At the Max Rady College of Medicine, University of Manitoba, in Canada, researchers have developed a stem-cell-based therapy that is regenerating spinal cords in laboratory animals and may become available for human clinical trials.
Blocking inhibitory molecules that cause neuronal cells to degenerate, and inhibit stem cell transplants may prove a breakthrough therapy.
Glowing spider fossils prompt breakthrough study of how they were preserved at Aix-en-Provence.
A geologic formation near Aix-en-Provence, France, is renowned as one of the world’s most important treasure troves of Cenozoic Era fossil species. Scientists have been uncovering exceptionally well-preserved fossilized plants and animals there since the late 1700s.

High-amplitude ultrasound pulses have been used to partially destroy liver tumors in rats, triggering the rodents’ immune systems to clear the remaining cancerous cells and prevent the disease from spreading or returning. Presenting their findings in the journal Cancers, the researchers behind this breakthrough say their technique could lead to effective, non-invasive treatments for some of the most intractable cancers in human patients.
Liver cancer certainly falls into that category, and is associated with a five-year survival rate of just 18 percent in the US. Though many treatment options are available, liver tumors have a tendency to metastasize or recur after these interventions.
In their study, the authors explain that conventional cancer treatments like chemotherapy, radiotherapy, and thermal ablation are effective at destroying tumors, yet also trigger a somewhat unpredictable immune reaction which can be anti-tumor or pro-tumor. Furthermore, they note that the size, location, and stage of a tumor can sometimes make it impossible to target the entire tissue mass with existing treatments.

To understand the nature of our galaxy, astronomers had to look to distant island universes.
Turn your eyes toward the night sky and you will see a bright, hazy band of light cutting across the sky.
For millennia, observers speculated about the Milky Way’s true nature. The Greeks said the streak of haze in the sky was milk spurting from the breast of the goddess, Hera, Egyptians thought it was cows’ milk, and some Aboriginal Australians thought it was a river flowing through the sky.
Today, we know that we are looking along the plane of our spiral galaxy, consisting of at least 100 billion stars. But understanding the shape of the Milky Way proved elusive up until the 20th century. The problem is we can’t get a bird’s eye view of our galaxy because our solar system is buried within the galaxy. But with the invention of the telescope, photography, spectroscopy, and radio astronomy, we have uncovered the shape and size of our home galaxy — and our place among the billions of stars that make up our island universe.
CUORE Team Places New Limits on the Bizarre Behavior of Neutrinos Physicists are closing in on the true nature of the neutrino — and might be closer to answering a fundamental question about our own existence. In a Laboratory under a mountain, physicists are using crystals far colder than frozen air to study ghostly particles, hoping to learn secrets from the beginning of the universe. Researchers at the Cryogenic Underground Observatory for Rare Events (CUORE) announced this week that they had placed some of the most stringent limits yet on the strange possibility that the neutrino is its own antiparticle. Neutrinos are deeply unusual particles, so ethereal and so ubiquitous that they regularly pass through our bodies without us noticing. CUORE has spent the last three years patiently waiting to see evidence of a distinctive nuclear decay process, only possible if neutrinos and antineutrinos are the same particle. CUORE’s new data shows that this decay doesn’t happen for trillions of trillions of years, if it happens at all. CUORE’s limits on the behavior of these tiny phantoms are a crucial part of the search for the next breakthrough in particle and nuclear physics – and the search for our own origins.
From self-replicating molecules in Archean seas, to eyeless fish in the Cambrian deep, to mammals scurrying from dinosaurs in the dark, and then, finally, improbably, ourselves – evolution shaped us.
Organisms reproduced imperfectly. Mistakes made when copying genes sometimes made them better fit to their environments, so those genes tended to get passed on. More reproduction followed, and more mistakes, the process repeating over billions of generations. Finally, Homo sapiens appeared. But we aren’t the end of that story. Evolution won’t stop with us, and we might even be evolving faster than ever.
It’s hard to predict the future. The world will probably change in ways we can’t imagine. But we can make educated guesses. Paradoxically, the best way to predict the future is probably looking back at the past, and assuming past trends will continue going forward. This suggests some surprising things about our future.
The future of solar has just got brighter with this ‘ultra-thin’ device for converting stored energy into electricity.
WASHINGTON – The U.S. Space Force in 2025 plans to launch to geostationary orbit three small satellites that will attempt to dock with a propellant tanker so they can be refueled in space.
The idea is to “test out pieces of the refueling infrastructure,” Col. Joseph Roth, director of innovation and prototyping at U.S. Space Systems Command, told SpaceNews last week at the Space Symposium in Colorado Springs.
The $50 million experiment, called Tetra-5, is run by the Space Force’s Space Enterprise Consortium. Bids for the project closed earlier this month.
Airbus has completed wind-tunnel testing of its eXtra Performance Wing demonstrator in its quest to quickly test and accelerate advanced innovative technologies that will decarbonize the aviation industry. The demonstrator model was tested in the Filton wind tunnel near Bristol, England.
Launched last September, the eXtra Performance Wing project takes inspiration from nature to improve wing aerodynamics and performance. It is intended to be compatible with any future aircraft configuration and propulsion system to reduce CO2 emissions.
To make a more efficient aircraft with lower carbon footprints, Airbus is testing wing technologies that are based on the behavior of bird flight with wings. Initially, the technology was introduced at a smaller scale through another Airbus project, AlbatrossONE, which tested semi-aeroelastic hinged wings that – like the seabird – unlocked during the flight when experiencing wind gusts or turbulence. Now, the eXtra Performance Wing will also examine new technologies, including gust sensors, pop-up spoilers, and multifunctional trailing edges to enable active control of the wing.
MIT has launched a new academia and industry partnership called the AI Hardware Program that aims to boost research and development.
“A sharp focus on AI hardware manufacturing, research, and design is critical to meet the demands of the world’s evolving devices, architectures, and systems,” says Anantha Chandrakasan, dean of the MIT School of Engineering, and Vannevar Bush Professor of Electrical Engineering and Computer Science.
