‘Tremendous technical challenges’: New report says NASA won’t land astronauts on the moon in 2025

Posted by in categories: government, space travel

Man’s return to the moon may be delayed from 2025 until 2027.

BREVARD COUNTY, Fla. — NASA will miss its mark trying to land astronauts on the moon by 2025. That’s according to a new report, released by the Government Accountability Office (GAO) this week.

“There are tremendous technical challenges that have to be resolved,” said Ken Kremer. He’s a space journalist in Brevard County who read and analyzed the new report.

Long in the Bluetooth: Scientists develop a more Efficient way to Transmit Data between Our Devices

Posted by in categories: mobile phones, wearables

University of Sussex researchers have developed a more energy-efficient alternative to transmit data that could potentially replace Bluetooth in mobile phones and other tech devices. With more and more of us owning smart phones and wearable tech, researchers at the University of Sussex have found a more efficient way of connecting our devices and improving battery life. Applied to wearable devices, it could even see us unlocking doors by touch or exchanging phone numbers by shaking hands.

Professor Robert Prance and Professor Daniel Roggen, of the University of Sussex, have developed the use of electric waves, rather than electromagnetic waves, for a low-power way to transmit data at close range, while maintaining the high throughput needed for multimedia applications.

Bluetooth, Wifi, and 5G currently rely on electromagnetic modulation, a form of wireless technology which was developed over 125 years ago.

Certain Skin Bacteria can Inhibit Growth of Antibiotic-Resistant Bacteria

Posted by in category: biotech/medical

Researchers have found a bacteriocin that can help inhibit the growth of antibiotic-resistant bacteria. Infections with antibiotic-resistant bacteria are a growing global problem. Part of the solution may lie in copying the bacteria’s own weapons. The research environment in Tromsø has found a new bacteriocin, in a very common skin bacterium. Bacteriocin inhibits the growth of antibiotic-resistant bacteria that are often the cause of disease and can be difficult to treat.

One million deaths each year.

The fact that we have medicines against bacterial infections is something many people take for granted.

OpenGPT is an open-source alternative to OpenAI’s custom ChatGPTs

Posted by in categories: futurism, robotics/AI

OpenGPT is a promising toolkit for building custom chatbots like GPTs, but it is completely open-source and offers even more configuration options. Which means it is also more complicated.

With GPTs, OpenAI introduced the evolution of its plugin concept at Dev Days in November 2023. The AI company is giving end users different tools to create a chatbot tailored to their needs, without having to know how to code a chatbot. OpenAI even plans to give successful GPT creators a share of the revenue from ChatGPT Plus in the future.

When setting up GPTs, users can upload their files, link APIs, assign system prompts, and enable modules for web browsing, DALL-E, and code interpreters.

Physicists May Have Found a Hard Limit on The Performance of Large Quantum Computers

Posted by in categories: computing, quantum physics

A newly discovered trade-off in the way time-keeping devices operate on a fundamental level could set a hard limit on the performance of large-scale quantum computers, according to researchers from the Vienna University of Technology.

While the issue isn’t exactly pressing, our ability to grow systems based on quantum operations from backroom prototypes into practical number-crunching behemoths will depend on how well we can reliably dissect the days into ever finer portions. This is a feat the researchers say will become increasingly more challenging.

Whether you’re counting the seconds with whispers of Mississippi or dividing them up with the pendulum-swing of an electron in atomic confinement, the measure of time is bound by the limits of physics itself.

Thought To Be Impossible — Scientists Uncover Hidden World Using Newly Found Properties of a Graphene-Like Material

Posted by in categories: innovation, materials

A breakthrough in nanofluidics is set to revolutionize our grasp of molecular dynamics at minuscule scales. Collaborative efforts from scientists at EPFL and the University of Manchester have uncovered a previously hidden world by using the newly found fluorescent properties of a graphene-like 2D material, boron nitride. This innovative approach enables scientists to track individual molecules within nanofluidic structures, illuminating their behavior in ways never before possible. The study’s findings were recently published in the journal Nature Materials.

Nanofluidics, the study of fluids confined within ultra-small spaces, offers insights into the behavior of liquids on a nanometer scale. However, exploring the movement of individual molecules in such confined environments has been challenging due to the limitations of conventional microscopy techniques. This obstacle prevented real-time sensing and imaging, leaving significant gaps in our knowledge of molecular properties in confinement.

From Microbes to Artificial Life: Harnessing Bacterial Motors for Nanomachines

Posted by in categories: biological, nanotechnology

A research group has made new insights into how locomotion occurs in bacteria. The group identified the FliG molecule in the flagellar layer, the ‘motor’ of bacteria, and revealed its role in the organism. These findings suggest ways in which future engineers could build nanomachines with full control over their movements.

The researchers, who were led by Professor Emeritus Michio Homma and Professor Seiji Kojima of the Graduate School of Science at Nagoya University, in collaboration with Osaka University and Nagahama Institute of Bio-Science and Technology, published the study in iScience.
