For several years, ecological research has argued that climate often has no determining influence on the distribution of forests and savannas in tropical regions. However, an international research team led by Prof. Dr. Steven Higgins at the University of Bayreuth has now succeeded in proving that it depends mostly on climatic factors whether regions in Africa are covered by forest or savanna. The study, published in "Science", thus confirms the dominant role of climate in the formation of global vegetation patterns.

In a study published in Nature Communications, scientists assess a new technique which could convert renewable, green energy from outside the Earth’s atmosphere. They are taking advantage of photosynthesis – the chemical process plants undergo every day to create energy – to help the space industry become more sustainable.

Scientists at Brookhaven Lab have determined the atomic-level structure of a zinc-transporter protein, a molecular machine that regulates levels of this crucial trace metal micronutrient inside cells. The structure reveals how the cellular membrane protein shifts its shape to move zinc from the environment into a cell, and temporarily blocks this action automatically when zinc levels inside the cell get too high.

Scientists showed that chemical compounds of perennial plant meadowsweet are distributed unevenly. They found out that in new leaves chemically active compounds are stored, and in the old ones – predecessors of polymers that don’t take part in any chemical reactions.

Especially after the last few COVID-affected years, nobody doubts that emerging infectious diseases can threaten the whole world. But humans are not the only ones at risk! With intensive global trade, many tree parasites are accidently introduced to Europe in packaging or directly on goods. Traveling in the wood, on plants or in the soil of their pots, they can remain undetected for a long time.

Defense of the United States is an undertaking that requires the help of experts from a wide array of obviously related disciplines — physics, engineering, computer science, political science and more. One discipline that might not immediately come to mind is plant ecophysiology. But the University of Nebraska–Lincoln’s Tala Awada is leading the way.

Nature-based solutions are an effective tool to combat climate change triggered by rising carbon emissions, whether it’s by clearing the skies with bio-based aviation fuels or boosting natural carbon sinks. At the Department of Energy’s Oak Ridge National Laboratory, scientists are leading research to transform plants into key drivers of decarbonization, from creating biomass crops for new fuels to enhancing the ability of plants to absorb and store carbon.

Plants live across wide ranges of heat and cold and rain and drought, but they don’t fill their niches alone. Along with the animals and insects that live on and around a tree — pitching in now and then to aid pollination or pest control or seed dispersal — there are innumerable microbes in the soil (like various fungi that grow alongside tree roots). These microbes can blunt the normal stresses of life by helping trees draw in more nutrients and water or influencing the time they leaf out or flower to best match seasonal conditions.

A movement is raising awareness of native gromwell plant's importance in preserving Japanese culture. For example, revival projects currently underway throughout Japan are investigating the seed's origins and educating the public on the importance of protecting the plant's homogeneity. Purple gromwell contains shikonin derivatives in the plant's root surfaces, which are red naphthoquinones. This natural pigment and medicinal properties are linked to ancient East Asian traditions.

Eight years ago, University of Illinois and USDA-ARS scientists turned weed control on its head. More and more herbicide resistant weeds were popping up, and the pest plants were getting harder to kill. It was clear farmers could no longer rely on the same chemicals year after year. Industry campaigns and herbicide applicators began touting the benefits of rotating herbicides annually to avoid developing resistance, and rotation quickly became common practice.

Walking along a steep ridge, under large hemlock trees, ten miles outside of Burlington, Vermont—Bill Keeton is worrying about Europe’s remaining old forests. He’s so concerned, in fact, that he and some colleagues wrote a letter to the journal Science—published on May 5, 2023—calling for rapid action to protect them.

Let’s say you’re a corn grower farming on low-fertility soil. How do you go about making that soil healthier and more fertile? Many farmers think if they add plenty of nitrogen fertilizer, that nutrient, along with carbon, will be stored in the soil as organic matter when microbes decompose crop residue. But new research from the University of Illinois suggests those efforts might not work for poor soils.

Spread across 106 acres in southcentral Utah, the Pando aspen grove resembles a forest but is actually a single organism with more than 47,000 genetically identical aspen stems connected at the root. As an artist-in-residence for the nonprofit group Friends of Pando, Jeff Rice used a variety of microphones to record Pando’s leaves, birds, and weather. As part of the 184th ASA Meeting, Rice and Lance Oditt will describe their work to reveal a unique acoustic portrait of this botanical wonder.

Photosynthesis plays a crucial role in shaping and sustaining life on Earth, yet many aspects of the process remain a mystery. One such mystery is how Photosystem II, a protein complex in plants, algae and cyanobacteria, harvests energy from sunlight and uses it to split water, producing the oxygen we breathe. Now researchers from the Department of Energy’s Lawrence Berkeley National Laboratory and SLAC National Accelerator Laboratory, together with collaborators from Uppsala University and Humboldt University and other institutions have succeeded in cracking a key secret of Photosystem II.

Cycads, a group of gymnosperms which can resemble miniature palm trees (like the popular sago palm houseplant) were long thought to be “living fossils,” a group that had evolved minimally since the time of the dinosaurs. Now, a well-preserved 80-million-year-old pollen cone discovered in California has rewritten scientific understanding of the plants.

In just six years since the 39 North Master Plan was unveiled, more than $120 million of private/public investment has been made to advance the goals outlined in the plan. To build on the momentum, seven institutions from the public/private sector have announced their commitment as anchor institutions and established 39 North AgTech Innovation District as a 501(c)3. The new organization will be responsible for elevating the innovation district to the next level of successful growth and economic impact.
