Is this why time speeds up as we age?

Recent memories run in our brains like sped-up old movies. In childhood, we capture images in our memory much more quickly. The complexities of grownup neural pathways are no match for the direct routes of young brains. None Mechanical engineer Adrian Bejan of Duke University has an interesting theory regarding the strange phenomenon by which time seems to speed up as we age. It's not the only theory, mind you, but an interesting one. In his just-published paper, "Why the Days Seem Shorter as...

Better detection of concussions using vital signs

As a father of a young ice hockey player, I’m all too familiar with every parent’s concern about concussions. As a neuroscientist, I chose not to accept that it was okay to rely on subjective and error-prone tests to understand how best to care for our brains after concussion. We dared ourselves to think bigger, and to devise a solution that was larger than concussions – to ask the question: “Why don’t we have objective vital signs for brain function?”We have vital signs for our body like heart ...

New evidence for a human magnetic sense that lets your brain detect the Earth’s magnetic field

Do human beings have a magnetic sense? Biologists know other animals do. They think it helps creatures including bees, turtles and birds navigate through the world.Scientists have tried to investigate whether humans belong on the list of magnetically sensitive organisms. For decades, there's been a back-and-forth between positive reports and failures to demonstrate the trait in people, with seemingly endless controversy.The mixed results in people may be due to the fact that virtually all past s...

Why is 18 the age of adulthood if the brain can take 30 years to mature?

Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s. None At what age does someone become an adult? ...

Mini-brains attach to spinal cord and twitch muscles

Researchers find a new and inexpensive way to keep organoids growing for a year. Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells. The mini-brains took control of muscles connected to the spinal cords. None Scientists have been experimenting with organoids — mini-brains — for a while now, but research just published in Nature Neuroscience takes things up another notch. Three things distinguish the lentil-sized mini-brains developed by Madeline Lancaster...

A new study has investigated who watched the ISIS beheading videos, why, and what effect it had on them

In the summer of 2014, two videos were released that shocked the world. They showed the beheadings, by ISIS, of two American journalists – first, James Foley and then Steven Sotloff. Though the videos were widely discussed on TV, print and online news, most outlets did not show the full footage. However, it was not difficult to find links to the videos online. At the time, Sarah Redmond at the University of California, Irvine and her colleagues were already a year into a longitudinal study to as...

Your romantic partner is probably less intelligent than you think, suggests new study

It's now well known that many of us over-estimate our own brainpower. In one study, more than 90 per cent of US college professors famously claimed to be better than average at teaching, for instance – which would be highly unlikely. Our egos blind us to our own flaws.But do we have an even more inflated view of our nearest and dearest? It seems we do – that's the conclusion of a new paper published in Intelligence journal, which has shown that we consistently view our romantic partners as being...

Actors show altered brain activity when in character, study finds

Method actors employ an intensive approach to acting that involves staying in character for long periods of time.The recent study asked trained method actors a variety of hypothetical questions under four different scenarios.The results showed changes in brain activity depending on whether actors were in and out of character, including alterations to activity in the prefontal cortex — a key region in terms of self-awareness.

How Emotional Freedom Technique Can Transform Your Mental Health for Good

A fast-paced life surely offers you the luxuries you have always dreamed of. On the flip side, however, it’s uglier than you have ever expected. The constant rat race and the urge to stay ahead in every sphere of life have resulted in tremendous peer pressure, relationship issues, social image concerns, and different types of disorders. One out of every five individual suffers from anxiety, anger issues, and depression owing to pressure at work and stringent societal norms. Do you know what is m...

Brazilian scientists produce mini-brains with eyes

Mini-brains, or "neural organoids," are at the cutting edge of medical research. This is the first one that's started developing eyes. Stem cells are key to the growing of organoids of various body parts. None Organoids are tiny, self-organized tissue cultures. They're comprised of stem cells that can be programmed to replicate naturally occurring tissue. Using them, scientists can grow mini organs of various types for research purposes, and, not surprisingly, there's a lot of interest in min...

How financial insecurity sinks American IQ scores

Not being able to pay your bills has the functional equivalent of lowering your IQ by 13 points. Many Americans have scarcity mindsets because of their inability to pay their bills. In a scarcity mindset, your functional bandwidth decreases — it influences you to be less generous and less reasonable. The opposite of a mindset of scarcity is a mindset of abundance, which is what many entrepreneurs have. Abundance mindsets tend to build on to themselves if the environment is right. ...

Sleep is a brain-repair mechanism, new study proves

Scientists Lior Appelbaum and David Zada in Israel publish new proof that sleep serves to help our brains repair damage. Their study, published in the journal Nature, used genetically engineering transparent zebrafish with colorful chemical tags attached to chromosomes in their neurons, and found that chromosomes constantly change shape to repair DNA damage, but move twice as much during sleep as when awake. “I think this is one of the key reasons we need to sleep,” said Lior Appelbaum from B...

Should you listen to music while doing intellectual work? It depends on the music, the task, and your personality

Given how many of us listen to music while studying or doing other cerebral work, you'd think psychology would have a set of clear answers as to whether the practice is likely to help or hinder performance. In fact, the research literature is rather a mess (not that that has deterred some enterprising individuals from making bold claims).There's the largely discredited "Mozart Effect" – the idea that listening to classical music can boost subsequent IQ, except that when first documented in the 9...

The evolution of mathematics, from agriculture to quantum mechanics

Mathematics has snowballed from counting to 10 on our fingers, to calculus, to abstract concepts like imaginary numbers that move in 11 dimensions and predict particles physics.The math that led us down the rabbit hole of quantum mechanics is bizarre and while we can crunch the numbers, we can't really understand what they mean. If the math confirms that particles can move in 11 dimensions, is that a fundamental truth of the universe?

The biggest A.I. risks: Superintelligence and the elite silos

What if you were immune to chronic pain? Vaccines could make it happen.

Alzheimer's disease and unintentional deaths (like opioid overdoses and suicides) have been driving down U.S. longevity statistics for three consecutive years – a trend not seen since the Spanish flu pandemic.

Scientists are developing vaccines for migraines and sciatica, which will lower the need for opioids, be cheaper, and make dr...
