Chemical cocktail creates new avenues for generating muscle stem cells

Posted by in categories: biotech/medical, chemistry

A UCLA-led research team has identified a chemical cocktail that enables the production of large numbers of muscle stem cells, which can self-renew and give rise to all types of skeletal muscle cells.

Researchers help keep pace with Moore’s Law

Posted by in categories: computing, engineering

Progress in the field of integrated circuits is measured by matching, exceeding, or falling behind the rate set forth by Gordon Moore, former CEO and co-founder of Intel, who said the number of electronic components, or transistors, per integrated circuit would double every year. That was more than 50 years ago, and surprisingly his prediction, now called Moore’s Law, came true.

In recent years, it was thought that the pace had slowed; one of the biggest challenges of putting more circuits and power on a smaller chip is managing heat.

A multidisciplinary group that includes Patrick E. Hopkins, a professor in the University of Virginia’s Department of Mechanical and Aerospace Engineering, and Will Dichtel, a professor in Northwestern University’s Department of Chemistry, is inventing a new class of material with the potential to keep chips cool as they keep shrinking in size—and to help Moore’s Law remain true. Their work was recently published in Nature Materials.

Dark Origins of One of Jupiter’s Grand Light Shows Revealed by NASA’s Juno Spacecraft

Posted by in category: space

The gas-giant orbiter is illuminating the provenance of Jovian polar light shows.

New results from the Ultraviolet Spectrograph instrument on NASA ’s Juno mission reveal for the first time the birth of auroral dawn storms – the early morning brightening unique to Jupiter ’s spectacular aurorae. These immense, transient displays of light occur at both Jovian poles and had previously been observed only by ground-based and Earth-orbiting observatories, notably NASA’s Hubble Space Telescope. Results of this study were published March 16 in the journal AGU Advances.

First discovered by Hubble’s Faint Object Camera in 1994, dawn storms consist of short-lived but intense brightening and broadening of Jupiter’s main auroral oval – an oblong curtain of light that surrounds both poles – near where the atmosphere emerges from darkness in the early morning region. Before Juno, observations of Jovian ultraviolet aurora had offered only side views, hiding everything happening on the nightside of the planet.

GOTHAM Investigators Uncover Warehouse-Full of Complex Molecules Never Before Seen in Space

Posted by in categories: materials, space

Radio observations of a cold, dense cloud of molecular gas reveal more than a dozen unexpected molecules.

Scientists have discovered a vast, previously unknown reservoir of new aromatic material in a cold, dark molecular cloud by detecting individual polycyclic aromatic hydrocarbon molecules in the interstellar medium for the first time, and in doing so are beginning to answer a three-decades-old scientific mystery: how and where are these molecules formed in space?

“We had always thought polycyclic aromatic hydrocarbons were primarily formed in the atmospheres of dying stars,” said Brett McGuire, Assistant Professor of Chemistry at the Massachusetts Institute of Technology, and the Project Principal Investigator for GOTHAM, or Green Bank Telescope (GBT) Observations of TMC-1: Hunting Aromatic Molecules. “In this study, we found them in cold, dark clouds where stars haven’t even started forming yet.”

Endoscopy-assisted magnetic navigation of biohybrid soft microrobots with rapid endoluminal delivery and imaging

Posted by in category: biotech/medical

High-precision delivery of microrobots at the whole-body scale is of considerable importance for efforts toward targeted therapeutic intervention. However, vision-based control of microrobots, to deep and narrow spaces inside the body, remains a challenge. Here, we report a soft and resilient magnetic cell microrobot with high biocompatibility that can interface with the human body and adapt to the complex surroundings while navigating inside the body. We achieve time-efficient delivery of soft microrobots using an integrated platform called endoscopy-assisted magnetic actuation with dual imaging system (EMADIS).

Researchers combines AI and robotic exoskeleton to make a self walking robotics exoskeleton

Posted by in categories: cyborgs, mobile phones, robotics/AI

Robotics researchers are developing exoskeleton legs capable of thinking and making control decisions on their own using artificial intelligence called ExoNet

THE PROBLEM

Current generation of exoskeleton legs need to be manually controlled by users via smartphones or joysticks, It has a problem where motors need to change their operating mode manually when they perform a new activity in different terrains.

New Apple Mixed-Reality Headset Details: Swappable Headbands, Eye-Tracking

Posted by in category: futurism

A mixed-reality headset Apple is developing will be equipped with more than a dozen cameras for tracking hand movements and showing video of the real world to people wearing it, along with ultra-high-resolution 8K displays and advanced technology for eye tracking, according to a person with direct knowledge of the device.

Those are among a bevy of features Apple is planning for the headset, a device that could represent one of the company’s most ambitious efforts to build a new technology platform. The Information viewed internal Apple images of a late-stage prototype from last year, which show a sleek, curved visor attached to the face by a mesh material and swappable headbands. An artist’s rendering based on the images of the headset and created by The Information appears below.

Ageing: Looming crisis or booming opportunity?

By 2050, the number of adults over the age of 65 globally will double, reaching a staggering 1.6 billion, with the largest growth in the developing world. This growth will be one of the greatest social, economic, and political transformations of our time, that will impact existing healthcare, government and social systems, that today are largely not inclusive of the ageing population or built to the scale needed to support it.

But we can begin to make investments in our support systems (enabled and scaled by technology) that encompass a coordinated response from governments, society, academia, and the private sector.
