BIG BEARS: Ancient bears evolved to become giants so they could scavenge prey killed by others, suggests a new study.

GREAT MOMENTS IN SCIENCE: People in the US used to be among the tallest in the world, but now that honour goes to the Dutch. Dr Karl gets to the bottom of the slide in height.

EVOLUTION OF CONSCIOUSNESS: Insects are conscious, egocentric beings, argue Australian scientists in a new paper that suggests basic consciousness may have first evolved in insects in the Cambrian Period.

SLEEP DEPRIVATION: Women's ability to perform tasks accurately is reduced when working night shifts into the early morning, according to a new study that details for the first time differences between men and women's sleep-wake cycles and circadian rhythms.

The city of Miami Beach is slowly disappearing under water. At the big high tides of the year the sea washes over the famous wide beach and floods many of the city streets and magnificent Art Deco buildings. And over the past decade the floods have been striking more frequently.

Most of the city sits just a few feet above sea level, built on a foundation of porous limestone, allowing the rising seas to seep into the city’s foundations, surge up through pipes and drains, encroaching on fresh water supplies and saturating infrastructure. The city is now investing in a $500m project to raise roads and a pumping system to hold back the floods.

Cambridge physicist and government scientific adviser with a rational approach to the climate and energy debate

Sir David MacKay, who has died of cancer aged 48, was a true polymath, a rare breed in today’s world, where the frontiers of scientific knowledge are increasingly remote and complex. It is a testament to David’s intellectual brilliance that he was able to contribute to advancing more than one of these frontiers during his short career.

David latterly achieved cult status among climate and energy aficionados following the publication of Sustainable Energy: Without the Hot Air (2008), initially self-published using £10,000 of David’s own money and offered – as were all his works – simultaneously free for download on his website. Described as a “tour de force” by the Economist magazine and lauded by Bill Gates as “one of the best books on energy that has been written”, within two years it had sold 40,000 copies and been downloaded nearly half a million times.

Government urged to crack down on rogue practice of garages removing compulsory diesel particulate filters from vehicles

More than a thousand diesel cars have been caught without an essential pollution filter that traps deadly particles, according to government figures. But experts warn the rogue practice of removing the filters, which contributes to air pollution-related deaths, could be far more widespread.

Almost 29,000 people die prematurely each year in the UK owing to particle pollution, causing £15bn in health costs. Since 2009 diesel particulate filters (DPFs) have been compulsory in new diesel cars. But, particularly for cars driven in cities, the DPFs can become clogged and cause breakdowns.

The Natural Environment Research Council have conducted a poll to help decide the name of its new £200m polar research vessel and the winning name is – RRS Boaty McBoatface – receiving 124,109 votes. Four times more than RRS Poppy-Mai, which came in second place. Despite the overwhelming result of the poll, the NERC are unlikely to use the winning name. The government says it wants a name that ‘reflects the serious nature of the science it will be doing’

NERC chief has final say and faces dilemma between credibility of the organisation and burden of public opinion

Latest: Boaty McBoatface may not be name of new polar research vessel

Forget the EU referendum. The major test of modern democracy has fallen into the hands of the Natural Environment Research Council – over the naming of a boat.

As the polls finally closed for the naming of its new polar research ship, the NERC confirmed that the votes were overwhelmingly in favour of RRS Boaty McBoatface.

Conservationists are putting fragments of information together to learn more about this enigmatic winged creature that only three living people have seen

Somewhere here among the red-dirt channel country of south-west Queensland is a bird that was, until recently, literally a legend.

After a day in which Britain generated more power from the sun than from coal for the first time, the industry should be rejoicing. But the mood is fearful

Given that the government is determined to avoid playing a financial role in the planned new nuclear plant at Hinkley Point, it is perhaps surprising that it is involved in the UK’s largest solar array.

The 70-megawatt Lyneham photovoltaic farm – big enough to provide light and heat to 20,000 homes – is located at a former RAF base in Wiltshire owned and rented out by the Ministry of Defence.

Average global temperature was 1.07C hotter - beating last month’s previous record increase

The global temperature in March has shattered a century-long record and by the greatest margin yet seen for any month.

February was far above the long-term average globally, driven largely by climate change, and was described by scientists as a “shocker” and signalling “a kind of climate emergency”. But data released by the Japan Meteorological Agency (JMA) shows that March was even hotter.

SUPER SWEEPER: At least one super-Earth could have formed close to the Sun sweeping away debris before the planet was destroyed, a new study suggests.

CORAL BLEACHING: Sea temperature rises of as little as 0.5% could see more than a quarter of corals on the Great Barrier Reef lose their ability to survive bleaching events.

Australia's State Party Report on the state of conservation of the Tasmanian Wilderness World Heritage Area, 2016

Coastal Risk Australia combines Google Maps with detailed tide and elevation data, as well as future sea level rise projections

For the first time, Australians can see on a map how rising sea levels will affect their house just by typing their address into a website. And they’ll soon be able to get an estimate of how much climate change will affect their property prices and insurance premiums, too.

Launched on Friday, the website Coastal Risk Australia takes Google Maps and combines it with detailed tide and elevation data, as well as future sea level rise projections, allowing users to see whether their house or suburb will be inundated.

Wildlife experts say the bird likely died of natural causes after they fail to spot him at his usual haunts in the Lake District

England’s only resident golden eagle is likely to have died after failing to appear this spring, wildlife experts fear.

The bird, which has been a resident at Riggindale near Haweswater, Cumbria, since 2001, has not seen by RSPB staff since last November, and would normally be seen at this time of year building a nest and displaying to attract a mate.

INSECT INNOVATION: Life in the scorching hot Sahara Desert is no problem for an ant that has evolved an effective and stylish heat-repellent system, new research finds.

AGED CARE: Video chatting with relatives over the internet might be able to reduce the risk of nursing home residents with dementia from becoming agitated or even aggressive, new research suggests.

All-star team with authors of seven previous climate consensus studies collaborate to debunk the ‘no consensus’ myth once and for all

There is an overwhelming expert scientific consensus on human-caused global warming.

Authors of seven previous climate consensus studies — including Naomi Oreskes, Peter Doran, William Anderegg, Bart Verheggen, Ed Maibach, J. Stuart Carlton, John Cook, myself, and six of our colleagues — have co-authored a new paper that should settle this question once and for all. The two key conclusions from the paper are:
