NASA is reporting that their Mars Reconnaissance Orbiter has discovered a vast field of a "long sought-after mineral" on Mars, called carbonate. Using the craft's Compact Reconnaissance Imaging Spectrometer (CRISM), the finding indicates Mars had neutral to alkaline water as far back as 3.6 billion years ago. This indicates the Martian planet has remained watery, increasing greatly the possibility that it has supported life.
Previous estimates are way off in regards to the world’s coal reserve, says a new calculation from Caltech. If this is true, this information could have a huge impact Earth’s future climate forecasts and the impact of man on the greenhouse effect.
MIT researchers working in conjunction with teams from the Technical University of Lisbon have created a computer model which will allow them to significantly advance the ability to capture more energy from ocean waves striking the shore. They have already designed ways to compress huge volumes of air, resulting in continuous power generation despite infrequent or variable sized waves.
On February 17, 2009, all analog broadcast TV stations transmitting their signals through their air are required to switch to digital transmissions by new FCC regulations. But are American consumers prepared for the switch?
Forterra Systems will soon issue a new report claiming that enterprise virtual worlds are much more effective than web conferencing for conducting business. Forterra’s goals run parallel to the report as their desire is to deliver that kind of virtual world technology and software to the real business world. ReadWriteWeb.com had an exclusive opportunity to view the report. Let's see what they found out.
Dell announced plans to reduce desktop and laptop packaging materials by approximately 10% worldwide, increase sustainable content in cushioning and corrugate packaging by 40% and 75% of packaging components are curbside recyclable by 2012.
Yesterday, Toshiba, IBM and AMD announced that via a joint effort they have developed a SRAM cell just 0.128 μm2. The cell is more than 50% smaller than the previous record holder, a nonplanar-FET cell measuring 0.274 μm2. SRAM is used in a computer's cache. Smaller SRAM cells means less heat, greater performance and lower production costs as it requires less silicon real-estate to produce similar cache sizes.
NASA reported its latest findings on dark energy today. They have now "clearly seen" the effects of dark energy in our universe.
The Huygens craft has made some amazing leaps for our science. For example, it landed a probe on one of Saturn’s moons in 2005. Now, the craft has managed to send back the first pictures of extraterrestrial liquid ever taken.
A lousy economy might endanger Macworld Expo, the biggest Apple-oriented consumer exhibition in the world. The spectacle that always draws incredible media attention is Steve Jobs' legendary keynote address when the Apple CEO usually unveils refreshed products, announces new initiatives and stuns the crowd with "one more thing." However, a depressed economy has prompted a number of key exhibitors to either downsize or skip the upcoming event completely. And now we are receiving information that Jobs' keynote also hangs in the air.
A new form of non-alkali membrane used in fuel cells could allow expensive and rare platinum to be replaced with nickel. If true, the market could soon be filled with much less expensive fuel cells and a changing attitude toward fuel economy in automobiles as fuel cells can be more efficient than internal combustion engines.
Intel published the findings of a recent survey conducted on 2,119 Americans aged 18 and over. When asked question regarding the significance of daily Internet access in their lives, 65% of respondents said they could not live without daily access. 71% said it was important or very important to have Internet-enabled devices (95% said it was "somewhat important"). And the big one: A stunning 46% of women and 30% of men aged 18-34 said they would rather go without sex for two weeks rather than lose daily Internet access for the same period of time. Those numbers also increase slightly with age.
"What a surprise!" said California Institute of Technology's (CIT) Richard Mewaldt when in 2006 NASA's twin STEREO spacecraft detected a 90-minute long stream of hydrogen atoms flowing out of the sun following the eruption of an X9-class solar flare (one of the largest in the past 30 years). Astronomers now believe they have figured out how the sun was able to emit huge quantities of hydrogen following the flare, when traditional wisdom held that everything should have been destroyed into sub-atomic particles.
A tiny seawater laboratory smaller than a stick of gum is showing how amazingly complex and mobile the underwater world of microscopic sea-life can be. In fact, it's helping MIT rewrite the book on understanding changes in global climate as these carbon munching microbes affect the macro world by transferring energy rapidly through the food chain.
Google’s strategy to update its browser more frequently has positively
impacted Chrome’s market share and the release of the final version of
the browser helped the software to jump back over the 1% mark again.
After two years of scientific research conducted from a stable Mars
orbit some 186 miles above the planet's surface, over 9 TB of data have
been beamed back by the Mars Orbiter. Having now successfully completed
its primary mission, the spacecraft has already found strong evidence
of a complex Martian history with a watery past and indications of
climate change over hundreds of millions of years.
Expanding its business beyond its core strength, microprocessors, has
always been difficult for Intel. Trends have been followed and
abandoned again in the past and now it is time to consider a new
business field for the company, co-founder, former chairman and CEO
Andy Grove says: Car batteries.
An Archimedes creation over 2000 years old was found around 1900. It is
now been studied and reconstructed. The researchers have found it to be
a fully functioning computer, showing the relative position of heavenly
bodies in continuous cycles. The inner workings are gear-based and move
via a knob that provides the energy of motion. Archimedes could have
used the device to track the position of the moon and five known
planets in the past, present or future.
MIT physicist Jocelyn Monroe is fascinated with dark matter. The only problem is, she's having a hard time finding any. Leading theories state that a functioning dark matter detector would detect non-dark matter collisions 10 billion billion times more often than it would detect a single dark matter collision. So, to address this rarified reality, she's been designing a much better dark matter detector.
An Israeli company called Innowattech has developed a way to recoup energy from cars operating on public roadways. Using piezoelectric crystals installed under the asphalt, highway vibrations are converted into a staggering amount of electricity. According to the developer, up to 500 kilowatts from a busy four-lane road per kilometer: Enough to power about 100 homes.
