C. [USA], Sept. 20 : A recent research conducted at the University of Siena in Italy has found that the radiant glow of bright light may actually help some men combat their flagging sexual desire.

Researchers recruited 38 men suffering from clinically low libido to take part in a randomized, controlled experiment.

With the help of a specialized box, half the men were exposed to light that mimicked natural outdoor sunlight for a half-hour in the morning each day for 2 weeks, while the other half were exposed to much less intense light.

After two weeks, the men, who received genuine light therapy not only had higher amounts of testosterone in their blood, but they also reported a substantial increase in sexual desire and function compared to the placebo group.

Two things that'll make your `love-ship` last long

Washington D.C, Feb 24 : A relationship doesn't last because it was destined to, rather it lasts because two people made a choice to keep it and now, a new study has revealed how they do so.

The Chapman University study, which surveyed almost 40,000 married and/or co-habiting couples in 2006 to determine sexual satisfaction and happiness, found that couples who communicate well and have sex more frequently are more satisfied.

The Wall Street Journal reported that 83 percent of respondents recalled being sexually satisfied in the first six months, but this dropped down to around half for couples who were talking about their current sexual satisfaction.
