People who naturally stay up late, so-called “night owls”, are more likely to experience faster cognitive decline than those who are early risers, according to a long-term study.
Hermeus seems dead keen on fast-tracking its way to hypersonic passenger flight. Its uncrewed subsonic Quarterhorse Mark 1 prototype has completed its maiden flight in the skies over Edwards Air Force Base in California on May 21, 2025.
Hypersonic flight looks to be the flavor du jour of the aerospace world these days, which isn’t surprising. Not only is it poised to revolutionize warfare, it also has the potential to alter civilian cargo and passenger travel in ways far beyond what Concorde and its kin promised but never delivered in the 1960s.
The tricky bit is how to, pardon the pun, get it all off the ground. Since its founding in 2018, Hermeus has been pursuing a novel development strategy. Instead of the conventional approach of working directly on a final aircraft preceded by, perhaps, a flying prototype or two that approximate the performance of the ultimate aircraft, the company has been working on highly specialized prototypes designed to specifically test various systems without any pretense of being anything like a hypersonic plane.

Dopamine, a small molecule derived from the amino acid tyrosine, plays a significant role in regulating multiple essential brain functions, including movement, mood and motivation as well as multiple cognitive functions, including attention and memory.
Dopamine signaling in the brain is a complex process, with many mechanisms in place to accelerate or slow down dopamine’s effects. When dopamine is released from nerve cells, its efficient removal to limit signaling occurs through the activity of special proteins called “transporters,” ensuring a shorter action of dopamine in the brain.
Disruptions in dopamine signaling have been linked to several neuropsychiatric disorders, including ADHD, schizophrenia, bipolar disorder, autism spectrum disorder, substance use disorder and addiction.
Researchers have developed a first-of-its-kind device to profile the immune function of newborns. Using a single drop of blood, the BiophysicaL Immune Profiling for Infants (BLIPI) system provides real-time insights into newborns’ immune responses, enabling the early detection of severe inflammatory conditions and allowing for timely interventions.
This critical innovation addresses the urgent and unmet need for rapid and minimally invasive diagnostic tools to protect vulnerable newborns, especially those born prematurely.
