Organic molecules detected in Curiosity collection A soil sample collected by the Curiosity rover at Bagnold Dune contained organic molecules, the first ever detected on Mars. Instead of dropping the sample into an empty cup, scientists decided to put the sample into a cup prepped with a chemical reagent, which revealed organic molecules not detected […]
Topological materials have special universal properties, which are protected against perturbations. The name comes from the fact that such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. Topological materials behave like an ordinary insulator in the bulk but have conducting […]
That collective decisions made through voting may lead to some weird consequences is something probably well known since the first time one tribe started to use some kind of voting in order to reach an agreement. Contrarily to what happens in many other areas of human wisdom, we don’t have any deep reflections on the […]
New look at fossils puts bryozoans in Cambrian Explosion Researchers reexamined ancient fossils with new technology to find that bryozoans, filter-feeding creatures that live in water like corals, were present during the Cambrian Explosion and describe their findings in Nature. The fossil, which is shaped like a honeycomb, was revealed in finer detail using micro-computed […]
Microscopy is a leading technology in biological research. Today, a typical microscopy session may generate hundreds to thousands of images, generally requiring computational analysis to extract meaningful results. But a simple analysis is not enough any more. Over the last few years, deep learning (DL) has increasingly become one of the gold standards for high-performance […]
We live in a world in which momentous decisions are made by people often without forethought. But some things are predictable, including that if you continually consume a finite resource without recycling, it will eventually run out. Yet, as we set our sights on embarking back to the moon, we will be bringing with us […]
It happens often. We see someone who reminds us of someone else we know, or we have met, but we cannot remember where, only the face is familiar. Whether there was a single cell in the brain responsible for familiar face recognition was a long-standing question in neuroscience. Now, it seems that those cells, which […]
Genetically edited pig kidney transplanted into patient The genetically altered kidney of a pig was transplanted into a brain-dead patient exhibiting signs of kidney dysfunction at New York University Langone Health with the consent of the patient’s family. The genes of the pig were edited to remove a molecule that can trigger immediate rejection. Reuters […]
Because of their unique physical properties, nanomaterials have intrinsic advantages as biosensors and actuators, and they may be applicable to humans without the need for genetic modifications. It follows, then, that nanoscience could make major methodological contributions to the future of biomedical sciences, especially neuroscience. Meet NanoNeuro , a new field defined as the intersection […]
The San Pedro River winds from rainforests in Guatemala through the Yucatan Peninsula in eastern Mexico. There, this peaceful river widens into a series of slow-flowing lakes. Along a remote 50-mile (80-kilometer) stretch, thousands of red mangroves – trees commonly found along tropical coastlines – line the river’s banks and gentle waterfalls. Unlike mangroves elsewhere […]
