According to the Bulletin, we’ve done nothing in the past year to make the situation any less precarious — humanity still faces not one, but two “existential threats” in the form of nuclear weapons and climate change.

While the clock remains set at 11:58, the potential of either threat to destroy humanity has increased over the past 12 months, according to the Bulletin’s 2019 statement. We must do something to alter our path.

“Though unchanged from 2018, this setting should be taken not as a sign of stability but as a stark warning to leaders and citizens around the world,” the scientists wrote. “The current international security situation — what we call the ‘new abnormal’ — has extended over two years now… Th e longer world leaders and citizens carelessly inhabit this new and abnormal reality, the more likely the world is to experience catastrophe of historic proportions.”

Nuclear fission — the physical process by which very large atoms like uranium split into pairs of smaller atoms — is what makes nuclear bombs and nuclear power plants possible. But for many years, physicists believed it energetically impossible for atoms as large as uranium (atomic mass = 235 or 238) to be split into two.

That all changed on Feb. 11, 1939, with a letter to the editor of Nature — a premier international scientific journal — that described exactly how such a thing could occur and even named it fission. In that letter, physicist Lise Meitner, with the assistance of her young nephew Otto Frisch, provided a physical explanation of how nuclear fission could happen.

It was a massive leap forward in nuclear physics, but today Lise Meitner remains obscure and largely forgotten. She was excluded from the victory celebration because she was a Jewish woman. Her story is a sad one.

Alcatraz holds many forgotten secrets, but one has been discovered: High-tech radar and laser scans have uncovered a hidden military traverse underneath the infamous penitentiary, according to new research.

A team of researchers from Binghamton University, State University of New York used terrestrial laser scans, ground-penetrating radar data, and georectifications (the process of taking old digitized maps and linking them to a coordinate system so that they can be accurately geolocated in 3D space) to locate and assess the historical remains beneath the former recreation yard of the Alcatraz penitentiary, according to a press release.

The attack threatens users with location-tracking, DoS, fake notifications and more.

Privacy-breaking flaws in the 4G and 5G mobile protocols could allow attackers to intercept calls, send fake amber alerts or other notifications, track location and more, according to a research team from Purdue University and the University of Iowa.

In a paper presented at Mobile World Congress in Barcelona this week, the researchers explained that the issues arise from weaknesses in the cellular paging (broadcast) protocol. They started with the fact that when a mobile device is in its idle, low-power state, it will conserve battery life partly by polling for pending services only periodically.

Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published February 28 in the journal Cell. A single injection of nanoparticles in the mice’s eyes bestowed infrared vision for up to 10 weeks with minimal side effects, allowing them to see infrared light even during the day and with enough specificity to distinguish between different shapes. These findings could lead to advancements in human infrared vision technologies, including potential applications in civilian encryption, security, and military operations.

Injectable photoreceptor-binding nanoparticles with the ability to convert photons from low-energy to high-energy forms allow mice to develop infrared vision without compromising their normal vision and associated behavioral responses.

Researchers have been on the hunt for a superconductor that would work at around room temperature, which they consider to be 25 degrees Celsius (77 degrees Fahrenheit) — and according to the patent application, Navy researcher Salvatore Cezar Pais thinks he’s figured it out.

Pais’ application describes a wire consisting of a metal coating over an insulator core. An electromagnetic coil surrounds the wire, and when activated by a pulsed current, this coil causes a vibration that allows the wire to act as a superconductor at room temperature, according to the application.

Many people in Hawaii faced that very question on Jan. 13, 2018. That morning, at 8:07 a.m. local time, the Hawaii Emergency Management Agency sent out an alert advising residents to seek shelter from an incoming ballistic missile.

Unbeknownst to just about everyone at the time, however, the alert was a false alarm. Even the operator who sent out the alarm, issued over text messages and on TV and radio stations, thought it was real. But it was accidentally sent out during a shift change, and the incoming operator didn’t realize that the alert was part of a preparedness drill.

An erroneous alert about a nuclear attack was sent to Hawaii residents. The ensuing confusion and hysteria revealed that Americans are not prepared.
