How a molecular machine is assembled to convert light to food for plants
The conversion of light into chemical energy by plants and photosynthetic microorganisms is one of the most important processes in nature, removing climate-damaging CO2 from the atmosphere. Protein complexes, so-called photosystems, play the key role.....»»
Gamma radiation converts methane into complex organic molecules and could explain the origin of life
Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, according to a new article published in the journal Angewandte Chemie International Edition.....»»
Genetic repair via CRISPR can inadvertently introduce other defects, researchers show
The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to correct specific defective sections of the genome. Unfortunately, however, there is a catch: under certain condit.....»»
Bioinspired hydrogels harness sunlight: A step closer to artificial photosynthesis
Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature's method, using sunlight to drive chemical react.....»»
Asteroid grains shed light on the outer solar system"s origins
Tiny grains from a distant asteroid are revealing clues to the magnetic forces that shaped the far reaches of the solar system more than 4.6 billion years ago......»»
New research may lead to potatoes that are less reliant on nitrogen fertilizers
Because nitrogen fertilizers contribute to global greenhouse gas emissions, scientists are looking for ways to modify agricultural plants so that they rely on less nitrogen. In research published in New Phytologist, investigators have found that bloc.....»»
Scientists shed light on an arms race between barley and a fungal pathogen
Scientists from the Leibniz Institute of Plant Biochemistry (IPB), together with partners from the University of Cologne, have discovered a new group of defense substances in barley that are effective against a broad spectrum of fungal pathogens. One.....»»
Survey highlights "publish or perish" culture as key factor in research irreproducibility
An international survey involving over 1,600 biomedical researchers has shed light on the perceived causes of irreproducibility in research results. The survey, which included participants from various countries and research institutions, aimed to id.....»»

Spraying rice with zinc oxide nanoparticles protects yields during heat waves, study finds
A small team of horticulturists in China and the U.S. has found that spraying rice plants with a zinc oxide nanoparticle solution helps them better handle the stress of a heat wave. In their study, published in Proceedings of the National Academy of.....»»
A single atom can change the directional profile of the light emitted in scanning tunneling microscopes
Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM.....»»
Beware of phishing emails delivering backdoored Linux VMs!
Unknown attackers are trying to trick Windows users into spinning up a custom Linux virtual machine (VM) with a pre-configured backdoor, Securonix researchers have discovered. The campaign The attack began with a phishing email, they believe, but the.....»»
Scientists discover all-optical nuclear magnetic resonance analog with quantum fluids of light
Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which emits a linearly polarized light with a polarization a.....»»
Drugmaker shut down after black schmutz found in injectable weight-loss drug
The warning comes amid a legal war over compounded weight-loss drugs. The Food and Drug Administration is warning consumers not to use any drugs made by a compounding pharmacy in.....»»
Svalbard Global Seed Vault evokes epic imagery and controversy because of the symbolic value of seeds
Two-thirds of the world's food comes today from just nine plants: sugar cane, maize (corn), rice, wheat, potatoes, soybeans, oil-palm fruit, sugar beet and cassava. In the past, farmers grew tens of thousands of crop varieties around the world. This.....»»
Genome sequencing of all four Macadamia species unlocks new potential for crop improvement
A research team has successfully sequenced and assembled the genomes of all four Macadamia species, marking a significant advance in crop improvement efforts for this commercially valuable nut. The findings reveal key genetic traits that could enhanc.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Organosilicon chemistry offers options for replacing PFAS in food and medical industries
Due to the unique properties of PFAS, almost no other chemical substances can compete with them. That explains why it is so hard to find a replacement for these toxic "forever chemicals," which accumulate in the environment and do not break down over.....»»
Study reveals effect of slope position on nonstructural carbohydrates in biological soil crusts
Nonstructural carbohydrates (NSCs) provide energy for metabolic processes in plants and play a key role in plant growth, defense and osmoregulation. However, the regulation of NSC in biological soil crusts across different slope positions remains unc.....»»
