Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com) Original source AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published 450-million-year-old organism finds new life in Softbotics
(via sciencedaily.com) Original source Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Plants' ingenious defense against mutational damage
(via sciencedaily.com) Original source How do plants deal with mutations in their 'power stations'? By exploiting randomness to create diversity, say researchers.
Published Milestone moment toward development of nuclear clock
(via sciencedaily.com) Original source Physicists have started the countdown on developing a new generation of timepieces capable of shattering records by providing accuracy of up to one second in 300 billion years, or about 22 times the age of the universe.
Published Vacuum in optical cavity can change material's magnetic state without laser excitation
(via sciencedaily.com) Original source Researchers in Germany and the USA have produced the first theoretical demonstration that the magnetic state of an atomically thin material, ?-RuCl3, can be controlled solely by placing it into an optical cavity. Crucially, the cavity vacuum fluctuations alone are sufficient to change the material's magnetic order from a zigzag antiferromagnet into a ferromagnet.
Published Viral impostors: Breakthrough for virus research
(via sciencedaily.com) Original source The penetration of viruses into cells can now be tracked with unprecedented accuracy thanks to an innovative design for pseudoviruses.
Published New secrets about cat evolution revealed
(via sciencedaily.com) Original source By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation.
Published New antibiotic approach proves promising against lyme bacterium
(via sciencedaily.com) Original source Using a technique that has shown promise in targeting cancer tumors, a team has found a way to deploy a molecular warhead that can annihilate the bacterium that causes Lyme disease.
Published Research outlines how sex differences have evolved
(via sciencedaily.com) Original source Researchers have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type level.
Published Female sex determining gene identified in mice
(via sciencedaily.com) Original source Researchers have identified a gene which is an early determining factor of ovary development in mice.
Published A known environmental hazard can change the epigenetics of cells
(via sciencedaily.com) Original source An international team of researchers has discovered that formaldehyde, a widely spread pollutant and common metabolite in our body, interferes in the epigenetic programming of the cell. This finding expands the knowledge of formaldehyde, previously considered only as a DNA mutagen, and helps establishing a further link with cancer.
Published Observation of a virus attaching to another virus
(via sciencedaily.com) Original source 'Satellite' viruses must be in proximity to their 'helper' virus to replicate, but this research reports the first documented case of a satellite virus attaching itself to its helper virus. Out of 50 observed helpers, 40 had a satellite bound. Bioinformatic analysis of the satellite and helper viruses' genomes provides clues as to why the satellite may have evolved to attach to the helper, and suggests this pair may have been co-evolving for about 100 million years.
Published Immunology: Dysfunction of mitochondria drives the exhaustion of T cells
(via sciencedaily.com) Original source In the immune system's fight against cancer and infections, the T cells often lose their power. Now immunologists may have found a possible explanation for this phenomenon.
Published What a '2D' quantum superfluid feels like to the touch
(via sciencedaily.com) Original source Researchers have discovered how superfluid helium 3He would feel if you could put your hand into it. The interface between the exotic world of quantum physics and classical physics of the human experience is one of the major open problems in modern physics. Nobody has been able to answer this question during the 100-year history of quantum physics.
Published Optical-fiber based single-photon light source at room temperature for next-generation quantum processing
(via sciencedaily.com) Original source Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely low temperatures. Now, researchers have developed an ytterbium-doped optical fiber at room temperature. By avoiding the need for expensive cooling solutions, the proposed method offers a cost-effective platform for photonic quantum applications.
Published Researchers engineer colloidal quasicrystals using DNA-modified building blocks
(via sciencedaily.com) Original source A new study unveils a novel methodology to engineer colloidal quasicrystals using DNA-modified building blocks. The implications of this breakthrough are far-reaching, offering a potential blueprint for the controlled synthesis of other complex structures previously considered beyond reach.
Published Bartering light for light: Scientists discover new system to control the chaotic behavior of light
(via sciencedaily.com) Original source Researchers describe a new platform for controlling the chaotic behavior of light by tailoring its scattering patterns using light itself.
Published First mice engineered to survive COVID-19 like young, healthy humans
(via sciencedaily.com) Original source Researchers have genetically engineered the first mice that get a human-like form of COVID-19, according to a new study.
Published Where is a sea star's head? Maybe just about everywhere
(via sciencedaily.com) Original source A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.
Published The ringed seals in Ilulissat Icefjord, Greenland are special
(via sciencedaily.com) Original source Local hunters in the Icefjord near Ilulissat have long known about a special ringed seal -- the Kangia seal -- which is significantly larger and has a markedly different fur color and pattern than typical Arctic ringed seals. Now scientific studies have shown that the Kangia ringed seal has been isolated from other ringed seals for a long period of time -- more than 100,000 years.
