A future kitchen appliance could make it possible to 3D-print entirely new recipes and cook them with lasers.

That is the long-term vision at Columbia University’s Creative Machines Lab, an engineering group that uses insight from biology to research and develop autonomous systems that “create and are creative.” The engineers have spent years working to digitize and automate the cooking process.

Last week, the James Webb Space Telescope (JWST) made the first ever detection of CO₂ on an exoplanet. Following that scientific milestone, it has now captured a direct image of another planet – HIP 65,426 b, which orbits the large A-type star HIP 65426. The system is 355 light years from Earth.

Astronomers first discovered this gas giant in July 2017, using the Spectro-Polarimetric High-Contrast Exoplanet Research (SPHERE) instrument belonging to the European Southern Observatory (ESO).

NASA made a follow-up observation to test Webb’s capabilities, using the mid-infrared part of the spectrum to reveal new information that previous telescopes would be unable to detect. The spacecraft’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) are both equipped with coronagraphs to block the glare of starlight, which can be 10,000 times brighter than planets. This enables Webb to take direct images of exoplanets.

2nd launch attempt scrubbed.

A fuel leak forced NASA to call off its second attempt to launch the Artemis 1 moon mission on Saturday (Sept. 3).

A combination of cutting-edge hardware, sensor technology, and bespoke machine learning approaches can predict trajectories of vehicles, people, and even animals, as far as 8 seconds into the future.

As space travel for recreational purposes is becoming a very real possibility, there could come a time when we are travelling to other planets for holidays, or perhaps even to live. Commercial space company Blue Origin has already started sending paying customers on sub-orbital flights. And Elon Musk hopes to start a base on Mars with his firm SpaceX.

This means we need to start thinking about what it will be like to live in space – but also what will happen if someone dies there.

After death here on Earth the human body progresses through a number of stages of decomposition. These were described as early as 1,247 in Song Ci’s The Washing Away of Wrongs, essentially the first forensic science handbook.

Scientists have worked out how to use an infrared laser to charge devices at a distance. The system can deliver up to 400 milliwatts of power up to a distance of 30 meters (100 feet). That amount of power is sufficient to charge small sensors and other tech, and with developments, it could be possible to charge mobile devices too.

The work, published in the journal Optics Express, focused on a method called distributed laser charging. They showed that an infrared laser (whose wavelength can’t harm skin or eyes) was shined through a spherical ball lens towards a device with a photovoltaic receiver of 10 by 10 millimeters (0.4 by 0.4 inches).

The receiver is small enough to be attached to many mobile devices and sensors, and the team showed that it was able to convert 400 milliwatts to 85 milliwatts of electrical power. A small but significant result.

A team of Japanese and US physicists has pushed thousands of Ytterbium atoms to just within a billionth of a degree above absolute zero to understand how matter behaves at these extreme temperatures. The approach treats the atoms as fermions, the type of particles like electrons and protons, that cannot end up in the so-called fifth state of matter at those extreme temperatures: a Bose-Einstein Condensate.

When fermions are actually cooled down, they do exhibit quantum properties in a way that we can’t simulate even with the most powerful supercomputer. These extremely cold atoms are placed in a lattice and they simulate a “Hubbard model” which is used to study the magnetic and superconductive behavior of materials, in particular the collective motion of electrons through them.

The symmetry of these models is known as the special unitary group, or, SU, and depends on the possible spin state. In the case of Ytterbium, that number is 6. Calculating the behavior of just 12 particles in a SU Hubbard model can’t be done with computers. However, as reported in Nature Physics, the team used laser cooling to reduce the temperature of 300,000 atoms to a value almost three billion times colder than the temperature of outer space.

Researchers at Intel Labs, in collaboration with the Italian Institute of Technology and the Technical University of Munich, have introduced a new approach to neural network-based object learning. The new approach specifically targets future robotics applications like robotic assistants that interact with unconstrained environments, which are present in situations such as logistics and healthcare.

The new research can prove crucial for improving the service or manufacturing capabilities of our future robots.

The research paper titled “Interactive continual learning for robots: a neuromorphic approach” was awarded “Best Paper” at the 2022 International Conference on Neuromorphic Systems (ICONS) hosted by Oak Ridge National Laboratory.

Scientists will soon begin a clinical trial for a new liver disease treatment. The experimental treatment will hopefully help treat end-stage liver disease and reduce liver transplants. To do this, it will harness the natural regenerative power of the liver by growing an entirely new liver within the patient. It won’t just rely on one new liver, either. Instead, patients will grow multiple tiny livers in their bodies.

The process, which has shown success in mice, pigs, and dogs, involves injecting healthy liver cells into the patient’s lymph nodes. The cells then multiply inside the patient’s body, growing into tiny functioning versions of the larger organ. It’s an intriguing treatment for liver disease, and so far, it has improved liver function in animals that have received the treatment.
