Early May is a good time to watch for a powerful yet often elusive meteor shower, the annual Eta Aquariids. They’re a prolific, yet often elusive for northern hemisphere observers. If skies are clear, watch for a strong annual meteor shower that’s attained an almost mythical status: the May Eta Aquariids. Go to Source […] Expose an animal to extreme physical stress, and the expectation is simple: It will break down. But when UC Riverside scientists subjected fruit flies to forces many times stronger than Earth’s gravity—a condition called hypergravity—the insects did something unexpected. They survived. They even mated and reproduced. Their movements and behaviors changed dramatically and then, over […] Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion. By creating and controlling increasingly complex forms of “squeezing” – including a fourth-order effect known as quadsqueezing – the team has, for the first time, made previously unreachable quantum effects experimentally accessible. Go to Source […] On November 7, 2006, a silent metallic disc hovered over Gate C17 at O’Hare International Airport, witnessed by United Airlines pilots and ground crew. When it shot upward, it punched a clean hole through the clouds. The FAA tried to bury it — until the Chicago Tribune forced it out. The post The O’Hare […] When you’re looking for signs of extraterrestrial intelligence, it helps to know what you’re looking for and to go about it in the most efficient way. But work so far has generally not done so, writes Benjamin Zuckerman, an astrophysicist and emeritus professor in the Department of Physics & Astronomy at the University of California […] As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands, but mostly dwelt with the nymph Calypso on her island. We can imagine that his wife, Penelope, would have asked him about that particular time. Odysseus might have replied, “It was nothing. […] Our sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers throughout the galaxy. But roughly half of sun-like stars are locked in with more than one companion star. If there are two, it’s known as a “binary” system, but in many cases there […] One of the most powerful radar systems ever launched into space has mapped the ground moving beneath one of the fastest subsiding capitals in the world: Mexico City. The findings show how quickly and reliably the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite can track real-time changes across Earth’s surface from orbit, unhindered by clouds or […] A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the universe—remain a mystery to scientists. The DAMPE (Dark Matter Particle Explorer) space telescope is tackling this phenomenon, particularly investigating the role that dark matter may play in their formation. This international mission, which includes the University of Geneva […] Researchers at the Niels Bohr Institute have broken a longstanding barrier by managing to send single photons—that can’t be copied or split and thus are secure—in the network of optical fibers we already have. This opens up a broad range of applications relying on secure quantum information. The research is published in the journal Nature […] A man allegedly entered his estranged wife’s home and sparked an explosion that ultimately killed him; several NYPD officers responding to the domestic disturbance were also injured Go to Source Measurement of nuclear reactions at record-low energies opens new pathways for astrophysics researchAn international research team has achieved an important milestone for astrophysics at GSI/FAIR in Darmstadt: In the CRYRING@ESR storage ring, scientists were able to measure nuclear reactions at extremely low energies for the first time, mirroring the conditions inside stars. This novel experimental approach lays the foundation for decoding the formation of elements in the […] Scientists at Heriot‑Watt University have demonstrated in a world-first, that light can be used to control every aspect of how electromagnetic waves oscillate, opening new technological frontiers. Researchers working in photonics, the science of light, have discovered a new way to control “polarization,” a key property of light that plays a crucial role in the […] In thermodynamics, an “adiabatic process” is a system change that transfers no heat in or out of the system. Any and all energy change in that system are therefore accomplished by doing work on the system, work being action that moves matter over a distance. (An example is a bicycle tire pump or lifting a […] Laser sail propulsion is an idea that won’t go away. By aiming powerful Earth-based lasers at tiny spacecraft with light sails, tiny spacecraft can be accelerated to near-relativistic speeds without carrying fuel or an energy source, and without carrying any kind of propulsion system at all. There are clear advantages to this idea, if it […] |
