Why we need to adopt an abundance mindset.

Peter Diamandis shared an email blast about dire headlines that keep us on edge: the war in Ukraine, food and gasoline prices, climate change, and the neverending pandemic. Getting away from bad news is difficult, it appears, because of the way we are wired. Mass media feeds the bad far more than the good.

In his missive, Peter talks about Matt Ridley, a zoologist, who wrote and published The Rational Optimist in 2010. The book takes a profoundly optimistic view of human progress, a counterblast to the prevailing pessimism of our day. Ridley coined the phrase “moaning pessimism” to describe the current state.

Scientists from the University of California, Irvine have discovered that an injury to one part of the brain changes the connections between nerve cells across the entire brain. The new research was published this week in Nature Communications.

Every year in the United States, nearly two million Americans sustain a traumatic brain injury (TBI). Survivors can live with lifelong physical, cognitive and emotional disabilities. Currently, there are no treatments.

One of the biggest challenges for neuroscientists has been to fully understand how a TBI alters the cross-talk between different cells and brain regions.

The research uses machine learning technology to look at structural features within the brain, including in regions not previously associated with Alzheimer’s. The advantage of the technique is its simplicity and the fact that it can identify the disease at an early stage when it can be very difficult to diagnose.

Although there is no cure for Alzheimer’s disease, getting a diagnosis quickly at an early stage helps patients. It allows them to access help and support, get treatment to manage their symptoms and plan for the future. Being able to accurately identify patients at an early stage of the disease will also help researchers to understand the brain changes that trigger the disease, and support development and trials of new treatments.

The research is published in the Nature Portfolio Journal, Communications Medicine.

You can essentially bend light with your mind using the new technology.

For years, physicists have been making major advances and breakthroughs in the field using their minds as their primary tools. But what if artificial intelligence could help with these discoveries?

Last month, researchers at Duke University demonstrated that incorporating known physics into machine learning algorithms could result in new levels of discoveries into material properties, according to a press release by the institution. They undertook a first-of-its-kind project where they constructed a machine-learning algorithm to deduce the properties of a class of engineered materials known as metamaterials and to determine how they interact with electromagnetic fields.

A lightning-caused wildfire that led to an evacuation of the Kitt Peak National Observatory southwest of Tucson is 40% contained, authorities said.

More than 300 firefighters were working the wildfire Saturday. If all goes as planned, authorities said the blaze could be fully contained by next Sunday.

The wind-whipped fire started June 11 on a remote ridge on the Tohono O’odham Indian Reservation, about 8 miles (13 kilometers) southeast of Kitt Peak.

Rune Labs, a precision neurology company, has announced its StrivePD software ecosystem for Parkinson’s disease has been granted 510(k) clearance by the US Food and Drug Administration (FDA) to collect patient symptom data through measurements made by Apple Watch.

By combining powerful wearable technology and self-reported symptom information with brain imaging, electrophysiology, genetic and other clinical data, StrivePD enables a data-driven approach to care management and clinical trial design for Parkinson’s.

Longevity. Technology: With this clearance, the Rune Labs’ StrivePD app enables precision clinical care and trial participation for tens of thousands of Parkinson’s patients who already use these devices in their daily lives.

Quantum sensors can now detect signals of arbitrary frequencies thanks to a quantum version of frequency mixing—a widely used technique in electronics.

Monitoring the fissile material aboard nuclear-powered submarines is notoriously difficult. Researchers may now have a way to safeguard this weapons-grade substance.

Monitoring the fissile material aboard nuclear-powered submarines is notoriously difficult. Researchers may now have a way to safeguard this weapons-grade substance.

Last year, the United Kingdom and the United States agreed to transfer some of their nuclear-powered submarines to Australia, a country that, at that time, possessed none. On hearing the announcement, Bernadette Cogswell and Patrick Huber of Virginia Tech in Blacksburg say that they were immediately concerned as there is currently no easy way to safeguard a nuclear reactor aboard a submarine. Now, the duo has come up with a technique that could solve that problem [1]. They say that the method could be used to confirm the presence of a submarine’s nuclear core without the need for onboard monitoring.

Most naval nuclear reactors employ uranium that is highly enriched fissile uranium-235 (235U 2 3 5 U 235U), a material also used to make nuclear weapons. For land-based reactors, inspectors keep track of 235U 2 3 5 U 235U using neutrino detectors placed close to an operating core (see Feature: Neutrino Detectors for National Security). But this technique doesn’t work for the water-submerged cores in submarines at sea. It also fails for the weak signals from powered-down cores, allowing operators to subvert checks of docked submarines.
