Unraveling the mechanisms that create the individualized metabolism in leukemia
Lysine-specific demethylase 1 (LSD1), an enzyme involved in gene expression, produces individualized metabolism depending on the type of acute myeloid leukemia cells. Cancer cells have a unique ability to metabolize substances differently from normal.....»»
Citizen scientists create buzz with new insect discovery
More than 60% of Australia's known insects are unnamed and a mystery to science. Of an estimated 500,000 Australian species, roughly half are insects, but many aren't categorized......»»
Unraveling the mystery of dormancy in food pathogens for more effective elimination
Listeria monocytogenes, a bacterium that causes listeriosis, a serious disease, can go into dormancy when confronted with environmental stress, for example in the presence of detergents or in water devoid of nutrients. It then becomes undetectable by.....»»
Researchers create orientation-independent magnetic field-sensing nanotube spin qubits
Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes (BNNTs) containing spin qubits, or spin defects. The BNNTs are more sensitive in detecting off-axis magnetic fields at high resolution than traditiona.....»»
Influence of a black hole"s spin: First evidence of precession in ultraluminous accretion disks
Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe, emit light and plasma jets. When a black hole spins on its axis,.....»»
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.....»»
Nanopillars create tiny openings in the nucleus without damaging cells
Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells.....»»
Breeder who tried to create enormous trophy sheep jailed in US
A man who tried to breed enormous hybrid sheep using genetic material from endangered animals so he could sell them to trophy hunting ranches has been sentenced to six months in prison, the US Department of Justice said Monday......»»
New mission to create total solar eclipses in space
A UK team of researchers including UCL's Professor Lucie Green are working on the launch of a spacecraft mission that will allow us to view the sun's atmosphere in more detail than ever before......»»
Google gives Gemini a boost in Sheets and a cool trick in NotebookLM
Using text prompts, Google Sheets can now create structured tables instead of plain text layouts, while NotebookLM will break down YouTube videos......»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
The biological marvels of the seabed are being mined to create commercial products—here are the risks
Thousands of genes from deep-sea marine life are being used to create new commercial products ranging from pharmaceuticals to cosmetics. Genes are segments of DNA that provide instructions for making other molecules that are essential for the structu.....»»
Future climate change predicted to shift flood-generating mechanisms and intensify extreme flooding events
The Delaware River Basin, a coastal watershed in the Mid-Atlantic region, has a long history of severe flooding with significant socioeconomic impacts. Recent research uses a process-based modeling approach to analyze hydrometeorological (like rainfa.....»»
Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time but is impossible to.....»»
Cryo-ET study provides viral close-up of HTLV-1, the "overlooked cousin of HIV"
In collaboration with the University of Minnesota and Cornell University, Martin Obr and Florian Schur from the Institute of Science and Technology Austria (ISTA) provide new details into the architecture of HTLV-1 (Human T-cell Leukemia Virus Type 1.....»»
UN chief says sea level rise threatens "rising tide of misery"
United Nations Secretary-General Antonio Guterres warned on Wednesday that rising sea levels threaten to create "a rising tide of misery" for millions, with intense storm surges, coastal erosion and coastal flooding increasingly likely......»»
Studying fossil extraction on Native lands and exploring the depths of untold histories
In 2019, historian Lukas Rieppel published a book about the history of dinosaur fossils and their excavation in the late 1800s to create museum displays......»»
Quantum sensing approach captures nanoscale electrochemical evolution in battery
Battery performance is heavily influenced by the non-uniformity and failure of individual electrode particles. Understanding the reaction mechanisms and failure modes at nanoscale level is key to advancing battery technologies and extending their lif.....»»
