20+ Popular Heuristics And Cognitive Biases

Posted by in category: neuroscience

We believe that reality is exactly what we perceive but really, this is just an illusion of our own brain. This happens because our brain takes shortcuts to interpret information and adapt to our surroundings: heuristics on which the brain relies to understand the reality perceived, but… can we always trust our brain when it utilizes these resources?

New research uncovers potential trigger for Type 2 diabetes

Posted by in categories: biotech/medical, food, health

Research led by the University of California, Los Angeles (UCLA) has uncovered a new process that may help explain how Type 2 diabetes develops. In tests on live mice and human cells in the lab, the team found a new mechanism besides insulin resistance and high glucose levels that triggers pancreatic cells to begin overproducing insulin.

Type 2 diabetes is the form of the disease that’s usually a result of lifestyle choices, such as poor diet and not enough exercise. It involves a kind of vicious cycle of insulin – beta cells in the pancreas produce too much insulin, which causes the body to become resistant to it. That in turn means the beta cells could produce even more to compensate.

It was long thought that high glucose levels – most commonly caused by eating too much sugary and fatty foods – was the trigger for the beta cells to begin overproducing insulin. But it’s also been shown in the past that even beta cells isolated in a lab dish can over-secrete insulin, without glucose playing a part.

This ultracool smart glove for astronauts is like a remote control for robots on the Moon and Mars

Posted by in categories: cyborgs, drones, robotics/AI, space travel

What if astronauts could take a spacecraft to Mars or some other alien planet and, without ever flying through a toxic atmosphere or landing on an inhospitable surface, control drones and rovers to unearth things that would be otherwise impossible to get up close to?

This is the thinking behind the Ntention smart glove. Ntention is an ambitious futuretech startup that was the brainchild of Norwegian University of Science and Technology (NTNU) students who wanted to push the limits of space exploration. They designed this glove, equipped with sensors, as a human-machine interface that lets you mind-control a robot with hand gestures. Now NASA’s Haughton Mars project (HMP) has field tested the glove and found it to be many levels of awesome.

Paralyzed Canadian says experimental spinal stimulator improves quality of life

An Ontario woman who was part of a U.S. study on experimental spinal stimulators similar to the device implanted in a paralyzed Humboldt Broncos player in Thailand says the device should be tested in Canada where it is not approved for use.

America’s newest national park is a massive sand dune

Posted by in category: education

White Sands National Monument in New Mexico is now White Sands National Park.

On Friday, President Donald Trump signed the National Defense Authorization Act for Fiscal Year 2020 that, among many other things, stripped away the monument status and upgraded it to “national park.” The 275 square miles of desert filled with gypsum sand dunes in southern New Mexico became the 62nd national park in the federal system.

The act proclaims the establishment of White Sands Park is intended “to protect, preserve, and restore its scenic, scientific, educational, natural, geological, historical, cultural, archaeological, paleontological, hydrological, fish, wildlife, and recreational values and to enhance visitor experiences…”

MIT reveals first ever laser ultrasound pictures of a human body

Posted by in category: biotech/medical

Researchers from MIT have revealed the very first images of a human generated through a novel laser ultrasound imaging technique. Unlike conventional ultrasound, the new technique does not require any skin contact with the body, dramatically amplifying the range of uses for doctors in clinical environments.

A conventional ultrasound is one of the cheapest and easiest imaging methods clinicians currently have in their arsenal. Unlike X-ray or CT scans, an ultrasound does not involve harmful radiation, and unlike PET or MRI scans, there is no need for large expensive machines. Of course, ultrasound does have a number of limitations, from the need for significant bodily contact in the process of imaging, to a variability in imaging results.

A new non-contact ultrasound method involving lasers has now been effectively demonstrated by a team of researchers from MIT. The challenge in developing the new method has been figuring out a way to use a laser to produce sound waves. Traditional ultrasound uses sound waves to penetrate a human body and bounce back off different tissues. Light, of course, cannot penetrate a human body as deeply as sound.

We’ve just had the best decade in human history. Seriously

Posted by in categories: biotech/medical, economics, sustainability

Let nobody tell you that the second decade of the 21st century has been a bad time. We are living through the greatest improvement in human living standards in history. Extreme poverty has fallen below 10 percent of the world’s population for the first time. It was 60 percent when I was born. Global inequality has been plunging as Africa and Asia experience faster economic growth than Europe and North America; child mortality has fallen to record low levels; famine virtually went extinct; malaria, polio and heart disease are all in decline.

Little of this made the news, because good news is no news. But I’ve been watching it all closely. Ever since I wrote The Rational Optimist in 2010, I’ve been faced with ‘what about…’ questions: what about the great recession, the euro crisis, Syria, Ukraine, Donald Trump? How can I possibly say that things are getting better, given all that? The answer is: because bad things happen while the world still gets better. Yet get better it does, and it has done so over the course of this decade at a rate that has astonished even starry-eyed me.

Perhaps one of the least fashionable predictions I made nine years ago was that ‘the ecological footprint of human activity is probably shrinking’ and ‘we are getting more sustainable, not less, in the way we use the planet’. That is to say: our population and economy would grow, but we’d learn how to reduce what we take from the planet. And so it has proved. An MIT scientist, Andrew McAfee, recently documented this in a book called More from Less, showing how some nations are beginning to use less stuff: less metal, less water, less land. Not just in proportion to productivity: less stuff overall.

Is intermittent fasting the longevity life hack we’ve been waiting for?

Posted by in categories: food, life extension

Intermittent fasting means interspersing periods of abstaining from food with periods of eating regularly. You could skip breakfast and eat a late lunch, for example, or fast all day long, once or twice a week.

The research suggests that intermittent fasting is a simple, effective life hack for solving many age-related problems, but the evidence is far from conclusive.

“There really is no one weird trick for the perfect diet for everyone,” John Newman, geriatrician at the University of California, San Francisco told Inverse. Science is leading us toward the idea of maintaining some flexibility in our body’s metabolism, he said.
