Research finds yellow warblers near busy roads turn aggressive when traffic drowns out their territorial songs, and noise pollution could cause clashesIf the rumble of trucks, honk of car horns and bustle of the roads leaves you irritable, you are not alone – researchers say the sound of traffic can leave birds in a rage, too.Researchers have found male Galápagos yellow warblers that live near busy roads on the islands behave more aggressively when they hear songs from another male if they occur in the presence of traffic sounds. Continue reading...

A new study has discovered that birds in the Galápagos Islands are changing their behavior due to traffic noise, with those frequently exposed to vehicles showing heightened levels of aggression.

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active regulator of gene expression at the level of protein biosynthesis. This is an important process for the development and function of cells, in which genetic information is converted into proteins. The final step, in which the information encoded on the messenger RNA (mRNA) is transferred, is known as translation.

A new study led by Dr. Hilla Chen from the Koret School of Veterinary Medicine at Hebrew University, recently published in the Journal of Veterinary Internal Medicine, offers new hope for the management of chronic kidney disease (CKD) in dogs. The research highlights the potential benefits of paricalcitol, a second-generation vitamin D analog, in addressing renal secondary hyperparathyroidism (RHPT) and proteinuria—two critical complications of CKD.

Almost everywhere in California, salmon are on the decline. But in Putah Creek—a restored stream running through the University of California, Davis, campus—wild salmon are not only increasing, they are also completing their life cycle.

Cornell University bee experts are analyzing samples of bees and related material to help identify the cause of unprecedented managed honey bee losses this winter.

Why do humans wear clothes? One reason is that changing outfits allows people to tailor their look in hopes of attracting or avoiding attention. New research led by the University of Washington found that hummingbirds may take a similar approach.

California produces 99% of the nation's pistachios, generating nearly $3 billion in economic value in the state. But pistachios have been slightly understudied, in part because of the lack of a high-quality map of their DNA.

Northwestern Medicine investigators have uncovered new insights into how intercellular "glue" functions to enable interactions between cells, as detailed in a study published in Nature Communications.

Residents of the Tuscany beach enclave of Orbetello are seeking a state of emergency declaration to help combat an invasion of midges that are keeping people indoors and threatening businesses catering to tourists.

While researchers have long been familiar with the surface structure of lymphatic vessels, a groundbreaking study has now focused on their jigsaw puzzle-like pattern. This arrangement helps cells tolerate changes in fluid pressure, such as swelling. Similar cell shapes are found on the surface of plant leaves, and the principle has been employed in human-led design as well.

Researchers have discovered that an enzyme can serve as an ideal target for developing new therapeutics against Lyme disease, and most likely other tick-borne diseases as well.

Adverse genetic mutations can cause harm and are due to various circumstances. 'Jumping genes' are one cause of mutations, but cells try and combat them with a specialized RNA called piRNA. Researchers have identified how the sites responsible for piRNA production evolve effective behaviors against jumping genes. This research could lead to downstream diagnostic or therapeutic applications.

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.

Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic development of the chicken, researchers from the University of Geneva (UNIGE) have uncovered a key role of a molecular signalling pathway (the Shh pathway) in their formation. This research provides new insights into the morphogenetic mechanisms that led to feather diversification throughout evolution.

A research team led by Prof. Liu Xuanyong from the Shanghai Institute of Ceramics of the Chinese Academy of Sciences has introduced a pioneering antibacterial strategy that disrupts bacterial energy metabolism by interfering with proton and electron transfer in bacterial membranes.

Mitochondria are the powerhouses in our cells, producing the energy for all vital processes. Using cryo-electron tomography, researchers at the University of Basel, Switzerland, have now gained insight into the architecture of mitochondria at unprecedented resolution.

Feathers are among the most complex cutaneous appendages in the animal kingdom. While their evolutionary origin has been widely debated, paleontological discoveries and developmental biology studies suggest that feathers evolved from simple structures known as proto-feathers.

Spanish lawmakers on Thursday voted to end a ban on hunting wolves in the north of the country, three years after its introduction by Prime Minister Pedro Sanchez's minority leftist government.

Biomedical engineers at Duke University have developed a 3D imaging method to precisely map and categorize the social behavior of animals. By quantitatively measuring the movements, interactions, and body contacts between rodents, the scientists were able to reveal for the first time how several different genetic forms of autism affected social behavior in rats.

Protecting native forests combined with transitioning fallow and unmanaged agricultural lands to 'Ōiwi (Native Hawaiian) and other place-based agroforestry systems has direct benefits for local fisheries, according to a new study published in npj Ocean Sustainability by an interdisciplinary team from the University of Hawai'i at Mānoa, Institute of Pacific Islands Forestry, Kamehameha Schools and Seascape Solutions.

Just as cities must carefully manage the flow of cars in and out of downtown, cells regulate the movement of molecules into and out of the nucleus. This microscopic metropolis relies on an intricate gateway—facilitated by nuclear pore complexes (NPCs) within the nuclear envelope—to control its molecular traffic.

Our skin and mucous membranes are protected by epithelial cells. This barrier tissue performs its function thanks to specialized structures called junctions. They ensure cell cohesion and regulate exchanges across the space between cells.

Forests provide many ecosystem services, including microclimate regulation, biodiversity preservation, air and water purification, and soil protection. Together with the oceans, they are one of the two most important carbon sinks, due to their capacity to store carbon in the soil and in tree biomass.

Researchers from the University of Bayreuth have discovered the mechanism by which collagen, the most common protein in the human body, successfully assembles itself. They identified electrostatic forces that support this self-organization and contribute to the stability of the protein.
