Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.

Fire ants form rafts to survive flooding, but how do those bonds work? And what can we learn from them? A professor is researching those questions to expand our knowledge of materials science.

A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.

Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved using the new method of wavefunction matching.

Highly pathogenic H5N1 avian influenza was detected in dairy cattle for the first time in the United States in March, with nine states reporting outbreaks by May. While the method of transmission among cattle is currently unknown, new research demonstrates that a related strain of H5N1, subtype clade 2.3.4.4b, which caused an outbreak in farmed mink in 2022, transmitted through the air to a limited number of ferrets. This is the first time that a member of the group of H5N1 clade 2.3.4.4b viruses has been shown to exhibit this ability. According to the researchers, the findings suggest these viruses are evolving to infect mammals and with potentially increased risk to humans.

Vegetarian and vegan diets are generally associated with better status on various medical factors linked to cardiovascular health and cancer risk, as well as lower risk of cardiovascular diseases, cancer, and death, according to a new review of 49 previously published papers.

Wearable Bluetooth devices can shed light on the care that residents of care homes are receiving and which residents are most in need of social contact, according to a new study.

Spending time in nature is good for us. And knowing more about nature's effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Many studies have focused on how seeing nature affects us. A team of scientists from around the world wants to understand what the nose knows. They are calling for more research into how odors and scents from natural settings impact our health and well-being.

A new study has confirmed a long-held assumption: that orcas take just one breath between dives. The researchers used drone footage and biological data from tags suction-cupped to 11 northern and southern resident killer whales off the coast of B.C. to gather information on the animals' habits. Confirming orcas take only one breath between dives allowed the researchers to calculate how many litres of oxygen adults and juveniles consume per minute. This provides another piece of the puzzle in estimating orca energy expenditure, and eventually, how many fish the animals need to eat per day, key to their conservation.

Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a new study.

A team of researchers has developed a drone that flies autonomously using neuromorphic image processing and control based on the workings of animal brains. Animal brains use less data and energy compared to current deep neural networks running on GPUs (graphic chips). Neuromorphic processors are therefore very suitable for small drones because they don't need heavy and large hardware and batteries. The results are extraordinary: during flight the drone's deep neural network processes data up to 64 times faster and consumes three times less energy than when running on a GPU. Further developments of this technology may enable the leap for drones to become as small, agile, and smart as flying insects or birds.

In a warmer climate, summers warm much faster than winters, according to research into fossil shells. With this knowledge we can better map the consequences of current global warming in the North Sea area.

The optimal design of a novel zeolite catalyst enables tandem reaction that turns greenhouse gases into value-added chemicals, report scientists. By tuning the separation between different active sites on the catalyst, they achieved the stepwise conversion of methane into methanol and then to hydrocarbons at mild conditions. These findings will help reduce energy costs and greenhouse gas emissions across various industrial fields.

Some proteins shift their shape when exposed to different temperatures, revealing previously unknown binding sites for medications. The findings could revolutionize wide swathes of biology by fundamentally changing how protein structure is studied and leveraged for drug design.

'Dust clouds' at the bottom of the deep sea, that will be created by deep-sea mining activities, descend at a short distance for the biggest part. Yet, a small portion of the stirred-up bottom material remains visible in the water at long distances.

In the emperor penguin courtship call, male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 defied this binary. Also unusual was this penguin's male companion, E-81. The pair 'kept company' and sometimes exhibited ritual courtship displays. Researchers studied the courtship calls of E-79 and E-81, recording the birds in their below-freezing enclosure and refining the usual technique for analyzing the bursts.
