Keeping a cell's nucleolus compact may be key to fighting aging

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to Weill Cornell Medicine investigators. The findings were elucidated in yeast, a model ...

Fuji apple study finds genetic mechanisms behind high-yield trees

Apples rank among the world's most valuable fruit crops, with production spanning more than 100 countries. Some apple trees naturally develop into what farmers call "spur-type" varieties—compact trees that are more productive ...

Hidden pocket in human bitter taste receptor discovered

A new study describes an exciting discovery that changes the way we understand human bitter taste receptors. The research has revealed a hidden "pocket" inside one of the body's bitter taste receptors, called TAS2R14.

Decoding the cellular basis of floral fragrance

Floral fragrances are nature's allure, enticing pollinators and helping plants adapt to environmental challenges. These scents, primarily generated in petals, consist of complex compounds such as terpenoids and benzenoids/phenylpropanoids, ...

Molecular morphers: DNA-powered gels shape-shift on command

Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These "gel automata," measuring just centimeters, can grow or shrink, transforming from one letter ...

New tools filter noise from evolution data

While rates of evolution have appeared to accelerate over short time periods, new analysis suggests that statistical noise is affecting the data patterns. A professor at the University of Tennessee, Knoxville, and his colleague ...

tRNAs help some mRNAs get lost in translation

Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein ...

Study reveals RNA's unknown role in DNA damage repair

A multi-institutional team of researchers, led by Georgia Tech's Francesca Storici, has discovered a previously unknown role for RNA. Their insights could lead to improved treatments for diseases like cancer and neurodegenerative ...

AI tool can engineer 'better, faster, stronger' proteins

Nature is adept at designing proteins. Scientists are even better. But artificial intelligence holds the promise of improving proteins many times over. Medical applications for such "designer proteins" range from creating ...
