Conventional surveys can’t track migration after natural disasters in real time. But Facebook data may provide a crude estimate of those who flee.

A new technique for locating land mines uses infrared cameras on drones. The novel technology uses temperature differences to find camouflaged mines before anyone might accidentally step on them.

Quantum physicist Paul Kwiat reveals what it takes do well in LabEscape, his science-themed escape room.

The US Defense Advanced Research Projects Agency (DARPA) is eyeing flight tests later this year for two hypersonic weapons, and it is teaming up with the US Army on developing such a ground-launched capability. However, at the same time, army leaders are drafting plans to consolidate duelling lines of effort within their hypersonic weapons’ portfolio.

During a 1 May Defense Writers’ Group breakfast with reporters, DARPA Director Dr Steven Walker fielded questions about ongoing projects inside the Pentagon’s research arm including the development of two hypersonic weapons with the US Air Force (USAF) — the Tactical Boost Glide (TBG) and the Hypersonic Air-breathing Weapon Concept (HAWC).

“[They are] two very different concepts but when you’re talking hypersonic [weapons], it is good to have what I consider intended redundancy because it’s a hard technology, making materials and propulsion systems that last in 3,000° Fahrenheit temperatures is not easy,” Walker said.

• When Uber goes public next week, some early investors in the ride-hailing company stand to make handsome profits.
• Jeff Bezos is among that group — his $3 million stake could be worth $400 million at IPO time.
• Ousted founder and CEO Travis Kalanick is expected to make nearly $9 billion from his 8.6 percent stake.

The rich keep getting richer. Amazon founder and CEO Jeff Bezos, whose estimated net worth of $157 billion makes him the richest man in the world, is expected to haul in hundreds of millions of dollars from Uber’s anticipated initial public offering next week.

Many other countries have already banned the products. But the U.S. agency said the risk was still low, despite repeated requests from women and doctors that the implants be removed from the market.

If you take a look at the life of freshwater shrimp in the sleepy English countryside, you’ll find enough drugs to keep a funk band on tour very happy.

A new study has found notable levels of cocaine, ketamine, Valium, Xanax, t ramadol, and other pharmaceuticals in the bodies of freshwater shrimp and their habitat in Suffolk, UK. The researchers also found traces of numerous pesticides that are now banned by the EU.

Reporting in the journal Environment International, scientists from King’s College London analyzed levels of micropollutants in surface water samples and Gammarus pulex freshwater shrimp from 15 different sites across the county of Suffolk in the east of England. To their surprise, they discovered trace levels of at least 67 different contaminant compounds. The most frequently detected contaminant was cocaine, which was detected in every single shrimp from all 15 sites.

An end to the AIDS epidemic could be in sight after a landmark study found men whose HIV infection was fully suppressed by antiretroviral drugs had no chance of infecting their partner.

The success of the medicine means that if everyone with HIV were fully treated, there would be no further infections.

Among nearly 1,000 male couples across Europe where one partner with HIV was receiving treatment to suppress the virus, there were no cases of transmission of the infection to the HIV-negative partner during sex without a condom. Although 15 men were infected with HIV during the eight-year study, DNA testing proved that was through sex with someone other than their partner who was not on treatment.

Given the chance, there are very few of us who wouldn’t want to slow down the aging process. Chasing that fountain of youth is a major branch of medical science at the moment, and a hardy little worm known as C. elegans is probably the most prolific test subject. Now, a team at Scripps Research has found that blocking a particular enzyme can extend the lifespan of these worms by almost half again.
