Five common English words we don't know the origins of—including 'boy' and 'dog'
The naming process, the act of naming the items of the world, is as old as the first words spoken by our ancestors. We can reconstruct the stages of this process through etymology, which studies the historical development of the lexicon of a language.
With its latest moon mission success, China's space program has the US in its sights
June 25 2024 marked a new "first" in the history of spaceflight. China's robotic Chang'e 6 spacecraft delivered samples of rock back to Earth from a huge feature on the moon called the south pole–Aitken basin. After touching down on the moon's "far side," on the southern rim of
New catalysts enable greener ester synthesis
A new catalyst may well catalyze a shift to greener chemistry. Chemists from Yokohama National University have successfully developed innovative catalysts containing two noble metals that demonstrate remarkable efficiency in ester-producing chemical reactions and utilize oxygen
Ancient volcanic eruption not a catalyst for early Homo sapiens cultural innovations, researchers say
An international team of researchers from the Universities of Tübingen (Dr. Armando Falcucci), Siena, and Bologna analyzed the cultural remains left by groups of early Homo sapiens at Grotta di Castelcivita in southern Italy, dating back to before the major eruption known as
Motivated to disagree: What can be learned about rapid polarization from the Israeli judicial reform?
A recent study, conducted in the midst of last year's widespread protests in Israel, has uncovered extreme polarization in public opinion regarding the judicial reform introduced by Prime Minister Benjamin Netanyahu's government.
Researchers explain the imaging mechanisms of atomic force microscopy in 3D
Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University report the 3D imaging of a suspended nanostructure. The technique used is an extension of atomic force microscopy and is a promising approach for visualizing various 3D biological systems.
Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly, causing an ultrafast
Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as work on complex materials,
Study finds ways to enhance transcription factor activity
Transcription factors regulate gene expression by binding specific sequences on DNA, which is an essential step to producing messenger RNAs from protein-coding genes. Denes Hnisz's lab, in collaboration with Martin Vingron's lab at the MPIMG, has discovered that human
Study reveals human degradation of tropical forests is greater than previously estimated
Tropical forests are essential to sustain high biodiversity and mitigate climate change. They suffer from deforestation, the cutting and converting of forests for agriculture, mining, or infrastructure purposes. However, significant human impacts on the remaining forests that
Investigations of the polysomatism of antigorite under pressure
Antigorite is a type of serpentine, which is the most abundant hydrated mineral on the Earth. It is widely believed that this mineral is the main carrier of water deep into the Earth in subducting oceanic plates. It has a wavy structure along the a-axis, and in nature, several
AI-assisted technology detects nanoplastics in water—instantly
A McGill-led research team has developed the first real-time, on-site technology capable of detecting and deciphering nanoplastics from all other particles in water, a capacity akin to being able to find a needle in a haystack within milliseconds.
Novel 2D device for quantum cooling converts heat to voltage at ultra-low temperatures
EPFL engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, which require extremely
Elusive temporary star described in historical documents recreated using new computer model
A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary "guest star," now labeled supernova (SN) 1181, which was recorded in historical documents in Japan and elsewhere in
Scientists uncover conserved mechanism of pericentric heterochromatin initiation in vertebrates
A study published in Nature on July 4 by Prof. Zhu Bing from the Institute of Biophysics of the Chinese Academy of Sciences has shed light on the conserved mechanism responsible for the initiation of pericentric heterochromatin in vertebrates.
AI approach optimizes development of antibody drugs
Proteins have evolved to excel at everything from contracting muscles to digesting food to recognizing viruses. To engineer better proteins, including antibodies, scientists often iteratively mutate the amino acids—the units that are arranged in a sequence to make up
New chemical process separates textile fibers for easier recycling
A combined team of chemical and biomolecular engineers from the University of Delaware, and the Center for Plastics Innovation, both in the U.S., has developed a way to chemically separate fibers in textiles, allowing them to be recycled more quickly and cheaply than
'Vaults' within germ cells offer more than safekeeping
Maternal messenger RNAs (mRNAs), located within the cytoplasm of an immature egg, are crucial for jump starting development. Following fertilization, these mRNAs are passed onto the zygote, the first newly formed cell.
Scientists visualize magnetic fields at atomic scale with holography electron microscope
A research team from Japan, including scientists from Hitachi, Ltd. (TSE 6501, Hitachi), Kyushu University, RIKEN, and HREM Research Inc. (HREM), has achieved a major breakthrough in the observation of magnetic fields at unimaginably small scales.
Offshore windfarms: A threat for electro-sensitive sharks?
An ongoing research project into the impact of offshore windfarm electromagnetic fields on shark development reveals that the alternating electric currents produced by underwater windfarm cables seems not to disrupt the growth or survival of sharks. The research was presented
High speed video shows hippos get airborne when running
A pair of evolutionary biomechanics specialists at the University of London's, Royal Veterinary College, has found that when hippos run at full speed, all four of their feet are regularly in the air.
Not Everyone Has an Inner Voice Streaming Through Their Head
The extent to which people experience “inner speech” varies greatly, and the differences matter for performing certain cognitive tasks
From Diagnosing Brain Disorders to Cognitive Enhancement, 100 Years of EEG Have Transformed Neuroscience
The EEG has shaped researchers’ understanding of cognition for everything from perception to memory
Blue Origin logs SpaceX Starship concerns as it preps for 1st New Glenn launch
As Jeff Bezos' Blue Origin prepares for the first launch of its New Glenn rocket from Cape Canaveral this year, the company has taken time to voice concerns over future launches of competitor SpaceX's massive Starship and Super Heavy, also planning to launch from the Space Coast.
Did Hawaii just pave the way for court enforcement of California's climate promises?
Last month, 13 young Hawaiian plaintiffs were set to take the state's Department of Transportation to trial for failing to make real headway on reducing planet-warming pollution. Instead, on the eve of their court date, the youths inked a groundbreaking settlement with Hawaii's
