Genetic discovery points the way to much bigger yields in tomato, other flowering food plants

[quote=", post:, topic:"]
Every gardener knows the look of a ripe tomato. That bright red color, that warm earthy smell, and the sweet juicy flavor are hard to resist. But commercial tomato plants have a very different look from the backyard garden variety, which can grow endlessly under the right conditions to become tall and lanky. Tomatoes that will be canned for sauces and juice are harvested from plants that stop growing earlier than classic tomato varieties, and are therefore more like bushes. While the architecture of these compact bushy plants allows mechanical harvesters to reap the crop, the early end of growth means that each plant produces fewer fruits than their home garden cousins.

^ in reality, a simple adopter at 5V and required amps can be made in as little as 75rs... i recently bought a 5V 2A adopter for my usb hub at 100rs.. converted its pin for 25rs more.. that was it.. and it has been working fine.


12V adopters are at the same price range also.

ok

does anybody else feel 1x1?

Nah ... its you just being a sissy that's all :P:D

^ :(

^

Han kya? :lol:

I mean why 1x1 would even be your problem? Its a nice science/tech related thread & probably the only one which fits the scope of this forum and you're getting worried about 1x1? :wacko:

what the heck is this 1x1 you talking about :angry:

Binary brown dwarf system may contain closest exoplanet to Sun

[quote=", post:, topic:"]
It has only been within the last 20 years that we’ve discovered planets outside of our solar system, although astronomers have always believed they exist. Now, though, new exoplanets are discovered every day, including some that may even be habitable. Thanks to NASA’s Kepler mission, we have detected more than 3,500 potential exoplanet candidates. In fresh news: a team of astronomers at the European Southern Observatory may have discovered the most exciting — and closest — exoplanet yet.

This new potential exoplanet exists within a system of two brown dwarf stars, named Luhman 16AB. This system, which is only 6.6 light years away from Earth, was first discovered last year when astronomers looked over data from NASA’s Wide-field Infrared Survey Explorer (WISE) spacecraft. Luhman 16AB is so close, in fact, that television transmissions of Dexter are now getting there (Dexter premiered in 2006). By studying orbital cycles, astronomers determined that the mass of these brown dwarfs is about 40 times that of Jupiter.

New MRAM technology promises memorable consumer electronics experience

[quote=", post:, topic:"]
In his 2005 paper, Professor of Physics Johan Åkerman touted magnetoresistive random access memory (MRAM) as a promising candidate for a "universal memory" that could replace the various types of memory commonly found alongside each other in modern electronic devices. A team of researchers from the National University of Singapore (NUS) and Saudi Arabia's King Abdullah University of Science and Technology (KAUST) has now developed a new type of MRAM that could see Åkerman's vision become a reality.

Currently, many devices pack static random access memory (SRAM), dynamic random access memory (DRAM), and Flash memory, with each offering their own particular advantages. SRAM is fast but volatile, meaning the data it stores is lost when the power is switched off. DRAM offers greater memory densities than SRAM and is cheaper, but is also volatile and needs to be refreshed periodically to retain information, making it more power hungry. Finally, Flash memory is non-volatile, meaning it retains data even when the power is switched off, but is still relatively expensive.

MRAM technology offers the potential of providing all the advantages of these three types of memory, with none of the disadvantages. It promises greater storage density, reduced power consumption, and would retain data without power. Although it has been under development since the 1990s, continuing improvements in Flash and DRAM have kept MRAM largely on the sidelines.

The Rise of the Levitating Mouse

[quote=", post:, topic:"]

Russian designer Vadim Kibardin has designed a levitating mouse for the computer. This may either sound like magic or science fiction, but Kibardin’s design is based on principals of basic ergonomics.

The repetitious movements of mouse work at the computer, if you’re a graphic designer or gamer, eventually lead to impaired movement and flexibility of your hand and wrist. If left untreated, the median nerve that manipulates most of your hand can pinch and become trapped, limiting mobility altogether.

Kibardin observed that Carpal tunnel syndrome, the effect of consistent stress on the median nerve, is a modern problem, especially for people who use computers for most of the day. His levitating mouse uses a system of magnets to float the object in a fluid space that doesn’t create as much resistance.

The levitating mouse frees the wrist from a stationary position to a flexible position, releasing the median nerve from extra tension.

FUTURE IMPLICATIONS

Magnetic technology has improved movement in a variety of contexts. Maglev trains move close to 400 miles per hour now. Computer hard drives have used magnets since their inception. Instead of designing tools that require stationary movement, the use of magnets can manufacture tools that work more fluidly with a mutual resistance that feels more flexible. It will be very exciting to see technology like the kind Kibardin used in more fields.

The amazing alien planet discoveries of 2013

[quote=", post:, topic:"]

The range of alien planets found in 2013 ranged from planets that would be perfect for Earthlings...if only they weren't so hot or were 'water worlds.'

