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 […]
Materials scientists are quite used to looking at nature to find inspiration for new designs and functionalities. The living world is full of complex and sophisticated materials (from bones and seashells to cartilage and skin) that provide the most varied and extraordinary properties and functions. We have paid attention to this strategy of ‘architecturing materials’ […]
Hint of our solar system’s future observed A planet the size of Jupiter circling a deceased white dwarf star about 6,500 light-years from Earth is offering a glimpse of what may happen when the sun burns out roughly 5 billion years from now. Researchers were surprised to discover that the gas giant survived its sun-like […]
The capacity of creating an electronic bonding network between localized units would be key to enhance the critical temperature in hydrogen-based superconductors, according to recent results. The field of hydrogen-based superconductivity has progressed enormously since 1968, when Ashcroft first proposed that pressurized hydrogen may become a high-temperature superconductor due to the high energy of its […]
