Astronomers have detected an enormous extragalactic structure hiding in an uncharted region of space far beyond the Milky Way ‘s center.

This phantom region, known as the zone of avoidance, is a blank spot on our map of the universe, comprising somewhere between 10% and 20% of the night sky. The reason we can’t see it — at least with standard visible light telescopes — is because the Milky Way’s bulging center blocks our view of it; the center of our galaxy is so dense with stars, dust and other matter that light from the zone of avoidance gets scattered or absorbed before reaching Earth’s telescopes.

However, researchers have had better luck uncovering the zone’s secrets with telescopes that can detect infrared radiation — a type of energy that’s invisible to human eyes, but powerful enough to shine through dense clouds of gas and dust. Infrared surveys of the zone of avoidance have found evidence of thousands of individual galaxies shining through the cosmic fog, though little is known about the large-scale structures that lurk there.

Could energy efficiency be quantum computers’ greatest strength yet?

Iran’s priority in entering the Ukrainian war arena was to test NATO’s defenses against its drones, to assess the strength of these defenses in the face of Iranian offensive capabilities. It can be said that in the initial stages, the Shahed-136 drone actually managed to achieve exceptional success against NATO air defense employed by the Ukrainian army. This marks a victory for Tehran.

However, the ultimate evaluation of the Shahed-136 drone’s capability against NATO defenses will have to wait until NATO supplies Ukraine with more air defenses in the days ahead. The implications of these advances for the balance of power between Russian and Ukrainian forces, as well as the reputation of the types of weapons supplied to the Ukrainian military, were certainly realized by NATO’s leadership in the wake of these drone attacks. NATO swiftly rushed to implement additional air defense systems designed to deal with such small, drones that are capable of flying at low altitudes.

A tribute to the Garden City (Bengaluru), a ‘Walk in The Garden’ experience is designed to take passengers through green walls, hanging gardens, and outdoor gardens.

A new study at Monash University illustrates how substrates affect strong electronic interactions in two-dimensional metal-organic frameworks.

Materials with strong electronic interactions can have applications in energy-efficient electronics. When these materials are placed on a substrate, their electronic properties are changed by charge transfer, strain, and hybridization.

The study also shows that electric fields and applied strain could be used to “switch” interacting phases such as magnetism on and off, allowing potential applications in future energy-efficient electronics.

The UK @Ministry of Defence #Defence Science and #Technology Laboratory (Dstl) has hosted the UK’s first high-powered, long-range #Laser Directed Energy Weapon (LDEW) trial on its ranges at Porton Down.

The trials involve firing the UK #DragonFire demonstrator at a number of targets over a number of ranges, demanding pinpoint accuracy from the beam director.

In a new study published in the journal PLOS Biology, a team of researchers at University College London posit that it became the “universal currency of life” by way of a little thing known as phosphorylation.

Basically, phosphorylation is the process by which ATP is created. A phosphate molecule is added to another chemical called ADP, and voíla: ATP is born. That same phosphate, as ScienceAlert explains, is then used for another process called hydrolysis, or the reaction of an organic chemical with water that breaks down ATP for use — and that connection with water may be where the secret to ATP’s metabolic dominance lies.

Well, partly. As the scientists discovered in their research, ATP couldn’t rise to the top alone. It needed both water and another phosphorylating molecule, called AcP, to do it. And in fact, it’s likely that ATP actually knocked out AcP as top energy-giving dog.

The new method for harnessing the power of the Sun is “cheaper than traditional fusion approaches.”

U.K.-based startup First Light Fusion is developing its prototype Big Friendly Gun (BFG) in a bid to achieve nuclear fusion without relying on lasers and powerful magnets.

To convert heat into electricity, easily accessible materials from harmless raw materials open up new perspectives in the development of safe and inexpensive so-called “thermoelectric materials.” A synthetic copper mineral acquires a complex structure and microstructure through simple changes in its composition, thereby laying the foundation for the desired properties, according to a study published in the journal Angewandte Chemie.

The novel synthetic material is composed of copper, manganese, germanium, and sulfur, and it is produced in a rather simple process, explains materials scientist Emmanuel Guilmeau, CNRS researcher at CRISMAT laboratory, Caen, France, who is the corresponding author of the study. “The powders are simply mechanically alloyed by ball-milling to form a precrystallized phase, which is then densified by 600 degrees Celsius. This process can be easily scaled up,” he says.

Thermoelectric materials convert heat to electricity. This is especially useful in industrial processes where waste heat is reused as valuable electric power. The converse approach is the cooling of electronic parts, for example, in smartphones or cars. Materials used in this kind of applications have to be not only efficient, but also inexpensive and, above all, safe for health.
