Inside Cambridge's Ray Dolby Centre where history could be made
The Ray Dolby Centre is as different to the original Cavendish Laboratory as a building can be. Canopies covered in copper fish scales hang above the staircases and exhibits of famous instruments are displayed in glass cases. Away from the entrance lies a warren of 173 laboratories. In many, the air is constantly filtered, light is controlled and there is no vibration.
These controls are vital to the experiments now conducted here, but Dr Dave Ellis, head of nanofabrication, says those sensitivities also made moving the laboratory much harder."Some equipment, like the optics tables, can't be tilted at all, so there were rough patches of road which we had to resurface to make the journey smooth," he says. "The removals company also developed new techniques to ensure the lorries stayed stable when the equipment was moved. "Everyone went to great lengths to make it a success."
In one of the new labs, PHD student Sarah Sibug-Torres is trying to develop a toilet that uses gold and lasers to analyse urine - a process called Surface-enhanced Raman spectroscopy. "Everyone uses a loo," says Ms Sibug-Torres, "but not everyone realises the urine we flush away contains thousands of different types of molecules."[They] can give clues about whether someone is developing disease or responding to medication, for example. "Each type of molecule vibrates in a different way, so, unlike with a traditional urine dip test, we can identify these molecules even in very low concentrations."Ms Sibug-Torres hopes her work will enable early diagnosis and better all-round health in future.
Other teams at the Cavendish are working on ways to use light to improve endoscopic tests for oesophageal cancer.They are also creating components to help the CERN Collider in Switzerland, which aims to detect new particles furthering our understanding of dark matter in space. Dr Stefan Diesing is developing new solar panels to power the satellites that we rely on in space for GPS, communication and earth monitoring."In space, unlike on earth, there's no magnetic field to shield you against all the things that are whizzing around," he explains. "Those particles can damage the solar panels, so they don't last as long. "We're developing a much more resilient material which is also very thin."Dr Diesing says these new panels could one day enable solar farms in space, which capture energy and beam it back for use on earth.
The building has been designed so research teams collaborate more and share ideas. The head of the Cavendish Laboratory, Prof Mete Atatüre, says interaction is critical but it was much harder in the old building."I loved the old lab, but it prioritised lab space over everything else," she explains."Here, you bump into people all the time and discuss your work - and that can lead to something else."While some features are deliberately different to the previous lab, others protect tradition. In the coming weeks, some of the old blackboards will be installed. Prof Atatüre insists it is important that scientists still work through problems by "getting chalk on their hands", much like their predecessors.
In addition to funding from the University of Cambridge, the Ray Dolby Foundation gave £85m to the project. Ray Dolby was a PHD student in Cambridge in the 1950s and went on to invent the world famous surround-sound system that transformed music and movies from the late 1970s. The government has also provided £75m to keep the building as a national resource open to scientists from across the UK.It is also expected to inspire both students and the public alike.With the Cavendish Laboratory being home to 31 Nobel Prize winners, it is hoped this new facility will soon have a few history-makers of its own.

Giant Galapagos tortoise aged 30 and the world's largest rodents among animals in London Zoo's annual weigh-in
A 30-year-old giant Galapagos tortoise named Priscilla and a pair of the world's largest rodents were among more than 10,000 animals at London Zoo's annual weigh-in. London Zoo is home to 4,000 different animal species that are all weighed and measured on a regular basis to monitor their health, development and identify pregnancies. Zookeepers use different training methods or techniques to get individual animals to step on to the scales - Priscilla was lured onto a board scale with a lettuce snack. A pair of capybaras, Humboldt penguins, and a ring-tailed lemur troop were also among the animals to step on the scales. Tint Darwin's frogs weighed in as one of the Zoo's smallest creatures, measuring just two centimetres in length, and under two grams in weight. London Zoo's animal operations manager Daniel Simmonds said: 'The London Zoo Annual Weigh In is not just about numbers on a scale; regular weigh-ins help zookeepers track the health of our animals - including the capybaras, tortoises, and penguins - and genuinely help us manage the care of these animals, who play a vital role in our global conservation efforts.' Many of the zoo's animals are trained to perch on a scale while zookeepers note down their measurements. Meanwhile, for some, scales may be placed in doorways or disguised in their habitats, meaning the animal can be weighed without realising. The zoo says that their weigh-in is an opportunity to ensure the information recorded for each individual is up-to-date and accurate. Each measurement is added to the Zoological Information Management System (ZIMS), a database shared with animal carers and conservationists all over the world. This helps experts to compare important information on thousands of endangered species. Daniel added: 'Our animals here at London Zoo receive world-class care - and a huge part of this is our meticulous planning of their diets. 'Our zoo-tritionist ensures every animal is getting the nutrients they need, while our keepers devise ways to feed the animals that spark all of their natural instincts - keeping them fit and challenged.'

