Ripe old age: humans may already have reached maximum lifespan

By Will Dunham WASHINGTON (Reuters) - When she turned 120 years old in 1995, plucky Frenchwoman Jeanne Calment was asked what type of future she expected. "A very short one," she replied. But Calment lived two more years, dying at age 122 with the longest documented lifespan of any person in history. Scientists who examined statistical trends regarding maximum lifespans said on Wednesday Calment's record may last a long time. An analysis of mortality and population data covering about 40 countries indicated humankind may already have hit its longevity ceiling, they said. ...

Blue Origin successfully tests capsule safety, lands booster

By Irene Klotz (Reuters) - A rocket owned by Jeff Bezos’ space company Blue Origin blasted off from Texas on Wednesday then unexpectedly landed itself intact after the crew capsule separated and parachuted to the desert floor in a successful test of safety systems. Blue Origin engineers had expected searing exhaust from the capsule’s motor would tip over the New Shepard rocket, causing it to shut down and then crash in a massive fireball in the desert.

Ginger and Acupressure for Morning Sickness? Science Says Maybe

For women with morning sickness, a range of remedies may be effective at alleviating mild to severe symptoms, but the evidence on how well they work is lacking, a new review from the United Kingdom finds. Up to 85 percent of women experience morning sickness during pregnancy, and the symptoms can affect their day-to-day lives, according to the review, published today (Oct. 4) in the journal JAMA. Of the 78 studies, 67 were randomized clinical trials, meaning that the people in the study were randomly assigned to receive either the treatment or a placebo.

Roman Bullets Tell Story of 1,800-Year-Old Attack on Scottish Fort

A bloody assault by Roman legions on a hill fort in Scotland around 1,800 years ago is being pieced together using the remains of Roman missile weapons that were used in the attack. The excavations at Burnswark Hill, in the Dumfries region of southwest Scotland, have unearthed the largest cache of Roman lead sling bullets yet discovered — part of the huge arsenal of missile ammunition used by the attacking legions to subdue the native defenders of the hilltop fort. So many sling bullets and other Roman missiles have now been found at Burnswark Hill that archaeologists think the raid was staged as a warning to anyone who resisted Roman rule: an act of "exemplary violence" designed to terrorize the Scottish tribes into submission, the researchers said.

Device Can Read Emotions By Bouncing Wireless Signals Off Your Body

Emotions can be tricky enough for humans to read, let alone machines, but a new system can predict people's feelings with 87 percent accuracy by bouncing wireless signals off them, researchers say. The setup, dubbed EQ-Radio, analyzes the signal reflected off a subject's body to monitor both breathing and heartbeat. Using a device smaller than a Wi-Fi router, researchers at MIT were able to monitor a person's breathing and heartbeat wirelessly.

Brainy bees learn how to pull strings to get what they want

By Kate Kelland LONDON (Reuters) - Scientists in Britain have managed to teach bumblebees to pull strings to get to food and then pass on what they have learned to others in their colony - showing a high level of intelligence despite their tiny brains. Researchers at Queen Mary University of London (QMUL) said the experiments, often used to test the intelligence of apes and birds, showed for the first time that some insects are up to the task, and can also pass skills on through several generations.
