Large Hadron Collider discovers new particle – the pentaquark –
A new kind of particle, called the pentaquark, was discovered by scientists at the Large Hadron Collider yesterday [July 13, 2015]. Physicists had theorised the existence of the pentaquark since the 1960s, but had never been able to prove it until its detection by the world’s most powerful particle smasher at Cern. The discovery of the pentaquark comes after the LHC was used in 2012 to prove the existence of another particle, the Higgs Boson, which confers mass. Large Hadron Collider spokesman Guy Wilkinson said the pentaquark represented a way to combine quarks – the sub-atomic particles that make up protons and neutrons. [Daily Telegraph]

Deal Reached on Iran Nuclear Program –
Iran and a group of six nations led by the United States reached a historic accord on Tuesday to significantly limit Tehran’s nuclear ability for more than a decade in return for lifting international oil and financial sanctions. The deal culminates 20 months of negotiations on an agreement that President Obama had long sought as the biggest diplomatic achievement of his presidency. Whether it portends a new relationship between the United States and Iran — after decades of coups, hostage-taking, terrorism and sanctions — remains a bigger question. Mr. Obama, in an early morning appearance at the White House that was broadcast live in Iran, began what promised to be an arduous effort to sell the deal to Congress and the American public, saying the agreement is “not built on trust — it is built on verification.” [NY Times]

New Horizons: Spacecraft survives Pluto encounter –
A signal received from the New Horizons spacecraft shows that it survived its historic encounter with Pluto. Data in its first call home since Tuesday’s flyby suggest the spacecraft experienced no upsets as it hurtled past the icy world at 14km/s (31,000mph). The signal came through a giant dish in Madrid, Spain – part of a Nasa network of communications antennas. The message took four hours 25 minutes to traverse 4.7 billion km of space. [BBC]

Raheem Sterling: Manchester City sign Liverpool winger in £49m deal –
Manchester City have signed Liverpool and England forward Raheem Sterling for a fee that could reach £49m. City will pay an initial £44m for the 20-year-old, making him the most expensive English player ever. Sterling had asked to leave Anfield and was the subject of two bids from City in June, both of which were rejected. City boss Manuel Pellegrini described Sterling, who has signed a five-year deal, as “one of the best attacking players in world football”. Sterling, who is only behind Gareth Bale on the list of most expensive British players, will wear the number seven shirt. [BBC] See List of the Day
