New technique zeros in on the genes that snakes use to produce venom
Only about 10% of the world's roughly 4,000 snake species have venom strong enough to seriously hurt a human, but that's enough for snake bites to be an important public health concern. To help better understand how snakes make their venom and how ve.....»»
Observing gain-induced group delay between multiphoton pulses generated in a spontaneous down-conversion source
Spontaneous parametric down-conversion (SPDC) and spontaneous four-wave mixing are powerful nonlinear optical processes that can produce multi-photon beams of light with unique quantum properties. These processes could be leveraged to create various.....»»
Lizards and snakes are 35 million years older than we thought
Reanalysis of a fossil finds that reptiles' traits go back earlier than we thought. Lizards are ancient creatures. They were around before the dinosaurs and persisted long after d.....»»
Less is more: Why an economical iridium catalyst works so well
Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the iridium, is as efficient and stable over time as the best commer.....»»
M4 Mac mini was almost even smaller, but design compromises were made
The redesign of the M4 Mac mini could've been even smaller, Apple executives have admitted, but there were quite a few tradeoffs needed to produce the best version yet.The M4 Mac mini [middle] between an older Mac mini [below] and an Apple TV [above].....»»
Mechanical engineer figures out way to enhance sensitivity of nanopores for early detection of diseases
SMU Lyle mechanical engineering graduate student Kamruzzaman Joty has introduced a new technique in nanotechnology for detecting and analyzing biomolecules, potentially paving the way for new methods of early disease detection......»»
Hybrid statistical technique for predicting extreme weather events in South Florida
An innovative technique for predicting extreme weather events in South Florida has emerged from researchers at the FAMU-FSU College of Engineering. The innovation specifically addresses the challenges of forecasting extreme heat and heavy rainfall......»»
Scientists develop ultrasound-based technique as a tool for directing cell growth and orientation
Developing reliable methods to replace dead or damaged tissue is one of the primary goals of regenerative medicine. With steady advances in tissue engineering and biomedicine, scientists are almost at a point where growing cell sheets in the lab and.....»»
The Amazon rainforest as a cloud machine: How thunderstorms and plant transpiration produce condensation nuclei
The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when exposed to light conditions. The CAFE-Brazil measu.....»»
Dynamic tracking technique can reduce noise in gravitational-wave detectors to peer deeper into the cosmos
Researchers have shown that optical spring tracking is a promising way to improve the signal clarity of gravitational-wave detectors. The advance could one day allow scientists to see farther into the universe and provide more information about how b.....»»
Discovery of molecular switch explains how bacteria control their protein biosynthesis through cell metabolism
Protein biosynthesis—the process whereby cells produce protein molecules, which are essential for life and growth—is a highly complex and strictly regulated affair. An interdisciplinary team led by LMU biologist PD Dr. Jürgen Lassak has now disc.....»»
Peat-bog fungi produce substances that kill tuberculosis-causing bacteria
An analysis of fungi collected from peat bogs has identified several species that produce substances toxic to the bacterium that causes the human disease tuberculosis. The findings suggest that one promising direction for development of better treatm.....»»
Backyard chickens in Australia perceived as companion animals and food source, interviews reveal
Chickens have been a mainstay in Australian backyards for generations. New research from the University of Adelaide reveals that owners see their chooks as a blend between pet and livestock as well as a trustworthy source of produce......»»
New laser technique achieves atomic-scale precision on diamond surfaces
Imagine placing an object under a microscope and pressing a button to rearrange the surface atoms with atomic-scale precision. This once sci-fi scenario is now a reality thanks to pioneering research published in Applied Surface Science......»»
AI-enhanced satellite carbon monoxide fast retrieval
A recent study presents a radiative transfer model-driven machine learning technique for retrieving carbon monoxide from the world's first hyperspectral Geostationary Interferometric Infrared Sounder (GIIRS) onboard Fengyun-4B (FY-4B) satellite, prov.....»»
Enterococcus helps E. coli "armor up" in dog and poultry co-infections
A new study finds that two subtypes of pathogenic Escherichia coli (E. coli) produce five to 16 times more protective capsular "slime" when Enterococcus faecalis (EF) is present. The finding could lead to targeted therapies for E. coli infections spe.....»»
Higher-density storage technique could allow diamond disk to store equivalent of 2,000 Blu-ray discs
A team of engineers at the University of Science and Technology of China has developed a new way to code data onto a diamond with higher density than prior methods. In their paper published in the journal Nature Photonics, the group notes that such o.....»»
Artificial intelligence finds previously undetected historical climate extremes
There are over 30,000 weather stations in the world, measuring temperature, precipitation and other indicators often on a daily basis. That's a massive amount of data for climate researchers to compile and analyze to produce the monthly and annual gl.....»»
Researchers find a possible solution to the cosmic ray muon puzzle
Scientists have a problem with cosmic rays—they produce too many muons at the Earth's surface. Cascades of muons are byproducts of high-energy cosmic rays as they collide with nuclei in the upper atmosphere, and scientists see more muons at Earth's.....»»
Northern lights may be faintly visible across parts of the US this Thanksgiving
This Thanksgiving, solar storms may produce faint auroras across the northern rim of the United States......»»
Study discovers how algae produce a hormone they use to communicate
A study at the University of Cordoba shows how algae produce auxin, a plant hormone, opening a path of communication with bacteria to generate synergies that could benefit agricultural production. The paper is published in the journal iScience......»»
