How to help save plants from extinction      (via sciencedaily.com)     Original source 

Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.

Genomic analysis in snakes shows link between neutral, functional genetic diversity      (via sciencedaily.com)     Original source 

In the world of threatened and endangered species conservation, the genomic revolution has raised some complicated questions: How can scientists justify assessing species genetic diversity without consulting entire genomes now that they can be sequenced? But then again, how can scientists justify the time and expense of genome sequencing when age-old measures of neutral genetic diversity are much cheaper and easier to obtain? A new study suggests making a transition from 'old school' genetics to 'new school' genomics for species conservation purposes probably isn't necessary in all cases.

Deep neural networks don't see the world the way we do      (via sciencedaily.com)     Original source 

Computational models of hearing and vision can build up their own idiosyncratic 'invariances' -- meaning they respond the same way to stimuli with very different features, according to scientists.

New organ-on-a-chip model of human synovium could accelerate development of treatments for arthritis      (via sciencedaily.com)     Original source 

The synovium is a membrane-like structure that lines the knee joint and helps to keep the joint happy and healthy, mainly by producing and maintaining synovial fluid. Inflammation of this tissue is implicated in the onset and progression of arthritic diseases such as rheumatoid and osteoarthritis. Therefore, treatments that target the synovium are promising in treating these diseases. However, we need better models in the laboratory that allow us to find and test new treatments. We have developed an organ-on-a-chip based model of the human synovium, and its associated vasculature, to address this need.

Bouldering in south-central Madagascar: A new 'rock-climbing' gecko species of the genus Paroedura      (via sciencedaily.com)     Original source 

A new Paroedura gecko species was reported at two small forest sites, Anja Reserve and Tsaranoro Valley forest, in the south-central plateau of Madagascar. Thanks to the recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites. Its conservation status was evaluated as Critically Endangered given its tiny distributional range.

A step towards AI-based precision medicine      (via sciencedaily.com)     Original source 

Artificial intelligence, AI, which finds patterns in complex biological data could eventually contribute to the development of individually tailored healthcare. Researchers have developed an AI-based method applicable to various medical and biological issues. Their models can for instance accurately estimate people's chronological age and determine whether they have been smokers or not.

Mummified feces reveals pre-Columbian cultures of the Caribbean consumed a diversity of plants      (via sciencedaily.com)     Original source 

DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.

Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats      (via sciencedaily.com)     Original source 

Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.

Killing remains a threat to Bornean orangutans      (via sciencedaily.com)     Original source 

New research has found despite considerable conservation efforts, the illegal killing of critically endangered orangutans on Borneo may be an ongoing threat to the species.

What is the impact of predictive AI in the health care setting?      (via sciencedaily.com)     Original source 

Models built on machine learning in health care can be victims of their own success, according to researchers. Their study assessed the impact of implementing predictive models on the subsequent performance of those and other models.

Ancient Maya reservoirs offer lessons for today's water crises      (via sciencedaily.com)     Original source 

Ancient Maya reservoirs, which used aquatic plants to filter and clean the water, 'can serve as archetypes for natural, sustainable water systems to address future water needs.' The Maya built and maintained reservoirs that were in use for more than 1,000 years. These reservoirs provided potable water for thousands to tens of thousands of people in cities during the annual, five-month dry season and in periods of prolonged drought.

Researchers create a neural network for genomics -- one that explains how it achieves accurate predictions      (via sciencedaily.com)     Original source 

A team of computer scientists has created a neural network that can explain how it reaches its predictions. The work reveals what accounts for the functionality of neural networks--the engines that drive artificial intelligence and machine learning--thereby illuminating a process that has largely been concealed from users.

Fear of humans pervades the South African savanna      (via sciencedaily.com)     Original source 

Mammals living in South Africa's Greater Kruger National Park, home to one of the world's largest remaining lion populations, are far more afraid of hearing human voices than lion vocalizations or hunting sounds such as dogs barking or gunshots.

Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought      (via sciencedaily.com)     Original source 

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
