Take a moment to stare into thousands of never-before-seen young stars in the Tarantula Nebula. Webb reveals details of the structure and composition of the nebula, as well as background galaxies

The Tarantula Nebula gets its name from its dusty filaments. The largest and brightest star-forming region near our galaxy, it's home to the hottest, most massive stars known! This nebula lets us see what star formation might have looked like at its peak in our cosmic history.

2022-09-06 15:02:00 Finally! There's Now a Way to Send Text Messages on Your Phone Underwater

You may not have given much thought to being able to text underwater, but for millions of scuba diving and snorkeling enthusiasts, communication in the ocean is pretty essential to staying safe.

"Other than downloading an app to their phone, the only thing people will need is a waterproof phone case rated for the depth of their dive," says Chen.

That app is AquaApp, and it can work with speakers and microphones on ordinary smartphones – or even smartwatches. It gives users 240 preset messages to pick from, split into eight categories for easier access.

In tests in a variety of scenarios, the team found the app was effective at communicating messages across a distance of 30 meters (98 feet). For shorter-length messages – emergency SOS messages, for example – the app can go up to 100 meters (nearly 330 feet). This is all managed without a huge drain on battery life.

2022-09-05 21:54:39 Cannabis users no more likely to lack motivation than non-users: Study breaks 'stoner' stereotype

Adult and adolescent cannabis users are no more likely than non-users to lack motivation or be unable to enjoy life's pleasure, new research has shown, suggesting there is no scientific basis for the stereotype often portrayed in the media.

Cannabis users also show no difference in motivation for rewards, pleasure taken from rewards, or the brain's response when seeking rewards, compared to non-users.

2022-09-05 08:01:48 NASA unsure next Moon rocket launch attempt possible this month

After scrapping a second attempt to get its new 30-story lunar rocket off the ground due to a fuel leak, NASA officials said Saturday it may not be possible to try again this month.

The current launch window for NASA's Artemis 1 mission to the Moon ends Tuesday and is "definitely off the table," said Jim Free, associate administrator for Exploration Systems Development, at a press conference Saturday.

The next possible launch window is September 19 to October 4, and failing that, October 17 to 31, NASA said.

The ability to take off during those windows "will really depend on the options that the team comes back with likely on Monday or early Tuesday morning," said Free.

2022-09-04 20:00:42 New method eradicates deadly brain tumors by 'starving' them of energy source

A groundbreaking study at Tel Aviv University effectively eradicated glioblastoma, a highly lethal type of brain cancer.

The researchers achieved the outcome using a method they developed based on their discovery of two critical mechanisms in the brain that support tumor growth and survival: one protects cancer cells from the immune system, while the other supplies the energy required for rapid tumor growth. The work found that both mechanisms are controlled by brain cells called astrocytes, and in their absence, the tumor cells die and are eliminated.

The researchers explain, "Glioblastoma is an extremely aggressive and invasive brain cancer, for which there exists no known effective treatment. The tumor cells are highly resistant to all known therapies, and, sadly, patient life expectancy has not increased significantly in the last 50 years. Our findings provide a promising basis for the development of effective medications for treating glioblastoma and other types of brain tumors."

2022-09-04 11:01:55 Scientists Just Found a New Kind of Synapse Hiding in The Brains of Mice

A previously unknown type of synapse appears to have been hiding in strange, hair-like appendages that can be found on the surfaces of neurons, new research reveals.

A study in mice suggests that structures called primary cilia play a role in neuronal signaling; specifically, they act as a shortcut for transmitting signals directly into the nucleus to trigger changes to chromatin, the complex that forms chromosomes.

This discovery may help scientists unravel the role of these mysterious structures in other cells, as well as give us a deeper understanding of the complicated workings of the brain.

2022-09-04 04:01:32 SU(N) matter is about 3 billion times colder than deep space

A Kyoto team led by study author Yoshiro Takahashi used lasers to cool its fermions, atoms of ytterbium, within about one-billionth of a degree of absolute zero, the unattainable temperature where all motion stops.

That's about 3 billion times colder than interstellar space, which is still warmed by the afterglow from the Big Bang.

"Unless an alien civilization is doing experiments like these right now, anytime this experiment is running at Kyoto University it is making the coldest fermions in the universe," said Rice University's Kaden Hazzard

"The payoff of getting this cold is that the physics really changes," Hazzard said. "The physics starts to become more quantum mechanical, and it lets you see new phenomena."

2022-09-04 01:51:51 Years after shuttle, NASA rediscovers the perils of liquid hydrogen

‍A more in-depth overview of today's scrub, the road ahead for the SLS rocket, and the smallest element in the universe.

NASA sought to launch a rocket largely cobbled together from the space shuttle, which itself was designed and built more than four decades ago.

As the space shuttle often was delayed due to technical problems, it therefore comes as scant surprise that the debut launch of NASA's Space Launch System rocket scrubbed a few hours before its launch window opened...

2022-09-04 00:25:53 SLS Update Continued

NASA Administrator Bill Nelson says the Artemis 1 mission management team will determine whether to make another launch attempt Monday or Tuesday, or roll the Space Launch System moon rocket back to the Vehicle Assembly Building for repairs and re-testing.

If the rocket has to return to the VAB, the Artemis 1 launch will be delayed to October. The next launch period opens Sept. 19 and closes Oct. 4, but it's more likely that the flight would be pushed back to a launch period opening Oct. 17.

"We'll go when we're ready," Nelson said. "This is part of our space program -- be ready for scrubs."

The Artemis 1 launch team has entered into a 48-hour countdown recycle to preserve the chance to try another launch attempt as soon as Monday.
