Lawrence Livermore creates 100 terawatt laser milestone
In a rapid blast at Lawrence Livermore National Lab a laser pulse reached at least 100 terawatts lasting a fraction of a second. Lab officials say the achievement inaugurates a new era in laser research and could lead to a petawatt laser later this year, vastly increasing energy concentration for high speed, high temperature experiments. Campbell, the laser chief, notes the burst consumes far more energy than the US grid during the moment and doubts military use due to brief duration.

Quiet skies need freedom from radio interference
Astronomers warn rising radio use from phones and satellites blocks view of the universe. Rogier Windhorst of Arizona State University says parts of the cosmos will remain hidden from radio observation as mobile networks grow. Clint Jones of the Very Large Array notes coordination is needed to clear airwaves for telescopes amid hundreds of planned low Earth orbit satellites.

Stress damages brain and memory in trauma victims
Severe stress and trauma may shrink the hippocampus, harming learning and memory. Veterans with post trauma symptoms show about 8 percent smaller right hippocampus than unaffected vets, with verbal memory tests showing lower scores. Experts caution that the hippocampus is key to holding information briefly before it becomes lasting memory.

Brain Perception Teaches Instant Liking Bias In Minds
Researchers report the brain assigns value to sights and sounds at first perception. Tests show immediate unconscious evaluations even for unfamiliar words. mere exposure rarely removes the initial liking or disliking. Leading psychologists note that nothing feels truly neutral, as judgments persist unless actively countered.

First Impressions and a New State of Matter
Scientists spar over Bargh's automatic judgment claim while Seattle physicists report a new state of matter near absolute zero. Researchers cite unconscious biases in perception, and Wieman notes speculative applications in lasers, nano tech, clocks, and analysis as decades of exploration begin.

Rapid judgments at first glance reveal hidden attitudes
Experiments by Jonathan Bargh and Russell Faso show that quick automatic judgments form within a few hundredths of a second when people view paired words or images. They press like or dislike. slower responses occur when the two items provoke opposing evaluations, with unaided awareness.

Evolution and technology diverge from biology in parallel ways
American biologist Stuart Kauffman argues in the McKinsey Quarterly that the Cambrian explosion’s rapid diversification mirrors how technology evolves. After a key innovation, broad experimentation occurs, then branching slows and few variants persist, a pattern also seen in ecosystems and economies.
