High strength cannabis linked to increased risk of becoming dependent: Study

Washington D.C. [USA], Oct. 22 : A new study adds to accumulating evidence that high-potency cannabis in associated with an increased risk of users becoming dependent on cannabis.

Estimates suggest around 182 million people worldwide use cannabis each year, a number that could rise as legalisation of recreational use and/or medical use increases. Roughly nine percent of people who try cannabis will become dependent on it at some point in their lifetime. People who are dependent on cannabis are often unable to cut down or quit, despite experiencing persistent negative effects from the drug.

Children repair errors in their speech while talking to themselves

Washington D.C. [USA], Oct. 21 When it comes to private speech, one of the major differences between adults and preschoolers is that adults typically talk to themselves in their heads, while preschoolers talk to themselves aloud, particularly while playing or working on a task.

Private speech is a good thing for a child's cognitive development; however, it may be important that children monitor and repair errors in their speech, even when talking to themselves.

Rank in social order is linked with being healthy or not

Washington D.C. [USA], Oct. 21 : A new study says that uncertainty about one's social rank may lead to health deterioration.

In the study by University of California - Davis, center researchers showed that having an uncertain position in the rhesus social hierarchy may be harmful to the health of those at the top of the hierarchy but not necessarily for those at the bottom.

Monkeys don't have friend-lists or Instagram followers. Their social rank is not governed by computer algorithms, but by many complex factors according to lead authors of the study researchers Jessica Vandeleest and Brianne Beisner.

Still, the monkey model established by the UC Davis researchers could one day help doctors learn more about the way that social hierarchy affects the health of humans.

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

Washington D.C. [USA], Oct. 21 : In today's time, every teen uses 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.

In a 24-week behavioural study that combined traditional weight control intervention with smartphone-assisted helps, researchers found that teens lost weight initially, but could not maintain it when smartphones were the only tool helping them stay on track.

Alcohol abuse is linked to increased risk of schizophrenia in later life

Washington D.C. [USA], Oct. 21 : A new study shows that alcohol, cannabis and other illicit drugs can greatly increase the risk of developing schizophrenia in later life.

Previous research has analysed potential links between substance abuse and schizophrenia. However, due to methodological limitations in the existing literature (including lack of adjustment for co-abuse), uncertainties remain.

In this new study, the authors analysed nationwide Danish registers to establish a cohort of 31,33,968 individuals, identifying 2,04,505 cases of substance abuse and 21,305 diagnosed with schizophrenia. Information on substance abuse was taken from various registers and did not include psychotic symptoms caused by substance abuse in the definition.

TB tricks one's immune system to spread it among others

Washington D.C. [USA], Oct. 21 : A new study suggests that tuberculosis (TB) tricks the immune system into attacking the body's lung tissue so that the bacteria are allowed to spread to other people.

The concept, as per the University of Southampton research, proposes that current ideas about how tuberculosis develops in patients may be incomplete and that, in fact, infection causes autoimmunity, where the immune system reacts incorrectly to its own tissue.

Tuberculosis kills more people than any other infectious disease, and the causative bacterium, Mycobacterium tuberculosis, is becoming increasingly resistant to antibiotics used to treat the infection.

High-stress jobs may lead to early death: Study

Washington D.C. [US], Oct. 17 : A recent research found that those in high-stress jobs with little control over their workflow die younger or are less healthy than those who have more flexibility and discretion in their jobs and are able to set their own goals.

Using a longitudinal sample of 2,363 people in their 60's over a seven-year period, the researchers found that for individuals in low-control jobs, high job demands are associated with a 15.4 percent increase in the likelihood of death as compared to low job demands.

For those in high-control jobs, high job demands are associated with a 34 percent decrease in the likelihood of death compared to low job demands.

Assisted reproduction may cut down birth defects for middle-aged women

Washington D.C. [US], Oct. 17 : Babies born to women in the age of 40 and over from assisted reproduction have fewer birth defects compared with those from women, who conceive naturally at the same age, suggests a new research.

This is contrary to the widespread belief that greater risk of birth defects after assisted conception is due to the frequent use of these services by older women.

The researchers believe this could point to the presence of more favorable biological conditions in IVF (in vitro fertilization) specific to pregnancies in older women but they're currently working to determine the exact cause.

The research is based on the data of all live births recorded in South Australia from 1986-2002.

Foster care children are at greater risk of mental, physical health problems

Washington D.C. [US], Oct. 17 : The children, who are brought up under foster care system, are at a significantly higher risk of mental and physical health problems - ranging from learning disabilities, developmental delays and depression to behavioral issues, asthma and obesity, suggests a recent research.

Co-author of the study, Kristin Turney, said: "No previous research has considered how the mental and physical well-being of children who have spent time in foster care compares to that of children in the general population."

Consumption of soy protein in early life may prevent bone loss in adulthood

Washington D.C. [US], Oct. 15 : A new research has found that early dietary nutrition heavy in soy protein isolate can protect against serious bone loss during adulthood.

This also is the first time that scientists have used an animal model to show concrete evidence of a protective effect of an early-life soy protein isolate diet on adult bone loss.

Leas researcher Jin Ran said, "Appropriate early-life nutrition can optimize peak bone mass. Consumption of soy foods has a variety of health benefits, including amelioration of bone loss during adulthood."

To make their discovery, the team used a very young female rat model.

