True And False Discoveries: How To Tell Them Apart

Many new particles and other new physics signals claimed in the last twenty years were later proven to be spurious effects, due to background fluctuations or unknown sources of systematic error. The list is long, unfortunately- and longer than the list of ...

Casimir Effect And Boosting The Force Of Empty Space

A vacuum- empty space- is not as empty as one might think. In fact, empty space is a bubbling soup of various virtual particles popping in and out of existence – a phenomenon called "vacuum fluctuations". Usually, such extremely short-lived part ...

BICEP2 Data, CMB B-modes, Inflation, Alternative Cosmologies... (II)

It is now generally admitted that the BICEP2 Collaboration has not yet produced an evidence for the existence of primordial B-modes in the measured polarization of the cosmic microwave background (CMB) radiation. Contrary to the claim contained in the ini ...

Hybrid Nanowires And A Crystal Wedding In The Nanocosmos

Researchers have succeeded in embedding nearly perfect semiconductor crystals into a silicon nanowire. They say the new method of producing hybrid nanowires, very fast and multi-functional processing units, can be accommodated on a single chip in the futu ...

100,000 Amps: New Magnets Boost Fusion Energy

Assembling yttrium-based high-temperature superconducting tapes in order to fabricate a large-scale magnet conductor has led to the National Institute for Fusion Science (NIFS) in Japan  achieving an electrical current of 100,000 amperes, by far the highe ...

Rotational Wavepackets And Liquid-Like Motion Of Atoms Within An Ultra-Cold Cluster

A new study has unlocked the potential to create new materials using nanosized ‘building blocks’, by using a laser technique to examine in rich detail the structure and internal atomic motion of a small cluster containing an acetylene molecule and a single ...

More On The Alleged WW Excess From The LHC

This is just a short update on the saga of the anomalous excess of W-boson-pair production that the ATLAS and CMS collaborations have reported in their 7-TeV and 8-TeV proton-proton collision data. A small bit of information which I was unaware of, and wh ...

Publishing in scientific journals cost MONEY!? A kickstarter project.

If someone can use Kickstarter to raise $50,000 for making potato salad, perhaps, I can raise at least $2500 to pay publication fees on three papers.   It is a little known fact that formally publishing an article in a scientific journal cost money. ...
