A lot of the hype today centers on the idea of developers using AI âto write their code.â This is not practical, at least not for complex tasks. However, AI does have some strengths:
âą Producing first drafts of code.
âą Minor code updates.
âą Automating repetitive tasks.
âą Producing code summaries.
BREMEN, Germany â Lunar Outpost has selected SpaceXâs Starship vehicle to deliver to the moon the Artemis lunar rover it is developing for potential use by NASA.
The Colorado company announced Nov. 21 that it signed an agreement for SpaceX to use Starship to transport the companyâs Lunar Outpost Eagle rover to the moon. The companies did not disclose a schedule for the launch or other terms of the deal.
Lunar Outpost is one of three companies that won NASA contracts in April for the first phase of the Lunar Terrain Vehicle (LTV) program to support the development of a rover that can be used by future Artemis missions. Each company received a one-year contract to mature the design of their rovers through a preliminary design review (PDR), and the agency will later select at least one of the companies to develop the rover.

Now that AI is transforming nearly every industry, healthcare stands out as a field with immense potential â and unique risks.
A single AI-generated error here could lead to serious consequences for patient health.
Mapping in the Chukchi and Beaufort seas off Alaska has uncovered a 1,640-foot-tall structure on the seafloor, but scientists say itâs too early to determine the nature of the discovery.
Biomedical engineers from the University of Melbourne have invented a 3D printing system, or bioprinter, capable of fabricating structures that closely mimic the diverse tissues in the human body, from soft brain tissue to harder materials like cartilage and bone.
This cutting-edge technology offers cancer researchers an advanced tool for replicating specific organs and tissues, significantly improving the potential to predict and develop new pharmaceutical therapies. This would pave the way for more advanced and ethical drug discovery by reducing the need for animal testing.
Head of the Collins BioMicrosystems Laboratory at the University of Melbourne, Associate Professor David Collins said: In addition to drastically improving print speed, our approach enables a degree of cell positioning within printed tissues. Incorrect cell positioning is a big reason most 3D bioprinters fail to produce structures that accurately represent human tissue.
Within the body, cells involved in specific functions, like immune response and secretion, are equipped with granules, which are small membrane-bound compartments containing enzymes, proteins, or other molecules. In neutrophils, the so-called azurophilic (or primary) granules contain enzymes that are involved in the initial response to an infection.
MPO-based E-101 is the first wound and systemically safe antiseptic, with a safety profile comparable to saline, that is effective in physiological conditions.
Myeloperoxidase, or MPO, is one of the most important of such enzymes for the immune systemâs ability to destroy pathogens. Allen has been studying the physiological role of MPO since 1971. Using chemiluminescence and metabolic studies he has been able to study the complex and finely regulated mechanism of NADPH oxidase driven MPO action in microbicidal activity.
A SPACEPLANE that uses regular runways could fly to space as soon as next year.
Called Dream Chaser, the futuristic spacecraft will fly on a NASA mission to resupply the International Space Station.
The mission â officially called SSC Demo-1 â is due to take place âno earlier than May 2025â
New research from the Kind Group at the Hubrecht Institute sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells.
The study demonstrates how these proteins collaborate in so-called âhubsâ to repair DNA damage. This knowledge offers opportunities to improve cancer therapies and other treatments where DNA repair is essential. The researchers published their findings in Nature Communications on November 21.
DNA is the molecule that carries our genetic information. It can be damaged by normal cellular processes as well as external factors such as UV radiation and chemicals. Such damage can lead to breaks in the DNA strand. If DNA damage is not properly repaired, mutations can occur, which may result in diseases like cancer. Cells use repair systems to fix this damage, with specialized proteins locating and binding to the damaged regions.
