Vaccine Refusal Will Come at a Cost—For All of Us
Imagine it's 2026. A man shows up in an emergency room, wheezing. He's got pneumonia, and it's hitting him hard. He tells one of the doctors that he had COVID-19 a few years earlier, in late 2021. He had refused to get vaccinated, and ended up contracting the coronavirus months after most people got their shots. Why did he refuse? Something about politics, or pushing back on government control, o

NASA's Mars Helicopter to make first flight attempt Sunday
NASA's Ingenuity Mars Helicopter is two days away from making humanity's first attempt at powered, controlled flight of an aircraft on another planet. If all proceeds as planned, the 4-pound (1.8-kg) rotorcraft is expected to take off from Mars' Jezero Crater Sunday, April 11, at 12:30 p.m. local Mars solar time (10:54 p.m. EDT), hovering 10 feet (3 meters) above the surface for up to 30 seconds.

How big are the blood-clot risks of the AstraZeneca jab? | David Spiegelhalter and Anthony Masters
For most people, the risks of Covid outweigh the minimal risks from the vaccines Last Wednesday, the European Medicines Agency stated there was a plausible link between the Oxford/AstraZeneca (Vaxzevria) vaccine and rare types of blood clotting, which the MHRA estimates may happen in one in 100,000 young adults who get the vaccine. It is challenging to think of such low risks: when we have to cou

The primitive brain of early Homo

Targeting the nucleotide salvage factor DNPH1 sensitizes BRCA-deficient cells to PARP inhibitors
Mutations in the BRCA1 or BRCA2 tumor suppressor genes predispose individuals to breast and ovarian cancer. In the clinic, these cancers are treated with inhibitors that target poly(ADP-ribose) polymerase (PARP). We show that inhibition of DNPH1, a protein that eliminates cytotoxic nucleotide 5-hydroxymethyl-deoxyuridine (hmdU) monophosphate, potentiates the sensitivity of BRCA -deficient cells t
