On your first day on vacation in a new city, you’ll explore a variety of places. While your memories of these places (such as a beautiful garden on a quiet side street) may seem indelible, it may take days before you develop enough of an intuition about the area to guide a new tourist to…
Menstruation is a natural phenomenon that occurs in all women of reproductive age. It refers to the monthly bleeding that occurs when a woman’s uterine lining sheds, but it also involves many hormonal fluctuations that cause different symptoms before and during menstruation. When symptoms occur before menstruation, it’s called premenstrual syndrome (PMS) and, according to…
Everyone feels tired and fatigued after a long journey, but when it comes to traveling across multiple time zones, the fatigue can increase significantly. This is due to a phenomenon called jet lag, which occurs when your body clock, or circadian rhythm, is out of sync with the new time zone. Interestingly, studies and experts…
In many industrial processes, a common way to separate gases, liquids, or ions is to use heat to purify the mixture, taking advantage of slight differences in boiling points. These thermal processes account for about 10 percent of U.S. energy use. MIT chemical engineer Zachary Smith hopes to reduce costs and carbon emissions by replacing…
Many people around the world live in energy poverty, spending at least 8 percent of their annual household income on energy. Solving the problem won’t be easy, but experiments by MIT researchers show that providing people with better data about their energy use and educating them on the issue could significantly reduce consumption and costs….
Supermassive black holes have riveted astronomers for years, first with their sudden disappearances, then their erratic spinning behavior. The black hole in question has a mass of 1ES 1927+654, about 1 million times that of the Sun, and resides in a galaxy 270 million light-years away. In 2018, astronomers at MIT and elsewhere observed the…
Reviewed by Lexie Corner on January 2, 2025 Scientists at the Hong Kong University of Science and Technology have developed a new deep ultraviolet (UVC) microLED display array for lithography, marking a major advance in semiconductor technology. The research was published in the journal Nature Photonics . Electroluminescence (EL) imaging demonstrates that devices of various sizes, even…
Vijay Gadepally, a senior research scientist at MIT Lincoln Laboratory , leads several projects at the Lincoln Laboratory Supercomputing Center (LLSC) that improve the efficiency of computing platforms and the artificial intelligence systems that run on them. Here, Gadepally discusses the increasing use of generative AI in everyday tools, its potential impact on the environment, and some ways…
Ballistic weapons, whether launched from a cannon, long-range missile, or aircraft, go through a deceleration phase before reaching a “steady-state flight” state, at which point the missile can automatically detect and identify its target. To ensure accuracy, extensive testing must be conducted early in development to measure the rotation rate and sweep angle of the…
A study led by UCLA Health’s Jonsson Comprehensive Cancer Center published in JAMA Network Open found that nearly half of patients classified as non-metastatic using traditional imaging were found to have metastatic disease when evaluated with advanced PSMA-PET (prostate-specific membrane antigen emission tomography) imaging, highlighting the limitations of traditional imaging in accurately assessing the spread of cancer. …
