Non-invasive blood test shows 83% sensitivity in detecting colorectal cancer, offering hope for early diagnosis

Posted by in category: biotech/medical

In a recent study published in The New England Journal of Medicine, a team of scientists from the United States (U.S.) and Canada evaluated the performance of a blood-based testing method that uses cell-free deoxyribonucleic acid (DNA) to screen for colorectal cancer.

Scientists proved the fundamental limits of electromagnetic energy absorption

Posted by in categories: energy, mathematics

Until recently, researchers were unsure of the minimum thickness of a transparent substance required to take in a given quantity of light.

Konstantin N. Rozanov of the Institute for Theoretical and Applied Electrodynamics in Russia discovered more than two decades ago the amount of light that a gadget might absorb at various wavelengths if one side of it was coated in metal. This metal establishes a barrier where light is absorbed or bounced back, simplifying the mathematical solution.

Ultraviolet Radiation from Massive Stars Shapes Planetary Systems

Posted by in categories: materials, space

Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.

Can gut bacteria help shape newborn’s immune system? Study sheds light

Posted by in categories: biotech/medical, food, health, neuroscience

Researchers from Weill Cornell Medicine have discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells that help in preventing allergic reactions to food and the bacteria themselves during early development.

The study published in the journal Science Immunology on March 15, 2024, revealed that bacteria abundant in the guts of newborns produce serotonin, which promotes the development of immune cells called T-regulatory cells or Tregs. These cells suppress inappropriate immune responses to help prevent autoimmune diseases and dangerous allergic reactions to harmless food items or beneficial gut microbes.

Scientists harness food by-products to fight antimicrobial resistance

Posted by in categories: biotech/medical, food

Scientists are embarking on a £1.1 million project aimed at revolutionising drug production by using food by-products to develop new antimicrobial drugs.

Led by the University of Strathclyde in collaboration with the University of Surrey and GSK, the research endeavours to make antimicrobial production more cost-effective and sustainable, thereby addressing the pressing global challenge of antimicrobial resistance.

The project seeks to leverage bacteria, particularly Streptomyces, known for their potential to produce various drugs including antimicrobials. By harnessing food by-products, the team is aiming to device a less carbon-intensive process for biomanufacturing, which could pave the way for a range of medications including anti-parasitic, anti-cancer, anti-fungal, and immunosuppressant drugs.

New cardiovascular imaging approach provides a better view of dangerous plaques

Posted by in categories: biotech/medical, engineering, health

Researchers in the UC Davis Department of Biomedical Engineering are introducing a groundbreaking catheter-based device that could revolutionize heart attack and stroke prevention by enhancing intravascular imaging of dangerous plaques.


Researchers in the Department of Biomedical Engineering at the University of California, Davis, have developed a new catheter-based device that combines two powerful optical techniques to image the dangerous plaques that can build up inside the arteries that supply blood to the heart. By providing new details about plaque, the device could help clinicians and researchers improve treatments for preventing heart attacks and strokes.

Atherosclerosis occurs when fats, cholesterol and other substances accumulate on the artery walls, which can cause these vessels to become thick and stiff. A heart attack or stroke may occur if an atherosclerotic plaque inside the blood vessels ruptures or parts of it break off.

MIT Unveils the Dance of Protons: Pioneering Energy’s New Era

Posted by in categories: chemistry, energy

New insights into how proton-coupled electron transfers occur at an electrode could help researchers design more efficient fuel cells and electrolyzers.

A key chemical reaction — in which the movement of protons between the surface of an electrode and an electrolyte drives an electric current — is a critical step in many energy technologies, including fuel cells and the electrolyzers used to produce hydrogen gas.

For the first time, MIT chemists have mapped out in detail how these proton-coupled electron transfers happen at an electrode surface. Their results could help researchers design more efficient fuel cells, batteries, or other energy technologies.

Unlocking Quantum Secrets: The Revolutionary Dance of Nanoparticles

Posted by in categories: nanotechnology, particle physics, quantum physics

Innovative research leverages levitated optomechanics to observe quantum phenomena in larger objects, offering potential applications in quantum sensing and bridging the gap between quantum and classical mechanics.

The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research published today, scientists demonstrate a novel platform that could help us find an answer.

The laws of quantum physics govern the behavior of particles at minuscule scales, leading to phenomena such as quantum entanglement, where the properties of entangled particles become inextricably linked in ways that cannot be explained by classical physics.
