What’s the deal with genetically modified (GM) foods?

By Mary M. Landrigan and Philip J. Landrigan

It’s complicated; but here is a quick summary of what the controversy over genetically modified foods is all about. GM engineering involves reconfiguring the genes in crop plants or adding new genes that have been created in the laboratory. Scientific modification of plants is not something new. Since time began, nature has been modifying plants and animals through natural evolution, meaning that the plants and ani­mals that adapt best to the changing environment survive and pass their genes on to their offspring. Those that are least fit do not survive.

Better health care delivery: doing more with existing resources

By Boaz Ronen, Joseph S. Pliskin, and Shimeon Pass

The healthcare sector faces challenges which are constantly escalating. Populations are growing worldwide and so is the share of the elderly in society. There is a constant proliferation of new medications, diagnostic methods, medical procedures and equipment, and know-how. This huge progress greatly improves the quality of medical treatment but at the same time increases its costs. Governments and authorities are allocating ever growing budgets to healthcare systems but the increased budgets do not cover the increased costs of providing quality healthcare to the public.

Animal of the Month: the lesser known penguins

Penguins have fascinated zoologists, explorers, and the general public for centuries. Their Latin name—Sphenisciformes—is a mixture of Latin and Greek derivatives, meaning ‘small wedge shaped’, after the distinctive form of their flightless wings. The genus of penguins comprises more than just the famous Emperors of the Antarctic, and while public awareness is growing, many of the seventeen extant members of this bird family, their habitats, and threats to their survival, remain relatively unknown.

In defense of beating dead horses: probing a subtle universe

By Steven Vigdor

A February 2017 Workshop on Robustness, Reliability, and Reproducibility in Scientific Research was sponsored by the US National Science Foundation (NSF).  The workshop was part of NSF’s response to growing concerns in Congress triggered by increasing media coverage of an apparent lack of reproducibility among findings, especially in clinical sciences. The participants, spanning diverse scientific subfields, were charged to assess the extent of any problems of reliability and reproducibility, and to formulate next steps toward solutions.

What causes oral cancer and how can we prevent it?

By Hugh Devlin and Rebecca Craven

We know that excessive consumption of alcohol is detrimental to oral health, but why? We know that tobacco smoking, alcohol, and poor oral hygiene cause increased acetaldehyde levels in saliva. Alcohol itself is not carcinogenic, but it is metabolised to acetaldehyde which has been strongly implicated in the development of oral cancer. The variation between people in how they metabolize alcohol might explain why some are at greater risk of cancer than others.

The art of microbiology

By Sarah Adkins, Rachel Rock, and Jeff Morris

Sir Alexander Fleming famously wrote that “one sometimes finds what one is not looking for”. The story of Fleming’s serendipitous discovery of penicillin in the 1920s is familiar to most microbiologists. While the Scottish scientist and his family were on vacation, a fungal contaminant spread across – and subsequently killed – a lawn of bacteria growing on agar plates from one of his experiments.

National Volunteer Month: a reading list

By Deborah Carr

On 20 April 1974, President Richard M. Nixon declared National Volunteer Week, to honor those Americans whose unpaid “efforts most frequently touch the lives of the poor, the young, the aged and the sick, but in the process the lives of all men and women are made richer.” This commemoration has since been extended to a full month to recognize those who offer their time, energy, and skills to their communities.

The four principles of medicine as a human experience

By David Rosen and Uyen B. Hoang

The standard in medicine has historically favoured an illness- and doctor-centered approach. Today, however, we’re seeing a shift from this methodology towards patient-centered care for several reasons. In the edited excerpt below, taken from Patient-Centered Medicine, David H. Rosen and Uyen Hoang explore four core principles that underlie the foundation of this clinical approach.

The return of opiophobia

By Robert C. Macauley

Opiophobia (literally, a fear of opioids or their side effects, especially respiratory suppression) has been around for a long time. Nowadays it’s primarily prompted by the opioid epidemic that has caused a five-fold increase in overdose deaths over the past two decades. With opioids implicated in over 40,000 deaths in the United States each year, interventions such as daily milligram limits, short-term prescribing, and “risk evaluation and mitigation strategies” are important public health measures.

What to do about tinnitus?

By Erin Martz and yahav oron

Tinnitus (i.e., ear or head noises not caused by external sounds) is common among the general population across the world. Tinnitus can be experienced as a “ringing in the ears.” It can also sound like a hissing, sizzling, or roaring noise. It can be rhythmic or pulsating. Tinnitus can be a non-stop, constant sound or an intermittent sound that disappears and returns without a pattern. It can occur in one or both ears.

Modernization of mortuary practice and grief

By Claire White-Kravette

Modern western mortuary practices are characterized by the professionalization of the management and presentation of the corpse. These practices serve as a stark contrast to those in traditional societies across the world and those throughout history. Changes to how we treat and dispose of the dead are such that industrialized societies have become outliers on the spectrum of the world’s cultures.

Conflict-resolution mantras for the workplace and everyday life [infographic]

By Marissa Lynch

Great leaders show composure during stressful situations. But remaining cool and collected in times of crisis is easier said than done, partly due to our own behavioral patterns. Allowing ourselves to become tethered to a particular agenda or resolution puts us at risk for increased stress and diminished communication.

Being open to personal change is the first step to improving conflict-resolution habits. Self-management allows leaders to more effectively manage conflicts. Mantras (or internal chants) are a great way to self-manage: these small reminders can help us control our emotions and, in turn, any conflicts that arise.

Triggered ideas: finding inspiration

By Dawn Field

Where do find your ideas? Are they buried deep in you and suddenly percolate up? Are they glimmers that appear over time until they coalesce into ‘an idea’? Are they reactions to something you see, hear, or do. Likely, you’ve experienced all three and certainly all are the result of accumulated experiences. The last one is special though, in being what we can call ‘triggered’. Something triggered your emotions or imagination and you acted in response.

Artificial intelligence in oncology

By Kiashini Sriharan

There is no denying the presence of computers in our everyday life, whether it’s through phones, personal virtual assistants such as Apple’s Siri and Amazon’s Alexa, or video games. Lately, the interest and development surrounding artificial intelligence (AI) has escalated, and the opportunities to embrace this within the healthcare industry seem to be growing.

What is allowed in outer space?

By Christopher D. Johnson

Humanity is no longer just exploring outer space for the sake of leaving flags and footprints. On February 6, the SpaceX Corporation conducted a successful first flight of its Falcon Heavy rocket, capable of carrying 63,800 kg (140,700 lb) to Low Earth Orbit (LEO), a capability not seen since the Apollo era. As the rocket’s reusable stages can be refueled and reflown, this rocket is a significant innovation and not merely a return to past capabilities.

Collaboration for a cure: harnessing the power of patient data

By Taz Cheema

I am a classic example of a fitness fanatic who uses a wearable device to count my steps, measure my heart rate, and track my sleep pattern. Every day, I am armed with data gathered about my physical activity, alerting me as to whether I’ve been slacking in the gym or eating too many bags of crisps. There is no doubt that now, more than ever, we live in a world where ‘big data’ is ubiquitous in influencing our daily decisions.
