Tilapias living in crowded aquaculture ponds or small freshwater reservoirs adapt so well to these stressful environments that they stop growing and reproduce at a smaller size than their stress-free counterparts.
A new study by researchers at the University of Kelaniya in Sri Lanka and the University of British Columbia, explains that while most fishes die when stressed, tilapias survive in rough environments by stunting and carrying on with their lives in dwarf form.
A research team of the National Institutes of Natural Sciences, National Institute for Fusion Science and Akita Prefectural University have successfully demonstrated a broadband mid-infrared (MIR) source with a simple configuration. This light source generates highly-stable broadband MIR beam at 2.5-3.7 μm wavelength range maintaining the brightness owing to its high-beam quality. Such a broadband MIR source facilitates a simplified environmental monitoring system by constructing a MIR fiber-optic sensor, which has the potential for industrial and medical applications.
New research shows how drinking sugary beverages early in life may lead to impaired memory in adulthood.
The study, published today in Translational Psychiatry, also is the first to show how a specific change to the gut microbiome -- the bacteria and other microorganisms growing in the stomach and intestines -- can alter the function of a particular region of the brain.
Transport Network Companies (TNCs) not only increased road congestion but were also net substitute for public transit reducing PT ridership by almost 9%
The reduction in private vehicle ownership due to TNCs was insignificant
Research findings can provide valuable insights for transportation policy and regulation
Until now, researchers have believed that dark energy accounted for nearly 70 percent of the ever-accelerating, expanding universe.
For many years, this mechanism has been associated with the so-called cosmological constant, developed by Einstein in 1917, that refers to an unknown repellant cosmic power.
But because the cosmological constant--known as dark energy--cannot be measured directly, numerous researchers, including Einstein, have doubted its existence--without being able to suggest a viable alternative.
Tropical cyclones -- known as typhoons in the Pacific and as hurricanes in the Atlantic -- are fierce, complex storm systems that cause loss of human life and billions of dollars in damage every year. For decades, scientists have studied each storm, striving to understand the system yet unable to fully measure every intricate variable. Now, the convergence of new observational tools and the launch of an inclusive database may elucidate the innerworkings of tropical cyclones in the Western North Pacific and South China Sea.
Tokyo, Japan - A research team from the Institute of Industrial Science, The University of Tokyo has conducted a detailed analysis of the uncertainties associated with flood risk modeling at the global scale. They found large uncertainties were mainly associated with runoff data. Flood magnitude is large in wet regions, but uncertainties in flood depth is larger in dry and mountainous regions affected by rare, extreme floods. The results of the study can be used to identify the key areas for improvement in hydrological modeling and improve future predictions of flood risk.
A team of Nanyang Technological University, Singapore (NTU Singapore) researchers has designed a 'smart' device to harvest daylight and relay it to underground spaces, reducing the need to draw on traditional energy sources for lighting.
In Singapore, authorities are looking at the feasibility of digging deeper underground to create new space for infrastructure, storage, and utilities. Demand for round-the-clock underground lighting is therefore expected to rise in the future.
Ishikawa, Japan - The focus and ultimate goal of computational research in materials science and condensed matter physics is to solve the Schrödinger equation--the fundamental equation describing how electrons behave inside matter--exactly (without resorting to simplifying approximations). While experiments can certainly provide interesting insights into a material's properties, it is often computations that reveal the underlying physical mechanism.
A new report is highlighting ways we can fight COVID-19 while indoors during cold weather periods.
At the beginning of the COVID-19 crisis, there was a lack of empirical evidence on the virus's airborne transmission. However, an increasing body of evidence - gathered particularly from poorly ventilated environments - has given the scientific community a better understanding of how the disease progresses. Information on the asymptomatic and pre-symptomatic transmission of the virus strongly supports the case for airborne transmission of COVID-19.
KANSAS CITY, MO--Since the beginning of the pandemic, a loss of smell has emerged as one of the telltale signs of COVID-19. Though most people regain their sense of smell within a matter of weeks, others can find that familiar odors become distorted. Coffee smells like gasoline; roses smell like cigarettes; fresh bread smells like rancid meat.
One specific protein may be a master regulator for changing how cancer cells consume nutrients from their environments, preventing cell death and increasing the likelihood the cancer could spread, a study from the University of Notre Dame has shown.
The study, published in Cell Reports, was completed in the laboratory of Zachary Schafer, the Coleman Foundation Associate Professor of Cancer Biology in the Department of Biological Sciences.
The study, published in Nature Geoscience, produced a global model mapping pollution risk caused by 92 chemicals commonly used in agricultural pesticides in 168 countries.
The study examined risk to soil, the atmosphere, and surface and ground water.
The map also revealed Asia houses the largest land areas at high risk of pollution, with China, Japan, Malaysia, and the Philippines at highest risk. Some of these areas are considered "food bowl" nations, feeding a large portion of the world's population.
Superconductivity is known to be easily destroyed by strong magnetic fields. NIMS, Osaka University and Hokkaido University have jointly discovered that a superconductor with atomic-scale thickness can retain its superconductivity even when a strong magnetic field is applied to it. The team has also identified a new mechanism behind this phenomenon. These results may facilitate the development of superconducting materials resistant to magnetic fields and topological superconductors composed of superconducting and magnetic materials.
