Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old galaxy without young, active stars — calling those assumptions into question. ‘Just when you think you understand an astrophysical phenomenon, the universe turns around and surprises us,’ researcher says.

Instead of relying on energy-hungry reactors to generate high temperatures and pressure, researchers are looking underground at Earth’s natural heat and forces to cook up ammonia for fertilizer. In a proof-of-concept study, researchers generated ammonia by mixing nitrogen-laced water with iron-rich rocks — without any energy input or CO2 emission. This new recipe may lead to a more sustainable alternative to current methods, theoretically churning out enough ammonia for 2.42 million years.

Researchers present paper-based temperature and humidity sensors that are accurate, reliable, and eco-friendly. The team created the sensors by printing silver lines on commercially available paper through dry additive nanomanufacturing. As the paper absorbs water vapor, its capacitance change is measured to reflect the relative humidity of the environment, and as the temperature increases, the metallic conductor experiences an increase in resistivity. They successfully detected changes in relative humidity levels from 20% to 90% and temperature variations from 25 C to 50 C.

Boys exposed to violent screen content in the preschool years were more likely to become antisocial and violent themselves a decade later, in their mid-teens, a new study shows.

People with the skin condition psoriasis often have invisible inflammation in the small intestine with an increased propensity for ‘leaky gut’, according to new research. These changes in the gut could explain why psoriasis sufferers often have gastrointestinal problems and are more prone to developing Crohn’s disease.

A new study has described a phenomenon researchers refer to as ‘contagious urinations.’ The study in 20 captive chimpanzees living at the Kumamoto Sanctuary in Japan shows that, when one chimp pees, others are more likely to follow.

Researchers have determined how children’s immune systems react to different kinds of cancer depending on their age. The study reveals significant differences between the immune response of children and adults, and has the potential to lead to new tailored treatments for children with cancer.

Ecologists have identified significant ecological risks associated with the release of hybrid groupers into Hong Kong’s coastal waters, a practice often linked to religious ‘mercy release’ rituals. Their study highlights how the Tiger Grouper-Giant Grouper hybrid (TGGG), also known as the Sabah grouper, disrupts local marine ecosystems by exploiting unique ecological niches and potentially becoming a dominant predator. This research, the first to use advanced DNA metabarcoding to analyze the diet of this hybrid species, underscores the urgent need for public education and conservation measures to mitigate unintended ecological impacts.

In the years following the launch of NASA’s Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way — the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a very clear autumn night as a faint cigar-shaped object roughly the apparent angular diameter of our Moon. A century ago, Edwin Hubble first established that this so-called ‘spiral nebula’ was actually very far outside our own Milky Way galaxy — at a distance of approximately 2.5 million light-years or roughly 25 Milky Way diameters.

Across most of the Northeast, getting bitten by a blacklegged tick– also called a deer tick — is a risk during spring, summer, and fall. A new Dartmouth study, published in Parasites and Vectors, finds that 50% of adult blacklegged ticks carry the bacteria that causes Lyme disease while 20% to 25% of the younger (nymph) blacklegged ticks carry the bacteria.
