If you search Wikipedia for present day habitats on Mars, then you will find many articles about Mars colonization, but on the idea that there might be microhabitats for present day life there, you'll find almost nothing. You'll find my Present day Mars habitability analogue environments on Earth but nothing about the possible habitats they are analogues of. So why is this? Well there was an article on this until just a week or two ago, but it is now deleted.

On September 4 to 8 the city of Mantova, in northern Italy, will be brimming with writers and readers. The event is called "Festivaletteratura" and brings together authors and consumers of books of all kinds, in a week-long kermesse with interviews, debates, public lectures, and the like. 
The Bahama Nuthatch, native to a small area of native pine forest on the island of Grand Bahama, was feared extinct after Hurricane Matthew in 2016, but researchers are pleased to announce that the little-known bird is still out there.

But there may be only two left, they worry.

The Bahama Nuthatch has a long bill, a distinctive high-pitched squeaky call, and nests only in the mature pine trees of the Caribbean island. There may have been a sharp decline in its estimated population, from a believed 1,800 reported in a survey in 2004 to just 23 being seen in a survey in 2007, but it is hard to be sure.

In the 1800s, critics of evolution insisted there had to be fossil evidence for everything, which neglected the idea that fossilization is already difficult, finding the fossil is even more difficult, and something like an eye will not fossilize at all.

But detractors who insisted they would not accept evolution until they found a "missing link" between modern humans and ancestral primates would be moving the goalposts once again, because a fossil of an ancient hominin individual from Siberia had a Neanderthal mother and a Denisovan father. 
Ray tracing has been a hot topic since...well, at least 350 B.C. in the western world, when Aristotle described his camera obscura and wrote that the eye is 'a darkened chamber awaiting light.' Da Vinci was fascinated by it, as was Descartes. And of course Einstein wanted to understand light quanta.

In the 1990s, software and hardware companies began to tout it, but like Atari Jaguar's claim it was a 64-bit machine because it had two 32-bit processors, it was a lot of marketing.
Version 2 of a thick textbook on particle and astroparticle physics is out, and you should have a look at it (well, at least if you're seriously interested in the topic!). The book, titled "Introduction to Particle and Astroparticle Physics" (not a very imaginative title, admittedly, but at least a faithful one) has a more descriptive subtitle: "Multimessenger Astronomy and its Particle Physics Foundations". It is authored by Alessandro de Angelis and Mario Pimenta, two acknowledged experts of the field. 

At the time of writing, 436 people have died following an earthquake in the Indonesian island of Lombok. A further 2,500 people have been hospitalized with serious injuries and over 270,000 people have been displaced.

As lifestyles in the UK have become more stressful and pressurized, people have started to look at alternative ways to live. Some are now seeking out more of a community feel to their home lives, exploring the option of joining an “intentional community”.

Next month, a Microsoft developer, a classical pianist, and a philanthropist for kids' health will compete in the Miss America pageant. And they are all the same person: Allison Farris.

Farris creates and codes apps for Microsoft as a career but next month she is poised to do something with a different kind of elegance. She will represent Washington, D.C. at the Miss America competition on Sept 9, 2018 in Atlantic City, New Jersey, which will be televised on ABC.
A technique used to produce stone tools that were first found 500,000 years ago is likely to have needed a modern human-like hand, according to new research.

The technique is called 'platform preparation' - preparing a striking area on a tool to remove specific stone flakes and shape the tool into a pre-conceived design - and without the ability to perform highly forceful precision grips, our ancestors would not have been able to produce advanced types of stone tool like spear points. 

Platform preparation is essential for making many different types of advanced prehistoric stone tool, with the earliest known occurrence observed at the 500,000-year-old site of Boxgrove in West Sussex, UK.
