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 ...
'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.
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.
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.
Pocket test measures 50 things in a drop of blood

Nanoparticles that look, act like cells
(Phys.org)—By cloaking nanoparticles in the membranes of white blood cells, scientists at The Methodist Hospital Research Institute may have found a way to prevent the body from recognizing and destroying ...
Conversion from bad fat to good fat
Scientists from ETH Zurich in Switzerland have shown for the first time that brown and white fat cells in a living organism can be converted from one cell type to the other. Their work, using mice as a model organism, provides ...
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.
Direct 'writing' of artificial cell membranes on graphene
Graphene emerges as a versatile new surface to assemble model cell membranes mimicking those in the human body, with potential for applications in sensors for understanding biological processes, disease detection ...
A 'warhead' molecule to hunt down deadly bacteria
Targeting deadly, drug-resistant bacteria poses a serious challenge to researchers looking for antibiotics that can kill pathogens without causing collateral damage in human cells. A team of Boston College ...
New system to improve DNA sequencing
(Phys.org) —A sensing system developed at Cambridge is being commercialised in the UK for use in rapid, low-cost DNA sequencing, which would make the prediction and diagnosis of disease more efficient, ...
