Altered protein translation elongation contributes to brain aging

The GFP gene, which has its origins in jellyfish, expresses proteins that fluoresce when illuminated with certain frequencies of light. Poeschla, of the Mayo Clinic in Rochester, Minnesota, reported his results in the journal Nature Methods.

This function is regularly used by scientists to monitor the activity of individual genes or cells in a wide variety of animals. The development and refinement of the GFP technique earned its scientific pioneers the Nobel prize for chemistry in 2008.

In the case of the glowing cats, the scientists hope to use the GM animals in the study of HIV/AIDS.

World’s largest-scale brain-like computer with 2 billion neurons unveiled

Engineers in China unveiled a new generation of brain-like computer that mimics the workings of a macaque monkey’s brain.

Called Darwin Monkey, the system reportedly supports over 2 billion spiking neurons and more than 100 billion synapses, with a neuron count approaching that of a macaque brain.

Reports have revealed that the system consumes approximately 2,000 watts of power under typical operating conditions.

Muscle-inspired sheet-like robot navigates the tightest spaces

A POSTECH research team has developed a thin, flexible robotic actuator inspired by human muscle proteins. As thin as paper, yet capable of generating strong forces, this robot can maneuver through tight spaces and manipulate objects, making it suitable for a wide range of applications—from surgical robots to industrial equipment. The study has been published in Nature Communications.

Most conventional robots are built with rigid metal components, giving them strength but limiting their ability to perform delicate motions or operate in confined environments.

In the medical field, there is a growing need for robots that can assist with surgeries inside the . In industrial settings, flexible robots are needed for tasks like inspecting complex machinery or cleaning narrow pipelines. However, technologies that combine both flexibility and strength have been lacking—until now.

In vitro anti-cancer efficacy and phyto-chemical screening of solvent extracts of Kigelia africana (Lam.) Benth

Kigelia africana is a medicinal plant growing naturally in many parts of Africa. In Kenya, a water concoction of the plant is used to treat breast and prostate cancers. Laboratory data on its anti-cancer activity and active principles is limited, hence no scientific rationale for its medicinal use. This study reports on in-vitro toxic activities of dichloromethane and methanol extracts of the plant against human breast cancer cells and phytochemical screening of the two extracts.

Scientists develop microscopic ‘swimming’ discs that could help clean polluted waters: ‘Pave the way for applications’

A team of researchers has created small swimmers that can harvest energy from their surroundings and convert it into movement. The discs, about twice as wide as a human hair, are amazingly partly made from dried food dye, according to a news release from New York University.

The fascinating project includes experts from Harvard, the University of Chicago, and elsewhere.

“The essential new principles we discovered — how to make microscopic objects swim on command using simple materials that undergo phase transitions when exposed to controllable energy sources — pave the way for applications that range from design of responsive fluids, controlled drug delivery, and new classes of sensors, to name a few,” lead researcher Juan de Pablo, from NYU, said in the summary.
