Our new world order is particularly brutal for trees. Between climate change and economic greed, these lifegiving – and lifesaving – plants are not doing so well.
Besides well-known, large-scale devastations such as wildfires and deforestation (particularly of the Amazon, whose mighty forests are the reason the region is called – for now, anyway – the lungs of the planet), incremental changes are wreaking quieter, though no less devastating, impacts; for example, species native to the American South can no longer survive the warmer climate and so are spreading into cooler Northern climes. Behind them comes desertification.

California's giant Sequoias can live for more than 3,000 years, their trunks stretching two car lengths in diameter, their branches reaching nearly 300 feet toward the clouds. But a few years ago, amid a record drought, scientists noticed something odd. A few of these arboreal behemoths inside Sequoia and Kings Canyon National Parks were dying in ways no one had ever documented—from the top down.
When researchers climbed into the canopies, they discovered that cedar bark beetles had bored into a few branches. By 2019, at least 38 of the trees had died—not a large number, but “concerning because we’ve never observed this before,” says Christy Brigham, the park’s chief of resource management.

Israeli researchers have discovered collaboration between trees deep in the ground, Weizmann Institute of Science (WIS) in central Israel said Wednesday.
In their study, WIS researchers found underground intricate networks of fungi connecting the roots of different tree species with one another.
These networks enable the trees to exchange of minerals, nutrients, water and carbon, while funneling carbon to the fungi in return.

The Israeli company Phytolon, which is known for developing a fermentation-based technology for the production of plant-based food colors, announced on Thursday that it has secured $4.1 million from various companies and investors.
Some of the companies and investors providing the funding include major companies such as Millennium Food-Tech, EIT Food, Consensus Business Group, The Trendlines Group and also the Israel Innovation Authority. Phytolon's innovative products utilizes scientific advancement in biotechnology to produce natural food colors that are more environmentally sustainable, driven by the fact that consumers are seeking healthier food colors to replace synthetic ones.

Dec 17, 2020... In this video discussion, renowned plant scientist Prof. Asaph Aharoni takes us on a tour of his lab before sitting down to talk about his research. He particularly focuses on using plants to improve health and tackle major problems such as hunger and malnutrition.
Mar 17, 2021... Food insecurity – lack of consistent access to sufficient, nutritious food – was a major public-health concern before the pandemic. Climate change’s extended droughts, destructive fires and storms, and rising waters are wiping out resources in many areas, notably India and Africa. Poverty is another contributing factor, particularly in cities with “food deserts” where it is hard to find fresh fruit and vegetables and other healthy options. (Interestingly, the World Bank reports that “children who are properly nourished during the first 1,000 days of their lives are 33% more likely to escape poverty as adults.”)

May 18, 2021... REHOVOT, ISRAEL—May 18, 2021—A natural food supplement reduces anxiety in mice, according to a new Weizmann Institute of Science study. The plant-derived substance, beta-sitosterol, was found to produce the calming effect both on its own and in synergic combination with a common antidepressant, fluoxetine (brand name Prozac). If these findings, published in Cell Reports Medicine, are confirmed in clinical trials, they could point the way toward the use of beta-sitosterol as a treatment for relieving anxiety in humans.

REHOVOT, ISRAEL—December 1, 2021—A brown blotch on a plant leaf may be a sign that the plant’s defenses are hard at work.
A new study at the Weizmann Institute of Science, published today in Nature, points to the evolutionary origins of this plant immune mechanism.
When a plant is infected by a virus, fungus or bacterium, its immune response arrests the spread of the disease by killing the infected cell and those immediately surrounding it. The new Weizmann study may help explain how major plant defenses work and how they may one day be strengthened to increase resilience against plant diseases that each year cause billions of dollars of crop losses worldwide.

Justine Karst, a mycologist at the University of Alberta, feared things had gone too far when her son got home from eighth grade and told her he had learned that trees could talk to each other through underground networks.
Her colleague, Jason Hoeksema of the University of Mississippi, had a similar feeling when watching an episode of “Ted Lasso” in which one soccer coach told another that trees in a forest cooperated rather than competed for resources.
Feb 03, 2023... REHOVOT, ISRAEL— February 3, 2023 Arthropods crawl and buzz around us in the wild and on farmlands, on the street and at home, under our floors and in our plumbing systems, even in our food and on our bodies. But while we often are inconvenienced by this group of invertebrates – which comprises more than a million species, including all insects – their absence would be catastrophic: Arthropods are ecosystem engineers that pollinate our crops, turn over agricultural soils and sustain an enormous diversity of predators, from warblers to wolverines, that feed on them directly or indirectly.
