Why eukaryotes, not bacteria, evolved complex multicellularity
Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around 1–1.5 billion years la.....»»
Digital quantum simulation of nuclear magnetic resonance experiments
Programmable quantum computers have the potential to efficiently simulate increasingly complex molecular structures, electronic structures, chemical reactions, and quantum mechanical states in chemistry that classical computers cannot. As the molecul.....»»
Calcium transport protein in bacteria offers insights for drug development and food safety
Researchers at Umeå University have revealed details on how bacteria use calcium to regulate vital processes in a way that differs from human cells. This breakthrough is significant in the fight against antibiotic resistance and for increasing safet.....»»
Carbon capture has a place in Illinois" climate-change toolkit
Approaching downstate Decatur by car, it's not unusual to smell the huge Archer Daniels Midland industrial complex before seeing it. The sweet aroma of fermenting grain wafts through vehicle windows and air vents, a sign that ethanol fuel is being br.....»»
Mountain chickadees songs provide real-time evidence for Darwin"s character displacement theory
Mountain chickadees in Boulder have evolved a different tune to avoid getting mixed up with their cousins, according to a new CU Boulder-led study published Oct. 9 in the Journal of Evolutionary Biology......»»
Evolution in real time: Scientists predict—and witness—evolution in a 30-year marine snail experiment
Snails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought in a distinct population of the same snail species.....»»
Chinese software is a threat, but hardware will be the ban"s compliance challenge
Even as the federal government attempts to minimize threats from China, American manufacturers rely on a complex web of suppliers, including Chinese companies......»»
Scientists discover how innate immunity envelops bacteria
The protein GBP1 is a vital component of our body's natural defense against pathogens. This substance fights against bacteria and parasites by enveloping them in a protein coat, but how the substance manages to do this has remained unknown until now......»»
New analysis tools can help farmers make informed choice on "agrivoltaics"
The dual use of land for agriculture and solar energy production, known as agrivoltaics, presents a new opportunity for farmers, but whether it makes economic sense for growers is a complex question. A new set of analytical tools developed by researc.....»»
Targeting "selfish" bacteria could optimize inhibitors that fight antibiotic resistance
As strains of pathogens resistant to frontline antibiotics become more common worldwide, clinicians are more often turning to combination treatments that degrade this resistance as a first treatment option......»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
Hendrick, Speedway Motorsports unveil exclusive driving club complex in North Carolina
Former Formula One driver Alex Wurz designed the lighted, 1.7-mile driving course......»»
Spectroscopy study determines how catalysts remove dangerous nitrogen oxides
Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual.....»»
Yes, nature is complex—but saving our precious environment means finding ways to measure it
Nature loss directly threatens half the global economy. The rapid destruction of biodiversity should alarm the many Australian businesses dependent on nature, such as those in agriculture, tourism, construction and food manufacturing. Yet nature cons.....»»
Barnacle-inspired polymers could present new way to design antibiotics, researchers say
Scientific literature has shown that barnacles that cling to rocks at the seashore use naturally occurring chemicals to clear rock surfaces of bacteria in preparation for laying down their sticky "glue." Since bioengineering professor Abraham Joy's l.....»»
Cosmic-ray neutron rover assists in estimating mesoscale soil moisture on eastern Qinghai-Tibetan plateau
Soil water resources are crucial for hydrological processes and ecosystem functions on the Qinghai-Tibetan Plateau. However, accurately measuring soil moisture distribution in this region is challenging due to diverse ecosystems, complex terrain, and.....»»
Researchers find dragonfly species with darker wings have evolved to withstand heat and attract partners
Temperature determines where species can live and if they are threatened by a warming climate. So, for a long time, biologists studied how heat tolerance affects survival. Yet, less is known about how thermal traits influence reproduction, which is d.....»»
Team uncovers the complex social life of rats, with potential implications for human psychiatry
The social behaviors of the Rattus norvegicus, commonly known as the Norway rat, are far more complex than previously thought, according to a team of researchers from ELTE Eötvös Loránd University......»»
How Chlamydia pneumoniae bacteria use molecular mimicry to manipulate the host cell
Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. A team of biologists from Heinrich Heine University Düsseldorf (HHU), together with medical professionals and exper.....»»
Paying out disaster relief before climate catastrophe strikes
Beyond the complex byways of international finance, a simple solution is gaining ground to protect populations caught in the path of destructive extreme weather: transfer a little money via their mobile phones before disaster strikes......»»
Research team develops metallodrug-antibiotic combination strategy to combat superbugs
Antimicrobial resistance (AMR) bacterial infections have become a serious problem threatening human health worldwide. The overuse of antibiotics has promoted drug-resistant mutations in bacteria, causing almost all clinically used antibiotics to deve.....»»
