How a broken DNA repair tool accelerates aging

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal metabolic processes or external stressors such as radiation or chemical substances. To counteract this, ...

One of Earth's most abundant organisms is surprisingly fragile

A group of ocean bacteria long considered perfectly adapted to life in nutrient-poor waters may be more vulnerable to environmental change than scientists realized. The bacteria, known as SAR11, dominate surface seawater ...

Bacterial 'brains' operate on the brink of order and disorder

The sensory proteins that control the motion of bacteria constantly fluctuate. AMOLF researchers, together with international collaborators from ETH Zurich and University of Utah, found out that these proteins can jointly ...

Crosstalk inside cells helps pathogens evade drugs, study finds

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how these mechanisms drive ...

Researchers confirm new Rickettsia species found in dogs

Researchers from North Carolina State University have confirmed that a species of Rickettsia first seen in dogs in 2018 is a new species of bacteria. The new species, dubbed Rickettsia finnyi, is associated with symptoms ...

Toxoplasmosis: How a deadly parasite infects its host cells

Researchers at LMU in collaboration with the European Molecular Biology Laboratory (EMBL) in Heidelberg have discovered how the parasite Toxoplasma gondii builds a specialized structure that allows it to move and invade host ...

Shapeshifting gates guard the cell nucleus, challenging old ideas

An international study led by the University of Basel has discovered that nuclear pore complexes—tiny gateways in the nuclear membrane—are not rigid or gel-like as once thought. Their interiors are dynamically organized, ...

Quantitative ATP imaging can measure cellular energy in real time

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, have developed a method for quantitative imaging of ATP levels inside living cells. The study, published in Nature Communications, introduces ...
