Approximately one million seabirds on the west coast of the U.S. died due to an unprecedented marine heatwave in the Pacific Ocean.
Known as “the blob”, the heatwave caused sea surface temperatures along the Pacific coast of North America to rise by 1-2°C.
The fish that common guillemots normally eat, such as herring, sardine and anchovy, either died or moved into cooler waters elsewhere, leaving the guillemots with little to eat. As a result, many birds starved.
The appearance of unusually high numbers of dead birds washed up on the shoreline is referred to as a “wreck”.
Researchers have discovered a key piece of the puzzle about the origin of life on the Earth with the discovery of how phosphorus-bearing molecules, essential for cell metabolism, may have reached the planet from space.
Astronomersused data from the ROSINA instrument on board the Rosetta spacecraft to show that the chemical phosphorus monoxide is a key piece in the origin-of-life puzzle.
The studyalso used data acquired by a network of 66 radio telescopes in the Atacama Desert of northern Chile called the Atacama Large Millimetre/Submillimetre Array (ALMA).
The finding of phosphorus on comets helped astronomers draw the first connection between star-forming regions in space, where phosphorous molecules are created and how these are transported all the way to the Earth.
A study has found that heart rate and sleep data from wearable fitness tracker watches can predict and alert public health officials to real-time outbreaks of flu more accurately than current surveillance methods.
The World Health Organization estimates that as many as 6,50,000 people worldwide die of respiratory diseases linked to seasonal flu each year.
Traditional surveillance reporting takes up to three weeks, meaning response measures such as deploying vaccines or anti-virals and advising patients to stay at home can often lag.
