Blow to the LHC "bump", Crow intelligence, Robot mudskippers, Royal Society book prize

New results have squashed the hope that the hints of a new particle detected by the Large Hadron Collider would confirm the existence of something extremely exotic, such as a new Higgs, or even the theoretical Graviton. Instead, the intriguing data 'bump' turns out to be nothing more than a statistical fluctuation. Physicist Jonathan Butterworth of UCL discusses whether this false alarm affects the LHC's chances of finding something else.Crows, ravens and other members of the bird family we call Corvids are well known to have sophisticated skills in tool use and problem solving. Research out this week reports ravens bending wire to help forage for their food. But what constitutes intelligence in bird brains? Adam Rutherford visits the Tower of London where ravens have been permanent residents since the 16th Century, and so quite a good spot for scientists to go and put bird brains to the test. He meets Sophie Hamnett and Nathan Emery from Queen Mary, University of London.Animals evolved in the seas, but by about 400 million years ago, some fishy creatures had evolved to begin walking on terra firma. Nowadays we look at creatures like mudskippers, that can swim and wade, to see how those first crawlers might have crept up the beach. A new study has gone one step further: Jonathan Webb went to Georgia Tech in Atlanta to meet the robot mudskippers.We're profiling each of the shortlisted books for the Royal Society book prize this year, and this week it is the turn of oncologist Siddartha Muhkerjee. He has turned his attention to trying to understand the root of all cancers, and the mental health issues his own family endure. His new book, The Gene, details the central concept in inheritance.Producer Adrian Washbourne.

Signs of life on planets, Royal Society Book Prize, Queen Bee control, Galactic Prom 29

What should we be looking for when searching for life on other planets beyond our solar system? Scientists urgently need to come to a consensus on this as a new suite of telescopes soon begins detecting. The space agency NASA has put together a virtual institute called The Nexus for Exoplanet System Science, and they've just met to work out how we should be looking for bio signatures - on the burgeoning catalogue of worlds beyond the Solar System. Adam Rutherford hears from Sarah Rugheimer, an astrobiologist from the University of St Andrews, on why the world's astrobiologists have decided to lay down the law.The Royal Society Insight Investment Book Prize celebrates some of the best science published each year. Today the judges announced their shortlist: The Cure by Jo Marchant; The Gene by Siddhartha Mukherjee; The Hunt for Vulcan by Thomas Levenson; The Invention of Nature by Andrea Wulf; The Most Perfect Thing by Tim Birkhead; The Planet Remade by Oliver Morton. We're talking to all the authors over the next 6 weeks before the winner is announced on the 19th of September. The first is Oliver Morton's The Planet Remade: How Geoengineering Could Change the World.Bee hives have evolved to have a complex, fascinating social hierarchy, and although we know about Royal Jelly and pheromones, how exactly does the queen bee control the fertility of the rest of the hive? A team of New Zealand geneticists, Peter Dearden and Elizabeth Duncan, has finally worked it out.This Saturday's evening BBC Prom is set in space. The National Youth Orchestra performs The Planets by Holst, and Richard Strauss' Also Sprach Zarathustra. But the concert begins with a piece inspired by this year's detection of Gravitational Waves by LIGO, the Laser Interferometer Gravitational-Wave Observatory. Gravitational Waves composer Iris Ter Schiphorst discusses how she went galactic.Producer: Adrian Washbourne.

Dinosaur extinction, Neanderthals in Gibraltar, Music appreciation, A year of New Horizons

The dinosaurs met their end with a massive bang when, 66 million years ago, a 6 mile-wide rock crashed into the Gulf of Mexico. This was bad news for the dinosaurs, and consequently good news for the mammals left behind. Thomas Halliday is a palaeontologist, who specialises on the rise of the mammals, and his new work unpicks what happened to survivors after 75% of the species on earth died. The Neanderthals were found in Gibraltar back in 1848. Ever since then, teams have been exploring the caves systems on that rocky outcrop of Europe. It's known as Neanderthal City and researchers think it was home to the very last of these people, some 30,000 years ago. BBC science reporter Melissa Hogenboom has just returned from Gibraltar and talks to Adam about the recent findings of abstract art, which suggest that Neanderthals are much more like us than previously thought.We generally find the combination of notes in a consonant chord more pleasant to our ears than a dissonant one. The question is whether that reaction is learnt or simply part of our biology. It's a tricky thing to test because music is culturally ubiquitous. Neuroscientist Josh McDermott has found a way around this, by playing those tunes to members of a very remote Bolivian tribe - the Tsimane - and gauging their reactions.One year on since the New Horizons probe zoomed past Pluto, Kathy Olkin, one of the chief scientists behind the mission talks to Adam about how the team have dealt with the new data. Noah Hammond from Brown University explains how he has used photographic data from New Horizons to examine the cracks in the surface of Pluto, and has suggested how they came to be.Presenter: Adam RutherfordProducer: Adrian Washbourne.

