Aug 7, 2024 · Many airline passengers naturally worry about flying. But on a worldwide basis, commercial air travel keeps getting safer, according to a new study by MIT researchers. The risk of a fatality from commercial air travel was 1 per every 13.7 million passenger boardings globally in the 2018-2022 period — a significant improvement from 1 per 7.9 ...
Oct 25, 2019 · In this diagram of the new system, air entering from top right passes to one of two chambers (the gray rectangular structures) containing battery electrodes that attract the carbon dioxide. Then the airflow is switched to the other chamber, while the accumulated carbon dioxide in the first chamber is flushed into a separate storage tank (at right).
May 9, 2024 · Researchers developed a potential new treatment for alopecia areata, an autoimmune disorder that causes hair loss. The microneedle patch delivers immune-regulating molecules that can teach T cells not to attack hair follicles, helping hair regrow.
Sep 19, 2017 · Air pollution levels have come down since the 1970s, but smog is being linked with a growing list of diseases, including dementia, obesity, diabetes and even Parkinson’s.
Jun 7, 2022 · MIT researchers demonstrate that over 50 percent of the world’s population would still be exposed to PM2.5 concentrations that exceed new air quality guidelines due to the large natural sources of particulate matter — dust, sea salt, and organics from vegetation — that still exist in the atmosphere when anthropogenic emissions are removed from the air.
Sep 18, 2020 · The list of medical ailments associated with exposure to dirty air includes respiratory diseases, cardiovascular disease and diabetes (SN: 9/19/17). Most of what’s known about the hazards of ...
Mar 26, 2021 · Most people think air conditioners only cool the air in a space, but they also dry the air they’re cooling. Traditional machines use something called an evaporator, a cold coil to pull water out of the air through condensation. The cold coil must be made much colder than the desired temperature in the room in order to collect moisture.
Aug 21, 2024 · They found that, for example, the original model had assumed that a drop in air pressure immediately behind the rotor would rapidly return to normal ambient pressure just a short way downstream. But it turns out, Howland says, that as the thrust force keeps increasing, “that assumption is increasingly inaccurate.”
Jun 30, 2021 · Poor air quality is one of the largest environmental risk factors for premature mortality, heightened by extreme air-quality events that are becoming annual events in parts of the world. LCS networks provide a way forward for other communities to monitor air quality, especially resource-limited regions where air-quality monitoring systems are even more sparse or nonexistent.
