Earth Views from the Space Station

Behold, the Earth! See live views of Earth from the coming to you by NASA’s High Definition Earth Viewing (HDEV) experiment.

Behold, the Earth! See live views of Earth from the International Space Station coming to you by NASA’s High Definition Earth Viewing (HDEV) experiment.

While the experiment is operational, views will typically sequence through the different cameras. If you are seeing a black image, the Space Station is on the night side of the Earth. If you are seeing an image with text displayed, the communications are switching between satellites and camera feeds are temporarily unavailable. Between camera switches, a black & gray slate will also briefly appear.

Russian scientists 3D printing biological tissues with magnets in microgravity

Posted by in categories: 3D printing, bioprinting, biotech/medical, nanotechnology

3D bioprinting is a process for patterning and assembling complex functional living architectures in a gradient fashion. Generally, 3D bioprinting utilizes the layer-by-layer method to deposit materials known as bioinks to create tissue-like structures. Several 3D bioprinting techniques have been developed over the last decade, for example, magnetic bioprinting, a method that employs biocompatible magnetic nanoparticles to print cells into 3D structures.

But now a Russian research team has developed a new method of bioprinting that allows to create 3D biological objects without the use of layer-by-layer approach and magnetic labels. The new method, which involves magnetic levitation research in conditions of microgravity, was conducted by the 3D Bioprinting Solutions company in collaboration with other Russian and foreign scientists, including the Joint Institute for High Temperatures of the Russian Academy of Sciences (JIHT RAS).

Why Quantum Computers Will Be Super Awesome, Someday

Posted by in categories: augmented reality, quantum physics, robotics/AI

Satya Nadella, the chief executive officer of Microsoft Corp., calls quantum computing one of three emerging technologies that will radically reshape the world, along with artificial intelligence and augmented reality. But it’s easier to describe quantum computing’s importance — that is, its potential importance, because it barely exists now — than to say what it is. Understanding quantum mechanics, whose principles underpin quantum computing, involves a lot of mental mountain climbing. Someth.

Neurotoxins and Sleep: What You Need to Know

Posted by in categories: biotech/medical, neuroscience

Living in a culture dependant upon caffeine and lack of sleep, its important to remember that sleep offers an incredibly important biological function. One night of sleep deprivation is tied to Alzheimer’s disease.

While people once believed that sleep was merely a period of inactivity and rest, modern studies in chronobiology have shown that sleep is important for a variety of biochemical processes. A recent study suggests that sleep is even more important than physicians and scientists previously thought, allowing the brain to flush out toxic chemicals that build up over the course of a day.

Power-multiplying exoskeletons are slimming down for use on the battlefield

Posted by in categories: cyborgs, energy, military

Dashing around a battlefield in the bulky robo-armor Tom Cruise wore in Edge of Tomorrow won’t cut it in the real world. For starters, it’s way too big. And the energy required to power something that size—via a gas engine strapped to your back in some early inventor iterations—is noisy and a giveaway to the enemy that you’re approaching.

But a raft of newly developed exoskeletons is starting to meet the slimmed-down, stealth requirements of today’s troop commanders, who see these power-assisting suits as vital to the future combat missions. Among the most promising, and weird-looking, is the “third arm” that the U.S. Army Research Laboratory developed to help soldiers carry and support their weapons on the battlefield. The lightweight device, which weighs less than four pounds and hangs at a soldier’s side, stabilizes rifles and machine guns, which can weigh up to 27 pounds. This improves shooting accuracy and also minimizes fatigue. It can even be used while scrambling into position on the ground.

The kind of fatigue that the third arm aims to negate is a killer on the battlefield, and most of the new suits are similarly meant to help troops minimize the energy they use to carry enormous supply packs, weapons and other battlefield gear. In May, Lockheed Martin unveiled its lightest weight powered exo for lower body support. Dubbed ONYX, the form-fitting suit, which resembles an unobtrusive web of athletic braces, reduce the effort soldier’s need for walking, running, and climbing over varied terrain while carrying a heavy loads of up to 100 pounds.

‘Breakthrough’ algorithm exponentially faster than any previous one

Posted by in categories: biotech/medical, information science, robotics/AI

What if a large class of algorithms used today—from the algorithms that help us avoid traffic to the algorithms that identify new drug molecules—worked exponentially faster?

Computer scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a completely new kind of algorithm, one that exponentially speeds up computation by dramatically reducing the number of parallel steps required to reach a solution.

The researchers will present their novel approach at two upcoming conferences: the ACM Symposium on Theory of Computing (STOC), June 25–29 and International Conference on Machine Learning (ICML), July 10 −15.

A New Study Is Questioning The Limits of Human Lifespan

Posted by in category: life extension

Jeanne Louise Calment lived for 122 years and 164 days, the oldest verified age of any person, ever. Her interviews revealed a portrait of the centenarian in high spirits: “I’ve only ever had one wrinkle, and I’m sitting on it,” she told reporters when she turned 110.

Calment died in 1997 in Arles, France, where she spent much of her impressively long life. No one else, according to accurate records, has lived beyond 120 years.

Whether there’s a limit to the human life span is an age-old question. An actuary named Benjamin Gompertz proposed in 1825 that mortality rates accelerate exponentially as we grow older.

The State of Brain-Machine Interfaces

Posted by in categories: biotech/medical, genetics, neuroscience

Maryam shanechi, university of southern california.

With recent technological advances, we can now record neural activity from the brain, and manipulate this activity with electrical or optogenetic stimulation in real time. These capabilities have brought the concept of brain-machine interfaces (BMI) closer to clinical viability than ever before. BMIs are systems that monitor and interact with the brain to restore lost function, treat neurological disorders, or enhance human performance.