Juno, Space debris, Fake tumours, Risky plants

Earlier this week, the US space agency successfully put a new probe in orbit around Jupiter. The Juno satellite, which left Earth five years ago, had to fire a rocket engine in a tricky and precise manoeuvre in order to brake and become ensnared by Jupiter's gravity. Fran Baganal is a mission scientist for Juno and tells Adam Rutherford what measurements Juno is now in position to make.Space is full of junk left over from past space missions: from flecks of paint to used rockets, dead satellites, also debris from past collisions of space junk. This junk is speeding around the Earth at several thousand miles per hour. At those speeds even small pieces of rubbish just fractions of a millimetre across can damage communication satellites which are vital for the web, mobile phones, and satellite navigation on earth. The Surrey Space centre team are preparing to launch the world's first space litter-picking mission. The RemoveDebris team share their clean up designs with Adam.Researchers have had success growing body parts like windpipes and ears in the laboratory for use in transplants. A group of scientists at Barts Cancer Institute in London are making own tumours; tissues we don't want. However, it is important to study how they grow, and co-opt other cells in the body. Reporter Anand Jagatia heads to their tissue lab to see what they've grown.All animals take risky decisions all the time. The ability to assess the potential gain from the potential harm, and make the right choice, gives the animal an evolutionary advantage. A new study suggests that plants are capable of making similar calculations, despite not having brains. Alex Kacelnik at Oxford University is one of the scientists behind the experiment that suggests that pea plants are willing to gamble.Presenter: Adam RutherfordProducer: Adrian Washbourne.

Juno, Nanotech art conservation, Robots fix the city, Eel conservation

NASA's Juno Probe arrives at Jupiter on 4th July, where it will execute a daring loop-the-loop in order to get closer to the giant planet than any other spacecraft in history. Juno is constructed like an armoured tank, because Jupiter is surrounded by a belt of very intense radiation that can quickly fry most spacecraft electronics. On July 4, Juno's engines will attempt to slow the probe down so it can be sucked into Jupiter's orbit. The slightest error could mean Juno misses this window, putting an end to the $1.1 billion mission. The man in charge is Dr Scott Bolton, and he speaks to Adam from Pasadena in California.Traditional art conservation tends to focus on paintings - how to stop paint from peeling. But contemporary art uses a much broader range of materials; plastics, rubber; pickled sharks. This means that an ever-increasing array of techniques are needed to conserve those materials. A new project is looking at the role nanotechnology can play, as Rob Thompson reports.It's National Robot Week. There is a fear that robots will replace many of the jobs done by humans. But what if robots just stuck to emptying the gutters and fixing potholes; the chores that humans find tedious? Professor Phil Purnell from Leeds University has just launched a project that aims to use robots to fix bits of the city - finding and patching tiny defects before they turn into massive sinkholes.The European eel may be mysterious, and delicious but it is also critically endangered. The only reason we know this is because of organisations like the Zoological Society of London. They do the unglamorous job of monitoring these fish caught in traps in rivers around the UK. Marnie Chesterton went along to count eels in rainy Brentford with ZSL's Joe Pecorelli, who shares his knowledge of this creature's epic life journey.

National Insect Week, Venus' electric field, Green mining, Wimbledon grass science

This week is National Insect Week. Almost all animals on Earth are insects, and entomologist Adam Hart told us why we're celebrating and studying them in such detail - particularly diamondback moths, which have recently arrived the UK in large numbers. On the first official (and rather rainy) day of summer, we went down to Butterfly Paradise at London Zoo for the event launch. Entomologist Adam Hart tells us what the Week is all about.New research out this week suggests that a so called "electric wind" has stripped all the water away from the surface of Venus. Space scientist Glyn Collinson at NASA Goddard Space Flight Centre has led this electrical field study.Wales has 1300 rivers with illegal levels of heavy metals. Toxic metals like lead, zinc and copper are a legacy left over from when the area was heavily mined. Natural Resources Wales and Innovate UK set a competition to look for technology that would clean up these rivers. One of the winners was Steve Skill from Swansea University, who has come up with some biotechnology that uses algae to suck the poison out of the rivers.The Championships at Wimbledon start next week, and whatever the weather, the grass has to be perfect. Adam Rutherford headed to London's SW19 to find out how the ground staff are using scientific evidence to cultivate the courts.Producers: Marnie Chesterton & Jen Whyntie.

