Predictors for radiotherapy success may help some rectal cancer patients avoid surgery

Posted by in category: biotech/medical

Recent research from the S: CORT team has identified key biomarkers and treatment strategies that predict and enhance effectiveness of radiotherapy in rectal cancer treatment.

Patients with advanced rectal cancer often receive radiotherapy before surgery. However, despite this being standard practice, this treatment only results in complete disappearance (complete response) prior to surgery in 15% of patients.

Currently, there are no reliable biomarkers (a biological molecule found in blood, other , or tissues that is a sign of a normal or abnormal process, or of a condition or disease) to predict which colorectal patients will benefit from radiotherapy, meaning that many patients are unnecessarily exposed to significant side effects.

Scientists find promising new target for antidepressants—in the gut

Posted by in categories: biotech/medical, neuroscience

Researchers have discovered new connections between the gut and brain that hold promise for more targeted treatments for depression and anxiety, and could help prevent digestive issues in children by limiting the transmission of antidepressants during pregnancy.

The study, published in the journal Gastroenterology, shows that increasing serotonin in the gut epithelium—the thin layer of cells lining the small and large intestines—improves symptoms of anxiety and depression in animal studies. The researchers also found that, in humans, antidepressant use during increases the risk of babies developing constipation in the first year of life.

“Our findings suggest that there may be an advantage to targeting antidepressants selectively to the gut epithelium, as systemic treatment may not be necessary for eliciting the drugs’ benefits but may be contributing to digestive issues in children exposed during pregnancy,” said Kara Margolis, director of the NYU Pain Research Center and associate professor of molecular pathobiology at NYU College of Dentistry, who co-led the study with Mark Ansorge, associate professor of clinical neurobiology at Columbia University.

Firefly Sparkle: ‘Christmas’ galaxy reveals how Universe formed

Posted by in category: space

NASA’s James Webb Space Telescope (JWST) has for the first time captured an image of what our galaxy likely looked like just as it was forming — and it’s got space scientists feeling very Christmassy.

“I just love the sparkle galaxy with its Christmas lights shining as it was when the Universe was just 600 million years old,” Prof Catherine Heymans, Scotland’s Astronomer Royal, told BBC News.

The image shows ten balls of stars of different colours, appearing like Christmas tree baubles hanging in the cosmos.

Another record has been set for the most entangled logical qubits

Posted by in categories: computing, quantum physics

Just a few months after the previous record was set, a start-up called Quantinuum has announced that it has entangled the largest number of logical qubits – this will be key to quantum computers that can correct their own errors.

New technique for spotting Dyson rings unveiled

Posted by in categories: energy, satellites

Dyson spheres and rings have always held a special fascination for me. The concept is simple: build a great big structure either as a sphere or ring to harness the energy from a star. Dyson rings are far more simple and feasible to construct and in a recent paper a team of scientists explore how we might detect them by analyzing the light from distant stars. The team suggests they might be able to detect Dyson rings around pulsars using their new technique.

Like their spherical cousins, Dyson rings remain for now, a popular idea in yet they are starting to appear more and more in scientific debates. The concept of the ring is similar to the sphere, a megastructure designed to encircle a star, harnessing its energy on a gargantuan scale.

It might consist of a series of satellites or even habitats in a with solar collectors and unlike the spheres, require far less resources to build. The concept of the sphere was first proposed by physicist and mathematician Freeman Dyson in 1960. Such structures might be detectable and reveal the existence of intelligent civilizations.
