Humans need Earth-like ecosystem for deep-space living      (via sciencedaily.com)     Original source 

Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.

In Florida study, nonnative leaf-litter ants are replacing native ants      (via sciencedaily.com)     Original source 

A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.

AI-equipped eyeglasses read silent speech      (via sciencedaily.com)     Original source 

Researchers have developed a silent-speech recognition interface that uses acoustic-sensing and artificial intelligence to continuously recognize up to 31 unvocalized commands, based on lip and mouth movements.

Coral skeletons influence reef recovery after bleaching      (via sciencedaily.com)     Original source 

Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.

Detecting, predicting, and preventing aortic ruptures with computational modeling      (via sciencedaily.com)     Original source 

According to some estimates, up to 80% of patients who experience a ruptured abdominal aortic aneurysm will die before they reach the hospital or during surgery. But early intervention can prevent rupture and improve outcomes. Researchers have now made a computational model of the cardiovascular system in order to predict early AAA rupture and monitor patients' blood vessel conditions. They mimicked specific health conditions and investigated various hemodynamic parameters using image-based computational blood dynamics.

Innovative method predicts the effects of climate change on cold-blooded animals      (via sciencedaily.com) 

In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.

Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk      (via sciencedaily.com) 

Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.

Smart films help to make loudspeakers lighter and more energy-efficient      (via sciencedaily.com)     Original source 

Scientists are developing intelligent materials that are opening up new avenues in sound reproduction technology: lightweight loudspeakers that use far less energy than their conventional counterparts, novel shapes for sound and signal generators and applications involving noise cancelling textiles. The basis for these smart materials are ultrathin silicone films that can act as artificial muscles with their own built-in sensors.

Hope for salamanders? Study recalibrates climate change effects      (via sciencedaily.com) 

For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.

Scientists discover hidden crab diversity among coral reefs      (via sciencedaily.com) 

The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.

Most of world's salt marshes likely to be underwater by 2100, study concludes      (via sciencedaily.com) 

Salt marshes are some of the most biologically productive ecosystems on Earth. They play an outsized role in nitrogen cycling, act as carbon sinks, protect coastal development from storm surge, and provide critical habitats and nurseries for many fish, shellfish, and coastal birds. According to new research, more than 90 percent of the world's salt marshes are likely to be underwater by the end of the century. These findings come from a 50-year study of ecosystem changes in Great Sippewissett Marsh in Falmouth, Mass.

Pulsing ultrasound waves could someday remove microplastics from waterways      (via sciencedaily.com) 

Colorful particles of plastic drift along under the surface of most waterways. These barely visible microplastics -- less than 5 mm wide -- are potentially harmful to aquatic animals and plants, as well as humans. Now, a team reports a two-stage device made with steel tubes and pulsing sound waves that removes most of the plastic particles from real water samples.

Even Sonoran Desert plants aren't immune to climate change      (via sciencedaily.com) 

In North America's hottest, driest desert, climate change is causing the decline of plants once thought nearly immortal and replacing them with shorter shrubs that can take advantage of sporadic rainfall and warmer temperatures.

What do the elements sound like?      (via sciencedaily.com) 

In chemistry, we have He, Fe and Ca -- but what about do, re and mi? Using a technique called data sonification, a recent college graduate has converted the visible light given off by each of the elements into soundwaves. The notes produced for each element are unique, complex mixtures and are the first step toward an interactive, musical periodic table.

Habitat will dictate whether ground beetles win or lose against climate change      (via sciencedaily.com) 

The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.

Road noise makes your blood pressure rise -- literally      (via sciencedaily.com) 

If you live near a busy road you might feel like the constant sound of roaring engines, honking horns and wailing sirens makes your blood pressure rise. Now a new study confirms it can do exactly that.
