Scientists have found that a specific protein complex significantly influences brain connectivity and cognitive behaviors.
Their studies on mice revealed that disruptions in this complex affect synapse formation and lead to behavioral changes, such as increased anxiety and impaired social interactions, pointing toward new treatment possibilities for mental health conditions.

Research on Heliconius butterflies illustrates how variations in brain circuits are aligned with their unique foraging behaviors, enhancing their spatial and visual memory.
A tropical butterfly species with uniquely expanded brain structures shows a fascinating mosaic pattern of neural expansion linked to a key cognitive innovation.
The study, published today (October 18) in Current Biology, explores the neural basis of behavioral innovation in Heliconius butterflies, the only genus known to feed on both nectar and pollen. As part of this behavior, these butterflies exhibit an impressive ability to learn and remember the locations of their food sources—abilities tied to the expansion of a brain region called the mushroom bodies, which play a crucial role in learning and memory.
At the Facility for Rare Isotope Beams, a major advancement has been achieved with the successful acceleration of a high-power uranium beam, achieving an unprecedented 10.4 kilowatts of continuous beam power.
This achievement not only highlights the difficulty in handling uranium but underscores its importance in generating a diverse range of isotopes for scientific study. The high-power beam led to the discovery of three new isotopes within the first eight hours of its operation, marking a significant breakthrough in nuclear science and expanding our understanding of the nuclear landscape.
Breakthrough in Isotope Research.

Predicting it could drive the carmaker towards a $25 trillion valuation.
Experts believe this ambitious claim is within the realm of possibility. Optimus is still in development but will enter production next year, with Musk stating that Tesla could have “a few thousand” units working in its factories, reaffirming his earlier timeline.
R.I.P. Phil Philip George Zimbardo. March 23, 1933 – October 14, 2024.
“Success is not about reaching a destination; it’s about the journey and the person you become along the way.”
Philip G. Zimbardo, one of the world’s most renowned psychologists, died Oct. 14 in his home in San Francisco. He was 91.
Broadly, Zimbardo’s research explored how environments influence behavior. He is most known for his controversial 1971 study, the Stanford Prison Experiment, with W. Curtis Banks, Craig Haney, and David Jaffe. The study, intended to examine the psychological experiences of imprisonment, revealed the shocking extent to which circumstances can alter individual behavior. To this day, it is used as a case study in psychology classes to highlight both the psychology of evil as well as the ethics of doing psychological research with human subjects.
The new technology uses square steel pipes and plates for a flexible foundation structure.
A Japanese company has designed an earthquake-resistant foundation for fixed-bottom offshore wind turbines. Developed by J-Power and the University of Tokyo, the ‘flexible tripile’ foundation is tailored for Japan’s topography.
The newly devised technology incorporates square steel pipes and steel plates in the foundation’s base plate, creating a flexible structure that can deform relatively easily, according to the company.
J-Power claims that the design provides seismic isolation from the ground, improving constructability in areas with shallow bedrock and reducing vibrations caused by earthquakes.
Plants can emit electric potential when pulling water from their roots to nourish their stems and leaves.
Experiments showed that the electrical potential in plants varies in a cyclic rhythm that matches their daily biological processes. This potential increases with decreased ion concentration or increased pH in the fluid, linking it to the plant’s water transpiration and ion transport mechanisms.
“Our eureka moment was when our first experiments showed it is possible to produce electricity in a cyclic rhythm and the precise linkage between this and the plant’s inherent daily rhythm,” Chakraborty added. “We could exactly pinpoint how this is related to water transpiration and the ions the plant carries via the ascent of sap.”
Chakraborty also noted that not only did the researchers rediscover the plant’s electrical rhythm, articulating it in terms of voltages and currents, alongside potentially tapping electrical power output from them in a sustainable manner with no environmental impact and no disruption to the ecosystem.
Airbus U.S. Space & Defense announced on October 15, 2024, the successful completion of the first demonstration of the Lakota UH-72 drone helicopter for the U.S. Marine Corps, conducted at Marine Corps Air Station New River and Camp Lejeune. This demonstration showcased the capabilities of the Aerial Logistics Connector (ALC) system, designed to enhance logistical support in dispersed and challenging environments. As an autonomous platform, the Lakota UH-72 ensures a continuous supply flow without relying on traditional transportation methods, which are often vulnerable or limited.
It is morally wrong to use AI detectors when they produce false positives that smear students in ways that hurt them and where they can never prove their innocence.
While some educators…
About two-thirds of teachers report regularly using tools for detecting AI-generated content. At that scale, even tiny error rates can add up quickly.
