Over the past 50 years, the water in lakes and watercourses has turned increasingly brown. The so-called browning has a negative impact on both drinking water production and ecosystems. If nothing is done, the water is likely to turn even browner - however, there is hope.
Supported by a new study, researchers from Lund University and the Swedish University of Agricultural Sciences (SLU) are pointing to measures that could be taken with the purpose of mitigating and, in the long term, reversing this development.
Ice sheet dynamics of the past likely caused fault movements in the Earth's crust, resulting in seabed methane release in ~1200 m water depth offshore Svalbard, an archipelago in the Norwegian Arctic.
- Our results show similar patterns over the last two ice ages, from 160,000 years ago through today. The new data suggest a link between changing continental ice volumes and deep-sea methane emission in the Arctic, says Tobias Himmler, researcher at the Geological Survey of Norway (NGU) and principle author of the study.
Seabed and sub-seabed samples reveal the past
Jupiter's moon Io is the most volcanically active body in our solar system. Today, there are indications that an active moon outside our solar system, an exo-Io, could be hidden at the exoplanet system WASP-49b.
Plant genetic varieties in Central Europe could collapse due to temperature extremes and drought brought on by climate change. According to a new paper published in Nature today, only a few individuals of a species have already adapted to extreme climate conditions. These findings suggest that the overall species genetic diversity could be greatly diminished. The publication was led by Moises Exposito-Alonso, who joins Carnegie next month from the Max Planck Institute for Developmental Biology and the University of California Berkeley.
By analysing the fossilised teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants for longer periods than their contemporary relatives.
The results, published in the journal Science Advances, provide a first insight into the practice of weaning that remain otherwise unseen in the fossil record.
Watching paint dry may seem like a boring hobby, but understanding what happens after the paint dries can be key in preserving precious works of art.
The formation of metal soaps in artwork composed with oil paints can cause "art acne" - including pimpling and more severe deterioration - which poses a pressing challenge for art conservation around the globe.
It is affecting the works of Georgia O'Keefe, Vincent Van Gogh, Francisco de Goya, and Jackson Pollock, among many others, and researchers haven't yet found a good solution to stop its effects.
Jugglers are skilled at keeping several objects in motion at the same time using a combination of tossing motions and eye movement. As objects are added to a juggler's routine, their gaze moves as the juggler tries to focus on all of the objects and avoid dropping one or two.
Legend states that after the Greek army defeated the invading Persian forces near the city of Marathon in 490 B.C.E., the courier Pheidippides ran to Athens to report the victory and then immediately dropped dead. The story — and the distance Pheidippides covered — inspired the modern marathon, a grueling 26.2-mile contest that attracts some 1.3 million runners annually to compete in the more than 800 races held worldwide.
WASHINGTON - New research finds Arctic Ocean currents and storms are moving bacteria from ocean algae blooms into the atmosphere where the particles help clouds form. These particles, which are biological in origin, can affect weather patterns throughout the world, according to the new study in the AGU journal Geophysical Research Letters.
MADISON -- In early mammalian development, timing is everything.
For healthy development to occur -- whether it be three weeks for a mouse or nine months for a human -- embryos follow the lead of oscillating genes, which turn on and off in precise cycles and trigger different development milestones. Oscillating genes are conductors keeping time in a symphony of growth.
