Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com)
Original source 
A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published New soft robots roll like tires, spin like tops and orbit like moons
(via sciencedaily.com)
Original source 
Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.
Published Global study of extreme drought impacts on grasslands and shrublands
(via sciencedaily.com)
Original source 
A global study shows that the effects of extreme drought -- which is expected to increase in frequency with climate change -- has been greatly underestimated for grasslands and shrublands. The findings quantify the impact of extreme short-term drought on grassland and shrubland ecosystems across six continents with a level of detail that was not previously possible. It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.
Published Male southern elephant seals are picky eaters
(via sciencedaily.com)
Original source 
New research suggests these large marine mammals are extremely fussy and only eat their favorite foods.
Published Conflict in full swing: Forest bats avoid large areas around fast-moving wind turbines
(via sciencedaily.com)
Original source 
Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense habitats such as forests drops by almost 80 per cent within a radius of 80 to 450 meters around the turbine.
Published The choreography connecting kelp forests to the beach
(via sciencedaily.com)
Original source 
A new study uncovers a symphony of synchrony between the kelp forest and beach, with broader implications for the beach food web as the climate changes.
Published Microbial awakening restructures high-latitude food webs as permafrost thaws
(via sciencedaily.com)
Original source 
Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.
Published How technology and economics can help save endangered species
(via sciencedaily.com)
Original source 
A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published Could an electric nudge to the head help your doctor operate a surgical robot?
(via sciencedaily.com)
Original source 
People who received gentle electric currents on the back of their heads learned to maneuver a robotic surgery tool in virtual reality and then in a real setting much more easily than people who didn't receive those nudges, a new study shows.
Published Research offers a reason why diversity in plant species causes higher farming yield, solving 'a bit of a mystery'
(via sciencedaily.com)
Original source 
A study appearing in Nature Communications based on field and greenhouse experiments at the University of Kansas shows how a boost in agricultural yield comes from planting diverse crops rather than just one plant species: Soil pathogens harmful to plants have a harder time thriving. While crop rotation and other farming and gardening practices long have reflected benefits of a mix of plants, the new research puts hard data to one important mechanism underpinning the observation: the numbers of microorganisms in the soil that eat plants.
Published Study uncovers major hidden human-driven bird extinctions
(via sciencedaily.com)
Original source 
Humans have wiped out around 1,400 bird species -- twice as many as previously thought -- with major implications for the ongoing biodiversity crisis, a new study has found. The estimated extinctions would mean almost 12 per cent of bird species have died out over modern human history, since the Late Pleistocene around 130,000 years ago, with the vast majority of them becoming extinct directly or indirectly due to human activity.
Published AI's memory-forming mechanism found to be strikingly similar to that of the brain
(via sciencedaily.com)
Original source 
An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
Published Some coral species might be more resilient to climate change than previously thought
(via sciencedaily.com)
Original source 
Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.
Published Hotter weather caused by climate change could mean more mosquitoesv
(via sciencedaily.com)
Original source 
Research along James River in Richmond suggests that climate change could shorten window for predators to prey on larvae.
Published 15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems
(via sciencedaily.com)
Original source 
Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
Published Ecosystem benefits to humanity expected to decline by 9% by 2100
(via sciencedaily.com)
Original source 
A new study of natural capital finds nature's benefits to humanity are expected to decline as climate change shifts ecosystems across borders.
Published Artificial intelligence can predict events in people's lives
(via sciencedaily.com)
Original source 
Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published Move over Blitzen: Geese outpace reindeer impacts on Arctic ecosystems
(via sciencedaily.com)
Original source 
A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the islands.
Published AI provides more accurate analysis of prehistoric and modern animals, painting picture of ancient world
(via sciencedaily.com)
Original source 
A new study of the remains of prehistoric and modern African antelopes found that AI technology accurately identified animals more than 90% of the time compared to humans, who had much lower accuracy rates depending on the expert.
Published AI study reveals individuality of tongue's surface
(via sciencedaily.com)
Original source 
Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest. The results offer an unprecedented insight into the biological make-up of our tongue's surface and how our sense of taste and touch differ from person to person.
