How plants produce defensive toxins without harming themselves
Plants produce toxic substances to defend themselves against herbivores. In a new study, scientists from the Max Planck Institute for Chemical Ecology in Jena and the University of Münster, Germany, were able to describe in detail the biosynthesis a.....»»
Climate change is wiping out rare bacteria in a "greening" Antarctica
Plenty is known about the existential threat of climate change to plants and animals. But by comparison, we know very little about how microorganisms will be affected by climate change......»»
How a cyanobacterium manages iron scarcity makes it the most successful photosynthetic organism on Earth
The sea is the world's largest ecosystem, and it harbors two photosynthetic organisms that produce approximately half of the oxygen on Earth. The cyanobacterium Prochlorococcus is the most abundant photosynthetic organism in the oceans and fixes appr.....»»
NASA observations find what helps heat roots of "moss" on sun
Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mi.....»»
Silver-based micromotors that eliminate bacteria can move freely in aqueous media
Researchers at ICIQ in Tarragona have developed a simple technique to produce microscopic crystals that activate in the presence of light, releasing silver ions with antimicrobial activity......»»
CO₂ worsens wildfires by helping plants grow, model experiments show
By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a UC Riverside study......»»
Pioneering crop productivity and sustainability in the face of water scarcity
A research team has shed light on the early morning "golden hours" as a pivotal time for achieving optimal water use efficiency (WUE) in crops, revealing that plants can maintain lower transpiration rates and higher photosynthetic activity under favo.....»»
Honda"s first in-house EV starts production in 2025
Honda is retooling three existing plants in Ohio to produce EVs and EV components and is building a joint-venture battery factory with LG Energy Solution......»»
Attosecond imaging made possible by short and powerful laser pulses
Extremely short pulses of laser light with a peak power of 6 terawatts (6 trillion watts)—roughly equivalent to the power produced by 6,000 nuclear power plants—have been realized by two RIKEN physicists. This achievement will help further develo.....»»
Twisted pollen tubes induce infertility in plants with multiple sets of chromosomes
Most mammals and humans have a double set of chromosomes—and as a rule, plants do, too: One set comes from the father, the other from the mother. Such organisms are called diploids. However, sometimes the number of chromosome sets doubles from one.....»»
Seed ferns experimented with complex leaf vein networks 201 million years ago, paleontologists find
According to a research team led by paleontologists from the University of Vienna, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times. Using new methods, the.....»»
New catalyst allows energy-friendly ammonia production for fertilizers and alternative fuel
Researchers led by Satoshi Kamiguchi at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have discovered a greener way to produce ammonia, an essential compound used in fertilizers......»»
Boron deficiency in oilseed rape transcriptome resembles a wounding and infection response
Boron deficiency has a devastating effect on oilseed rape and related plants. However, little is known about the underlying genetic mechanisms. A study shows that the response to persistent or short-term acute boron deficiency is similar to that seen.....»»
Stellantis clashes with suppliers spill into court, shut down plants
The maker of the Jeep, Chrysler, Dodge and Ram brands has taken a hard line toward parts makers seeking inflationary cost relief, rolling out a “no more claims” policy earlier this year......»»
Researchers discover previously unknown gene that indirectly promotes photosynthesis in blue-green algae
Cyanobacteria—also called blue-green algae—are known as the "plants of the ocean" because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need add.....»»
Newly sequenced genome reveals coffee"s prehistoric origin story, and its future under climate change
The key to growing coffee plants that can better resist climate change in the decades to come may lie in the ancient past......»»
Stellantis clashes with suppliers, spilling into court and shutting down plants

Yellow-eyed grasses may have more insect visitors than previously thought
Scientists previously believed that a family of flowering plants called yellow-eyed grasses didn't attract many insect visitors, but the recent discovery of a fungus that hijacks the plant and forms fungal "pseudoflowers" has researchers rethinking t.....»»
Scientists discover first nitrogen-fixing organelle
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recen.....»»
Study proposes large-scale biomanufacturing workflow to produce natural killer cells and extracellular vesicles
A team of uOttawa Faculty of Medicine researchers have developed a path to a biomanufacturing process that could potentially transform how Canada generates immunotherapeutic materials—specifically natural killer cells and extracellular vesicles (EV.....»»
GM plans downtime for retooling at Fort Wayne pickup plant
Four components plants in Michigan, Indiana and Ohio also will be idled connected to the downtime at Fort Wayne Assembly, GM said......»»
