In the past three years, the workplace has changed dramatically.

According to a recent McKinsey survey, 98 million American workers now have the option to perform their jobs remotely. And 77 percent of respondents to a recent Deloitte survey cited greater workplace flexibility as a top reason to switch jobs.

Yet the exact same proportion, 77%, told Deloitte they have felt burnout at their current job. Another study found that about half of the fulltime employees surveyed feel disconnected from their coworkers.

In a new study published in Aging Cell [1], researchers report that transient activation of the Yamanaka factor Oct4 allowed partial reprogramming of cells, which led to rejuvenation in these cells and in a mouse model of premature aging.

The way AI models structure text may have something to do with it, according to the study authors.

Jodhpur couple Rajnush and Vedika Agarwal have turned their ancestral land into an experiential farm named MharoKhet, where they not only grow several organic exotic vegetables, but also deliver the freshest produce within hours of harvest.

Engineers from Rice University and the University of Maryland have created full-motion video technology that could potentially be used to make cameras that peer through fog, smoke, driving rain, murky water, skin, bone and other media that reflect scattered light and obscure objects from view.

“Imaging through scattering media is the ‘holy grail problem’ in optical imaging at this point,” said Rice’s Ashok Veeraraghavan, co-corresponding author of an open-access study published today in Science Advances. “Scattering is what makes light—which has lower wavelength, and therefore gives much better spatial resolution—unusable in many, many scenarios. If you can undo the effects of scattering, then imaging just goes so much further.”

Undeterred after three decades of looking, and with some assistance from a supercomputer, mathematicians have finally discovered a new example of a special integer called a Dedekind number.

Only the ninth of its kind, or D, it is calculated to equal 286 386 577 668 298 411 128 469 151 667 598 498 812 366, if you’re updating your own records. This 42 digit monster follows the 23-digit D discovered in 1991.

Grasping the concept of a Dedekind number is difficult for non-mathematicians, let alone working it out. In fact, the calculations involved are so complex and involve such huge numbers, it wasn’t certain that D would ever be discovered.

Monday’s test firing of Ship 25 seems to have gone resoundingly well. On Tuesday afternoon (June 27), SpaceX tweeted images from the previous day’s proceedings, and they highlight the sheer power generated by Starship’s engines. The smoke and dust from ignition managed to stay low enough to the ground, and diffuse enough, for Starship to remain perfectly in frame, engine fire imparting an orange glow to the black tiles of the vehicle’s heat shield.

SpaceX founder and CEO Elon Musk also tweeted an image from the static-fire test early on Tuesday morning. This one, from an upward perspective, shows the extreme bright light emanating from the flames, with Starship centered in the shine.

A robot fish named Belle could be the “spy on the marine life” that researchers have been looking for.

This isn’t the first time NASA has encouraged the public to add their names to objects bound for space, including those aboard Artemis I, as well the Preservation Rover and InSight on their multiple trips to Mars. In 1977, Voyager 1 and 2 both launched with gold-plated phonographic records aboard featuring 90 minutes of music, including a concerto by Bach and Chuck Berry’s “Johnny B. Goode.”

At the time of writing, over 305,000 people from nearly every nation across the world have already signed the Europa Clipper’s roster, and earthbound participants have until the end of 2023 to enter in their names. Until then, you can also tune into regular livestreams of the Europa Clipper’s construction and assembly.
