Today I Learned That Not Everyone Has An Internal Monologue And It Has Ruined My Day

Posted by in category: futurism

My day was completely ruined yesterday when I stumbled upon a fun fact that absolutely obliterated my mind. I saw this tweet yesterday that said that not everyone has an internal monologue in their head. All my life, I could hear my voice in my head and speak in full sentences as if I was talking out loud. I thought everyone experienced this, so I did not believe that it could be true at that time.

Literally the first person I asked was a classmate of mine who said that she can not “hear” her voice in her mind. I asked her if she could have a conversation with herself in her head and she looked at me funny like I was the weird one in this situation. So I began to become more intrigued. Most peo ple I asked said that they have this internal monologue that is running ram pant throughout the day. However, every once in a while, someone would say that they don’t experience this.

WHO declares China coronavirus that’s killed 171 a global health emergency

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

The World Health Organization said the fast-spreading coronavirus that’s infected more than 8,200 people across the world is a global health emergency — a rare designation that helps the international agency mobilize financial and political support to contain the outbreak.

The announcement comes just hours after the U.S. confirmed its first human-to-human transmission of the virus, which has killed at least 171 people in China and has now spread to at least 18 other countries.

Since emerging less than a month ago in Wuhan, China, the coronavirus has infected more people than the 2003 SARS epidemic, which sickened roughly 8,100 people across the globe over nine months. As of Thursday, there are at least eight cases in four countries, outside of China, of human-to-human transmission of the new coronavirus.

Fish that can repair their OWN HEART: Scientists discover how

Posted by in category: biotech/medical

Scientists are one step closer to understanding how fish can repair their own heart, offering clues for treatment in millions of heart attack patients.

Zebrafish, a Mexican fish, are often the focus of scientific research because they are known to remarkably regenerate their own heart tissue.

University of Oxford scientists were ‘surprised’ to find that immune cells, called macrophages, were involved in the process.

A Nanoparticle Trojan Horse Approach to Atherosclerosis

Posted by in categories: biotech/medical, nanotechnology

Researchers from Stanford University and Michigan State University have teamed up to create a nanoparticle that can eat away at the arterial plaques that lead to strokes and heart attacks in a mouse model of atherosclerosis.

The team has created a nanoparticle that acts like a Trojan horse, targeting atherosclerotic plaque to reduce its amount and prevent it from getting out of control. A considerable amount of plaque material consists of dead and dying macrophages, a type of immune cell, which have become trapped and overwhelmed while trying to remove debris and fatty deposits. As these cells die, they attract more macrophages which arrive to try to clear up the waste; they too become trapped, and this is the foundation of atherosclerotic plaque.

The new study demonstrates how the nanoparticle is able to locate the plaque while showing high selectivity for macrophages [1]. Once it has located its target, the nanoparticle enters the macrophages within the plaque and delivers a drug payload to the cells, encouraging the macrophages to engulf and consume cellular debris. Essentially, this means that the macrophages eat the dead and dying cells within the plaque and thus reduce its overall size.

How Mini Sabbaths Will Save Your Brain

Posted by in categories: computing, health, neuroscience

Have humans become an indoor species? Given that Americans spend, on average, 93 percent of their time indoors, it would seem that we are indeed suffering from what some call “nature deficit disorder.”

We don’t need a fancy term to realize we might benefit from spending more time outdoors. Getting out for a gentle walk or a vigorous hike is likely to reduce stress, improve health, and increase emotional well-being.

If you spend much time on a computer, you probably reach a time in the day when you have so many browser tabs and programs open that your computer slows considerably. It’s time for a reset.

Stress test reveals graphene won’t crack under pressure

Posted by in categories: engineering, materials

Graphene is a paradox. It is the thinnest material known to science, yet also one of the strongest. Now, research from University of Toronto Engineering shows that graphene is also highly resistant to fatigue—able to withstand more than a billion cycles of high stress before it breaks.

CDC confirms first human-to-human transmission of coronavirus in US

Posted by in categories: biotech/medical, health

“This is a very serious public health situation,” said Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases. “Moving forward, we can expect to see more cases, and more cases means more potential for person-to-person spread.”

The virus, which emerged Dec. 31, has already spread to more people than the 2003 SARS epidemic, which sickened roughly 8,100 people across the globe over nine months. The transmission makes the U.S. at least the fifth country where the infection is now spreading through human-to-human contact, including China. Officials of the Centers for Disease Control and Prevention said there are at least nine cases of human-to-human transmission outside of China, as of Thursday.

As of Thursday afternoon, 8,137 cases were confirmed in mainland China alone, according to Chinese state media, and more than 100 cases were confirmed elsewhere around the world — bringing the global total to at least 8,248.

DARPA’s call for robot drone ships Reports

Posted by in categories: drones, robotics/AI

The Defense Advanced Research Project Agency has set its sights on a new kind of drone ship — one that doesn’t contemplate a human ever setting foot on it. Dubbed NOMARS (No Manning Required, Ship), the new ships could feature radical new designs and cut costs by removing any elements normally needed to accommodate people.
