James Webb Space Telescope: Launch of world"s most complex observatory will rest on a nail-biting knife edge
When the immense sound of the Ariane 5 rocket rumbles across Europe's spaceport in French Guiana, it will signal the end of a journey decades in the making. Perched atop the rocket will be the James Webb Space Telescope (JWST), the most sophisticated.....»»
Focusing sound vibrations precisely can knock over one Lego minifig among many
The key is a signal processing technique that is akin to ventriloquism. Enlarge / Brian Anderson's experiments with Lego minifigs led to the development of an interactive museum exhibit in Switzerland. (credit: Brian Anderson).....»»
Apple and Google"s Mobile Duopoly Likely To Face UK Antitrust Action
The U.K.'s antitrust watchdog has given the clearest signal yet that interventions under an upcoming reform of the country's competition rules will target tech giants Apple and Google -- including their duopolistic command of the mobile market, via i.....»»
New antennas in the Australian hinterland reduce background noise in search for 13-billion-year-old signal
The early universe was dark, filled with a hot soup of opaque particles. These condensed to form neutral hydrogen which coalesced to form the first stars in what astronomers call the epoch of reionisation (EoR)......»»
Study reveals how bacterial pathogen adapts to nutritional stress
In order to cause disease, the human pathogen Staphylococcus aureus must adapt to the changing host environment. Many of these adaptations are mediated through two-component signal transduction systems (TCSs) that coordinate gene expression in respon.....»»
Shudder"s claustrophobic "Death Valley" trailer is a hectic underground monster romp
A distress signal from a compound? People trapped underground? Armed soldiers facing off against an unknown threat?Tapping into the popularity of films like Resident Evil and Doom is Shudder's upcoming movie Death Valley, a story about a couple of hi.....»»
Qualcomm wants you to know it powers the world’s best camera phones
Qualcomm has developed some of the world's most advanced Image Signal Processors (ISPs) for smartphones. But how many people actually know about this?.....»»
FAA, FCC Are Making "Progress" on 5G Signal Woes
U.S. aviation regulators are having "very productive discussions" with the Federal Communications Commission and the telecommunications industry over concerns that 5G technology could interfere with aircraft equipment, an official said. From a report.....»»
Simultaneous TES readout at level of Athena-like telescopes
Scientists at SRON Netherlands Institute for Space Research have simultaneously read out the signal of 37 TES pixels at a resolution of 2.2 eV for X-rays (6 keV). It is the first time that a simultaneous readout fulfills the requirements for future s.....»»
Genetic contact tracing could help curb TB
The novel use of genetic contact tracing to identify the source of a bovine tuberculosis outbreak could signal a new approach in managing the disease, a study suggests......»»
Sending up the bat signal on forest use by endangered species
Deep in an Indiana forest, a team of scientists skulked atop hillsides after dark. Carrying radios and antennas, they fanned out, positioning themselves on opposite ridges to wait and listen. Their quarry? Endangered Indiana bats and threatened north.....»»
A Strange Radio Signal Was Just From Earth, Not Aliens
Astronomers with the Breakthrough Listen project scan the sky for signs of extraterrestrial life, but a promising lead turned out to be a false alarm......»»
Promising-looking SETI signal turns out to be of human origin
Space junk may look like a supernova as SETI researchers struggle with a signal. Enlarge / Proxima Centauri, the closest star to Earth aside from the Sun. (credit: ESA, Hubble, and NASA) Modern human society has been making it.....»»
Breakthrough Listen project releases analysis of previously detected signal
An intriguing candidate signal picked up last year by the Breakthrough Listen project has been subjected to intensive analysis that suggests it is unlikely to originate from the Proxima Centauri system. Instead, it appears to be an artifact of Earth-.....»»
The highest amplification in tiny nanoscale devices
A team of researchers from the University of Florida, led by Dr. Philip Feng, in collaboration with Prof. Steven Shaw in Florida Institute of Technology, has now demonstrated extremely high-efficient mechanical signal amplification in nanoscale mecha.....»»
Quantum-encrypted information transmitted over fiber more than 600 kilometers long
By implementing a new signal stabilization technique, researchers were able to achieve secure quantum communication over a record 605 kilometers of fiber using the twin-field quantum key distribution (QKD) protocol. The new demonstration paves the wa.....»»
One of the first models to capture dynamics of confined cell movement
The process of normal cell division in the human body is quite simple: start dividing in response to a signal, such as a wound, and stop when enough cells have been produced and the skin is healed. But cancerous cells ignore the stop signs. They grow.....»»
Predicting famines using rainfall season start
The first rains that signal the beginning of the growing season kick off a flurry of activities in rural, agricultural communities. Farmers decide when to plant, how much labor to allocate, how many resources to devote to that season's crop and so on.....»»
We found a mysterious flashing radio signal from near the centre of the galaxy
In early 2020, we detected an unusual radio signal coming from somewhere near the center of our galaxy. The signal blinked on and off, growing 100 times brighter and dimmer over time......»»
What Really Motivated the Breaches of Twitch and Epik?
The Washington Post explores recent breaches at Twitch and Epik — and asks whether they really signal an upsurge in "hacktivism": The perpetrators of these hacks are distancing themselves from financially driven cybercriminals and ransomware g.....»»
