Could we harness energy from black holes? A new study indicates energy can be extracted from black holes through reconnection of magnetic field lines — ScienceDaily

A remarkable prediction of Einstein’s theory of general relativity — the theory that connects space, time, and gravity — is that rotating black holes have enormous amounts of energy available to be tapped. For the last 50 years, scientists have tried to come up with methods to unleash this power. Nobel physicist Roger Penrose theorized […]

Striving for a better understanding of pest resistance in experimental lines

Credit: Gurjit Singh Tifton, Georgia: A study out of the University of Georgia sought to determine the level of host plant resistance that can be assured by several promising experimental bermudagrass genotypes against potential damages committed by the fall armyworm. Researchers Gurjit Singh, Shimat Joseph, and Brian Schwartz evaluated […]

Researchers find that timing of mass extinctions lines up with asteroid impacts and massive volcanic eruptions — ScienceDaily

Mass extinctions of land-dwelling animals — including amphibians, reptiles, mammals, and birds — follow a cycle of about 27 million years, coinciding with previously reported mass extinctions of ocean life, according to a new analysis published in the journal Historical Biology. The study also finds that these mass extinctions align with major asteroid impacts and […]
