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.

An electrical switch to control chemical reactions      (via sciencedaily.com)     Original source 

New pharmaceuticals, cleaner fuels, biodegradable plastics: in order to meet society's needs, chemists have to develop new synthesis methods to obtain new products that do not exist in their natural state. A research group has discovered how to use an external electric field to control and accelerate a chemical reaction, like a 'switch'. This work could have a considerable impact on the development of new molecules, enabling not only more environmentally friendly synthesis, but also very simple external control of a chemical reaction.

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.

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.

Newly-discovered 'margarita snails' from the Florida Keys are bright lemon-yellow      (via sciencedaily.com)     Original source 

A newly-discovered, bright yellow snail has been discovered in the Florida Keys and named in honor of Jimmy Buffet's song 'Margaritaville.' The lemon-colored marine snail, along with its lime-green cousin from Belize, is the subject of a recent study ; researchers think these snails' bright colors might help deter predators.

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.

Discovery made about Fischer Tropsch process could help improve fuel production      (via sciencedaily.com)     Original source 

A fundamental discovery about the Fischer Tropsch process, a catalytic reaction used in industry to convert coal, natural gas or biomass to liquid fuels, could someday allow for more efficient fuel production. Researchers discovered previously unknown self-sustained oscillations in the Fischer Tropsch process. They found that unlike many catalytic reactions which have one steady state, this reaction periodically moves back and forth from a high to a low activity state. The discovery means that these well-controlled oscillatory states might be used in the future to control the reaction rate and the yields of desired products.

The medicine of the future could be artificial life forms      (via sciencedaily.com)     Original source 

Imagine a life form that doesn't resemble any of the organisms found on the tree of life. One that has its own unique control system, and that a doctor would want to send into your body. It sounds like a science fiction movie, but according to nanoscientists, it can—and should—happen in the future.

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.

Ruffed grouse population more resilient than expected, genetic study finds      (via sciencedaily.com)     Original source 

Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented.

Graphene oxide reduces the toxicity of Alzheimer's proteins      (via sciencedaily.com)     Original source 

A probable early driver of Alzheimer's disease is the accumulation of molecules called amyloid peptides. These cause cell death, and are commonly found in the brains of Alzheimer’s patients. Researchers have now shown that yeast cells that accumulate these misfolded amyloid peptides can recover after being treated with graphene oxide nanoflakes.
