| The big male nose: Why men's noses are bigger than women's Posted: 18 Nov 2013 01:00 PM PST Why are men's noses bigger than women's? The answer, according to a new study lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which requires more oxygen for muscle tissue growth and maintenance. It also explains why we have smaller noses than our ancestors. |
| Bacteria recycle broken DNA: Modern bacteria can add DNA from creatures long-dead to its own Posted: 18 Nov 2013 12:58 PM PST From a bacteria's perspective the environment is one big DNA waste yard. Researchers have now shown that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with resistance to antibiotics in hospitals and in our perception of the evolution of life itself. |
| Promiscuous mouse moms bear sexier sons Posted: 18 Nov 2013 12:29 PM PST Biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young. They attract more females by making more urinary pheromones, but smelling sexier shortens their lives. |
| DIY and save: A scientist's guide to making your own lab equipment Posted: 18 Nov 2013 07:22 AM PST Joshua Pearce has penned a how-to book on the open-source 3-D printing technology that could revolutionize how science is done all over the world. |
| World's smallest FM radio transmitter Posted: 18 Nov 2013 06:15 AM PST Scientists have taken advantage of graphene's special properties —- its mechanical strength and electrical conduction —- and created a nano-mechanical system that can create FM signals, in effect the world's smallest FM radio transmitter. |
| More than 600 ancient seals and amulets found in Turkey Posted: 18 Nov 2013 05:10 AM PST Archaeologists have made an unusually large find in Turkey which has provided surprisingly vivid insights into the piety of the time. They discovered more than 600 stamp seals and cylinder seals at the sacred site of the storm and weather god Jupiter Dolichenus. |
| Research program to tackle asteroid, space debris manipulation Posted: 18 Nov 2013 05:09 AM PST World-leading scientists will push the boundaries of studies on how to deflect asteroids and manipulate space debris. |
