After a heart attack, the heart needs new blood vessels to heal and work better. But the low-oxygen environment after a heart attack makes it hard for these new vessels to form. ATF4 is a protein that might help with this process. Scientists did some experiments to see how ATF4 works. They used cel
Tomatoes, like many plants, have a fascinating way of blooming. It's not just one gene that makes this happen. Instead, it's a team of genes working together. Scientists dove into this topic. They wanted to understand how three important genes in tomatoes help them flower. First, they looked at the
Tristan Rogers, a familiar face on daytime television, has passed away at the age of 79. His battle with lung cancer was brief, as he was diagnosed just one month before his death. The news of his passing has left many fans and colleagues heartbroken, including Finola Hughes, who shared a heartfelt
Tech in schools has always sparked strong feelings. Some see it as a threat. Others see it as a tool to help students learn better. This isn't new. People have been worried about tech in schools for a long time. Back in the 1970s, teachers were scared of calculators. They thought these small device
The moon is back on the agenda for both the US and China. But before astronauts can set up camp, there's a big question: how will they survive up there? Living in space is tough. You can't just pop to the shop for supplies. So, scientists are looking at ways to grow food and recycle resources using
In Thailand, a study looked at how pesticides might affect babies' brain development. The focus was on farmworkers who were pregnant. Researchers checked their urine for pesticide traces and studied the genes in their placentas. They also tested the babies' behavior at five weeks old. The study fou
Vinay Prasad is back at the Food and Drug Administration (FDA), picking up where he left off just two weeks ago. He's in charge of vaccines, gene therapies, and blood products again. The FDA asked him to come back, but it's not clear if he'll keep his other big job as the agency's top medical and sc
Small changes in water temperature can have big effects on harmful algae. Alexandrium pacificum is a type of algae that makes toxins harmful to sea life and people. These toxins can build up in shellfish, causing poisoning when eaten. Recent studies show that as water gets warmer, these algae change
A team of engineers has come up with a plan for a massive spaceship that could carry thousands of people on a one-way trip to Alpha Centauri, the nearest star system to ours. This spaceship, named Chrysalis, is designed to travel an incredible distance of 25 trillion miles (40 trillion kilometers) i
Cancer is a shape-shifter. It doesn't stay the same. Neither do the genes that fuel it. One such gene, HER2, is well-known for its part in breast and stomach cancers. But it's not just limited to these. Around 3. 5% of all solid tumors have HER2 mutations. This makes it a potential target for treatm
