According to the Union of Concerned Scientists, there are nearly 2,800 working satellites in space. We depend on these devices for technology we use every day, such as video calls, online maps, satellite TV, and weather tracking. Scientists use them to study space and learn more about our planet.
But there are many other satellites in orbit that are no longer working. They’re among the objects cluttering up space. Some of these eventually fall back toward Earth, either landing or burning up in the atmosphere. But much of this space junk circles Earth for decades.
Orbital debris, a type of space junk, is any human-made object that has stopped working but continues to float around the Earth. This includes abandoned satellites and pieces of spacecraft, such as rocket stages.
Space junk also includes fragments of objects. These occur when satellites collide with things. They also result from an object crashing into an old rocket stage that still contains fuel, causing an explosion.
Heather Cowardin works at NASA. She says the United States is tracking more than 23,000 pieces of space debris. These tiny fragments can damage working satellites, which can affect research in space. That’s why cleanup efforts are so important.

Is alkaline water really better for you?
Despite the claims, there’s no evidence that water marketed as alkaline is better for your health than tap water. “It’s all about marketing,” said Tanis Fenton, a registered dietitian and epidemiologist at Cumming School of Medicine at the University of Calgary. “There is no science to back it up.”
The pH scale indicates whether a liquid is more acidic (lower pH) or alkaline (higher pH). Pure water has a neutral pH of 7, while tap water has some natural variation depending on its mineral content. Most bottled waters are slightly acidic, and sodas and juices are even more so. Bottled waters marketed as being alkaline typically claim to have a pH between 8 and 10. Some are from springs or artesian wells and are naturally alkaline because of dissolved minerals. Others are made with an ionizing process, and water ionizing machines are also marketed for home use.
Alkaline water companies make vague claims that it will “energize” and “detoxify” the body and lead to “superior hydration.” And some claim that ionized water can prevent everything from headaches to cancer. Nevertheless, there’s no evidence that drinking water with a higher pH can change the pH of your body, or even that this outcome would provide benefits. Blood is tightly regulated at around pH 7.4, while the stomach, which secretes hydrochloric acid to digest proteins and kill food-borne pathogens, is very acidic, with a pH of 1.5 to 3.5. If you drink water that is slightly alkaline, Dr. Fenton said, the hydrochloric acid in the stomach quickly neutralizes it before it’s absorbed into the blood.
Several small studies funded by companies that sell alkaline water suggest that it could improve hydration in athletes, but any potential benefits were modest, and an easier way to improve hydration is just to drink more water. And a 2016 review of research by Dr. Fenton and a colleague found no evidence that alkaline water or an alkaline diet could treat or prevent cancer.
A study published last year found that adopting a plantbased diet and drinking alkaline water worked as well as medications to alleviate the symptoms of laryngopharyngeal reflux, a severe form of acid reflux in which stomach acid travels all the way up to the throat. “I think that it can be a helpful tool for patients to help with their symptoms while they’re transitioning to a more plant-based diet,” said Dr. Craig Zalvan, the study’s lead author and a laryngologist at Phelps Hospital in Sleepy Hollow, N.Y. But he believes that most of the improvement in his patients comes from dietary changes rather than alkaline water. Once symptoms improve, he says there’s no need to keep drinking alkaline water.

A host of social, environmental and psychological factors could play a role in the link between a neighborhood’s socioeconomic status and the risk of its inhabitants developing dementia. For example, poorer areas have lower access to healthcare and less green space, which has been shown to protect older adults from dementia risk, according to recent studies. Air pollution, which was tied to cognitive decline in a study by Chinese researchers, tends to be worse in poorer neighborhoods. Multiple studies have linked a healthy diet with improved cognitive function, but healthy foods are more expensive in many regions.
Crime and social disorder, which impact a person’s perception of safety and community cohesion, may also increase dementia risk for residents in lower socioeconomic status areas. Chronic stress due to structural disadvantages, discrimination and economic adversity will wear down a person’s brain, as high cortisol — the hormone that correlates with stress — produces neurotoxic effects, according to multiple studies. “With healthy lifestyle habits a key factor in reducing or delaying your risk of developing dementia, it is important for everyone to have access to local facilities such as gyms and public pools, green spaces and health care, but unfortunately that is not always the case,” said Professor Matthew Pase.
