Israel: when reality meets academia
On 7 October, thousands of Hamas terrorists invaded southern Israel, killing at least 1,400 people and kidnapping more than 240 civilians. These include fellow faculty members, postdocs and students who are dead, wounded or still missing. Along with many other academics, we have been vocal advocates of greater liberalism in Israel (see E. Albin et…

Nobel win: spotlight on the attrition of women in science
Katalin Karikó’s joint win of this year’s Nobel Prize in Physiology or Medicine helps to redress the history of gender bias in Nobel awards (see Nature 622, 228–229; 2023). Yet her achievement is not so much a win for female researchers as a warning of how much is being lost through the continued attrition of…

Dentinomimetics and cementomimetics of Moringa oleifera leaves extract
Abstract To evaluate the biomimetic remineralization capabilities of Moringa oleifera leaves (MOL) extract on coronal dentin and acellular cementum, two different concentrations (50 and 200 mg/ml) of MOL extract loaded in plain varnish (M1 and M2 groups respectively) were compared to fluoride varnish (FL group) and native surface (C group). Eighty sound premolar teeth were collected.…

How AI could lead to a better understanding of the brain
Can a computer be programmed to simulate a brain? It’s a question mathematicians, theoreticians and experimentalists have long been asking — whether spurred by a desire to create artificial intelligence (AI) or by the idea that a complex system such as the brain can be understood only when mathematics or a computer can reproduce its…

Ligand recognition and G protein coupling of trace amine receptor TAAR1
Abstract Trace amine-associated receptors (TAARs), a group of biogenic amine receptors, play pivotal roles in neurological and metabolic homeostasis1. They recognize diverse endogenous trace amines (ETAs) and subsequently activate a range of G protein subtype signaling pathways2,3. Notably, TAAR1 has emerged as a promising therapeutic target for treating psychiatric disorders4,5. However, the molecular mechanisms underlying…

Croaking Frogs, Buzzing Hornets, Squealing Dolphins: A Guide to Smithsonian Folkways’ Best Science and Nature Recordings
We’re always finding ways to capture and learn from the sounds around us: Recordings of melting ice assist in tracking the rate of climate change; hydrophones eavesdropping on underwater insects help measure the health of the ecosystem; and astronomers even figured out the pitch of a massive black hole—B flat, it turned out—in order to…
