Autism should not be seen as single condition with one cause, say scientists

Autism should not be viewed as a single condition with a unified underlying cause, according to scientists who found that those diagnosed early in childhood typically have a distinct genetic profile to those diagnosed later.

The international study, based on genetic data from more than 45,000 autistic people in Europe and the US, showed that those diagnosed in early childhood, typically before six years old, were more likely to show behavioural difficulties from early childhood, including problems with social interaction, but remain stable.

Those diagnosed with autism later, typically after the age of 10, were more likely to experience increasing social and behavioural difficulties during adolescence and also had an increased likelihood of mental health conditions such as depression.

Study reveals genetic and developmental differences in people with earlier versus later autism diagnosis

Researchers find different genetic profiles related to two trajectories that autistic children tend to follow. One is linked to early diagnosis and communication difficulties in infancy. The other is linked to later diagnosis, increased social and behavioral difficulties in adolescence, and higher rates of conditions like ADHD, depression, and PTSD.

An international study led by researchers at the University of Cambridge has discovered that diagnosed in early childhood has a different genetic and developmental profile than that of autism diagnosed from late childhood onwards.

The scientists say that the findings challenge the long-held assumption that autism is a single condition with a unified underlying cause.

New Sodium Battery Design Works Even at Subzero Temperatures

A new technique stabilizes a metastable form of sodium solid electrolyte, enabling all-solid-state sodium batteries to maintain performance even at subzero temperatures. All-solid-state batteries are considered a safe and powerful option for running electric vehicles, electronics, and even storin

All Analysis and Records Withheld on DoD’s Own Released UAP Footage

The Department of Defense (DoD) has denied a Freedom of Information Act (FOIA) request seeking records connected to the review, redaction, and release of a UAP video published by the All-domain Anomaly Resolution Office (AARO) earlier this year.

The request, filed May 19, 2025, sought internal communications, review logs, classification guidance, legal opinions, and technical documentation tied to the public posting of the video titled “Middle East 2024.” The video, showing more than six minutes of infrared footage from a U.S. military platform, was released in May 2025 and remains unresolved by AARO.

Photodiode design using germanium solves key challenge in on-chip light monitoring

Programmable photonics devices, which use light to perform complex computations, are emerging as a key area in integrated photonics research. Unlike conventional electronics that transmit signals with electrons, these systems use photons, offering faster processing speeds, higher bandwidths, and greater energy efficiency. These advantages make programmable photonics well-suited for demanding tasks like real-time deep learning and data-intensive computing.

A major challenge, however, lies in the use of power monitors. These sensors must constantly track the optical signal’s strength and provide the necessary feedback for tuning the chip’s components as required. However, existing on-chip photodetectors designed for this purpose face a fundamental tradeoff. They either have to absorb a significant amount of the optical signal to achieve a strong reading, which degrades the signal’s quality, or they lack the sensitivity to operate at the low power levels required without needing additional amplifiers.

As reported in Advanced Photonics, Yue Niu and Andrew W. Poon from The Hong Kong University of Science and Technology have addressed this challenge by developing a germanium-implanted silicon waveguide photodiode. Their approach overcomes the tradeoffs that have hindered existing on-chip power monitoring technologies.

Scientists finally prove that a quantum computer can unconditionally outperform classical computers

A quantum computer has demonstrated that it can solve a problem more efficiently than a conventional computer. This achievement comes from being able to unlock a vast memory resource that classical computing cannot match.

How the Red Sea went completely dry before being flooded by the Indian Ocean over 6 million years ago

Scientists at King Abdullah University of Science and Technology (KAUST) have provided conclusive evidence that the Red Sea completely dried out about 6.2 million years ago, before being suddenly refilled by a catastrophic flood from the Indian Ocean. The findings put a definitive time on a dramatic event that changed the Red Sea.

Using , microfossil evidence, and geochemical dating techniques, the KAUST researchers showed that a massive change happened in about 100,000 years—a blink of an eye for a major geological event. The Red Sea went from connecting with the Mediterranean Sea to an empty, salt-filled basin. Then, a massive flood burst through volcanic barriers to open the Bab el-Mandab strait and reconnect the Red Sea with the world’s oceans.

The work is published in the journal Communications Earth & Environment.
