Ny 3D-karta över universum: ”Einstein kan ha haft fel”
En ny 3D-karta över universum visar över 47 miljoner galaxer. Kartan är den mest detaljerade som någonsin gjorts – och kan tvinga forskare att tänka om kring Einstens teorier. – Hans teori har testats extremt väl, men kanske händer något annat när vi ser på hela kosmos, säger forskaren Klaus Honscheid, som varit involverad i projektet.
Stateside with Kai and Carter: why the fight over abortion pills is only just beginning – podcast

En stor utmaning har varit att få immunförsvaret att bilda så kallade brett neutraliserande antikroppar som kan känna igen delar av viruset som är gemensamma för många olika hiv-varianter.
