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.

Plant nurseries are exacerbating the climate-driven spread of 80% of invasive species      (via sciencedaily.com)     Original source 

Researchers have provided detailed maps of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.

Sugar permeation discovered in plant aquaporins      (via sciencedaily.com)     Original source 

Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.

Mathematics supporting fresh theoretical approach in oncology      (via sciencedaily.com)     Original source 

Mathematics, histopathology and genomics converge to confirm that the most aggressive clear cell renal cell carcinomas display low levels of intratumour heterogeneity, i.e. they contain fewer distinct cell types. The study supports the hypothesis that it would be advisable to apply therapeutic strategies to maintain high levels of cellular heterogeneity within the tumour in order to slow down the evolution of the cancer and improve human survival.

Decoding flavonoid metabolism: A closer look at plant-based diets      (via sciencedaily.com)     Original source 

An international team of researchers has elucidated the process by which the major flavonoids naringenin, apigenin, and genistein are metabolized in the body. These findings are fundamental in elucidating the correlation between the metabolism of flavonoids in the body and their potential health benefits.

Scientists use A.I.-generated images to map visual functions in the brain      (via sciencedaily.com)     Original source 

Researchers have demonstrated the use of AI-selected natural images and AI-generated synthetic images as neuroscientific tools for probing the visual processing areas of the brain. The goal is to apply a data-driven approach to understand how vision is organized while potentially removing biases that may arise when looking at responses to a more limited set of researcher-selected images.

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.

how far can the wind can carry a plant's seeds? New model      (via sciencedaily.com)     Original source 

Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.

Researchers decipher enzyme scissors of intestinal microbes      (via sciencedaily.com)     Original source 

Fruit and vegetables contain a variety of plant natural products such as flavonoids, which give fruits their colour and are said to have health-promoting properties. Most plant natural products occur in nature as glycosides, i.e. chemical compounds with sugars. In order for humans to absorb the healthy plant natural products, the sugar must be split off in the intestine. Microorganisms in the intestinal flora help to speed up the process. So-called C-glycosides, i.e. plant natural products with a carbon-based bond to a sugar, would even be practically indigestible without the intestinal microbes (e.g. nothofagin in rooibos tea).

Flower power on Indian farms helps bees and boosts livelihoods      (via sciencedaily.com)     Original source 

Planting flowers beside food crops on farms in India attracts bees, boosts pollination and improves crop yield and quality, researchers have found.

A spectrum of possibilities: Insights into the evolution of far-red light photosynthesis      (via sciencedaily.com)     Original source 

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could pave the way for engineering plants with enhanced light absorption capabilities and has implications for our search for extraterrestrial life.

Slash-and-burn agriculture can increase forest biodiversity, researchers find      (via sciencedaily.com)     Original source 

The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.

The Fens of eastern England once held vast woodlands      (via sciencedaily.com)     Original source 

The Fens of eastern England, a low-lying, extremely flat landscape dominated by agricultural fields, was once a vast woodland filled with huge yew trees, according to new research. Scientists have studied hundreds of tree trunks, dug up by Fenland farmers while ploughing their fields. The team found that most of the ancient wood came from yew trees that populated the area between four and five thousand years ago.

Researchers puncture 100-year-old theory of odd little 'water balloons'      (via sciencedaily.com)     Original source 

Quinoa and many other extremely resilient plants are covered with strange balloon-like 'bladders' that for 127 years were believed to be responsible for protecting them from drought and salt. Research results reveal this not to be the case. These so-called bladder cells serve a completely different though important function. The finding makes it likely that even more resilient quinoa plants will now be able to be bred, which could lead to the much wider cultivation of this sustainable crop worldwide.
