The technological trends change very fast. If you are not able to change with technology then new technology makes you outdated. So, we have to keep an eye on the past and future trends of technology. Initially an idea makes a concept which in turn takes shape and then we see the products based on that concept in the coming days, months or year. Enlisted below are such concept laptops which may b
Just because you're online doesn't mean that you can't experience the world first-hand -- or as close to first-hand as possible. Here are websites that feature virtual learning experiences, exposing online visitors to everything from history to geography, astronomy to anatomy, literature to government.
A space-based survey of 101 objects that pass relatively close to Earth has found they have a wide range of reflectivity, indicating that their composition is varied as well. [More] Asteroid - Solar System - Earth - Astronomy - Small Bodies
Helicopter-mounted lasers that can dazzle and defend against heat-seeking missiles are now under development, researchers reveal. [More] Laser - Missile - Infrared homing - Helicopter - Business
The middle-aged Internet ( ARPANET first went live more than 40 years ago ) could easily slide into complacency, but the National Science Foundation (NSF) might be staving this off with four multimillion-dollar grants that the agency has recently awarded. The Future Internet Architecture (FIA) research projects are expected to re-think the network from the ground up, taking into account emergi
With this final column I will transition Sustainable Developments from Scientific American to the home page of the Earth Institute ( www.earth.columbia.edu ). Although I will continue to contribute occasional essays to the magazine, I will use this last regular column to say thank you and take stock of the deepening crisis of sustainable development.During the four years of this column, the wor
Nature certainly has a way of one-upping the fruits of human ingenuity. Extreme astrophysical objects have long been known to accelerate the particles that make up cosmic rays to whopping energies that make the Large Hadron Collider look like a child's slingshot. The mammoth collider near Geneva, Switzerland, which resumed service in 2009 after an aborted start-up the year before, will ultimate
Treatment of severe depression with magnetic stimulation is moving beyond large mental health centers and into private practices nationwide, following more than two decades of research on the treatment. Yet even as concern about its efficacy fades, one potential side effect--seizures--continues to shadow the technology. [More] Mental health - Health - Major depressive disorder - D
Editor's note: We celebrate Scientific American's 165th anniversary on August 28 with this reproduction of what amounts to the cover story . Interestingly, the story states that passengers would comfortably be "flying" at 30 to 40 miles per hour; contrast that with the last line of the "Morse's Telegraph" story in the same issue, which described railroad cars as "slow

Wireless gadgets have changed the way nearly everyone communicates, but one group has benefited more than others: the deaf. For those who cannot make a voice call, texting and video, in particular, have not only opened them up to the hearing world and to each other, but also allowed them to use American Sign Language (ASL) , often their native language. [More] American Sign Languag
A new analysis of a meteorite shows that an inclusion within the carbonaceous stone is older than any known material in the solar system. The finding pushes back the estimated age of the solar system to 4.568 billion years, older than previous estimates by up to 1.9 million years.

With all due respect to T. S. Eliot, maybe the world really does end with a bang, not a whimper. Whether of our own creation (nuclear holocaust) or of nature’s (asteroid impact), plenty of cataclysms could doom civilization--perhaps even putting the survival of the species in jeopardy. We assessed the likelihood of several doomsday scenarios, from oft-discussed threats such as climate chang
The best places to collect solar energy are also some of the dustiest on Earth and beyond, a quandary that leads to inefficiencies in how well the cells are able to convert strong sunlight into renewable electricity. The solution, according to new research, is to coat solar cells with material that enables them to chase away dirt particles on their own with the help of dust-repelling electrical
Stem cells have been touted as potential antidotes to nearly everything ranging from blindness to paralysis, as well as valuable models on which to study disease. But in order for researchers to discover and refine new cell-based treatments, they need plenty of cellular subjects. [More] Stem cell - Research - Biotechnology - Cell - Biology
There is no such thing as the Nobel Prize in Mathematics, but fortunately the field of math dishes out its own top honors every four years, bestowing the prestigious Fields Medal on two to four researchers. (Unfortunately for mathematicians, the cash prize attached to the Nobels is a far sight bigger.) [More] Fields Medal - Mathematics - Math - Nobel Prize - Mathematicians
