Thousands of humanoid robots set to be produced this year

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

The makers of Sophia the robot are set to mass produce thousands of humanoid machines starting this year.

Hong-Kong based company Hanson Robotics will roll out four new models in the first half of 2021 after its humanoid robot Sophia went viral in 2016.

Adding or subtracting single quanta of sound

Posted by in categories: particle physics, quantum physics

Researchers perform experiments that can add or subtract a single quantum of sound—with surprising results when applied to noisy sound fields.

Quantum mechanics tells us that physical objects can have both wave and particle properties. For instance, a single particle—or quantum—of is known as a photon, and, in a similar fashion, a single quantum of sound is known as a phonon, which can be thought of as the smallest unit of sound energy.

A team of researchers spanning Imperial College London, University of Oxford, the Niels Bohr Institute, University of Bath, and the Australian National University have performed an experiment that can add or subtract a single phonon to a high-frequency sound field using interactions with .

Scientists use a novel ink to 3D print bone with living cells

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

Scientists from UNSW Sydney have developed a ceramic-based ink that may allow surgeons in the future to 3D-print bone parts complete with living cells that could be used to repair damaged bone tissue.

Using a 3D-printer that deploys a special ink made up of calcium phosphate, the scientists developed a new technique, known as ceramic omnidirectional bioprinting in cell-suspensions (COBICS), enabling them to print -like structures that harden in a matter of minutes when placed in water.

While the idea of 3D-printing bone-mimicking structures is not new, this is the first time such material can be created at room temperature—complete with living cells—and without harsh chemicals or radiation, says Dr. Iman Roohani from UNSW’s School of Chemistry.

3D-Printed Nanosatellite Thruster Emits Pure Ions for Propulsion

Posted by in categories: nanotechnology, satellites

Study is first demonstration of a fully 3D-printed thruster using pure ion emission for propulsion.

A 3D-printed thruster that emits a stream of pure ions could be a low-cost, extremely efficient propulsion source for miniature satellites.

The nanosatellite thruster created by MIT researchers is the first of its kind to be entirely additively manufactured, using a combination of 3D printing and hydrothermal growth of zinc oxide nanowires. It is also the first thruster of this type to produce pure ions from the ionic liquids used to generate propulsion.

Phase Four launches first plasma propulsion systems

Posted by in category: satellites

WASHINGTON — Electric propulsion company Phase Four flew its first plasma thrusters on two spacecraft that were part of a SpaceX dedicated rideshare launch Jan. 24.

Phase Four said its Maxwell plasma propulsion systems were on two of the 143 spacecraft launched on the Transporter-1 mission. The company declined to name the satellites at the request of its customer, which is flying an operational mission but is also testing other new designs on those spacecraft.

The thrusters on those two satellites are the first developed by Phase Four, founded in 2015, to fly in space. In an interview, Beau Jarvis, chief executive of the company, said the company eschewed an approach of quickly building and flying a technology demonstration and then raising money to build a commercial model.

Scientists Create Quantum System That Stays Operational 10,000 Longer

Posted by in category: quantum physics

“With this approach, we don’t try to eliminate noise in the surroundings; instead, we “trick” the system into thinking it doesn’t experience the noise,” first author Kevin Miao, postdoctoral researcher at UChicago, said in the statement.

They used both electromagnetic pulses and a continuous alternating magnetic field to keep the quantum system under control. They then tuned this magnetic field in just such a way, that the rest of the noise was simply tuned out.

“To get a sense of the principle, it’s like sitting on a merry-go-round with people yelling all around you,” Miao explained in the statement. “When the ride is still, you can hear them perfectly, but if you’re rapidly spinning, the noise blurs into a background.”

Ginger may counter some autoimmune diseases, says new study

Posted by in category: biotech/medical

Specifically, the researchers looked at lupus, which attacks the body’s own immune system, along with antiphospholipid syndrome (often associated with lupus), which causes blood clots. Both the diseases cause widespread inflammation and ravage organs overtime. In mice with either of the disease, 6-gingerol stopped the neutrophil extracellular trap release caused by the diseases’ production of autoantibodies.

“Neutrophil extracellular traps, or NETs, come from white blood cells called neutrophils,” explained lead author Ramadan Ali, Ph.D in a press release. “These sticky spider-web like structures are formed when autoantibodies interact with receptors on the neutrophil’s surface.”

The webs, according to Ali, play a fundamental role in the pathogenesis of lupus and antiphospholipid syndrome in which they set off autoantibody formation and contribute to clots in blood vessels and other damage.

Shoot for the Moon: Its Surface Contains a Pot of Gold

Posted by in categories: biotech/medical, military, nuclear energy, terrorism

Here’s a riddle: What do the Moon, nuclear weapons, clean energy of the future, terrorism, and lung disease all have in common?

The answer is helium-3, a gas that’s extremely rare on Earth but 100 million times more abundant on the Moon.


The capability to show anatomic details of the lungs and airways, and the ability to display functional imaging as a patient breathes, makes helium-3 MRI far better than the standard method of testing lung function. Called spirometry, this method tells physicians how the lungs function overall, but does not home in on particular areas that may be causing a problem. Plus, spirometry requires patients to follow instructions and hold their breath, so it is not great for testing young children with pulmonary disease.
