In the late winter of 1976, the world famous fossil collector James Kitching was doing a survey near South Africa’s border with Lesotho.

To his surprise he found a tiny clutch of six fossilized eggs along the side of the road at a place known as Rooidraai.

It took five years for skilled palentologists to remove enough rock matrix from the eggs so that they could be preliminarily identified as the first dinosaur embryos from South Africa and the oldest dinosaur embryos in the world.

You no longer have to look to science fiction to find the cyborg. We are all cyborgs now. Mobile phones, activity trackers, pacemakers, breast implants and even aspirins all act as biological, cognitive or social extensions and enhancements of our bodies and minds. Some have even predicted that human beings as we know them will be replaced by technically enhanced, god-like immortal beings within 200 years. Or at least rich people will.

A company in the Netherlands is building a bridge across a canal in Amsterdam using 3D-printing robots.

It seems that such attention-grabbing headlines appear regularly to declare how 3D-printing is destined to revolutionize manufacturing of all kinds. If the idea that key manufacturing products such as cars, aircraft – or indeed bridges – built by 3D printing sounds like hype, you’re mistaken.

The sex lives of older people have received a lot of attention recently. From the Netflix sitcom Grace and Frankie, which stars Jane Fonda and Lily Tomlin (both in their 70s) and does not shy away from the issue of sex, to the Channel 4 series that focused on “love and sex when we’re over 60”, it seems there is no escaping the message that older adults have and enjoy sex.

Every president for more than 30 years has required executive branch agencies to analyze regulatory impacts before issuing new requirements.

They’ve relied on the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget to review significant new rules to ensure the quality of such regulatory analysis.

The recent commitments by the leaders of G7 nations to reduce emissions of carbon dioxide to 40-70% below current levels by 2050, and to eliminate the use of fossil fuels altogether by 2100, have raised several questions.

Are these objectives feasible? Are they consistent with national commitments? Are they sufficient to stabilize the global climate without dangerous rates of warming? And are they anything new?
