Better genome editing

UCSB researchers have developed a highly efficient genome editing method that offers complete spatiotemporal control, allowing users to target specific cells or regions within the cell. This approach enables precise and transient gene editing with minimal long-term effects on DNA.

Preparing for chemical attacks with improved computer models

University of Texas at San Antonio researchers have developed improved computer models to predict the dispersal of chemical plumes, enabling more accurate evacuations. The models can simulate real-world conditions despite limited information, providing critical insights into the spread of toxic agents like sarin gas.

Antipsychotic use in older adults after heart surgery

A recent study found that antipsychotic medications are not proven to be effective for treating delirium in older adults after heart surgery, and may even cause heart rhythm problems and other dangerous side effects. The study suggests that the use of these medications is excessive and warrants more appropriate prescribing practices.

How the brain suppresses the act of revenge

A UNIGE team discovered which brain zones are activated in anger and how the brain suppresses the act of revenge. The prefrontal dorsolateral cortex (DLPFC) plays a key role in regulating emotions, with higher activity during provocation phases leading to less punishment against unfair players.

Illinois study pioneers humane feline research facility

Researchers at the University of Illinois created a unique study environment for cats to advance science and test an injectable contraceptive vaccine. The hybrid facility, dual-licensed as a USDA research facility and animal shelter, provided enriching conditions with furniture, toys, and outdoor enclosure.

Switching DNA and RNA on and off

Scientists find that DNA and RNA have memory properties, with two stable states, making them suitable for storing data. The minimum electric field required for switching is inversely proportional to the ratio of topological polar surface area to total surface area.

Picture this: Camera with no lens

Researchers created a lensless camera by connecting a digital sensor to a plexiglass window, which acts as a makeshift lens. The system can capture recognizable images with computer algorithms decoding the pixelated data. This innovation opens up possibilities for various applications, including augmented reality goggles and biometric ...

Nanobot pumps destroy nerve agents

Researchers create nanobot pumps that neutralize nerve agents and administer antidotes, powered by the enzyme's chemical energy. The technology has applications in medicine, manufacturing, robotics, and fluidics, and could be used to treat diseases like diabetes and deliver targeted treatments.

FDA research informs smokeless tobacco prevention messaging for at-risk youth

Recent FDA research identified effective health messaging strategies for rural, non-Hispanic White males aged 12-17 years who are at risk of initiating or experimenting with smokeless tobacco. The findings suggest that authenticity and straightforward facts about the health consequences of SLT use resonate well with this audience.

First in-depth profile of CAR T-cell signals suggests how to improve immunotherapy

Researchers at Fred Hutchinson Cancer Center compared two common CAR designs in lab models and found that the CD28 CAR showed faster and stronger activity, while the 4-1BB CAR was more effective in clearing cancer cells. The study provides insights into how to improve immunotherapy by designing future generations of CAR T-cell therapies.
