Smallest-Ever Human-Made Flying Structure Is a Winged Microchip, Scientists Say
An anonymous reader quotes a report from NPR: It's neither a bird nor a plane, but a winged microchip as small as a grain of sand that can be carried by the wind as it monitors such things as pollution levels or the spread of airborne diseases. The t.....»»

Multi-scale, nanomaterial-based ice inhibition platform enables full-cycle cryogenic protection for mouse oocytes
Safe and high-quality fertility preservation is of growing significance for women in clinical trials. Current primary methods for cryopreserving human oocytes are slow freezing and vitrification, but existing techniques pose risks of biochemical toxi.....»»
A thousand times smaller than a grain of sand—glass sensors 3D-printed on optical fiber
In a first for communications, researchers in Sweden 3D printed silica glass micro-optics on the tips of optic fibers—surfaces as small as the cross section of a human hair. The advance could enable faster internet and improved connectivity, as wel.....»»
Sweltering heat across Asia was 45 times more likely because of climate change, study finds
Sizzling heat across Asia and the Middle East in late April that echoed last year's destructive swelter was made 45 times more likely in some parts of the continent because of human-caused climate change, a study Tuesday found......»»
Scientists raise minimum magnetic field of a single measurement to sub-femtotesla level
A research team has, for the first time, realized the quantum amplification of an extremely weak magnetic field by using dark spin, with the magnetic field magnification exceeding a factor of 5,000 and the single magnetic field measurement accuracy r.....»»
Scientists achieve giant Rashba–Dresselhaus spin splitting in 2D chiral metal-organic frameworks
A research team led by Prof. Li Xingxing and academician Yang Jinlong from University of Science and Technology of China (USTC) has developed two-dimensional (2D) chiral metal-organic frameworks as Rashba-Dresselhaus (R-D) semiconductors with large s.....»»
Tiger beetles fight off bat attacks with ultrasonic mimicry
Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat echolocation. To date, scientists have found at leas.....»»
How pooling solutions can be strengthened in road transport
Less than a hundred kilos of human weight, more than two metric tons of steel: individual road transport is a huge climate killer, and switching to electric vehicles is only part of the solution because manufacturing the vehicles also causes emission.....»»
Exploring interface phenomena for more durable and effective nickel–tungsten alloys
Alloying is a key process in creating new materials. By combining metals with desirable traits, scientists can produce alloys with suitable properties. For example, stainless steel, formed by combining iron with chromium, nickel, and other elements i.....»»
Chemists succeed in synthesizing a molecule first predicted 20 years ago
The first and the best-known metallocene is "ferrocene," which contains a single iron atom. Today, sandwich complexes can be found in many inorganic chemistry textbooks, and the bonding and electronic structure of metallocenes is taught in undergradu.....»»
Scientists develop an affordable sensor for lead contamination
Engineers at MIT, Nanytang Technological University, and several companies have developed a compact and inexpensive technology for detecting and measuring lead concentrations in water, potentially enabling a significant advance in tackling this persi.....»»
Reducing distrust in social media is not straightforward, computer scientists warn
Are anti-misinformation interventions on social media working as intended? It depends, according to a new study led by William & Mary researchers and published in the Proceedings of the CHI Conference on Human Factors in Computing Systems (CHI '24)......»»
New candidate genes for human male infertility found by analyzing gorillas" unusual reproductive system
Despite their formidable bodies, male gorillas are lacking in one particular area of their anatomy......»»
Scientists unlock mysteries of orangutan communication
In a study published in PeerJ, scientists have revealed the intricate vocal patterns of Bornean orangutans, shedding new light on the complexities of their communication. Titled "Vocal Complexity in the Long Calls of Bornean Orangutans," the research.....»»
Uneven strain distribution induces detwinning in penta-twinned nanoparticles
Twinned nanoparticles have regions of clear symmetry that share the same crystal lattice, separated by a clear boundary. Changing the twin structure can affect the properties of the nanoparticles, which makes controlling twinning to create tailored n.....»»
Study discovers distinct population of "troublemaker" platelet cells appear with aging
As people age, they become more prone to blood clotting diseases, when blood cells called platelets clump together when they don't need to and can cause major issues such as strokes and cardiovascular disease. For decades, scientists have studied why.....»»
Using AI to speed up and improve the most computationally-intensive aspects of plasma physics in fusion
The intricate dance of atoms fusing and releasing energy has fascinated scientists for decades. Now, human ingenuity and artificial intelligence are coming together at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) t.....»»
