Two artificial intelligences talk to each other      (via sciencedaily.com)     Original source 

Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team has succeeded in modelling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a 'sister' AI, which in turn performed them.

Holographic message encoded in simple plastic      (via sciencedaily.com)     Original source 

Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used to produce a panel from normal plastic in which a QR code can be stored, for example. The message is read using terahertz rays -- electromagnetic radiation that is invisible to the human eye.

Fish species that move rapidly toward the poles due to global warming decline in abundance, study finds      (via sciencedaily.com)     Original source 

A new study has found a decline in the abundance of marine fish species that move rapidly toward the poles to escape rising sea temperatures. The researchers explain that many animal species are currently moving toward cooler regions as a result of global warming, but the velocity of such range shifts varies greatly for different species. Examining thousands of populations from almost 150 fish species, the researchers show that contrary to the prevailing view, rapid range shifts coincide with widescale population declines.

Eyes open and toes out of water: How a giant water bug reached the island of Cyprus      (via sciencedaily.com)     Original source 

A new visitor was reported on the coast of Cyprus, thanks to the growing power of citizen science. Researchers collected information and specimens through personal communication with amateur naturalists, but also through the internet, in order to compose the mosaic of repeated appearances of a giant water bug on the eastern shoreline of the island.

New technique helps AI tell when humans are lying      (via sciencedaily.com)     Original source 

Researchers have developed a new training tool to help artificial intelligence (AI) programs better account for the fact that humans don't always tell the truth when providing personal information. The new tool was developed for use in contexts when humans have an economic incentive to lie, such as applying for a mortgage or trying to lower their insurance premiums.

Global wildlife study during COVID-19 shows rural animals are more sensitive to human activity      (via sciencedaily.com)     Original source 

One of the largest studies on wildlife activity reveals that wild animals react differently to humans depending on where the animals live and what they eat. Bigger herbivores -- plant-eating animals like deer or moose -- tend to become more active when humans are around, while meat-eaters like wolves or wolverines tend to be less active, preferring to avoid risky encounters.

Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale      (via sciencedaily.com)     Original source 

Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.

Tropical birds could tolerate warming better than expected, study suggests      (via sciencedaily.com)     Original source 

We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.

Sleep-wake rhythm: Fish change our understanding of sleep regulation      (via sciencedaily.com)     Original source 

Researchers have discovered that some fish -- unlike humans -- do not need orexin to stay awake. This molecule was thought to be necessary for normal wake and sleep rhythms in vertebrates. Humans without orexin suffer from narcolepsy.

Training dairy cows with positive reinforcement can turn otherwise stressful events into play      (via sciencedaily.com)     Original source 

Dairy cows receive a huge amount of care during their lives on a farm, but procedures, especially restraining during procedures, can be stressful for some animals. Positive reinforcement training -- or training with a reward to achieve a desired behavior -- has shown promise to reduce this fear in other species.

With discovery of roundworms, Great Salt Lake's imperiled ecosystem gets more interesting      (via sciencedaily.com)     Original source 

Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.
