Phys.org / Euclid discovers the most ancient quasars in the universe
The European Space Agency's Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed ...
Medical Xpress / Pregnancy recruits killer T cells that may guard breasts against cancer for years
An Australian study by researchers at Peter Mac has shown that the natural protection against breast cancer offered by childbearing is due to the influx of killer T cells to the breast. The research shows that the cells begin ...
Phys.org / Researchers use AI to evaluate a systematic framework to describe molecular order in liquid water
Water is the most abundant liquid on Earth's surface, and it is highly anomalous compared with other liquids because it expands upon freezing. The anomalies in water have been linked to how its microscopic structure changes ...
Phys.org / Neutral lipids enable precision control over supramolecular polymerization
The formation of supramolecular polymers within living cells is an emerging strategy for regulating cellular functions, and lipid droplets (LDs) are promising environments for such processes. LDs are cellular organelles composed ...
Medical Xpress / How TV drama shapes social maps in brain, and why conflict stands out
When watching a drama, we quickly learn who is friends with whom—and, just as importantly, who stands against whom. But how does the brain organize this web of alliances, rivalries and conflicts? Researchers from the University ...
Phys.org / Japan space probe skims asteroid in test for planetary defense
A Japanese space probe performed a flyby of a near-Earth asteroid on Sunday in a test mission for technology that could help protect the planet from space rocks.
Phys.org / Rare 309-million-year-old fossils suggest early tetrapods developed without tadpole phase
Scientists have long posited that the earliest water animals to transition to land had amphibious tadpole features, going through a metamorphosis akin to that of today's frogs.
Phys.org / Astronomers may have caught an early galaxy in the process of dying
Astronomers have spotted many "red and dead" galaxies in the early universe. These are massive systems that stopped forming stars surprisingly early in cosmic history. Now, they may have found evidence of one in the act of ...
Phys.org / A young gull's mottled brown plumage acts as a 'not a threat' signal to territorial adults
Birds are known for their distinctive plumage that helps them attract mates during the breeding season. For some birds, the path to adulthood is quite linear. One day they are chicks, and a few months later they are fully ...
Phys.org / Rats show empathy, according to model
A rat first frees a cagemate rat and then shares food with it. Is this animal just as empathetic as humans? In an American study from 2011, researchers observed that rats first freed their fellow rats from a cage and then ...
Tech Xplore / AI-powered social media can subtly manipulate opinion at scale
AI tools used to generate, edit or contextualize social media posts can introduce hidden biases that spread through online networks and shape public opinion, according to new research from the Oxford Internet Institute (OII) ...
Phys.org / Antarctic ozone loss drove unexpected Southern Ocean cooling, climate model shows
The Southern Ocean has long stood out as an oddity in the global climate system. While most of the planet's surface oceans have warmed in response to rising greenhouse gases, waters circling Antarctica showed an unexpected ...
