Published Double locked: Polymer hydrogels secure confidential information
(via sciencedaily.com) The development of highly secure but simple and inexpensive encryption technology for the prevention of data leaks and forgeries is decidedly challenging. A research team has now introduced a 'double lock' based on thermoresponsive polymer hydrogels that encrypts information so that it can only be read at a specific window in temperature and time.
Published A security technique to fool would-be cyber attackers
(via sciencedaily.com) Researchers developed a technique that effectively protects computer programs' secret information from memory-timing side channel attacks, while enabling faster computation than other security schemes.
Published Galaxy collision creates 'space triangle' in new Hubble image
(via sciencedaily.com) A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA's Hubble Space Telescope.
Published Future gravitational wave detector in space could uncover secrets of the Universe
(via sciencedaily.com) New research has shown that future gravitational wave detections from space will be capable of finding new fundamental fields and potentially shed new light on unexplained aspects of the Universe.
Published Saturn’s high-altitude winds generate an extraordinary aurorae, study finds
(via sciencedaily.com) Space scientists have discovered a never-before-seen mechanism fueling huge planetary aurorae at Saturn.
Published Satellites and light reflections help researchers spot coastal plastic waste
(via sciencedaily.com) Geospatial scientists have found a way to detect plastic waste on remote beaches that are not visible in conventional satellite images, bringing us closer to global monitoring options.
Published The power of chaos: A robust and low-cost cryptosystem for the post-quantum era
(via sciencedaily.com) Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers.
Published How big does your quantum computer need to be?
(via sciencedaily.com) Researchers decided to explore two very different quantum problems: breaking the encryption of Bitcoin and simulating the molecule responsible for biological nitrogen fixation. They describe a tool they created to determine how big a quantum computer needs to be to solve problems like these and how long it will take.
Published New control technique uses solar panels to reach desired Mars orbit
(via sciencedaily.com) Aerospace engineers have developed a way to use articulated solar panels to steer the satellite during aerobraking, reducing the number of passes needed, resulting in potential savings in propellant, time, and money.
Published Hubble finds a black hole igniting star formation in a dwarf galaxy
(via sciencedaily.com) Often portrayed as destructive monsters that hold light captive, black holes take on a less villainous role in the latest research from NASA's Hubble Space Telescope. A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up. The black hole is apparently contributing to the firestorm of new star formation taking place in the galaxy. The dwarf galaxy lies 30 million light-years away, in the southern constellation Pyxis.
Published Being in space destroys more red blood cells
(via sciencedaily.com) Original source A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a new study.
Published New insights into seasons on a planet outside our solar system
(via sciencedaily.com) Imagine being in a place where the winds are so strong that they move at the speed of sound. That's just one aspect of the atmosphere on XO-3b, one of a class of exoplanets (planets outside our solar system), known as hot Jupiters. The eccentric orbit of the planet also leads to seasonal variations hundreds of times stronger than what we experience on Earth.
Published Rugby ball-shaped exoplanet discovered
(via sciencedaily.com) With the help of the CHEOPS space telescope, an international team was able to detect the deformation of an exoplanet for the first time. Due to strong tidal forces, the appearance of the planet WASP-103b resembles a rugby ball rather than a sphere.
Published NASA's Webb Telescope reaches major milestone as mirror unfolds
(via sciencedaily.com) Original source NASA's James Webb Space Telescope team fully deployed its 21-foot, gold-coated primary mirror, successfully completing the final stage of all major spacecraft deployments to prepare for science operations.
Published Sunshield successfully deploys on NASA's next flagship telescope
(via sciencedaily.com) The James Webb Space Telescope team has fully deployed the spacecraft's 70-foot sunshield, a key milestone in preparing it for science operations.
Published NASA's Webb telescope launches to see first galaxies, distant worlds
(via sciencedaily.com) NASA's James Webb Space Telescope launched Dec. 25 from Europe's Spaceport in French Guiana, South America. The Webb observatory's mission is to seek the light from the first galaxies in the early universe and to explore our own solar system, as well as planets orbiting other stars, called exoplanets.
Published IT security: Computer attacks with laser light
(via sciencedaily.com) Computer systems that are physically isolated from the outside world (air-gapped) can still be attacked. This is demonstrated by IT security experts. They show that data can be transmitted to light-emitting diodes of regular office devices using a directed laser. With this, attackers can secretly communicate with air-gapped computer systems over distances of several meters. In addition to conventional information and communication technology security, critical IT systems need to be protected optically as well.
Published Are black holes and dark matter the same?
(via sciencedaily.com) Astrophysicists suggest that primordial black holes account for all dark matter in the universe.
Published Real-world study shows the potential of gait authentication to enhance smartphone security
(via sciencedaily.com) A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential crime.
Published Closest pair of supermassive black holes yet
(via sciencedaily.com) Astronomers have revealed the closest pair of supermassive black holes to Earth ever observed. The two objects also have a much smaller separation than any other previously spotted pair of supermassive black holes and will eventually merge into one giant black hole.
