Biofortified rice to combat deficiencies      (via sciencedaily.com)     Original source 

Vitamin B1 is an essential micronutrient for human beings. Its deficiency is the cause of numerous diseases of the nervous and cardiovascular systems. Researchers have achieved a significant advance in the fight against vitamin B1 deficiency, frequently associated with a rice-based diet. By specifically targeting the nourishing tissues of the rice grain, the scientists have succeeded in considerably increasing its vitamin B1 content, without compromising agronomic yield. These results could help solve a major public health problem in regions where rice is the staple food.

The hidden role of the Milky Way in ancient Egyptian mythology      (via sciencedaily.com)     Original source 

Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.

CHEOPS detects a 'rainbow' on an exoplanet      (via sciencedaily.com)     Original source 

The CHEOPS space telescope is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which occurs if the light from the star -- the 'sun' around which the exoplanet orbits -- is reflected by clouds made up of a perfectly uniform substance. If this hypothesis is confirmed, this would be the first detection of this phenomenon outside our solar system.

Stellar collisions produce strange, zombie-like survivors      (via sciencedaily.com)     Original source 

Densely packed, fast-moving stars at the Milky Way's center can collide with each other. New research uses simulations to explore the outcomes of these collisions. Some collisions are more like 'violent high fives' while others are full-on mergers.

NASA's Webb probes an extreme starburst galaxy      (via sciencedaily.com)     Original source 

A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.

New sunflower family tree reveals multiple origins of flower symmetry      (via sciencedaily.com)     Original source 

A new sunflower family tree used skimmed genomes to increase the number of species sampled, revealing that flower symmetry evolved multiple times independently, a process called convergent evolution, among the members of this large plant family.

Researchers discover key gene for toxic alkaloid in barley      (via sciencedaily.com)     Original source 

Barley is one of the most important cereal crops on a global scale. Many barley cultivars produce a toxic alkaloid called gramine that affects the suitability of barley as fodder, but also helps to protect barley from pathogens. So far, the potential of manipulating gramine levels has not been harnessed for plant breeding, because the genetic basis of gramine production has been unresolved. Research groups now disclose the complete biosynthetic pathway of gramine and demonstrate how gramine biosynthesis can be introduced into model organisms or removed from barley.

Lyrebird synchronizes elements of its mating dance      (via sciencedaily.com)     Original source 

To woo a mate, the Albert's Lyrebird of Australia becomes a real song-and-dance bird. Each male first chooses a stage of entangled vines, then in performance he shakes the vines as part of his courtship footwork, synchronizing each shake with the beat of his striking song.

ALMA finds new molecular signposts in starburst galaxy      (via sciencedaily.com)     Original source 

The ALMA radio telescope has detected more than 100 molecular species, including many indicative of different star formation and evolution processes, in a galaxy where stars are forming much more actively than in the Milky Way. This is far more molecules than were found in previous studies. Now the team will try to apply this knowledge to other galaxies.

Combination of the climate crisis and continued deforestation may result in significant damage to the animal world      (via sciencedaily.com)     Original source 

A new study states that the combination of global warming and extreme heat events, alongside the continued expansion of deforestation in the world, may be devastating for many species of animals, especially those that know how to climb trees. As part of the study, the researchers focused on lizards and showed that following the effects of climate change, they will seek refuge from the hot ground by spending a lot of time on trees. However, due to human-related activities, such as deforestation, urbanization and the expansion of agricultural lands at the expense of natural lands, the availability of trees in the areas where the lizards live will decrease, and this may lead to the collapse of many populations.
