The study, led by the University of York, found evidence for a period of enhanced pre-industrial sea-level rise of about two to three millimetres per year in three locations: Nova Scotia, Maine and Connecticut.
The researchers say that the large rises at these three locations were natural, and partly related to the North Atlantic Oscillation - a large-scale atmospheric pressure see-saw over the North Atlantic region - and to periods of enhanced ice melt in the Arctic.
Using microscopic video analysis, a research group from Kumamoto University, Japan has provided deeper insight into the mechanics of plant cell division. The video reveals that the shape of phragmoplasts--cell structures that create the partition between two dividing plant cells--is controlled by actin filaments.
Freising/Germany - Researchers at the Leibniz-Institute for Food Systems Biology at the Technical University of Munich (Leibniz-LSB@TUM) have confirmed the presence of the rare amino acid ethionine in a plant - or more precisely, in the fruit of the durian tree. Despite its pungent odor, durian is very popular in Southeast Asia. As the team of scientists has shown, the amino acid plays a key role in the formation of the characteristic durian odor.
A research team has uncovered a genetic signature that enables cells to adapt their protein production according to their state. The researchers of the University of Basel's Biozentrum report in Genome Biology that this newly discovered mechanism plays a role in the regulation of protein production during cell division.
The spatial arrangement of genetic material within the cell nucleus plays an important role in the development of an organism. A research team from the University of Basel, in collaboration with scientists from Harvard University, has developed a method to trace the chromosomes in individual cells. Using this method, they have now been able to demonstrate that chromosomes reorganize during embryonic development. The study has recently been published in Molecular Cell.
A new study in the journal Science has given insight into why the world's oceans are full of more species than ever before - a question that has long been a focus of paleontological research.
The most diverse kinds of animals in the modern oceans, such as fish, mollusks, and crustaceans, diversified slowly and steadily for long periods of time, and were buffered against extinction.
Please Note: The 2020 American Physical Society (APS) March Meeting that was to be held in Denver, Colorado from March 2 through March 6 has been canceled. The decision was made late Saturday (February 29), out of an abundance of caution and based on the latest scientific data available regarding the transmission of the coronavirus disease (COVID-19).

Researchers from the U.S. Army and North Carolina State University have developed a computational model that can be used to expedite military operations aimed at evacuating noncombatants, disaster response or humanitarian relief.
"What sets this tool apart from other models is that it is designed for use in both planning and during operations," says Brandon McConnell, corresponding author of a paper on the new model and a research assistant professor in NC State's Edward P. Fitts Department of Industrial & Systems Engineering.
Researchers at Michigan Technological University and Brookhaven National Laboratory, along with partners at other universities, industry, and national labs, have determined that while the shape of particles containing black carbon does have some effect on atmospheric warming, it's important to account for the structural differences in soot particles, as well as how the particles interact with other organic and inor
Engineers from Far Eastern Federal University Military training center (FEFU, Vladivostok, Russia) together with colleagues from RUDN University have developed concrete mixture with nano additives for monolithic construction up to ten stories high. The concrete casting is possible within a very humid climate and negative temperature down to minus 5-degree centigrade. Given that, the constructed buildings will not require major renewal for 50 years. The related article is published in Construction and Building Materials.

Antioxidant supplements do not improve semen quality among men with infertility, according to a new study supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health. The study also found that antioxidant supplements likely do not improve pregnancy and live birth rates. The study appears in Fertility and Sterility.
Methane is a gas that deserves more attention in the climate debate as it contributes to almost half of human-made global warming in the short-term. A new IIASA study shows that it is possible to significantly contribute to reduced global warming through the implementation of available technology that limits methane release to the atmosphere.

LOGAN, UTAH, USA -- Why are there so many species of plants? Why do some plants thrive, while others don't?
People who eat a vegetarian diet rich in nuts, vegetables and soy may have a lower risk of stroke than people who eat a diet that includes meat and fish, according to a study published in the February 26, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
