A tiny biological fuel cell, the smallest of its kind (0.3 microliters), has been built by researchers at Carnegie Mellon University (CMU), powered by
Researchers have used cutting-edge stem cell technology to correct a genetic defect present in a rare blinding disorder, another step on a promising path that may one day lead to therapies to reverse blindness caused by common retinal diseases.
The quest for better ways of encapsulating medicine so that it can reach diseased parts of the body has led scientists to harness -- for the first time -- living human cells to produce natural capsules with channels for releasing drugs and diagnostic agents.
Scientists have discovered a new type of cell in the immune system. The new cell type, a kind of white blood cell, belongs to a family of T-cells that play a critical role in protection against infectious disease. Their findings could ultimately lead to the development of novel drugs that strengthen the immune response against particular types of infectious organisms.
In the search for superconductors, finding ways to compress hydrogen into a metal has been a point of focus ever since scientists predicted many years ago that electricity would flow, uninhibited, through such a material.
Three molecules thick, or two, or one: how does an extremely thin layer of trapped liquid behave when we make it even thinner? Measurements made using the atomic force microscope show that the forces of friction increase with each step. Liquids begin to behave more like a gel, according to new research.
Millions of people with knee injuries could benefit from a new type of stem cell bandage treatment if clinical trials are successful. The world

Dec. 2 - A team of scientists has demonstrated that a coordinated group of pre-programmed, autonomous robots can do the job of building workers, constructing a six meter high tower without any human intervention. Architects say this new technology paves the way for new methods of engineering buildings of the future. Georgina Cooper reports.
Watching things disappear is an amazing experience. But making items vanish is not the reason scientists work to create invisibility cloaks. Rather, the magic-like tricks are attractive demonstrations of the fantastic capabilities that new optical theories and nanotechnology construction methods now enable.
Research shows that a walk in the park is more than just a nice way to spend an afternoon. It
(PhysOrg.com) -- A new study in the Proceedings of the National Academy of Sciences shows that bacteria is capable of growing under gravity more than 400,000 times that of Earth and gives evidence that the theory of panspermia could be possible.
(PhysOrg.com) -- When atoms combine to form compounds, they must follow certain bonding and valence rules. For this reason, many compounds simply cannot exist. But there are some compounds that, although they follow the bonding and valence rules, still are thought to not exist because they have unstable structures. Scientists call these compounds "impossible compounds." Nevertheless, some of these impossible compounds have actually been fabricated (for example, single sheets of graphene were once considered impossible compounds). In a new study, scientists have synthesized another one of these impossible compounds -- periodic mesoporous hydridosilica -- which can transform into a photoluminescent material at high temperatures.
(PhysOrg.com) -- Researchers at MIT have found a way to make significant improvements to the power-conversion efficiency of solar cells by enlisting the services of tiny viruses to perform detailed assembly work at the microscopic level.
