• Iran Vows to Continue Nuclear Activities

    Iranian President Ebrahim Raisi has said Iran will continue nuclear development activities as talks to revive Tehran’s nuclear deal with world powers remain stalled. The nuclear deal collapsed four years ago when former President Donald Trump withdrew the United States from the agreement, allowing Iran to vastly expanded its nuclear work.

  • The Future of 5G+ Infrastructure Could Be Built Tile by Tile

    Currently 5G+ technologies rely on large antenna arrays that are typically bulky and come only in very limited sizes, making them difficult to transport and expensive to customize. Researchers have developed a novel and flexible solution to address the problem. Their additively manufactured tile-based approach can construct on-demand, massively scalable arrays of 5G+‐enabled smart skins with the potential to enable intelligence on nearly any surface or object.

  • How Ukraine Has Defended Itself Against Cyberattacks – Lessons for the U.S.

    In 2014, as Russia launched a proxy war in Eastern Ukraine and annexed Crimea, and in the years that followed, Russian hackers hammered Ukraine. The cyberattacks went so far as to knock out the power grid in parts of the country in 2015. Russian hackers stepped up their efforts against Ukraine in the run-up to the 2022 invasion, but with notably different results. Those differences hold lessons for U.S. national cyber defense.

  • Curbing Explosive Weapons in Populated Areas

    The Ukrainian city of Mariupol is one of the latest examples of a populated area that has been turned to rubble by the relentless use of heavy explosive weapons. Destroyed cities and towns in Yemen, Ethiopia, and Syria, among others, provide other examples. An international agreement under negotiation at the United Nations this week seeks to reduce harm to civilians by curbing the use of heavy explosive weapons in cities, towns and villages.

  • Californians Living with Handgun Owners More Than Twice as Likely to Die by Homicide

    Californians who didn’t own handguns but lived with handgun owners were more than twice as likely to die by homicide compared with those living in gunfree homes.

  • Tactical Tunneling to Help Military Operations, Rescue Missions

    New tactical tunneling technologies show the feasibility of rapidly constructing tactical tunnel networks that enable secure, responsive resupply in denied environments. These networks could provide infrastructure for logistics support, such as pre-positioning supplies in advance of an operation or providing ongoing resupply as troops move through a contested area. The ability to rapidly bore tactical tunnels could also be helpful in rescue missions.

  • Cyberattacks Have Yet to Play a Significant Role in Russia’s Battlefield Operations in Ukraine – Cyberwarfare Experts Explain the Likely Reasons

    Since the latter half of 2021 analysts offered contrasting predictions about the role cyberspace would play in an armed conflict. These predictions capture an ongoing debate about whether conflict in cyberspace is destined to supplant conventional conflict or exacerbate it. As the war has evolved, it’s clear that analysts on both sides of the debate got it wrong.

  • Russia's Failure Leads to the Next Phase of the Ukraine War: Interview

    Russia’s failure to achieve its initial objectives in Ukraine – and achieve them quickly and cheaply — has led to a rethinking in Russia about the next phase of the war. “You can’t bomb urban areas into submission. You can’t even bomb entrenched soldiers into submission. Military history proves that you have to eventually close the distance and take what you want,” say a military expert. “[Russia] would like to get reinforcements and resupply the southeastern fight. If they really want that objective of connecting the separatist areas [to Crimea] and pushing back the Ukrainian military and [that] being what they’re able to negotiate as their win, that’s still a tough fight that [they will] have to close the distance for.”

  • China Has Capability to Use Space for Military Purposes: Experts

    Military analysts say that China now has the technology, hardware and know-how to coordinate a war from space. The Chinese military would most likely use military technology in space to seek control in the disputed East and South China seas and fend off challenges on the high seas of the Western Pacific just beyond China’s near seas, analysts say.

  • European Neo-Nazi Group Exports Anti-Semitism Across Scandinavia, Beyond

    Sweden’s Nordic Resistance Movement held 185 “combat training” sessions in 2020 and has served as inspiration for American racially or ethnically motivated violent extremists. The Nordic Resistance is Scandinavia’s most dangerous far-right extremist group, actively spreading its hate message abroad.

  • The Military Is Making Progress in Its Counter-Extremism Efforts, but Gaps Remain

    DOD released its report on countering extremist activity in the ranks. Andrew Mines writes that the report is timely, as data from research by different organizations provide multiple metrics that show a relatively small but growing problem of extremism in the military. “Today, the U.S. faces an extremist threat that is increasingly mainstream and harder to counter with traditional prevention tools. The federal government is already undergoing a sea change in its own approach, and the military has shown that it isn’t shying away from the problem either,” he writes.

  • DIY Innovations for Bomb Squads

    Bomb-squad members must effectively employ critical thinking and problem-solving skills while working in stressful, potentially life-threatening situations. DHS S&T notes that bomb technicians’ ability to expect the unexpected and adjust accordingly has created a consistent pipeline of do-it-yourself (DIY) inventions to solve everyday issues they face, and the S&T works to validate these innovations.

  • Food Security During a Nuclear Winter

    A nuclear war would cause global blockage of the sun for several years due to injections of black carbon soot into the upper atmosphere, covering most of the planet with black clouds. This could result in less than 40 percent of normal light levels near the equator and less than 5 percent normal light levels near the poles. Research focuses on how meeting food security and nutrition in post-catastrophe conditions, which could last 15 years in some wet tropical forests.

  • DHS Sued Over Vetting Program to Collect and Data Mine

    The Electronic Frontier Foundation (EFF) the other day filed a Freedom of Information Act (FOIA) lawsuit against the Department of Homeland Security (DHS) for records about a multi-million dollar, secretive program that surveils immigrants and other foreign visitors’ speech on social media.

  • With Threats of Nuclear War and Climate Disaster Growing, America’s “Bunker Fantasy” Is Woefully Inadequate

    Faced with a Congress unwilling to fund large-scale sheltering measures — although in Europe and elsewhere, vast public shelters were built, the community bomb shelter was almost universally rejected in the U.S. as communistic — the Kennedy administration decided instead to encourage the private development of the individual shelter industry and to establish dedicated spaces within existing public structures.
