HON CHEMISTRY: Hey guys, welcome to chemical bonds! How did you do on using electronegativity to determine bond type? Make sure you add the scale and also the diatomic molecules to your “things I have to memorize and know how to use for the test” list.

This article talks about relativity- how it was found and what it is. It was postulated by Albert Einstein in 1915. Einstein stated that anything with mass warps spacetime and causes a distortion. He called this distortion gravity. The distortions are curves too. Today we are still observing things that Einstein said were true.

This article says that traces of bird flew is being found in cows milk in grocery stores. Thanks to the fact that most milk pasteurized, humans most likely won’t be infected by the virus. Milk pasteurization increases the temperature of milk to a point that it will kill all the viruses and bacteria. The FDA stressed that we don’t drink raw milk, only pasteurized milk.

This article talks about how the noises of everyday life can harm animals. Everyday noise pollution can cause them serious problems. Depending on how long and when they were exposed to these noises can cause different effects on them. These problems were not short term and lasted for most of their lives.

In 2019, a team of scientists went to the Quebrada Chorro forrest in Panama to study the roots of a tropical conifer; they ended up discovering something interesting about Cyathea rojasiana tree ferns. They found that the dead leaves of the fern that had fallen around the bush were rooted into the soil. To test if the “dead” leaves had actually sprouted roots, they brought the leaves back to a lab and planted them in soil and monitored if they pulled nutrients from the soil. When soil was indead pulled into the leaves, it was confirmed that the formations on the tips of the leaves were truly roots. There have been interesting discoveries about the leaves of ferns before, but this was the first time a dead leaf had been discovered to root into soil and come back to life.

The article discusses the potential of ocean-based carbon removal methods to mitigate climate change. It explores various techniques such as ocean fertilization, algae farming, and direct air capture, which aim to draw down carbon dioxide from the atmosphere and store it in the ocean. These methods have the potential to sequester significant amounts of carbon, but they also pose risks to marine ecosystems and may have uncertain long-term effects. Scientists emphasize the need for thorough research and regulation to ensure that these approaches are safe and effective. However, concerns remain regarding the scalability, environmental impact, and ethical considerations of large-scale ocean carbon removal projects.

The article talks about how by tinkering with the oceans chemistry we could use it to absorb more carbon than it already is. By doing this it’s would allow us to increase the amount of carbon that we can absorb as the ocean can take in about 19 times the amount of carbon dioxide than we can on land. Already it takes in about a quarter of the carbon dioxide in the air but if we could increase how much it absorbs then we could essentially give ourselves more time.

A new study came out that bone marrow cells and heart disease have a connection. Scientists discovered that macrophages, certain bone marrow cells, can develop a major cause in heart disease. They produce inflammation and plaque build up in the blood vessels worsening your heart.

This week I have struggled with doing my out of class work. I keep pushing off watching the videos on the elements that I need to know for the test. To overcome this struggle, I have given myself a set deadline to get it done. I hope to get these done by that day so I do not have to worry about them later!