While astronomers didn't bag that elusive first "alien Earth" in 2013, they made plenty of exciting exoplanet discoveries during the past year.

Here's a list of the top exoplanet finds of 2013, from a tiny world about the size of Earth's moon to a blue gas giant on which it rains molten glass:

The smallest exoplanet

In February, astronomers announced the discovery of Kepler-37b, the smallest alien world ever found around a sun-like star. The planet is about 2,400 miles (3,900 kilometers) wide, making it just slightly larger than Earth's moon. [9 Exoplanets That Could Host Alien Life]

Kepler-37b, which was spotted by NASA's prolific Kepler space telescope, lies about 215 light-years from Earth. The exoplanet is likely far too hot to host life as we know it; it zips around its parent star once every 13 days.

The most Earthlike world yet

Also this year, researchers found the closest thing to an Earth twin in size and composition, though it's far too hot to support life as we know it.

Kepler-78b is just 20 percent wider and about 80 percent more massive than our planet, with a density nearly identical to that of Earth. The alien world, which is about 400 light-years from Earth, lies just 900,000 miles (1.5 million km) from its host star and completes one orbit every 8.5 hours. Surface temperatures on Kepler-78b likely top 3,680 degrees Fahrenheit (2,000 degrees Celsius), researchers say.

1,000 alien planets

Astronomers found the first-ever planets orbiting a star other than our sun in 1992. And in 2013, barely two decades later, they notched alien world number 1,000 — at least according to some tallies.

Two of the five main databases that catalog alien-planet discoveries passed the 1,000 mark this year, with both the Extrasolar Planets Encyclopedia and the Exoplanets Catalog, run by theUniversity of Puerto Rico at Arecibo's Planetary Habitability Laboratory, recording 1,056 alien worlds as of today (Dec. 26).

The other three databases — the NASA Exoplanet Archive, the Exoplanet Orbit Database, and the Open Exoplanet Catalog — have the tally at 976, 756 and 973, respectively. (The different numbers reflect the uncertainties inherent in exoplanet detection and confirmation.)

The first exoplanet cloud map

Also this year, astronomers created the first-ever cloud map on a planet beyond our solar system.

After observing the planet — a gas giant named Kepler-7b — for more than three years with NASA's Hubble and Spitzer space telescopes, scientists detected a reflective signature that they interpreted as clouds. [Gallery: A World of Kepler Planets]

The west side of Kepler-7b's atmosphere harbors many clouds while the east side has clear skies, researchers say. The planet, which was discovered in 2010, is about 1.5 times the size of Jupiter but less than half as massive.

Two potentially habitable 'water worlds'

In April, scientists announced the discovery of Kepler-62e and Kepler-62f, two explanets in the same solar system that both may be capable of supporting life as we know it.

The alien worlds are slightly larger than Earth, and modeling studies suggest that each is probably covered by an uninterrupted global ocean. Kepler-62e and f "look very good as possibilities for looking for life," Kepler mission principal investigator Bill Borucki, of NASA's Ames Research Center in Moffett Field, Calif., said back in April.

The hottest gadgets of CES: 3-D printers to 4K TVs

The biggest gadget trade show in the Americas wrapped up on Friday in Las Vegas after swamping the city with 150,000 attendees. This year, "wearable" computing was big, along with various 3-D technologies, especially 3-D printing.

[quote=", post:, topic:"]

Wearable devices in the shape of smartwatches and head-mounted displays have been a staple of the show for a long time, but manufacturers were excited this year because the field is finally gaining traction with consumers. Fitness bands were a breakout hit last year. The 3-D printing section bustled with activity, and it was clear that even though most people won't be buying a printer any time soon, they may be enjoying 3-D printed products, such as jewelry, wedding cakes and dental braces, in the near future. Meanwhile, TV makers were heartened by the support they received for their new ultra-high-definition TV sets.

Here are some of the most notable products and services revealed at the show:

DRIVERLESS CARS—The state of the art in car electronics is in systems that eliminate or ease the task of driving. French company Induct demonstrated its Navia driverless shuttle, which putts along at 12.5 miles (20 kilometers) per hour on a pre-programmed route. It's intended for university campuses, airports and other locales with enclosed roads.

With 3D Chips, Samsung Leaves Moore's Law Behind

With 3D Chips, Samsung Leaves Moore's Law Behind - Forbes

[quote=", post:, topic:"]

Samsung Electronics earlier this month began to commercially produce three-dimensional V-NAND flash memory chips capable of holding 128 gigabits of memory. And today the company showed off the first solid-state drives made with the chips see photo) at the Flash Memory Summit taking place in Santa Clara this week.

^ this could mean good things to come indeed..!!

moore's law says it doubles, now in the case of 3d chips it would be 4x or either a possibility of 6x.
but either ways it would be great to have such innovation, and buy high end machines at much cheaper prices. :D
And eventually there will be more "good things" as farhan said in near future.