Want customer satisfaction? Hire a creative staff: Study

Washington D.C. [US], Oct. 15 : Organizations in the service sector that have more creative employees enjoy higher levels of customer satisfaction, suggests a new research led by the University of East Anglia (UEA).

The study looked at how creativity-orientated HR practices influence customer satisfaction. The authors recommend that businesses should invest in developing the creative capabilities of their customer service employees by implementing a system of HR practices tailored towards creativity.

These could include workshops to help staff increase their creative confidence and training to provide creative thinking and problem solving techniques.

Scientists discover coenzyme with potentials to postpone aging

Washington D.C. [US], Oct. 15 : New research conducted at the Center for Healthy Aging and the American National Institute of Health found that coenzyme NAD+ plays a main role in aging processes.

The researchers when injected the coenzyme in mice and roundworm, it not only postponed the onset of aging but also extended life.

The researchers found that this new knowledge will eventually be able to help patients with Alzheimer's and Parkinson's disease.

As we live longer and longer, a lot of people are occupied with their state of health and not least, quality of life in old age.

Therefore, researchers all over the world are trying to understand aging mechanisms, as this knowledge may eventually help to postpone physical aging and extend life.

New detection method paves way for early prevention of psychosis

Washington D.C [US], Oct. 15 : Scientists have developed a new probability model that has shown 70 percent accuracy in predicting patients, who are at greatest risk of having their first psychotic episode within 12 months, compared with the 28 percent accuracy of the current criteria.

The new model combines medical history, the latest bedside clinical assessment and biomarkers of fatty acids to determine a patient's risk of psychosis.

In this preliminary study, the researchers used data from 40 European patients.

Preventing child obesity in the next generation must start before conception

New Delhi [India], Oct. 14 : The key to preventing obesity in future generations is to make their parents healthier before they conceive, suggests a recent research.

In a series of papers, the researchers said that the time before couples conceive represents a missed opportunity to prevent the transmission of obesity risk from one generation to the next.

They argue that a new approach is needed to motivate future parents to live a healthier lifestyle.

There is now a wealth of evidence that the risk of obesity and its associated conditions, such as heart disease diabetes and some cancers, could impact the developing baby.

In turn, when the child becomes a young adult they may pass the risk of obesity on to their children - it is a vicious cycle.

Study explains association between marriage attitudes and sexual behaviours

Washington D.C. [USA], Oct. 14 : A recent research conducted at the University of Missouri has found that attitudes and desires about marriage can place young people on trajectories toward or away from healthy sexua behaviours .

The first of its kind study examined links between marriage attitudes and sexual behaviours across racial and ethnic minority groups as well as the role skin tone plays in shaping marriage attitudes.

Lead researcher Antoinette Landor, said : "Understanding the impact of marriage and cohabitation attitudes on decisions about sex is important because this work may help scholars and professionals better understand how such beliefs impact behaviours. Further, examining what early factors influence risky sex can lead to better prevention."

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 non­verbal 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.

Study identifies everyday factors that may trigger dementia risk

Washington D.C [USA], Oct. 12 : In a recent study, experts have created a shortlist of environmental factors that may possibly contribute to our risk of developing dementia.

The list includes exposure to air pollution and a lack of vitamin D but the evidence is not yet sufficient to draw solid conclusions.

Dementia is known to be associated with lifestyle factors such as high blood pressure in mid-life, smoking, diabetes, obesity, depression and low educational attainment, as well as genetic factors.

These risk factors however, leave around a third of dementia risk unexplained.

Researchers sought to determine whether other issues are at play, including the environment.

Report suggests neglected cancer is killing many youth

Washington D.C.[India], Oct. 11 : A recent report shows thatfunding for research into brain tumors is still woefully inadequate, despite it being the biggest cancer killer of children and people under the age of 40.

The brain tumor research team at Plymouth University focuses on identifying and understanding the mechanism that makes a cell become cancerous and exploring ways in which to halt or reverse that mechanism.

They test new drugs in human primary cell cultures and investigate how existing drugs could be re-purposed as a therapy for brain tumours, making drug therapies available to patients safely and more quickly.

This is vital work, as the only treatments currently available for brain tumors are invasive surgery or radiotherapy.

Warm childhood environment can lead to better relationship quality 60 years later

Washington D.C. [USA], Oct. 11 : Growing up in a warm family environment in childhood is associated with feeling more secure in romantic relationships in the age of 80s, suggests a recent research carried out at Harvard Medical School.

The findings show that men who grew up in caring homes were more adept at managing stressful emotions when assessed as middle-aged adults, that helps to explain why they had more secure marriages late in life.

Lead researcher Robert Waldinger said, "Our study shows that the influences of childhood experiences can be demonstrated even when people reach their 80s, predicting how happy and secure they are in their marriages as octogenarians,"

Animal study paves way for treatment of Alzheimer's with gene therapy

Washington D.C. [USA], Oct. 11 : In a recent research, scientists have prevented the development of Alzheimer's disease in mice by using a virus to deliver a specific gene into the brain, hence, opening avenues for potential new treatments of the disease.

Previous studies by the same team suggest, this gene called PGC1 - alpha, may prevent the formation of a protein called Amyloid-beta peptide in cells.

Amyloid-beta peptide is the main component of Amyloid plaques, the sticky clumps of protein found in the brains of people with Alzheimer's disease.

These plaques are thought to trigger the death of brain cells.

Alzheimer's disease affects around 520,000 people in the UK. Symptoms include memory loss, confusion, and change in mood or personality.
