Researchers have developed a new 3D method that can be used to track fast-moving objects at unprecedented high speeds. The real-time tracking approach, which is based on single-pixel imaging, could be used to improve autonomous driving, industrial inspection and security surveillance systems.
LOS ANGELES — Redwire announced a contract June 17 to serve as prime mission integrator for a DARPA satellite with a novel propulsion system for very low Earth orbit (VLEO).
SabreSat, Redwire’s VLEO satellite for government intelligence, surveillance and reconnaissance missions, will house “air-breathing” electric propulsion systems being developed through DARPA’s Otter program.
Cybersecurity researchers have disclosed that the LightSpy spyware recently identified as targeting Apple iOS users is in fact a previously undocumented macOS variant of the implant.
The findings come from both Huntress Labs and ThreatFabric, which separately analyzed the artifacts associated with the cross-platform malware framework that likely possesses capabilities to infect Android, iOS, Windows, macOS, Linux, and routers from NETGEAR, Linksys, and ASUS.
“The Threat actor group used two publicly available exploits (CVE-2018–4233, CVE-2018–4404) to deliver implants for macOS,” ThreatFabric said in a report published last week. “Part of the CVE-2018–4404 exploit is likely borrowed from the Metasploit framework. macOS version 10 was targeted using those exploits.”
In March, the United States reported its first detection of the highly pathogenic H5N1 avian influenza in dairy cattle, with outbreaks spreading to nine states by May. The transmission method among cattle remains unclear. However, a study published in the journal Nature Communications revealed that a similar H5N1 strain, subtype clade 2.3.4.4b, which previously caused an outbreak in farmed mink in 2022, was capable of airborne transmission to a small group of ferrets.
This is the first time that a member of the group of H5N1 clade 2.3.4.4b viruses has been shown to exhibit this ability. According to the Penn State researchers who led the study, the findings suggest these viruses are evolving to infect mammals and with potentially increased risk to humans.
“While there is no evidence that the strain of H5N1 that is presently affecting dairy cattle is capable of airborne transmission, our study suggests that another member of this family of viruses has evolved some degree of airborne transmissibility,” said Troy Sutton, associate professor of veterinary and biomedical sciences, Penn State, and corresponding author on the paper. “This finding underscores the importance of continued surveillance to monitor the evolution of these viruses and their spillover into other mammals, including humans.”
To overcome these obstacles, the research team developed a novel pulse irradiation synthesis method that achieves both a low processing temperature and an ultra-short reaction time, surpassing the capabilities of conventional techniques.
With the new method for preparing metal sulfide thin films at low temperatures, these detectors can now achieve higher performance on suitable flexible substrates. This creates exciting possibilities for thermal imaging applications in security monitoring, fire detection, military surveillance, and other fields.
Additionally, the photothermoelectric effect allows for the conversion of invisible infrared light into electrical signals, paving the way for applications in high-speed communications and optical signal processing.
Underwater recon and attack drones are about to enter war zones.
Australia has unveiled ‘Ghost Shark’, an underwater drone that is capable of surveillance, intelligence collection and attacking enemy targets. The U.S. has a ‘Monster Manta’ that can carry a range of payloads, carry out long-range missions. Countries around the world are developing unmanned underwater vehicles for the next war at sea. What about India?

Scientists champion global genomic surveillance using the latest technologies and a ‘One Health’ approach to protect against novel pathogens like avian influenza and antimicrobial resistance, catching epidemics before they start.
The COVID-19 pandemic turned the world upside down. In fighting it, one of our most important weapons was genomic surveillance, based on whole genome sequencing, which collects all the genetic data of a given microorganism. This powerful technology tracked the spread and evolution of the virus, helping to guide public health responses and the development of vaccines and treatments.
But genomic surveillance could do much more to reduce the toll of disease and death worldwide than just protect us from COVID-19. Writing in the journal Frontiers in Science, an international collective of clinical and public health microbiologists from the European Society for Clinical Microbiology and Infectious Diseases (ESCMID) calls for investment in technology, capacity, expertise, and collaboration to put genomic surveillance of pathogens at the forefront of future pandemic preparedness.
Two piloted one-seat eVTOLs flew in formation during an exciting premiere by Jetson, opening the road for a wide range of missions in the future.
