Doctors and scientists have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.
If you're a night owl looking to invest in the next big startup, making that decision first thing in the morning might not be the best idea, according to a new study.
Efforts to protect threatened and endangered species in central Africa might be more successful if they focused on a smaller geographic area, new research suggests.
Archaeologists have discovered remains of a Roman arched aqueduct during excavation work on the Hellenistic royal city of Artashat-Artaxata in ancient Armenia. It is the easternmost arched aqueduct in the Roman Empire.
New supercomputer simulations show that after creating a ring, a planet can move away and leave the ring behind. Not only does this bolster the planet theory for ring formation, the simulations show that a migrating planet can produce a variety of patterns matching those actually observed in disks.
A new study measured respiratory particles produced from people singing or playing instruments. Is singing worse than talking when it comes to how many particles are being emitted? Yes, according to the study. And the louder one talks or sings, the worse the emissions. A person's age and whether they are male or female also affects their respiratory emissions, with males and adults emitting more airborne particles, on average, than females and minors.
The NASA/ESA Hubble Space Telescope has captured a striking new photo of the edge-on spiral galaxy UGC 11537. UGC 11537 is located approximately 217.5 million light-years away in the constellation of Aquila. Also known as IRAS 20160-0018 or LEDA 64458, the galaxy lies close to the plane of the Milky Way. “Being so close to [...]
The structural characteristics of biological specimens, such as wet proteins and living cells, can be conveniently probed in their host aqueous media using soft X-rays. Conventional X-ray detectors in this area have low spatial resolution, limited sensitivity, and require complex fabrication procedures. Many of these limitations are overcome by introducing a direct soft X-ray detector [...]
ESO’s VLT Survey Telescope (VST) has produced a spectacular image of NGC 3314, a pair of spiral galaxies located in the direction of the Hydra I cluster. NGC 3314 consists of the spiral galaxy NGC 3314A in front of the spiral galaxy NGC 3314B. “Don’t let the perspective fool you! They are, in fact, not [...]
Patients with mitral and tricuspid valve regurgitation, a condition sometimes called 'leaky heart valves,' appeared to do better after two years if they had a tricuspid valve repair at the time of mitral valve surgery, according to a new study.
In a new study designed to better understand and combat these structures, scientists identified some of the key proteins in biofilms of the fungus Candida albicans that control both how they resist antifungal drugs and how they become dispersed throughout the body.
Clotting problems and resulting complications are common in COVID-19 patients. Researchers have now shown that a member of the anticoagulant group of drugs not only has a beneficial effect on survival of COVID-19 patients, but also influences the duration of active infection with the SARS-CoV-2 coronavirus.
Even though most COVID-19 cases come from exposure to airborne coronavirus, a new study points to the importance of surfaces as a reservoir of risk in nursing homes -- especially certain objects close to the beds of patients who have COVID-19.
Green hydrogen production from solar water splitting has attracted a great deal of interest in recent years because hydrogen is a fuel of high energy density. A research team discovered the quantum confinement effect in a photocatalyst of a 3D-ordered macroporous structure. The quantum confinement effect was found to enable hydrogen production under visible light. The findings offer an option for addressing energy and environmental challenges.
Researchers probing the gut -- 'the inner tube of life' -- have for the first time discovered specific factors in its workings that in the future may help improve treatment for patients facing gut damage or gastrointestinal disease.
A team of researchers has developed a new technique to open the blood-brain barrier temporarily to deliver medication to the brain. Getting medication past the brain's unique and protective blood vessels, known as the blood-brain barrier, is one of the biggest challenges in treating brain and central nervous system diseases, according to researchers. The technique uses light and nanoparticles to pry open temporarily these barriers -- called tight junctions -- to allow medication to reach its target.
A team has developed a digital tool to better monitor a condition known as Barrett's esophagus, which affects more than 3 million people in the United States. Barrett's occurs when the mucosal lining of the lower esophagus deteriorates, altering its cellular structure, and is most common in those with chronic acid reflux.
Imagine a world in which smart packaging for supermarket ready meals updates you in real-time to tell you about carbon footprints, gives live warnings on product recalls, and instant safety alerts because allergens were detected unexpectedly in the factory. But how much extra energy would be used powering such a system? And what if an accidental alert meant you were told to throw away your food for no reason?
