The search of life beyond our world is an exciting venture that may yield an enormous discovery in the not-too-distant future. However, space agencies around the world, including NASA and the European Space Agency, have long been aware of the potential risks of biological contamination and have set in place planetary protection policies.

Concentrations of dissolved oxygen in the deep waters of the Lower St. Lawrence Estuary (LSLE) have dropped by over 50% over the past two years. The consequences for many marine species, who depend on oxygen to survive, are potentially very serious. A compilation of historical data reveals that dissolved oxygen concentrations in the deep waters of the Lower St. Lawrence Estuary decreased by about 50% during the fifty years between 1934 and 1985. And then remained fairly constant until 2019, when the situation changed dramatically.

In humans, the dopamine system has been tied to rewards and pleasurable sensations. As well as to memory and learning. A recent study from 香蕉视频, published in , suggests that dopamine may also play a key role in shaping what songs female songbirds enjoy, which may ultimately affect mating as females choose (and then remember) their mates based on the songs they prefer.

Surprising as it sounds, all life forms in the ocean, from small krill to large tuna, seem to obey a simple mathematical law that links an organism鈥檚 abundance to its body size. For example, although small krill are individually only about one millionth of the weight of a large tuna, they also tend to be a million times more numerous throughout the oceans. The idea, known as the Sheldon size spectrum theory, was first advanced in the 1970s, but has never been tested for a wide range of marine species and on a global scale until now.

A team of computer scientists, including Claude Cr茅peau of 香蕉视频 and physicist colleagues from the University of Geneva, have developed an extremely secure identity verification method based on the fundamental principle that information cannot travel faster than the speed of light. The breakthrough has the potential to greatly improve the security of financial transactions and other applications requiring proof of identity online.

The mussels鈥� beards (which cooks remove before preparing them) are made up of byssal threads and are used to help keep the mussels tethered in place. At the end of each thread is a disc-shaped plaque that acts as an underwater glue. The unusual qualities of the glue and the byssal threads have interested people since ancient times, when the threads of certain species were woven into luxurious berets, purses, gloves, and stockings. More recently, scientists have developed underwater adhesives and surgical glues inspired by byssal thread chemistry.
