Orion’s Twin Rogue Planets Inexplicably Blaze with Intense Radio WavesResearchers don’t know how this pair of free-floating planets formed or why it radiates so brightlyBy Joseph HowlettPart of the Orion Nebula shown in infrared.

Pearson (CC BY-SA 3.0 IGO)Strange, twirling duos of roughly Jupiter-size celestial bodies in the Orion Nebula have had astronomers scratching their heads since the James Webb Space Telescope (JWST) photographed them in…

Sea-surface readings at the Leigh Marine Laboratory north of Auckland since that time indicate the "unprecedented nature of recent marine…

The breaking of orographic gravity waves induces a zonal wave drag in the middle troposphere, which destroys the geostrophic balance of the large-scale westerly flow and thus drives an ageostrophic meridional circulation across the Tibetan Plateau. The rising branch of the meridional circulation acts to lower the pressure and increase the meridional pressure gradient to the south of the Tibetan Plateau by dynamically pumping the lower-tropospheric air…

While you're peacefully dreaming, your brain is taking care of a few important maintenance tasks. A new study reveals more about the process that ejects waste material from the brain while we're snoozing.The brain produces these waste substances as it expends energy and sucks up nutrients during the day. Taking out the trash is the job of the glymphatic system, however we don't yet have a full picture of how this network of drainage channels functions.Researchers from Washington University in St Louis observed neurons…

The paper, which is published in the open access journal Weather and Climate Dynamics, suggests that European summer weather is predictable…

There are several instant messaging apps available, such as WhatsApp, Telegram, and others. However, one app that prioritizes user privacy is Signal. And now, Signal is upping the game by adding usernames, so if you don’t like sharing your phone number with people, you’ll love this. However, the feature is in the beta version and is yet to roll out for others. Signal is introducing usernames Signal will let you pick a unique username that you can share with others and initiate conversations. Once the feature rolls out to…

A mug of hot chocolate left to sit for a while in a cold room isn't going to warm your belly.But new research shows that if left in an even colder room, one virtually devoid of heat altogether, your cup of delicious cocoa will be hot again in no time.Researchers from the Massachusetts Institute of Technology in the US and Swinburne University of Technology in Australia discovered a bizarre thermodynamic phenomenon of rebounding heat waves emerging in materials known as superfluids.While it's not in any way a practical…
