“The fact that an organism as old and as simple as a cyanobacterium can have photoperiodic responses suggests that this is a phenomenon that evolved much earlier than we might have imagined,” says Jabbur, who is now at the John Innes Centre in Norwich, UK.
A big part of Percy’s mission is to collect samples from interesting rocks for a future spacecraft to later bring home to Earth.
“The seeming paradox arises because of the extreme time dilation near the event horizon,” says theoretical physicist Eduardo Martín-Martínez of the University of Waterloo in Canada.
3-D printing: A means of producing physical items — including toys, foods and even body parts — using a machine that takes instructions from a computer program.
To test this idea, the team conducted experiments with quartz crystals placed in a solution containing gold and subjected to moderate pressures from an actuator.
Yet, despite their vigilance, microglia can sometimes engage in friendly fire, with a growing body of evidence suggesting they may be the engineers behind some of the brain’s most intractable conditions, such as Alzheimer’s disease and depression.
The device could be used to improve worker safety in physically demanding jobs, such as the construction industry, as well as to help sportspeople optimise their training, says John Rogers at Northwestern University in Illinois.

“The space station audio system is complex, allowing multiple spacecraft and modules to be interconnected, and it is common to experience noise and feedback.” The feedback has no technical impact on the crew or the craft’s operations, it added.
From reports of the killer whales' behavior towards sailboats, Díaz López believes the orcas are performing similar actions as they would during a hunt: repeatedly ramming the fast-moving rudder before trying to bite it.
The findings provide “a very strong indication that Alfvén waves can heat and accelerate the solar wind,” says Jean Perez, a plasma physicist at the Florida Institute of Technology in Melbourne who was not involved in the study.
