Attention-based deep neural network increases detection capability in sonar systems

In underwater acoustics, deep learning may improve sonar systems to help detect ships and submarines in distress or in restricted waters. However, noise interference can be a challenge. Researchers now explore an attention-based deep neural network to tackle this problem. They tested two ships, comparing their results with a typical deep neural network, and found the ABNN increases its predictions...

Zebrafish could shed light into the mysteries of the human spinal cord and its influence on our body

Researchers believe zebrafish may provide clues to understanding how the human nervous system develops since this fish experiences new movements similarly to how babies do after birth. To understand how our nervous system enables us to move and learn new movements such as walking or swimming as we grow, researchers looked closely at the nervous system of zebrafish and built models of developing...

A 5-sigma standard model anomaly is possible

One of the best chances for proving beyond-the-standard-model physics relies on something called the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The standard model insists that the CKM matrix, which describes the mixing of quarks, should be unitary. But growing evidence suggests that during certain forms of radioactive decay, the unitarity of the CKM matrix might break.

To find sterile neutrinos, think small

Experiments have spotted anomalies hinting at a new type of neutrino, one that would go beyond the standard model of particle physics and perhaps open a portal to the dark sector. But no one has ever directly observed this hypothetical particle.

Some of the biggest asteroids in our Solar System

Astronomers have imaged 42 of the largest objects in the asteroid belt, located between Mars and Jupiter. The observations reveal a wide range of peculiar shapes, from spherical to dog-bone, and are helping astronomers trace the origins of the asteroids in our Solar System.

A computationally quick approach to predict molten droplet solidification on a solid surface

The deposition of molten particles on the interior surface of jet engines can cause significant damage and degrade the performance of the engine. Now, scientists successfully simulated the solidification process of a molten droplet as it impinges on a cooler flat surface. This approach uses a mesh-less method to accurately predict the spread and the solidification of the droplet and could...

Quantum phase transition detected on a global scale deep inside the Earth

A multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth's mantle. Their findings will improve understanding of the Earth's interior, and help elucidate the impact of this phenomenon on tectonic events including volcanic eruptions and earthquakes.

Phage therapy research brings scientists a step closer to harnessing viruses to fight antibiotic resistance

Phage therapy is the concept of using viruses (known as phage) to kill bacteria, instead of using antibiotics. Until now, experiments have largely focussed on exposing bacteria to phage in a flask. Now, researchers have developed a new way to mimic these microenvironments, in which a single bacterium would colonize a specific area. Using this method, the team found that in these microenvironments...

Arctic sea ice may make a last stand in this remote region; it may lose the battle

With warming climate, summer sea ice in the Arctic has been shrinking fast, and now consistently spans less than half the area it did in the early 1980s. This raises the question: It this keeps up, in the future will year-round sea ice -- and the creatures who need it to survive -- persist anywhere? A new study addresses this question, and the results are daunting.

An eco-friendly toxic cocktail could be a new weapon against malaria

Researchers have demonstrated that blood-seeking mosquitoes can be directed to feed on a toxic plant-based solution, which in turn kills them. This result could be one solution for the global problem of diseases like malaria or dengue fever by specifically targeting the mosquitoes while other species like bees won't be affected.
