Ladybirds being seen in ‘very high numbers' because of warm weather, expert says
England's vice-captain Ollie Pope called it a first in the sport.
'I've never seen that, no,' he said after the match. 'That's a first that the crowd have got that today.'
Ecologist and ladybird expert Professor Helen Roy, from the UK Centre for Ecology and Hydrology, said: 'Many species of aphid-feeding ladybird such as the seven-spot ladybird are being seen in very high numbers this year.
'This is a consequence of the high aphid numbers and warm weather.
'People are reporting many sightings to the UK Ladybird Survey through iRecord, which is fantastic.
'If people want to help insects and other wildlife in this weather they can leave shallow dishes with a little water for them. Also, we encourage people to leave the aphids in their garden on roses and other plants so there is plenty of food for ladybirds.'
Tim Coulson, professor of zoology and head of biology at the University of Oxford, encouraged people to 'learn to love' ladybirds.
'Warm weather means more aphids because they can complete each generation faster – insects, including ladybirds and aphids, tend to speed up their lives in warm weather,' he said.
'Ladybirds eat aphids, and an abundance of aphids mean ladybirds have a lot to eat.
'People should learn to love the ladybirds. They are effective predators of aphids, which can be a major pest of many plant species.
'Much in the way that wolves keep deer numbers in check in some parts of the world, ladybirds keep aphid numbers down.
'A swarm of ladybirds in a cricket game, even against India, should remind people of the role that predators play in keeping the ecology of earth in a healthy state.'
Dr Peter Brown, associate professor in ecology and conservation at Anglia Ruskin University, said the last 'boom year' for ladybirds was during the hot summer of 1976, although there have been years in between when there has been a rise but the locations have been more isolated.
'In 1976 there were a lot of seven-spot ladybirds on the beaches as they searched for food and people thought they were invading – they were not, as they are native to the UK,' he said.
Dr Brown, who is an organiser of the UK Ladybird Survey, added that the increase in numbers should be seen as a positive and the current warm conditions were the reason.

Exact date 'hostile alien probe' could strike Earth revealed as Harvard scientist issues chilling warning
A Harvard scientist has issued a chilling warning about a mysterious interstellar object hurtling through our solar system, and says it could spell disaster for Earth. Professor Avi Loeb, who is well-known for pushing bold and often polarizing theories about extraterrestrial life, has been tracking the object, named 3I/ATLAS, since it was first spotted on July 1. If the object is an alien craft, Loeb warned it could be carrying a probe or even a weapon. He predicted that such an intercept vehicle would reach Earth between November 21 and December 5, 2025. The timeline is based on calculations that 3I/ATLAS will pass behind the sun from Earth's perspective this October, a time he ominously suggested could be used to prepare the attack. Referring to the object as a 'mothership,' he explained that its position would be an efficient way to seed habitable planets with probes. This strategy would allow the devices to 'intercept the planets while the mothership continues on its journey to the next star.' 'It may come to save us or destroy us. We'd better be ready for both options and check whether all interstellar objects are rocks,' said Loeb. Chris Lintott, an astronomer at the University of Oxford, has dismissed Loeb's claims as 'nonsense on stilts,' telling Live Science that the alien probe theory is an 'insult to the exciting work going on to understand this object.' Loeb has remained adamant that something about 3I/ATLAS does not add up. He said its retrograde orbit, meaning it's moving against the flow of the solar system, is oddly aligned with Earth's path. '3I/ATLAS might be an alien probe,' he said, citing its 'unusually rare trajectory,' which just so happens to align closely with the orbital plane of the inner planets, including Earth. He puts the odds of that happening naturally at just 0.2 percent. 'At its closest point to the sun on October 29, fears of an alien invasion could send stock markets crashing,' Loeb said. 'In that scenario, citizens would lose their trust in governments to protect them.' He went so far as to compare the potential chaos to a military ambush, saying: 'Facing a high-tech alien visitor could feel like Iran's air defenses when US B-2 bombers appeared, silent, unstoppable, and overwhelmingly powerful.' The object, believed to be about 12 miles wide, is unusually large for something hurtling in from outside the solar system. According to Loeb, if it were natural, we would have already spotted millions of similar objects. 'But we haven't,' he said. He has published three pre-print papers laying out the case and has even suggested that NASA attempt an interception using its Juno spacecraft when the object passes near Jupiter. 'In my view, we need a risk scale for interstellar objects,' Loeb said. 'A zero would be a natural comet. 'A 10 would be a verified technological object, possibly powered by an engine or emitting artificial light.' He also believes governments should already be forming task forces, including scientists, policymakers and even psychologists, to determine how to respond and how to break the news to the public without triggering panic. Loeb's warnings have grown increasingly urgent, culminating in one dramatic statement: 'It may come to save us or destroy us. We'd better be ready for both options.' If 3I/ATLAS is more than just a rock, he said Earth is woefully unprepared. 'The visitor,' he warned, 'is already in our backyard.' Even if the object turns out to be artificial, Loeb admitted there's little humanity could do. At nearly 60 miles per second relative to Earth, it's moving far too fast for any of our current rockets to reach. 'If the hypothesis that 3I/ATLAS is a technological artifact proves correct, there are two possible implications: either its intentions are entirely benign, or they are malign, said Loeb. 'In the first case, humanity need only wait and welcome this interstellar messenger with open arms. It is the second scenario that causes serious concern.' He added that because the second possibility has serious consequences, we can use the idea behind Pascal's wager. 'Blaise Pascal argued that it's smarter to believe in God because the possible benefits of believing are much greater than the losses if you're wrong,' Loeb explained. 'Similarly, in our case, it makes sense to warn humanity about the risk from 3I/ATLAS, even if it turns out to be just a theory.

