Planck knocks 100m years off oldest stars, no Botox needed

Planck knocks 100m years off oldest stars, no Botox needed

Age may only be a number, but it turns out some of the oldest stars in the universe could be a lot younger than believed, according to new results from the Planck telescope. While scientists had previously estimated that the first stars began to shine 440m years after the Big Bang, itself pegged at 13.8 billion years ago, new results from the decommissioned ESA space telescope suggest that may have been off by as much as 100m years. Spilling the stars' age secrets are freshly calculated maps of cosmic background radiation, that help explain when reionization of the universe began.

New Horizons spacecraft wakes up to greet Pluto next year

New Horizons spacecraft wakes up to greet Pluto next year

It may be routine procedure, having been performed many times before, but it is symbolically one giant leap for mankind, particularly space exploration. Waking up to Russell Watson's "Where My Heart Will Take Me", long associated with space exploration and even Star Trek, NASA's New Horizons spacecraft became fully activated in preparation for its meetup with the smallest and farthest "former" member of our solar system, Pluto. It marks the near culmination of a journey that has so far lasted nearly nine years and three billion miles, the farthest any space mission has traveled to reach its target.

Dyson Humidifier employs UV light to keep air germ-free

Dyson Humidifier employs UV light to keep air germ-free

Dyson is really spreading its wings as far as its product lineup goes. Just last month it introduced to the world its first robot vacumm cleaner, the 360 Eye. Now, it is doing so again but with a humidifier. It doesn't have an ominous sounding name and is simply called the Dyson Humidifier. That doesn't mean, however, that it is any less interesting. This humidifier, which resembles and doubles as a bladeless fan, not only keeps your air cozily humid, it also kills germs before it distributes those water particles as well.

Samsung Galaxy Note 4 Review: Phablet Refocused

Samsung Galaxy Note 4 Review: Phablet Refocused

Samsung can’t afford to stumble with the Galaxy Note 4. The fourth-gen phablet arrives as Samsung wakes up to a new, and not especially rewarding, phase in its mobile life: the discovery that throwing a hundred designs at the market and hoping at least some of them stick no longer has the same sales success as it once did. At a time so fiercely competitive, Samsung can’t count on simply having originally created the Note 4’s segment to commend this latest model. It needs to deliver as much in the hand as its specifications promise to on the page.

Transparent solar panels could revolutionize cities & tablets

Transparent solar panels could revolutionize cities & tablets

Transparent solar cells that could one day mean your home, office, or even car windows are generating electricity have been developed, as well as opening the door to phones and tablets that create their own power. The research, led by a team at Michigan State University, has come up with a transparent luminescent solar concentrator which looks clear to the eye but can still harvest energy from wavelengths of light invisible to humans.

Painless “universal” cancer blood test being explored

Painless “universal” cancer blood test being explored

A universal blood test that could identify any type of cancer in a patient is one step closer, researchers say, potentially opening the door to diagnosing unusual variations and avoiding expensive and often painful invasive biopsies. Although in its early stages, the Lymphocyte Genome Sensitivity (LGS) test is already being explored for commercial purposes as Oncascan, spotting cancer by examining how readily white blood cells are damaged by ultraviolet light.
