Search the life sciences
Results tuned to biology
4Biology is a focused search engine built for biology students, researchers, educators, and lab managers. We combine multiple indexes, curated sources, and AI tools to surface publications, protocols, datasets, suppliers, and learning resources that matter to life scientists. Use the site to save time, find specialized resources, and get context-specific search results not optimized for general web traffic. Part of the 4SEARCH network of topic specific search engines.

Scientists uncover evolutionary history of gene associated with
11+ hour, 42+ min ago (402+ words) Variants in the human gene PSPH may help explain why some people develop severe neurological disorders linked to inadequate production of the amino acid L-serine....
A giant bleb for cell-kind: artificial cells reveal how living cells take shape

Time-lapse confocal images of a liposome showing bleb formation and expansion. view more A system of artificial cells to study cell morphogenesis As Miyazaki explains, "by reconstructing membrane morphogenesis from purified proteins, we showed that local interactions within the…...
Noisy bubbles impede ultrasound-enhanced chemical reactions, sonochemistry
13+ hour, 53+ min ago (458+ words) Ultrasound can make chemistry happen inside a liquid by creating microscopic bubbles that collapse with extraordinary force. Yet a new computational study suggests that turning up the sound does not always make these reactions more powerful....
Artificial cells reveal how living cells take shape through giant blebs
15+ hour, 48+ min ago (468+ words) Researchers in Japan have reconstructed a key aspect of cellular behavior inside artificial cells, showing that a network of actin and myosin proteins can produce large-scale changes in cell shape—and even establish a front and rear—without the biochemical…...
Plant ULTRAPETALA1 Balances Trithorax and Polycomb Signals to Fine-Tune
20+ hour, 32+ min ago (447+ words) Scientists have uncovered a surprising molecular double life at the heart of plant development. A protein long associated with activating genes has now been shown to directly stimulate a major gene-silencing machine, revealing how plants may switch between opposing chromatin…...
These Beautiful Flowers Can Paralyze You, but Their Chemistry Could Save Lives
1+ day, 12+ hour ago (836+ words) Researchers take the first steps toward recreating powerful chemicals derived from plants in the laboratory. Wolfsbane and larkspur can cause neurotoxicity and paralysis at extremely low doses, yet their chemistry has also been used against pain, malaria, cancer, and pests....
HMGA1 Promotes Bone-Like Transformation of Vascular Muscle Cells in Kidney
1+ day, 9+ hour ago (501+ words) Chronic kidney disease is often described as a disorder of filtration, but its consequences extend far beyond the kidneys. One of its most dangerous complications is vascular calcification, a process in which the walls of arteries gradually accumulate mineral deposits…...
New study reveals aging unfolds at different rates across individual cells
1+ day, 11+ hour ago (435+ words) Aging may be far less synchronized than scientists have traditionally assumed. A new study published in Nature Communications reports that cells of the same chronological age can follow dramatically different biological aging trajectories, even when they are located beside one…...
Smithsonian scientists untangle Hawaiian honeycreeper evolutionary family
1+ day, 14+ hour ago (435+ words) Smithsonian researchers have reconstructed the most comprehensive evolutionary map yet of Hawaii’s honeycreepers, a spectacular group of birds whose rapid diversification produced more than 60 species from a single ancestral population. The study, published in the Proceedings of the National Academy…...
Scientists Reveal How Centromeres and Inner Kinetochores Work
1+ day, 15+ hour ago (468+ words) A new review in Nature Reviews Molecular Cell Biology is bringing the hidden architecture of chromosome inheritance into sharper focus, examining how centromeres and inner kinetochores work together to guide chromosomes through cell division. The study, authored by R. R. Brown, P. J. Huis…...
