Convergent mechanism of aging discovered
Several different causes of aging have been discovered, but the question remains whether there are common underlying mechanisms that determine aging and lifespan. Researchers from the Max Planck Institute for Biology of Ageing and the CECAD Cluster o.....»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»
Archaeologists found an ancient Egyptian observatory
Expedition leader: "Everything we found shattered our expectations." A few years ago, Egyptian archaeologists discovered what they thought were the ruins of an ancient Egyptian te.....»»
Single-celled eukaryote employs unconventional cytoskeletal components for dynamic shape-shifting
Recently, a research group led by Prof. Miao Wei from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences discovered that Lacrymaria cells utilize unconventional and novel components of the cytoskeleton to achieve their remarkable.....»»
Researchers uncover new plant perception mechanism for light and heat
Researchers at the University of Bayreuth and Heinrich Heine University Düsseldorf have described a previously unknown mechanism in the perception of light and heat in plants. The results contribute to a better understanding of plant physiological p.....»»
Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
Researchers reveal key mechanism in regulating DNA recombination
Meiotic recombination generates genetic diversity and promotes proper chromosomal segregation of parental chromosomes. This process requires a set of recombinases polymerized on single-stranded (ss) DNAs called the nucleoprotein filament to undergo h.....»»
New species of clearwing moth from Guyana discovered in Wales
A new species of moth has been described far away from home following a cross-continent detective journey that included Natural History Museum scientists from separate fields, a budding young ecologist with a knack for community science, a globe-trot.....»»
Researchers determine how a protein contributes to human immune defense against RNA viruses
An international research team led by Prof. Dr. Janosch Hennig from the University of Bayreuth has discovered how the TRIM25 protein contributes to defense against RNA viruses whose genetic material is contained as ribonucleic acid (RNA)......»»
Scientists decode brain mechanisms of stopping in Drosophila
Ever wish you could stop that fruit fly on your kitchen counter in its tracks? Scientists at Max Planck Florida Institute for Neuroscience have created flies that halt under red light. In doing so, they discovered the precise neural mechanisms involv.....»»
Surprising amount and variety of gamma radiation is produced in large tropical thunderstorms, observations reveal
In the 1990s, NASA satellites built to spot high-energy particles coming from supernovas and other celestial-sized objects discovered a surprise—high energy gamma radiation bursts coming from right here on Earth......»»
New super-Neptune exoplanet discovered
An international team of astronomers reports the discovery of a new super-Neptune exoplanet orbiting a solar-type star. The newly detected alien world, which received the designation TOI-5005 b, is about six times larger and more than 30 times more m.....»»
Q&A: Using a new approach to shine a light on hidden plant microbes
Despite there being more microbes on Earth than stars in our galaxy, only a tiny fraction have been discovered. An approach called metagenomics—a type of DNA sequencing—may help scientists learn more about these elusive organisms, according to Pe.....»»
Scientists find plausible geological setting that may have sparked life on Earth
Researchers have discovered a plausible evolutionary setting in which nucleic acids—the fundamental genetic building blocks of life—could enable their own replication, possibly leading to life on Earth......»»
Scientists discover planet orbiting closest single star to our sun
Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered an exoplanet orbiting Barnard's star, the closest single star to our sun. On this newly discovered exoplanet, which has at least half the mass of.....»»
Study elucidates a mechanism for phosphorus cycling in subtropical forests
Phosphorus (P) is an important nutrient element in plant photosynthesis. However, the adsorption of mineral P via leaching and erosion leads to a decrease in P availability and consequently P deficiency......»»
Cities unprepared for impact of climate change, says report
Half of the world's population lives in cities, and that proportion is expected to increase to 70% by 2050. With their large populations, lack of green spaces that can cool a warming environment, and aging infrastructure that is vulnerable to floods.....»»
What should declining Japanese cities do?
Aging societies and population decline have been on the rise globally, but in Japan, the situation has been exacerbated ten-fold. A staggering 36.21 million people, or 28.9% of the populace, are 65 and over. Further, 74.6% of Japan's 1,747 cities are.....»»
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»
Up to 600 million Facebook and Instagram passwords stored in plain text
Meta has been fined €91M ($101M) after it was discovered that to 600 million Facebook and Instagram passwords had been stored in plain text. Some of those passwords had been unprotected since 2012, and were searchable by more than 20,000 Meta em.....»»
