The impact of roads on wildlife (both directly through wildlife-vehicle collisions, and indirectly due to factors such as habitat fragmentation) has likely increased over time due to expansion of the road network and increased use and number of vehicles. In the UK, for example, there were only 4.2 million vehicles on the roads in 1951, compared to 37.3 million by the end of 2016.
The first machine known as the typewriter was patented on 23rd June 1868, by printer and journalist Christopher Latham Sholes of Wisconsin. Though it was not the first personal printing machine attempted—a patent was granted to Englishman Henry Mill in 1714, yet no machine appears to have been built—Sholes’ invention was the first to be practical enough for mass production and use by the general public.
Orangutans quite literally are “persons of the forest,” at least according to their Malay name (orang means “person” and hutan is “forest”). But this is more than just a name. As well as their distinctively “human” qualities, these large charismatic fruit-eaters are also gardeners, forest engineers responsible for spreading and maintaining a wide array of tree species.
What is social entrepreneurship? In essence, it’s about using the tools of entrepreneurship—opportunity, resourcefulness, innovation—to address stubborn social and environmental problems. A defining feature of social entrepreneurship is the concept of systemic change; that is, change that addresses the underlying social, political, and economic forces that conspire to exclude the poor and marginalised from the opportunities that many of us take for granted.
According to the Australian euthanasia activist Philip Nitschke, to choose when you die is “a fundamental human right. It’s not just some medical privilege for the very sick. If you’ve got the precious gift of life, you should be able to give that gift away at the time of your choosing.” This view combines two extreme standpoints in the debate on euthanasia and assisted suicide.
This June, people around the globe are marking World Giraffe Day, an annual event to recognise the bovine dwellers of the African continent. While these long-necked herbivores remain a firm favourite of the safari, there remains much about the giraffe which is relatively unknown. In order to celebrate our Animal of the Month, we bring you 10 amazing facts about the giraffe.
It’s nearly 60 years since C.P. Snow gave his influential “Two Cultures” lecture, in which – among many other significant insights – he advocated that a good education should equip a young person with as deep a knowledge of the Second Law of Thermodynamics as of Shakespeare. A noble objective, but why did Snow highlight this particular scientific law?
On the day after the horrific shooting that claimed the lives of 17 students at Stoneman Douglas High School in Parkland, Florida, the local state representative predicted what would happen next. “Nothing.”
Rarely has a research field in physics gotten such sustained worldwide press coverage as gravity has received recently. A breathtaking sequence of events has kept gravity in the spotlight for months: the first detection(s) of gravitational waves from black-holes; the amazing success of LISA Pathfinder, ESA’s precursor mission to the LISA gravitational wave detector in space; the observation — first by gravitational waves with LIGO and Virgo, and then by all possible telescopes on Earth and in space — of the merger of two neutron stars, an astrophysical event that likely constitutes the cosmic factory of many of the chemical elements we find around us.
This year is the centenary of the Spanish influenza pandemic of 1918. However, it was only by 2010 that the industry had started universal flu vaccine trials, following the Swine flu pandemic in 2009. Explore the last hundred years of flu, as we mark the Spanish flu centenary, from the four major pandemics to the medical advances along the way, with this interactive timeline.
Why should a trained scientist be seriously interested in science past? After all, science looks to the future. Moreover, as Nobel laureate immunologist Sir Peter Medawar once put it: “A great many highly creative scientists…take it for granted, though they are usually too polite or too ashamed to say so, that an interest in the history of science is a sign of failing or unawakened powers.”
Madagascar is famous for the immense diversity of animals that are found nowhere else in the world. Among its most famous animals number the chameleons: both the largest (Parson’s chameleon, Calumma parsonii, or Oustalet’s chameleon, Furcifer oustaleti, depending on how you define “large”) and smallest (the dwarf leaf chameleon, Brookesia micra) chameleons are native to Madagascar. In fact, about half of the over 200 species of chameleons are strictly Malagasy.
In recent years, consumer surveys have shown an upward trend in Father’s Day gift-giving. According to the National Retail Federation, U.S. Father’s Day spending in 2017 hit record highs: reaching an estimated $15.5 billion. This change could be related to nature of modern fatherhood: today’s dads report spending an average of seven hours per week on child care (nearly triple what fathers reported 50 years ago). To celebrate Father’s Day, we put together a video collection of books we think dads will love. More details about each book can be found in the list below. If you have any reading suggestions for Father’s Day, please share in the comments section!
In the twentieth century, 40 to 60 million defenseless people were massacred in episodes of genocide. The 21st century is not faring much better, with mass murder ongoing e.g. in Myanmar and Syria. Many of these cases have been studied well, both in detailed case studies and in comparative perspectives, but studying mass murder is no picnic.
Many individuals in the United States will receive a cancer diagnosis this year. Such a diagnosis is upsetting to those who receive it and overwhelming to those—relatives or friends—who love them. Cancer is rarely experienced in isolation.
Within its first month, the Trump administration revoked federal guidelines designed to promote protections for lesbian, gay, bisexual, transgender, queer or gender non-conforming youth (LGBTQ-GNC) public school students. This move received significant media attention, much of which focused on the challenges of growing up LGBTQ-GNC, and the unique role of schools as places that should be safe and supportive for all students.
