Novel technique enables air-stable water droplet networks
(Phys.org) —A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research and harvesting water from fog.
Researchers figure out why gold nanoparticles can penetrate cell walls
Cells are very good at protecting their precious contents—and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective ...
3-D printer builds synthetic tissues
A custom-built programmable 3D printer can create materials with several of the properties of living tissues, Oxford University scientists have demonstrated.
Breakthrough in race to create 'bio-batteries'
(Phys.org) —Scientists at the University of East Anglia have made an important breakthrough in the quest to generate clean electricity from bacteria.
Artificial ion channels created using DNA origami
'Endless possibilities' for bio-nanotechnology
Scientists from the University of Leeds have taken a crucial step forward in bio-nanotechnology, a field that uses biology to develop new tools for science, technology and medicine.
Brandeis physicists unlock secrets of the 2-D world and edge closer to artificial cells
Physicist Zvonimir Dogic and his lab are on a roll. Last week, Dogic's research was featured in two of science's most respected journals, Science and Nature.
Artificial membranes on silicon: First synthetic membranes made without solvents described
Artificial membranes mimicking those found in living organisms have many potential applications ranging from detecting bacterial contaminants in food to toxic pollution in the environment to dangerous diseases ...
'Fingerprinting' cell metabolism points toward study of obesity, diabetes
(Phys.org) —Researchers have shown how to use a new imaging platform to map lipid metabolism in living cells, discovering specifically where cholesterol is stored and pointing toward further studies in ...
New imaging approach accurately measures lipid and metabolite distributions in biological samples
To understand how cells converse, scientists at Pacific Northwest National Laboratory and Oregon Health & Science University designed an approach that accurately determines the spatial location of molecules ...
New membrane-synthesis pathways in bacteria discovered
Biologists at the Ruhr-Universität Bochum (RUB) have discovered new mechanisms used by bacteria to manufacture lipids, i.e. fat molecules, for the cell membrane. Those mechanisms are a combination of familiar ...
Protein anchors help keep embryonic development 'just right'
The "Goldilocks effect" in fruit fly embryos may be more intricate than previously thought. It's been known that specific proteins, called histones, must exist within a certain range—if there are too few, ...
The Sheep Genome: Study shows how sheep first separated from goats
Scientists have cracked the genetic code of sheep to reveal how they became a distinct species from goats around four million years ago. The study is the first to pinpoint the genetic differences that make ...
Neanderthal variants in genes involved in lipid catabolism
Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans.
