Researchers discovered that the practice of subsurface fluid injection often used in oil and gas exploration could cause significant, rapidly spreading earthquake activity beyond the fluid diffusion zone. The results account for the observation that human-induced earthquake activity often surpasses natural earthquake hotspots.

Las células cancerosas esconden dentro de sus mangas metafóricas varios trucos para sobrevivir la quimioterapia, la radioterapia y otros tratamientos contra el cáncer. Pero ahora, mediante líneas celulares y células derivadas del cáncer de algunos pacientes, los investigadores de Mayo Clinic descodificaron uno de esos trucos y propusieron una manera de volver a sensibilizar a las células del cáncer de mama al tratamiento.

New computer program uses artificial intelligence to determine what visual neurons like to see. Algorithm generates synthetic images that morph into “super stimulus” for neurons, removing inherent bias of using natural images to gauge preferences. The approach could shed light on learning disabilities, autism spectrum disorders and other neurologic conditions.

Even if concrete is not flammable, it can be hazardous in tunnel fires: high-performance concrete can explode at high temperatures. Although the phenomenon is well known, the physics behind it have not yet been fully understood. Empa researchers have now made the processes inside concrete visible for the first time using real-time-neutron radiography and tomography.

ALBUQUERQUE, N.M. — When traveling at five times the speed of sound or faster, the tiniest bit of turbulence is more than a bump in the road, said the Sandia National Laboratories aerospace engineer who for the first time characterized the vibrational effect of the pressure field beneath one of these tiny hypersonic turbulent spots.

A team of plastic surgeons and material scientists has made an important advance in treating the common clinical problem of soft tissue loss. They have invented a synthetic soft tissue substitute that is well tolerated and encourages the growth of soft tissue and blood vessels. This new material retains its shape without being too dense, overcoming challenges with current tissue fillers that tend to be either too soft or not porous enough to let cells move in and start regrowing tissue. A report on this work appears today in Science Translational Medicine.

Shock wave studies allow researchers to achieve the warm dense matter that’s found only in the extreme conditions around stars and created in the laboratory for inertial confinement fusion research, and researchers in Israel recently set out to understand the relation, if any, between the evolution of a shock wave and the expansion of the exploding wire. They describe their work in the Physics of Plasmas.

Acorn Woodpeckers live in close-knit family groups and have one of the most complex breeding systems of any bird in the world. In about 20 percent of family groups, up to 3 related females may lay eggs in the same nest. They raise the chicks cooperatively with one or more related males. This behavior is known as joint nesting or “cooperative polyandry.” Only five other species of birds worldwide are known to do this. The reasons that may be driving the behavior are outlined in a study recently published in The American Naturalist.
