Labour MPs fear No 10 team lack up-to-date energy insight and don’t fully recognise voters’ climate concerns

Andy Burnham was told he could face the first revolt of his premiership as Labour MPs and climate experts condemned his apparent support for renewed drilling for oil and gas.

As the UK suffers through drought, fires and heatwaves, the prime minister gave the strongest indication yet on Friday he was minded to allow new drilling. His comments came just hours before the UN secretary-general warned “every new fossil fuel project” made heatwaves more dangerous.

Emergency crews say situation remains ‘dynamic’ as more than 100 firefighters battle Dunwich Heath blaze

A wildfire near Britain’s biggest nuclear power station has caused “total devastation” to one of the UK’s most important landscapes, as fire crews said the situation remained “dynamic”.

More than 100 firefighters have been battling the blaze on Dunwich Heath, near Leiston, on the Suffolk coast since Wednesday evening. The fire service said on Friday afternoon the situation was stabilising but remained a “major incident” that was “dynamic and potentially changeable”.

We would like to hear from people who have recently installed renewable energy sources in their home, or considered doing so

Great Britain has recorded more new solar power installations in the first half of this year than in any six-month period since 2011, with most of the new panels going onto household rooftops rather than large-scale solar farms.

The government’s data also shows a rise in households turning to other low-carbon technology: applications to the boiler upgrade scheme, which offers grants for replacing gas boilers with greener alternatives, reached 4,512 last month – up 21% on June last year – with demand for heat pumps expected to climb further in the months ahead.

It marked the city's first smog incident. Here’s what it looked like—back then and over the years that followed.

Boom in solar farms and home installations in first half of 2026 began shortly after start of US-Israel war against Iran

Great Britain has recorded more new solar power installations in the first half of this year than in any six-month period since 2011, as households turn to rooftop panels to help cut their energy bills.

An analysis of the government’s official figures shows that Great Britain added 142,536 solar installations in the first six months of the year, putting it on track to top last year’s record solar additions.

PM tells reporters the government cannot ignore the energy resource ‘when people are struggling’

Andy Burnham has said he will take a “pragmatic” approach to oil and gas drilling in the North Sea, saying the government could not ignore the potential energy resources it holds.

The prime minister’s comments came in response to a question about his conversation with Donald Trump on his first day in No 10. Trump had said Burnham told him he would “open up” North Sea oil, something the UK summary of the call made no mention of.

The spots on a leopard, the stripes on a zebra, and the mask on a raccoon are all types of coloration in mammal fur, referred to as pelage. Scientists have struggled for a long time to understand how these colorations evolved. A team of researchers recently discovered how to reconstruct the colors of ancient mammal fur using cell structures that contain the chemical pigment melanin, known as melanosomes. They hope to use this understanding of ancient mammal pelage to determine how they lived and what their environments were like.

To decipher the color of ancient mammal fur, the researchers constructed a statistical computer model to predict their fur colors based on the shape of their melanosomes. First, they needed to understand how the shapes of melanosomes control fur color in modern mammals. To measure the length and width of the modern melanosomes, the scientists used a beam of electrons like a flashlight to map them in great detail, a technique called scanning electron microscopy.

They measured the length and width of 2,615 melanosomes from the fur of 116 different living mammal species, including a Red Panda, a German Shepard, and one or more species of most types in the mammalian classification. Then they recorded the wavelengths of light reflected off each melanosome using a microspectrophotometer. These wavelengths represented the exact color of hair from each melanosome they measured. This means they now had a quantitative measurement of the color of each hair to compare with its corresponding melanosome length and width.

When they examined their data, the researchers found that spherical melanosomes produced brighter fur colors, like reds and oranges, while elongated melanosomes produced darker fur colors, like browns and grays. The researchers plotted the microspectrophotometric measurements for each melanosome as a graph showing how much light it absorbed across each possible wavelength, creating reflectance curves. Based on these data, the researchers used computer software to create a statistical model that could predict reflectance curves, and therefore color, from melanosome shape alone.

Once the researchers created a model, they needed to find fossilized mammal melanosomes to predict their fur color. Mammal fossils are rare, and pieces of cells are only preserved in the most immaculate fossil deposits. In fact, these researchers only found 6 fossils of this caliber, from Mesozoic rocks deposited around 250 million years ago, soon after mammals evolved. 

The fossils came from 2 world-renowned deposits in Northeastern China, the Yanliao and Jehol biotas. They selected 5 previously studied fossils from these locations, including 1 specimen of Megaconus mammaliaformis, 1 specimen of Vilevolodon diplomylos, 2 specimens from the group Docodonta, and 1 specimen from the group Eutheria. All of these animals were small, rodent-like mammals. The researchers also discovered a new species of tree-dwelling mammal, Arboroharamiya fuscus.

The scientists used scanning electron microscopy to measure a total of 2,159 fossilized melanosomes to refine their color predictions. The fossilized melanosomes were all slightly elongated spheres and had far fewer differences in shape than in modern mammals. The researchers used their model to predict reflectance curves based on the shapes of the fossil melanosomes to determine the ancient mammals’ colors. They found that all the extinct mammals they examined likely had dark brown fur without any color patterns.

Based on these findings, the researchers suggested that most, if not all, early mammals were nocturnal, like many dark-colored mammals today. They suggested that this nocturnal lifestyle probably helped them survive the meteorite impact that wiped out the dinosaurs 100 million years later. While dinosaurs were unable to survive in the post-impact wasteland, these smaller, dark-colored mammals were more resilient and thrived in the aftermath. As mammals filled the ecological roles left by the dinosaurs, they evolved new color patterns, some based solely on camouflage, and others on new factors, like sexual selection and visual communication.

The researchers concluded that their model can predict fossilized mammal colors and help determine how these ancient animals lived. Notably, their data suggest that mammals likely stayed small and nocturnal throughout the Mesozoic until the dinosaurs were gone. Future researchers could use similar methods to uncover exactly how mammals evolved the colors we see today. For example, studying mammals closer to the impact event could reveal if it took a long time to develop diverse fur patterns, or if they began before the dinosaurs’ demise. Ultimately, similar studies could help determine whether the extinction of dinosaurs was necessary for the rise of mammals.

Environmentalists renew calls for windfall tax to support households after Q2 earnings rise to almost $10bn

Shell has posted its second highest quarterly earnings on record as the energy market surge caused by the Middle East crisis helped to double its net profit to almost $10bn in the three months to June.

Europe’s biggest oil and gas company reported a quarterly profit of $9.8bn (£7.4bn), more than double the figure for the second quarter last year and the highest since its record-high earnings in the months after Russia’s invasion of Ukraine.

The Department of Transportation is proposing to exempt commercial space launch licensing from many environmental regulations, a move praised by industry but criticized by environmental groups.
