An anonymous reader shares The Guadian report: Scientists say they have found the world's oldest fossils, thought to have formed between 3.77bn and 4.28bn years ago. Comprised of tiny tubes and filaments made of an iron oxide known as haematite, the microfossils are believed to be the remains of bacteria that once thrived underwater around hydrothermal vents, relying on chemical reactions involving iron for their energy. If correct, these fossils offer the oldest direct evidence for life on the planet. And that, the study's authors say, offers insights into the origins of life on Earth. "If these rocks do indeed turn out to be 4.28 [bn years old] then we are talking about the origins of life developing very soon after the oceans formed 4.4bn years ago," said Matthew Dodd, the first author of the research from University College, London. With iron-oxidising bacteria present even today, the findings, if correct, also highlight the success of such organisms. "They have been around for 3.8bn years at least," said the lead author Dominic Papineau, also from UCL.

New submitter mendred quotes a report from Mashable: Celestine Omin, a software engineer at Andela -- a tech startup that connects developers in Africa with U.S employers -- had a particularly unwelcoming reception when he deplaned at John F. Kennedy Airport and was given a test to prove he was actually a software engineer. A LinkedIn post detailing Omin's challenging experience explained that upon landing in New York after spending 24 miserable hours on a Qatar Airways flight, he was given some trouble about the short-term visa he obtained for his trip. According to the post, an unprepared and exhausted Omin waited in the airport for approximately 20 minutes before being questioned by a Customs and Border Protection officer about his occupation. After several questions were asked, he was reportedly brought to a small room and told to sit down, where he was left for another hour before another customs officer entered and resumed grilling him. Omin was instructed to answer the following questions: "Write a function to check if a Binary Search Tree is balanced," and "What is an abstract class, and why do you need it."

An anonymous reader quotes a report from Reuters: The Trump administration does not want to reform an internet surveillance law to address privacy concerns, a White House official told Reuters on Wednesday, saying it is needed to protect national security. The announcement could put President Donald Trump on a collision course with Congress, where some Republicans and Democrats have advocated curtailing the Foreign Intelligence Surveillance Act, or FISA, parts of which are due to expire at the end of the year. The FISA law has been criticized by privacy and civil liberties advocates as allowing broad, intrusive spying. It gained renewed attention following the 2013 disclosures by former National Security Agency contractor Edward Snowden that the agency carried out widespread monitoring of emails and other electronic communications. Portions of the law, including a provision known as Section 702, will expire on Dec. 31 unless Congress reauthorizes them. Section 702 enables two internet surveillance programs called Prism and Upstream, classified details of which were revealed by Snowden. Democratic and Republican lawmakers have said reforms to Section 702 are needed, in part to ensure the privacy protections on Americans are not violated. The U.S. House of Representatives' Judiciary Committee met Wednesday to discuss possible changes to the law.
