SpaceX's next astronaut flight for NASA to include heat shield tweak and more

SpaceX and NASA are preparing for the first full-fledged crew flight to the International Space Station, which will look similar — but not identical — to the crewed test flight the pair ran this summer. That test flight, dubbed Demo-2, saw veteran NASA astronauts ...

Possibility of Dark Bosons Entices Physicists

Scientific American

Physicists are on the hunt for dark forces. These forces are not as ominous as they sound: "dark" simply refers to the fact that no one has observed them before. In this case, they would act between neutrons and electrons. One path to investigating dark forces ...

Time travel is possible based on the laws of physics, according to new calculations from researchers at the University of Queensland. But time-travelers wouldn't be able to alter the past in a measurable way, they say — the future would stay the same.

Developing the fastest and most sensitive graphene microwave bolometer

Bolometers are devices that measure the power of incident electromagnetic radiation thru the heating of materials, which exhibit a temperature-electric resistance dependence. These instruments are among the most sensitive detectors so far used for infrared ...
