Engineers develop terahertz imaging system capable of capturing real-time, 3D multi-spectral images
Terahertz waves can penetrate opaque materials and provide unique spectral signatures of various chemicals, but their adoption for real-world applications has been limited by the slow speed, large size, high cost and complexity of terahertz imaging s.....»»
Scientists develop high-power optic fiber laser to power nano satellites
The use of lasers in space is a reality. Even though radio waves have been the backbone of space communications for ages, the demand to convey more data, in a faster way, made these lighter, more flexible, and more secure infrared rays (invisible to.....»»
Marine heat waves affecting little penguin population
Research led by The University of Western Australia has found marine heat waves are affecting the breeding, diet and population size of little penguins along Western Australia's coast......»»
Researchers visualize energetic ion flow in fusion devices
In a burning plasma, maintaining confinement of fusion-produced energetic ions is essential to producing energy. These fusion plasmas host a wide array of electromagnetic waves that can push energetic ions out of the plasma......»»
Gravitational waves could show us the first minute of the universe
Astronomers routinely explore the universe using different wavelengths of the electromagnetic spectrum from the familiar visible light to radio waves and infrared to gamma rays. There is a problem with studying the universe through the electromagneti.....»»
Adalanche: Open-source Active Directory ACL visualizer, explorer
Adalanche provides immediate insights into the permissions of users and groups within an Active Directory. It’s an effective open-source tool for visualizing and investigating potential account, machine, or domain takeovers. Additionally, it he.....»»
Hurricane waves hitting Americas grow 20% per decade: Study
The U.S., Mexico and countries in the Caribbean are being battered by hurricane-induced ocean waves that have grown in areal size by 80% over the past 40 years, a new study has found......»»
Scientists flip around gravitational-wave data analysis: Have LIGO and Virgo detected a merger of dark-matter stars?
Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang itself. Since their first det.....»»
Department of Justice antitrust filing against Apple said to be imminent, for the fourth consecutive year
A new report claims that the US Department of Justice is in the "late stages" of investigating Apple and a wide-ranging complaint will be filed soon, but how — or if — it will all play out isn't actually clear.Apple has reportedly been under inve.....»»
Conflict in full swing: Forest bats found to avoid large areas around fast-moving wind turbines
Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense h.....»»
DriveFS Sleuth: Open-source tool for investigating Google Drive File Stream’s disk forensic artifacts
DriveFS Sleuth automates the investigation of Google Drive File Stream disk artifacts. The tool can parse the disk artifacts and build a filesystem tree-like structure enumerating the synchronized files along with their respective properties. “.....»»
Laser scarecrows could offer a sustainable solution for protecting crops from birds
Damage to crops caused by birds costs millions of dollars each year. Now, researchers from the University of Florida and the University of Rhode Island in the US are investigating the effectiveness of laser scarecrows—a high-tech solution using lig.....»»
NASA tests 3D-printed, rotating detonation rocket engine
Looking to the future, NASA is investigating several technologies that will allow it to accomplish some bold objectives. This includes returning to the moon, creating the infrastructure that will let us stay there, sending the first crewed mission to.....»»
Hubble snaps an image of dark spokes in Saturn’s rings
The Hubble Space Telescope is investigating something strange about the beautiful rings around Saturn......»»
Surf"s up: Big waves pound US West Coast
Huge surf was battering the US West Coast on Friday, with forecasters warning of more danger ahead after a rogue wave swept pedestrians off their feet and swamped a hotel......»»
A dense quark liquid is distinct from a dense nucleon liquid
Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves dissolve into a quar.....»»
Zwicky Transient Facility detects four ultracompact binaries
By investigating dwarf novae identified by the Zwicky Transient Facility (ZTF), astronomers have discovered four binary systems. The objects turned out to be eclipsing accreting ultracompact white dwarf binaries. The finding was reported in a paper p.....»»
Harnessing all-dielectric metamaterials to manipulate the polarization state of light
Polarization is one of the fundamental characteristics of electromagnetic waves. It can convey valuable vector information in sensitive measurements and signal transmission, which is a promising technology for various fields such as environmental mon.....»»
Marine heat waves: Why the East Sea experienced extreme conditions in 2021
Extreme environmental events are becoming an ever more pressing concern with the continued stresses of climate change, both on land and in the marine realm. While terrestrial heat waves tend to occur over a few days, those in the oceans often have lo.....»»
Constraining the dynamics of rotating black holes via the gauge symmetry principle
In 2015, the LIGO/Virgo experiment, a large-scale research effort based at two observatories in the United States, led to the first direct observation of gravitational waves. This important milestone has since prompted physicists worldwide to devise.....»»
