Detecting landmines can be a challenging and slow process. Detecting them from a moving vehicle would make the process more speedy, but at the expense of accuracy.

At the Optical Society’s (OSA) Laser Congress, held 29 September—3 October 2019 in Vienna, Austria, researchers from the University of Mississippi, U.S.A., will report a new laser-based sensor that effectively detects buried objects even while the detector is in motion. This new device offers a significant improvement over existing technologies, which cannot be operated on the go and lose accuracy in the presence of external sources of sound or vibration.

Laser Doppler vibrometers (LDVs) combined with vibration excited in the ground have shown promise for detecting landmines and other buried objects, but their sensitivity to environmental vibrations mean they must be operated from a special stable platform. The device, called a Laser Multi Beam Differential Interferometric Sensor (LAMBDIS), provides comparable detection capabilities but is far less sensitive to motion, allowing it to be used aboard a moving vehicle.

On a recent afternoon at the Johnson Space Center, Bill Paloski, Ph.D., Director of NASA’s Human Research Program (HRP), commented on HRP’s mission to protect the health and safety of astronauts. He reflected on some of the human hazards of space, including radiation, isolation and confinement, distance from Earth, altered gravity, and hostile/closed environments.

“We still have a lot to learn about these hazards,” says Paloski. “For instance, how long does it take for space radiation to damage the human body? When you’re isolated, and can’t get home or talk to your family, how long can you stay positive? NASA’s Human Research Program exists to ensure the safety of brave people who are navigating unfamiliar territory in very stressful conditions. We need this program and its research teams to develop strategies to protect our explorers and pioneers who represent the front line of our nation’s space program.”

Paloski’s dedication to improving the lives of this “front line” has provided benefit to other sectors of the federal government, including those who serve the nation in high-risk missions and those in our military services. In recognition of these benefits, Paloski recently received the prestigious Robert M. Yerkes Award for significant contributions to military psychology by a non-psychologist.

TOKYO (Reuters) — Inspired by new ultra-thin solar panels developed for satellites, a project led by Toyota Motor Corp is experimenting with a sun-powered Prius that it hopes will one day require no plugging in.

In the Japanese government-funded demonstration project, Toyota engineers fitted solar panels designed by Sharp Corp to the hood, roof, rear window and spoiler to see how much juice the sun can generate.

The electricity from the panels goes directly to the drive battery, so the Prius can charge while moving or when parked.

SAN JOSE DEL GUAVIARE, COLOMBIA — Cerafín Méndez was out drinking one night when a fight broke out with his neighbor. The next day, three FARC soldiers came for him, bound his hands, and led him away.

That was the last time his family would see him alive.

LUXEMBOURG—( BUSINESS WIRE )—SES announced today that it has selected SpaceX as a launch partner to deliver its next-generation Medium Earth Orbit (MEO) satellite constellation into space on board Falcon 9 rockets from Cape Canaveral. The two companies have disrupted the industry in the past when SES became the first to launch a commercial GEO satellite with SpaceX, and later as the first ever payload on a SpaceX reusable rocket. Their next launch, in 2021, will be another one for the records as the revolutionary terabit-scale capabilities of SES’s O3b mPOWER communications system disrupt the industry again.

The global O3b mPOWER system comprises an initial constellation of seven high-throughput, low-latency MEO satellites, each capable of generating thousands of electronically-steered beams that can be dynamically adjusted to serve customers in various markets including telecom and cloud, communications-on-the-move and government. O3b mPOWER also will include a variety of intelligent, application-specific Customer Edge Terminals integrated with SES’s terrestrial network and dynamically optimised using the recently announced Adaptive Resource Control (ARC) software system, further boosting O3b mPOWER’s market-leading flexibility.

After what has been a summer of “crippling ransomware attacks,” there has now been some respite courtesy of the city of New Bedford, Massachusetts, which has proven that the playing field can be levelled. The city was hit back in July, with its data held hostage, ransomed for more than $5 million in bitcoin. But as the attackers waited for their payment, the city’s law enforcement agencies and technology teams had other ideas.

No types of organisations are immune from these types of attacks these days,” Mayor Jon Mitchell told reporters. The city government, he said, had been taking steps to strengthen our defences—but any network is only one keyword click away from an attack. Thankfully, he acknowledged, “the attack could have been much worse.” It hit on the July 4 holiday when many systems were shut down.

“The attack was a variant of the RYUK virus,” Mitchell confirmed. “The victim needs to make a ransom payment to acquire the decryption key from the attacker.” The attack did not affect all systems or disrupt all services, and on the return to work on July 5, the city kept systems turned off as they isolated the attack.

When practical quantum computing finally arrives, it will have the power to crack the standard digital codes that safeguard online privacy and security for governments, corporations, and virtually everyone who uses the Internet. That’s why a U.S. government agency has challenged researchers to develop a new generation of quantum-resistant cryptographic algorithms.

Many experts don ’t expect a quantum computer capable of performing the complex calculations required to crack modern cryptography standards to become a reality within the next 10 years. But the U.S. National Institute of Standards and Technology (NIST) wants to stay ahead by getting new cryptographic standards ready by 2022. The agency is overseeing the second phase of its Post-Quantum Cryptography Standardization Process to narrow down the best candidates for quantum-resistant algorithms that can replace modern cryptography.

“Currently intractable computational problems that protect widely-deployed cryptosystems, such as RSA and Elliptic Curve-based schemes, are expected to become solvable,” says Rafael Misoczki, a cryptographer at the Intel Corporation and a member of two teams (named Bike and Classic McEliece) involved in the NIST process. “This means that quantum computers have the potential to eventually break most secure communications on the planet.”

After WW II, a government program aimed to find a peaceful use for nuclear power. And thus, the atomic garden was born.
