Arizona death brings calls for more autonomous vehicle rules
The deadly collision between an Uber autonomous vehicle and a pedestrian near Phoenix is bringing calls for tougher self-driving regulations. Police in Tempe, Arizona, say the female pedestrian walked in front of the Uber SUV Sunday night. Current federal regulations have few requirements specifically for self-driving vehicles, leaving it for states to handle. Many federal and state officials say their regulations are sufficient to keep people safe while allowing the potentially life-saving technology to grow.

Agriculture must make water use go further: experts
In a world where water risks running short for many, the especially thirsty agricultural industry must learn how to manage the vital resource better, experts said Tuesday. A day after the United Nations warned that 5.7 billion people could be short of drinking water by 2050, experts said agriculture faces its own threat. Technology is helping to transform irrigation, with drones, computerized irrigation systems, data and satellites playing their part, speakers said at the 8th World Water Forum, an international gathering of water experts.
Test reveals why female lion in Oklahoma zoo sprouted a mane
Lab results have revealed the answer to a mystery at an Oklahoma zoo: Just what caused a female lion to sprout a mane. Veterinarians compared Bridget's blood to samples from her sister, who has no mane. Bridget's blood also contained a higher level of cortisol, which regulates metabolism and the immune system. The zoo says the results likely mean the 18-year-old lioness has a benign tumor that's producing the hormones, but that her health is excellent.
EU lawmakers, UK regulator press Facebook on data breach
Committee chairman Damian Collins said Facebook officials had consistently understated the risk of data being taken from users without consent. EU Justice Commissioner Vera Jourova, who has called the breach horrifying, will meanwhile seek clarification from Facebook during a visit to the United States this week. US lawmakers have already called on Zuckerberg to appear before Congress, along with the chief executives of Twitter and Google.
Airbus to name new CEO at end of year: company
European aviation giant Airbus said Tuesday it will name a successor to departing CEO Tom Enders at the end of 2018. France-based Airbus in December announced that Enders, who is German, would not seek reappointment when his current term runs out out next year. It has also faced challenges with the A380 superjumbo, the world's largest civilian airliner, as well as over-budget military transporter A400M. In early March it announced plans to cut around 3,700 jobs on the A380 and A400M programmes.

Ministers suffer nuclear defeats in Lords
The government has been defeated twice in the House of Lords over its plans for nuclear co-operation after Brexit. Peers voted by 265 to 194 to insist the UK should not withdraw from the European nuclear agreement, Euratom, until a replacement deal is in place. MPs are likely to try and overturn the changes to the Nuclear Safeguards Bill when it returns to the Commons.
Marine researchers say recent sea star wasting disease epidemic defies prediction
Beginning in 2013, a mysterious disease crippled sea star populations up and down the US west coast. Over a matter of months, many sea star species died in record-breaking numbers, though Pisaster ochraceus-a keystone species known as the ochre sea star-was among the hardest hit. Scientists aren't sure what causes this disease, known as sea star wasting syndrome (SSWS). Another factor that researchers consider when trying to predict the spread of a disease is the density of the affected populations in different areas.
What plants can teach us about oil spill clean-up and microfluidics
For years, scientists have been inspired by nature to innovate solutions to tricky problems, even oil spills-manmade disasters with devastating environmental and economic consequences. A new USC study takes a cue from leaf structure to fabricate material that can separate oil and water, which could lead to safer and more efficient oil spill clean-up methods. Droplet-based microfluidics is a tool used in various applications like cell cultures, chemical synthesis and DNA sequencing.
First population-scale sequencing project explores platypus history
They were able to establish a platypus family history and kinship in a level of detail not previously sampled. We have described the first population-scale, whole-genome sequencing study of the platypus, said Dr Peter Donnelly from Oxford. The research team was also able to estimate vital evolutionary forces at work including platypus mutation rates, divergence times, and population sizes throughout its history. With the new genome data in hand, future studies will continue to explore the population history and unique biology of the platypus.
A method for predicting the impact of global warming on disease
Scientists have devised a method for predicting how rising global temperatures are likely to affect the severity of diseases mediated by parasites. Their method can be applied widely to different host-pathogen combinations and warming scenarios, and should help to identify which infectious diseases will have worsened or diminished effects with rising temperatures. Professor Luijckx said: Rising temperatures due to global warming can alter the proliferation and severity of infectious diseases, and this has broad implications for conservation and food security.
Google buys NYC's Chelsea Market building for $2.4 bn
Google on Tuesday bought up New York's Chelsea Market for $2.4 billion, finalizing its acquisition of the emblematic retail and food hall that stands opposite the internet giant's current headquarters in the city. Google had already paid $1.7 billion for the building facing the market in 2010, which has 275,000 square metres of office floorspace. The building sold for $280 million in 2003, and in 15 years its value has increased eightfold, reflecting the meteoric rise in the city's property prices.
Foxconn selects general contractor, engineering consultants
