In a new experimental study, researchers looked to the natural strength of lobster shells to design special 3D printing patterns. Their bio-mimicking spiral patterns improved the overall durability of the 3D printed concrete, as well as enabling the strength to be precisely directed for structural support where needed.

Researchers have developed a way of combining a bone substitute and drugs to regenerate bone and heal severe fractures in the thigh or shin bone. The study was conducted on rats, but the researchers think that the method in various combinations will soon be commonplace in clinical settings.

Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in a new research. This first look at relatively small features, dubbed “plumelets,” could help scientists understand how and why disturbances form in the solar wind.

A team of researchers has discovered a form of the famous particle within a superconductor, a material capable of conducting electricity without resistance, generally at very cold temperatures. They write that in lab experiments they’ve found a short-lived “Higgs mode” within iron-based, high-temperature (but still very cold), multi-energy band, unconventional superconductors.

Researchers have found a way to make ‘green’ ammonia from air, water and renewable electricity that does not require the high temperatures, high pressure and huge infrastructure currently needed to produce this essential compound. The new production method also has the potential to play a role in the global transition towards a hydrogen economy, where ammonia is increasingly seen as a solution to the problem of storing and transporting hydrogen energy.

Researchers have used lasers to create miniature robots from bubbles that lift, drop, and manipulate small pieces into interconnected structures. The researchers created microbubbles in water by focusing a laser underneath a small part made of resin. The bubble’s size was controlled by rapidly switching the laser on and off, with a higher amount of time in the “on position” resulting in larger bubbles.

Scientists have developed a pioneering new technique that could revolutionise the accuracy, precision, and clarity of super-resolution imaging systems. The new technique, called Repeat DNA-Paint, is capable of suppressing background noise and nonspecific signals, as well as decreasing the time taken for the sampling process.

Researches have a method called robomorphic computing that uses a robot’s physical layout and intended applications to generate a customized computer chip that minimizes the robot’s response time. The advance could fuel a variety of robotics applications, including, potentially, frontline medical care of contagious patients.

Physicists have searched for axions in Betelgeuse, a nearby star that is expected to burn out as a supernova soon, at least on astrophysical timescales. However, when the team looked for expected signatures of axions, in the form of photons in the X-ray band, their search came up empty. Their results rule out the existence of ultralight axions that can interact with photons over a wide range of energies.

Astronomers have detected the first Jupiter-like planet without clouds or haze in its observable atmosphere. Named WASP-62b, the gas giant was first detected in 2012 through the Wide Angle Search for Planets (WASP) South survey. Its atmosphere, however, had never been closely studied until now.
