You say genome editing, I say natural mutation      (via sciencedaily.com)     Original source 

A plant geneticist and computational biologist teamed up to decipher the unpredictability of natural and engineered mutations in tomatoes. They discovered some combinations of mutations behave as expected while others are more erratic. Their work may help scientists find some order in the chaos of evolution and genome editing.

Heat waves harm bird reproduction on agricultural lands      (via sciencedaily.com)     Original source 

The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.

Imprinted genes in the 'parenting hub' of the brain determine if mice are good parents      (via sciencedaily.com)     Original source 

Whether a mouse is a good or bad parent can be traced back to imprinted genes in key neurons in the 'parenting hub' in the brain, according to a new study.

Stolen genes allow parasitic control of behavior      (via sciencedaily.com)     Original source 

A research team has discovered that parasites manipulate their hosts using stolen genes that they likely acquired through a phenomenon called horizontal gene transfer.

Pinpointing the emergence of muddy flavors in your fish      (via sciencedaily.com)     Original source 

Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.

Biodegradable plastics still damaging to fish      (via sciencedaily.com)     Original source 

Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.

New insights into the genetics of the common octopus: Genome at the chromosome level decoded      (via sciencedaily.com)     Original source 

Octopuses are fascinating animals -- and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now. Scientists have now been able to close this gap and, in a new study, determined impressive figures: 2.8 billion base pairs -- organized in 30 chromosomes. What sounds so simple is the result of complex, computer-assisted genome analyses and comparisons with the genomes of other cephalopod species.

Whaling wiped out far more fin whales than previously thought      (via sciencedaily.com)     Original source 

Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population.

Orchid without bumblebee on island finds wasp, loses self      (via sciencedaily.com)     Original source 

Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances.

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.

Scientists, philosophers identify nature's missing evolutionary law      (via sciencedaily.com)     Original source 

A new article describes 'a missing law of nature,' recognizing for the first time an important norm within the natural world's workings.   In essence, the new law states that complex natural systems evolve to states of greater patterning, diversity, and complexity. In other words, evolution is not limited to life on Earth, it also occurs in other massively complex systems, from planets and stars to atoms, minerals, and more.

Extinct ape gets a facelift, 12 million years later      (via sciencedaily.com)     Original source 

A new study has reconstructed the well-preserved but damaged skull of a great ape species that lived about 12 million years ago. The species, Pierolapithecus catalaunicus, may be crucial to understanding great ape and human evolution.

200-year-old DNA helps map tiny fly's genetic course to new lands, modern times      (via sciencedaily.com)     Original source 

Researchers have extracted and analyzed DNA from fruit flies housed in museum collections in Lund, Stockholm and Copenhagen. Surprisingly, the researchers found the fruit flies collected in Sweden in the early 1800s were more genetically similar to 21st century flies than the Swedish samples from the 1930s.
