Marco Di Lucca shared a closer look at his latest digital human, created for NVIDIA’s Computex 2024 keynote.

The Dark Energy Spectroscopic Instrument (DESI) is a robotic instrument and spectrograph mounted on the Mayall Telescope in Kitt Peak, Arizona. The DESI collaboration aims primarily to understand the elusive Dark Energy. This is an energy of unknown source causing the Universe to accelerate in its expansion; this accelerating expansion is not predicted to occur for a universe that is filled with just ordinary matter and radiation (some more detail can be seen in this Astrobite). Since we still know so little about Dark Energy, a large galaxy survey can allow us to explore the history of the expansion of the Universe in more detail. The DESI instrument has 5,000 individual optical fibres controlled by robots that allow it to measure individual spectra of up to 5,000 galaxies in just a mere 20 minutes! Due to this design, and an observing program that optimises targets in the sky based on observing conditions, the survey will measure spectra of up to 35 million galaxies over 5 years. This will allow DESI to perform precise cosmological measurements, as a great volume of space and number of galaxies can be probed, and noise in the data products is reduced. This bite looks at the cosmology results from the collaboration’s analysis of the recently released Year 1 Data (YR1), in particular, via a signal that can be seen in the data known as Baryon Acoustic Oscillations.

A potentially controversial new study suggests that the universe’s expansion may be a mirage.

This new perspective on the universe may also provide answers to the mysteries surrounding dark energy and dark matter, which scientists estimate make up about 95% of all the energy and matter in the universe but are still poorly understood.

I disagree with you Dan Breeden. In my openion AI WILL A BETTER FUTURE FOR HUMAN CIVILIZATION.

Doctors and engineers from Massachusetts General Hospital and MIT are trying to revolutionize cancer detection through an artificial intelligence program called Sybil. Their study found that Sybil could accurately predict whether a person will develop lung cancer in the next year up to 94 percent of the time. NBC News’ Dr. John Torres reports.

A team of New York University researchers has created a new way to visualize crystals by peering inside their structures, akin to having X-ray vision. Their new technique—which they aptly named “Crystal Clear”—combines the use of transparent particles and microscopes with lasers that allow scientists to see each unit that makes up the crystal and to create dynamic three-dimensional models.

Starlink achieves ‘a new internal median latency record’ of 28 milliseconds, Elon Musk says.

Experts from Germany believe their most recent breakthrough advances the quality of solid-state, sodium-ion batteries.

It’s technology that many researchers are pursuing as a replacement for common lithium-ion power packs, with the hope of finding a better-performing and cheaper alternative.

Several passengers on a United Airlines flight from Vancouver, Canada, to Houston, Texas, fell sick on Friday, with officials explaining that 75 passengers came from a cruise.

Some systems are still down, but medical staff can now use the computer system for patient care after almost four weeks.
