Severe defects in mitochondrial function affect at least one in every 5000 births, but mitochondrial disorders can reveal themselves at any age through a wide range of symptoms and as contributing factors to conditions as disparate as diabetes and Parkinson’s disease.

NEUROPSY
Leading scholars argue for the abandonment of a flawed concept.
THE FIT
Is high intensity interval training the latest exercise fad or is there a physiological basis to it?
QUANDARY
The Ebola outbreak has revealed a number of ethical issues that need to be sorted urgently.
OUT OF THIS WORLD
Astronomers search for alien air pollution, and Earth-based lasers could zap space junk.

Which vitamins are backed by scientific evidence and which don’t live up to the hype?
conSCIENCE
Carbon capture and storage is a necessary component of any realistic effort to control global warming.
SIMON SAYS
The main critic of the view that a now-extinct human species inhabited the island of Flores has a good record for media coverage but not so good for scientific judgements that bear scrutiny.
LOWE TECH
The Victorian state election will feature a new party opposed to smart electricity meters on health grounds, while others are campaigning against wifi in schools.
THE NAKED SKEPTIC
While corporations can no longer sue for defamation, they can instead attack skeptics by arguing for intellectual property infringement or practices that damage their business.
THE FOSSIL FILE
A synchrotron scan of a 400 million-year-old fish has revealed how far back our own facial structures evolved, and a 28 million-year-old toothed whale fossil has revealed the origins of echolocation in modern whales.
ECO LOGIC
There is no “silver bullet” solution to declining koala numbers. Successful koala recovery is likely to require very different recovery strategies in different places.
DIRECTIONS
We need to measure industry engagement as well as publications.
EXPERT OPINION
Screening for prostate cancer could reduce deaths from the disease by about one-fifth, according to long-term results of a European study involving over 162,000 men. Despite this new evidence for the efficacy of prostate-specific antigen (PSA) testing, the authors question whether the benefits of screening outweigh the harms, and recommend against routine PSA screening programs.
UP CLOSE PODCAST