More gravitational waves; Ocean floor mapping; Selfish Gene 40th; Spoonies

Gravitational waves have been detected for a second time. These waves are ripples in the curvature of space time, predicted by Einstein in his General Theory of Relativity in 1916. Back in February, the Laser Interferometer Gravitational-Wave Observatory (better known as LIGO) announced that they had detected the signal of gravitational waves from the collisions of two big black holes. The detection in February was the first observation of these waves, and confirmed General Relativity. This week, LIGO confirm a second detection. BBC Science Correspondent Jonathan Amos explains what is new about these new gravitational waves. We know more about the surface of the moon than we know about the ocean floor. Admittedly, the sea is much more dynamic, the scene of many chemical and biological processes, about which scientists would like to learn more. This week, cartographers meet in Monte Carlo, to discuss their plan to map the ocean floor by 2030. Roland Pease reports on the ocean-mapping options. 40 years ago, The Selfish Gene, by Richard Dawkins was published. Since then, it has been a perpetual bestseller. In it, Dawkins explains that the gene is the unit of natural selection, an idea that has become central to all biology. Adam Rutherford speaks to Richard Dawkins, and his co-author on ‘The Ancestor’s Tale’ Yan Wong, at the Cheltenham Science Festival, to discuss the impact of The Selfish Gene.The spoonbilled sandpiper is standing on the edge of extinction, but in good news, Adam hears about of a clutch of eggs laid not in their native Russia but in Slimbridge in Gloucestershire. BBC producer Andrew Luck-Baker visited the Wildfowl and Wetlands Trust’s population back in April, and describes these birds to Adam.

Fighting Antimicrobial Resistance

This week we're dedicating the whole programme to one of the biggest threats to humanity. We're already at 700,000 preventable deaths per year as a result of antibiotic resistance, and the O'Neill Report suggests that this will rise to 10 million people per year by 2050. Today, we're focussing on the attempts to discover new antibiotics, and alternative therapies for combating bacterial infection. Firstly, we wanted to know why new antibiotics aren't being produced. Dr Jack Scannell, an expert on the drug development economics, told Adam Rutherford why money has been the main barrier.Most of the antibiotics we use were discovered in the mid-20th century, but as the threat of drug resistant infections increases, the race is on to find new organisms that make novel medicines. We have only identified a tiny fraction of the microbes living on Earth and are "bioprospecting" for useful ones in wildly different locations. Microbiologist Matt Hutchings has been looking to the oldest farmers in the world - leaf cutter ants.From exotic locations to under your fridge: Dr Adam Roberts runs a scheme called Swab and Send. It's a citizen science project that asks members of the public to swab a surface and send the sample to him – he'll analyse them to look for the presence of new antibiotic-producing bacteria. We joined in the hunt by swabbing spots around the BBC: Adam's microphone, the Today programme presenters' mics, our tea kitchen's sponge, the revolving entryway doormat, and lastly, the Dalek standing on guard outside the BBC Radio Theatre.Antibiotics are not the only weapon in the war against bacteria. A hundred years ago, a class of virus that infect and destroy bacteria were discovered. They're called bacteriophages. Phage therapies were used throughout the era of Soviet Russia, and still are in some countries, including Georgia. Phage researcher Prof Martha Clokie told us whether phage therapy might be coming to the UK.

Fixing the Future

We face many global problems, such as drought, flooding and climate change. All of these issues are rooted in science. It'll take politics and people and business to fix them, or for us to manage them, but none of that can happen without a solid scientific base.In front of an audience at the Hay Festival, Adam Rutherford is joined by Steve Jones, Professor of Genetics at University College London, Marcus du Sautoy, the Simonyi Professor of the Public Understanding of Science at the University of Oxford, and science journalist, Gaia Vince, to discuss what the future holds for humanity and the planet, what we can know, what we can predict, and what is to come.Adam Rutherford talks to Gaia Vince about the new age of man, the Anthropocene, and the impact it is having on peoples' lives, to Marcus du Sautoy about chaotic systems and when maths can and cannot predict the future, and to Steve Jones about forecasting human population growth and how we are still evolving.

GM plants; Svalbard Seed Vault; Directed Evolution; Dolphin Snot

The topic of GM plants raises strong opinions and many questions. This week, the Royal Society published answers to some of those questions. Adam speaks to Professor Ottoline Leyser, plant science expert and Head of the Sainsbury Lab in Cambridge. She was involved in writing the responses and Adam quizzes her on the possible issues with GM crops.Institutes from around the world made deposits to the Svalbard Global Seed Vault this week. More than 8,000 varieties of crops from Germany, Thailand, New Zealand, and the World Vegetable Center arrived at the Vault, located on a remote Norwegian archipelago, to be stored deep within the permafrost. Reporter Marnie Chesterton was there to see it happen, and take a tour of this normally inaccessible place. The Vault is located within the Arctic Circle, and helps to protect the biodiversity of some of the world’s most important crops against climate change, war and natural disaster. This week Professor Frances Arnold was awarded the Millennium Technology Prize; the Finnish version of the Nobel Prize. Her work is a process called Directed Evolution, and involves creating batches of mutant proteins to see if the mutations make them better at certain functions. Dolphins use ultrasound to echolocate. Until recently, scientists did not quite know how. Making ultrasonic noises normally requires some hard surfaces such as metal, and dolphins don’t have metal in their blowholes. Acoustic scientists Aaron Thode at the Scripps Institute of Oceanography in San Diego thinks he’s solved this conundrum, and it involves snot. Producer: Jen Whyntie
