Bite this! Mosquito feeding chamber uses fake skin, real blood      (via sciencedaily.com) 

Bioengineers and experts in tropical medicine have invented a new way of studying mosquito feeding behavior using technology instead of live volunteers. Their open-source design combines automated cameras, artificial intelligence and blood-infused, 3D-printed 'synthetic skin.'

Endangered Bahamas bird may be lost from island following hurricane      (via sciencedaily.com) 

The endangered Bahama Warbler may be surviving on just one island following Hurricane Dorian's devastation in 2019, according to researchers. A new study shows the bird's distribution and ecology on Grand Bahama before the hurricane struck. But the team says that the warbler may now only survive on neighboring Abaco island, after hurricane Dorian destroyed the bird's forest habitat on Grand Bahama. The research comes from the same team that found what is thought to have been the last living Bahama Nuthatch, previously thought to have been extinct.

Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time      (via sciencedaily.com) 

New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.

Loss of reptiles poses threat for small islands where humans may have caused extinctions      (via sciencedaily.com) 

A new examination of ancient and current species of reptiles conducted by paleobiologists reveals the serious impact of the disappearance of even a few species of reptiles in some island areas. The study has startling conclusions about how, on smaller islands in the Caribbean where human impact was greatest, extinctions have led to the loss of up to two-thirds of the supports for the ecosystem that native reptile species once provided there.

Interactive cyber-physical human: Generating contact-rich whole-body motions      (via sciencedaily.com) 

Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.

Voiceless frog discovered in Tanzania      (via sciencedaily.com)     Original source 

Researchers discovered a new species of frog in Africa that has an unusual trait: it's completely silent. The Ukaguru spiny-throated reed frog does not croak, sing or ribbit. Found in Tanzania's Ukaguru Mountains for which it is named, Hyperolius ukaguruensis is among the few frogs around the world that do not vocalize to other frogs.

Climate change may cut US forest inventory by a fifth this century      (via sciencedaily.com)     Original source 

A study found that under more severe climate warming scenarios, the inventory of trees used for timber in the continental United States could decline by as much as 23% by 2100. The largest inventory losses would occur in two of the leading timber regions in the U.S., which are both in the South.

Protected areas fail to safeguard more than 75% of global insect species      (via sciencedaily.com) 

Insects play crucial roles in almost every ecosystem -- they pollinate more than 80% of plants and are a major source of food for thousands of vertebrate species -- but insect populations are collapsing around the globe, and they continue to be overlooked by conservation efforts. Protected areas can safeguard threatened species but only if these threatened species actually live within the areas we protect. A new study found that 76% of insect species are not adequately covered by protected areas.

Contributing to the utilization of big data! Developing new data learning methods for artificial intelligence      (via sciencedaily.com) 

A research group has developed a new learning method for artificial intelligence that combines classification performance for data with multiple labels with the ability to learn continually from data. Numerical experiments on real-world multi-label data indicate that the new method outperforms conventional approaches. The simplicity of this algorithm makes it easy to integrate it with other algorithms to devise new ones.
