Urine samples collected from wild chimpanzees in Uganda over decades have revealed older female chimps undergo hormonal changes much like those in menopausal humans.
Researchers have developed a new mechanism to make water droplets slip off surfaces, described in a paper published in Nature Chemistry. The discovery challenges existing ideas about friction between solid surfaces and water and opens up a new avenue for studying droplet slipperiness at the molecular level. The new technique has...
The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing our reality are simply algorithms. The experiences we have are generated by the computational processes of an immensely advanced...
Technique developed at the University of Michigan-histotripsy- provides a noninvasive alternative to surgery, chemotherapy and radiation treatments for cancer. Histotripsy works by using targeted ultrasound waves for killing tumor cells. Beyond tumor destruction, the technique may also activate the immune system against cancer...
The main diagnostic test for obesity — the body mass index — accounts for only height and weight, leaving out a slew of factors that influence body fat and health.
An experiment found that the brain uses one set of neural circuits to identify the numbers 1–4; these circuits are very specific to their own numbers. A separate set of circuits respond to the numbers 5–9; these are less precise, and are activated by adjacent numbers....
Researchers have demonstrated a general strategy to achieve the long-term stability of plastrons (known to be unstable underwater) on aerophilic surfaces for previously unattainable underwater applications by taking inspiration from diving bell spider, Argyroneta Aquatica, which spends most of its life underwater. This can open...
