The development of electronic devices has been rapidly progressing, with a focus on creating smaller and more efficient devices. Two-dimensional (2D) semiconducting materials have emerged as a promising avenue for achieving this goal. These materials offer significant advantages over their traditional bulky counterparts, such as retaining carrier mobility even with reduced thickness. However, the application

Constellations have always required a bit of imagination to decipher. While some, like Leo or Orion, bear a resemblance to their namesakes, others, such as Pegasus or Telescopium, demand a powerful level of imagination to see their intended shapes. Even squinting or tilting our heads doesn’t always make them visible. This same challenge presented itself
For those seeking rapid weight loss or a quick fix before a big event or vacation, crash diets often seem like an appealing option. These types of diets involve drastically reducing calorie intake to 800-1,200 calories per day for a few weeks. Influencers and social media have contributed to their popularity, making them a go-to
Google has recently implemented a restriction on third-party cookies for some users of its Chrome web browser, marking the beginning of its plan to eventually eliminate these files that have raised concerns over user privacy. This move is in line with Google’s announcement in 2020 to do away with cookies, however, the complete elimination of
Spintronic devices have garnered significant interest in recent years for their ability to achieve high-speed processing and low-cost data storage. These devices utilize the spin of electrons to carry and manipulate information. Spin-transfer torque has been a key phenomenon enabling ultrafast and low-power spintronics. However, a promising alternative called spin-orbit torque (SOT) has emerged. This
The distribution of dark matter in the Universe has long intrigued scientists, but recent observations have raised more questions than answers. These observations reveal that dark matter, an elusive substance that exerts a gravitational influence on the Universe, is distributed differently now compared to its early stages after the Big Bang. It appears to be
The chemical industry has long been associated with harmful environmental practices, but efforts are being made to change this perception. Caltech’s Karthish Manthiram and his team have made significant progress in developing a catalyst for producing propylene oxide, a widely used chemical, in a more environmentally friendly manner. This breakthrough could revolutionize the production process
Rice farming in sub-Saharan Africa has seen a significant increase in production over the past decade, resulting in a rise in methane emissions. A team of engineers and atmospheric scientists at Harvard University, together with a colleague from the California Institute of Technology’s Jet Propulsion Laboratory, conducted a study to determine the extent of this
In urban African communities, communication infrastructure has significantly improved, making it easier for people to share information quickly and efficiently. However, the same cannot be said for rural areas, where limited resources and a lack of investment opportunities have resulted in a significant digital divide. In these remote regions, where houses are kilometers apart, residents
Mercury exposure is a well-known and significant health risk, both to humans and animals. The neurotoxic properties of mercury have been extensively studied, but primarily in marine and sea creatures. However, a recent study conducted by Dr. Yulia Pushkar and her research group at Purdue University’s College of Science has shed new light on the
Ultra-intense ultrashort lasers have revolutionized various fields, ranging from basic physics to national security, industry, and healthcare. These lasers have enabled groundbreaking research in strong-field laser physics, laser-driven radiation sources, laser particle acceleration, vacuum quantum electrodynamics, and more. With advancements in laser technology, there has been a significant increase in peak laser power, breaking the
In today’s world, where the issues of waste management and environmental pollution are increasingly critical, researchers at Case Western Reserve University have taken up the challenge of developing innovative solutions. They are currently working on ways to convert waste into fuels and valuable chemicals using energy-efficient processes powered by renewable sources. One particular challenge they
Recent studies have revealed that the microbes living in our guts may play a crucial role in protecting us against excessive weight gain. Researchers at Vanderbilt University, led by biochemist Catherine Shelton, have made significant progress in understanding the relationship between gut bacteria and childhood obesity. Their findings show that exposure to antibiotics at a
Neutron stars, the remnants of massive stars, have always fascinated scientists with their bizarre and extreme nature. These incredibly dense objects are believed to be supported by the quantum pressure of neutrons. However, recent studies suggest that some neutron stars might have an even more peculiar feature – a core made of quarks. This revelation
Africa has been burning for thousands of years, and it shows no signs of stopping. In fact, the continent accounts for over 50% of the total area on Earth that is constantly engulfed in flames. This migrating, hemisphere-hopping wildfire season in Africa is steadily increasing, and it is creating a devastating feedback loop that feeds
