Ice time
On 23 September 1840 the wonderfully eccentric Oxford geologist William Buckland (1784–1856) and the Swiss naturalist Louis Agassiz (1809–1873) left Glasgow by stagecoach on a tour of the Scottish Highlands.
Will caloric restriction help you live longer?
By Dmytro Gospodaryov and Oleh Lushchak
The idea of extending life expectancy by modifying diet originated in the mid-20th century when the effects of caloric restriction were found. It was first demonstrated on rats and then confirmed on other model organisms. Fasting activists like Paul Bragg or Roy Walford attempted to show in practice that caloric restriction also helps to prolong life in humans.
Bumblebees in English gardens
By Michael Hanley
Urban gardens are increasingly recognised for their potential to maintain or even enhance biodiversity. In particular the presence of large densities and varieties of flowering plants is thought to support a number of pollinating insects whose range and abundance has declined as a consequence of agricultural intensification and habitat loss.
An interview with I. Glenn Cohen on law and bioscience
There are huge changes taking place in the world of biosciences, and whether it’s new discoveries in stem cell research, new reproductive technologies, or genetics being used to make predictions about health and behavior, there are legal ramifications for everything. Journal of Law and the Biosciences is a new journal published by Oxford University Press in association Duke University, Harvard University Law School, and Stanford University, focused on the legal implications of the scientific revolutions in the biosciences.
Thinking more about our teeth
Most of us only think about teeth when something’s wrong with them — when they come in crooked, break, or begin to rot. But take a minute to consider your teeth as the extraordinary feat of engineering they are. They concentrate and transmit the forces needed to break food, again and again, up to millions of times over a lifetime. And they do it without themselves being broken in the process — with the very same raw materials used to make the plants and animals being eaten.
Colorful spiders?
By Rainer Foelix
Spiders are not exactly renowned for being colorful animals. Admittedly, most of the more than 40,000 spider species are rather drab looking. However, there are certainly several hundred species which are lively colored, e. g. bright red or bright green, and some are very colorful indeed.
Preparing for ASEH 2014 in San Francisco
By Elyse Turr
San Francisco, here we come. Oxford is excited for the upcoming annual conference of the American Society for Environmental History in San Francisco this week: 12-16 March 2014. The theme of the conference is “Crossing Divides,” reflecting the mixed history of the discipline and California itself.
Neanderthals may have helped East Asians adapting to sunlight
Hominins and their closest living relative, chimpanzees, diverged approximately 6.5 million years ago on the African continent. Fossil evidence suggests hominins have migrated away from Africa at least twice since then. Crania of the first wave of migrants, such as Neanderthals in Europe and Peking Man in East Asia, show distinct morphological features that are different from contemporary humans (also known as Homo sapiens sapiens).
Conservation physiology of plants
By Mark van Kleunen
Conservation physiology was first identified as an emerging discipline in a landmark paper by Wikelski and Cooke, published in Trends in Ecology and Evolution in 2006. They defined it as “the study of physiological responses of organisms to human alteration of the environment that might cause or contribute to population decline”.
Proving Polybius wrong about elephants
By Adam L. Brandt and Alfred L. Roca
Do conservation genetics and ancient Greek history ever cross paths? Recently, a genetic study of a remnant population of elephants in Eritrea has also addressed an ancient mystery surrounding a battle in the Hellenistic world.
Predicting who will publish or perish as career academics
By Bill Laurance, Carolina Useche, Corey Bradshaw, and Susan Laurance
It doesn’t matter whether or not you think it’s fair: if you’re an academic, your publishing record will have a crucial impact on your career. It can profoundly affect your prospects for employment, for winning research grants, for climbing the academic ladder, for having a teaching load that doesn’t absorb all your time, for winning academic prizes and fellowships, and for gaining the respect of your peers.
How we all kill whales
By Michael Moore
My first job after veterinary school in 1983 was for the International Whaling Commission examining the efficacy of explosive harpoons for killing fin whales on an Icelandic whaling vessel. Later, I encountered a very different way of killing whales.
Floods, storms, and climate change: the need for a longer-term perspective
By Robert Van de Noort
The United Kingdom is experiencing a period of extreme rainfall and an onslaught of Atlantic storms. This has resulted in extensive and prolonged flooding of the Somerset Levels and a rise in the levels of the River Thames not seen for over 60 years, flooding many homes for the first time since these were built.
Evolutionary psychology: an affront to feminism?
By Anne Campbell
Getting ready for work the other morning, I was diverted from pouring my coffee by the television news. A comet was about to pass near the sun and might, if it survived, become visible on earth. The professor of astrophysics who had been brought on to explain the details was engaging, enthusiastic and clear. She was a woman. I wondered how many school girls had heard her and been inspired. Fifty years ago, the idea of a woman gaining recognition in such an arcane area of science would have been astounding.
Second childhood
By Jamie Davies
Embryologists who study the beginning of life, and gerontologists who study its end, interact rather little. This is hardly surprising: the former work with growth, construction and preparation for the long life ahead, while the latter work with loss, decline, and the inevitable journey to oblivion.
Celebrating Charles Darwin’s birthday
February 12th has been coined Darwin Day because it marks the anniversary of the birthday of Charles Darwin. One could come up with several creative ways to celebrate the life of such an influential and revered scientist—baking a cake with 73 candles in honor of Darwin’s 73 years of life, or taking a walk through a local park or nature reserve in an attempt to make observations about wild animals, to name a few.
