Palms at the poles: Fossil plants reveal lush southern hemisphere forests in ancient hothouse climate

Plant fossils dating back 55 to 40 million years ago, during the Eocene epoch reveal details about the warmer and wetter climate. These conditions meant there were palms at the North and South Pole and predominantly arid landmasses like Australia were lush and green. By focusing on the morphology and taxonomic features of 12 different floras, the researchers developed a more detailed view of what the climate and productivity was like in the ancient hothouse world of the Eocene epoch. from Top Environment News -- ScienceDaily https://ift.tt/CHhsobY

Fjords emit as much methane as all the deep oceans globally

During heavy storms, the normally stratified layers of water in ocean fjords get mixed, which leads to oxygenation of the fjord floor. But these storm events also result in a spike in methane emissions from fjords to the atmosphere. Researchers have estimated that the total emissions of this climate-warming gas are as great from fjords as from all the deep ocean areas in the world put together. from Top Environment News -- ScienceDaily https://ift.tt/GI5dDrB

Professional 'guilds' of bacteria gave rise to the modern microbiome

Even the smallest marine invertebrates -- some barely larger than single-celled protists -- are home to distinct and diverse microbial communities, or microbiomes, according to biologists. The study underscores that a vast diversity of animals have microbiomes, just as humans do. But more surprisingly, there's little correlation between how closely related most animals are and how similar their microbiomes are -- something widely assumed to be true based on the study of humans, larger mammals, and insects. from Top Environment News -- ScienceDaily https://ift.tt/X9cVEv1

New research on tidal flats is 'wake up call' for US coastal communities

About 41 million people in live in U.S. Atlantic coastline counties. There isn't an effective way to identify the impact of urban growth on tidal flats -- the guardians of beachfront communities. Researchers have developed a new way to quantify these impacts from a geographic lens focused on place and space using data over three decades. Analyzing the annual dynamics of three highly urbanized coastal counties in the southeastern U.S., results show that tidal flats in these three counties urgently need a sustainable plan of management in response to the rapid expansion of urban areas. Importantly, their new technique can be revised and applied to the entire U.S. as research now is limited to individual cities. from Top Environment News -- ScienceDaily https://ift.tt/ZISMKOU

What happens when plants have stress reactions to touch

A 30-year-old genetic mystery has been solved. It has previously been established that touch can trigger stress reactions in plants.

Light pollution can disorient monarch butterflies

Biologists say nighttime light pollution can interfere with the remarkable navigational abilities of monarchs, which travel as far as Canada to Mexico and back during their multi-generational migration. Researchers found that butterflies roosting at night near artificial illumination such as a porch or streetlight can become disoriented the next day because the light interferes with their circadian rhythms. Artificial light can impede the molecular processes responsible for the butterfly's remarkable navigational ability and trigger the butterfly to take wing when it should be resting. from Top Environment News -- ScienceDaily https://ift.tt/MAofeC9

Diets high in fiber associated with less antibiotic resistance in gut bacteria

Healthy adults who eat a diverse diet with at least 8-10 grams of soluble fiber a day have fewer antibiotic-resistant microbes in their guts, according to a new study.

New method to synchronize devices on Earth makes use of cosmic rays

Various technologies, networks and institutions benefit from or require accurate time keeping to synchronize their activities. Current ways of synchronizing time have some drawbacks that a new proposed method seeks to address. The cosmic time synchronizer works by synchronizing devices around cosmic ray events detected by those devices. This could bring accurate timing abilities to remote sensing stations, or even underwater, places that other methods cannot serve. Early tests show promise, but the real challenge may lie in the adoption of this new technique. from Top Environment News -- ScienceDaily https://ift.tt/hPlDr8G

Failed eruptions are at the origin of copper deposits

Copper is one of the most widely used metals on the planet today due to its electrical and thermal conduction properties. The greatest natural resources of this metal are the so-called 'porphyry' deposits that come from magmas deep in the Earth. In recent research, scientists demonstrate that these deposits are largely produced by mechanisms similar to those causing large volcanic eruptions. At a time when current copper resources are dwindling and this metal plays a key role in the energy transition, this discovery opens up new avenues for the development of tools to find new deposits. from Top Environment News -- ScienceDaily https://ift.tt/BaECdRF

Getting sticky with it: Phospholipid found to play a key role in epithelial cell adhesion

Cells have certain proteins that help them adhere to each other while covering body surfaces and organs. Loss of these identifying proteins could result in cellular progression towards cancer and, subsequently, metastasis. However, lipids may play a role in maintaining cellular identity as well. Scientists have now identified the role of PIP2, a phospholipid, in maintaining epithelial cell-cell adhesion and cellular identity.

Food insecurity risk related to diabetes later in life

Young adults who were at risk of food insecurity had increased incidence of diabetes 10 years later, according to a new study. While previous research has associated food insecurity with a range of health issues including diabetes, obesity and hypertension, this study showed a connection over time, suggesting a causal relationship. Researchers analyzed data on nearly 4,000 people from the National Longitudinal Study of Adolescent to Adult Health. They found that adults ages 24-32 who said they'd been worried about food running out in the last year showed greater incidence of diabetes, either through blood glucose tests or self-reports, at ages 32-42, compared to those who did not report food insecurity risk. from Top Environment News -- ScienceDaily https://ift.tt/7NbcIY9

Small changes -- but essential! How peptides are recognized in receptors

The human body consists of trillions of cells that constantly communicate with each other. A central role in this communication process is played by receptor proteins on the cell surface. Since they often serve as drug targets, they have been the subject of intensive research. Often there are whole families of receptors. The signal messengers as well as the receptors are very similar to each other, so it is not clear how the signals are distinguished from each other at the molecular level. Now, scientists have succeeded in determining high-resolution structures for three related signalling complexes that occur naturally in the body for the neuropeptide Y (NPY) receptor family, thus shedding light on the 'small but essential differences'. from Top Environment News -- ScienceDaily https://ift.tt/P5mREXr

Sweet spots in the sea: Mountains of sugar under seagrass meadows

Seagrasses play an important role in our climate. They are one of the most efficient sinks of carbon dioxide on Earth. A team of scientists now reports that seagrasses release large amounts of sugar, largely in the form of sucrose, into their soils -- worldwide more than 1 million tons of sucrose, enough for 32 billion cans of coke. Such high concentrations of sugar are surprising. Normally, microorganisms quickly consume any free sugars in their environment. The scientists found that seagrasses excrete phenolic compounds, and these deter most microorganisms from degrading the sucrose. This ensures that the sucrose remains buried underneath the meadows and cannot be converted into CO2 and returned to the ocean and atmosphere. from Top Environment News -- ScienceDaily https://ift.tt/MvwcQ61
