Unlocking the genetic code of peppers: New study reveals insights into domestication and diversity      (via sciencedaily.com)     Original source 

Peppers are a versatile, flavorful, and widely popular crop, used not only as a healthy food source but also for their medicinal properties. Scientists have now sequenced the genomes of key cultivated and wild pepper species, offering unprecedented insights into pepper evolution, domestication, and genetic diversity.

Fall snow levels can predict a season's total snowpack in some western states      (via sciencedaily.com)     Original source 

Research found that, in some western states, the amount of snow already on the ground by the end of December is a good predictor of how much total snow that area will get.

Hot summer air turns into drinking water with new gel device      (via sciencedaily.com) 

Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.

You say tomato, these scientists say evolutionary mystery      (via sciencedaily.com)     Original source 

Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.

Lions on the brink -- New analysis reveals the differing threats to African lion populations      (via sciencedaily.com)     Original source 

New results reveal that many of Africa's remaining lions live within small, fragmented populations at risk of disappearing. The researchers developed a new framework which integrates ecological and socio-political risk factors to better understand the fragility of these populations.

'A crab is never just a crab'      (via sciencedaily.com)     Original source 

A herring in the North Sea, a crab in the Wadden Sea or an anemone fish on a coral reef, ... biologists like to think in terms of individual species that all have their own place within food webs in ecosystems across the world. 'But that is surely too simplistic thinking,' researchers warn.

Jackdaws switch friends to gain food -- but stick with family      (via sciencedaily.com)     Original source 

Jackdaws ditch old friends and make new ones if it helps them get rewards -- but stick with family through thick and thin, new research shows.

Disease affects blackbirds more than previously thought      (via sciencedaily.com)     Original source 

When humans are ill, we tend to be less active. This also applies to wild animals, but so far, it has not been known how long the reduced activity lasts or which activities are affected the most. New research shows that birds' activity decreases for up to three weeks when they become ill -- something that could mean the difference between life and death.

Human shoulders and elbows first evolved as brakes for climbing apes      (via sciencedaily.com)     Original source 

Researchers report that the flexible shoulders and elbows that allow us to throw a football or reach a high shelf may have evolved as a natural braking system that let our primate ancestors get out of trees without dying. The researchers used sports-analysis software to compare the climbing movements of chimpanzees and small monkeys called mangabeys. While the animals climb up trees similarly, the researchers found that the shallow, rounded shoulder joints and shortened elbow bones that chimps have -- similar to humans -- allow them to fully extend their arms above their heads when climbing down, holding onto branches like a person going down a ladder to support their greater weight. When early humans left forests for the grassy savanna, these versatile appendages would have been essential for gathering food and using tools for hunting and defense. The findings are among the first to identify the significance of 'downclimbing' in the evolution of apes and early humans.

Large herbivores keep invasive plants at bay      (via sciencedaily.com) 

Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.
