Fossil named 'Attenborough's strange bird' was the first in its kind without teeth      (via sciencedaily.com)     Original source 

A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.

New research shows migrating animals learn by experience      (via sciencedaily.com)     Original source 

Individual white storks incrementally straightened their migration routes to find more direct ways to move between destinations during the spring migration to summer breeding and nesting grounds, suggesting that experiential learning is an important part of successful migration.

An evolutionary mystery 125 million years in the making      (via sciencedaily.com)     Original source 

Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.

The crow's best friend: Humans      (via sciencedaily.com)     Original source 

A new study has found that when humans are suddenly absent from the urban environment, the activity of the crows and ringneck parakeets that 'live' in the area reduces significantly. Conversely, the graceful prinias, who are generally considered shy, increased their activity.

A model for the evolution of intelligence      (via sciencedaily.com)     Original source 

When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid off a container of food, are the only predictors of brain size and innovative behavior in the wild.

Evolution-capable AI promotes green hydrogen production using more abundant chemical elements      (via sciencedaily.com)     Original source 

A research team has developed an AI technique capable of expediting the identification of materials with desirable characteristics. Using this technique, the team was able to discover high-performance water electrolyzer electrode materials free of platinum-group elements -- substances previously thought to be indispensable in water electrolysis. These materials may be used to reduce the cost of large-scale production of green hydrogen -- a next-generation energy source.

Researchers create coating solution for safer food storage      (via sciencedaily.com)     Original source 

Galvanized steel containers and surfaces are used for harvested produce because of their durability, strength and lower cost compared to stainless steel. However, bacteria residing in storage containers can cause corrosion. The new coating will reduce corrosion by at least 70 percent, researchers say.

Study results show 25% of pregnant people are not getting enough omega-3 fatty acids from their diet or dietary supplements      (via sciencedaily.com)     Original source 

Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.

Convergent evolution of algal CO2-fixing organelles      (via sciencedaily.com)     Original source 

Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independent evolution of pyrenoids in different algal groups.

Mercury rising: Study sheds new light on ancient volcanoes' environmental impact      (via sciencedaily.com)     Original source 

Massive volcanic events in Earth's history that released large amounts of carbon into the atmosphere frequently correlate with periods of severe environmental change and mass extinctions. A new method to estimate how much and how rapidly carbon was released by the volcanoes could improve our understanding of the climate response, according to an international team.

Microbial viruses act as secret drivers of climate change      (via sciencedaily.com)     Original source 

Scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment.

Lake ecosystems: Nitrogen has been underestimated      (via sciencedaily.com)     Original source 

An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. The result: increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish kills. Until now, controls in lake management have focused primarily on phosphorus inputs to counteract this effect. Now, this dogma is shaken by a study showing that nitrogen is also a critical driver for phytoplankton growth in lakes worldwide.

Researchers improve the stability of perovskite solar cells      (via sciencedaily.com)     Original source 

Perovskite solar cells are considered the strongest contender to replace silicon solar cells. While they achieve high power conversion energy, they also suffer from lead leakage and perovskite degradation due to moisture. Now scientists leverage the technique of interfacial passivation, where lead ions are bound by crown ether B18C6, obtaining 21.7% power conversion energy. The crown ether also resists degradation due to moisture for 300 hours at room temperature and 85% humidity.

A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.

Small dietary changes can cut your carbon footprint by 25%      (via sciencedaily.com)     Original source 

New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.
