How summer 2019 was hellish for the Arctic, the frontline of climate change and global warming – Euronews
Winter is coming slowly to the Arctic. With the arrival of the autumn, the region will set into darkness and the ice and sun will have a truce after another dreadful melt season. Outside of major anomalies occurring, the ice…

Carp aquaculture in Neolithic China dating back 8,000 years
Researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.
Look out, invasive species: The robots are coming
Researchers published the first experiments to gauge whether biomimetic robotic fish can induce fear-related changes in mosquitofish, aiming to discover whether the highly invasive species might be controlled without toxicants or trapping methods harmful to wildlife. Their findings indicate that even brief exposure to a robotic replica of the mosquitofish’s primary predator can provoke meaningful avoidance behaviors and physiological changes associated with the loss of energy reserves, potentially translating into lower rates of reproduction.
New study shows common carp aquaculture in Neolithic China dating back 8,000 years
(Max Planck Institute for the Science of Human History) In a recent study, an international team of researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.
Critical Tipping Point Crossed In July 2019
In July 2019, a critical tipping point was crossed. July sea surface temperatures on the Northern Hemisphere were 1.07°C above what they were during the 20th century, as illustrated by above image which has a trend added that points at…
Drought reveals 'Spanish Stonehenge'
It all depends on the water level. If there’s been plenty of rain, there’s nothing out of the ordinary to be seen in the Valdecañas Reservoir in the province of Cáceres, Spain. But as conditions start to dry up, the…
A precise chemical fingerprint of the Amazon
This novel drone-based chemical monitoring system tracks the health of the Amazon in the face of global climate change and human-caused deforestation and burning.
Electric eel produces highest voltage discharge of any known animal
South American rivers are home to at least three different species of electric eels, including a newly identified species capable of generating a greater electrical discharge than any other known animal, according to a new analysis of 107 fish collected in Brazil, French Guiana, Guyana and Suriname in recent years.
Numerical simulations probe mechanisms behind sand dune formation
After noticing how the construction of dams significantly alter the hydrodynamics of natural rivers and the resulting downstream riverbed evolution, researchers decided to apply numerical simulations to help determine what’s at play in the relationship of sediment motion and flow conditions.
