Have you ever wondered why some electronic devices can heat up quickly? A big reason is tiny components called GaN HEMTs. These little transistors can get really hot, especially when there are many of them. Scientists came up with a clever solution: they swapped the silicon carbide base with a singl
You might not think much about the direction of tiny side chains in solar cells, but they play a huge role! These chains, attached to molecules in organic photovoltaics, can either be 'meta' or 'para'. Researchers found that when these chains are in the 'meta' position, they help the cell work bette
In the early 1960s, two brilliant scientists, Eduardo Lissi and Juan Grotewold, kicked off a remarkable journey in chemical kinetics and photochemistry at the University of Buenos Aires' School of Sciences. Politics played a big role in shaping their group's evolution, with members scattering across
Narwal, a company known for its groundbreaking cleaning technology, has been making waves in the home cleaning industry. They've discovered the key to perfect floors: blending innovation with customer convenience. This approach has led to the creation of smart robots that have boosted Narwal's reput
In dietetics, the buzzwords have long been equity, diversity, and inclusion (EDI). While these are worthwhile goals, they might not be enough to tackle the deep-seated issues of racism in the field. This is where racial justice steps in. Unlike EDI, which focuses on creating a level playing field, r
Robert F. Kennedy Jr. is set to take on a major role in the Trump administration, and his focus on toxics is a game-changer. In a previous interview, Kennedy pointed out that Democrats have largely ignored the issue of toxics, and he wants Republicans to step up. This isn't just about politics; it's
Robert F. Kennedy Jr. , a 71-year-old member of a well-known Democratic family, is facing his first confirmation hearing to become the Secretary of Health and Human Services under President Trump. This hearing will take place in front of the Senate Finance Committee. Kennedy has been in the public e
The Bulletin of the Atomic Scientists has moved the Doomsday Clock closer to midnight than ever before, setting it at 89 seconds till midnight. This annual announcement indicates that humanity is closer to destruction due to various threats like climate change, nuclear weapon proliferation, and pand
Identifying those who have passed away can be a critical step in solving mass disasters, wartime incidents, or forensic cases. Forensic anthropologists play a key role by establishing a biological profile of the deceased. This includes figuring out their sex, age, height, ancestral background, and e
Drugs don't always stop cancer cells from growing, but they often mess with their metabolism. Scientists used a high-tech method, called metabolomics, to see how 1, 520 drugs affected 2, 269 potential metabolites in A549 lung cancer cells. Even though only 26% of the drugs slowed down cell growth, a
