Research offers a reason why diversity in plant species causes higher farming yield, solving 'a bit of a mystery'      (via sciencedaily.com)     Original source 

A study appearing in Nature Communications based on field and greenhouse experiments at the University of Kansas shows how a boost in agricultural yield comes from planting diverse crops rather than just one plant species: Soil pathogens harmful to plants have a harder time thriving. While crop rotation and other farming and gardening practices long have reflected benefits of a mix of plants, the new research puts hard data to one important mechanism underpinning the observation: the numbers of microorganisms in the soil that eat plants.

Mysterious fruit shown to be the oldest known fossils of the Frankincense and Myrrh family      (via sciencedaily.com)     Original source 

Early in the 1970s, paleontologists discovered strange fossilized fruits between hardened rock from one of the largest volcanic eruptions in Earth's history. The identity of these fossils remained elusive for the next several decades. Using CT scanning, scientists have now determined they are the oldest fossils from species in the Frankincense and Myrrh family.

Genetics of host plants determine what microorganisms they attract      (via sciencedaily.com)     Original source 

Plants often develop communities with microorganisms in their roots, which influences plant health and development. Although the recruitment of these microbes is dictated by several factors, it is unclear whether the genetic variation in the host plants plays a role.

AI provides more accurate analysis of prehistoric and modern animals, painting picture of ancient world      (via sciencedaily.com)     Original source 

A new study of the remains of prehistoric and modern African antelopes found that AI technology accurately identified animals more than 90% of the time compared to humans, who had much lower accuracy rates depending on the expert.

Trees in wetter regions more sensitive to drought      (via sciencedaily.com)     Original source 

This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it's likely been spoiled for generations.

How forests smell -- a risk for the climate?      (via sciencedaily.com)     Original source 

Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.

Why the long face? Scientists solve a major puzzle in mammal skull shape evolution      (via sciencedaily.com)     Original source 

Horses have developed long faces simply 'because they can,' a team of evolutionary biologists say. In a major review of how mammalian heads evolve, scientists found that adaptations to feeding explain why large species of mammals often have much longer faces compared to smaller closely related species -- a pattern referred to as Craniofacial Evolutionary Allometry (CREA).

A new brew: Evaluating the flavor of roasted, lab-grown coffee cells      (via sciencedaily.com)     Original source 

It may soon be time to wake up and smell the lab-grown coffee made from cultured plant cells. But it's not clear whether drinks from this product replicate coffee beans' complex flavors. Now, a study found that some of the comforting aromas and tastes of a conventional cup of coffee could be reproduced by roasting and brewing coffee cell cultures.

Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.

Urbanization increases seasonal differences in plant-pollinator networks      (via sciencedaily.com)     Original source 

Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent study shows that the interactions between plants and pollinators, which are important for agricultural production, are surprisingly dynamic. For example, the plant and bee species involved in pollination vary greatly between the seasons.

It turns out, this fossil 'plant' is really a fossil baby turtle      (via sciencedaily.com)     Original source 

Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.

Money to burn: Wealthy, white neighborhoods losing their heat shields      (via sciencedaily.com)     Original source 

White, wealthy neighborhoods in the LA area -- and likely around the world -- are about to start feeling the same heat that has plagued poorer, Hispanic neighborhoods for generations. A new study shows the protective effect of income has largely eroded over the past 40 years, as landscape plants can't keep up with the pace of climate warming.
