Constructed wetlands are best protection for agricultural runoff into waterways
- ScienceDaily
- 21/7/5 21:21
Researchers found constructed wetlands are the most effective means to improve water quality, especially if the size and location are evaluated at the scale of a watershed -- an entire region that drains into a common waterway.
Male dragonflies lose their 'bling' in hotter climates
- ScienceDaily
- 21/7/5 21:21
A new study finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates. The research reveals that mating-related traits can be just as important to how organisms adapt to their climates as survival-related traits.

Nanomaterials shape and form influences their ability to cross the blood brain barrier
- ScienceDaily
- 21/7/5 21:20
Nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape - creating potential neurological impacts that could be both positive and negative, a new study reveals.
Software evaluates qubits, characterizes noise in quantum annealers
High-performance computer users in the market for a quantum annealing machine or looking for ways to get the most out of one they already have will benefit from a new, open-source software tool for evaluating these emerging platforms at the individual qubit level.
Sculpted by starlight: A meteorite witness to the solar system's birth
In 2011, scientists confirmed a suspicion: There was a split in the local cosmos. Samples of the solar wind brought back to Earth by the Genesis mission definitively determined oxygen isotopes in the sun differ from those found on Earth, the moon and the other planets and satellites in the solar system.
Constructed wetlands are best protection for agricultural runoff into waterways
A new paper from a lead author based at the University of Kansas finds wetlands constructed along waterways are the most cost-effective way to reduce nitrate and sediment loads in large streams and rivers. Rather than focusing on individual farms, the research suggests conservation efforts using wetlands should be implemented at the watershed scale.
Male dragonflies lose their 'bling' in hotter climates
A study published the week of July 5 in the Proceedings of the National Academy of Sciences led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates.

A vast seabird colony on Ascension Island creates a "halo" in which fewer fish live, new research shows.
Fossil shark scales provide a glimpse of reef predator populations before human impact
Scientists recently made news by using fossil shark scales to reconstruct shark communities from millions of years ago. At the same time, an international team of researchers led by UC Santa Barbara ecologist Erin Dillon applied the technique to the more recent past.
How fish got their spines
In the movie "A Fish Called Wanda," the villain Otto effortlessly gobbles up all the occupants of Ken`s fish tank. Reality, however, is more daunting. At least one unfortunate fan who re-enacted this scene was hospitalized with a fish stuck in the throat. This was also was a painful lesson in ichthyology (the scientific study of fishes)—namely that the defense of some fishes consists of...
Ancient bone carving could change the way we think about Neanderthals
The design may be simple, but a chevron pattern etched onto a deer bone more than 50,000 years ago suggests that Neanderthals had their own artistic tradition before modern humans arrived on the scene, researchers said Monday.
Chris Whitty suggests guidelines for use of masks after 19 July

Global BECCS potential is largely constrained by sustainable irrigation
- ScienceDaily
- 21/7/5 17:39
Bioenergy with Carbon Capture and Storage (BECCS), a negative emission technology, has been considered inevitable to achieve the 2°C or 1.5°C climate goal. Although numerous studies have been conducted, the effect of irrigation remains largely unexplored when taking water use sustainability into consideration. A new study finds that although unlimited irrigation could increase the global BECCS...
Psychedelic spurs growth of neural connections lost in depression
- ScienceDaily
- 21/7/5 17:39
In a new study, researchers show that a single dose of psilocybin given to mice prompted an immediate and long-lasting increase in connections between neurons. The findings are published July 5 in the journal Neuron.
Astronomers discover an oversized black hole population in the star cluster Palomar 5
- ScienceDaily
- 21/7/5 17:39
Palomar 5 is a unique star cluster. In a new paper, astrophysicists show that distinguishing features of Palomar 5 are likely the result of an oversized black hole population of more than 100 of them in the center of the cluster.
Belowground microbial solutions to aboveground plant problems

- 21/7/5 17:39
Researchers have discovered that signaling occurring from the response of plant leaves to light, and plant roots to microbes, is integrated along a microbiota-root-shoot axis to boost plant growth when light conditions are suboptimal.
Climate change: Planting extra trees will boost rainfall across Europe
Converting agricultural land to forestry would boost summer rains by 7.6% on average, a study finds.
Underground microbial solutions to aboveground plant problems
Land plants—those that live primarily in terrestrial habitats and form vegetation—are anchored to the ground through their roots, and their performance depends on both the underground soil conditions and the aboveground climate. Plants use sunlight to grow through the process of photosynthesis where light energy is converted to chemical energy in chloroplasts, the powerhouses of plant cells....

In a paper published today in Nature Astronomy, an international team of astrophysicists led by the University of Barcelona show that distinguishing features of Palomar 5 are likely the result of an oversized black hole population of more than 100 of them in the center of the cluster.
Climate crisis causing male dragonflies to lose wing ‘bling’, study finds
Black patterns used to attract mates can cause the insects to overheat in hotter climatesMale dragonflies are losing the “bling” wing decorations that they use to entice the females as climates get hotter, according to new research.The results have led to the scientists calling for more work on whether this disparate evolution might lead to females no longer recognising males of their own...
Global BECCS potential is largely constrained by sustainable irrigation
A new collaborative study led by researchers from the National Institute for Environmental Studies, Potsdam Institute for Climate Impact Research, Ritsumeikan University, and Kyoto University found that although unlimited irrigation could increase global BECCS potential (via the increase of bioenergy production) by 60-71% by the end of this century, sustainably constrained irrigation would...
