Averages of the Möbius function on shifted primes
17hIt is a folklore conjecture that the M\"obius function exhibits cancellation on shifted primes; that is, $\sum_{p\le X}\mu(p+h) \ = \ o(\pi(X))$ as $X\to\infty$ for any fixed shift $h>0$. We prove the conjecture on average for shifts $h\le H$, provided $\log H/\log\log X\to\infty$. We also obtain results for shifts of prime $k$-tuples, and for higher correlations of M\"obius with von Mangoldt and

Your cells look young for their age, compared to a chimp's
19hMany humans live to see their 80s, some even reach 100. But chimpanzees rarely make it past 50, despite sharing 99% of our genetic code. While modern medicine has added years to human lifespans, a study points to a more ancient explanation why humans are the long-lived primate. Part of the secret to human longevity may lie in chemical changes to our DNA that slowed the rate of aging after human an
Male baboons with female friends live longer
19hOpposite-sex friendships can have non-romantic benefits. And not just for people, but for our primate cousins, too. A 35-year study of 542 baboons finds that males that have close female friends have higher rates of survival. Previous studies have assumed that males befriend females to protect their offspring, or to boost their chances of mating later on. But the new study points to an additional
