In the opening scenes of the new film “Good Night Oppy,” the Opportunity rover rolls along through Perseverance Valley on Mars in June 2018, as “Roam” by The B-52s fills the room at mission control.

The peppy tune was the rover’s wake-up song, played at NASA’s Jet Propulsion Laboratory in Pasadena, California. In the same way NASA has used a song to wake up astronauts each day they spend in space since the 1960s, the Opportunity rover team began their daily shifts with a song that set the mood for “Oppy’s” journey.

But a storm brewing on the horizon changed everything.

Researchers around the world are on a mission to relieve a bottleneck in the clean energy revolution: batteries. From electric vehicles to renewable grid-scale energy storage, batteries are at the heart of society’s most crucial green innovations—but they need to pack more energy to make these technologies widespread and practical.

Now, a team of scientists led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Pacific Northwest National Laboratory (PNNL) has unraveled the complex chemical mechanisms of a battery component that is crucial for boosting energy density: the interphase. Their work published today in Nature Nanotechnology.

It’s not only the gravity from galaxies in a cluster that reveal dark matter, but the ejected, intracluster stars actually trace it out.

The James Webb Space Telescope has finally made its first dark matter observations, and the results could lead us to new physics. They have questioned our understanding of dark matter and the large-scale structure-formation of the Universe. Dark matter is one of the most mysterious entities in the cosmos. Our best cosmological models show that 27% of the observable Universe is made of dark matter. We can’t see it, but its existence can be inferred because of its effect on surrounding baryonic matter. The true nature of dark matter is still one of the biggest mysteries in cosmology. The most successful cosmological model to date, the lambda cold dark matter or the LCDM model, makes a critical prediction regarding dark matter. It says that cold dark matter played an important role to form the large-scale structures we observe today.

So far, we did not have the technology to test this prediction. But the James Webb Space Telescope opened the windows to the first billion years and the last unexplored era in the history of the Universe. The super-early galaxies discovered by Webb in its Early Release Science program provided an opportunity to test the predictions made by the LCDM model. And when astronomers did that, the results were completely unexpected. So what do these primordial galaxies discovered by Webb tell us? What did Webb find in its first dark matter observations? Finally, and most importantly, how can these results change the course of cosmology?

With all the factors that may impact gut health, it can be hard to know what’s causing stomach troubles and potentially affecting long-term wellness.

In a recent TikTok video via Houston Methodist hospital system, gastroenterologist Dr. Neeharika Kalakota shared a few simple rules of thumb she follows to maintain a healthy gut.

As an expert on digestive health, Kalakota said she recommends that her patients stay up-to-date on colon cancer screenings and avoid colonic “cleanses,” which can wreak havoc on the bowel and rectum.

According to a meta-analysis recently published in Neurology, the medical journal of the American Academy of Neurology, higher exposure to a certain type of traffic-related air pollution known as particulate matter may be connected to an increased risk of dementia. Researchers focused on fine particulate matter, or PM_2.5, which is made up of airborne pollutants with a diameter of fewer than 2.5 microns. The meta-analysis examined all available studies on the relationship between air pollution and dementia risk.

“As people continue to live longer, conditions like dementia are becoming more common, so detecting and understanding preventable risk factors is key to reducing the increase of this disease,” said study author Ehsan Abolhasani, MD, MSc, of Western University in London, Canada. “Since a report by the World Health Organization showed that more than 90% of the world population is living in areas with higher than recommended levels of air pollution, our results provide more evidence for enforcing regulations for air quality and accelerating the transition from fossil fuels to sustainable energies.”

17 studies were analyzed by the researchers for the meta-analysis. Participants had a minimum age of 40. More than 91 million individuals took part in all the studies. 5.5 million of them, or 6%, developed dementia.

The animation describes the concept of launching a nuclear fusion reactor into orbit in sections for final assembly in space. The concept uses live footage of Pulsar’s existing hall effect plasma thrusters (HET) and hybrid rocket engines tested at RAF Westcott in March 2022. Pulsar is also developing LOX / Methane rocket motors to support this concept.

China has set up over 100 illegal police stations abroad. They have been tasked with policing the Chinese community, and threatening dissidents to return home. A lot of these police stations are in the West, but the Western govts are silent. Are they scared of China? Priyanka Sharma tells you.

ChatGPT is amazing. It really is.

It can write romantic poems, summarize complex text, provide engaging fun conversations, and answer sophisticated general knowledge questions. It can also produce a fake report for your boss of what you’ve (supposedly) been working on for the last few days — complete with perfectly (surface) plausible code snippets! It makes up stuff.

So could ChatGPT replace human agents in a contact center?
