• China’s Quantum Satellite Enables First Totally Secure Long-Range Messages

    In the middle of the night, invisible to anyone but special telescopes in two Chinese observatories, satellite Micius sends particles of light to Earth to establish the world’s most secure communication link. Micius is the world’s first quantum communications satellite and has, for several years, been at the forefront of quantum encryption. Scientists have now reported using this technology to reach a major milestone: long-range secure communication you could trust even without trusting the satellite it runs through.

  • Critical Minerals in U.S. Waters

    For centuries, people have crossed oceans in search of valuable minerals. In recent times, though, increasing attention has been paid to the oceans themselves for their mineral potential, especially rock formations on the seafloor. American researchers are focusing primarily on the U.S. Exclusive Economic Zone, or EEZ. This region extends 200 miles from a country’s shoreline and gives the country control over the exploration and exploitation of marine resources in that area.

  • Norway Pulls Its Coronavirus Contacts-Tracing App after Privacy Watchdog’s Warning

    One of the first national coronavirus contacts-tracing apps to be launched in Europe is being suspended in Norway after the country’s data protection authority raised concerns that the software, called “Smittestopp,” poses a disproportionate threat to user privacy — including by continuously uploading people’s location. Natasha Lomas writes in Tech Crunch that following a warning from the watchdog Friday, the Norwegian Institute of Public Health (FHI) said today it will stop uploading data from tomorrow — ahead of a June 23 deadline when the DPA had asked for use of the app to be suspended so that changes could be made. It added that it disagrees with the watchdog’s assessment but will nonetheless delete user data “as soon as possible.”

  • Common Drug Reduces Coronavirus Deaths, Scientists Report

    In an unexpected glimmer of hope amid an expanding pandemic, scientists at the University of Oxford said on Tuesday that an inexpensive and commonly available drug reduced deaths in patients with severe Covid-19, the illness caused by the coronavirus. Benjamin Mueller and Roni Caryn Rabin write in the New York Times that if the finding is borne out, the drug, a steroid called dexamethasone, would be the first treatment shown to reduce mortality in the sickest patients and may save hundreds of thousands of lives, eventually even millions, altering the course of the pandemic.

  • How Antibodies from Llamas May Lead to COVID-19 Treatment

    Scientists hope the special antibodies that llamas make can be directed against SARS-CoV-2 to help find our way out of the pandemic. Rockefeller University says that humans, too, make antibodies against SARS-CoV-2, and many groups are working on developing treatments based on them. Llama antibodies, however, come in a simpler design than their human counterparts. “For reasons that we don’t really understand, these animals make this variant of antibody that just has fantastic properties,” says Michael P. Rout, a structural biologist at Rockefeller. “It contains the good disease-recognizing parts of a human antibody, packed into a condensed warhead.”

  • Ensuring Complex Programs Are Bug-Free without Testing

    A team of researchers have devised a way to verify that a class of complex programs is bug-free without the need for traditional software testing. Called Armada, the system makes use of a technique called formal verification to prove whether a piece of software will output what it’s supposed to. It targets software that runs using concurrent execution, a widespread method for boosting performance, which has long been a particularly challenging feature to apply this technique to.

  • U Nevada-Reno’s programs Designated Center of Academic Excellence in Cyber Defense (CAE-CD)

    The National Security Agency (NSA) and the Department of Homeland Security (DHS) co-sponsor Centers for Academic Excellence in Cyber Defense (CAE-CD). The aim of the program is to ensure cyber defense professionals graduate from institutions of higher education with theoretical and hands-on experience in cybersecurity. After a rigorous review process, the University of Nevada-Reno’s B.S. in computer science with a minor in cybersecurity was recently designated a CAE-CD.

  • DHS CBP Selects JEOL Mass Spectrometers for Five Labs

    JEOL USA has been awarded a contract by the U.S. Department of Homeland Security Customs and Border Protection (DHS-CBP) for five JEOL AccuTOF-DART Direct Analysis in Real Time, Time-of-Flight Mass Spectrometers. The AccuTOF-DART systems will be used by CBP scientists as a non-destructive, rapid means to analyze many types of forensic samples including drugs, suspected controlled substances, unknown substances, and general organic materials.

  • Ensuring Safety of Migrants at the U.S. Borders

    Every day, undocumented migrants attempt to enter the U.S. between the ports of entry, specifically at our southwest border. Oftentimes, they face life-threatening circumstances. They are miles away from shelter, food, and water; exposed to harsh terrain and drastic changes in temperature; and lack the means to receive help if they need it. To better monitor migrant activity and provide life-saving aid when needed, ICE and DHS S&T collaborated to implement the Missing Migrants Program.

  • Research Integrity: Why We Should Trust Registered Clinical Trials

    In a time when we have to rely on clinical trials for COVID-19 drugs and vaccines, a new study brings good news about the credibility of registered clinical trials.

  • Breakthrough for Foot-and-Mouth Disease Vaccine

    When it comes to livestock, foot-and-mouth disease (FMD) is probably the most devastating picornavirus on the planet. FMD is a serious and economically devastating livestock disease. Foot-and-mouth disease virus (FMDV), the virus causing FMD, is extremely contagious and afflicts animals with cloven hooves like cows, pigs, sheep and deer.

  • From ocean waves to electricity: clean power for our planet

    The prevailing wisdom for wave energy capture has been to construct a large installation offshore, a few kilometers in the middle of the sea. But, says one expert, that’s expensive and unreliable. Offshore waves can reach tsunami-like heights that can pulverize the equipment, so few insurance companies have been willing to cover these kinds of installations and, if they do, it’s at a high cost. There is a less expensive, safer alternative: Installing “floaters” on existing manmade structures – piers, jetties and breakwaters – and putting the main energy-creating equipment with its sensitive computers and generators on land.

  • High-Tech Surveillance Amplifies Police Bias and Overreach

    Local, state and federal law enforcement organizations use an array of surveillance technologies to identify and track protesters, from facial recognition to military-grade drones. Police use of these national security-style surveillance techniques – justified as cost-effective techniques that avoid human bias and error – has grown hand-in-hand with the increased militarization of law enforcement. Extensive research, including my own, has shown that these expansive and powerful surveillance capabilities have exacerbated rather than reduced bias, overreach and abuse in policing, and they pose a growing threat to civil liberties.

  • Global Glacier Melt Raises Sea Levels, Depletes Once-Reliable Water Source

    The melting of glaciers and ice caps in places as diverse as the Himalayas and Andes mountain ranges, the Svalbard island group and the Canadian Arctic Archipelago has the dual effect of raising global sea levels and depleting freshwater resources that serve millions of people around the world.

  • Rise of Heat-Trapping Carbon Dioxide in the Atmosphere Unabated

    Atmospheric carbon dioxide measured at Mauna Loa Observatory reached a seasonal peak of 417.1 parts per million for 2020 in May, the highest monthly reading ever recorded. “Progress in emissions reductions is not visible in the CO2 record,” said one expert. “We continue to commit our planet - for centuries or longer - to more global heating, sea level rise, and extreme weather events every year.”
