Novel genetic plant regeneration approach without the application of phytohormones      (via sciencedaily.com)     Original source 

Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.

Missing link in species conservation: Pharmacists, chemists could turn tide on plant, animal extinction      (via sciencedaily.com)     Original source 

As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.

Discovery of mechanism plants use to change seed oil could impact industrial, food oils      (via sciencedaily.com)     Original source 

Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.

Trotting robots reveal emergence of animal gait transitions      (via sciencedaily.com)     Original source 

A four-legged robot trained with machine learning has learned to avoid falls by spontaneously switching between walking, trotting, and pronking -- a milestone for roboticists as well as biologists interested in animal locomotion.

Fading lights: Multiple threats to North America's firefly populations      (via sciencedaily.com)     Original source 

Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.

Long snouts protect foxes when diving headfirst in snow      (via sciencedaily.com)     Original source 

When hunting for mice in winter, red and arctic fox are known to plunge headfirst at speeds of 2-4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new study.

Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables      (via sciencedaily.com)     Original source 

Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables. A gastrophysicist puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.

Study details a common bacterial defense against viral infection      (via sciencedaily.com)     Original source 

Researchers report on the molecular assembly of one of the most common anti-phage systems -- from the family of proteins called Gabija -- that is estimated to be used by at least 8.5%, and up to 18%, of all bacteria species on Earth.

Test reveals mice think like babies      (via sciencedaily.com)     Original source 

Are mice clever enough to be strategic? A neuroscientist who studies learning in humans and animals, and who has long worked with mice, wondered why rodents often performed poorly in tests when they knew how to perform well. With a simple experiment, and by acting as 'a little bit of a mouse psychologist,' he and his team figured it out.

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.

Food in sight? The liver is ready!      (via sciencedaily.com)     Original source 

What happens in the body when we are hungry and see and smell food? A team of researchers has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of nerve cells in the brain, the mitochondria of the liver cells change and prepare the liver for the adaptation of the sugar metabolism. The findings could open up new avenues for the treatment of type 2 diabetes.

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.
