 Most of the atoms in your body left the Milky Way on a 'cosmic conveyor belt' long before you were born, new study reveals

New research suggests that most of the atoms within the human body likely spent part of their lives drifting beyond the Milky Way on a cosmic "conveyor belt," before eventually returning to our galaxy.

Anti-USAG-1 therapy for tooth regeneration through enhanced BMP signaling

  Anti-USAG-1 therapy for tooth regeneration through enhanced BMP signaling A Murashima-Suginami   1 ,  H Kiso   1 ,  Y Tokita   2 ,  E Mihara   3 ,  Y Nambu   4 ,  R Uozumi   5 ,  Y Tabata   6 ,  K Bessho   1 ,  J Takagi   3 ,  M Sugai   7   8 ,  K Takahashi   9 Affiliations  Expand PMID:  33579703   PMCID:  PMC7880588   DOI:  10.1126/sciadv.abf1798 Abstract Uterine sensitization-associated gene-1  ( USAG-1 ) deficiency leads to enhanced bone morphogenetic protein (BMP) signaling, leading to supernumerary teeth formation. Furthermore, antibodies interfering with binding of USAG-1 to BMP, but not lipoprotein receptor-related protein 5/6 (LRP5/6), accelerate tooth development. Since USAG-1 inhibits Wnt and BMP signals, the essential factors for tooth development, via direct binding to BMP and Wnt coreceptor LRP5/6, we hypothesized that USAG...

Scientists make disturbing discovery in Miami's rainwater: 'What happens in one area can impact here, there, everywhere'

  Scientists make disturbing discovery in Miami's rainwater: 'What happens in one area can impact here, there, everywhere' Story by Leslie Sattler Rain in Miami has a disturbing secret: It's carrying toxic "forever chemicals" that can harm people and wildlife, per  reports  by Phys.org. These synthetic substances,  known as PFAS , are hitching a ride on raindrops and spreading far beyond their source, according to research from Florida International University. See Full Story here

Boeing Starliner astronauts will return to Earth in March 2025 after new NASA, SpaceX delay

  Boeing Starliner astronauts will return to Earth in March 2025 after new NASA, SpaceX delay By  Josh Dinner That's one month later than previously planned. The astronaut duo who flew the first-ever crewed mission of Boeing's Starliner capsule will have to wait a little longer to rejoin us on  Earth . The next crew rotation mission to the  International Space Station  (ISS), SpaceX's Crew-10, has been delayed to no earlier than late March 2025, NASA announced on Tuesday (Dec. 17). Crew-10 was originally  slated to fly in February , but it has been pushed back to allow time for  SpaceX  to complete work on a brand-new  Crew Dragon  spacecraft for the mission,  NASA  said in  a statement  on Tuesday. The delay means at least an extra month aboard the ISS for the astronauts of SpaceX's Crew-9 flight, who won't depart the orbital laboratory until after Crew-10's arrival.
