Biodegradable nanofiber microspheres show promise as a means of transporting cells to cart...

Cartilage wounds can be very difficult to treat. While they may eventually heal on their own, the resulting tissue often won't take the same form – or allow for the same function – as the original. Cartilage injuries are often treated with a process known as ACI (autologous chondrocyte implantation), in which a patient's own cells are injected at the wound site to form new tissue. The procedure doesn't always work, as the cells are just injected loosely, with no carrier to transport them or help them get established. Now, however, a scientist from the University of Michigan has developed a technique in which cells are delivered to wounds via injectable nanofiber spheres, and the results are said to be very promising.  Read More

A new discovery by U-M researchers could see energy from the sun harnessed without solar c...

It has long been thought that, even though light has electric and magnetic components, the effects of the magnetic field are so weak that they could effectively be ignored. Now researchers at the University of Michigan (U-M) have discovered that under the right conditions, a light field can generate magnetic effects that are 100 million times stronger than previously expected. The researchers say the discovery paves the way for the creation of an "optical battery" that could harness power from the sun without the use of solar cells.  Read More

A new tool for researching neurodegenerative diseases such as Alzheimer's takes its inspir...

In order to detect the presence of nearby females, the male silk moth utilizes an oily coating on his antennae. Any female pheromone molecules that are in the air will stick to that coating, which then guides them through nanotunnels in the insect's exoskeleton, and ultimately to nerve cells that alert Mr. Moth to the fact that there are ladies in the area. It's a clever enough system that scientists from the University of Michigan have copied it, in hopes of better understanding neurodegenerative diseases such as Alzheimer's.  Read More

Researchers from the University of Michigan have created what they claim is the world’s first millimeter-scale complete computing system, designed as an implantable eye pressure monitor for glaucoma patients. Incorporating a microprocessor, pressure sensor, memory, thin-film battery, solar cell and wireless radio with an antenna that can transmit data to an external reader device, the device is just over one cubic millimeter in size. The scientists see it as the next step in the evolution of ever-smaller and more efficient computers.  Read More

Organic light-emitting diodes (OLEDs) are a technology that shows great promise, as they are thinner, lighter, and less expensive to manufacture than their non-organic LED counterparts. Despite their name, however, they are not fully organic, as small amounts of precious metals are required to make them glow. A completely organic and even cheaper alternative could be on its way, though ... researchers from the University of Michigan have created metal-free organic crystals that shine with phosphorescence – until now, only non- or semi-organic compounds have displayed this property.  Read More

Despite ongoing advances in prevention techniques and monitoring systems, heart disease remains the world’s leading cause of death. A study from the University of Michigan (U-M) Cardiovascular Center has looked to the past for a future remedy in a study that examines the legality and basic logistics of recycling pacemakers after they have been removed from a deceased person.  Read More

Researchers have created a tabletop device that produces synchrotron X-rays, the energy and image quality of which are as good as some of the largest, most expensive X-ray facilities on the planet. It uses a high power laser combined with a tiny jet of helium gas to produce an ultrashort high energy beam, that could be used for everything from examining molecules to checking the integrity of airplane wings.  Read More

Examples of the 3D nanotube structures created by capillary forming (Photo: A. John Hart)

Carbon nanotubes, despite all the technological advances they’re making possible, look pretty boring. When viewed though a microscope, they are, essentially, just straight tubes. Now scientists from the University of Michigan have used a process called “capillary forming” to create nanotubes that resemble twisting spires, concentric rings, and bending petals. It's not about aesthetics though, giving nanotubes complex 3D shapes is seen as an important breakthrough in the development of microdevices and nanomaterials.  Read More

New laser technology could be used to protect military helicopters from heat-seeking missi...

Researchers at the University of Michigan are developing laser systems for protecting military helicopters from heat-seeking missiles. The lasers wouldn’t shoot down the missiles, but would instead jam their sensors, essentially blinding them. This isn’t the first time that laser systems have been used for this purpose, but the creators of this system claim that it is better suited to helicopters than anything that has come before.  Read More

Researchers from the University of Michigan have unveiled a more efficient, brighter and h...

Only a small percentage of backlight actually makes its way out through the multiple layers that make up the ubiquitous LCD displays we use today. That may change with the development of new filter technology at the University of Michigan. White light is sent through tiny, precisely spaced gaps on nano-thin sheets of aluminum and is said to result in brighter, higher definition color reproduction. Other benefits of the technology include efficiency gains and simpler manufacturing.  Read More
