Adelaide University researchers have developed a new way to use mRNA technology to reprogram tumor-supporting immune cells and strengthen the body’s anticancer immune response.
The scientific team, spanning engineering, biomedical, oncology and immunology experts, has developed tiny, targeted particles that could help the immune system fight cancer by reprogramming immune cells within the tumor environment.
The findings have been published in Science Advances today.
The Universe still has plenty of hydrogen, but its ability to turn that fuel into new stars appears to be fading.
The Universe is producing far fewer new stars than it did billions of years ago. Over the past 4.5 billion years, the cosmic star formation rate has fallen to less than half its former level. Yet one of the most important ingredients needed to make stars has declined only modestly.
An international team led by researchers from the Chinese Academy of Sciences (CAS), working with the Dark Energy Spectroscopic Instrument (DESI) project, reached this conclusion after studying the evolution of neutral atomic hydrogen across the Universe. The researchers used China’s Five-hundred-meter Aperture Spherical radio Telescope (FAST) to make exceptionally precise measurements spanning the past 4.5 billion years.
NASA has demonstrated a new way for satellites to navigate without GPS by using the objects around them as landmarks in space.
NASA’s Starling mission has reached another milestone in spacecraft autonomy with a new system that can determine a satellite’s position by using other objects in space as reference points rather than depending on a traditional navigation network.
The FALCON (Fast Autonomous Lost-in-space Catalog-based Optical Navigation) technology demonstration represents another step toward spacecraft that can operate with greater independence. As NASA prepares for more missions beyond Earth’s orbit, systems such as FALCON could support lunar satellite swarms, distributed science missions, and future human exploration.
Neptune’s tiny moons may be ancient wreckage, preserving material exposed when a catastrophic event shattered much larger icy worlds.
In 1989, Voyager 2 discovered six previously unknown moons around Neptune. Five of them are tiny satellites that travel just beyond the planet’s main rings. Their small size and great distance from Earth have made them especially difficult to study in detail.
Now, NASA’s James Webb Space Telescope (JWST) has given scientists a much closer look. A Caltech-led team examined Neptune’s rings along with three of its moons, Larissa, Galatea, and Proteus, and found that their composition appears unlike that of other known bodies in the outer solar system.
In the mosses and lichens of the world – the in-between places, where living conditions rapidly fluctuate – lives a tiny animal with an extraordinary survival skill.
No, not tardigrades – it’s their much weirder housemate, the bdelloid rotifer.
Just like tardigrades, bdelloid rotifers can dry out almost completely and spring back to life when water returns. They can be blasted with radiation hundreds of times greater than what would kill a human, and live to tell the tale, even while their chromosomes are shattered.
We already have quantum computers, but they’re highly specialized, not particularly practical, and only cover a fraction of the performance potential that scientists think this technology could ultimately unlock.
Quantum materials can host several competing electronic states, and figuring out how those states form is a longstanding challenge – which brings us to a new study published in Nature Physics.
The study by an international team of researchers investigates how two charge density wave (CDW) phases can emerge and co-exist in the same material.
Attackers have chained two flaws in JFrog Artifactory, the repository that software build pipelines pull from, to take administrator control of self-hosted servers and plant backdoors, cloud security company Wiz said in a report.
Wiz saw the attacks between August 15 and September 8. JFrog had fixed both flaws before then, so only servers that had not been updated were open to them.
Neither flaw gives administrator control on its own.
