According to anthropologists and geologists, it's time to acknowledge humans have become the dominant force shaping the moon's environment by declaring a new geological epoch for the moon: the Lunar Anthropocene. They argue the new epoch may have dawned in 1959 when the USSR's unmanned spacecraft Luna 2 alighted on the lunar surface. Read more

ChatGPT may do an impressive job at correctly answering complex questions, but a new study suggests it may be absurdly easy to convince the AI chatbot that it's in the wrong. Read more

Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat. Read more

A study has investigated the possible scenarios that could lead to waning memory in some older people. Read more

There has been a surge in academic and business interest in software as a medical device (SaMD). It enables medical professionals to streamline existing medical practices and make innovative medical processes such as digital therapeutics a reality. Furthermore, SaMD is a billion-dollar market. However, it is not clearly understood as a technological change and emerging industry. Read more

A joint research team in computer science, economics, and geography has developed an artificial intelligence (AI) technology to measure grid-level economic development within six-square-kilometer regions. This AI technology is applicable in regions with limited statistical data (e.g., North Korea), supporting international efforts to propose policies for economic growth and poverty reduction in underdeveloped countries. The research team plans to make this technology freely available for use to contribute to the United Nations' Sustainable Development Goals (SDGs). Read more

Researchers have developed an algorithm to train an analog neural network just as accurately as a digital one, enabling the development of more efficient alternatives to power-hungry deep learning hardware. Read more

Researchers devised a machine-learning-based method to investigate how materials behave at their surfaces. The approach could help with developing new compounds or alloys for use as catalysts, semiconductors, or battery components. Read more

The ability to meet EU climate goals is enhanced by investing in new technologies that remove carbon dioxide from the atmosphere. Although it is currently unprofitable for both companies and countries to do so, there are solutions to make it financially viable. Read more

Fewer women pursue careers in physics than biology, and scientists from around the world believe these differences come down to personal preferences, according to a new study of international scientists. The study's researchers warn that merely chalking this imbalance up to individual choice may diminish the push for gender equality in the sciences. Read more

Women who delivered their previous pregnancy by C-section spent a longer time trying to conceive their next pregnancy. Additionally, women who spent a longer time trying to conceive their current pregnancy were more likely to deliver by C-section. The authors concluded that differences in time spent trying to conceive are unlikely to be due to the surgical procedure itself. Read more

Research reveals that around 20 per cent of all cases of the most severe form of breast cancer may arise from the small group of normal tissue cells carrying an epimutation of a specific gene, called BRCA1.  Read more

To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team has discovered some time ago that a certain iron alloy can be magnetized with ultrashort laser pulses. Read more

On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why researchers are focused on opening a new nanoscale lane on the heat transfer highway by using hybrid quasiparticles called 'polaritons.' Read more

Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent study shows that the interactions between plants and pollinators, which are important for agricultural production, are surprisingly dynamic. For example, the plant and bee species involved in pollination vary greatly between the seasons. Read more

Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's reign. Read more

Comparing PET scans of more than 90 adults with and without mild cognitive impairment (MCI), researchers say relatively lower levels of the so-called 'happiness' chemical, serotonin, in parts of the brain of those with MCI may play a role in memory problems including Alzheimer's disease. Read more

Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well. Read more
