3D printing is advancing rapidly, and the range of materials that can be used has expanded considerably. While the technology was previously limited to fast-curing plastics, it has now been made suitable for slow-curing plastics as well. These have decisive advantages as they have enhanced elastic properties and are more durable and robust.

The use of such polymers is made possible by a new technology developed by researchers at ETH Zurich and a US start-up. As a result, researchers can now 3D print complex, more durable robots from a variety of high-quality materials in one go. This new technology also makes it easy to combine soft, elastic, and rigid materials. The researchers can also use it to create delicate structures and parts with cavities as desired.

Summary: Researchers made a breakthrough in memory research by genetically modifying the LIMK1 protein, crucial for memory, to be controlled by the drug rapamycin.

This study demonstrates the ability to enhance memory functions by manipulating synaptic plasticity in the brain.

The engineered protein showed significant memory improvement in animal models with age-related cognitive decline, offering potential for innovative treatments for neuropsychiatric diseases like dementia. This ‘chemogenetic’ approach, blending genetics and chemistry, opens new avenues in neurological research and therapy.

Microsoft will give its Azure cloud clients more choices for standard computing workloads and artificial intelligence, following market leader Amazon.

Researchers at the Mount Sinai Center for Transformative Disease Modeling have released a groundbreaking study identifying 4,749 key gene clusters, termed “prognostic modules,” that significantly influence the progression of 32 different types of cancer. The study, published in Genome Research, serves as a comprehensive resource and lays the foundation for the development of next-generation cancer treatments and diagnostic markers.

Despite significant progress in cancer research, understanding the disease’s genetic intricacies remains challenging. Previous research often focused on isolated gene functions in specific cancer types.

We aimed to fill this knowledge gap by providing a comprehensive analysis of gene-gene interactions across various forms of cancer.

NASA has temporarily stopped sending commands to its Mars-exploring robots, but there’s nothing to worry about.

We’re currently experiencing a “Mars solar conjunction,” a two-week stretch in which Earth and the Red Planet are situated on opposite sides of the sun. Mars mission teams halt commands during such alignments, which occur roughly every two years, for safety reasons.

The apparatus can be easily replicated by other laboratories accelerating the entry of metamaterials in the real world.

Metamaterials are products made from everyday materials such as polymers, ceramics, and metals. When mixed in the right proportions and constructed precisely at microscales, these materials can assume extraordinary properties.

3D printing is a revolutionary technology that can create objects of any shape and size from various materials. However, until now, it was mostly limited to using fast-curing plastics, which have some drawbacks. They are brittle, prone to cracking, and lose their shape easily when bent.

In an exclusive interview, Peter Hegemann said AI is more dangerous than optogenetics.

Contrary to popular belief, there is very little chance that optogenetics will be used in the future to control the human brain, says Peter Hegemann, a biochemist and biophysicist, in a conversation with Interesting Engineering (IE) at the Hong Kong Laureate Forum 2023.

Optogenetics is a scientific technique that uses light to control and manipulate cells within living tissues, particularly in the brain. It allows researchers to control the activity of specific neurons with high precision, both in terms of location and timing.
