Light-controlled artificial maple seeds could monitor the environment even in hard-to-reach locations      (via sciencedaily.com)     Original source 

Researchers have developed a tiny robot replicating the aerial dance of falling maple seeds. In the future, this robot could be used for real-time environmental monitoring or delivery of small samples even in inaccessible terrain such as deserts, mountains or cliffs, or the open sea. This technology could be a game changer for fields such as search-and-rescue, endangered species studies, or infrastructure monitoring.

Projected loss of brown macroalgae and seagrasses with global environmental change      (via sciencedaily.com)     Original source 

Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.

Wolves reintroduced to Isle Royale temporarily affect other carnivores, humans have influence as well      (via sciencedaily.com)     Original source 

In a rare opportunity to study carnivores before and after wolves were reintroduced to their ranges, researchers found that the effects of wolves on Isle Royale have been only temporary. And even in the least-visited national park, humans had a more significant impact on carnivores' lives.

Robots face the future      (via sciencedaily.com)     Original source 

Researchers have found a way to bind engineered skin tissue to the complex forms of humanoid robots. This brings with it potential benefits to robotic platforms such as increased mobility, self-healing abilities, embedded sensing capabilities and an increasingly lifelike appearance. Taking inspiration from human skin ligaments, the team included special perforations in a robot face, which helped a layer of skin take hold.

Fuel treatments reduce future wildfire severity      (via sciencedaily.com)     Original source 

There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.

Boosting biodiversity without hurting local economies      (via sciencedaily.com)     Original source 

Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.

Non-native plants and animals expanding ranges 100 times faster than native species      (via sciencedaily.com)     Original source 

An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.

When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change      (via sciencedaily.com)     Original source 

Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.

Natural hazards threaten over three thousand species      (via sciencedaily.com)     Original source 

Natural hazards can speed up the extinction process of land animals that have limited distribution and/or small populations. But there is hope to turn the negative development around, says researchers behind new study.

Breakthrough approach enables bidirectional BCI functionality      (via sciencedaily.com)     Original source 

Brain-computer interfaces or BCIs hold immense potential for individuals with a wide range of neurological conditions, but the road to implementation is long and nuanced for both the invasive and noninvasive versions of the technology. Scientists have now successfully integrated a novel focused ultrasound stimulation to realize bidirectional BCI that both encodes and decodes brain waves using machine learning in a study with 25 human subjects. This work opens up a new avenue to significantly enhance not only the signal quality, but also, overall nonivasive BCI performance by stimulating targeted neural circuits.

Marine heatwaves devastate red gorgonians in the Medes Islands      (via sciencedaily.com)     Original source 

The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.

Mobile monitoring for an airborne carcinogen in Louisiana's 'Cancer Alley'      (via sciencedaily.com)     Original source 

Louisiana's southeastern corridor is sometimes known colloquially as 'Cancer Alley' for its high cancer incidence rates connected to industrial air pollution. Most of the region's air pollution-related health risks are attributed to ethylene oxide, a volatile compound used to make plastics and sterilize medical equipment. Researchers measured concerning levels of ethylene oxide in this area with mobile optical instruments, a technique they say could improve health risk assessments.
