Nog nooit was het zo warm in het Midden-Oosten en Rusland, nog nooit was het in Californië zo koud in juli, een vreemde zomerse sneeuwstorm in Alberta en extreme overstromingen in het zuiden van China. Dit zijn slechts een paar voorbeelden van het extreme weer. Het meest opvallende dit jaar is de hitte. Afgelopen juni werd het Midden-Oosten overvallen door een hittegolf die zorgde voor records in vijf verschillende landen. In de periode tussen 14 en 22 juni werden er in Saudi-Arabië, Irak, Koeweit, Tsjaad en Niger nog nooit zulke hoge temperaturen vastgesteld. Op 11 juli werd een record gezet in Rusland toen het kwik steeg naar 44 graden Celsius in Yashkul. Hiermee werd het oude record van 43,7 graden Celsius verbroken, wat stamt uit 1940. Ook het westen van Europa is in de ban van de hitte.

US scientists have introduced a concept design of the "Cornucopia" or Digital Fabricator, a "personal food factory" able to print food from specified ingredients, with no waste at the point of cooking.

More than 100 planets that are a similar size to Earth have been discovered in just the past few weeks, it has been announced. The discovery was made by the space telescope Kepler which has been scanning the skies for planets that are orbiting stars since it was launched in January last year. The breakthrough raises the tantalising prospect that we may not be alone in the Universe. Scientists now believe that there are likely to be around 100 million planets in the Milky Way that harbour exactly the right conditions for life. And they expect to be able to identify around 60 of these habitable Earth-like planets within the next two years.

Boeing unveiled its plans for a capsule spacecraft for ferrying astronauts and cargo to space stations at the biennial Farnborough International Air Show in the UK on July 19th. The craft is designed to fill the gap that will be left when the NASA space shuttles are retired from service next year.

The possibility of going back in time only to kill your ancestors and prevent your own birth has posed a serious problem for potential time travelers, not even considering the technical details of building a time machine. But a new theory proposed by physicists at MIT suggests that this grandfather paradox could be avoided by using quantum teleportation and "post-selecting" what a time traveler could and could not do. So while murdering one’s relatives is unfortunately possible in the present time, such actions would be strictly forbidden if you were to try them during a trip to the past.

The Big Bang theory has formed the basis of our understanding of the universe's origins since it was first proposed in 1927 by Georges Lemaitre. And for good reason: the theory is supported by scientists' latest observations and experiments, and is based on Einstein's widely accepted theory of general relativity. But scientists are always on the lookout for any evidence that might suggest an alternative to the Big Bang. The latest in this area of research comes from astrophysicists Maximo Banados and Pedro Ferreira, who have resurrected a theory of gravity from the early 20th century and discovered that a modified version of the theory may hold some surprises.

In the summer of 2002, a week of heavy rains in Central Texas caused Canyon Lake -- the reservoir of the Canyon Dam -- to flood over its spillway and down the Guadalupe River Valley in a planned diversion to save the dam from catastrophic failure. The flood, which continued for six weeks, stripped the valley of mesquite, oak trees, and soil; destroyed a bridge; and plucked meter-wide boulders from the ground. And, in a remarkable demonstration of the power of raging waters, the flood excavated a 2.2-kilometer-long, 7-meter-deep canyon in the bedrock.

A team of scientists from the Instituto Astrofísica de Canarias (IAC) and the University of Texas has succeeded in identifying one of the most complex organic molecules yet found in the material between the stars, the so-called interstellar medium. The discovery of anthracene could help resolve a decades-old astrophysical mystery concerning the production of organic molecules in space. The researchers report their findings in the journal Monthly Notices of the Royal Astronomical Society.

Many animals possess some kind of magnetic sense, allowing them to navigate by using a magnetic field. The ability to detect a magnetic field, called magnetoreception, has been observed in a variety of animals, including birds, turtles, sharks, lobsters, cows, fungi, and bacteria. However, scientists do not fully understand the mechanisms responsible for this ability. In a new study, physicists have investigated the role of quantum interactions in magnetoreception, and have shown that quantum technologies could be used to enhance or reduce the performance of an animal’s chemical compass, and potentially control other biological functions.

Scientists have made a breakthrough toward creating nanocircuitry on graphene, widely regarded as the most promising candidate to replace silicon as the building block of transistors. They have devised a simple and quick one-step process for creating nanowires, tuning the electronic properties of reduced graphene oxide and thereby allowing it to switch from being an insulating material to a conducting material.

The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approx. 4,537 million years ago. But new research from the Niels Bohr Institute shows that the Earth and Moon must have formed much later - perhaps up to 150 million years after the formation of the solar system.
