Higgs boson discovery: now the real work begins
Scientists at Cern are confident they have found the 'God particle', but months and years of analysis lie ahead
The search for the arcane, theoretical particle known as the Higgs boson has drawn on the world's largest scientific instruments and occupied thousands of researchers over more than two decades. The discovery – or probable discovery – at Cern, the particle physics lab near Geneva, will go down as a triumph of science, engineering and collective hard graft. Now the real work begins.
Months and years of analysis lie ahead to confirm that the particle is the elusive Higgs boson. If so, physicists want to know whether it is the simplest kind of particle put forward in physicists' theories, or something more unusual – and more exciting.

"Gottesteilchen"? Neues Elementarteilchen entdeckt
Seit 40 Jahren fahnden Physiker nach dem Higgs-Boson, das wegen seiner zentralen Rolle in der Urknalltheorie auch „Gottesteilchen“ genannt wird. Bei der mit Hochspannung erwarteten Pressekonferenz am Kernforschungszentrum CERN ist am Mittwoch ein neues Elementarteilchen präsentiert worden. Nach Ansicht des Forscherteams könnte es sich dabei um das viel gesuchte „Gottesteilchen“ handeln: „Es ist ein vorläufiges, aber ein sehr überzeugendes Ergebnis“, sagte der führende CERN-Wissenschaftler Joe Incandela.

Higgs boson announcement live: Cern scientists discover subatomic particle
12.09pm: Ian Sample has this thought for us:
Stephen Hawking bet Gordy Kane (UMICH) $100 that the Higgs would never be found at Cern. Wonder if he's conceded defeat? #Higgs #ichep2012
— Ian Sample (@iansample) July 4, 2012
12.03pm: The science community seems agreed: this is a big moment. But many, like Heuer, are cautioning that this could be just the beginning.
Dr Roberto Trotta, Lecturer in Cosmology at Imperial College London, has this to say, according to the Science Media Centre.

Higgs boson-like particle discovery claimed at LHC
Cern scientists reporting from the Large Hadron Collider (LHC) have claimed the discovery of a new particle consistent with the Higgs boson.
The particle has been the subject of a 45-year hunt to explain how matter attains its mass.
Both of the Higgs boson-hunting experiments at the LHC see a level of certainty in their data worthy of a "discovery".

God particle is 'found': Scientists at Cern expected to announce on Wednesday Higgs boson particle has been discovered
Scientists at Cern will announce that the elusive Higgs boson 'God Particle' has been found at a press conference next week, it is believed.
Five leading theoretical physicists have been invited to the event on Wednesday - sparking speculation that the particle has been discovered.
Scientists at the Large Hadron Collider are expected to say they are 99.99 per cent certain it has been found - which is known as 'four sigma' level.

Eggs unlimited: an extraordinary tale of scientific discovery
Two biologists, split by rivalry and disagreement, suddenly realised that they were on the same side. The result was a revolutionary breakthrough.
A dogma has haunted the study and treatment of female infertility for more than half a century. It states that a baby girl is born with an ever-diminishing number of egg cells which cannot be renewed or replenished during her life, and that when she runs out of these eggs an irreversible menopause begins.

LHC is back with big energy boost
The Large Hadron Collider (LHC) is operating again after its winter break.
Early on Thursday, opposing stable beams of protons were smashed into each other at four observation positions.
The total collision energy in these bunches of sub-atomic particles was eight trillion electron volts - a world record.

3D-Drucker mit Nano-Präzision
Mikroskopisch kleine Details ausdrucken, in drei Dimensionen – das wird durch die „Zwei-Photonen-Lithographie“ möglich. Diese Technologie kann zum Herstellen von winzigen maßgeschneiderten Strukturen genützt werden. Forschungsteams der TU Wien konnten diese Technologie nun entscheidend verbessern: Der Hochpräzisions-3D-Drucker der TU Wien druckt um Größenordnungen schneller als bisherige Geräte.

A 285 µm racecar - Tiny Nanoscale 3D Printing
In the video, a race car with dimensions of 330x130x100µm3 is fabricated. The structure consists of 100 layers, each made of an average of 200 polymer lines. It is finished in 4 minutes and resembles the CAD file at a precision of ±1µm.

"Überlichtschnelle" Neutrinos wegen fehlerhafter Kabelverbindung?
Anscheinend handelt es sich bei der Entdeckung überlichtschneller Neutrinos um einen Messfehler, verursacht durch das neuartige GPS-System, das die exakte Flugzeit der Neutrinos bestimmt. In einer Stellungnahme sagt die OPERA-Kollaboration, die das ursprüngliche Ergebnis publiziert hatte, dass sie zwei mögliche Fehlerquellen in dem System identifiziert haben. Sie bestätigen damit eine Meldung auf der Webseite von "Science", dass ein Fehler in einer Kabelverbindung gefunden worden sei. Außerdem gebe es ein Problem mit einem Oszillator, der die hochpräzisen Zeitstempel für Neutrinoereignisse produziert. Die Wissenschaftler hatten im September 2011 Messergebnisse öffentlich gemacht, nach denen Neutrinos aus dem Beschleuniger CERN bei Genf 60 Nanosekunden früher in Gran Sasso eintrafen, als sie mit Lichtgeschwindigkeit für die Strecke gebraucht hätten.

Faster Than the Speed of Light?
Some months ago, news broke indicating that scientific measurements in Italy had determined that some neutrinos could travel faster than the speed of light. The media jumped on the hype bandwagon and declared the "death of Einstein's theory of relativity." Physicists (aka, the experts on these questions) were skeptical because ALL previous experimental and observational data, including neutrinos and light traveling from super nova explosions really really far away and reaching Earth at exactly the same time, confirmed Einstein's predictions, so they concluded there must have been some error in the measurement, the analysis, the equipment, etc. on which the Italians relied. Of course, there were also cultural reasons for doubt: as Sergio Bertolucci, research director at CERN indicated, "I have difficulty to believe it, because nothing in Italy arrives ahead of time." :)
