Earth's oceans are home to some of the most diverse ecosystems on the planet, but warming temperatures are causing many marine animals, including coral, to die out.

A new study reveals that in U.S. cities over a several-year period, natural gas pipeline leaks were more prevalent in neighborhoods with low-income or majority non-white populations than those with high income or predominately white populations.
The declining body size of North Atlantic right whales may have critical consequences for the future of the species. New research shows that smaller females produce fewer calves.
The Human Cell Atlas sheds new light on the types and traits of immune cells that can be found in the human body, from developmental stages to adulthood.
Research could provide a new approach to treating an aggressive form of breast cancer. A study found that targeting the immune microenvironment in lymph nodes and tumors simultaneously led to long-term tumor remission in mice models of metastatic triple negative breast cancer.
The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami.
A study investigates the reasons for decreasing remission rates for patients with non-Hodgkin lymphoma treated with chimeric antigen receptor-T cell therapy (CAR-T cell therapy).
Scientists found a chemical from a rainforest tree that binds to opioid receptors in the brain and may have utility as an antidepressant or anti-anxiety drug.
The cnidocytes -- or stinging cells -- that are characteristic of sea anemones, hydrae, corals and jellyfish, and make us careful of our feet while wading in the ocean, are also an excellent model for understanding the emergence of new cell types, according to new research.
A new study finds that tree growth does not seem to be generally limited by photosynthesis but rather by cell growth. This suggests that we need to rethink the way we forecast forest growth in a changing climate, and that forests in the future may not be able to absorb as much carbon from the atmosphere as we thought.
A quantum system with only 51 charged atoms can take on more than two quadrillion different states. Calculating the system's behavior is child's play for a quantum simulator. But verifying the result is almost impossible, even with today's supercomputers. A research team has now shown how these systems can be verified using equations formulated in the 18th century.
Imagine sitting at a meeting where the shape of the table and your place at it might impact how you get along with the other members. Cells also communicate with their nearest neighbors, and in embryos, nothing is left to chance in the 'seating plan' for the first few cells. However, questions remain about the how this process is controlled and how it can influence the overall growth of an...
Researchers have equipped gut bacteria with data logger functionality as a way of monitoring which genes are active in the bacteria. These microorganisms could one day offer a noninvasive means of diagnosing disease or assessing the impact of a diet on health.
Genetic studies have revealed many genes linked to both common and rare disease, but to understand how those genes bring about disease and use those insights to help develop therapies, scientists need to know where they are active in the body. Research on single cells can help achieve this goal, by surveying gene activity in specific cell types. Scientists need to profile all cell types and...
Researchers have published a review of care for women with pre-eclampsia.
About one in 20,000 infants is born with what's called a congenital giant nevus -- a huge, pigmented mole that may cover much of the face and body. Due to the mole's appearance and its risk of later developing into skin cancer, many patients decide to have their children undergo extensive surgery to remove the entire lesion, which can cause large and permanent scars. Researchers led by recently...
A new study found that having three or more versus two children has a negative effect on late-life cognition. The results further indicated that this effect was strongest in Northern Europe, where higher fertility decreases financial resources but does not improve social resources in this region.
Researchers have evidence validating the benefits of using medication for opioid use disorder during pregnancy. Brain imaging revealed significant improvements in brain function after treatment.
Researchers are improving the odds for patients with the development of an implantable soft electronic vascular monitoring system. Their smart stent and printed soft sensors, is capable of wireless real-time monitoring of hemodynamics without batteries or circuits.
From embryo to turtle cracker: Palaeobiologists studied the multiple changes in tooth shape in the tiger shark. The study is also central in drawing conclusions about extinct species from the myriad of preserved shark teeth in the field of palaeontology.
New research on road cyclists sheds light on the importance of monitoring a training session load with the use of heart rate variability measuring tools, to favor assimilation and prevent injuries, and to compare training intensity with mood states the following morning.
Terrestrial laser scanning data show that trees move their branches in a diurnal pattern, settling down for the night -- as if falling asleep. Changes in the water status of leaves and branches causes branches to move downward at night, up to 20 cm depending on the tree species.
According to a new concept, it was a novel molecular species composed out of RNA and peptides that set in motion the evolution of life into more complex forms.
Anyone walking past a meadow on a mild summer evening is often exposed to an impressive concert. It is the grasshoppers, bush crickets and crickets that create a Mediterranean atmosphere with their chirping. The songs are usually those of males trying to attract females to mate with them. But they can also be rival songs when two males get too close to each other.
Serious auto crashes in urban areas are more likely on city streets that look to drivers like highways, new research suggests. The study used a novel approach: researchers applied machine learning techniques to analyze more than 240,000 images of road segments in Columbus, Ohio.
