Seaport footprints will need to expand by up to 3,689 square kilometers (1,424 square miles) worldwide in the next three decades to cope with the combination of sea-level rise and rising demand, according to a new study published in Earth's Future, a peer-reviewed scientific journal focusing on climate change and future sustainability.
Climate change could deliver more silt, sand and pollution to the San Francisco Bay-Delta, along with a mixed bag of other potential consequences and benefits, according to a new study in the AGU journal Water Resources Research, which publishes research articles and commentaries providing a broad understanding of the role of water in Earth's natural systems.
All cancers are the result of cells that have gone haywire, multiplying out of control and expanding beyond their normal constraints. But not all tumors are the same: for reasons that remain poorly understood, some are more likely to become aggressive and metastasize to other parts of the body.
Many relatives who experience severe long-term grief reactions after bereavement have more frequent contact with their general practitioner already prior to bereavement, as well as a higher consumption of antidepressants and sedatives than those who have fewer critical symptoms of grief over time. This suggests that it may be possible to prevent this by catching this group earlier. This is shown by a new research result from Aarhus University.
Toronto/Armidale, September 1, 2020 - How do you weigh a long-extinct dinosaur? A couple of ways, as it turns out, neither of which involve actual weighing -- but according to a new study, different approaches still yield strikingly similar results.
New research published September 1 in the prestigious journal Biological Reviews involved a review of dinosaur body mass estimation techniques carried out over more than a century.
The Sun is our star and has a profound influence on our planet, life, and civilization. By studying the magnetism on the Sun, we can understand its influence on Earth and minimize damage of satellites and technological infrastructure. The GREGOR telescope allows scientists to resolve details as small as 50 km on the Sun, which is a tiny fraction of the solar diameter of 1.4 million km. This is as if one saw a needle on a soccer field perfectly sharp from a distance of one kilometer.
In early June 2011, NOAA Fisheries researchers and colleagues placed satellite tags on 26 loggerhead sea turtles in the Mid-Atlantic Bight. The tagging was part of ongoing studies of loggerhead movements and behavior. The Mid-Atlantic Bight, off the U.S. East Coast, is the coastal region from Cape Hatteras, North Carolina to southern Massachusetts. A little more than 2 months later, on August 28, Hurricane Irene passed through the area, putting 18 of the tagged turtles in its direct path.
In laboratory studies, Johns Hopkins Kimmel Cancer Center and Johns Hopkins University researchers observed a key step in how cancer cells may spread from a primary tumor to a distant site within the body, a process known as metastasis.
There's more to seawater than salt. Ocean chemistry is a complex mixture of particles, ions and nutrients. And for over a century, scientists believed that certain ion ratios held relatively constant over space and time.
The act of giving and receiving increases well-being: the recipient benefits directly from the gift, and the giver benefits indirectly through emotional satisfaction. A new study published in the journal PNAS now suggests that those who share more also live longer. In their analysis, Fanny Kluge and Tobias Vogt found a strong linear relationship between a society's generosity and the average life expectancy of its members.
SCIENTISTS LOOK TO CELL RECYCLING TOOLS FOR NEW WAYS TO TREAT PARKINSON'S DISEASE

Researchers at Johns Hopkins Medicine are taking a closer look at the molecular machinery that recycles mitochondria, the cell's powerhouse, in efforts to ramp up the production of the energy-producing structures. Problems with mitochondria are a key aspect in the development of Parkinson's disease.
Marine animals are notoriously difficult to track, creating big gaps in how scientists understand their behavior and migration patterns - key insights for helping conserve important habitats. Researchers in Australia, using satellite tags and a decades-old satellite photographic database, published a paper in Frontiers in Marine Science that suggests a migratory species like the reef manta ray is somewhat of a homebody.
There are memory cells that remember previously encountered pathogens and help to react quickly and strongly when exposed to them again. The developmental process of strong immune cells that make these memory cells in advance without having to encounter the pathogens have been discovered.
Mite extinctions are occurring at least 1,000 times the 'natural' rate - a finding a University of Queensland researcher says is another warning that global biodiversity is in deep trouble.
The 1.25 million mite species around the planet occupy an enormous variety of terrestrial and freshwater ecosystems, from the equator, to polar regions and high altitude areas.
In the first global study on mite biodiversity, UQ's Dr Greg Sullivan and colleague Dr Sebahat K. Ozman-Sullivan compiled data that showed the ongoing extinction of an alarming number of species.
Chinese people have been paying more and more attention to water safety, especially since the Wuxi "water crisis" in Lake Taihu in 2007. However, more than 10 years after the crisis, how healthy are Chinese lakes now?
