A new study has shown that caterpillars that masquerade as twigs are actually using clever behavioural strategies to outwit their predators. ANI

Autistic brains 'focus more on visual skills'
People with autism concentrate more brain resources in the areas associated with visual detection and identification, and conversely, have less activity in the areas used to plan and control thoughts and actions, according to a new study. ANI

New polymer-based solar-thermal device cuts heating cost by 40pc
Researchers have developed a new polymer-based solar-thermal device that could shave the cost of heating a home by as much as 40 percent. ANI

Researchers have found a way of mimicking the body's natural mechanism of fighting inflammation. ANI

Why hypertensive people's BP increases during exercise
Scientists at UT Southwestern Medical Center have found one reason people with hypertension experience an even greater increase in their blood pressure when they exercise, and they've learned how to prevent the rise. ANI

Study provides new insight into Parkinson's disease
A new study has provided the first link between the most common genetic risk factor for Parkinson's and the hallmark accumulation of a protein called alpha-synuclein within the brains of people with Parkinson's. ANI

Horticultural interventions could bring kids closer to nature
Researchers in Finland think that horticultural interventions can bring children closer to nature. ANI

Potential driver of some aggressive prostate cancers found
A research team, including an Indian-origin scientist, has found that the mutations of a gene called KRAS, which is known to play a role in numerous cancers, may drive the aggressive spread of a rare subset of prostate cancers. ANI

Scientists find new way to 'starve' cancer cells
Scientists have developed a new treatment for cancer which rather than attacking tumours directly, prevents the growth of new blood vessels in tumours, starving them of oxygen and nutrients, thereby preventing their growth. ANI

Physical activity may prevent stress on telomeres
Psychological stress leads to shorter telomeres - the protective caps on the ends of chromosomes that are a measure of cell age and, thus, health. But UCSF scientists say that exercise can prevent this damage. ANI

How natural disasters, political unrest affect Internet usage
A study on natural disasters and political unrest has provided unique insight into the effects they have on the Internet. ANI

Gene that can influence a person's risk for developing epilepsy identified
Scientists at Vanderbilt University have discovered a new gene that can influence a person's risk for developing epilepsy. ANI

Binge-drinking teens risk lasting brain changes
Underage binge drinking can create lasting brain changes that could affect teens' lives as adults, according to new research. ANI

Spring moulds found in Spain may aid search for water on Mars
A new study on the origin and evolution of peculiar morphologies caused by ancient subterranean springs in the central pre-Pyrenees of Catalonia (Spain) may aid the search for water on Mars. ANI

Measuring oxidative stress may help predict atrial fibrillation risk
Researchers from Emory University School of Medicine have found that measuring oxidative stress could help doctors predict the risk of developing atrial fibrillation, the most common heart beat irregularity. ANI

Low income linked to mental disorders, suicide attempts
A new report has revealed that low levels of household income are associated with several lifetime mental disorders and suicide attempts, and a decrease in income is associated with a higher risk for anxiety, substance use, and mood disorders. ANI

Jobless men 'at greater risk of dying prematurely'
A new research has revealed that unemployment increases the risk of premature mortality by 63 per cent. ANI

Novel way to identify heart disease earlier during sleep found
New research from the University of Gothenburg, Sweden, has revealed that a specially customised pulse oximeter attached to the finger can be used to detect changes in heart and vessel function while you sleep, and also identify patients at increased risk of cardiovascular disease. ANI

Study associates herpes to Alzheimer's disease
A new technique to observe herpes simplex virus type 1 (HSV1) infections growing inside cells has been developed by laboratories at the University of New Mexico (UNM), Brown University, and House Ear Institute (HEI). ANI

Neural activity linked to food addiction identified
A new study has found that people with an addictive-like eating behaviour have greater neural activity in certain regions of the brain similar to substance dependence, including elevated activation in reward circuitry in response to food cues. ANI

Scientists have identified specific bone marrow cells that can transform into skin cells to repair damaged skin tissue. ANI

Social isolation, stress-induced obesity 'ups breast cancer risk'
Researchers at Georgetown Lombardi Comprehensive Cancer Center have found that stress from social isolation, combined with a high-fat diet, increases levels of a brain neurotransmitter - neuropeptide Y, or NPY - in mice that then promotes obesity, insulin resistance, and breast cancer risk. ANI
