Experts: In Self-Driving Cars, Human Drivers and Standards Come Up Short

All, News, Technology
Autonomous cars should be required to meet standards on their ability to detect potential hazards, and better ways are needed to keep their human drivers ready to assume control, U.S. auto safety and technology experts said after fatal crashes involving Uber Technologies and Tesla vehicles. Automakers and tech companies rely on human drivers to step in when necessary with self-driving technology. But in the two recent crashes, which involved vehicles using different kinds of technologies, neither of the human drivers took any action before the accidents. Driverless cars rely on lidar, which uses laser light pulses to detect road hazards, as well as sensors such as radar and cameras. There are not, however, any standards on the systems, nor do all companies use the same combination of sensors, and some…

New Gene Editing Tool May Yield Bigger Harvests

All, News, Technology
Bread and chocolate are staples of the American diet. And a scientific team in California is working hard to make sure the plants they’re made from are as robust as possible. They’re using a recently discovered bacterial gene-editing tool called CRISPR to create more pest-resistant crops. CRISPR is a feature of the bacterial defense system. The microbes use it like a molecular pair of scissors, to precisely snip out viral infections in their DNA. Scientists at the Innovative Genomics Institute in Berkeley, California, are using CRISPR to manipulate plant DNA. Managing director, Susan Jenkins, says the technique is so much faster and precise than other plant transformation methods, it will likely increase the speed of creating new plant varieties by years, if not decades. “What CRISPR is going to allow,”…

Asian Markets Move Lower After US Stock Plunge

All, Business, News
Stock markets in Asia fell Tuesday, but did not suffer losses as steep as those Monday in U.S. markets where continued fears about a U.S.-China trade war and a verbal attack on an online retailer by President Donald Trump sent stocks lower. Markets in Japan and Hong Kong fell by more than one percent in early trading, but by midday had rebounded to make back half the losses. The U.S. Down Jones Industrial Average closed down 1.9 percent Monday, while the Standard & Poor's 500 dropped 2.3 percent and the NASDAQ fell nearly three percent. Trump has strongly criticized online giant Amazon three times in the last few days. Amazon founder Jeff Bezos also owns The Washington Post, whose revelatory stories on Trump and his administration frequently draw the president's…

US vs. China: a ‘Slap-Fight,’ Not a Trade War — So Far

All, Business, News
First, the United States imposed a tax on Chinese steel and aluminum. Then, China counterpunched Monday with tariffs on a host of U.S. products, including apples, pork and ginseng.  On Wall Street, the stock market buckled on the prospect of an all-out trade war between the world's two biggest economies. But it hasn't come to that - not yet, anyway. "We're in a trade slap-fight right now,'' not a trade war, said Derek Scissors, resident scholar and China specialist at the conservative American Enterprise Institute. China is a relatively insignificant supplier of steel and aluminum to the United States. And the $3 billion in U.S. products that Beijing targeted Monday amount to barely 2 percent of American goods exported to China. But the dispute could escalate, and quickly. Already, in…

Library Helps ‘Left-behind’ Nepali Women Gain Cash, Confidence

All, Business, News
For farmers trying to figure out how to heal a sick cow or grow tomatoes commercially in this Himalayan community, help is at hand in the form of a crumbling, earthquake-scarred library. In a rural area where searching for information online or paying for expert advice is rarely an option, the library is a first stop for female farmers daunted by their new role: running the family farm while their husbands are away looking for work. "Most of the men have migrated for money now in Nepal. It's a very huge problem," said Meera Marahattha, the "human Google" who runs the library. But there's an upside. "Because of this male migration, females have the opportunity to lead," she added - sometimes for the first time. Migration is growing around the…

Facebook Faces Calls to Further Protect User Privacy

All, News, Technology
Facebook is a company in a hurry.   Since the world learned about the latest customer data controversy at Facebook, the social media network has unleashed a swarm of changes. But it’s unclear whether Facebook’s own reckoning will be enough to satisfy regulators and lawmakers.   “We've reached a tipping point with Facebook and privacy,” said Marc Rotenberg, president of the Electronic Privacy Information Center, a public interest advocacy group. “What's most interesting at this moment are the number of forces — political, economic and social — that are converging. And I think the practical consequences is that something big will change.”   With more than 2 billion customers, Facebook has been in the hot seat in recent weeks over how an outside researcher gave the data of 50 million users to…

Amazon Shares Fall 4 Percent as Trump Renews Attack

All, News, Technology
Shares of Amazon.com Inc fell 4 percent on Monday after U.S. President Donald Trump again attacked the online retailer over the pricing of its deliveries through the United States Postal Service and promised unspecified changes. "Only fools, or worse, are saying that our money losing Post Office makes money with Amazon," Trump tweeted. "They lose a fortune, and this will be changed. Also, our fully tax paying retailers are closing stores all over the country ... not a level playing field!" Trump has been vocal about his opposition to Amazon's use of the postal service and Monday's tweet adds to investor worries that the company could see more regulation. Amazon did not immediately respond to requests for a comment. Details of Amazon's payments to the U.S. Postal Service (USPS) are…

Promises, Promises: Facebook’s History with Privacy

All, News, Technology
"We've made a bunch of mistakes." "Everyone needs complete control over who they share with at all times." "Not one day goes by when I don't think about what it means for us to be the stewards of this community and their trust."   Sound familiar? It's Facebook CEO Mark Zuckerberg addressing a major privacy breach — seven years ago.   Lawmakers in many countries may be focused on Cambridge Analytica's alleged improper use of Facebook data, but the social network's privacy problems back more than a decade.

China Raises Tariffs on US Pork, Fruit in Trade Dispute

All, Business, News
China raised import duties on a $3 billion list of U.S. pork, fruit and other products Monday in an escalating tariff dispute with President Donald Trump that companies worry might depress global commerce. The Finance Ministry said it was responding to a U.S. tariff hike on steel and aluminum that took effect March 23. But a bigger clash looms over Trump's approval of possible higher duties on nearly $50 billion of Chinese goods in a separate argument over technology policy. The tariff spat is one aspect of wide-ranging tensions between Washington and Beijing over China's multibillion-dollar trade surplus with the United States and its policies on technology, industry development and access to its state-dominated economy. Forecasters say the immediate impact should be limited, but investors worry the global recovery might…
