Alien plants and animals threaten Antarctica
While scientists globally have been tracking the impact of introduced, non-indigenous species into environments—this collaborative research between La Trobe University, the Arthur Rylah Institute and Monash University is the first to document alien.....»»
Photosynthesis is under threat in an increasingly warm world, says researcher
The basis of all life on Earth is photosynthesis. So, what happens if it is disrupted? Today, advanced measurement tools can reveal how climate change is affecting plants' ability to process the energy from sunlight......»»
Study combines woodchips and biochar to clean water of pharmaceuticals, nutrients
What happens to ibuprofen after it eases your throbbing headache? Like many pharmaceuticals, it can remain in an active form when our bodies flush it out. That's a problem, because although wastewater treatment plants are good at reducing nutrient po.....»»
Wild animals can also experience trauma and adversity: Ecologists create an index to track the effects
Psychologists know that childhood trauma, or the experience of harmful or adverse events, can have lasting repercussions on the health and well-being of people well into adulthood. But while the consequences of early adversity have been well research.....»»
How plants compete for light: Researchers discover new mechanism in shade avoidance
Plants that are close together do everything they can to intercept light. This "shade avoidance" response has been extensively researched. It is therefore even more remarkable that researchers from the laboratory of Molecular Biology at Wageningen Un.....»»
Nitrogen-fixing plant diversity declines with over-fertilization, study finds
Anthropogenic nitrogen deposition and climate change can reduce the competitive advantage of nitrogen-fixing plants, leading to reduced diversity of these plants in a community. Surprisingly, changes in temperature and aridity do not contribute to th.....»»
Owners" belief in horse emotion is linked to healthier animals, new study shows
Researchers have shown that owners who believe in their horses' emotions and treat them with care, have animals that are significantly healthier and better looked after. In many low and middle-income countries (LMICs), working horses are essential to.....»»
Loss of "nitrogen fixers" threatens biodiversity, ecosystems, say biologists
Mississippi State University is part of a European-American collaboration studying how human activities, like fertilizer use and pollution, are impacting nitrogen-fixing plants which are crucial for maintaining healthy ecosystems by adding nitrogen t.....»»
EU delays on dangerous chemicals threaten health, environment: watchdog
The European Commission's long delays in deciding whether some dangerous chemicals can be used pose a threat to human health and the environment, the EU's rights watchdog said on Monday......»»
Materials of the future can be extracted from wastewater
A group of researchers is on the way to revolutionizing what biomass from wastewater treatment plants can be used for. Biopolymers from bacteria can be a sustainable alternative to oil-based products, and phosphorus and other minerals can also be har.....»»
Q&A: A faster way to identify drought-resistant plants for crop breeding research
Climate change is making droughts more common and more severe—which makes research into developing drought-resistant crops more important than ever. Now researchers have developed a new framework that should expedite this important research......»»
Nonnative plants are a major force behind global insect invasions, study finds
In an article in the journal BioScience, an international team of researchers led by Dr. Cleo Bertelsmeier from the University of Lausanne, Switzerland, argues that the global spread of nonnative plants is a key factor driving the growing number of i.....»»
Discovery of key protein for biosynthesis of plant defense steroids could enhance pest control strategies
Researchers at the Max Planck Institute for Chemical Ecology have identified GAME15 as a key protein that regulates the biosynthesis of both steroidal glycoalkaloids and steroidal saponins in plants of the genus Solanum......»»
Stem carbohydrate richness in two cycad species
Terrestrial plants have developed strategies to cope with suboptimal conditions. Storage of nonstructural resources is one of those strategies. Nonstructural carbohydrates (NSCs) of plants are primarily sugars and starch, and have been studied extens.....»»
Microbiome studies in humans and zoo animals pave the way for new drug development
Microorganisms do not just colonize the body of mammals during infections. Billions of microbes can be found on and in healthy humans and animals at any given time, communicating with each other via chemical signals and thus influencing their health......»»
Second exoplanet detected orbiting an early G-type star
Astronomers report the detection of a second exoplanet orbiting a G-type star known as TIC 393818343, located some 300 light years away. The newfound alien world is about three times less massive than Jupiter. The finding was detailed in a research p.....»»
Humans have near-equal numbers of male and female babies, unlike many other animals—a new genetic study looks for clues
We know that boys and girls are produced in much the same frequency. But how—and why—is this 1:1 ratio achieved?.....»»
NASA’s Europa Clipper Spacecraft Aims for Jupiter’s Most Intriguing Moon
For the first time, we are sending a spacecraft to explore an alien ocean world—a moon that might host life today.....»»
Trace gas measurements could advance carbon cycle predictions
A novel method for estimating the rate of photosynthesis from land plants reveals that satellite observations—the current gold standard for quantifying terrestrial carbon uptake—underestimate this important metric, a result that could inform and.....»»
What we can learn from animals about death and mortality
Susana Monsó chats with Ars about her new book, Playing Possum: How Animals Understand Death. Human beings live every day with the understanding of our own mortality, but do anim.....»»
In a fusion device plasma, a steep ion temperature gradient slows the growth of magnetic islands
Future fusion power plants will require good plasma confinement to sustain reactions and generate energy. One way to contain plasma for fusion reactions is to use a tokamak, a device that applies magnetic fields to "bottle" plasma. However, magnetic.....»»
