Animals keep eating precious plants—we used "smell misinformation" to keep them away
In places where we need to protect valuable plants—whether for ecological or economic reasons—local herbivores can cause significant damage......»»
3D leaf edge reconstruction method enhances plant morphology analysis
Leaves, essential for photosynthesis and other physiological functions, exhibit diverse shapes that help plants adapt to their environments. Traditional methods for measuring leaf morphology have relied heavily on 2D imaging, which fails to capture t.....»»
Saturday Citations: Color vision created demand for colorful animals; observing black hole light echoes; deadlines!
This week, researchers hypothesized that human culture is distinguished from cultures of other species like whales by unique open-endedness—the ability to communicate and understand an infinite number of possibilities. An ancient unicellular organi.....»»
Encouraging quiet during zoo visits might lead to a better appreciation of the animals, say researchers
Encouraging quietness during zoo trips can help visitors better appreciate their inhabitants and lead to more fulfilling, respectful and informative experiences, a new paper argues......»»
The rise of color vision in animals: Study maps dramatic 100-million-year explosion in color signals
Colors are widely used in communication within and among animal species. For example, peacocks proudly display their vibrant tails, adorned with iridescent eyespots, to attract peahens for courtship. This is a classic example of sexual selection usin.....»»
Scientists reveal strigolactone perception mechanism and role in tillering responses to nitrogen
"How is plant growth controlled?" and "What is the basis of variation in stress tolerance in plants?" were among the 125 most challenging scientific questions, according to the journal Science in 2016......»»
Researchers discover genetic reason for the red, yellow and orange bills of Australian finches
What gives an Australian finch its brilliantly colored red, yellow or orange bill? A major new study has uncovered the genetic switches controlling these distinctive colors, revealing a key piece in the puzzle of how animals develop their coloration......»»
Evolutionary anthropologist presents hypothesis about why humans are dominating the world over other animals
Why is human culture—the shared body of knowledge passed down across generations—so much more powerful than animal cultures?.....»»
Australian dragon study reveals surprising link between motor systems control and sleep rhythms
Sleep is one of the most mysterious, yet ubiquitous components of our biology. It has been described in all major groups of animals, including worms, jellyfish, insects or cephalopods, and in all vertebrates, from fish to humans. Common characteristi.....»»
Ancient unicellular organism indicates embryonic development might have existed prior to animals" evolution
Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals......»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
"Shallow" sports and "deep" social hierarchies: Not all pecking orders are created equally
University of Michigan researchers have added a new dimension to the mathematics used to predict the outcomes of all manner of competitions, including sports, games and social hierarchies in both humans and animals......»»
Bioinspired hydrogels harness sunlight: A step closer to artificial photosynthesis
Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature's method, using sunlight to drive chemical react.....»»
New research reveals how stormy conditions affect albatrosses" ability to feed
Albatrosses are exceptionally mobile and use the wind to travel hundreds of thousands of miles to feed on squid, fish, or other animals found near the water surface in the open ocean. In fact, some larger species of albatrosses are so reliant on the.....»»
New research may lead to potatoes that are less reliant on nitrogen fertilizers
Because nitrogen fertilizers contribute to global greenhouse gas emissions, scientists are looking for ways to modify agricultural plants so that they rely on less nitrogen. In research published in New Phytologist, investigators have found that bloc.....»»
Spraying rice with zinc oxide nanoparticles protects yields during heat waves, study finds
A small team of horticulturists in China and the U.S. has found that spraying rice plants with a zinc oxide nanoparticle solution helps them better handle the stress of a heat wave. In their study, published in Proceedings of the National Academy of.....»»
Misinformation really does spread like a virus, according to mathematical models drawn from epidemiology
We're increasingly aware of how misinformation can influence elections. About 73% of Americans report seeing misleading election news, and about half struggle to discern what is true or false......»»
Svalbard Global Seed Vault evokes epic imagery and controversy because of the symbolic value of seeds
Two-thirds of the world's food comes today from just nine plants: sugar cane, maize (corn), rice, wheat, potatoes, soybeans, oil-palm fruit, sugar beet and cassava. In the past, farmers grew tens of thousands of crop varieties around the world. This.....»»
Study reveals effect of slope position on nonstructural carbohydrates in biological soil crusts
Nonstructural carbohydrates (NSCs) provide energy for metabolic processes in plants and play a key role in plant growth, defense and osmoregulation. However, the regulation of NSC in biological soil crusts across different slope positions remains unc.....»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
