Manipulating brain activity can boost confidence

Manipulating brain activity can boost confidence

Scientists have found a way to manipulate people's brain activity to boost self-confidence as this method maybe used in the future to induce other positive states and behaviours.

The study was published in the journal of Nature Communications.

Self-confidence is an essential quality to succeed in the world, such as in business environments, politics or many other aspects of our everyday life.

Recent advances in neuroscience have highlighted the plasticity of the brain, indicating it is malleable even later in life.

Despite prevalent usage, LEDs reduce profitability for manufacturers

Despite prevalent usage, LEDs reduce profitability for manufacturers

A recent survey conducted by the National Academies of Sciences, Engineering, and Medicine reports that despite residential and commercial industries widely adopting energy-efficient light emitting diodes (LEDs), the drop in LED prices is driving away manufacturers because of decreased profitability, dramatically dislocating and restructuring the solid-state lighting marketplace.

Researchers discover planet-eating star, similar to Sun

Researchers discover planet-eating star, similar to Sun

In a recent research, a team of scientists from the University of Chicago has made the rare discovery of a planetary system with a host star similar to Earth's sun.

Published in the Astronomy and Astrophysics journal, what's most intriguing about the research is the star's unusual composition, which indicates it ingested some of its planets.

"It doesn't mean that the sun will 'eat' the Earth any time soon. But our discovery provides an indication that violent histories may be common for planetary systems, including our own," said Jacob Bean, co-author of the study.

NASA finds rainfall data on Tropical Cyclone Vardah

NASA finds rainfall data on Tropical Cyclone Vardah

NASA gathered rainfall data on Tropical Cyclone Vardah from its birth in the Bay of Bengal through its movement west into the Arabian Sea.

Rainfall totals were estimated over Vardah's lifetime and path, and NASA found heavy rainfall from the remnants on Dec. 14.

Although Vardah's circulation dissipated the remnants were still producing rainfall in a few stormy areas when the Global Precipitation Measurement mission or GPM core observatory satellite flew over the Arabian Sea on Dec. 13 at 9:31 p.m. EST (Dec. 14 at 0231 UTC).

Groundwater resources around the world could be depleted by 2050s

Groundwater resources around the world could be depleted by 2050s

Human consumption could deplete groundwater in parts of India, southern Europe and the U.S. in the coming decades, according to new research presented at the 2016 AGU Fall Meeting.

New modeling of the world's groundwater levels finds aquifers -- the soil or porous rocks that hold groundwater -- in the Upper Ganges Basin area of India, southern Spain and Italy could be depleted between 2040 and 2060.

In the U.S., aquifers in California's Central Valley, Tulare Basin and southern San Joaquin Valley, could be depleted within the 2030s.

When in trouble, horses ask humans for help

When in trouble, horses ask humans for help

A Japanese researcher team has found when horses face problems that they cannot solve, they use visual and tactile signals -- touching and pushing -- to get human attention and ask for help.

The findings, published in journal of Animal Cognition, suggest that horses alter their communicative behavior based on humans' knowledge of the situation.

Teens' smartphones addiction can make them obese

Teens' smartphones addiction can make them obese

A recent study reveals teenagers spending more than five hours on digital devices like tablets, smartphones and television are 43 percent more likely to become obese compared with adolescents who do not spend time on these devices.

The study, published in the Journal of Pediatrics, found that children who reported spending more time on screen devices and watching television engaged in behaviors that can lead to obesity.

Beware! Teenage obesity ups heart disease risk in 20s

Beware! Teenage obesity ups heart disease risk in 20s

Obesity in your adolescence is linked to increased risk of developing heart disease in early adulthood, regardless of ethnicity, warns a new study.

The study was published in British Medical Journal Open.

"Previous studies that tracked growth from childhood, are mainly of White Europeans, with few varying in ethnicity," said lead author Seeromanie Harding from King's College London.

Your saliva test can check body's immunity

Your saliva test can check body's immunity

Researchers from the University of Birmingham have found that antibody levels in saliva are linked to those in blood serum, suggesting a new method for assessment of protection against bacterial infections.

The study was published in the journal Biomarkers.

They found that in general, higher antibody concentrations in serum were associated with higher concentrations in saliva, with the strongest relationships observed for IgA antibodies.

Teen girls' delusion about weight, body image linked to alcohol use

Teen girls' delusion about weight, body image linked to alcohol use

Teenage girls worrying about their figure and are trying to lose, maintain or gain their weight without any medical need are more likely to have had at least one drink in their life or have engaged in episodes of heavy drinking than girls of the same age without body image misperceptions, warns a new study.

The study has been published in journal of Studies on Alcohol and Drugs.
