Researchers led by Dr. Jona Kayser at MPZPM report that physical processes in dense cell populations strongly influence the best timing of treatment cycles, with implications for both cancer therapy and antibiotics. Treatment resistance remains one of the central challenges in medicine, and the findings suggest that timing could be adjusted based on how tightly cells pack together rather than on biology alone. The work points to new ways of scheduling therapies to delay or avoid resistance.

Single-celled slime molds, which lack brains yet can solve mazes, optimize networks, and learn simple patterns, are at the center of a growing scientific dispute over how intelligence should be defined. Researchers disagree on whether such abilities reflect genuine cognition or simpler biological processes, a question with implications for neuroscience, philosophy, and artificial intelligence.

Scientists are examining the inner workings of Antarctic fish cells to understand how these animals survive in water barely above freezing. The research aims to reveal the biological mechanisms, likely involving specialized proteins or cellular adaptations, that keep their bodies functioning in conditions that would freeze most fish. The findings could inform broader work on cold tolerance in biology.

Scientists report identifying a so-called third state of existence that sits between life and death, challenging the traditional binary view of biological existence. The claim suggests that some cells or organisms can continue functioning in new ways after an organism has died. The finding is drawing attention for its potential implications in biology, medicine and how scientists define death.

A coaching test on cell biology aimed at candidates preparing for TGT, PGT and other biology teaching exams is circulating widely among Indian exam aspirants.

Students preparing for teacher recruitment exams are sharing and discussing the material as they revise core biology topics.

Researchers report finding a biological 'switch' that could potentially extend lifespans. The discovery centers on AMPK, an ancient enzyme that helps cells survive when energy levels are low. By activating this mechanism, scientists believe it may be possible to slow aging processes, though the finding is at an early stage and human applications remain unproven.

A study published in Nature presents a large-scale mapping of functional signaling landscapes across the human phosphoproteome. The work charts how phosphorylation sites drive cellular signaling, offering a resource for understanding cell regulation and disease mechanisms. Researchers in molecular biology say such maps could help identify new drug targets, though broader reaction and follow-up are still limited.

Researchers have unveiled a paper-thin biohybrid swimming robot driven by a single layer of genetically engineered, living muscle cells that contract in response to light, making the device move with a flapping motion.

Slime molds — single-celled organisms with no brain — can solve mazes, optimize networks and make decisions, reigniting scientific debate over whether 'intelligence' applies without neurons. The discussion touches on how biology should define cognition, with critics arguing the term is being stretched too far and others seeing slime molds as evidence that problem-solving exists well beyond animals.

New commentary calls for a reality check on lab-grown human embryo models, urging scientists to be clearer about what these stem cell-based models can and cannot mimic compared with real embryos. Researchers are weighing how far the models can inform developmental biology and medicine, and where their limits lie, amid growing scientific interest and ethical scrutiny of embryo research.

A new study published in Nature reports that mechanical forces can regulate cell memory, meaning a cell's ability to retain information about its past states.
