Phys.org / Comb jelly embryos reveal embryonic signaling center shared across early animal evolution
In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, left and right, and ...
Medical Xpress / An intranasal flu vaccine approved two decades ago may have underappreciated immune benefits
For decades, influenza vaccines have been judged largely by the antibodies they generate in the bloodstream, a measure that has remained the gold standard since the first flu immunizations were administered in the 1940s.
Phys.org / Drug-free nanoparticles stop tumor growth by transmitting biological messages to immune cells
A research team from the Technion's Wolfson Faculty of Chemical Engineering has developed an original technology for treating cancer using nanoparticles that carry no drugs at all and has demonstrated its effectiveness against ...
Medical Xpress / First-of-its-kind exoskeleton therapy could redefine how stroke survivors relearn to walk
Each year, nearly 800,000 Americans survive a stroke. For many, the journey to recovery includes relearning one of life's most fundamental activities: walking. Weakness, impaired coordination and reduced control of the legs ...
Medical Xpress / Gazing longer at something contributes to memory encoding, study finds
While humans are observing their surroundings, their eyes tend to rapidly shift between different objects, people and details that catch their attention, pausing briefly on each one. In psychology, prolonged pauses on specific ...
Phys.org / Dozens of active dust devils caught swirling across Mars canyon system
The European Space Agency's Mars Express has captured part of Mars's Mamers Valles, a fascinating valley system speckled with brief, tornado-like whirlwinds known as dust devils.
Science X / One-of-a-kind Iron Age mother-of-pearl seal unearthed at Tel Hadid, Israel
A tiny, iridescent shell seal found in an ancient garbage pit in Israel is the first of its kind ever found in the region and may have belonged to a community deported and relocated by one of the ancient world's mightiest ...
Medical Xpress / Kidney healing improves after protein blockade, with less scarring and faster recovery
A drug previously developed at UCLA to help heart tissue repair itself after a heart attack might also help kidney tissue repair and regenerate, researchers have found.
Medical Xpress / Colorectal tumors use mitochondrial complex II to stockpile iron, but eliminating it causes cell death
Scientists know that colorectal cancer cells require large amounts of iron and that as cancer becomes more aggressive, the cells have even higher amounts of iron. Normal cells with high levels of iron would undergo a type ...
Phys.org / When glaciers vanish, so does the hidden life they support
We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international ...
Medical Xpress / Pakistani genomes reveal 34,000 knockouts that could explain why mouse-based drugs fail in humans
A comprehensive analysis of 173,303 genomes from Pakistan, published today in Nature, is upending how scientists understand human genetics and drug development. By identifying 34,000 people who are "human knockouts," with ...
Tech Xplore / Electric 'nose' can smell when your food's gone bad
Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. ...
