Epigenetic differences in Andean highlanders (English, Level A1)

People live in the high Andes.
Life there has low oxygen and cold.
Scientists looked at DNA in people.
They studied two Indigenous groups.
One group lives high and one low.
They found different DNA signals.
These signals can change gene activity.
Changes may help with blood and arteries.

Alternative splicing linked to mammal lifespan

A study in Nature Communications compared alternative splicing across 26 mammal species (lifespans 2.2–37 years) and found splicing patterns better predict maximum lifespan than gene activity; the brain shows many lifespan-linked events controlled by RNA-binding proteins.

Tofersen slows a rare form of ALS

A long-term study shows that tofersen, a drug for a rare genetic form of ALS, can slow disease progression and help some people improve. The trial followed participants for several years and recorded benefits and side effects.

Gene linked to dog ear length discovered

Researchers compared DNA from more than 3,000 canines and found a region near the gene MSRB3 that helps explain ear shape and ear length. The finding may help future disease mapping and breeding tests.

Study: Many people who die by suicide may not have depression

A genetic study from the University of Utah found many people who die by suicide did not have depression or documented suicidal thoughts. Researchers say that screening only for depression may miss some at-risk people.
