Mars is emerging from an ice age that ended about 400,000 years ago

Mars is emerging from an ice age, according to a new study. Studying the Martian climate and how it changes over time can help scientists better plan future missions to Mars and even understand climate change here on Earth, the study authors say.

Models had already predicted that Mars underwent several rounds of ice ages in the past, but little physical measurements ever confirmed those predictions. Today’s study,

Battery life to get five times better

Scientists have discovered a new catalyst material which may lead to cellphone and car batteries that last five times longer than current ones. Kyeongjae Cho from University of Texas at Dallas (UT Dallas) in the US has found the catalyst materials for lithium-air batteries that jumpstart efforts at expanding battery capacity. “There is huge promise in lithium-air batteries. However, despite the aggressive research being done by groups all over the world, those promises are not being delivered in real life,” said Cho. “So this is very exciting progress. Hopefully, this discovery will revitalise research in this area and create momentum for further development,” he said.

Must Read, Ancient Egyptian spellbook revealed: Papyrus contains curses that claim to ‘burn the heart of a woman' and make men do exactly what you want

Recently translated texts dating back 1,700 years reveal the ancient spells that called upon both gods and demons in hopes to attain love, sex, and power. Researchers have uncovered numerous magical formulas which may once have been used in hopes to tamper with fate, requiring a person simply add the name of their target in order to lay a curse. The spells are just a small part of an expansive collection of Egyptian papyri discovered more than 100 years ago in the city Oxyrhynchus.

Dinosaurs may have had lips, research suggests. But could they whistle?

The "Jurassic Park" image of a Tyrannosaurus rex baring a mouthful of ferocious teeth may be getting a facelift. New research suggests that theropods -- those "beast-footed" terrestrial carnivores -- had lips and gums that covered most of their teeth, challenging toothy ideas of what they looked like. University of Toronto vertebrate paleontologist Robert Reisz presented the findings Friday at the Canadian Society of Vertebrate Paleontology's annual meeting in Mississauga, Ontario. "In popular culture, we imagine dinosaurs as more ferocious-looking, but that is not the case," Reisz said in a news

Get up close with Van Gogh: Google camera captures gigapixel images of art that lets users zoom in to see each brushstroke

Gigapixel image is made of 1 billion pixels and shows incredible detail

Google's Art Camera is being used in 25 new museums around the world

Google is today sharing the first 1,000 high resolution images of artworks     from artists including Pissarro, Signac, Rembrandt, Van Gogh and Mone 

Forget going to the Tate. Google has unveiled an incredibly high-resolution camera that will bring detailed works of art to your phone or computer.

Dubbed the 'Art Camera', the device has so far taken a thousand gigapixel images of famous masterpieces, which can all be viewed online by anyone for free.

A gigapixel image is made of over one billion pixels, and can bring out details invisible to the naked eye – allowing viewers to see individual brush strokes. 'Zooming into these images is the closest thing to walking up to the real thing with a magnifying glass,' writes Ben John and engineer at Google Cultural Institute. Google is today sharing the first thousand ultra-high resolution images of artworks from artists including Pissarro, Signac, Rembrandt, Van Gogh and Monet.

Around 200 of these gigapixel images were taken in the past five years, showing individual brush strokes and subtle changes in colour. But these first images were captured using highly specialised and expensive equipment, and required a trained technician to complete the job.

Genome Analysis Reveals How Giraffes Developed Exceptionally Long Necks

Why the long neck, you ask? Several genetic clues from the giraffe and its relative may provide insight on how the animals developed their exceptional height, a new study revealed. Considered as the world's tallest terrestrial species, giraffes are dominated by their long neck and legs, which contribute to their overall stature. These animals' size can reach up to 5.79 meters (19 feet) tall or nearly the equivalent of a two-storey building.

Additionally, giraffes can sprint at a speed of 37 miles per hour (60 km per hour). The animals' heart can pump blood two meters (6.56 feet) up to its brain, suggesting a powerful cardiovascular function. This is plausible, as its left ventricle has evolved to become unusually large.

Five Pacific islands lost to rising seas as climate change hits

Six more islands have large swaths of land, and villages, washed into sea as coastline of Solomon Islands eroded and overwhelmed. Five tiny Pacific islands have disappeared due to rising seas and erosion, a discovery though to be the first scientific confirmation of the impact of climate change on coastlines in the Pacific, according to Australian researchers.

The submerged islands were part of the Solomon Island

Don’t look but, for the first time in almost a decade, Mercury will pass across the front of the sun

The solar system’s smallest and most remarkable planet, Mercury, will cross the face of the sun on May 9 – offering a great opportunity for people in many places across the world to see it.

Mercury is a dark and enigmatic world, which bears the scars of a strangely long history of volcanic eruptions and tectonic activity. Its crust is unreasonably rich in elements that normally easily evaporate from the surface, such as sulphur, sodium and potassium. This is odd, as these are the kind of substances that are most likely to have been lost during a hot and violent birth such as Mercury’s.

Mercury scoots round the sun in only 88 days, overtaking the more sedately moving Earth every three or four months. Because Mercury’s orbit is tilted at about seven degrees with respect to the Earth’s, it passes directly between us and the sun (a transit) only when both it and the Earth are close to the points where their orbital planes intersect. This can happen only in early May or early November.

In every century there are only 13 or 14 transits of Mercury and you have to

Global, Local Leaders Vow Hard Work Against Temperature Rise

International leaders and local officials on Thursday pledged to work hard to stem the rise of global temperatures by investing in public transportation and electric cars, planting trees and switching to solar energy.At a climate action summit, U.N. Secretary-General Ban Ki-moon urged governments, businesses and civil society to make good on the landmark climate agreement concluded late last year in Paris by more than 170 countries. 

The deal aims to keep the global temperature rise below 2 degrees Celsius (3.6 degrees Fahrenheit) compared with preindustrial times. Ban called on cities to reduce greenhouse gas emissions and on companies to invest in green technologies with the goal or cooling the planet and ensuring cleaner air and better health. "We need action now," Ban said. "Temperatures continue to rise. Arctic sea ice is melting fast. Droughts, storms and floods are costing lives and productivity." 

World Bank President Jim Yong Kim said governments and corporations should

A New Climate Of Responsibility: New Developments Undermine Old Assumptions

The climate is changing. March marked the 11th straight month in which a global average temperature measure was set. But the climate of opinion is changing as well. Dramatic shifts are under way in how to grapple with the climate change threat.

In April, more evidence emerged about the oil industry’s early knowledge that global warming was real, before it switched into public denial mode.

We now know that warning signs were seen as early as the 1950s. Such evidence that has already lead to the opening of an FBI investigation, as well as state-level investigations announced by a coalition of 17 attorneys general in late March.

Also, in April, a federal judge allowed a landmark lawsuit to proceed against the federal government for discriminatory violations of the rights of youth and future generations by permitting and enabling fossil fuel use, leading to climate change.
