The person you’re talking to is lying to you if he/she copies your body language closely and nods along in agreement. This is the conclusion of a new study carried out by a combined team of researchers from Aarhus University in Denmark and Arizona State University, USA. So if you suspect someone is lying about something, it would be wise to keep an eye on the person throughout the conversation.
The human brain is visibly divided into two sections – left and right, with each performing different set of operations. The structure has inspired one of the most widely accepted ideas about the brain: that the left section controls logic and the right section controls creativity.
Depression can lead to permanent changes in the structure of the brain. In a study conducted at the University of Edinburgh, researchers found alterations in parts of the brain known as white matter – the key component of the brain and spinal cord consisting mainly of nerve fibres. White matter is critical for normal functioning of the brain, and its disruption has been linked to problems with emotion processing and thinking skills.
Researchers at the Universities of York, Munich and Cardiff have discovered that all quantum particles exhibit a unique property known as ‘backflow,’ which gives them the ability to move in the opposite direction to the way in which they are being pushed.
If there’s nothing around to block our view, 5 kilometres (3.1 miles) is the furthest we can see. Atmospheric moisture, dust or smoke can reduce our visibility, but for the most part, everything we can see happens within an area of just 80 square kilometres. The higher up we go, the further we will be able to see. So how much of the Earth can we actually see at once?
Researchers have unveiled a formula that explains why some animals run, fly and swim faster than all others. Knowing just the animal’s weight and the medium it moves in—water, air or across land, the formula can calculate maximum speed of the animal with 90 percent accuracy.
By 2050, the UN estimates that as many as 3.2 million people will live to 100 compared to 316,000 in 2011. Also, a 2013 study from the University of Massachusetts found that 25 year olds today can look forward to "2.4 more years of a healthy life" while a 65-year-old today can expect to live 1.7 extra years - than people who lived 20 years ago.
Owl wings are designed in such a way that they generate a lot of lift with very little flapping. Now, scientists from Chiba University in Japan and Shanghai Jiao Tong University in China have revealed how inspiration from owls’ wings could help make quieter wind turbines, aircraft, and drones.
Fentanyl is a synthetic opioid which is 100 times stronger than morphine and 50 times stronger than heroin. Simply touching it can cause a person to overdose. Fentanyl inhibits pain signals in multiple pathways along the brain and spinal cord, and it also causes your brain to make extra dopamine creating sensations of intense euphoria and relaxation.
