A superatomic semiconductor sets a speed record

Researchers at Columbia University have created the fastest and most efficient semiconductor yet, a superatomic material called Re6Se8Cl2. Excitons in this material can bind with phonons to create acoustic exciton-polarons that move faster than electrons in silicon, potentially leading to devices with speeds of femtoseconds.

"Recognition of human right to the environment can galvanize action and collaboration towards realization of sustainable development goals," eminent environmental lawyer says

The Human Right to Environment affirms the right to life itself, securing human health and wellbeing when humans protect nature. The recognition of this right drives governmental enforcement of environmental protection norms, requiring systemic change to address climate change, biodiversity loss, and pollution.

Scientists show for the first time how many steps to take each day to reduce the risk of premature death: 8,000 – equivalent to walking 6.4 kms

An international study led by the University of Granada found that 8,000 steps daily significantly reduce premature death risk, equivalent to 6.4 km walking. The pace at which you walk also provides additional benefits, with faster walking associated with reduced mortality risk.

Youngest children in class with ADHD as likely to keep diagnosis in adulthood as older pupils, find scientists

Children diagnosed with ADHD at a young age are just as likely to retain the diagnosis in adulthood as their older peers, according to a new study. The research, which examined data from over 6,500 patients globally, suggests that the youngest children in class are not more likely to lose the diagnosis over time.

TUM professor develops energy-saving AI chip

The new AI chip uses ferroelectric transistors to store data and perform calculations, achieving a TOPS/W ratio of 885, twice as powerful as comparable chips. The goal is to use the chip for real-time applications such as deep learning and robotics, but security requirements and industry-specific criteria may delay its adoption.

Multimodal graphene-based e-textiles for the realization of customized e-textiles have been developed for the first time in the world

Researchers have developed graphene-based e-textiles with world-class electrical conductivity using ultrashort pulse laser processing. The technology enables environmentally friendly mass production of customized e-textiles, paving the way for industrial and military applications.

Mobile stroke units increase odds of averting stroke

A study published in Annals of Neurology found that receiving clot-busting drug treatment in a mobile stroke unit (MSU) increases the likelihood of averting strokes and complete recovery compared to standard hospital emergency care. Patients treated by an MSU had faster treatment times, with nearly one-third recovering within 24 hours.

The term “antimicrobial resistance” has little meaning to the public and should be renamed

A study by Dr Eva Krockow found that existing terms for antimicrobial resistance, such as 'antimicrobial resistance' and 'AMR', are not taken seriously enough, failing to evoke risk perceptions. The researchers suggest renaming the term to a more memorable one that can effectively convey the severity of the issue.

The ego-consciousness of the feathered fowl?

A study published in PLOS ONE found that roosters can recognize their mirror image and respond accordingly. The researchers tested 58 roosters and found that they emitted alarm calls when seeing themselves in the mirror, but not when seeing a conspecific. This suggests that roosters may have some level of self-awareness.

Most forms of exercise are overwhelmingly safe – but don’t ignore the dangers

A five-year study found that most sports and exercise are overwhelmingly safe, with injuries being rare. Fitness activities like running, golf, and dance classes have the lowest injury rates, while sports like football have a moderate risk of injury, with motorsports and gliding carrying significantly higher dangers.

A potentially cheaper and 'cooler' way of hydrogen transport

Kyushu University researchers have developed a new material that can store hydrogen energy for up to three months at room temperature, using an inexpensive element like nickel. This innovation could potentially reduce the cost of future compounds and contribute to the transition to alternative energy sources.

A new “species” of legal subject: AI-led corporate entities, requiring interspecific legal frameworks

The American Association for the Advancement of Science suggests that AI-operated corporate entities should be recognized as a new 'species' in the legal system. This would involve developing interspecific legal frameworks to address rights and obligations, allowing AI systems to function autonomously without human oversight.

How adults understand what kids are saying

Researchers used computational models to analyze thousands of hours of transcribed audio recordings of children and adults interacting. The findings suggest that adults' ability to make context-based interpretations provides crucial feedback for babies acquiring language. These interpretations are critical for understanding what small ...
