NASA Investigating Whether It Could Hire SpaceX for Mars Trip

Posted by in category: space travel

NASA is debating whether to work with commercial partners to get to Mars.

And while SpaceX is the “elephant in the room,” as Ars Technica put it, NASA is keeping its options wide open.

It’s a notable change, as the first time the space agency has openly raised the possibility of working with private space companies to reach Mars.

Polar plastic: 97% of sampled Antarctic seabirds found to have ingested microplastics

Posted by in category: materials

Anthropogenic plastic pollution is often experienced through evocative images of marine animals caught in floating debris, yet its reach is far more expansive. The polar regions of the Arctic and Antarctica are increasingly experiencing the impacts of plastic reaching floating ice and land, not solely as larger macroplastics (>5 cm), but as microplastics (0.1 µm—5 mm) and nanoplastics (<0.1 µm) that may be carried vast distances from their source or be ingested in more populated areas during seasonal migration.

Researcher Startled When AI Seemingly Realizes It’s Being Tested

Posted by in category: robotics/AI

Anthropic’s new AI chatbot Claude 3 Opus has already made headlines for its bizarre behavior, like claiming to fear death.

Now, Ars Technica reports, a prompt engineer at the Google-backed company claims that they’ve seen evidence that Claude 3 is self-aware, as it seemingly detected that it was being subjected to a test. Many experts are skeptical, however, further underscoring the controversy of ascribing humanlike characteristics to AI models.

“It did something I have never seen before from an LLM,” the prompt engineer, Alex Albert, posted on X, formerly Twitter.

Grimshaw and UEL develop sugarcane-waste construction blocks

Posted by in categories: materials, sustainability

Using sugarcane waste as bricks for construction.


Architecture studio Grimshaw and the University of East London have collaborated to create Sugarcrete, a biomaterial construction block with an interlocking shape made from the sugarcane by-product bagasse.

Sugarcrete was developed to be a low-cost and low-carbon reusable construction-material alternative to brick and concrete.

‘Immortality protein’ within the mitochondria offers protection in myocardial infarction

Posted by in categories: biotech/medical, life extension

Year 2021 😗😁😘


Researchers Prof. Judith Haendeler from the Medical Faculty and the molecular biologist Prof. Joachim Altschmied from the Department of Biology, together with their teams, have shown for the first time in the cardiovascular system that telomerase reverse transcriptase (TERT) within the mitochondria, the powerhouses of the cells, has a protective function in myocardial infarction. This work, which was performed together with other groups from the University Hospital Düsseldorf and the University Hospital Essen within the frame of the Collaborative Research Center 1,116, was recently published in the journal Circulation.

Cardiac muscle cells benefit from the increased mitochondrial function and are protected from cell death. Other also profit from increased mitochondrial function such as fibroblasts, which are essential for stable scarring after an infarction, and , which are needed for vascularization and thus blood supply in the infarct area.

Chemical reactions can scramble quantum information as well as black holes

Posted by in categories: chemistry, cosmology, quantum physics

If you were to throw a message in a bottle into a black hole, all of the information in it, down to the quantum level, would become completely scrambled. Because in black holes this scrambling happens as quickly and thoroughly as quantum mechanics allows. They are generally considered nature’s ultimate information scramblers.
