Surprising evolutionary pattern in yeast study      (via sciencedaily.com)     Original source 

Research study reports intriguing findings made through innovative artificial intelligence analysis about yeasts -- small fungi that are key contributors to biotechnology, food production, and human health. These findings on simple yeast organisms not only challenge widely accepted ideas about yeast evolution, but also provides access to an incredibly rich yeast analysis dataset that could have major implications for future evolutionary biology and bioinformatics research for years to come.

Could fishponds help with Hawaii's food sustainability?      (via sciencedaily.com)     Original source 

Indigenous aquaculture systems in Hawaii, known as loko i'a or fishponds, can increase the amount of fish and fisheries harvested both inside and outside of the pond. Today, aquaculture supplies less than 1% of Hawaii's 70 million pounds of locally available seafood, but revitalization of loko i'a has the potential to significantly increase locally available seafood.

AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes      (via sciencedaily.com)     Original source 

Elucidating the relationship between the sequences of non-coding regulatory elements and their target genes is key to understanding gene regulation and its variation between plant species and ecotypes. Now, an international research team developed deep learning models that link gene sequence data with mRNA copy number for several plant species and predicted the regulatory effect of gene sequence variation.

These jacks-of-all-trades are masters, too: Yeast study helps answer age-old biology question      (via sciencedaily.com)     Original source 

The results suggest that internal -- not external -- factors are the primary drivers of variation in the types of carbon yeasts can eat, and the researchers found no evidence that metabolic versatility, or the ability to eat different foods, comes with any trade-offs. In other words, some yeasts are jacks-of-all-trades and masters of each.

Scientists replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater      (via sciencedaily.com)     Original source 

Scientists have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a 'single cell protein' cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices.

How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon      (via sciencedaily.com)     Original source 

How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.

Unveiling the lionfish invasion in the Mediterranean Sea      (via sciencedaily.com)     Original source 

Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.

Color variants in cuckoos: The advantages of rareness      (via sciencedaily.com)     Original source 

Every cuckoo is an adopted child -- raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morph that looks like a sparrowhawk, and a rufous morph. Male cuckoos are always gray.

How parasites shape complex food webs      (via sciencedaily.com)     Original source 

A new study sheds light on how parasites, often overlooked, can dramatically affect the balance between predator and prey populations. Researchers developed a groundbreaking mathematical framework that predicts when predators, prey, and parasites can coexist, considering factors like random fluctuations and parasite effects on both populations. This research provides a valuable tool for conservation by helping predict how parasites influence ecosystem resilience and informing strategies to protect vulnerable species.

Bioluminescence first evolved in animals at least 540 million years ago      (via sciencedaily.com)     Original source 

Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.

Squids' birthday influences mating      (via sciencedaily.com)     Original source 

The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become 'consorts' which fight for mating opportunities. Those which hatch later become 'sneakers,' which use more clandestine mating tactics. Researchers found that the mating tactic determined by the birth date was fixed for the squid's whole life. Understanding how mating tactics are influenced by birth date, and the environmental conditions at that time, can help researchers consider how squid might be affected by climate change and the implications for marine resource management.

New compound from blessed thistle promotes functional nerve regeneration      (via sciencedaily.com)     Original source 

Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have shown that Cnicin significantly accelerates axon (nerve fibers) growth.
