Sea lice are a big problem for the salmon industry in Chile. These tiny creatures go through different stages. In one stage, they can sense their host and start the parasitic phase. This is where things get interesting. Environmental factors like temperature and salinity can change how sea lice beha
The path to substance use disorders is never straightforward. It's a mix of nature and nurture. Genes play a role, and so do tough times in childhood. But how these pieces fit together is still a mystery. It's like trying to solve a puzzle with missing pieces. The idea that genes alone cause addic
The world of bacteria is full of surprises. One such surprise comes from the tiny changes that can happen inside a superbug. These changes can make the bug more or less dangerous. This is what happened with a specific type of Klebsiella pneumoniae. This bacterium is known for being tough to treat wi
The world is warming up. This is a fact. And it's affecting our food. Rice is a staple for many. But it's sensitive to heat. Too much heat can ruin the crop. This means less rice and poorer quality. But there's hope. Scientists have found a single gene. This gene helps rice handle the heat. It's a b
Living in caves, the stage-dependent cave frog, Oreolalax rhodostigmatus, has a unique way of life. It is a fascinating example of how animals adapt to their surroundings. This frog has a two-phase life cycle. As a tadpole, it has traits that help it survive in the dark caves. After it grows int
The CEO of General Motors, Mary Barra, started her quarterly letter to investors with a nod to President Trump. She thanked him for his backing of the U. S. auto industry. However, she later revealed a significant issue: the company expects to face a financial hit of $4 billion to $5 billion due to
The Eurasian common shrew, Sorex araneus, is a small mammal that has a unique way of dealing with winter. Instead of hibernating or migrating, it shrinks its brain, skull, and most organs. Then, come spring, it grows back to its original size. This ability to change brain size is something that scie
Temperature plays a significant role in how our genes function. This is especially true for a specific spot in the PDGFRβ gene, where four different changes have been found. These changes, known as p. Asn666Lys, p. Asn666Tyr, p. Asn666Ser, and p. Asn666His, lead to a variety of health issues. These
Nile tilapia, a type of fish, can change sex based on water temperature. This might sound strange, but it's a real phenomenon called temperature-dependent sex reversal (TSR). Scientists have been trying to figure out how this happens at the molecular level. It's not just about the fish changing sex;
The liver of triploid rainbow trout faces unique challenges in low-oxygen waters. To understand how these fish cope, researchers dug into the world of tiny gene regulators called miRNAs. They found 45 miRNAs that change their activity when oxygen levels drop. These miRNAs don't work alone. They team
