Our current understanding of the Universe suggests that it is composed of an invisible component called “dark matter”. This mysterious type of matter represents more than 25% of the entire matter and energy of which the Universe is made. The matter that we are used to “seeing” in our everyday life and that represents the building blocks for both our bodies and stars that shine in the sky, represents only 5% of the Universe.
How often is cancer transmitted between animals? In the past few years researchers have discovered more transmissible cancers in nature. Initially thought to be contained within a respective host species, new research shows that sometimes even cross-species cancer transmission can occur. With transmissible cancer, instead of remaining in the singular organism or host, the cancer transfers between animals.
Settlers in North America during the 1600s and 1700s grew and raised all their own food, with tiny exceptions, such as importing tea. In the nineteenth century, well over 80 percent of the American public either lived at one time on a farm or made their living farming. Today, just over 1 percent does that in the United States, even though there is a surge going on in small organic family farming.
Like all biological traits, human memory reflects a long evolutionary history, most of it shared with other animals. Yet, with rare exceptions, evolution has either been overlooked in discussions of memory or treated in an outdated way. As a result, a simple idea about the cerebral cortex has reigned for more than a century: that its various areas specialize in functions characterized as memory, perception, the control of movement, or executive control (mainly decision-making).
Climate change governance dramatically challenges traditional International Relations (IR) notions of decision-making. The greatest challenge involves understanding the many ‘actors and the arrangements’ that describe this critical global governance issue. The field is made up of much more than the traditional intergovernmental and international organizations and their actions in a critical global issue.
The story of New York’s red honey struck a chord with those already concerned about honey bee health. Bees have been hit hard by a host of challenges ranging from parasitic mites to neonicotenoid pesticides—but could red honey be another sign of bee decline? Could artificial flavors and chemicals in human foods be toxic to bees? Could we be at risk if we eat “local honey”?
World Space Week has been celebrated for the last 17 years, with events taking place all over the world, making it one of the biggest public events in the world. Highlighting the research conducted and achievements reached, milestones are celebrated in this week. The focus isn’t solely on finding the ‘Final Frontier’ but also on how the research conducted can be used to help humans living on Earth.
As part of Peer Review Week, running from 19-25 September 2016, we are celebrating the essential role that peer review plays in maintaining scientific quality. We asked some of our journal’s editorial teams to tell us why peer review is so important to them and their journals.
Can Peer Review ever be as important as publication? This year’s Peer Review Week focuses on the recognition of reviewers. Peer Review Week 2016 is an international initiative that celebrates the essential and often undervalued activity of academic peer review.
I joined the staff in the Smithsonian’s Department of Entomology, National Museum of Natural History in 1992, at the time Pam Henson and I published “Digging for Dyar: The Man Behind the Myth”. Having stayed in Washington, DC long enough to complete the article, my job at the Museum would give me roughly a dozen years to accumulate information on Dyar, while performing other duties.
This year, Americans celebrate the centennial of the National Park Service. On August 25, 1916, President Woodrow Wilson signed the National Park Service Organic Act. The bill culminated decades of effort by a remarkable generation of dedicated men and women who fought to protect the nation’s natural wonders for the democratic enjoyment of the people.
I first became acquainted with Dyar’s work on the moth family Limacodidae, my chosen entomology dissertation topic, in 1983 at the University of Minnesota. It was in the Hodson Hall library on the St. Paul campus where I noted how Dyar’s authorship dominated the Journal of the New York Entomological Society in the middle to late 1890s. Particularly notable was his running series from 1895-1899
We’re told that we can insert a gene to confer sterility and this trait would race like wildfire through Aedes aegypti. Why this species? Because it’s the vector of the Zika virus—along with the dengue and yellow fever viruses. The problem is that A. aegypti isn’t the only culprit. It’s just one of a dozen or more bloodsuckers that will also have to be wiped out. After we’ve driven these species to extinction, we’ll presumably move on to the Anopheles species that transmit malaria.
Birds do it. Bees do it. Microbes do it, and people do it. Throughout nature, organisms cooperate. Humans are undeniably attracted by the idea of cooperation. For thousands of years, we have been seeking explanations for its occurrence in other organisms, often imposing our own motivations and ethics in an effort to explain what we see.
Cats are among some of the most popular pets in the world, and they’ve been so for thousands of years. In fact, there are more than two million cat videos on YouTube. In appreciation of our feline friends for World Cat Day on 8 August, we’ve put together a list of 12 little-known cat facts.
As my family gazed down on the stratified color bands of geological history in the Grand Canyon, snow and ice lined each ridge, and made each step on the path going down a dangerous adventure, highlighting the glorious drama of the miles-deep gorge. It was dizzying and frightening and awe-inspiring.
