Origami robots are autonomous machines that are constructed by folding two-dimensional materials into complex, functional three-dimensional structures. These robots are highly versatile. They can be designed to perform a wide range of tasks, from manipulating small objects to navigating difficult terrain. Their compact size and flexibility allow them to move in ways that traditional robots cannot, making them ideal for use in environments that are hard to reach.

Another notable feature of origami-based robots is their low cost. Because they are constructed using simple materials and techniques, they can be produced relatively inexpensively. This makes them an attractive option for many researchers and companies looking to develop new robotics applications.

There are many potential applications for origami robots. They could be used in search and rescue missions, where their small size and flexibility would allow them to navigate through rubble and debris. They could also be used in manufacturing settings, where their ability to manipulate small objects could be put to use in assembly lines.

According to reports, the Taiwanese computer hardware company MSI (Micro-Star International) was recently joined to the list of victims of a new ransomware gang that goes by the name “Money Message.” The perpetrators of the cybercrime say that they have taken source code along with other critical material from the company’s network. MSI is a world-renowned leader in the production of computer components, such as motherboards, graphics cards, desktop computers, laptop computers, servers, and other electronic equipment. It brings in more than $6.5 billion in income every year.

Money Message has included MSI on the website that it maintains for the publication of leaked material and has published images of the company’s CTMS and ERP databases in addition to files that include software source code, private keys, and BIOS firmware. If MSI does not comply with the threat actors’ demand for a ransom payment, they will now threaten to release all of the information that was taken.

The perpetrators of the hack claim to have taken 1.5 terabytes worth of data, including databases and source code, from MSI’s servers. They are holding out for a ransom payment of four million dollars.

To take a picture, the best digital cameras on the market open their shutter for around around one four thousandths of a second.

To snapshot atomic activity, you’d need a shutter that clicks a lot faster.

Now scientists have come up with a way of achieving a shutter speed that’s a mere trillionth of a second, or 250 million times faster than those digital cameras. That makes it capable of capturing something very important in materials science: dynamic disorder.

There’s enough trouble on this planet already that we don’t need new problems coming here from the sun. Unfortunately, we can’t yet destroy this pitiless star, so we are at its mercy. But NASA at least may soon be able to let us know when one of its murderous flares is going to send our terrestrial systems into disarray.

Understanding and predicting space weather is a big part of NASA’s job. There’s no air up there, so no one can hear you scream, “Wow, how about this radiation!” Consequently, we rely on a set of satellites to detect and relay this important data to us.

One such measurement is of solar wind, “an unrelenting stream of material from the sun.” Even NASA can’t find anything nice to say about it! Normally this stream is absorbed or dissipated by our magnetosphere, but if there’s a solar storm, it may be intense enough that it overwhelms the local defenses.

This novel technology looks like a sci-fi device. But it’s real.

It seems like something from a science fiction movie: a specialized, electronic headband and using your mind to control a robot.

A new study published in the journal ACS Applied Nano Materials took a step toward making this a reality. The team produced “dry” sensors that can record the brain’s electrical activity despite the hair and the bumps and curves of the head by constructing a specific, 3D-patterned structure that does not rely on sticky conductive gels.

The behavior of a collection of squeezed elastic beams is determined by geometry, not by complex forces.

When a collection of thin elastic beams—such as toothbrush bristles or grass—is compressed vertically, the individual elements will buckle and bump into one another, forming patterns. Experiments and numerical simulations now show that basic geometry controls how order emerges in these patterns [1]. The results could be useful for designing flexible materials and for understanding interactions among flexible structures in nature, such as DNA strands in cells.

Studies of bending and buckling have often focused on the behavior of a single membrane, such as a thin disc of polystyrene fabric, a sheet of crumpled paper, or even a bell pepper. But few models have tackled the dynamics of a group of many elastic objects.

2.7 billion light years away, in a galaxy cluster known as Abell 1,201, an ultramassive black hole lurks, measuring upwards of 32.7 billion times the mass of our Sun. This new measurement exceeds astronomers’ previous estimates by at least 7 billion solar masses. It’s one of the biggest black holes astronomers have ever detected and cuts close to how large we believe they can be.

Our universe is filled with black holes, including the supermassive black holes found in the center of galaxies throughout all the regions of space around us. Many of these are inactive, not excreting material that causes them to light up, making them easier to detect. Others are rogue black holes, roaming through space however they please. Others still are ultramassive black holes.

These black holes are much bigger than supermassive black holes like those found at the center of galaxies. And, because they’re so massive – and contain so much mass – they should theoretically be easier to find. However, as I noted above, it all depends on how active the black hole is and how much heat it emits. That’s because, by default, ultramassive black holes (and black holes overall) don’t emit light.
