  • South African child remains AIDS free without ongoing drug treatment, researchers say

    A South African child born with HIV has surprised experts by appearing to be effectively cured of the AIDS virus after just a year of treatment, followed by 8½ years drug free. Patients with HIV would normally need to stay on antiretroviral (ART) drugs for the rest of their...
  • How Climate Change Is Already Affecting Earth

    Though the planet has only warmed by one-degree Celsius since the Industrial Revolution, climate change’s effect on earth has been anything but subtle. Here are some of the most astonishing developments over the past few years....
  • Anti-CRISPR proteins decrease off-target side effects of CRISPR-Cas9

    CRISPR-Cas9 gene editing is based on a tactic bacteria developed to protect themselves from viruses.  #Research now shows that the countermeasure viruses came up with — inhibitory proteins referred to as anti-CRISPRs — can be used to improve CRISPR-Cas9 as a gene-therapy tool, decreasing off-target gene editing that could...
  • Emmaus bags FDA approval for sickle cell therapy; now comes the hard part

    An FDA greenlight for sickle cell disease therapy Endari has catapulted its developer, Emmaus Medical, into the spotlight, but commercializing the new drug could be challenging. The approval means the privately-held biotech has ended a 20-year drought in new therapies for sickle cell disease (SCD), an inherited disease in which red...
  • SpaceX delivers for Intelsat on heavyweight Falcon 9 mission

    A SpaceX Falcon 9 rocket rumbled into the sky Wednesday from NASA’s Kennedy Space Center in Florida, flexing the rocket’s muscles and lofting a massive Intelsat satellite to orbit supporting wireless communications, television broadcasting and trans-Atlantic data relays. Recovering from back-to-back countdown aborts earlier in the week, the two-stage,...
  • Incredible New Observation Shows Supermassive Black Holes Orbiting Each Other

    You think our galaxy is special? Ha. Our boring pinwheel of gas and dark matter might be a nice hangout for humans. But 750 or so million light years away, there’s an elliptical galaxy, Galaxy 0402+379, whose two supermassive black holes are orbiting each other from a distance of...
  • Look, kids! Science!

    In my very first Experimental Error column in 2010, I made fun of standard science demonstrations, especially one I called “Let’s All Gawk at Liquid Nitrogen.” Why, I complained, were certain experiments so universal, especially when they showed nothing about what scientists actually do? Now, 7 years and 82...
  • Molecular system for artificial photosynthesis

    Photosystems (PS) I and II are large protein complexes that contain light-absorbing pigment molecules needed for photosynthesis. PS II captures energy from sunlight to extract electrons from water molecules, splitting water into oxygen and hydrogen ions (H+) and producing chemical energy in the form of ATP. PS I uses...
  • 17 Concise Reasons Why Homeopathy is a Fraud

    One can’t help but be perplexed by the bizarre world of #homeopathy . From miracle cures to snake oil peddling, from deceptive advertising to FDA warnings, from questionable medical claims to rigorous scientific testing, it’s an uncanny circle of health declarations and assertions. Here is hopefully a comprehensive overview...
