Cisco Cius Tablet: Another One Bites the Dust
The networking giant has put the kibosh on its Cius tablet. The business-oriented Android device, marketed to enterprise users, failed to take hold in face of the "bring your own device" movement.O.J. Winge, Cisco's senior vice president in its TelePresence Technology Group, penned a blog post late Thursday that explained the decision. In it, he discussed how we are facing a workplace that is no longer a physical place, but a blend of virtual and physical environments.
He described it as a place where employees are bringing their preferences to work and "bring your own device" is the new norm, where collaboration has to happen beyond a walled garden, and any-to-any connectivity is a requirement, not a "nice to have."
"As we announced last week, findings from the Cisco IBSG Horizons Study on virtualization and BYOD shows that 95 percent of organizations surveyed allow employee-owned devices in some way, shape or form in the office, and, 36 percent of surveyed enterprises provide full support for employee-owned devices," Winge wrote. "These stats underscore a major shift in the way people are working, in the office, at home and on-the-go, a shift that will continue to gain momentum."
Doubling Down on Software That shift is causing Cisco to emphasize software rather than hardware. Winge noted that over the past year Cisco had delivered software like Cisco Jabber and Cisco WebEx across a variety of operating systems, tablets and smartphones -- and he reported "tremendous interest" in those software offerings as the world moves toward a post-PC era.
"Based on these market transitions, Cisco will no longer invest in the Cisco Cius tablet form factor, and no further enhancements will be made to the current Cius endpoint beyond what's available today. However, as we evaluate the market further, we will continue to offer Cius in a limited fashion...

Plantwatch: The remarkable 'dent de lion' is becoming much more fierce
After nearly two months of torrential rains, the countryside is now as green as a billiard table, splashed with heaps of dazzling white hawthorn blossom. Trees are in full leaf and grasses are thick and lush, although their vigorous growth is shading out some of the smaller flowering plants, such as the early flowering orchids. But dandelion flowers have sprouted up in huge numbers, gorging themselves on the moisture as well as nutrients washed off farms and gardens. The name dandelion comes from the French "dent de lion", meaning lion's tooth from the toothed edges to their leaves. And in a warning sign of the changing atmosphere, the leaves may be getting toothier as carbon dioxide levels increase, as well as making the plants grow taller, lusher and stronger.
Flowers such as dandelions also have a canny habit of closing up in the wet weather to protect their pollen from the rain. But now the sun is shining, the flowers are open and making a more dramatic display.
Another remarkable spring flower is the mountain avens. This is an ancient relic of the cold climate at the end of the ice age and now grows on mountainsides in Scotland and Snowdonia. In the cold mountain air, the rose-like flowers track the path of the sun during the day like small solar energy collectors, trapping the sun's warmth to entice insects to visit and pollinate, and afterwards the heat is used for incubating the developing seeds.

The protein, Argonaute-2, is a key player in RNA interference, a powerful cellular phenomenon that has important roles in diverse biological processes, including an organism's development.

As the leader of the team invited to evaluate the public debate called GM Nation? in 2002-03 (Back to the battlefields, G2, 23 May), I would like to point out (yet again) that the initiative was not a survey, as conventionally understood, and was not based on anything like a representative sample of British citizens. Rather, participants in the debate activities were self-selecting. There is certainly significant opposition to GM in the UK, but the evidence suggests a greater number are more ambivalent. Indeed, evidence generated by GM Nation? suggests people's anxieties about the technology might not be so important if they could see clear advantages in terms of what GM products might offer them. For me, the real surprise is that advocates of GM have not been more bold in articulating the potential advantages (whatever they might be) of their products for consumers.
