Discoveries in amber, ebikes buyer's guide, and how genes define us. [more]

02/04/2016: Amber: world market and discoveries in amber
The world market for the precious gemstone amber is booming; driven by demand from China, prices have risen by up to 1000% over the past 5 years. Amidst fears that this demand might be slowing, Alex Duval Smith has been measuring the mood at Amberif, the world's annual amber trade fair in Poland. Also, discoveries in amber, and the precious gemstone has proved the perfect storage medium for all kinds of ancient life. George Poinar of Oregon State University has been studying amber and what is in it for over 50 years. It was his pioneering work extracting DNA from insects fossilized in amber that inspired Michael Crichton to write Jurassic Park, the book that gave birth to the massive movie franchise! His discoveries in amber have included 120 million year old weevils, a new plant species that's a 45-million-year-old relative of coffee, ancient flowers, and fossil records of the world's oldest bee.

Fertility apps, Panama Papers, video editing apps, and the microbiome's link to brain health. [more]

09/04/2016: Fertility apps
The self tracking movement uses technology to measure your body and how it is performing. Until now this has tended to focus on your activity levels; how many steps you've made, how far you've run or biked, calories burned versus calories consumed, and your heart rate and blood pressure too. But a woman's menstrual cycle, and how this can be tracked by technology to maximise a woman's fertility, has been a largely neglected area. That's changing fast though, and Moira Weigel has been looking at the latest fertility apps on the market. [more]

09/04/2016: Tech: Panama Papers and video editing apps
Peter Griffin with the technological challenges raised and overcome by this week's revelations surrounding the Panama Papers, a huge collection of millions of documents leaked to a German newspaper and subsequently pored over by hundreds of journalists collaborating all over the world. So how did they manage to do it and keep a lid on their investigations so successfully? Also Peter's been having a play with the latest video editing apps. Rather than having hours of unedited videos sitting on your PC, unwatched and unloved, could you easily turn these into shareable memories of weddings, birthdays, and holidays? [more]

09/04/2016: Your microbiome and brain health
It seems like the colony of bacteria living inside our gut has never been so important! Previous studies have revealed links between the composition of this microbiome and our mood, how likely mothers are to have a preterm birth, whether you own a pet, even how hungover you're going to feel after you've been drinking too much. Now a new study shows the vital role our gut bacteria could be playing in our brain health too. Professor John Cryan and his team at the University College Cork discovered how the colony of bacteria living inside us could be regulating levels of myelin in the brain. Myelin's a fatty white substance that covers many nerve cells like insulating tape, and increases the speed at which signals from our brain can travel about. It could give us some important pointers for the management and even the treatment of conditions like multiple sclerosis, stroke and spinal cord injuries. [more]

Could many operations and surgical procedures employed in hospitals today be working as a powerful placebo? Professor Ian Harris is an orthopaedic surgeon based in Sydney and in his book 'Surgery, the Ultimate Placebo' (NewSouth Publishing) he argues that many times we go under the knife, the operation is useless and can even be harmful. [more]

09/04/2016: Mammograms as cardiac screening tool
Could mammograms be used for more than assessing a woman's risk of breast cancer? Like whether she has heart disease, a condition that in the US is about 7 times more likely to kill her than breast cancer. That's the key finding of a paper published by a team of researchers including Laurie Margolies of the Icahn School of Medicine at Mount Sinai Hospital in New York. She says that for little extra cost or effort a mammogram can become an effective tool to measure a woman's cardiac health. [more]

16/04/2016: Open source lab equipment
Specialist laboratory equipment costs an absolute fortune. The market's small and the markup's big, and a large portion of research money ends up getting swallowed buying kit. That's why an increasing number of scientists are sharing technical plans and using 3D printing technology to make the parts and build the lab equipment they need at a fraction of the cost. Joshua Pearce is an engineer at Michigan Technological University who's written a guidebook for scientists on how to create a low-cost lab. [more]
