New study identifies 4,749 key gene clusters that influence progression of 32 cancer types

Posted by in categories: biotech/medical, genetics

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’s Mars robots are on their own right now — here’s why

Posted by in categories: robotics/AI, space

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.

MIT researchers use ultrasonic laser pulses to probe metamaterials

Posted by in category: materials

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


Eurekalert.

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.

New 3D printing technology enables more durable and flexible robots

Posted by in categories: 3D printing, robotics/AI

This opens up new possibilities for creating complex robots with soft and rigid materials in one go.

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.

Scientists debunk notions of optogenetics controlling the human brain

Posted by in categories: biotech/medical, genetics, robotics/AI

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.

Cosmic ray electrons from nearby supernovae detected by ISS

Posted by in category: cosmology

A new study using data from the CALET instrument on the ISS has found evidence for young and nearby sources of cosmic ray electrons from supernova remnants.


NASA

In a new study using data from the CALorimetric Electron Telescope (CALET) instrument on the ISS, the researchers have found evidence for young and nearby sources of cosmic ray electrons, which are a special kind of cosmic ray that carry a negative charge. These sources will likely be the remnants of exploded stars, or supernovae, in our galactic neighborhood.

China’s achievements in wired data transmission come shortly after the country boasted about the installation of 3.19 million base stations, demonstrating 5G dominance in wireless telephony. Not only do these installations outpace the US in sheer numbers, but they are also helping the eastern country transform its industrial sector to engage in high-tech manufacturing, Interesting Engineering had previously reported.
