New research, led by the University of Bristol, suggests that feathers arose 100 million years before birds - changing how we look at dinosaurs, birds, and pterosaurs, the flying reptiles.
New Guinea is one of the only places in the world where frogs are safe from the species-destroying chytrid fungus. An international team of scientists has published a new paper that shows how to keep it that way, but they need help to carry out their plan.
Biophysicists from the Moscow Institute of Physics and Technology have joined forces with colleagues from France and Germany to create a new fluorescent protein. Besides glowing when irradiated with ultraviolet and blue light, it is exceedingly small and stable under high temperatures.
How did some marine fish manage to make their way from the salty sea to the newly available freshwater niches after the last ice age and eventually differentiate from their marine brethren?
St. Paul, MN (May, 2019)--The chemical compound chloropicrin was first synthesized in 1848 by Scottish chemist John Stenhouse and first applied to agriculture in 1920 when it was used to cure tomato "soil sickness." Over the next decade, it was used to restore pineapple productivity in Hawaii and to address soil fungal problems in California. Over time, it began to be widely used as a fungicide, herbicide, insecticide, and nematicide.
Although pollen has covered cars for weeks and allergy sufferers have been sneezing, we think of sex as being the realm of animals. But plant sex can be quite interesting, especially in species that can have male or female flowers.
A group of scientists from Russia and Ireland found out how the quality of tissue-engineered biomeshes (biological "frame" which is used for tissue repair) is affected by various chemical fixatives (cross-linkers). Such compounds form chemical "bridges" between bio mesh polymers and change its mechanical and functional properties. It will help to select cross-linkers for the treatment of certain transplants. The research results are published in the official journal of the International Xenotransplantation Association.
BINGHAMTON, N.Y. - Light at night might be convenient for humans, but it's having a detrimental effect on amphibian populations, according to new research from Binghamton University, State University of New York.
From our perches in the urban jungle - or even in the leafier parts of suburbia - we often have a tough time naming the last plant we saw. Even if we just ate part of it. This is a symptom of "plant blindness," a term coined two decades ago by researchers who showed that modern civilization is perilously disconnected from the plant kingdom. Our blindness has progressed even further since then, to the point where we hardly recognize the plants that feed us every day.
As food enters the intestine, it embarks on a windy, lengthy journey. For most of the route, its surroundings don't appear to change much. But new research from Rockefeller's Daniel Mucida shows that the food-processing canal consists of compartments that pace the immune system's reactions to the food passing through--with less aggressive defenses in the first segments where nutrients are absorbed, and more forceful responses at the end, where pathogens are eliminated.
Crabs from a single species rely on different camouflage techniques depending on what habitat they live in, new research shows.
Symbiotic algae living inside corals provide those animals with their vibrant color, as well as many of the nutrients they need to survive. That algae, and other microbes within the bodies of corals, have been extensively studied--yet until now, researchers have largely ignored the microbial communities just outside of the coral colonies.
Imagine a technology that could target pesticides to treat specific spots deep within the soil, making them more effective at controlling infestations while limiting their toxicity to the environment.
Anthropologists discovered a tool made out of high-quality translucent jadeite with an intact rosewood handle at a site where the ancient Maya processed salt in Belize. The discovery of these high-quality materials--jadeite and rosewood--used as utilitarian tools, demonstrates that salt workers played an important role in the Classic Maya marketplace economy more than 1,000 years ago.
