Curves are attractive
Steps to STIMulation W hen ER calcium levels plummet, an ER membrane calcium sensor called STIM1 directly activates plasma membrane (PM) channels to top up the cell’s calcium. Jen Liou, Tobias Meyer, and colleagues (Stanford University Medical School, Stanford, CA) have now uncovered the molecular steps of STIM1’s pathway to the PM and show that those steps don’t take STIM1 very far. STIM1 sits...

He wrote: “The faces blend in the most remarkable manner, producing in case of some ladies portraits, in every instance, a decided improvement in beauty” (Galt...
متن کاملAttractive Subfamilies of BLS Curves for Implementing High-Security Pairings
Barreto-Lynn-Scott (BLS) curves are a stand-out candidate for implementing high-security pairings. This paper shows that particular choices of the pairing-friendly search parameter give rise to four subfamilies of BLS curves, all of which offer highly efficient and implementationfriendly pairing instantiations. Curves from these particular subfamilies are defined over prime fields that support ...
متن کاملBriefly Glimpsed People are more Attractive
Assessments of attractiveness underlie selection and pursuit of potential mates. Previous research has shown that people are sometimes perceived to be more attractive with a brief glimpse, yet there is no explanation for why this effect might exist. Here, participants rated the attractiveness of males and females photographs, viewed in two conditions: once for 225 ms, and once without time cons...
متن کاملAre web stabilimenta attractive to praying mantids?
Certain species of orb-weavers add extra silk structures, termed a stabilimentum or web decoration, to their webs. In the genus Argiope stabilimenta are silken structures of densely woven zig-zag ribbons. The adaptive value of these stabilimenta is still unclear and controversially discussed. In the course of time, many functional hypotheses have been proposed for silk stabilimenta. Because of ...
