Cancer-promoting Ras protein exists in a pair within cells
Researchers from Bochum and Osnabrück have gained new insights into the structure of the Ras protein, which acts as a molecular switch for cell growth and is involved in the development of cancer. With the help of fluorescence markings, they have de.....»»
Natural compound found in flowers blocks activity of an enzyme involved in multiple sclerosis and cancer
Scientists have identified a natural compound that halts the process involved in the progression of certain forms of cancer and demyelinating conditions—those that damage the sheath, known as myelin, that surrounds neurons—such as multiple sclero.....»»
When ribosomes go rogue
Unusual variations in the cellular protein factory can skew development, help cancer spread, and more. But ribosome variety may also play biological roles, scientists say. In the.....»»
Live-cell imaging under centrifugation: New method measures the forces that keep the nuclei of living cells centered
Using two specialized microscopes invented at the Marine Biological Laboratory (MBL), a team of researchers from Japan and the MBL have developed a new method to measure the forces that keep the nucleus centered within a living cell. The experiments.....»»
River flow responses to heat waves may change more rapidly under climate change, research finds
A pair of studies by researchers in Simon Fraser University's School of Environmental Science examine how climate change could alter the way Canadian rivers respond to extreme heat events......»»

New technology illustrates bacterial "hibernation states"
Like hibernating bears, certain bacterial cells have the ability to shift into a "low-power" metabolic state in which they can stably survive without growing. This state is often seen in the context of antibiotic-resistant infections as bacteria form.....»»
An elegant switch regulates production of protein variants during cell division
Our cells contain thousands of proteins that have gone largely undetected and unstudied until recent years: these are variants of known proteins, which cells can make when their protein-building machinery interacts differently with the same stretch o.....»»

Meet the winners of Nikon’s 2024 photomicrography contest
Nikon Small World photomicrography contest is an annual reminder that science can be beautiful as well as informative. A stunning image of differentiated mouse brain tumor cells h.....»»
Enhancing recombinant protein expression in lettuce
Recombinant proteins are crucial in pharmaceutical and other industries. A production method uses plants as hosts in transient protein expression systems. Researchers at the University of Tsukuba developed a technique to increase recombinant protein.....»»
On Lake Erie, getting rid of problem algae starts with giving it less food
On a warm late-summer evening, a small speedboat motored across a pea-green stretch of Lake Erie past a beach where a child sat splashing and a pair of newlyweds waded for a portrait photographer. On the sand, unseen or ignored, bright red signs warn.....»»
Exploring the authenticity of a pair of storied gloves rumored to belong to Shakespeare
The leather gloves, embroidered at the wrists, rest on a tufted pillow of red satin in a glassed wooden box, a fitting place for artifacts that have a history tied to the English-speaking world's most-famous playwright......»»
Nanoparticle technology demonstrates selective destruction of leukemia cancer cells
A research team, affiliated with UNIST has developed nanoparticles that effectively treat acute myeloid leukemia (AML), offering the potential to reduce side effects while enhancing therapeutic efficacy by selectively targeting and eliminating leukem.....»»
Discovery of new bacterial toxins could be key to fighting infections
Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments for infections. These toxins, found in over 100,000 microbial genomes, can destroy the cells of bacteri.....»»
Education and gender equality: Focus on girls isn"t fair and isn"t enough, say researchers
For the past two decades, investing in girls' schooling has been hailed as a cornerstone of promoting gender equality in sub-Saharan Africa. Between 2016 and 2018, the World Bank Group invested US$3.2 billion in education projects benefiting adolesce.....»»
How Cells Resist the Pressure of the Deep Sea
Cell membranes from comb jellies reveal a new kind of adaptation to the deep sea: curvy lipids that conform to an ideal shape under pressure......»»
Deciphering the language of cells: How they sense and respond to mechanical forces
Cells, the fundamental building blocks of life, are constantly subjected to a variety of mechanical forces within our bodies. These forces, which can arise from both internal and external sources, play crucial roles in regulating cellular processes s.....»»
Scientists find southern killer whales of the Pacific have access to enough food, deepening mystery of their struggles
A pair of marine mammal scientists at The University of British Columbia, has found that claims that a lack of access to salmon is what is driving the crash in population numbers for southern resident killer whales of the Pacific are wrong......»»
Team achieves successful reproduction of hematopoietic stem cell developmental process in an in vitro culture system
Researchers at Kumamoto University have achieved a notable advancement in stem cell biology by reproducing the developmental process of hematopoietic stem cells (HSCs) in vitro. This culture system not only enhances our understanding of how HSCs deve.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
