- Holographic microscopy: Peering into living cells -- with neither dye nor fluophore Holographic microscopy: Peering into living cells -- with neither dye nor fluophore
Thanks to holographic microscopy, two young scientists have developed a device that can create 3-D images of living cells, almost in real time, and track their reaction to various stimuli without the use of contrast dyes or fluorophores.
- Colon cancer exhibits a corresponding epigenetic pattern in mice and humans Colon cancer exhibits a corresponding epigenetic pattern in mice and humans
The epigenetic investigation of mice can as a result contribute to early diagnosis of cancer in humans.
- Immune systems of healthy adults 'remember' germs to which they've never been exposed Immune systems of healthy adults 'remember' germs to which they've never been exposed
It's established dogma that the immune system develops a "memory" of a microbial pathogen, with a correspondingly enhanced readiness to combat that microbe, only upon exposure to it -- or to its components though a vaccine. But a discovery [...]
- 'Zombie' cells may outperform live ones as catalysts and conductors 'Zombie' cells may outperform live ones as catalysts and conductors
A simple technique uses silica to coat a living cell both inside and outside. The process forms a near-perfect replica of the cell's structure, down to the tiniest organelle. The resulting model, heated, creates nature-sculpted nanotools wi [...]

Has a loss of intestinal bacteria caused our immune systems to go haywire? Moises Velasquez-Manoff lays out the hygiene hypothesis.
- Glacier ‘Mice’ Offer a Micro Habitat Glacier ‘Mice’ Offer a Micro Habitat
Scientists have found micro-organisms sheltering inside glacier mice — clumps of debris, akin to dust bunnies, that develop a protective layer of moss over time.
