Catching Alport syndrome through universal age-3 urine screening

2025-10-07

The most common first diagnosis of Alport syndrome in Japan is during the universal age-3 urine screening. In 60% of these children, the disease had already progressed far enough to qualify for treatment. Therefore, universal early-age urinalysis may be an apt means for both better prognoses and reduced costs of medical care. Alport syndrome is a genetic disease that affects about one in 5,000 people. Patients cannot produce a certain type of collagen which leads to kidney failure, and may also lead to hearing loss and ...

Instructions help you remember something better than emotions or a good night’s sleep

2025-10-07

A good night’s sleep has long been understood to help us consolidate new memories, but we don’t understand how. Associations with negative feelings like fear or stress can improve recall, but intentionally trying to remember can also be effective. But these two mechanisms are very different — one involuntary, one deliberate. Which influences memory most? To investigate, researchers asked participants to remember or forget words, some of which had negative emotional associations. They found that instructions improved recall ...

Yeast proteins reveal the secrets of drought resistance

2025-10-06

Our bodies are made up mostly of water. If this water is removed, our cells cannot survive, even when water is reintroduced. But some organisms can completely dry out yet return to life when rehydrated. A new study in Cell Systems helps explain how organisms can come back from desiccation (the removal of water or moisture) while others fail by looking at the cell’s proteins. In the first survey of its kind, a team of researchers profiled thousands of proteins at once for their ability to survive dehydration and ...
