Federal environmental laws are failing to mitigate against Australia's extinction crisis, according to new research.

Researchers report that elephants play a key role in creating forests which store more atmospheric carbon and maintaining the biodiversity of forests in Africa. If the already critically endangered elephants become extinct, rainforest of central and west Africa, the second largest rainforest on earth, would lose between six and nine percent of their ability to capture atmospheric carbon, amplifying planetary warming.

One of the virtues of untethered soft robots is their ability to mechanically adapt to their surroundings and tasks. Now they are poised to become even more agile and controlled.

Protected natural areas of the UK are struggling to halt declines in insects and spiders that have occurred over the past 30 years, according to a new study.

Intact forests are important climate regulators and harbors of biodiversity, but they are rapidly disappearing. Agriculture is commonly considered to be the major culprit behind forest loss, but the authors of a new article show that agriculture isn't solely to blame. For forest loss associated with the 2014 world economy, over 60% was related to final consumption of non-agricultural products, such as minerals, metals and wood-related goods, and the authors argue that we must consider international trade markets when designing conservation strategies.

In order to meet climate protection goals, renewable energies are booming -- often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential sites. A scientific team has now demonstrated that wind turbines in forests impair endangered bat species: Common noctules (Nyctalus noctula), a species with a high risk of colliding with rotor blades, are attracted to forest wind turbines if these are located near their roosts. Far from roosts, common noctules avoid the turbines, essentially resulting in a loss of foraging space and thus habitat for this species.

For people who are blind or visually impaired, finding the right products in a crowded grocery store can be difficult without help. A team of computer scientists is trying to change that.

Flooding in Australia's Murray-Darling Basin is creating ideal breeding conditions for many native species that have evolved to take advantage of temporary flood conditions. Scientists have now developed virtual models of the Murray River to reveal a crucial link between natural flooding and the extinction risk of endangered southern bell frogs (Litoria raniformis; also known as growling grass frogs). Southern bell frogs are one of Australia's 100 Priority Threatened Species. This endangered frog breeds during spring and summer when water levels increase in their wetlands. However, the natural flooding patterns in Australia's largest river system have been negatively impacted by expansive river regulation that in some years, sees up to 60% of river water extracted for human use.

Until now, microscopic robotic systems have had to make do without arms. Now researchers have developed an ultrasonically actuated glass needle that can be attached to a robotic arm. This lets them pump and mix minuscule amounts of liquid and trap particles.

Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones.

A study is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of theropods -- a dinosaur group that includes both modern birds and their closest non-avian dinosaur relatives -- from the Chilean portion of Patagonia. The researchers' finds include giant megaraptors with large sickle-like claws and birds similar to todays ducks and geese.

Only a fraction of the 7,000 to 8,000 languages spoken around the world benefit from modern language technologies like voice-to-text transcription, automatic captioning, instantaneous translation and voice recognition. Researchers want to expand the number of languages with automatic speech recognition tools available to them from around 200 to potentially 2,000.

The artificial intelligence algorithms behind the chatbot program ChatGPT -- which has drawn attention for its ability to generate humanlike written responses to some of the most creative queries -- might one day be able to help doctors detect Alzheimer's Disease in its early stages. Research recently demonstrated that OpenAI's GPT-3 program can identify clues from spontaneous speech that are 80% accurate in predicting the early stages of dementia.

What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.

Humans displaying positive emotions in customer service interactions have long been known to improve customer experience, but researchers wanted to see if this also applied to AI. They conducted experimental studies to determine if positive emotional displays improved customer service and found that emotive AI is only appreciated if the customer expects it, and it may not be the best avenue for companies to invest in.

A small tax on robots, as well as on trade generally, will help reduce income inequality in the U.S., according to economists.

Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.