London Zoo begins its annual animal weigh-in
It's that time of year again, when keepers at London Zoo weigh and measure hundreds of animals as part of a yearly of the animals' measurements are recorded in a database called the Zoological Information Management System. It helps zookeepers all over the planet compare important information on thousands of endangered with so many animals, it's not always an easy task to carry out! Let's take a closer look at how it all went. Every mammal, bird, reptile, fish and invertebrate across the zoo is weighed and measured. This capybara needed some tasty treats to be convinced to step onto the scales! These cheeky Humboldt penguins couldn't wait to get on the scales! The penguins are native to the rocky coastal shores of Peru and Chile in South America and are listed as vulnerable to extinction by the International Union for the Conservation of Nature (IUCN). Normal kitchen weighing scale were used to measure this giant hooded katydid. Did you know these impressive insects are not only known for their large size - but they are also able to camouflage themselves as leaves, which helps them hide from potential predators. Animals of all ages and sizes were measured. Priscilla is London Zoo's 30-year-old giant Galapagos tortoise. They are the largest living species of tortoise in the world, and can weigh more than 400kg and survive without food or water for over a year! London Zoo's animals, such as this Vietnamese land snail, are weighed and measured on a regular basis. This helps keepers monitor their health, wellbeing and development. And finally, check out these playful ring-tailed lemurs who look like they're enjoying the attention and having a lot of fun! These primates live in troops of up to 30 individuals and are known for being very social and vocal animals.

Calls for ‘landscape-wide' action to protect butterflies amid falling numbers
Conservationists have called for 'landscape-wide' action to protect butterflies, as new official figures indicate declines of nearly a fifth since the 1970s. The latest annual update on butterfly monitoring published by the Environment Department (Defra) reveal abundance across all butterfly species has declined 18% in the UK and 19% in England over the long-term. The situation is even worse for specialists which need specific habitats such as flower-rich grassland, heathland and woodland clearings to thrive, with numbers declining by more than a third (39%) across the UK, and 25% in England. And some individual species of butterflies have seen numbers plummet by more than 80% since 1976, the monitoring suggests. Conservationists warn falls in the abundance of butterflies are a signal of problems in the wider environment, and reveal what is happening to many other insects that are a key part of ecosystems. The latest figures include 2024, which wildlife charity Butterfly Conservation's head of science Dr Richard Fox described as a 'terrible year for the UK's butterflies'. May last year was the warmest on record, but had notably low levels of sunshine, and overall 2024 ranked as the fourth warmest and eighth wettest year since the early 1900s, disrupting seasonal patterns essential to many butterfly species. The weather conditions hit butterflies which were already struggling with habitat loss and pollution, conservationists warn. Dr Fox said: 'With the addition of data from 2024, which was a terrible year for the UK's butterflies, these updated indicators reiterate the long-term decline of these beautiful insects. 'In particular, habitat specialists – butterfly species that rely on specific habitats such as heathland, woodland clearings or flower-rich grassland – have fared poorly since the 1970s as humans have destroyed and polluted these habitats. 'When we also factor in the implications of climate change, which is resulting in unpredictable extremes of weather, it is more important than ever that we take conservation action on a landscape-wide scale.' The data indicate nearly half (46%) of individual species that are restricted to certain habitats have seen declines in the UK, while 50% have seen numbers fall in England. Across the UK, heath fritillary has seen the most severe declines since 1976 with an 89% drop in abundance, while other habitat specialists including wood white, small-bordered fritillary, grayling and pearl-bordered fritillary have seen declines of 70% to 80%. The assessment from Defra said the main causes for the declines in habitat specialist butterflies were the loss, fragmentation and degradation of those landscapes, with more intensive agriculture also contributing to the drop in numbers. Many have not recovered from declines experienced in the late 1970s, which were partly as a result of the knock-on effects of the drought conditions in 1976, but a lack of suitable habitat after that is the main driver for persistent declines and lack of recovery since, it said. Butterflies found on farmland have declined by around a third in both the UK and England, with those that require the specific habitat to thrive seeing falls in abundance of 42% in the UK and 47% in England. Woodland butterflies have fared even worse with declines of more than half (54%) since the 1970s when monitoring began, with woodland specialist species declining by 55% in the UK and 57% in England. Butterflies have also seen short-term declines on farmland, with numbers falling 12% across the UK and 11% in England over the past decade, the figures suggest, while woodland butterflies have shown no significant change over the same period. But the findings also indicate some specialist species are on the increase, including black hairstreak, silver-spotted skippers, large heath, dark green fritillary, silver-washed fritillary and purple emperor. Officials said some recent increases could be attributed to targeted conservation action, while some species are benefiting from climate change which is allowing them to expand their range. Dr Fox urged: 'Looking at the specific conditions these species need to thrive and working to reinstate them where we can will offer some of these very vulnerable species an opportunity to recover.' Across more 'generalist' species, which are not restricted to specific habitats, there has been no change over the long or short-term, but the fortunes of individual species have differed wildly. Small tortoiseshell butterflies have seen falls of 86% between 1976 and 2024, while wall and white-letter hairstreak butterflies have seen almost as severe declines. But ringlet butterflies have increased by 273%, and holly blue and comma butterflies have also seen some of the largest increases in abundance over five decades, the figures suggest. Across the 50 species monitored across the UK, 44% have suffered declines since 1976, while 47% of the 49 species assessed in England have seen drops since then. Some 28% of individual species have increased across the UK and 24% have increased in England, the statistics indicate.
