Among the cosmic rays that normally immerse the Earth, scientists say there are too many high-energy positrons, the antimatter counterparts of electrons. Now a group of researchers from the United States, Mexico, Germany, and Poland are attempting to shed light on the mystery, and if they’re right, according to the Institute of Nuclear Physics Polish Academy of Sciences (IFJ PAN), the excess positrons might be “the first particles recorded by humans to be derived from the interaction of dark matter .” In 2008, a probe in our planet’s orbit detected more positrons reaching us than scientists would anticipate. So a large team conducted observations at the recently activated High-Altitude Water Cherenkov Gamma-Ray Observatory in Mexico to see if pulsars were the source of these baffling extra positrons. They analyzed data from two relatively close pulsars around 800 and 900 light years away. These pulsars, Geminga and PSR B0656+14, are “among the strongest sources of cosmic rays in our region of the galaxy,” according to IFJ PAN. Related: Scientists observe light spectrum of antimatter for the first time ever The pulsars, albeit responsible for some of the positrons, contributed too small an amount to account for all the antimatter hitting Earth. Instead, the researchers’ observations bolstered a competing hypothesis IFJ PAN described as much more exotic: the “annihilation or decay or dark matter” could be the origin of the positrons. If the hypothesis is correct – and we won’t know for sure until future observations back it up or not – these perplexing positrons would be the first particles we’ve ever recorded coming from the interaction of dark matter. The journal Science recently published the research . The University of Utah led the international team.

Dreaming of your very own backyard escape? The cozy Escape Pod may be just what you’re looking for. UK-based firm Podmakers designed and crafted the Escape Pod, a cedar shingle-clad prefabricated unit that can be tailored to suit a variety of uses, including garden room and writer’s studio. The spherical unit takes inspiration from nature, from its round organic shape to the extensive use of timber inside and out. Designed to meet local UK planning laws, each 7-square-meter Escape Pod is built offsite in a Gloucestershire workshop and then delivered and installed using a forklift or crane. The pod is elevated half a meter off the ground and can be rotated to optimize natural light and views through European Oak-framed windows. An aircraft-style plug door opens up to a snug adaptable interior outfitted with insulation, electrical wiring, and heating (choice of a wood-burning stove or underfloor heating). “The organic nature of the Escape Pod’s materials contrasts with the engineering employed in its design,” write Podmakers. “To achieve its curved form, the pod’s design exploits innovative CNC milling and making techniques. This enables it to be fabricated with precision in the workshop, entirely from wood. Birch plywood , chosen for its strength and aesthetic qualities, forms the structure. It is exposed internally; from the pod’s framework to the bespoke laminated door hinge.” Related: Archipod’s Spherical Garden Office Pod The base price for the Escape Pod starts at £19,800. Podmakers developed four recommended layouts—garden room, office, snug (bedroom), and work studio—however the pod can be customized to meet different needs. + Podmakers Via ArchDaily Images © Tim Brotherton
