An evolutionary battleground: Plants vs. microbes
Gazing out on a freshwater pond, you may see tiny green plants with oval-shaped leaves floating in clusters. In overgrown ponds, these plants coat the water's surface. These plants—called duckweed or water lentils—can grow so fast that they can d.....»»
Newly identified mysterious fossil seed reveals Ice Age climate patterns
La Brea Tar Pits scientists have identified a previously unknown juniper species as Juniperus scopulorum, commonly known as the Rocky Mountain Juniper. The successful identification, along with the first-ever radiocarbon dating of these fossil plants.....»»
Researchers unveil chip for quick antibiotic monitoring in water
Antimicrobial resistance (AMR) is a growing global health crisis because of microbes, such as bacteria, becoming resistant to antibiotics. A leading factor in this rise is the improper use and disposal of antibiotics in the environment......»»
Solving renewable energy’s sticky storage problem
When the Sun doesn't shine and the wind is calm, humankind still needs power. When the Sun is blazing and the wind is blowing, Germany’s solar and wind power plants swing into h.....»»
Evolutionary study reveals toxic reach of disease-causing bacteria across plant kingdom
The capacity of bacteria to spread disease across the plant kingdom may be much more widespread than previously suspected, according to new analysis......»»
Top 10 plant and fungal species named new to science in 2024
Scientists from the Royal Botanic Gardens, Kew and their partners reveal their pick of the top 10 plants and fungi named new to science in 2024......»»
Researchers address material challenges to make commercial fusion power a reality
Imagine if we could take the energy of the sun, put it in a container, and use it to provide green, sustainable power for the world. Creating commercial fusion power plants would essentially make this idea a reality. However, there are several scient.....»»
Scientists provide insights into photosystem II under low-light conditions
In higher plants and green algae, photosystem II (PSII) usually combines with light harvesting complex II (LHCII) to form the PSII-LHCII supercomplex. Under low-light conditions, the PSII-LHCII supercomplexes are organized laterally into higher-order.....»»
How a giant prehistoric elephant skull helped untangle an evolutionary mystery
About 400,000 years ago, early humans in Europe, Asia and Africa lived alongside giant straight-tusked elephants, far bigger than their modern-day cousins. Their evolution has long been a mystery to paleontologists, but an extraordinary, enormous and.....»»
Ocean microbe"s unusual pair of enzymes may boost carbon storage
Stanford researchers have found a surprising genetic twist in a lineage of microbes that may play an important role in ocean carbon storage. The microbes, known as blue-green algae or cyanobacteria, have two different forms of a ubiquitous enzyme tha.....»»
A history of bacteria domestication: Researchers investigate genetic and phenotypic characteristics of Swiss cheeses
The domestication of livestock and plants marked an important stage in the settlement of human populations in the Neolithic period, as they moved from a hunter-gatherer lifestyle to a subsistence model based on animal husbandry and agriculture. Becau.....»»
Twins were the norm for our ancient primate ancestors—one baby at a time had evolutionary advantages
Twins have been rare in human history and for that reason can seem special. Many cultures associate twins with health and vitality, while others see them as a philosophical reminder of the duality of life and death, good and evil. Some famous twins a.....»»
Completing the "timetree" of primates: A new way to map the evolutionary history of life on Earth
In a new article published in Frontiers in Bioinformatics, biologists Dr. Jack M Craig, Dr. Blair Hedges, and Dr. Sudhir Kumar, all at Temple University, have built an evolutionary tree that encompasses 455 primates, every species for which genetic d.....»»
Genetic method leverages bacterial transfer mechanism to produce new active ingredients
Microorganisms produce a wide variety of natural products that can be used as active ingredients to treat diseases such as infections or cancer. The blueprints for these molecules can be found in the microbes' genes, but often remain inactive under l.....»»
Infrared quantum ghost imaging illuminates—but doesn"t disturb—living plants
A study published in the journal Optica demonstrates live plant imaging of several representative plant samples, including the biofuel crop sorghum. By employing a novel detector, researchers obtained clear images of living sorghum plants with a ligh.....»»
Uncovering the evolutionary origins of the hepatitis E virus
An international team of virologists, mammalian ecologists and zoologists has uncovered the evolutionary origins of the hepatitis E virus. In their study, published in the Proceedings of the National Academy of Sciences, the group analyzed genomic da.....»»
Enzymes evolved mix-and-match characteristics to shape nitrogen metabolism diversity across the planet
To boost crops more efficiently in the future, the evolutionary past may hold key insights. The way that plants process nutrients has a rich back story—they rely on enzymes that have been evolving for billions of years. However, these enzymes are o.....»»
Two key proteins boost tomato"s phosphorus efficiency and plant health
Phosphorus is a critical nutrient for plant growth, yet it is often locked away in soils and inaccessible to plants. The natural process of arbuscular mycorrhizal symbiosis (AMS), in which plants exchange carbon for essential nutrients with fungi, is.....»»
Centromeres could be "hotspots" for evolutionary innovation
New research reveals that centromeres, which are responsible for proper cell division, can rapidly reorganize over short time scales. Biologists at the University of Rochester are calling a discovery they made in a mysterious region of the chromosome.....»»
AI"s power demands driving toxic air pollution, study finds
Computer processing demands for artificial intelligence, or AI, are spurring increasing levels of deadly air pollution from power plants and backup diesel generators that continuously supply electricity to the fast-growing number of computer processi.....»»
A microRNA solves an evolutionary mystery of butterfly and moth wing coloration
Lepidopterans (butterflies and moths) exhibit a splendid diversity of wing color patterns, and many species display black and white, or dark and bright, wing color pattern variants associated with the presence and absence of melanin. Many of these wi.....»»
