Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein amyloid-β (Aβ) between brain cells, ultimately resulting in the formation of so-called amyloid plaques. https://phys.org/news/2026-08-gold-nanoclusters-alzheimer-amyloid-plaques.html Bio & Medicine Mon, 17 Aug 2026 10:00:01 EDT news706177996 New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device.

In nature, this can occur through passive transport, known as diffusion. "Biological systems often use mechanical motion to accomplish tasks that cannot be achieved by diffusion alone," says Professor Laura Na Liu, director of the 2nd Physics Institute at the University of Stuttgart. For example, certain bacteria use extracellular contractile injection systems. These molecular nanomachines puncture target cells and deliver molecular cargo. https://phys.org/news/2026-08-dna-origami-nanosyringe-molecules-synthetic.html Bio & Medicine Tue, 11 Aug 2026 14:00:01 EDT news705666602 A joint research team—led by professor Young Seok Cho from the School of Medicine, alongside professor James J.

Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon chains, which makes it hydrophobic and insoluble in water. Mixtures of the two are called emulsions, and emulsifiers exist that can stabilize them into a thicker temporary or permanent mixture. Cooks use such a technique to make vinaigrette, a salad dressing consisting primarily of oil and vinegar with emulsifiers such as mustard, honey or mayonnaise. https://phys.org/news/2026-06-nanoscale-droplets-dont-coalesce-microscale.html Bio & Medicine Mon, 29 Jun 2026 09:00:04 EDT news701942376 Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies on ultrathin engineered materials.
