Tobacco isn't just tobacco. It's a puzzle of scents that change depending on where it's grown. Scientists have been busy figuring out what makes tobacco from different parts of China smell unique. They used a fancy tool called HS-GC-IMS to sniff out 98 different aroma compounds. These include esters
Making the choice to report a loved one's dangerous behavior to authorities is a tough call. It's like being stuck between a rock and a hard place. On one hand, you want to protect society. On the other, you don't want to betray someone you care about. A recent study dug into this dilemma. It looke
On June 30, 1908, a massive explosion rocked the skies over Siberia, flattening over 830 square miles of forest. This event, known as the Tunguska event, remains the largest asteroid-related blast in recorded history. Today, June 30 is celebrated as International Asteroid Day to raise awareness abou
Scientists are exploring a fascinating and controversial field: creating human DNA from scratch. This isn't about tweaking existing DNA; it's about constructing it entirely in labs. The aim is to understand DNA better and find innovative treatments for diseases like heart failure, aging, and infecti
Blue Origin is getting closer to sending its New Glenn rocket on its second trip to space. This time, the rocket might be heading to Mars. The company has already tested the second stage of the rocket in April. Right now, the first stage is being prepped at their Florida base. The second launch was
In the vast expanse of space, a dead satellite named Relay 2 made a surprising comeback. Astronomers in Australia detected a powerful radio signal in mid-June that initially sparked excitement. They thought they had stumbled upon an unknown object near Earth. However, the source of the signal turned
A researcher decided to scan her own brain 26 times to learn more about how pregnancy affects the brain. This is something that hasn't been studied much before. The researcher, who studies learning and memory, had her brain scanned before, during, and after her pregnancy. She wanted to see if there
Inside the brain, there's a sneaky fight happening. Glioblastoma, a tough type of brain cancer, is always finding ways to survive. Scientists have spotted a clever trick it uses. A tiny helper inside cells, called SH3GLB1, is part of this trick. It helps cells clean up and recycle their own parts. T
Plants have a clever way of managing their DNA. They use special proteins called REM transcription factors and a helper protein named GDE1 to direct tiny RNA molecules to specific spots on the DNA. These RNA molecules act like guides, helping to add chemical tags called methyl groups to the DNA. Thi
Japan's space program reached a milestone on June 28 with the final launch of its H-2A rocket. This event marked the end of an era for a rocket that had been a reliable workhorse for the country's space missions. The H-2A rocket lifted off from the Tanegashima Space Center, successfully deploying t
