A new cyan fluorescent protein will make cellular imaging more sensitive

Scientists have designed a molecule which emits turquoise light more efficiently than seen before in living cells. This improves the sensitivity of imaging of biological processes inside a living cell.

Cellular aging increases risk of heart attack and early death

Every cell in the body has chromosomes with so-called telomeres, which are shortened over time and also through lifestyle choices such as smoking and obesity. Researchers have long speculated that the shortening of telomeres increases the risk of heart attack and early death.

Multi-parametric cellular analysis

Flow cytometry offers several advantages over other techniques by enabling multi-parametric, individual cell analysis. MaryAnn Labant reports

Spying on a cellular director

The cellular machine called the spliceosome snips out unwanted stretches of genetic material and joins the remaining pieces to fashion a template for protein production.

Real-time view of cellular phenomena

Scientists have recorded the first microscopic images showing the deadly effects of AMPs, most of which kill by poking holes in bacterial cell membranes.

Shifting cellular energy metabolism

Researchers has identified several FDA-approved agents, including an over-the-counter anti-nausea drug, that can shift cellular energy metabolism processes in animals.

Cellular communication in the cancer microenvironment

A team of scientists lend new insight into the mechanism by which tumour-associated macrophages promote malignant progression.

Understanding cellular synthetic circuits

As scientists work toward making genetically altered bacteria create living "circuits" to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way.

New cellular targets for HIV drug development

Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research.

Cellular split personality

Researchers have discovered that cells which normally support nerve cell survival also play an active and major role in the death of neurons in the eye.

Uniform and precise cooling of cellular samples

The mechanically refrigerated Bio-Cool provides a reliable, safe and quiet alternative to controlled-rate freezers that utilise liquid nitrogen as the refrigerant.

Key protein in cellular respiration discovered

Researchers have discovered a new function for a protein in the mitochondrion that plays a key part in cell respiration.

Cellular communication via amino acids

Researchers have found evidence of cell-to-cell communication by amino acids rather than by known protein signaling agents such as growth factors or cytokines.

Altering cellular form and function

Harvard Apparatus’ family of cell modification and re-engineering products are utilised when the introduction or withdrawal of molecules.

Cellular eavesdropping made easy

It is much harder to keep up with a conversation in a crowded bar than in a quiet little café, but scientists wishing to eavesdrop on cells can now do so over the laboratory equivalent of a noisy room. A new method devised by scientists at the European Molecular Biology Laboratory in collaboration with the German Cancer Research Centre, both in Heidelberg, Germany, provides a new approach for studying the proteins cells release to communicate with each other, react to changes, or even to help them move.

Cellular process that fights herpes

Scientists have discovered a new way for our immune system to combat the elusive virus responsible for cold sores: Type 1 herpes simplex.

Cellular double jeopardy

Cells have two chances to fix the same mistake in their protein-making process instead of just one - a so-called proofreading step - that had previously been identified, according to new research.

Cellular transport insight

Scientists have now discovered how molecular motors transport cargoes in cells. Two competing teams of motors pull in opposite directions, like in a tug-of-war contest.
