Discovery of a tRNA modification enzyme that also acts on nucleosides
The genetic information on DNA is transcribed into messenger RNA (mRNA) and translated to the amino acid sequence by transfer RNA (tRNA) on the ribosome. Modified nucleosides within RNA are involved in maintaining and regulating the protein synthesis.....»»
Tellurium nanowires show potential for room-temperature ferroelectricity and data storage
A discovery by an international team of scientists has revealed room-temperature ferroelectric and resistive switching behaviors in single-element tellurium (Te) nanowires, paving the way for advancements in ultrahigh-density data storage and neuromo.....»»
Biochemists uncover a new enzyme subclass in antimicrobial lanthipeptide biosynthesis
Biochemists from the National University of Singapore (NUS) have discovered a new subclass of trifunctional enzymes in gram-positive bacteria, which play a critical role in the biosynthesis of an antimicrobial lanthipeptide......»»
The Whole Story of How Humans Evolved From Great Apes
The picture of human evolution has changed repeatedly and dramatically over the past half century, shaped by waves of new fossil discovery, technology, and scientific techniques......»»
Why did Louis de Broglie, Nobel laureate in physics, abandon his own pilot wave theory?
This week marks the centenary of the French physicist Louis de Broglie's doctoral thesis, which later earned him a Nobel prize for "his discovery of the wave nature of electrons." This discovery constitutes a central aspect of quantum mechanics, and.....»»
Life found on Ryugu asteroid sample, but it’s not as exciting as it sounds
A recent discovery made by scientists working with a sample of rock from outer space highlights one of the huge challenges that such work involves......»»
Passport control for glycan maturation: Discovery of a molecular tag that enhances biopharmaceutical quality
A collaborative research group, including researchers from Nagoya City University, National Institutes of Natural Sciences, and RIKEN has uncovered a molecular tool, the "passport sequence," that significantly improves the production efficiency and q.....»»
Maritime pine seeds remember temperature conditions
The seeds of maritime pines remember the temperatures they experienced during early development. This memory persists in young trees for at least two years after germination. The above discovery was made by researchers at INRAE, CEA, FCBA, the Univer.....»»
Ultrawide binary objects in the Kuiper belt may not have come from the earliest solar system, research suggests
Trying to understand the makeup and evolution of the solar system's Kuiper belt has kept researchers busy since it was hypothesized soon after the discovery of Pluto in 1930. In particular, binary pairs of objects there are useful as indicators since.....»»
New mechanism in bacterial DNA enzyme opens pathways for antibiotic development
Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Center have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic target. This enzyme, present in bacteria but absent i.....»»
Researchers claim Tutankhamun"s burial mask may have been made for a woman—but there is reason to doubt
Since the discovery of Tutankhamun's tomb in the Valley of the Kings in Egypt over 100 years ago, the contents have been examined countless times. But new details continue to surprise archaeologists......»»
On the trail of an 18th-century master forger: New evidence discovered
A document held in Göttingen University's Faculty of Humanities has been revealed as an 18th century forgery. The document purports to be from 1266, but mentions a church in Pisa that was not built until later. This discovery is the result of resear.....»»
Niagara fireball event leads to discovery of tiniest known asteroid
In an international study led by Western University and Lowell Observatory, scientists describe a pioneering, integrative approach for studying near-Earth asteroids based largely on a November 2022 fireball event that dropped meteorites in the Niagar.....»»
Fossil discovery reveals giant worm lizard with snail-cracking jaws
An international team of researchers has discovered a new fossil worm lizard species in Tunisia. Terastiodontosaurus marcelosanchezi is the largest known species of the Amphisbaenia group, with a skull length of over five centimeters......»»
Discovery of van Hove singularities could lead to novel materials with desirable quantum properties
Strong interactions between subatomic particles like electrons occur when they are at a specific energy level known as the van Hove singularity. These interactions give rise to unusual properties in quantum materials, such as superconductivity at hig.....»»
Ryugu asteroid sample rapidly colonized by terrestrial life despite strict contamination control
Panspermia is the hypothesis that life can survive the transfer between planetary bodies as a secondary path for life to get started on planets throughout a solar system. The discovery of extraterrestrial life on asteroids or within meteorites would.....»»
Origin of life research finds RNA can favor both left- and right-handed proteins
The mystery of why life uses molecules with specific orientations has deepened with a discovery that RNA—a key molecule thought to have potentially held the instructions for life before DNA emerged—can favor making the building blocks of proteins.....»»
Establishing a general theory of metal-support interaction: AI-driven advances in catalysis
How can artificial intelligence (AI) help accelerate scientific discovery based on vast amounts of experimental data? A new study by Prof. Li Weixue's team from the University of Science and Technology of China (USTC) of the Chinese Academy of Scienc.....»»
Researchers identify previously unknown compound in drinking water
A team of researchers from the United States and Switzerland has reported the discovery of a previously unknown compound in chloraminated drinking water. Inorganic chloramines are commonly used to disinfect drinking water to safeguard public health f.....»»
Young planet discovery could provide new insight into planet formation
