There are only two mammals on Earth with the proven ability to move their bodies in time with an external beat, which are humans and sea lions. Some researchers at the University of Santa Cruz rescued a stranded sea lion in 2013, which was a California sea lion called Ronan. Ronan is the first non-human mammal convincingly shown to be able to keep the beat. Scientists at Pinniped Cognition and Sensory Systems Laboratory trained Ronan to bob her head in time with the rhythmic sounds, then showed that she could transfer this skill to tempos and music that she hadn't heard before. When the beat sped up or slowed down, so did the bops of Ronan’s head and when “Boogie Wonderland” by Earth, Wind & Fire started playing over the speakers, Ronan kept perfect time. According to Peter Cook, a graduate student in psychology at UC Santa Cruz, Ronan's sense of rhythm undercuts an increasingly influential theory that beat keeping requires a capacity for complex vocal learning. Sea lions have limited flexibility in the sounds they make and they are not known to be capable of vocal mimicry. "Ronan's success poses a real problem for the theory that vocal mimicry is a necessary precondition for rhythmic entrainment," Cook said. These sea lions should be trained as soon as possible by starting with simple rhythm tracks. ‘’Sea lions are also good at finding the tempo in music, but don’t seem to maintain the behavior as reliably as Ronan. She stays right on the beat’’, Cook also said. From this information, we know that actually sea lions are also good at dancing to a beat even though it will take a few months for them reliably keeping the beat, but once they had mastered it, surely they will show a remarkable ability to keep time to novel rhythmic tempos and music and also dancing by bobbing their heads up and down. For those who are still not believe that sea lions can dance to a beat, let’s take a look and read this useful information.

Food waste and food loss have a significant impact on global warming. When wasted food goes to the landfill, it rots and emits greenhouse gases that damage our environment. Each year, 3.3 billion tons of carbon dioxide are emitted because of food waste.

To put this into perspective, if wasted food were a country it would be the third largest producer of carbon dioxide in the world after the U.S. and China. Today, 811 million people don’t know where their next meal is coming from while tons of perfectly edible food rots in landfills and poor storage containers. Reducing food waste and losses is key to ending global hunger, fighting climate change and fostering healthy food systems and every person can be part of the solution.

By taking small steps to reduce food waste, like eating leftovers and only buying the food that you need. Can helps fight global hunger and climate change. 

Dull knives, however, can't cut through food easily, and often cause injuries when resistance between the dull blade and the food's surface suddenly gives way, at which point the knife flies out of control. Since you have to use so much pressure to cut with a dull knife, they often cause deep cuts and gouges, as opposed to the minor nicks a sharper knife might inflict. Keep your knives sharp and hone those skills for maximum safety.
