Group says move would allow shoots to be banned if birds of prey are illegally killed, amid withdrawal from hen harrier scheme
Grouse shooting estates should be licensed so that authorities have the power to ban them if birds of prey are illegally killed, the RSPB has urged, as it quit a government initiative to save the hen harrier in England.
The hen harrier action plan is a Department for Environment, Food and Rural Affairs-led scheme in which landowners, shooting groups and conservation organisations agreed to work together to increase numbers of hen harriers in England.

The Bollywood star Salman Khan has been acquitted of shooting and killing three endangered animals nearly two decades ago, a verdict that overturned a lower court's ruling that would have sent the actor to jail.
Khan and seven other people, including Bollywood actors, had been accused of killing a gazelle and two antelopes over two days in 1998 while filming a movie in Rajasthan state.

A new study of old masters finds that capturing and showing off decadent and expensive meals is a decidedly old-fashioned practice. Like today's Instagrammers, it was all about projecting an image.
In the 1980s, I remember that many scientists feared that ozone depletion was irreversible and the headlines in many newspapers declared that nations were powerless to stem the growing loss of ozone - the great hole in the ozone that threatened us all. But the Montreal Protocol proved that the pessimists and the naysayers were wrong. Virtually all the parties have met their obligations under the accord. Nearly 100 of the most ozone-depleting substances have been phased out. And as a result, the hole in the ozone is shrinking and on its way to repair. It's why we're here today... Now, that's the good news. The bad news is that in too many cases, the substances banned by the Montreal Protocol have been replaced by hydrofluorocarbons - HFCs - which are safer for ozone, but are exceptionally potent drivers of climate change - thousands of times more potent, for example, than CO2.
The Montreal treaty allows nations to amend it to ban substitute chemicals that have negative environmental effects even if they do not harm the ozone. And American chemical companies such as Dow, DuPont and Honeywell have already begun to patent climate-friendly HFC substitutes.

‘Robot Wars' returned to our screens last night after a 12-year absence - and, for many, it was as though it had never been away.
The geeks' delight drew an audience of two million viewers, representing a 10% share and, pointedly, a fair few more than tuned in for the beleaguered ‘Top Gear' series finale.
Three weeks ago, ‘Top Gear's final show of six drew 1.9million viewers, and lead presenter fell on his sword the following day.
Judging by the positive reviews so far for the techy reboot, it looks as though hosts Dara O'Briain and Angela Scanlon and resident warriors Sir Killalot, Matilda, Dead Metal and Shunt, will enjoy a far smoother run.
Critics and viewers praised the mix of old and new elements of the show, the robots re-booted, the hosts replaced but the participants' attention to detail, the fans' devotion, the pyrotechnics all upstanding and present. If it ain't broke, and all that...
Books, puzzles, pantomime programmes and other rare items among hoard, the gift of an eccentric American collector
A small army of Dick Whittingtons and a tribe of cats have arrived at the Guildhall library in London, which was founded using the real medieval mayor's legacy, in a bequest from an eccentric American collector.
The treasury includes books, games and puzzles, glass magic lantern slides, pantomime programmes and posters, and a unique copy of a tiny hand-coloured early 19th-century book. All are related to the legend of the poor boy leaving the city in despair until he heard the sound of Bow Bells, and was urged by his cat to turn back and make his fortune and thrice become mayor of London.

Adam and Eve are once again as naked as the day they were created, centuries after some prudish hand wrapped his loins in a grass skirt and draped a veil around her, in an illustrated book to go on display at the Fitzwilliam Museum in Cambridge.
The original naked figures correct according to the biblical account where Adam and Eve only became ashamed of their bare bodies when they ate the forbidden fruit and were expelled from the Garden of Eden were considered perfectly suitable by Queen Anne of Brittany in 1505, who commissioned the book as a gift for her five-year-old daughter, Claude. The book, made by a court painter known as the Master of Antoine de Roche, was created to teach the little princess the alphabet as well as the story of creation.

