Stop Opera’s New VPN from Leaking Your IP Address

by Alan Henry

Last week, Opera added a VPN to the dev version of its browser , which was certainly good news. The bad news is that unlike the more robust VPNs it tries to replace, it leaks data that should be encrypted all over the place, namely your private IP address. Here’s how to fix it.

[Feature] Who's downloading pirated papers? Everyone

by John Bohannon
In increasing numbers, researchers around the world are turning to Sci-Hub, the controversial website that hosts 50 million pirated papers and counting. Now, with server log data from Alexandra Elbakyan, the neuroscientist who created Sci-Hub in 2011 as a 22-year-old graduate student in Kazakhstan, Science addresses some basic questions: Who are Sci-Hub's users, where are they, and what are they reading? The Sci-Hub data provide the first detailed view of what is becoming the world's de facto open-access research library. Among the revelations that may surprise both fans and foes alike: Sci-Hub users are not limited to the developing world. Some critics of Sci-Hub have complained that many users can access the same papers through their libraries but turn to Sci-Hub instead—for convenience rather than necessity. The data provide some support for that claim. Over the 6 months leading up to March, Sci-Hub served up 28 million documents, with Iran, China, India, Russia, and the United States the leading requestors. Author: John Bohannon

This Retirement Calculator Tells You How Much to Save Monthly to Reach Your Goal

by Kristin Wong on Two Cents, shared by Andy Orin to Lifehacker

Saving for retirement seems overwhelming, and a big part of that is it’s just so much money . For example, if you’re 40, you’re supposed to have twice your annual salary saved. If you’re starting late, that might seem impossible. Like all goals, it helps to start small , and NerdWallet’s new retirement calculator helps you do just that.

Total Syntheses of Periconiasins A–E

by Chong Tian, Xiaoqiang Lei, Yuanhao Wang, Zhen Dong, Gang Liu, Yefeng Tang

Abstract

The first and collective total syntheses of periconiasins A–E, a group of naturally occurring cytochalasans, were achieved by a series of rationally designed or bioinspired transformations. Salient features of the syntheses include a tandem aldol condensation/Grob fragmentation to assemble the linear polyketide–amino acid hybrid precursor, a Diels–Alder macrocylization to construct the 9/6/5 tricyclic core of periconiasins A–C, and a transannular carbonyl–ene reaction to forge the polycyclic framework of periconiasins D and E.

Family members: The collective total syntheses of periconiasins A–E, a group of newly identified cytochalasans, are presented. An array of rationally designed or bioinspired transformations, including a tandem aldol condensation/Grob fragmentation, a Diels–Alder, and a transannular carbonyl–ene reaction allows rapid access to the targets from readily accessible building blocks.

Transfer of Electrophilic NH Using Convenient Sources of Ammonia: Direct Synthesis of NH Sulfoximines from Sulfoxides

by Marina Zenzola, Robert Doran, Leonardo Degennaro, Renzo Luisi, James A. Bull

Abstract

A new system for NH transfer is developed for the preparation of sulfoximines, which are emerging as valuable motifs for drug discovery. The protocol employs readily available sources of nitrogen without the requirement for either preactivation or for metal catalysts. Mixing ammonium salts with diacetoxyiodobenzene directly converts sulfoxides into sulfoximines. This report describes the first example of using of ammonia sources with diacetoxyiodobenzene to generate an electrophilic nitrogen center. Control and mechanistic studies suggest a short-lived electrophilic intermediate, which is likely to be PhINH or PhIN+.

Thumbnail image of graphical abstract

Making a transfer: Convenient reagents for NH transfer allow the direct preparation of NH sulfoximines from sulfoxides. A wide range of diversely functionalized sulfoximines are prepared in high yields using simple ammonium salts with a hypervalent iodine reagent. Evidence is provided for a short-lived reactive species (see scheme).

[Editorial] My love-hate of Sci-Hub

by Marcia McNutt
Like many scientist-editors of journals published by nonprofit scientific societies, I have a love-hate relationship with Sci-Hub, the website operated out of Russia that provides access to 50 million pirated scientific articles to researchers worldwide (see the News story on p. 508). I recognize the underlying motivation of bringing global research content to the developing world. However, I also recognize that much traffic to Sci-Hub is from researchers who already have access to the articles they seek through mechanisms such as site licenses, open access, or other means. Authors who publish in Science journals, for example, can make their papers available immediately upon publication through free referrer links at the authors' websites. Research published after 1996 in a Science journal is made free with registration 1 year after its publication date. So what does the scientific community risk by gathering papers illegally?
