Obama meets Lucy, 'the grandmother of humanity,' during Ethiopia visit

Guardian Science - Mon, 2015-07-27 23:25

Lucy is a 3.2 million-year-old member of Australopithecus afarensis and the most complete skeleton of an early human ancestor ever discovered

She had never heard of Barack Obama, or the United States for that matter, and did not say a word when she met the president before a state dinner in Ethiopia.

Lucy, a 3.2 million-year-old member of Australopithecus afarensis, is the most complete skeleton of an early human ancestor ever discovered. The fossil, normally housed in Ethiopia’s national museum, was brought to the national palace on Monday for Obama’s visit and helped put the ephemera of politics in perspective.

Climate change 'triple threat' increases severe flooding risk in biggest US cities

Guardian Science - Mon, 2015-07-27 18:22

Trio of sea-level rise, storm surge and heavy rainfall exposes coastal cities such as New York, Los Angeles and Boston to potentially catastrophic flooding in future

America’s biggest cities are at far greater risk of serious flooding in the coming decades than was previously thought, because of a “triple threat” produced under climate change, researchers said on Monday.

A combination of sea-level rise, storm surge and heavy rainfall – all functions of climate change – exposes New York, Los Angeles, Houston, San Francisco, San Diego and Boston to a much greater degree, research published on Monday in the journal Nature Climate Change found.

In defence of the Research Excellence Framework

Guardian Science - Mon, 2015-07-27 15:41

An as-yet-unannounced review of Business, Innovation and Skills-funded bodies raises a potential threat to the future of research funding. We need an intelligent, evidence-informed debate about the costs and benefits of assessment

In academic circles, it’s become fashionable to denounce the Research Excellence Framework (REF) as the sector’s very own spawn of satan. The REF, a six-yearly assessment of the qualities and impacts of UK research, is used to allocate around £1.6 billion of public funding on an annual basis. In these austere times, you might think that would be enough to win it a few friends. Instead, the critics are lining up.

The REF is “a bloated boondoggle”, a “Frankenstein monster” and “a Minotaur that must be appeased by bloody sacrifices”. It is responsible for a “blackmail culture”, a “fever” and a “toxic miasma” which hangs over our campuses, choking the dying gasps of creativity from academic life. Entire books have been devoted to its insidious “hypocrisies”. Sir Paul Nurse and Lord Stern, the presidents of our most eminent academies, query its “wasteful and distorting” influence. Even Jo Johnson, the science minister, is now trying to sell the virtues of teaching assessment on the basis that he has “no intention of replicating the individual and institutional burdens of the REF”.

Bryan Nelson obituary

Guardian Science - Mon, 2015-07-27 13:59
Ornithologist devoted to studying, filming and writing about seabirds, he became the ‘biographer’ of the gannet

Seabirds are to many ornithologists the most fascinating of all bird groups. For Bryan Nelson, who has died aged 83, they became a benign obsession, to which he devoted most of his professional and personal life as an author, zoologist and academic.

His passion for such birds found its outlet in several books, which ranged from a detailed and authoritative monograph on the gannet (The Gannet, 1978) to a concise introduction to the same species in the popular Shire Natural History series (1979). He once described himself as the “major biographer” of the gannet, but his masterwork, published in 2006, was a hefty volume entitled Pelicans, Cormorants, and their Relatives, produced by the Oxford University Press as part of its Bird Families of the World series. In addition to his books, Nelson also wrote numerous scientific papers and popular articles, appeared on radio and television, and made natural history films on seabirds.

Bone idol: museum's quagga skeleton restored with 3D-printed leg

Guardian Science - Mon, 2015-07-27 13:56

London’s Grant Museum of Zoology has completed work on its rare but neglected quagga skeleton – missing a leg and mistaken for a zebra for years

The tottering remains of one of the rarest zoological museum specimens in the world – a quagga whose ancestors were hunted to extinction in South Africa in the 19th century – is now standing firmly on four legs again through 3D printing, which recreated a flipped version of its right hind leg to replace the missing left leg.

Is my brain older than my body? – video

Fictional scientist Jeremy Bumble always thought he was wise beyond his Earth years – that somehow his brain was older than the rest of his body. Here he explains, with the help of Einstein's thinking on space time, and UCL professor of astronomy Ofer Lahav, that this is indeed the case. Go science!

Orangutan escapes from Perth zoo enclosure and mingles with visitors

Guardian Science - Mon, 2015-07-27 02:25

Zoo is conducting a review after Teliti, a five-year-old female, appears to have climbed a shade sail and jumped over enclosure outer wall onto boardwalk

Perth zoo is conducting a security review of its award-winning orangutan enclosure after one curious inhabitant managed to escape and mingled with human visitors in the public viewing area on Sunday.

Teliti, a five-year-old female orangutan who was born at the zoo, appears to have climbed up one of the exhibit’s shade sails about 11.30am before jumping to the outer wall of the enclosure and climbing onto the boardwalk.

Sleep sharpens power to recall memories, study finds

Sleep almost doubles chances of remembering previously forgotten information, according to new research

Last-minute “swotting” for an exam before going to bed might be a good tactic for students, according to research on the benefits of “sleeping on it”.

Sleep almost doubles the chances of remembering previously forgotten information, scientists found. They believe it makes memories more accessible and sharpens our powers of recall.

Some first results from the new, higher-energy Large Hadron Collider

Guardian Science - Sun, 2015-07-26 12:16

On 3 June this year, the Large Hadron Collider at CERN began delivering particle collisions at an energy 63% higher than previously achieved. This week in Vienna, first physics results were presented. Here are some highlights

The European Physical Society High Energy Physics conference is taking place now in Vienna. This is the first big chance for the experiments at the Large Hadron Collider (LHC) to show off what they have managed to extract from the new data they have recorded since 3 June, when the LHC restarted particle collisions after a two-year break.

The new collisions are at a higher energy - 13 TeV¹ compared to the previous record of 8 TeV. Since we are bumping up against the speed-of-light barrier, this means the speed of the protons increases from 299 792 449 metres per second to 299 792 454 m/s (the speed of light is 299 792 458 m/s). An increase of only 5 m/s, which doesn’t sound terribly important. But speed is the wrong way to judge the significance of the increase. The main point of high energies in particle colliders is that they allow us to see into the heart of atoms and study the structure of matter at tiny distance scales; in a way the LHC is like a giant microscope. Turning up the energy is like turning up the power of the microscope, and we are eager to see what that might reveal.

The scientific search for extraterrestrial civilisations has languished for more than a decade, as the hunt for habitable planets and simpler forms of life has thrived. Nasa’s stunningly successful Kepler mission has discovered a thousand new worlds orbiting other stars. Astrobiology is a burgeoning field. But the search for intelligent life, begun in 1960 by astronomer Frank Drake, somehow fell off the funding radar.