Using NASA's Hubble Space Telescope, astronomers at the University of Arizona captured the first direct, time-resolved images of an exoplanet, a young, gaseous exoplanet known as 2M1207b, shown above, located some 160 light-years from Earth. The planet is four times the mass of Jupiter and orbits a failed star, known to astronomers as a brown dwarf. And while our solar system is 4.5 billion years in the making, 2M1207b is a mere ten million years old. Its days are short--less than 11 hours--and its temperature is hot--a blistering 2,600 degrees Fahrenheit. Its rain showers arrive in the form of liquid iron and glass.
"2M1207b is likely just the first of many exoplanets we will now be able to characterize and map," said Steward Observatory astronomer Glenn Schneider who co-authored the study with Lunar and Planetary Laboratory's Adam Showman released this February 16, 2016.The composite image above shows the exoplanet (the red spot on the lower left), orbiting the brown dwarf 2M1207 (center). 2M1207b is the first exoplanet directly imaged and the first discovered orbiting a brown dwarf. It was imaged the first time by the VLT in 2004. Its planetary identity and characteristics were confirmed after one year of observations in 2005. 2M1207b is a Jupiter-like planet, 5 times more massive than Jupiter.
The alien planet orbits the brown dwarf at a distance 55 times larger than the Earth to the Sun, nearly twice as far as Neptune is from the Sun. The system 2M1207 lies at a distance of 230 light-years, in the constellation of Hydra. The photo is based on three near-infrared exposures (in the H, K and L wavebands) with the NACO adaptive-optics facility at the 8.2-m VLT Yepun telescope at the ESO Paranal Observatory.
The researchers, led by UA Department of Astronomy graduate student Yifan Zhou, were able to deduce the exoplanet's rotational period and better understand its atmospheric properties--including its patchy clouds--by taking 160 images of the target over the course of ten hours. Their work was made possible by the high resolution and high contrast imaging capabilities of Hubble's Wide Field Camera 3.
"Understanding the exoplanet's atmosphere was one of the key goals for us. This can help us understand how its clouds form and if they are homogenous or heterogeneous across the planet," said Zhou.
Before now, nobody had ever used 26-year-old Hubble to create time-resolved images of an exoplanet. Even the largest telescope on Earth could not snap a sharp photo of a planet as far away as 2M1207b, so the astronomers created an innovative, new way to map its clouds without actually seeing them in sharp relief: They measured its changing brightness over time.
Daniel Apai, UA assistant professor of astronomy and planetary sciences, is the lead investigator of this Hubble program. He said, "The result is very exciting. It gives us a new technique to explore the atmospheres of exoplanets."
According to Apai, this new imaging technique provides a "method to map exoplanets" and is "an important step for understanding and placing our planets in context." Our Solar System has a relatively limited sampling of planets, and there is no planet as hot or as massive as 2M1207b within it.
"Do these exotic worlds have banded cloud patterns like Jupiter? How is the weather and climate on these extremely hot worlds similar to or different from that of the colder planets in our own solar system? Observations like these are key to answering these questions," said Showman.
Zhou and his collaborators began collecting data for this project in 2014. It began as a pilot study to demonstrate that space telescopes like Hubble and the James Webb Space Telescope, which NASA will launch in late 2018, can be used to map clouds on other planets.
The success of this study lead to a new, larger program: Hubble's Cloud Atlas program for which Apai is also the lead investigator. As one of Hubble's largest exoplanet-focused programs, Cloud Atlas represents a collaboration between 14 experts from across the globe, who are now creating more time-resolved images of other planets using the space telescope.

Are we facing imminent doom? Will the universe collapse? That disparity between theory and observation indicates the Standard Model theory of a constantly expanding universe has been outpaced by new measurements of the Higgs and top quark. A stable universe is one in a low energy state where particles and forces interact and behave according to theoretical predictions forever. That's in contrast to metastable, or unstable, meaning a higher energy state in which things eventually change, or change suddenly and unpredictably, and that could result in the universe collapsing. The Higgs and top quark are the two most important parameters for determining an answer to that question. Recent measurements of the Higgs and top quark indicate they describe a universe that is not stable at all energies.
“It's going to take some work for theorists to explain this,” Kehoe said, adding it's a challenge physicists relish, as evidenced by their preoccupation with “new physics” and the possibilities the Higgs and Top quark create. “I attended two conferences recently and there's argument about exactly what it means, so that could be interesting.”
So are we in trouble? “Not immediately,” Kehoe said. “The energies at which metastability would kick in are so high that particle interactions in our universe almost never reach that level. In any case, a metastable universe would likely not change for many billions of years.”
“The ability to measure the top quark mass precisely is fortuitous because it, together with the Higgs boson mass, tells us whether the universe is stable or not,” said Robert Kehoe, a physicist at Southern Methodist University. “That has emerged as one of today's most important questions.”
“We want a theory — Standard Model or otherwise — that can predict physical processes at all energies,” Kehoe added. “But the measurements now are such that it looks like we may be over the border of a stable universe. We're metastable, meaning there's a gray area, that it's stable in some energies, but not in others.”
In the post-Big Bang world, nature's top quark — a key component of matter — is a highly sensitive probe that physicists use to evaluate competing theories about quantum interactions. Physicists at Southern Methodist University have achieved a new precise measurement of a key subatomic particle, opening the door to better understanding some of the deepest mysteries of our universe.
The researchers calculated the new measurement for a critical characteristic — mass — of the top quark. Quarks make up the protons and neutrons that comprise almost all visible matter. Physicists have known the top quark's mass was large, but encountered great difficulty trying to clearly determine it.
The newly calculated measurement of the top quark will help guide physicists in formulating new theories, said Kehoe, who lead the SMU group that performed the measurement.
Top quark's mass matters ultimately because the particle is a highly sensitive probe and key tool to evaluate competing theories about the nature of matter and the fate of the universe. Physicists for two decades have worked to improve measurement of the top quark's mass and narrow its value.
“Top” bears on newest fundamental particle, the Higgs boson. The new value from SMU confirms the validity of recent measurements by other physicists, said Kehoe. But it also adds growing uncertainty about aspects of physics' Standard Model.
The Standard Model is the collection of theories physicists have derived — and continually revise — to explain the universe and how the tiniest building blocks of our universe interact with one another. Problems with the Standard Model remain to be solved. For example, gravity has not yet been successfully integrated into the framework.
The Standard Model holds that the top quark — known familiarly as “top” — is central in two of the four fundamental forces in our universe — the electroweak force, by which particles gain mass, and the strong force, which governs how quarks interact. The electroweak force governs common phenomena like light, electricity and magnetism. The strong force governs atomic nuclei and their structure, in addition to the particles that quarks comprise, like protons and neutrons in the nucleus.
The top plays a role with the newest fundamental particle in physics, the Higgs boson, in seeing if the electroweak theory holds water. Some scientists think the top quark may be special because its mass can verify or jeopardize the electroweak theory. If jeopardized, that opens the door to what physicists refer to as “new physics” — theories about particles and our universe that go beyond the Standard Model. Other scientists theorize the top quark might also be key to the unification of the electromagnetic and weak interactions of protons, neutrons and quarks. In addition, as the only quark that can be observed directly, the top quark tests the Standard Model's strong force theory.
“So the top quark is really pushing both theories,” Kehoe said. “The top mass is particularly interesting because its measurement is getting to the point now where we are pushing even beyond the level that the theorists understand. Our experimental errors, or uncertainties, are so small, that it really forces theorists to try hard to understand the impact of the quark's mass. We need to observe the Higgs interacting with the top directly and we need to measure both particles more precisely.”
The new measurement results were presented at the Third Annual Conference on Large Hadron Collider Physics, St. Petersburg, Russia, and at the 8th International Workshop on Top Quark Physics, Ischia, Italy.
“The public perception, with discovery of the Higgs, is ‘Ok, it's done,'” Kehoe said. “But it's not done. This is really just the beginning and the top quark is a key tool for figuring out the missing pieces of the puzzle.”
The results were made public by DZero, a collaborative experiment of more than 500 physicists from around the world. The measurement is described in “Precise measurement of the top quark mass in dilepton decays with optimized neutrino weighting” and is available online at arxiv.org/abs/1508.03322.
To narrow the top quark measurement, SMU doctoral researcher Huanzhao Liu took a standard methodology for measuring the top quark and improved the accuracy of some parameters. He also improved calibration of an analysis of top quark data.
“Liu achieved a surprising level of precision,” Kehoe said. “And his new method for optimizing analysis is also applicable to analyses of other particle data besides the top quark, making the methodology useful within the field of particle physics as a whole.”
The SMU optimization could be used to more precisely understand the Higgs boson, which explains why matter has mass, said Liu. The Higgs was observed for the first time in 2012, and physicists keenly want to understand its nature.
“This methodology has its advantages — including understanding Higgs interactions with other particles — and we hope that others use it,” said Liu. “With it we achieved 20-percent improvement in the measurement. Here's how I think of it myself — everybody likes a $199 iPhone with contract. If someday Apple tells us they will reduce the price by 20 percent, how would we all feel to get the lower price?”
Another optimization employed by Liu improved the calibration precision by four times, Kehoe said.
Top quarks, which rarely occur now, were much more common right after the Big Bang 13.8 billion years ago. However, top is the only quark, of six different kinds, that can be observed directly. For that reason, experimental physicists focus on the characteristics of top quarks to better understand the quarks in everyday matter.
To study the top, physicists generate them in particle accelerators, such as the Tevatron, a powerful U.S. Department of Energy particle accelerator operated by Fermi National Laboratory in Illinois, or the Large Hadron Collider in Switzerland, a project of the European Organization for Nuclear Research, CERN.
SMU's measurement draws on top quark data gathered by DZero that was produced from proton-antiproton collisions at the Tevatron, which Fermilab shut down in 2011.
The new measurement is the most precise of its kind from the Tevatron, and is competitive with comparable measurements from the Large Hadron Collider. The top quark mass has been precisely measured more recently, but there is some divergence of the measurements. The SMU result favors the current world average value more than the current world record holder measurement, also from Fermilab. The apparent discrepancy must be addressed, Kehoe said.
As the only quark that can be observed, the top quark pops in and out of existence fleetingly in protons, making it possible for physicists to test and define its properties directly.
“To me it's like fireworks,” Liu said. “They shoot into the sky and explode into smaller pieces, and those smaller pieces continue exploding. That sort of describes how the top quark decays into other particles.”
By measuring the particles to which the top quark decays, scientists capture a measure of the top quark, Liu explained.
But study of the top is still an exotic field, Kehoe said. “For years top quarks were treated as a construct and not a real thing. Now they are real and still fairly new — and it's really important we understand their properties fully.” — Margaret Allen.
