A young planet named HIP 67522 causes violent eruptions on its star, dramatically accelerating the loss of its own atmosphere.

Strange planet discovered that causes plasma explosions on its parent star

>Because the planet’s orbit is just seven days long, the gravitational forces from this orbital path tug at the star until plasma erupts from the surface...Heat causes the air to swell, increasing the cross‑section that stellar ultraviolet rays can hit, and leading to a vicious cycle that accelerates mass loss.

>If the current pace holds, HIP 67522 b could shed enough hydrogen and helium to shrink into a mini‑Neptune within 100 million years.

>It may even become a bare, rocky core after that. Such transformations explain why many mature planetary systems harbor small sub‑Neptunes while very close giant planets are rarer.

>Similar run‑away erosion may have sculpted planets like CoRoT‑7 b, where today only a scorched super‑Earth remains...

Greenland’s ice-covered landscape looks like an immovable block on satellite maps. Yet the story beneath its center suggests a different past

Fossil discovery in Greenland ice stuns and worries scientists: "Don't buy a beach house"

>“We now have direct evidence that not only was the ice gone, but that plants and insects were living there,”...Near‑complete melting of Greenland’s ice over the next centuries to a few millennia would lead to some 23 feet of sea‑level rise.

Powell confirms that the Fed would have cut by now were it not for tariffs
  • The tariffs directly cause prices to go up. The inflation-like effect isn't caused by too-rapid growth of currency supply, so lowering the currency supply growth rate & decoupling it from productivity growth risks stagflation . . . unless productivity growth itself is negatively impacted by tariffs, which if true would be repudiation of using tariffs alone as a strategy for growing domestic production.

    >Defining the minimal genetic requirements for cellular life remains a fundamental question in biology...Here, we report the discovery of Candidatus Sukunaarchaeum mirabile, a novel archaeon with an unprecedentedly small genome of only 238 kbp —less than half the size of the smallest previously known archaeal genome...lacking virtually all recognizable metabolic pathways, and primarily encoding the machinery for its replicative core: DNA replication, transcription, and translation. This suggests an unprecedented level of metabolic dependence on a host, a condition that challenges the functional distinctions between minimal cellular life and viruses...

    Controlling diverse robots by inferring Jacobian fields with deep networks

    >Conventional robots can easily be modeled as rigid links connected by joints, but it remains an open challenge to model and control biologically inspired robots that are often soft or made of several materials, lack sensing capabilities and may change their material properties with use. Here, we introduce a method that uses deep neural networks to map a video stream of a robot to its visuomotor Jacobian field (the sensitivity of all 3D points to the robot’s actuators). Our method enables the control of robots from only a single camera, makes no assumptions about the robots’ materials, actuation or sensing, and is trained without expert intervention by observing the execution of random commands...Because it enables robot control using a generic camera as the only sensor, we anticipate that our work will broaden the design space of robotic systems and serve as a starting point for lowering the barrier to robotic automation.

  • Is “required to be demolished” a bad sign?
  • Floor 2 is a fucking mystery. Its too low to walk around the perimeter, but they didn't install a floor in the middle. There's not enough room for insulation between the sun-beaten roof and the living space, but that might be less of an issue because of the huge holes in the trim letting in a steady flow of outside air. That vaulted ceiling also means the house will lose all its heat in the Winter.

    There's no window or exhaust fan in the bathroom.

    It looks like there are holes in the outside wall where windows could be installed, but there are metal flaps there instead. Best case scenario is there is no wall insulation between those flaps and the interior drywall, getting wet and doing biology.

    Affordable Drugs Are Within Reach
    www.forbes.com Affordable GLP-1 Drugs For Weight Loss Are Within Reach

    Although GLP-1 drugs offer many health benefits, their high cost has created an affordability crisis for patients. With a dose of common sense, we can solve this problem.

    Affordable GLP-1 Drugs For Weight Loss Are Within Reach

    American healthcare is too expensive. This is particularly true of brand-name drugs. Although our nation accounts for 4.2% of the world’s population, we consume 13% of the world’s prescription drugs and pay half of the world’s costs for these products. GLP-1 drugs are a case in point...Drug companies need FDA approval before they can market a newly patented drug. Unlike other countries, the FDA can’t consider a new medication’s price or the existence of equally effective, lower-cost alternatives in reaching its decision...Once FDA approval is secured, Medicare typically covers the the drug’s cost because it is not allowed to negotiate with drug companies as other countries do...It’s the main reason the U.S. pays far higher prices than other countries...Rather than bankrupt the federal treasury or, alternatively, pass the costs on to states and tens of millions of American families, Congress should focus on lowering costs and improving the value of American healthcare.

    [Combat] Russians shot down one of their own Su-25 jets.
  • Those rockets miss, but the plane in front dropped flares just prior, so the pilot may have believed a heat seeking missile was launched.

    The wing breaks off at the engine. Was the engine hit with a missile?

    Those engines are 50 years old and probably haven't been getting their regular maintenance on account of the 3 day special military operation going a bit over schedule. Maybe unmaintained SU-25s just randomly have their wings fall off sometimes?

    www.sciencealert.com The Center of Our Universe Does Not Exist. A Physicist Explains Why.

    About a century ago, scientists were struggling to reconcile what seemed a contradiction in Albert Einstein's theory of general relativity.

    The Center of Our Universe Does Not Exist. A Physicist Explains Why.

    >It's easy to think about the creation of the Universe like exploding fireworks: Start with a big bang, and then all the galaxies in the Universe fly out in all directions from some central point.

    >But that analogy isn't correct. Not only does it falsely imply that the expansion of the Universe started from a single spot, which it didn't, but it also suggests that the galaxies are the things that are moving, which isn't entirely accurate.

    >It's not so much the galaxies that are moving away from each other – it's the space between galaxies, the fabric of the Universe itself, that's ever-expanding as time goes on. In other words, it's not really the galaxies themselves that are moving through the Universe; it's more that the Universe itself is carrying them farther away as it expands.

    >A common analogy is to imagine sticking some dots on the surface of a balloon. As you blow air into the balloon, it expands. Because the dots are stuck on the surface of the balloon, they get farther apart.

    >Though they may appear to move, the dots actually stay exactly where you put them, and the distance between them gets bigger simply by virtue of the balloon's expansion. ... >The thing we think of as the "center" of the balloon is a point somewhere in its interior, in the air-filled space beneath the surface.

    >But in this analogy, the Universe is more like the latex surface of the balloon. The balloon's air-filled interior has no counterpart in our Universe, so we can't use that part of the analogy – only the surface matters.

    >So asking, "Where's the center of the Universe?" is somewhat like asking, "Where's the center of the balloon's surface?" There simply isn't one. You could travel along the surface of the balloon in any direction, for as long as you like, and you'd never once reach a place you could call its center because you'd never actually leave the surface.

    >In the same way, you could travel in any direction in the Universe and would never find its center because, much like the surface of the balloon, it simply doesn't have one.
