Destroyed habitats, poaching, and prey depletion have dramatically reduced tiger habitats around the world. Today, tigers occupy just 5–10% of their historical habitats. But on the Indonesian island of Sumatra, an important population of critically endangered Sumatran tigers
A remarkable resistance to venom has been discovered in a frog that feasts on hornets despite their deadly stingers. This frog could potentially serve as a model organism for studies on mechanisms underlying venom tolerance.
The European Parliament recently backed changes to the rules around the labeling and marketing of plant-based meat alternatives. New definitions specify that words like "burger," "sausage," or "steak," refer exclusively to animal protein. To get to the meat of the matter, this
Starting school is a time of great anticipation and excitement for young children and families. The buildup can last for months as children go to orientation days, and families prepare with new uniforms, bags and lunch boxes. Significant adults in the child's life are eager to

As small aquatic habitats disappear at an alarming rate, private garden ponds may help compensate for the loss of natural habitats and support biodiversity in urban areas. However, as these ponds become increasingly popular, the spread of invasive species is emerging as a
Thulium fiber lasers, operating at a wavelength of 2 micrometers, are valued for applications in medicine, materials processing, and defense. Their longer wavelength makes stray light less damaging compared to the more common ytterbium lasers at 1 micrometer.
The origin of the elusive preference of copper chalcogenides for selectively converting carbon dioxide (CO2) into formate has long puzzled researchers. Researchers at National Taiwan University have identified a charge-redistribution mechanism that resolves this long-standing
Young people with fewer financial resources, especially boys, are the most exposed to advertising about how to make easy money. So confirms a pioneering study by Pompeu Fabra University (UPF), which has for the first time analyzed how the socioeconomic level and gender of young
Long non-coding RNAs (lncRNAs) are RNA transcripts longer than 200 nucleotides that do not code for proteins. Once considered mere transcriptional noise, lncRNAs are now known to play vital roles in plant growth, development, and responses to environmental stress. However, few
As nearly one in six couples experience fertility issues, in-vitro fertilization (IVF) is an increasingly common form of reproductive technology. However, there are still many unanswered scientific questions about the basic biology of embryos, including the factors determining
A recent advance in the science of hydrogen fuel production could enable higher output and more sustainable production of this renewable energy source, researchers with Stockholm's KTH Royal Institute of Technology report.
All-solid-state batteries (ASSBs) using silicon (Si) anodes are among the most promising candidates for high-energy and long-lasting power sources, particularly for electric vehicles. Si can store more lithium than conventional graphite, but its volume expands by roughly 410%
How wildfires spread is more variable and unpredictable than Canada's standard models assume, new research from UBC Okanagan data scientists shows.

Dolphins produce a range of vocalizations used for echolocation and communication. These vocalizations vary with social context, environmental conditions, external stimuli, and communication, reflecting their cognitive and behavioral complexity.
A fossil site in Bolivia preserves thousands of traces of dinosaurs who walked, ran, and swam along an ancient coastline, according to a study by Raúl Esperante of the Geoscience Research Institute, California, U.S., and colleagues.
Male infertility is a major issue worldwide and its causes remain unclear. Now, an international team of researchers led by Hiroki Shibuya at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan has discovered a key structure in the germ cells of male mice, that
Bumble bees respond to physical disturbance of their nest with a sequence of defensive behaviors that lasts up to 10 minutes, according to a study by Sajedeh Sarlak at the University of Konstanz, Germany, and colleagues.
Scientists have developed a revolutionary technique for creating colors that can change on command. These are structural colors that don't rely on dyes or pigments and can be used for display signage, adaptive camouflage and smart safety labels, among other applications.

Researchers at National Taiwan University have uncovered, for the first time at atomic resolution, how the human proteasome recognizes branched ubiquitin chains. Their finding reveals a multivalent decoding mechanism that enhances protein degradation accuracy and speed.
There's been a lot of speculation recently about interstellar visitor 3I/ATLAS—much of which is probably caused by low-quality data given that we have to observe it from either Earth, or in some cases, Mars. In either case, it's much further away than what would be the ideal.
In 2024, along with 20,000 others, I attended a sold-out metal show in Manchester. Unlike most concerts at the Co-op Live Arena, however, none of us in the packed-out venue knew who we were actually seeing. The band was Sleep Token—a masked and anonymous collective formed in
