Published Miocene period fossil forest of Wataria found in Japan
(via sciencedaily.com) Original source An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.
Published Gene variation makes apple trees 'weep,' improving orchards
(via sciencedaily.com) Original source Plant geneticists have identified a mutation in a gene that causes the 'weeping' architecture -- branches growing downwards -- in apple trees, a finding that could improve orchard fruit production.
Published Building a better forest tree with CRISPR gene editing
(via sciencedaily.com) Original source Researchers use CRISPR techniques to modify lignin levels in poplar trees.
Published Forest can adapt to climate change, but not quickly enough
(via sciencedaily.com) Original source America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.
Published Study reveals how a tall spruce develops defense against hungry weevils
(via sciencedaily.com) Original source A study has identified genes involved in development of stone cells -- rigid cells that can block a nibbling insect from eating budding branches of the Sitka spruce evergreen tree. The insect's attack has stunted the growth of these forest giants.
Published Board games are boosting math ability in young children
(via sciencedaily.com) Board games based on numbers, like Monopoly, Othello and Chutes and Ladders, make young children better at math, according to a comprehensive review of research published on the topic over the last 23 years.
Published Biotechnology offers holistic approach to restoration of at-risk forest tree species
(via sciencedaily.com) Original source Many at-risk forest tree species will probably need biotechnology along with traditional tree-breeding approaches to survive, according to new insights.
Published A seed survival story: How trees keep 'friends' close and 'enemies' guessing
(via sciencedaily.com) Original source A new study that included millions of tree-year observations worldwide for the first time documents and analyzes the intricate balance between seed defense and dispersal by forest trees at a global scale.
Published How the brain processes numbers -- New procedure improves measurement of human brain activity
(via sciencedaily.com) Original source Measuring human brain activity down to the cellular level: until now, this has been possible only to a limited extent. With a new approach it will now be much easier. The method relies on microelectrodes along with the support of brain tumor patients, who participate in studies while undergoing 'awake' brain surgery. This enabled the team to identify how our brain processes numbers.
Published Mathematicians solve long-known problem
(via sciencedaily.com) Original source Making history with 42 digits: Scientists have unlocked a decades-old mystery of mathematics with the so-called ninth Dedekind number. Experts worldwide have been searching for the value since 1991. Scientists arrived at the exact sequence of numbers with the help of the Noctua supercomputer.
Published 'Shoebox' satellites help scientists understand trees and global warming
(via sciencedaily.com) Original source As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.
Published Older trees accumulate more mutations than their younger counterparts
(via sciencedaily.com) Original source A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.
Published The other side of the story: How evolution impacts the environment
(via sciencedaily.com) Original source Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.
Published Study leads to milestone advances in understanding lethal bronzing of palm trees
(via sciencedaily.com) Original source Scientists have identified a key chemical associated with lethal bronzing (LB) infected palm trees. LB is a bacterial disease that kills more than 20 species of palm trees in the Southern United States and Caribbean and has been devastating the Florida green industries for nearly two decades.
Published How a drought affects trees depends on what's been holding them back
(via sciencedaily.com) Original source Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Published Preserving pine forests by understanding beetle flight
(via sciencedaily.com) Original source Researchers study the flight performance of the mountain pine beetle from a fluid mechanics and an entomological perspective. Understanding these aspects of the insect's flight could improve estimates of its spread through the environment and preserve pine forests. To examine insect flight, the team employed a type of model previously used for idealized airfoils. They showed that it can be successfully applied to multiple individual animals across biological sex, insect age, and body size. In doing so, the model can predict how these factors impact flight characteristics.
Published Beetles and their biodiversity in dead wood
(via sciencedaily.com) Original source Which energy type promotes the biodiversity of beetles living in dead wood in the forest? That depends entirely on where the beetles are in the food chain.
Published Exploring the underground connections between trees
(via sciencedaily.com) Original source Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.
Published QuanÂtum comÂputer in reverse gear
(via sciencedaily.com) Original source Large numbers can only be factorized with a great deal of computational effort. Physicists are now providing a blueprint for a new type of quantum computer to solve the factorization problem, which is a cornerstone of modern cryptography.
Published Researchers explore why some people get motion sick playing VR games while others don't
(via sciencedaily.com) Original source The way our senses adjust while playing high-intensity virtual reality games plays a critical role in understanding why some people experience severe cybersickness and others don't.
