As the population grows, environmentalists have become increasingly concerned about the future of the global food supply. Many sustainable options have been proposed, but none have quite taken hold. A group of researchers recently released a report on the crisis to show the exact scope.

By 2050, the expected world population of between 8.5 million and 10 million people will take a serious toll on the food supply. The team created a model to demonstrate the effects that this population will have on the Earth’s resources. The model was broken down by country, forecasting food demand while also taking into consideration changing nutritional preferences and income levels.

Over the course of a lifetime, a person has a handful of life-changing moments, including memorable events like a first kiss, relationship endings, and deaths. While you may think about those moments for the rest of your life, though, you probably assume your brain doesn’t experience physical changes as a result.

A new study reveals that the brain actually does undergo alterations as a result of those events. Rockefeller scientist Charles D. Gilbert studied perceptual learning, which is the process of honing your brain to better perceive even the most subtle sights, sounds, and smells. Over time, people become better able to make those perceptions, even though they don’t even realize it. Gilbert wanted to study if the brain could remodel itself in response to life events.

As of October 17, 2018, Canada became only the second nation on the planet to make marijuana legal. While various states in the U.S. have legalized marijuana, it remains to be seen whether doing so on a national basis will result in on overall benefit to society.

Because of the size and scale of Canada's legalization, many around the world will pay attention to how it all works out. Will crime be reduced and tax coffers filled to overflowing, as supporters of legalization contend? Or will legalization of the drug result in greater exposure to its potential ills touted by the drug's detractors, such as long-term memory loss and increased mental illness?

A couple of Arizona State University astronomers recently observed a red dwarf star in the midst of a super flare, or violent outburst, which emitted a greater and more lethal dose of radiation than has ever been picked up from the sun. This event, as observed through the Hubble Telescope, indicates that forms of life on planets surrounding the dwarf star would likely not survive.

What's more, the astronomers contend that super flares of this kind tend to be more prevalent in red dwarfs that haven't been around for very long; their eruptions when young can be anywhere from 100 to 1000 times more powerful than when the stars mature.

Wind turbines have long been recommended as an alternative to traditional energy sources. The goal is to reduce the impact of global warming on the Earth’s resources. However, a new study reveals that heavy reliance on wind power could heat the Earth’s surface by an average of 0.24 degrees Celsius.

Wind already powers about 6.5 percent of the Earth’s energy, but environmentalists are hoping to increase that. The study looked at the impact of relying exclusively on wind turbines for electricity, a scenario that is unlikely to happen. According to the researchers behind the study, wind turbines mix the boundary layer of air, redistributing heat into the atmosphere.
