Although there are now some preventive measures to alleviate food allergies, there are not yet any long-lasting solutions—treatments capable of locking the immune system into a state of tolerance, so that it doesn't respond to allergens. Now, a UCLA research team has developed a possible way to impart long-term relief from allergies by inducing an active state of immune tolerance. The technology uses nanoparticles to deliver proteins to the liver that can activate a tolerant immune response and switch the allergic response off.

There is currently no cure for osteoarthritis, but a group of scientists from the United States, Canada, and China has discovered a method through which a simple knee injection could potentially stop the disease's effects. The researchers created nanotherapeutics that they injected into mice that already had cartilage damage in their knees. The researchers noticed that these injections slowed cartilage degeneration and bone hardening and eased knee pain. No major side effects were seen in the mice that were treated.

Researchers at Columbia Engineering have developed the first nanomaterial that demonstrates "photon avalanching," a process that is unrivaled in its combination of extreme nonlinear optical behavior and efficiency. The realization of photon avalanching in nanoparticle form opens up a host of applications, from real-time super-resolution optical microscopy, precise temperature and environmental sensing, and infrared light detection, to optical analog-to-digital conversion and quantum sensing.

Scientists at Rice University have developed a technique to turn pyrolyzed plastic ash, a product of plastic recycling, into graphene. The technique produces turbostratic graphene flakes that can be directly added to other substances, such as films of polyvinyl alcohol, that better resist water in packaging. Last October, the same scientists reported on a process to convert waste plastic into graphene. This time, the new process turns plastic that is not recovered by recycling into a useful product.

When two atomically thin layers of a material are stacked and twisted slightly on top of one another, they can develop radically different properties. They may become superconducting or even develop magnetic or electronic properties due to the interaction of their two layers. Now, a research team from the United States and Germany has developed a groundbreaking method to map the interaction between such ultra-thin double layers.

Physicists at Washington University in St. Louis have discovered how to locally add electrical charge to an atomically thin graphene device by layering flakes of another thin material on top of it. Gaining control of the flow of electrical current through atomically thin materials is important to potential future applications in photovoltaics or computing.
