Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Researchers reveal a hidden trait in Mycobacterium genomes governing stress adaptation
A new study, led by Qingyun Liu, Ph.D., assistant professor in the Department of Genetics, has uncovered a genetic feature known as "transcriptional plasticity," which plays a pivotal role in governing the transcriptional response of Mycobacteria to.....»»
Mobile genetic elements can inadvertently suppress bacterial immune systems, research reveals
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions.....»»
Researchers identify genetic variant that helped shape human skull base evolution
Humans, Homo sapiens, have unique features compared with other closely related hominin species and primates, including the shape of the base of the skull. The evolutionary changes underlying these features were significant in allowing the evolution o.....»»
Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation
A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previo.....»»
Researchers propose new formation model for massive hot subdwarfs
In a new study published in the The Astrophysical Journal, Dr. Li Zhenwei and his collaborators from Yunnan Observatories of the Chinese Academy of Sciences (CAS), and Dr. Zhang Yangyang from the Zhoukou Normal University, proposed a new formation mo.....»»
Scientists explore the genetic foundations of Rhododendron flower color diversity
A research team has made strides in uncovering the genetic foundations of flower color variation within the Rhododendron genus. The team's review summarizes recent advancements in phylogenetic reconstruction, genome sequencing of various Rhododendron.....»»
Researchers find cryptic genetic element in the human gut that could serve as a sensitive biomarker
A component of the human intestinal flora that has been little studied to date is the focus of a new study from Germany. Plasmids are small extrachromosomal genetic elements that frequently occur in bacterial cells and can influence microbial lifesty.....»»
New time-resolved ultraviolet photodissociation mass spectrometry strategy for target protein stability analysis
How mutations impact protein stability and structure dynamics is crucial for understanding the molecular mechanism of the disease and the targeted drug design. However, probing the molecular details of mutation-induced subtle structure dynamics is st.....»»

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.....»»
Formation-flying spacecraft could probe the solar system for new physics
It's an exciting time for the fields of astronomy, astrophysics, and cosmology. Thanks to cutting-edge observatories, instruments, and new techniques, scientists are getting closer to experimentally verifying theories that remain largely untested. Th.....»»
First insights into the genetic bottleneck characterizing early sheep husbandry in the Neolithic period
Modern Eurasian sheep predominantly belong to only two so-called genetic matrilineages inherited through the ewes, so previous research has assumed that genetic diversity must already have decreased rapidly in the early stages of domestication of wil.....»»
Tracing the lineage of North America"s native Blackfoot Confederacy
A team of researchers with varied backgrounds and affiliated with multiple organizations (including the Blackfoot Confederacy) in the U.S. and Canada has conducted a genetic study focused on tracing the lineage of North America's native Blackfoot Con.....»»
Giant rogue waves: Southern Ocean expedition reveals wind as key cause
A University of Melbourne expedition to the southernmost waters encircling Antarctica has discovered that wind drives the formation of colossal rogue waves, and that these unpredictable waves occur more frequently than scientists had previously thoug.....»»
"Bluey" special episode "The Sign" had a ton of Easter eggs for fans
"Bluey" special episode "The Sign" is full of Easter eggs and nods to past episodes, including updates on Winton's dad and Auntie Brandy. Bluey aired its longest episode ever on the weekend, the beloved Australian cartoon delivering 28-minutes.....»»
Macroalgae genetics study sheds light on how seaweed became multicellular
A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or "seaweed," to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time perio.....»»
Iconic savanna mammals face genetic problems due to fences and roads
Whether by way of Attenborough, Disney or National Geographic, the iconic scene is familiar to many. The ground trembles and clouds of dust swirl as enormous hordes of large animals thunder across the African savanna, cross rivers en masse and are pi.....»»
Traces of DNA in the stomachs of predatory snails provide new insights into the ecology of placozoans
Placozoans are among the simplest animals and occur worldwide in coastal waters. It was previously assumed that the tiny creatures, which measure just a few millimeters, live either on hard surfaces—such as rocks, corals, and mangrove roots—or fl.....»»
New study finds potential targets at chromosome ends for degenerative disease prevention
We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied in a complete way during c.....»»
