Rippling space-time: how to catch Einstein’s gravitational waves

Albert Einstein made an executive decision to revolutionise our understanding of gravity in a paper published in 1916. Nearly 100 years on, a key prediction of Einstein’s theory has eluded direct detection…
The ghost-like image of Tupac captured the imagination of concert-goers … imagine if they’d seen a real hologram.

Beyond Tupac – the future of hologram technology

Last week the world watched on as a supposed hologram of the late rapper Tupac Shakur performed at the Coachella music festival in California. But was it a hologram? The term “hologram”, (“holos” meaning…
Pepper’s Ghost is an amazing technique, but holograms, done right, are so much cooler. kisokiso

Tupac’s rise from the dead was, sadly, not holography

Last week rapper Tupac Shakur performed at the Coachella music festival in California – a notable feat given he was shot dead in 1996. Tupac’s glowing image appeared on stage, rapping, dancing and interacting…

Heat flows at an atomic level

A single layer of atoms can be used to enhance or restrict heat flow between materials. The finding comes as researchers…
The multi-million dollar facility provides cutting-edge tools for scientists. Nancy Mills, Australian Synchrotron.

The Australian Synchrotron is great … but what does it do?

Science is like high-performance racing: today’s Formula One machine is all too soon the jalopy of tomorrow. The Australian Synchrotron, opened in 2007 and located in Melbourne, is currently at the F1…
Iran is constructing nuclear power stations; that much is clear. AAP

Could Iran be building nuclear weapons? A scientific perspective

There is much concern that Iran is in the process of developing nuclear weapons. Such a development, we’re told, could induce Israel to launch a unilateral military strike with all types of unpredictable…

Does antimatter weigh more than matter?

Researchers have developed, for the first time, a method to efficiently produce long-lived “positronium” – a bound state…
Watch your maths: an Australian Academy of Science report looks to be based around mistaken use or interpretation of numbers. Flickr/emdot.

Science not plummeting in schools: report is ‘way out’

The Federal Department of Education says it advised the Australian Academy of Science’s authors of a break in the series…

Light likes passing through blocked holes

Placing a metal cap over a small hole in a metal film does not stop light passing through, but rather enhances its transmission…
Photosynthesis converts low-energy photons into usable energy; it may teach us how to do the same. papalars

New chlorophyll could hold the key to more efficient solar panels

As the great spectre of climate change continues to loom large over the future, the search for viable, renewable energy sources is becoming ever more important. Solar power has long been seen as a vital…

Lithium the key to quicker fusion

Experimental fusion can be made more efficient by coating reactor walls with lithium, scientist have found. The lithium coating…
If the signs are right, fundamental equations of cosmology may need altering. waljoris

Is life on Earth due to a quirk in the laws of physics?

A radical discovery by my colleagues and I – reported this week in Physical Review Letters – could help explain why it was possible for life (at least as we know it) to develop on Earth, but not in other…

Explainer: Einstein’s Theory of General Relativity

It’s the year 2100. You wake up alone in a small, windowless room. The only other thing in the room is a small ball. Maybe the room is located in your city, but maybe it’s inside that new spaceship everyone’s…
