Ground-Breaking Discovery: Our Earth emits a pulse every 26 seconds, and no one exactly knows why

Posted by in category: futurism

Have you ever wondered if the Earth has a heartbeat? Well, it turns out that our planet does pulsate every 26 seconds, and scientists have no idea why.

This mysterious phenomenon has been detected by seismometers across the world for more than half a century, but its origin and meaning remain unknown.

Sphere Las Vegas introduces ‘life-like’ robots to interact with guests at venue

Posted by in category: robotics/AI

LAS VEGAS, Nev. (FOX5) — The Sphere in Las Vegas has introduced “life-like” robots that will interact with guests at the venue.

According to a news release, the Sphere describes the creation, which is named Aura, as the “world’s most advanced humanoid robot.”

Serving as the Sphere’s “spokesbot,” Aura will permanently reside in the grand atrium at the venue.

Ultrathin nanotech promises to help tackle antibiotic resistance

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

The innovation – which has undergone advanced pre-clinical trials – is effective against a broad range of drug-resistant bacterial cells, including ‘golden staph’, which are commonly referred to as superbugs.

Antibiotic resistance is a major global health threat, causing about 700,000 deaths annually, a figure which could rise to 10 million deaths a year by 2050 without the development of new antibacterial therapies.

The new study led by RMIT University and the University of South Australia (UniSA) tested black phosphorus-based nanotechnology as an advanced infection treatment and wound healing therapeutic.

Transplant of fresh brain cells replaces diseased and aged ones

Posted by in categories: biotech/medical, neuroscience

Researchers have transplanted cells capable of forming specialized brain support cells into mice brains and found that they not only competed with and replaced unhealthy cells but aged ones, too. The findings open the door to developing an effective treatment for a range of conditions like multiple sclerosis, ALS, Alzheimer’s disease, autism and schizophrenia.

‘Glial cells’ is an umbrella term for the cells that are a support system to nerve cells (neurons). Progenitor cells are descendants of stem cells that can differentiate into specific cell types, and, in the case of glial cells, human glial progenitor cells (hGPCs) differentiate into subtypes, including astrocytes and oligodendrocytes, specialized for particular functions.

Astrocytes comprise most of our central nervous system cells, providing support and protection for neurons, transporting nutrients and removing waste. Oligodendrocytes lay down and maintain the lipid-rich, insulating wrapping called myelin around some axons, the part of the neuron that connects with another neuron and allows the transmission of nerve impulses.

A Cracked Piece of Metal Healed Itself in an Experiment That Stunned Scientists

Posted by in category: engineering

File this under ‘That’s not supposed to happen!’: Scientists observed a metal healing itself, something never seen before. If this process can be fully understood and controlled, we could be at the start of a whole new era of engineering.

A team from Sandia National Laboratories and Texas A&M University was testing the resilience of the metal, using a specialized transmission electron microscope technique to pull the ends of the metal 200 times every second. They then observed the self-healing at ultra-small scales in a 40-nanometer-thick piece of platinum suspended in a vacuum.

Cracks caused by the kind of strain described above are known as fatigue damage: repeated stress and motion that causes microscopic breaks, eventually causing machines or structures to break. Amazingly, after about 40 minutes of observation, the crack in the platinum started to fuse back together and mend itself before starting again in a different direction.

Flying the F-35 stealth fighter can leave pilots looking ‘like they are 100 years old,’ says test pilot

Posted by in category: military

F-35 test pilots described how intense it is to fly the aircraft, The Jerusalem Post reported.

“It’s like an 800-pound gorilla sitting on your chest,” a pilot said in a Lockheed Martin webinar.

“After some training, pilots come out looking like they are 100 years old,” another test pilot said.

Where Imagination Lives in Your Brain

Posted by in categories: biotech/medical, neuroscience

Henry Molaison, known for years as “H.M.,” was famously unable to form new memories. If someone he had met left the room only to return several minutes later, he would greet that person again as if for the first time. Because of surgery to treat intractable epilepsy, H M. lacked a sea-horse-shaped brain structure called the hippocampus and had amnesia. His case helped establish the hippocampus as an engine of memory.

In recent years scientists have discovered another essential deficit that burdens people with hippocampal amnesia: they can’t envision the range of possibilities that must be considered to make future plans. When researchers asked a group of people with hippocampal damage to… More.


The ability to conjure up possible futures or alternative realities is the flip side of memory. Both faculties cohabit in the brain region called the hippocampus.

Alzheimer’s Proteins Reduced by Sleep Drug

Posted by in categories: biotech/medical, neuroscience

Suvorexant (Belsomra), a dual orexin receptor antagonist approved for insomnia, reduced levels of tau phosphorylation and amyloid beta, a small clinical trialopens in a new tab or window showed.

The ratio of phosphorylated tau-threonine-181 (p-tau-181) to unphosphorylated tau-threonine-181 decreased 10% to 15% in cognitively normal adults treated with suvorexant 20 mg compared with placebo, reported Brendan Lucey, MD, MSCI, of Washington University School of Medicine in St. Louis, and co-authors.

Amyloid-beta levels fell 10% to 20% compared with placebo starting 5 hours after suvorexant administration, the researchers wrote in Annals of Neurologyopens in a new tab or window.

Study Says Staying Positive About Aging May Help Reverse Cognitive Decline

Posted by in categories: life extension, neuroscience

The researchers found those who showed positive age beliefs were 30% more likely to recover from cognitive impairment than those who held negative age beliefs, irrespective of the severity of the cognitive decline. The time for recovery was also quicker in people with positive age beliefs.

They also found that the participants who stayed positive about aging were less likely to develop mild cognitive impairment over 12 years.


It is widely believed that memory loss associated with aging is irreversible. However, a new study says people who embrace aging positively may recover from cognitive decline.
