For the first time in Brazil, scientists have identified the presence of bacteria that cause columnaris disease, a serious disease in farmed fish intended for human consumption. Previously, different species of the genus Flavobacterium had only been detected in fish farms in
Finding water on the moon may only be a matter of detecting the right vibrations.
We know Mars has water ice in its polar regions, but astronauts (and their solar-powered equipment!) would much rather experience life closer to Mars' equator. As NASA looks toward landing humans on the red planet, the Planetary Science Institute (PSI) is mapping where water
Grounding intermittent art festivals such as the Setouchi Triennale within the resource capacities and social thresholds of the island communities that host them is a path to the sustainable, long-term revitalization of these communities.
Recirculating aquaculture systems (RAS) are attracting growing attention as a sustainable aquaculture technology that can reduce water use, control rearing conditions and lower environmental impacts by filtering and reusing water. At the same time, RAS facilities rely on pumps,
The human genome contains more than 20,000 genes. However, at any given time and in a given cell, only a fraction are active. Researchers from EMBL Heidelberg's Krebs Group have developed an innovative experimental approach to understand how cells determine which genes to turn

Climate change, land-use change and socioeconomic pressures are turning wildfires from a primarily ecological process into a complex, systemic risk that cuts across ecosystems, infrastructure, public health, water resources, cultural heritage and rural livelihoods. Despite
Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect the two newly formed cells.
A map showing the distribution of isotopes in Amazonian tree wood can help identify illegally harvested timber. By analyzing the ratio of different isotopes of elements such as oxygen, carbon, nitrogen and strontium, researchers can pinpoint the region where the wood was

Two organisms inhabiting a common environment can sometimes mutually influence each other, either benefiting or, in some cases, damaging one another. This mutually beneficial or ambivalent biological relationship is known as symbiosis.
AFPA has echoed serious concerns raised by Forestry Australia over the federal government's controversial new carbon credit method, warning it undermines the integrity and credibility of Australia's carbon market.
Researchers at the University of Tartu have discovered a mechanism in bacteria that helps them adapt to fluoride, which is toxic to most organisms above relatively low threshold concentrations. Their discovery may represent a significant milestone in bioindustry, as it could
New wildfires fed by strong winds broke out in Greece on Friday, giving firefighters little respite and forcing Civil Protection officials to order the partial evacuation of part of a suburb west of Athens.
Much like caviar, shark fins are a luxury product and delicacy in parts of the world. And like wild caviar, demand for shark fins has posed an incredible threat to species that can't reproduce quickly enough to keep up.
The high frequency of RNA virus mutations and outbreaks of emerging RNA viral infections are challenging public health issues. Developing a drug that can overcome viral mutations with broad-spectrum antiviral activity is an unmet need.
Scientists have discovered a remarkably well-preserved 100-million-year-old beetle fossil that provides a rare glimpse into the evolution of the intricate sensory and communication systems used by fireflies and their relatives today. Fireflies belong to the order Coleoptera,
A study by researchers in the UAB Department of Mathematics and the Center for Mathematical Research (CRM) presents a model describing the behavior of encapsulated bacteriophages within the gastrointestinal tract. Its objective is to better understand the advantages and
A study led by Marc Guinjoan, a lecturer in the Department of Political Science and Public Administration at the UAB, with researchers Toni Rodon of the UPF and Joel Ardiaca of the UB, reveals that citizen support for climate policies depends largely on how the costs, benefits
Facing wind and cold, with only half as much oxygen to breathe as in the valley, a German-Turkish research team surveyed the glacier on Mount Ararat in eastern Turkey for the first time in July, at more than 5,000 meters (16,400 feet) above sea level. For two weeks, the team
The performance of many next-generation devices depends on controlling how energy flows at extremely small scales. In the field of microelectronics—where devices continue to shrink and new materials are introduced—small imperfections in solids can strongly influence how a
The COVID-19 pandemic highlighted severe consequences of unchecked respiratory disease, including cytokine storms. This phenomenon affected many COVID-19 patients and is a potential side effect of many other diseases involving significant inflammation, but approaches to

Adorning the walls of San Ildefonso College in Mexico City is artist Diego Rivera's masterpiece, rendered in fresco and gold leaf, The Creation, or La Creacioń. It depicts a man standing with his arms outstretched beneath a deep blue celestial disk studded with stars and
A new Concordia study has demonstrated a greener way to produce an important class of catalytic materials with promising potential for cleaner energy technologies that rely more on acoustic energy than water and chemicals. The work is published in the journal Advanced Synthesis
PFAS, otherwise known as forever chemicals, have become commonplace in numerous everyday and industrial products. At the same time, they are some of the most problematic pollutants of our times: They are extremely durable, accumulate in the environment and in organisms and can
Scorching summer temperatures have disrupted life for millions of Europeans, but for winegrowers in Italy and France who are harvesting their grapes unusually early, the hot weather offers pros as well as cons.
A drifting SpaceX rocket is on a collision course with the moon after launching a pair of lunar landers more than a year ago.
An international team of volcanologists working on Carlingford Mountain has found that liquid "magma chambers" do not always exist beneath volcanoes. The team instead demonstrated that magma "plumbing systems" beneath Earth's surface can fluctuate between solid- and
A protein that is a hallmark of Alzheimer’s disease may also ID a brain condition associated with head trauma in contact sports, early findings suggest.
