3D-printed vegan seafood could someday be what's for dinner      (via sciencedaily.com)     Original source 

More mock seafood options are needed because of unsustainable fishing and aquaculture practices, which can harm the environment. Now, researchers have a new approach for creating desirable vegan seafood mimics that taste good, while maintaining the healthful profile of real fish. They 3D-printed an ink made from microalgae protein and mung bean protein, and their proof-of-concept calamari rings were air-fried into a snack.

Chemicals from maize roots influence wheat yield      (via sciencedaily.com)     Original source 

Maize roots secrete certain chemicals that affect the quality of soil. In some fields, this effect increases yields of wheat planted subsequent to maize in the same soil by more than 4%. While the findings from several field experiments show that these effects are highly variable, in the long term they may yet help to make the cultivation of grains more sustainable, without the need for additional fertilizers or pesticides.

The positional transmitter of statoliths unveiled: It keeps plants from getting lazy      (via sciencedaily.com)     Original source 

Plants orient their organs in response to the gravity vector, with roots growing towards gravity and shoots growing in the opposite direction. The movement of statoliths responding to the inclination relative to the gravity vector is employed for gravity sensing in both plants and animals. However, in plants, the statolith takes the form of a high-density organelle, known as an amyloplast, which settles toward gravity within the gravity sensing cell. Despite the significance of this gravity sensing mechanism, the exact process behind it has eluded scientists for over a century.

Researchers identify peptides for pollen tube growth in rice      (via sciencedaily.com)     Original source 

Rapid alkalinization factors (RALFs) are required for pollen tube germination and elongation, an essential process in plant fertilization. But their role in monocot plants remains unexplored. Scientists have now identified OsRALF17 and OsRALF19 in rice and determined their functions in pollen tube germination and growth. This study provides novel insights into the role of RALFs in rice fertilization, paving the way for enhanced grain yield.

Webb reveals colors of Earendel, most distant star ever detected      (via sciencedaily.com) 

NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang. Webb's NIRCam (Near-Infrared Camera) instrument reveals the star to be a massive B-type star more than twice as hot as our Sun, and about a million times more luminous.

The oldest and fastest evolving moss in the world might not survive climate change      (via sciencedaily.com)     Original source 

A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

Potential novel breakthrough treatment for fungal infections      (via sciencedaily.com)     Original source 

Fungal infections are killing thousands of Americans each year, some with a morbidity rate of nearly 80%. To make matters worse, only a handful of antifungal treatments are available, and even those are becoming less effective as fungi become more resistant. However, researchers recently published findings indicating that a novel breakthrough treatment may have been discovered.

Scientists discover the highest-energy light coming from the sun      (via sciencedaily.com) 

New research details the discovery of the highest-energy light ever observed from the sun. The international team behind the discovery also found that this type of light, known as gamma rays, is surprisingly bright. That is, there's more of it than scientists had previously anticipated.

Gravitational arcs in 'El Gordo' galaxy cluster      (via sciencedaily.com) 

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.

New clues on the source of the universe's magnetic fields      (via sciencedaily.com) 

Researchers offer insight into the source of cosmic magnetic fields. The research team used models to show that magnetic fields may spontaneously arise in turbulent plasma. Their simulations showed that, in addition to generating new magnetic fields, the turbulence of those plasmas can also amplify magnetic fields once they've been generated, which helps explain how magnetic fields that originate on small scales can sometimes eventually reach to stretch across vast distances.

Astronomers shed new light on formation of mysterious fast radio bursts      (via sciencedaily.com) 

International team reports on a radio pulsar phase of a Galactic magnetar that emitted a fast radio burst in 2020; observations suggest unique origins for 'bursts' and 'pulses,' which adds to FRB formation theory.

Hubble sees evaporating planet getting the hiccups      (via sciencedaily.com) 

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.

Webb snaps highly detailed infrared image of actively forming stars      (via sciencedaily.com)     Original source 

Young stars are rambunctious! NASA's James Webb Space Telescope has captured the 'antics' of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.

Astronomers reveal new features of galactic black holes      (via sciencedaily.com) 

An international team of scientists, including astrophysicists, report on a dedicated observational campaign on the Galactic microquasar dubbed GRS 1915+105. The team revealed features of a microquasar system that have never before been seen. Using the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers discovered a quasi-periodic oscillation (QPO) signal in the radio band for the first time from any microquasar systems.

Galaxy J1135 reveals its water map      (via sciencedaily.com) 

Researchers look at water in galaxies, its distribution and in particular its changes of state from ice to vapor, as important markers indicating areas of increased energy, in which black holes and stars are formed. A new study has now revealed the distribution of water within the J1135 galaxy, which is 12 billion light years away and formed when the Universe was a 'teenager', 1.8 billion years after the Big Bang . This water map, with unprecedented resolution, is the first ever to be obtained for such a remote galaxy. The map can help scientists to understand the physical processes taking place within J1135 and shed light on the dynamics, still partially unclear, surrounding the formation of stars, black holes and galaxies themselves.
