Discovery of bacterial proteins that induce asexual reproduction in insects
From microbes in the human gut to symbiotic algae in coral reefs, research in recent decades has increasingly revealed the pivotal roles that microorganisms (or microbial species) play in shaping the biology of host organisms and of broader ecosystem.....»»
Cartilage healing discovery in animal models could lead to new human therapies
Researchers hope their discovery about the healing properties of fetal cartilage cells in mice will lay the groundwork for new treatments for human growth disorders and degenerative diseases......»»
Study sheds light on the diversity of carnivore skull shapes and their function
In a study published in Nature Communications, a team of international researchers led by Gabriele Sansalone and Carmelo Fruciano has made a significant discovery about the diversity of skull shapes in carnivores......»»
Global study shows a third more insects come out after dark
A groundbreaking study, led by Dr. Mark Wong of The University of Western Australia, has provided the first global picture of insect activity patterns across the fundamental day–night cycle......»»
Florida dolphin found with highly pathogenic avian flu: Report
The case of a Florida bottlenose dolphin found with highly pathogenic avian influenza virus, or HPAIV—a discovery made by University of Florida researchers in collaboration with multiple other agencies and one of the first reports of a constantly g.....»»
Did Vesuvius bury the home of the first Roman emperor?
A group of archaeologists, led by researchers from the University of Tokyo, announce the discovery of a part of a Roman villa built before the middle of the first century. This villa, near the town of Nola in southwestern Italy's Campania region, was.....»»
Study details a common bacterial defense against viral infection
One of the many secrets to bacteria's success is their ability to defend themselves from viruses, called phages, that infect bacteria and use their cellular machinery to make copies of themselves......»»
Researchers decipher how an enzyme modifies the genetic material in the cell nucleus
Inside the cell nucleus, the DNA molecule is found in a densely packed DNA-protein complex known as chromatin. Here the DNA is wrapped around a core of histone proteins and densely packed to form nucleosomes. The structure of the nucleosomes determin.....»»
Genetic hope in fight against devastating wheat disease
Fungal disease Fusarium head blight (FHB) is on the rise due to increasingly humid conditions induced by climate change during the wheat growing season, but a fundamental discovery by University of Adelaide researchers could help reduce its economic.....»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
A systematic review of three key sugar metabolism proteins: HXK, SnRK1 and TOR
Sugar signaling is one of the most important regulatory signals for plant growth and development, and its metabolic network contains many regulatory factors. Sugar signaling molecules regulate cellular activities and organismal development by interac.....»»
TESS finds its first rogue planet
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising discovery; their first free.....»»
A shortcut for drug discovery: Novel method predicts on a large scale how small molecules interact with proteins
For most human proteins, there are no small molecules known to bind them chemically (so-called "ligands"). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel.....»»
Scientists confine, study Chinook at restored Snoqualmie River habitat
In newly restored river channels on the Snoqualmie, baby Chinook salmon are confined in 19 enclosures about the size of large suitcases as they munch on little crustaceans and invertebrate insects floating or swimming by......»»
Illinois residents encouraged to destroy the eggs of invasive insects to slow spread
While Chicagoans were alarmed to learn the spotted lanternfly had been found in Illinois last year, experts say spring is the time to take action against that insect—as well as another damaging invasive species that has made far more inroads and go.....»»
Researchers create artificial cells that act like living cells
In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins—essential building blocks of life—to create cells that look and act like cells f.....»»
Supercomputer simulation reveals new mechanism for membrane fusion
An intricate simulation performed by UT Southwestern Medical Center researchers using one of the world's most powerful supercomputers sheds new light on how proteins called SNAREs cause biological membranes to fuse......»»
Researchers report on mechanisms of gene regulatory divergence between species
Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins' structure or function, but also because changes in the DNA aff.....»»
First discovery in decades of blue whales near Seychelles
Blue whales are fascinating animals. At 24–30 meters in length (longer than a basketball court) they are the largest creatures on Earth. They are also among the rarest. Estimates suggest that there are only about 5,000 to 15,000 blue whales left in.....»»
Researchers map protein network dynamics during cell division
An international team led by researchers at the University of Toronto has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the.....»»
Astronomers offer new model for formation of recently discovered "free-floating" planets
The recent discovery of a potential new class of distant and mysterious "free-floating" planets has intrigued astronomers since stunning new images captured by the James Webb Space Telescope were shared late last year......»»
