How flies develop sight: Scientists use single-cell sequencing to identify cell types in the visual system      (via sciencedaily.com)     Original source 

Researchers have discovered new cell types in the visual system of flies, made possible by their creation of a tool that finds and labels neurons during development. The study combines single-cell sequencing data with a novel algorithm to identify pairs of genes that point to previously unknown cells in the brains of fruit flies.

Plans to plant billions of trees threatened by massive undersupply of seedlings      (via sciencedaily.com)     Original source 

Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.

Scientists discover secret of virgin birth, and switch on the ability in female flies      (via sciencedaily.com)     Original source 

Scientists have pinpointed a genetic cause for virgin birth for the first time, and once switched on the ability is passed down through generations of females.

Cell biology: How cellular powerhouses call for help when under stress      (via sciencedaily.com)     Original source 

Originally, the powerhouses of higher cells, the mitochondria, were independent organisms. Researchers have investigated to what extent their metabolism has blended with that of their host cells in the course of evolution, using the example of a mitochondrial stress response. They have discovered that mitochondria send two different biochemical signals. These are processed together in the cell and trigger a support mechanism to restore cellular balance (homeostasis).

Alternative cellular 'fuels' boost immunity      (via sciencedaily.com)     Original source 

A metabolic by-product that is more prevalent during fasting may supercharge immune cells as they fight infection and disease, reports an early stage study. The findings may pave the way for future personalized dietary recommendations to augment treatments for infection, cancer and other diseases.

Scientists vacuum animal DNA from air in a Danish forest      (via sciencedaily.com)     Original source 

Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.

Researchers develop 'in vivo' RNA-based gene editing model for blood disorders      (via sciencedaily.com)     Original source 

In a step forward in the development of genetic medicines, researchers have developed a proof-of-concept model for delivering gene editing tools to treat blood disorders, allowing for the modification of diseased blood cells directly within the body. If translated into the clinic, this approach could expand access and reduce the cost of gene therapies for blood disorders, many of which currently require patients receive chemotherapy and a stem cell transplant.

Fast electrical signals mapped in plants with new bioelectronic technology      (via sciencedaily.com)     Original source 

What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress.

Aphids make tropical milkweed less inviting to monarch butterflies      (via sciencedaily.com)     Original source 

When oleander aphids infested tropical milkweed, monarch butterflies laid fewer eggs on the plant, and the caterpillars developing on those plants were slower to mature.

Climate change threatens 771 endangered plant and lichen species      (via sciencedaily.com)     Original source 

All plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change but there are few plans in place to address this threat directly, according to new research.

Lifespan of aging science's model organism driven by reproductive self-destruction      (via sciencedaily.com)     Original source 

The lifespan of a small roundworm that has been used as a key model organism in aging research is limited by how it self-sacrifices to feed its young, finds a new study.

Genetic study reveals that a captive-bred population could save endangered crocodile from extinction      (via sciencedaily.com)     Original source 

Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.

Missing island explains how endemic species on the Miyako Islands emerged      (via sciencedaily.com)     Original source 

Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.
