Possible outpatient relief for millions of older men: MD researcher develops improved technology to shrink enlarged prostate glands without surgery

A new technology developed by Dr. Lawrence Larsen at Sandia National Laboratories can treat benign prostatic hyperplasia (BPH) without surgery, reducing side effects and costs. The non-invasive procedure uses radio frequency energy to kill excess cells, shrinking the prostate gland and alleviating urinary obstruction and pain.

Why, in Superbowl of statistical mechanics, famous players could never cross goal line: 3-D proof for Ising model impossible, researcher proves

Computational biologist Sorin Istrail shows that the solution of Ising's model cannot be extended into three dimensions for any lattice, making exact solutions unattainable. The model, developed by Ernst Ising in 1926, has been extensively studied in one and two dimensions but remains unsolvable in three dimensions.

Keeping one’s distance not always a bad thing: repulsion between quantum dots helps determine lasing characteristics, researchers find

Researchers have discovered that quantum dots repel each other, which may govern their self-organization and be crucial for controlling dot characteristics. This effect can help form more uniform and orderly arrays of dots, leading to improved lasing frequency and intensity.

Some, Like Russian Dolls, Fit Inside Each Other: Self-Assembled Nanospheres May Be Helpful Against Disease Or Terrorism, Or As Fillers And Coatings

Researchers have created self-assembling nanospheres that can control the release of drugs and have superior characteristics to traditional fillers. These durable silica spheres range in size from 2-50 nanometers and can absorb organic and inorganic substances, making them useful for various applications.

Sandia Photonic Crystal Confines Optical Light: 'Very Important Work,' Says Physics Nobel Iaureate

Researchers at Sandia National Laboratories have created a microscopic three-dimensional lattice that confines light at optical wavelengths, potentially revolutionizing the fiber-optics communications industry. The technique appears to be the cheapest and most efficient way to bend light entering or emerging from optical cables.

Microscopic Machines May Replace Quartz Crystals: Pollen-Grain-Sized Parts May Appear In Watches, TVs, Computers

Researchers at Sandia National Laboratories have developed a microelectromechanical system (MEMS) prototype that functions as a clock source, replacing traditional quartz crystals. The MEMS devices are made from polysilicon and can be built on one chip with integrated circuits, reducing manufacturing costs and increasing reliability.
