The conversion of light into electricity is a fundamental process that underpins the function of solar cells. In recent years, there has been increasing interest in the study of the bulk photovoltaic effect, a phenomenon that involves a single material and has the potential to greatly improve the efficiency of solar cells. A team of

Extreme environmental events are a growing concern as climate change continues to exert its impact on both terrestrial and marine ecosystems. Heat waves, particularly in the ocean, are proven to be significant contributors to this trend. In the summer of 2021, an unprecedented marine heat wave occurred in the East Sea (Sea of Japan, northwest
Researchers at Columbia University and the Max Planck for the Structure and Dynamics of Matter have made an exciting discovery that could revolutionize nonlinear optics. By pairing laser light with crystal lattice vibrations, they have found a way to enhance the nonlinear optical properties of a layered 2D material. This research, published in the journal
Japan’s space exploration efforts have taken a significant step forward as its SLIM space probe successfully entered the Moon’s orbit. Nicknamed the “Moon Sniper,” this ambitious mission aims to achieve Japan’s first-ever successful lunar landing, which is expected to take place next month. The achievement would place Japan among an elite group of countries that
Infertility is often mistakenly seen as a problem exclusive to women, but statistics show that one in every three in vitro fertilization (IVF) cycles in Australia is due to male infertility. It is important to note that regardless of the underlying cause, men experiencing infertility often suffer from symptoms of depression, anxiety, and general psychological
In a shocking turn of events, Daihatsu, a subsidiary of Toyota Motor Corp., has decided to halt production in all four of its factories in Japan. This decision comes as transport ministry officials launch an investigation into improper safety tests for certifications. The suspension of production follows Daihatsu’s announcement last week that it was temporarily
Recent research has revealed that maintaining physical activity levels throughout young adulthood is crucial for preventing hypertension, also known as high blood pressure. This is particularly important as hypertension is a serious condition that affects billions of people worldwide and is associated with an increased risk of heart attack, stroke, and even dementia in later
A recent study conducted by an international team of scientists, led by Dr. Rebecca Hamilton at the University of Sydney, challenges the previous scientific consensus on the dominant landscape during the Last Glacial Maximum in South East Asia. Contrary to the belief that the region was predominantly dry savannah, the team discovered a mosaic of
The joint US-Canadian military monitoring agency, North American Aerospace Defense Command (NORAD), holds a long-standing Christmas tradition of tracking Santa Claus’s whereabouts during his global gift-giving mission. The tradition began in 1955 when a Colorado newspaper mistakenly printed a phone number leading to NORAD’s military defense center instead of Santa’s hotline. To avoid disappointing children,
Artificial sweeteners have become increasingly popular in recent years, with many people choosing them as a healthier alternative to sugar. However, could these sweetened drinks be making us feel more anxious? A recent study conducted in 2022 suggests that the artificial sweetener aspartame may have an impact on anxiety levels. This article delves into the
The quest for space dominance has ignited a new “space race” between the United States and China, with Lagrange points emerging as a critical battleground. These points, named after astronomer Joseph-Louis Lagrange, are locations in interplanetary space where the gravitational pull of two celestial bodies creates a balance with the centripetal force required for a
NASA’s Langley Research Center in Hampton, Virginia has recently achieved a significant milestone in the development of self-flying air taxis. Through a series of tests, researchers successfully flew multiple drones beyond visual line of sight without a visual observer. This breakthrough is a crucial step toward advancing the automation and safety systems required for autonomous
Our planet, Earth, is filled with extraordinary phenomena that constantly remind us of its distinctiveness. Surprisingly, these reminders are not limited to far-off locations; they can even occur in our neighboring planet, Mars. Mars, like Earth, experiences eclipses caused by its moons. However, the eclipses on Mars, as observed by NASA rovers Opportunity, Curiosity, and
The rise of artificial intelligence (AI) has brought both excitement and concern to the world of art. While AI can create impressive imitations of artists’ styles, it often does so without giving credit or compensation to the original creators. This issue has led artists, such as US illustrator Paloma McClain, to take action. McClain turned
Excessive worry about one’s health, commonly referred to as illness anxiety disorder (IAD), has been found to have a significant impact on life expectancy, according to a recent study conducted in Sweden. Although it may seem counterintuitive that hypochondriacs, who constantly worry about their health despite being medically healthy, have shorter lifespans, the findings of
