Why plant cells need heme: Hidden signal reshapes photosynthesis gene control
For plants, light is an important environmental factor not only as a source of energy for photosynthesis, but also as a signal for capturing environmental information. Light signals are sensed by photoreceptor proteins called phytochromes. The amino acids that make up proteins
X-ray scans uncover Nazi symbols hidden beneath postwar painting
Erich Mercker (1891–1973), a painter from Munich, was quite successful in his day. Between 1933 and 1945, he painted works containing Nazi symbolism, including "Die Stätte des 9. November," which depicts the Feldherrnhalle monument in Munich commemorating the NSDAP's failed
Yeast experiments reveal an evolutionarily conserved backup route for making a molecule that's essential to life
Hiroshima University researchers say a newly proposed three-step "detour" pathway for making dolichol, a molecule cells need to properly process proteins, may be more universal than scientists realized. Experiments in yeast suggest eukaryotes may rely on overlapping biochemical
Why does the Y chromosome retain UTY?
A study, published in the journal Development, is the first to precisely map endogenous UTY occupancy across the human genome and demonstrate that UTY remains functionally involved in transcriptional regulation during early human development.
A 170 km journey by a freshwater stingray challenges long-held conservation assumptions
Most sharks and rays inhabit the oceans, but a small proportion thrive in freshwater. Approximately 4% to 5% of all shark and ray species live in tropical and subtropical rivers around the world. Two main ecological strategies can be distinguished among freshwater sharks and

Gleam-glum effect reveals emotional word cues in children as young as five
The words "tick-tock," "hiss" and "screech" are examples of onomatopoeia because they imitate the sounds they represent: the rhythmic ticking of a clock; an angry cat, or a slowly deflating bike tire; a high-pitched scream. Onomatopoeia is a type of sound symbolism.

AI spots smuggled seahorses, shark fins and sea cucumbers with 92% accuracy
When we think of wildlife trafficking, we might think of rhino horns or baby orangutans sold as pets—but the smuggling of sea creatures, a less well-known crime, is just as damaging to marine ecosystems. Unfortunately, many commonly smuggled marine wildlife items, like shark
'All-in-one' platform developed for multiple trait stacking in crops
A major goal of modern crop breeding is to efficiently combine multiple desirable traits by "stacking" the favorable gene variants (alleles) that contribute to those traits in a single crop variety. However, current strategies are often time-consuming and inefficient.
Could the Milky Way's missing mass be hiding in a swarm of interstellar comets?

A faster way to forecast alien weather
The TRAPPIST-1 system, located about 41 light years from Earth, has been a focal point of much exoplanetary discussion—mainly because it has seven confirmed planets orbiting a dim M-dwarf star. Two of those planets—TRAPPIST-1e and -1f—are thought to be in the star's habitable
