Record-Setting Mars Orbiter Captures New View of Monster Volcano

Posted by in category: space

Earth’s largest volcano is Hawaii’s Mauna Loa, a shield volcano with a volume of 18,000 cubic miles. Olympus Mons is 100 times larger. It covers an area 373 miles (600 kilometers) across, about the size of the state of Arizona, and its summit is 17 miles (27 kilometers) high. That is twice the altitude at which commercial jets fly on Earth. Those are both huge measurements for a volcanic feature, but the incredible surface area makes the height look less impressive.

“Normally we see Olympus Mons in narrow strips from above, but by turning the spacecraft toward the horizon we can see in a single image how large it looms over the landscape,” said Odyssey project scientist Jeffrey Plaut.

Odyssey has been orbiting Mars for more than 20 years, having arrived in 2001 to search for water ice buried under the surface. It has spent all these years looking straight down, but NASA fired the probe’s thrusters to reorient it to point the Thermal Emission Imaging System (THEMIS) at the horizon. That’s how mission managers got the panorama below.

Tesla Giga Berlin expansion gets approval from authorities: report

Posted by in categories: sustainability, transportation

Recent reports have noted that Tesla Germany has received permission to expand Giga Berlin from the Brandenburg State Office for the Environment, as per the Ministry of the Environment. With the approval in place, Tesla could start construction work ahead of schedule.

The Ministry of the Environment noted that the early start of construction involves the buildout of an asphalted logistics area for new vehicles, the construction of underground lines and staircases at the press shop, and the installation of rooftop solar panels. As per German publication Stern, Chancellor Olaf Scholz (SPD) has expressed his support for the Tesla Model Y factory’s expansion.

The approval for Giga Berlin’s expansion is expected to pave the way for the facility to increase its vehicle production output. It should be noted, however, that the approval that Tesla Germany was able to secure was only for expansion of the existing Giga Berlin facility. Further forest clearing activities, which are required for Tesla’s plan to build a railway station in the complex, still require permissions.

Experts warn NASA to contain ‘space viruses’. Will these wipe out entire civilization?

Posted by in category: space

Biodefence experts have asked NASA to crack down on ‘space viruses’ and stop them from affecting humans as some viruses loitering in space have unknown potential and can put the entire civilization in danger, according to reports.

Searching for dark matter with the coldest quantum detectors in the world

Posted by in categories: cosmology, particle physics, quantum physics

One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly—possibly at a rate of trillions of particles per second.

We know it exists because we can see the effects of its gravity, but experiments to date have so far failed to detect it.

Taking advantage of the most advanced quantum technologies, scientists from Lancaster University, the University of Oxford, and Royal Holloway, University of London are building the most sensitive dark matter detectors to date.

Song melodies have become simpler since 1950, study suggests

Posted by in category: media & arts

The complexity of the melodies of the most popular songs each year in the U.S.—according to the Billboard year-end singles charts—has decreased since 1950, a study published in Scientific Reports suggests.

Madeline Hamilton and Marcus Pearce analyzed the most prominent melodies (usually the vocal ) of songs that reached the top five positions of the US Billboard year-end singles music charts each year between 1950 and 2022. They found that the complexity of rhythms and pitch arrangements decreased over this period as the average number of notes played per second increased. They also identified two significant decreases in melodic complexity that occurred in 1975 and 2000, along with a smaller decrease in 1996.

The authors speculate that the melodic changes that occurred in 1975 could represent the rise of genres such as new wave, disco and stadium rock. Those occurring in 1996 and 2000 could represent the rise of hip-hop or the adoption of digital audio workstations, which enabled the repeated playing of audio loops, they add.

Key mechanisms identified for regeneration of neurons

Posted by in categories: biotech/medical, life extension, neuroscience

Neurological disorders, such as trauma, stroke, epilepsy, and various neurodegenerative diseases, often lead to the permanent loss of neurons, causing significant impairments in brain function. Current treatment options are limited, primarily due to the challenge of replacing lost neurons.

Direct neuronal , a complex procedure that involves changing the function of one type of cell into another, offers a promising strategy.

In cell culture and in living organisms, glial cells—the non-neuronal cells in the central nervous system—have been successfully transformed into functional neurons. However, the processes involved in this reprogramming are complex and require further understanding. This complexity presents a challenge, but also a motivation, for researchers in the field of neuroscience and regenerative medicine.

Physicists develop method to detect single-atom defects in semiconductors

Posted by in categories: materials, particle physics

One of the challenges of cramming smarter and more powerful electronics into ever-shrinking devices is developing the tools and techniques to analyze the materials that make them up with increasingly intimate precision.

Physicists at Michigan State University have taken a long-awaited step on that front with an approach that combines high-resolution microscopy with ultrafast lasers.

The technique, described in the journal Nature Photonics, enables researchers to spot misfit atoms in semiconductors with unparalleled precision. Semiconductor physics labels these atoms as “defects,” which sounds negative, but they’re usually added to materials on purpose and are critically important to the performance of semiconductors in today’s—and tomorrow’s—devices.
