Earth Day is an annual celebration, championed by the Earth Day Network, which focuses on promoting environmental protection around the world. The Earth Day Network’s mission is to build a healthy, sustainable environment, address climate change, and protect the Earth for future generations. The theme for Earth Day 2016 is Trees for the Earth, raising awareness around protecting the Earth’s forests.
“We may, without knowing it, be writing a new definition of what science is for,” said Aldo Leopold to the Wildlife Society in 1940. A moderate but still crisp April breeze was playing in my hair as the sun worked to melt the last bits of frost in the silt. Shoots of prairie grasses were popping up through the mud, past shell skeletons of river mussels and clams.
How did it come to this? How was evolution transformed from a scientific principle of human-as-animal to a contentious policy battle concerning children’s education? From the mid-19th century to today, evolution has been in a huge tug-of-war as to what it meant and who, politically speaking, got to claim it.
The recent tragedy involving toxic, lead-laced tap water in Flint, Michigan highlights the growing gulf between rich and poor, and majority and minority communities. In an ill-fated measure to save costs for the struggling city of Flint, officials stopped using Detroit’s water supply system and switched to the Flint River.
Many say now is the century of biology, the study of life. Genomics is therefore “front-and-centre”, as DNA, is the software of life. From staring at stars, we are now staring at DNA. We can’t use our eyes, like we do in star gazing, but just as telescopes show us the far reaches of the Universe, DNA sequencing machines are reading out our genomes at an astonishing pace.
Proving to be both varied and fascinating, moons are far more common than planets in our Solar System. Our own Moon has had a profound influence on Earth, not only through tidal effects, but even on the behaviour of some marine animals. But how much do we really know about moons?
These are the images I carry in memory that form my understanding of passion and compassion in science: Rachel Carson waking at midnight to return to the sea the microscopic marine organisms she has been studying, when the tidal cycle is favorable to their survival; John Muir clinging to the upper branches of a tall pine during a violent storm, reveling in the power of natural forces.
When people think of evolution, many reflect on the concept as an operation filled with endless random possibilities–a process that arrives at advantageous traits by chance. But is the course of evolution actually random? In A World from Dust: How the Periodic Table Shaped Life, Ben McFarland argues that an understanding of chemistry can both explain and predict the course of evolution.
Most people living in large towns and cities probably give little thought to soil. Why should they? At a first glance, much of the ground in towns and cities is sealed with concrete, asphalt and bricks, and most city-dwellers have little reason to have contact with soil. To most, soil in cities is simply dirt. But soil is actually in abundance in cities: it lays beneath the many small gardens, flower beds, road and railway verges, parks, sports grounds, school playing fields, and allotments of the city, where it plays many under appreciated roles.
Arachnophobia, an irrational fear of spiders, affects millions of people around the world. This is not helped by popular culture portraying them as scary, deadly creatures who could creep up on you, and bite you, when you least expect it. They also do look pretty creepy… We’ve found the following ten facts about these misunderstood creatures.
In today’s world where the majority of developed countries tend to favor monogamous relationships, what should we think about polygamy? David P. Barash, author of Out of Eden: The Surprising Consequences of Polygamy, reveals a few facts about polygamy that’ll give you some food for thought.
Deception is rife in nature, from spiders that mimic ants for protection through to carnivorous plants that lure insects with attractive smells. As highly visual animals ourselves it’s only natural that we humans often judge the appearance of other species through our own senses.
2016 is a leap year. A leap year, or intercalary year, is a year with an extra day inserted to keep pace with the seasons. In the Gregorian calendar this falls every four years on Feb 29th. On Leap Day this year a wonderful piece of science was published about an equally rare part of nature – giant viruses.
Some individuals loom larger in mycological history than they deserve, but, to be fair, this mild indictment applies both to those with, and those without, a Y chromosome. The science of mycology blossomed in Darwin’s time, when German botanist Anton de Bary (1831-1888) began to decode the life cycles of fungi and penned the first textbook on fungi.
The Paris Agreement, held from 30 November to 12 December 2015, has been hailed as a “historic turning point” in the battle against global climate change. Consequently, dialogue surrounding greenhouse gas emissions, particularly around political and economic compliance.
Amid failures in saving numerous wildlife species worldwide, there is an encouraging success—decades of panda habitat degradation have been transformed into a remarkable recovery. The success is taking place in Wolong Nature Reserve of China—home to endangered giant pandas and more than 5,000 residents who share a 200,000-ha mountainous area. It is also occurring in many of the other 66 nature reserves and non-reserve areas across southwestern China.