Oxford chemists find honey offering in 2,500 year old shrine
Chemists have identified a residue found in 2,500-year-old bronze jars as honey, solving a "decades-old archaeological puzzle".The discovery was made by the University of Oxford's chemistry department, who reinvestigated jars excavated from a 6th Century BE Greek shrine in Paestum, southern a study published in the Journal of the American Chemical Society, researchers said biomolecular evidence showed the residue was likely in the form of bronze jars were originally found in an underground shrine, an hour and a half's drive away from Pompeii, in 1954. They contained an orange-brown sticky substance archaeologists assumed was honey, as it was often left as an offering to gods or buried alongside the Luciana da Costa Carvalho, project co-lead, said: "This research is a reminder that archaeological collections hold untapped scientific potential and how new information can be revealed when modern analytical techniques and multidisciplinary collaborations are combined." For 30 years, three different teams analysed the residue, but failed to confirm the presence of honey and said it was some sort of animal or vegetable fat contaminated with pollen and insect chemists have used modern techniques to examine the contents of the bronze jar, through a partnership with the University of Oxford's Ashmolean Museum and the Archaeological Park of Pompeii. Professor James McCullagh, director of Oxford's mass spectrometry research facility in the department of chemistry, co-led the project. He said the number of analytical techniques used for the study were "key to the success of this study"."By applying several mass spectrometry and spectroscopic approaches we were able to reveal a comprehensive picture of the residue's molecular composition — enabling us to distinguish between contaminants, degradation products, and original biomarkers," he said.A university statement added that the authors of the study now hoped their work would inspire further re-analysis of legacy materials, including those held in museum collections.

Uranus: Giant ice planet could be warmer than first thought
The planet Uranus is known for being one of two ice giants in the outer solar system and sits in a remote part of the Milky one Nasa spacecraft, Voyager 2, has ever travelled close to it and the planet has long been thought of as a cold and distant could it actually be warmer than we first thought?A new study by scientists suggests that could be true as they think Uranus gives out more heat than it receives from the Sun. What did scientists find? The new study was carried out by a group of experts from Nasa and from the University of Oxford in the decided to take a closer look at the huge planet, which is four times wider than of the reasons scientists don't know much about Uranus is because it's located so far only ever been visited once before, in a brief flyby by the Voyager-2 probe nearly 40 years ago, in from that mission suggested the planet is colder than expected, which challenged ideas of how planets formed and the team decided to use the latest tech and advanced computer modelling and take a fresh new look at the old a result, scientists now think the planet may actually be warmer than previously author Professor Patrick Irwin, from the University of Oxford, explained: "We did many calculations to see how much sunshine is reflected by Uranus and we realized that it is actually more reflective than people had estimated."Researchers found that Uranus releases about 15% more energy than it receives from the Sun, suggesting that it has its own team says that the discovery could help people better understand exoplanets, which are planets located outside the solar system. Five top facts about Uranus 1. Uranus is the seventh planet from the Sun, and the third largest planet in the Milky Way.2. Uranus is unlike any other planet in our solar system. It spins on its side, which means each pole directly faces the Sun for around 42 years at a time, followed by 42 years of complete darkness.3. Uranus has two sets of rings. The inner group of nine rings is mostly made up of narrow, dark grey rings. There are also two outer rings: the innermost one is reddish in colour, and the outer ring is blue.4. Uranus is one of just two planets in our solar system that rotate in the opposite direction to all the rest of the planets in the Milky Way - the other one being Venus.5. According to Nasa, Uranus gets its blue-green colour thanks to methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus' cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green colour.
