Space may be the final frontier, but it’s not beyond the reach of today’s biologists. Scientists in all areas of biology, from tissue engineering to infectious diseases, have been using the extreme environment of space to investigate phenomena not seen on Earth. The National Aeronautics and Space Administration (NASA) has conducted research in the life sciences for almost 50 years.
It is a widely held perception that the United States and United Kingdom, leading nations in the field of science, synergistically combine scientific excellence with ready entry into international networks of scientific collaboration. However, both nations experienced important changes in 2016: the United Kingdom voted to separate from the European Union and the United States elected a controversial president.
Every country that is on the ascendant feels the need for a “coming out” party. In the last half century, that need has been met most often by hosting the Olympic Games. Japan did it in 1964, South Korea followed in 1988, and China in 2008. The Olympic itch seems to come in the wake of economic growth that takes per capita income to the vicinity of $6,000
While it is believed that about one in 50 Americans harbor a brain aneurysm, most will never know it, and their aneurysm will never cause a problem. But rarely, the arterial wall of an aneurysm can become so thin that it bursts, spilling blood over the brain’s surface. This is the most feared outcome of a brain aneurysm and is what drives the urgency in treating many brain aneurysms, even if found accidentally.
When we interact with our world – regardless if by means of a simple grasp, a smile, or the utterance of a sentence – we are typically quite confident that it was us, who intended to and thus executed the interaction. But what is this “us”? Is it something physical or something mental? Is it merely a deterministic program or is there more to it? And how does it develop, that is, how does the mind come into being?
The eleventh of January marks the 130th anniversary of the birth of conservationist, ecologist, and writer Aldo Leopold. As one of Leopold’s biographers, I have become accustomed over the years to marking these milepost dates. They tend to bring forth a strong pulse of articles, commentaries, and editorials. Some are celebratory, perhaps built around a choice bit of Leopold prose
Donald Trump has always had a rocky relationship with the truth. The fact that his pronouncements often fail to align with reality has now simply become an accepted fact. In earlier times candidates who spoke this way would have quickly fallen off the map. Why not Trump? One interesting take on this is the claim that his statements should not be taken literally. What exactly does it mean to not take something literally?
An international team of astronomers led by Professor Simon Jeffery at the Armagh Observatory in Northern Ireland has discovered a small, very blue helium-rich, and hot star called UVO 0825+15, which has a surface extremely rich in lead and other heavy metals and varies in brightness by up to 1% every eleven hours. Only the fourth “heavy-metal subdwarf” discovered, and the second to be variable, the new star raises major questions about how these stars form and work.
Celebrated for his co-discovery of the principle of natural selection and other major contributions to evolutionary biology, Alfred Russel Wallace (1823-1913) also wrote widely on the social, political, and environmental aspects of scientific and technological advance. These latter, if far less familiar, ideas constitute an astute critique of the Victorian concept of progress.
The arrival and dramatic spread of the Zika virus in Brazil and other Latin American and Caribbean countries alarmed public health authorities and the scientific community. This prompted the World Health Organisation (WHO) to declare ZIKV a Public Health Emergency of International Concern on 1 February 2016. In response to this emergency, research on ZIKV was intensified, and within a few months, large amounts of data and outstanding results have been produced.
Alcohol and drug abuse costs Americans approximately $428 billion annually. Despite this enormous cost—which, we must remember, is just the economic face of a community, family, and individually life-shattering problem—the vast majority of those with an alcohol or substance use problem do not receive treatment, and even fewer are likely to achieve long-term sobriety.
Amy Griffin, associate head coach of women’s soccer at the University of Washington in Seattle, first began to wonder about artificial turf and cancer in 2009. “We had two goalies from the neighborhood, and they had grown up and gone to college,” Griffin said. “And then they both came down with lymphoma. “And we were all sitting there chatting—both of them were bald—and they were like, ‘Why us?’
Over the course of the last year, we have witnessed expressions of anger, fear, pitilessness and even hatred both predictably and unexpectedly. The British vote to leave the EU and US voters’ preference for a Trump presidency were prompted in part by feelings of anger towards leaders or ‘the system’ and fear about immigration and identity. The world has watched the war in Syria as thousands die and millions are misplaced with both horror and helplessness.
The recent confirmation that Zika virus is spreading in the southern states of the United States has been met with considerable public anxiety. Infectious diseases strike a particular primal fear in populations, not least because they are perceived to be unfamiliar, strike suddenly and unpredictably, and have strong cultural associations with filth, contagion, or nuisance vectors such as mosquitoes.
With rising health care expenses, we are all trying to solve the paradoxical dilemma of finding ways to develop better, more comprehensive health care systems at an affordable cost. To be successful, we need to tackle one of the most expensive health problems we face, alcohol and drug abuse, which costs us approximately $428 billion annually. Comparatively, the expenses of health care services, medications, and lost productivity for heart disease costs $316 billion per year.
Many clinical decisions are based on laboratory test results. The rapidly expanding number and complexity of these tests present physicians with many challenges in accurately and efficiently ordering and interpreting diagnostic tests. Diagnostic errors affect 5% of US adults who seek outpatient care each year, and contribute to approximately 10% of patient deaths and 6 to 17% of hospital adverse events.
