Novel home cleaning method to reduce asthma

Novel home cleaning method to reduce asthma

A team of researchers from the University of South Carolina received two patents for a new method to rid carpets, mattresses and other furniture of harmful allergens and pests that cause asthma. The patents (Methods and Compositions for Eliminating Allergens and Allergen-Producing Organisms) are the work of Michael Matthews, Jian Zhang and Allan Quick and uses carbon dioxide (CO 2 ) to “freeze clean” home fabrics.

Breakthrough method for making Janus or patchy capsules

Breakthrough method for making Janus or patchy capsules

Hollow capsules that have a selectively permeable shell are promising candidates as tiny containers for molecules, particles or bubbles, and are becoming increasingly important in a wide variety of applications. But making these kinds of capsules with more than one kind of substance on their shells has been challenging — until now Continue reading

Going beyond the surface: New tech could take light-based cancer treatment deep inside the body

Going beyond the surface: New tech could take light-based cancer treatment deep inside the body

Photodynamic therapy (PDT) is an effective treatment for easily accessible tumors such as oral and skin cancer. But the procedure, which uses lasers to activate special drugs called photosensitizing agents, isn’t adept at fighting cancer deep inside the body. Thankfully, that’s changing due to new technology that could bring PDT into areas of the body which were previously inaccessible. Continue reading

New implanted devices may reshape medicine: Researchers create transistors that wrap around tissues

New implanted devices may reshape medicine: Researchers create transistors that wrap around tissues

Researchers from The University of Texas at Dallas and the University of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels. These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments. The research, available online and in an upcoming print issue of Advanced Materials , is one of the first demonstrations of transistors that can change shape and maintain their electronic properties after they are implanted in the body, said Jonathan Reeder BS’12, a graduate student in materials science and engineering and lead author of the work Continue reading

Alternative pathways let right and left communicate in early split brains

Alternative pathways let right and left communicate in early split brains

During the last century, many patients have undergone a variety of brain surgeries in an attempt to alleviate all sorts of psychiatric maladies, from hysteria and depression (mainly in women) to schizophrenia and epilepsy. Early on, doctors believed that psychiatric patients suffered from aberrant wiring among different brain areas and that cutting the connections between these areas would help patients regain normal brain circuits as well as their mental health. For instance, since the 1940s, several patients with intractable epilepsy have been treated with callosotomy, a surgical procedure that severs part or most of the corpus callosum. Continue reading

Flexible supercapacitor raises bar for volumetric energy density; Could be woven into clothes to power devices

Flexible supercapacitor raises bar for volumetric energy density; Could be woven into clothes to power devices

Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics. The device is a supercapacitor — a cousin to the battery. This one packs an interconnected network of graphene and carbon nanotubes so tightly that it stores energy comparable to some thin-film lithium batteries — an area where batteries have traditionally held a large advantage.

Gene behind highly prevalent facial anomaly found

Gene behind highly prevalent facial anomaly found

Whitehead Institute scientists have identified a genetic cause of a facial disorder known as hemifacial microsomia (HFM). The researchers find that duplication of the gene OTX2 induces HFM, the second-most common facial anomaly after cleft lip and palate Continue reading

The promise of purple for enhanced bioimaging

The promise of purple for enhanced bioimaging

Newly detected ‘energy-clustering’ structures inside rare-earth nanoparticles generate intense violet light, which is ideal for studying photon-induced transformations. Labeling biomolecules with light-emitting nanoparticles is a powerful technique for observing cell movement and signaling under realistic, in vivo conditions. Continue reading
