Water layering is intensifying significantly in about 40% of the world's oceans, which could have an impact on the marine food chain. The finding, published in the Journal of Geophysical Research: Oceans, could be linked to global warming.
Tohoku University geophysicist Toshio Suga collaborated with climate physicist Ryohei Yamaguchi of Korea's Pusan National University to investigate how upper-ocean stratification has changed over a period of 60 years.
The Atlantic Ocean acts as a key pacemaker for Middle East surface air temperature (ME-SAT) multidecadal variability in summer. This is the important result of a study published on NPJ Climate and Atmospheric Science unveiling and demonstrating the existence of a North Atlantic-Middle East teleconnection, that is a remote influence of the Atlantic multidecadal variability on the decadal variability of Middle East summer temperatures.
The consumption of sugar is a fundamental source of fuel in most living organisms. In the malaria parasite Plasmodium falciparum, the uptake of glucose is essential to its life cycle. Like in other cells, sugar is transported into the parasite by a transport protein - a door designed for sugar to pass through the cell membrane. The details in how this door works has now been revealed.
(Philadelphia, PA) - When it comes to finding new treatments for disease, reinventing the wheel is not always necessary - drugs already in use for other conditions may do the job. And if it turns out that a pre-existing drug works, getting it approved for the treatment of another disease can happen much more quickly than for entirely new drugs never previously tested in people.
BURLINGTON, VT--What do we really know about reasons attributed to the success or failure of wildlife management efforts? A new study originating out of UVM suggests a disquieting answer: much less than we think.
Four hours east of Medellin in northern Colombia's Puerto Triunfo municipality, the sprawling hacienda constructed by infamous drug lord Pablo Escobar of "Narcos" fame has become a tourist attraction. When Escobar's empire crashed, the exotic animals housed at his family's zoo, including rhinos, giraffes and zebras, were safely relocated to new homes... except for the hippopotamuses.

After conducting a field trial at a tomato farm near Ravenna, Italy, a team of plant pathologists and agronomists found that nitrogen fertilizers shape the composition and predicted functions of the plant microbiota. The microbiota refers to the community of microorganisms found in the interface between the soil and the roots of a plant. Similarly to the human digestive tract, the microbiota can help or hinder the plant's nutrition as it is responsible for the uptake of minerals from the soil.
The Khaled bin Sultan Living Oceans Foundation has published their findings from extensive coral reef surveys conducted in the Kingdom of Tonga. Released today, the Global Reef Expedition: Kingdom of Tonga Final Report contains critical information on the health and resiliency of coral reef ecosystems in Tonga, and provides scientists, policymakers, and stakeholders with invaluable information they can use to protect these fragile marine ecosystems.
ITHACA, N.Y. - Just when it seemed like robots couldn't get any cooler, Cornell University researchers have created a soft robot muscle that can regulate its temperature through sweating.
This form of thermal management is a basic building block for enabling untethered, high-powered robots to operate for long periods of time without overheating, according to Rob Shepherd, associate professor of mechanical and aerospace engineering at Cornell, who led the project.
Expanding Medicaid in North Carolina could sharply lessen the burden of colon cancers in the state and save the lives of thousands of Black men as well as improving access to care for men of all races, researchers report in the 27 January issue of PLOS ONE.
Although a link has been established between chronic inflammation and neurodegenerative diseases, there have been many open questions regarding how cellular senescence, a process whereby cells that stop dividing under stress spew out a mix of inflammatory proteins, affects these pathologies.
Drastic ecosystem interventions like eradicating an unwanted species can sometimes backfire, but new University of Queensland-led modelling may help to avoid these ecological hiccups.
Dr Matthew Adams, from UQ's School of Earth and Environmental Sciences, said despite all good intentions, ecological interventions can have devastating consequences.
"It would be great if we could simply assume that eradicating an invasive species from a natural environment is always a good thing," Dr Adams said.
Using genetically engineered human pluripotent stem cells, University of California San Diego School of Medicine researchers created a new type of cancer model to study in vivo how glioblastoma, the most common and aggressive form of brain cancer, develops and changes over time.
To improve behavior in class, teachers should focus on praising children for good behavior, rather than telling them off for being disruptive, according to a new study published in Educational Psychology.
Researchers spent three years observing 2,536 students, across three US states, from kindergarten age through to sixth grade (5 to 12 years of age).
Researchers are at work to find effective treatments to help young patients with brain tumors. Hundreds of brain organoids have been developed in the laboratories of the University of Trento to understand the genetic mechanisms responsible for these hard to treat diseases.
In this way, the research team coordinated by Luca Tiberi of the Armenise-Harvard Laboratory of Brain Disorders and Cancer of Cibio Department of the University of Trento developed a new strategy to study brain tumors of childhood.
