A new measurement record for strongest magnetic field in universe

Posted by in categories: energy, space

Breaking the previous record by 60 percent.

The team behind the first Chinese X-ray astronomy satellite, Insight-HXMT, has discovered the strongest magnetic field directly measured in the universe hitherto.

It is a known fact that neutron stars generate the strongest magnetic fields in the universe. These magnetic fields, close to a neutron star’s surface, can only be measured accurately and directly by looking for cyclon resonance scattering features (CRSF). The Insight-HXMT team discovered a cyclotron absorption line with an energy of 146 keV in the neutron star X-ray binary Swift J0243.6+6124, which translates to a surface magnetic field of more than 1.6 billion Tesla.

New kind of laser uses tiny particle clumps to generate light

Posted by in category: particle physics

Lasers normally use mirrors to create laser light, but a new kind uses clumps of moving particles. The result is a laser that is more programmable and could generate extra-sharp visual displays.

TRISO Particles: The Most Robust Nuclear Fuel on Earth

Posted by in categories: nuclear energy, particle physics

TRISO particles cannot melt in a reactor and can withstand extreme temperatures well beyond the threshold of current nuclear fuels.

There’s a lot of buzz around advanced nuclear.

These technologies are going to completely change the way we think about nuclear reactors.

Providing embedded artificial intelligence with a capacity for palimpsest memory storage

Posted by in categories: biological, chemistry, robotics/AI

Biological synapses are known to store multiple memories on top of each other at different time scales, much like representations of the early techniques of manuscript writing known as “palimpsest,” where annotations can be superimposed alongside traces of earlier writing.

Biological palimpsest consolidation occurs via hidden that govern synaptic efficacy at varying lifetimes. The arrangement can facilitate idle memories to be overwritten without forgetting them, while using previously unseen memories short-term. Embedded can significantly benefit from such functionality; however, the hardware has yet to be demonstrated in practice.

In a new report, now published in Science Advances, Christos Giotis and a team of scientists in Electronics and Computer Science at the University of Southampton and the University of Edinburgh, U.K., showed how the intrinsic properties of metal-oxide volatile memristors mimicked the process of biological palimpsest consolidation.

Atomic level deposition to extend Moore’s law and beyond

Posted by in categories: computing, materials

Moore’s law has driven the semiconductor industry to continue downscaling the critical size of transistors to improve device density. At the beginning of this century, traditional scaling started to encounter bottlenecks. The industry has successively developed strained Si/Ge, high-K/metal gate, and Fin-FETs, enabling Moore’s Law to continue.

Now, the critical size of FETs is down to 7 nm, which means there are almost 7 billion transistors per square centimeter on one chip, which brings huge challenges for fin-type structure and nanomanufacturing methods. Up to now, extreme ultraviolet lithography has been used in some critical steps, and it is facing alignment precision and high costs for high-volume manufacturing.

Meanwhile, the introduction of new materials and 3D complex structures brings serious challenges for top-down methods. Newly developed bottom-up manufacturing serves as a good complementary method and provides technical driving force for nanomanufacturing.

Scientists develop new method and device to isolate single cells using electric fields

Posted by in category: biotech/medical

In cancer research, it all comes down to a single cell.

Over the last decade, cancer researchers have homed in on the fact that an individual cell from a tumor can be used to perform molecular analyses that reveal important clues about how the cancer developed, how it spreads and how it may be targeted.

With this in mind, a team of researchers at Brown University has developed an advanced way to isolate single cells from complex tissues. In a study published in Scientific Reports, they show how the approach not only results in high-quality, intact single cells, but is also superior to standard isolation methods in terms of labor, cost and efficiency.

Type 3 diabetes: symptoms, causes and treatments

Posted by in categories: biotech/medical, neuroscience

The term ‘type 3 diabetes’ has been used by some to describe Alzheimer’s disease.


While most of us are familiar with type 1 and type 2 diabetes, you may not have come across the term ‘type 3 diabetes’ before. First things first, this is not to be confused with type 3c diabetes, which is something else entirely. It is, however, related to insulin resistance in the brain.

Being diagnosed as insulin resistant generally means that someone is either prebiabetic or has type 2 diabetes. But scientists have proposed that it can also result in the brain’s neurons lacking glucose, which is needed for proper function, and this can lead to symptoms of Alzheimer’s disease.
