Biochemists create protocells to explore how lipids may have led to first cell membranes
A team of biochemists at the University of California, San Diego, working with a group of biochemical engineers from the University of California, Los Angeles, has found that the development of short lipids might have led to the development of the fi.....»»
CRISPR-based system labels extracellular vesicles with "barcodes" to better understand cell-to-cell communication
Cell-to-cell communication through nanosized particles, working as messengers and carriers, can now be analyzed in a whole new way, thanks to a new method involving CRISPR gene-editing technology......»»
Meze Audio debuts its lightest and most affordable open-back headphones
The Meze Audio 105 AER provide a much more accessible price for those who want to explore the company's open-back headphones......»»
By exerting "crowd control" over mouse cells, scientists make progress towards engineering tissues
Genes aren't the sole driver instructing cells to build multicellular structures, tissues, and organs. In a paper published in Nature Communications, USC Stem Cell scientist Leonardo Morsut and Caltech computational biologist Matt Thomson characteriz.....»»
Populations overheat as major cities fail canopy goals
A new study led by RMIT University in Australia measuring access to nature for eight major global cities found most still have inadequate canopy cover, despite access to an abundance of trees......»»
Why school police officers may not be the most effective way to prevent violence
In 1975, only 1% of public schools had their own police officers. Today, 44% do. A large reason for the increase is the Violent Crime Control and Law Enforcement Act of 1994, which led to the creation of the federal Community Oriented Policing Servic.....»»
Statistical approach improves models of atmosphere on early Earth and exoplanets
As energy from the sun reaches Earth, some solar radiation is absorbed by the atmosphere, leading to chemical reactions like the formation of ozone and the breakup of gas molecules. A new approach for modeling these reactions, developed by a team led.....»»
The new Mars landing approach: How we"ll land large payloads on the Red Planet
Back in 2007, I talked with Rob Manning, engineer extraordinaire at the Jet Propulsion Laboratory, and he told me something shocking. Even though he had successfully led the entry, descent, and landing (EDL) teams for three Mars rover missions, he sa.....»»
Redefining net zero will not stop global warming, scientists say
In a study, led by the University of Oxford's Department of Physics and published 18 November in Nature, an international group of authors who developed the science behind net zero demonstrate that relying on 'natural carbon sinks' like forests and o.....»»
New fossil reveals the evolution of flying reptiles
The pterosaurs are extinct flying reptiles that lived alongside their close relatives, the dinosaurs. The largest of these reached 10 m in wingspan, but early forms were generally limited to around 2 m. In a paper, a team led by paleontologist Dr. Da.....»»
King tides return to the San Diego coast
King tides will sweep across San Diego beaches this weekend and a few others over the next few months, sending powerful waves surging against seawalls and making for unusually low tides—prime opportunities to explore tide pools......»»
A single cell"s siesta: How non-moving single-celled organisms manage to avoid bright light
Too much of a good thing is no good at all. Living organisms enjoy sunlight—in fact, they need it to stay alive—but they tend to avoid light that is too bright. Animals go to their shelter, humans have a siesta, even plants have mechanisms to avo.....»»
Viscosity of materials key to cell differentiation: New insights could improve design of biomaterials
An IBEC-led study has revealed how mesenchymal stem cells respond to the viscosity of their environment, a key aspect in their differentiation process......»»
Long-lived Schrödinger"s-cat state achieves Heisenberg-limited sensitivity
A team led by Prof. Lu Zhengtian and Researcher Xia Tian from the University of Science and Technology of China (USTC) realized a Schrödinger-cat state with minute-scale lifetime using optically trapped cold atoms, significantly enhancing the sensit.....»»
Invisible touch: Researchers give AI the ability to feel and measure surfaces
AI-based technologies are rapidly learning to see, converse, calculate and create. One thing they still don't do well, however, is measure or "feel" surfaces—a purely mechanical function......»»
How marine worms regenerate lost body parts: Return of cells to stem cell-like state could be key
Many living organisms are able to regenerate damaged or lost tissue, but why some are particularly good at this and others are not is not fully understood. Molecular biologists Alexander Stockinger, Leonie Adelmann and Florian Raible from the Max Per.....»»
Physicists predict exotic form of matter with potential for quantum computing
MIT physicists have shown that it should be possible to create an exotic form of matter that could be manipulated to form the qubit (quantum bit) building blocks of future quantum computers that are even more powerful than the quantum computers in de.....»»
Gemini gets image creation trick in Docs and Calendar access in Gmail
Gmail users will now be able to directly access Calendar information and take relevant actions. In Docs, users can now create images using the Imagen 3 model......»»
Selenoproteins open new strategies for treating certain cancers in children
Selenoproteins are crucial for several biological functions, including the breakdown of harmful substances, immune system support, and regulating metabolic processes. However, in specific contexts, these proteins can be misused and shield cancer cell.....»»
Methylmercury: How microbes create the most toxic form of mercury
Mercury is extraordinarily toxic, but it becomes especially dangerous when transformed into methylmercury—a form so harmful that just a few billionths of a gram can cause severe and lasting neurological damage to a developing fetus. Unfortunately,.....»»
Ancient climate study links past ocean acidification to current trends
A research team led by Prof. Li Mingsong at Peking University has provided new insights into the Paleocene-Eocene Thermal Maximum (PETM) and its effects on ocean chemistry......»»
