Did you know that light can influence your brain and mood? Scientists have found that shining infrared light on a specific part of the brain, called the hippocampus, can boost the growth of new brain cells. This part of the brain is linked to mood disorders, and growing new cells there can help redu
In long-term studies where researchers are examining events that happen over time, it's common to find that important factors, or covariates, change over time. The old-school Cox regression model can deal with these changing factors but assumes that their impact on the likelihood of an event is just
Celery, a key player in the vegetable world, has many forms. There's common celery, known for its solid, crisp stalks, celeriac with its fleshy, underground stems, and leaf celery, which has long, hollow stalks. Here's where things get interesting: scientists recently created a detailed map of the c
In 2024, artificial intelligence (AI) showed its power in surprising ways. Scientists used AI and X-rays to read ancient scrolls from Herculaneum, Italy, that were buried by the Mount Vesuvius eruption in 79 AD. These scrolls are so delicate they can't be unrolled, but AI helped decode over 2, 000 c
Imagine a weather satellite that's been retired for a while, just floating in space. Well, an old one from a military program called DMSP-5D2 F14 has broken up into over 50 pieces. Why's this a big deal? This satellite was launched in 1997 and has been orbiting ever since its retirement in 2020. Now
Ever wondered how your body keeps you cool while you exercise? Scientists have been looking into how certain receptors, called α- and β-adrenergic receptors, help regulate sweating, especially when you're working out in the heat. They found that blocking these receptors can affect how much you sweat
Phytoplankton, tiny ocean plants, have a daily rhythm. They produce a lot of carbohydrates and amino acids which bacteria love to eat. These nutrients have daily ups and downs, playing a big role in the ocean's nutrient cycle. Across different ocean areas, like near Antarctica and in the tropics, th
Plants use something called Light-Harvesting Complex II (LHCII) to efficiently capture light for photosynthesis. Scientists have been trying to understand how LHCII does this so well. They use quantum chemistry, molecular dynamics, and statistical mechanics to study the pigment molecules in LHCII. I
Ciprofloxacin, a common antibiotic, is a tough guy that doesn't go away easily. When it ends up in water, it causes big problems for fish and other aquatic creatures. We need to get rid of it to keep our water clean and healthy. Scientists have found a cool way to break it down using tiny things cal
Clean energy is a big deal, and hydrogen is a superstar in this field. One cool way to generate hydrogen is by breaking down urea in water. This happens in a process called urea oxidation reaction (UOR). Scientists have created a special electro-catalyst to make this happen in salty water, similar t
