RNA interference (RNAi) technology can specifically silence the expression of a target gene and has emerged as a promising therapeutic method to treat cancer. In the present study, we showed that natural halloysite nanotube (HNT)–assisted delivery of an active small interfering RNA (siRNA) targeting receptor-interacting protein kinase 4 ( RIPK4 ) efficiently silenced its expression to treat bladd

Genes lost during the transition from land to water in cetaceans highlight genomic changes associated with aquatic adaptations
The transition from land to water in whales and dolphins (cetaceans) was accompanied by remarkable adaptations. To reveal genomic changes that occurred during this transition, we screened for protein-coding genes that were inactivated in the ancestral cetacean lineage. We found 85 gene losses. Some of these were likely beneficial for cetaceans, for example, by reducing the risk of thrombus format

How a biofriendly fertilizer could offer a greener way to grow plants
Every year, a "dead zone" the size of Massachusetts sprawls across the Gulf of Mexico. The Mississippi River, which travels through the nation's farm belt, sweeps excess fertilizer and dumps the chemicals into the Gulf, where they feed rampant algae, deplete oxygen, and kill marine life.

MRI marker better predicts progression of multiple sclerosis
Atrophied brain lesion volume is the only marker from MRI scans that can accurately predict which patients with multiple sclerosis will progress to the most severe form of the disease, a new study shows. Secondary progressive MS, known as SPMS, typically appears 10 to 20 years after the initial onset and causes more physical and cognitive impairments. Of the 1,314 patients in the 5-year study, mo

Engineered protein crystals make cells magnetic
If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside them have resulted in only weak magnetic forces. Now, researchers reporting in ACS' Nano Letters have engineered genetically encoded protein crystals that can generate magnet

Physicists take new step towards realization of qubits for quantum computers
A group of physicists in Utrecht, San Sebastián and Pennsylvania have created a new artificial molecule that is insulating inside but has electronic states localized in its corners. These states have zero energy, and for this reason, are resilient to defects in the molecule and might be used as qubits in quantum computers. The results are published in Nature Materials on 23 September.
