Alzheimer's disease is a big deal. It's a condition where the brain slowly breaks down. It's one of the toughest medical puzzles out there. Scientists have found that certain gene mutations can lead to early-onset Alzheimer's. These mutations are in the presenilin 1 and 2 (PSEN1 and PSEN2) and the a
Tuberculosis, or TB, is a sneaky disease. It can hide in the body, making it tough to spot. Doctors often use sputum cultures to find TB bacteria. But sometimes, these tests come up empty, even when TB is present. This is where things get tricky. New, super-sensitive tests like GeneXpert MTB/RIF Ult
Type 2 diabetes is a growing concern worldwide. It's a complex condition influenced by genetics and lifestyle. Genes play a significant role in how the body handles fat. This is known as genetic predisposition to adiposity. It's a fancy term for the tendency to store fat, even if someone is not o
Atherosclerosis is a condition where fatty deposits build up in the arteries. This can lead to heart disease and stroke. It is well known that disturbed blood flow plays a big role in this process. But what if there is more to the story? What if certain genes also play a part? In recent research, s
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.
