Early Man was not alone: study

PARIS — Modern man’s forerunners shared the planet with at least two related species nearly two million years ago, scientists said on Wednesday, pointing to newly-unearthed pieces in a 40-year-old fossil puzzle. Findings published in the journal Nature touch on the odyssey of our ancestor, the upright-walking early human known…

Cognitive researchers find truth in Colbert’s ‘truthiness’

Scientists in New Zealand and Canada have found Stephen Colbert’s concept of “truthiness” isn’t just a late-night ruse to get laughs; the concept can also help explain how the human brain evaluates claims. “We wanted to examine how the kinds of photos people see every day — the ones that…

NASA shows first ‘crime scene’ photo of Mars landing

WASHINGTON — About 36 hours after the US space agency’s landed its $2.5 billion rover on Mars, NASA released Tuesday what it called a “crime scene” aerial shot of where the parachute, heat shield and rover came down. The touchdown on August 6 of the Mars Science Laboratory involved the…

Physicists on ‘Armageddon’: A nuke would have been a ‘cheap firecracker’ on an asteroid

When Bruce Willis used a nuclear bomb to save Earth from a giant asteroid in the movie Armageddon, the scenario had little science and a lot of fiction, physicists said on Tuesday. Willis’ nuke would have had as much impact on the rock as a cheap firecracker and was used so late that the…

Study: Chance that extreme weather isn’t cause by climate change is ‘negligible’

Unusually hot summers, and the destructive droughts and wildfires that follow, are the product of climate change, according to a study of recorded global temperature data by a prominent Nasa scientist. The study uses recorded temperature data, rather than prediction models, to assert that climate change is responsible for recent extreme weather events including last…

Pfizer, Johnson drop tests for new Alzheimer drug

NEW YORK — Pfizer and Johnson & Johnson said Monday they had given up tests of a new therapy to treat Alzheimer’s disease, saying the treatment did not measure up to expectations. The final, phase 3 trial of the intravenous bapineuzumab therapy did not meet targets for effectiveness in aiding…

Waitresses who wear red earn bigger tips from men, study finds

Research recently published in the Journal of Hospitality and Tourism Research has found that waitresses who wear red earned bigger tips from men than waitresses who wore other colors. “As red color has no negative effect on women customers, it could be in their interest to wear red clothes at…

Mohawked flight director becomes surprise hit of Mars Curiosity landing

Usain Bolt may have rocketed to victory in the Men’s 100 final on Sunday, but thousands of miles away, another man was rising to prominence with great speed. The Mars Curiosity Landing, which made a safe touch down on the red planet at 06.14 BST today, wasn’t just a further…

Study: Chemotherapy can backfire and boost cancer growth

Cancer-busting chemotherapy can cause damage to healthy cells, which triggers them to secrete a protein that sustains tumor growth and resistance to further treatment, a study said Sunday. Researchers in the United States made the “completely unexpected” finding while seeking to explain why cancer cells are so resilient inside the…

Scientists unravel ‘other’ malaria parasite’s DNA code

Scientists said Sunday they had unraveled the genetic codes of parasites responsible for the bulk of malaria cases outside Africa, and found they were scarily diversified and may be harder to kill. In a study published in Nature Genetics, researchers said they had sequenced the genomes of four strains of…
