Dinosaurs were the first to take the perspectives of others      (via sciencedaily.com)     Original source 

Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings challenge the idea that mammals were the originators of novel and superior forms of intelligence in the wake of the dinosaur extinction.

Fossils of a saber-toothed top predator reveal a scramble for dominance leading up to 'the Great Dying'      (via sciencedaily.com)     Original source 

A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world's worst mass extinction 252 million years ago. Heading to South Africa allowed it to fill a gap in a faraway ecosystem that had lost its top predators.

Out of the frying pan: Coyotes, bobcats move into human-inhabited areas to avoid apex predators -- only to be killed by people      (via sciencedaily.com)     Original source 

Conservationists have argued that the presence of wolves and other apex predators, so named because they have no known predators aside from people, can help keep smaller predator species in check. New research shows that in Washington state, the presence of two apex predators -- wolves and cougars -- does indeed help keep populations of two smaller predators in check. But by and large the apex predators were not killing and eating the smaller predators, known as mesopredators. Instead, they drove the two mesopredator species -- bobcats and coyotes -- into areas with higher levels of human activity. And people were finishing the job.

Fossil of mosasaur with bizarre 'screwdriver teeth' found in Morocco      (via sciencedaily.com)     Original source 

Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent finds from Africa, it suggests that mosasaurs and other marine reptiles were evolving rapidly up until 66 million years ago, when they were wiped out by an asteroid along with the dinosaurs and around 90% of all species on Earth.

Better than humans: Artificial intelligence in intensive care units      (via sciencedaily.com)     Original source 

With the help of extensive data from intensive care units of various hospitals, an artificial intelligence was developed that provides suggestions for the treatment of people who require intensive care due to sepsis. Analyses show that artificial intelligence already surpasses the quality of human decisions. However, it is now important to also discuss the legal aspects of such methods.

How seaweed has been misleading scientists about reef health      (via sciencedaily.com)     Original source 

For decades, scientists have used the amount of seaweed at the ocean's surface as a proxy for the health of coral reefs below. However, a new global study of more than 1,200 marine locations over a 16-year period reveals that this approach has been misleading -- and may even have hidden signs of reef stress.

Indo-Pacific corals more resilient to climate change than Atlantic corals      (via sciencedaily.com)     Original source 

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.

Joyful music could be a game changer for virtual reality headaches      (via sciencedaily.com)     Original source 

Listening to music could reduce the dizziness, nausea and headaches virtual reality users might experience after using digital devices, research suggests. Cybersickness -- a type of motion sickness from virtual reality experiences such as computer games -- significantly reduces when joyful music is part of the immersive experience, the study found. The intensity of the nausea-related symptoms of cybersickness was also found to substantially decrease with both joyful and calming music.

'Zero plant extinction' is possible, says plant ecologist      (via sciencedaily.com)     Original source 

Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect than animals and play a pivotal role in bolstering our food, fuel, and medical systems. A plant ecologist suggests an approach for preventing all future land plant extinctions across the globe which includes training more plant experts, building an online 'metaherbarium,' and creating 'microreserves.'
