What has functional brain imaging discovered?

By Richard Passingham

Functional magnetic brain imaging (fMRI) is a method that allows us to study the workings of the human brain while people perceive, reason and make decisions. The principle on which it is based is that, when nerve cells or neurons in a particular region become active, there is an increase in the blood supply to that brain area. This can be visualized because the scanner can be sensitized to the changes in the blood oxygen level that occur when the nerve cells become active.

Social work and suicide prevention, intervention, and postvention

By Myfanwy Maple and Rebecca L. Sanford

Social workers regularly come into contact with those who are at risk of or exposed to suicide, through direct practice, as well as in family, group, and community roles. However, social work authors have been notably missing in the scholarly literature on suicide .

Misinterpretation and misuse of P values

By Beatrice Grabowski

In 2011, the US Supreme Court unanimously ruled in Matrixx Initiatives Inc. v. Siracusano that investors could sue a drug company for failing to report adverse drug effects—even though they were not statistically significant. Describing the case in the Wall Street Journal, Carl Bialik wrote, “A group of mathematicians has been trying for years to have a core statistical concept debunked.

The NHS and the Church of England

By Douglas J. Davies

Politicians are more than anxious over negative public opinion on the National Health Service, falling over backwards to say that the NHS is “safe in our hands.” Meanwhile, the Church of England is concerned about losing “market-share,” especially over conducting funerals. One way of linking these two extremely large British institutions is in terms of life-style choices.

Hypnosis and the conscious awareness of intentions

By Peter Lush and Zoltan Dienes

A hypnotist tells a subject that their outstretched arm will begin to rise upward as though tied to an invisible balloon. To their astonishment, the subject’s arm rises just as suggested, and seemingly without their intention. While it may appear as though the subject is being controlled by the hypnotist, it is well established that nobody can be hypnotised against their will. Hypnosis therefore seems to present a paradox

Alcohol and tailgating at football games

By Matthew D. Krasowski

Tailgating is a very popular activity associated with American college football games. Tailgating typically involves food and alcoholic beverages served from the backs of parked vehicles or associated equipment at or near athletic events. At large universities with Division I football programs, the football stadiums may hold upwards of 100,000 fans, sometimes with thousands of additional fans

A new (musical) direction for healthcare?

By Kimberly Sena Moore

Most would agree with the idea that music can have a powerful hold over us—our thoughts, feelings, and movements. Given this, how might music help measure thoughts, feelings, and movements in a way that allows professionals in healthcare improve client treatment? The music therapy profession seems to be experiencing a surge in developing data-measuring tools that incorporate music in the client assessment.

Obstacles in transgender healthcare

By Matthew D. Krasowski and Katie L. Imborek

The last several years have seen increased visibility of transgender individuals in the media in United States. While this has served to increase attention on some issues related to the transgender population, what often gets overlooked is that the transgender population remains one of the most underserved groups in the country.

Can we encourage healthier choices by the way we display food options?

By Marisabel Romero Dipayan Biswas

The results of our recent experiments show that displaying healthy food to the left of an unhealthy option can influence the selection and consumption volume of the healthier choice. Since managers typically have considerable flexibility in terms of how they display food items in retail outlets and restaurant menus, they can use the findings of our research to design optimal menu formats to suit their sales objectives.

Around the world in 15 travel health tips

By Silvia Dell'Amore

It’s time for holidays! Your suitcase is packed, you’re ready to leave, and cannot wait to get a proper tan to show on social media. Mark Twain used to say that “travel is fatal to prejudice, bigotry, and narrow-mindedness”, but unfortunately the health problems we may come across while travelling are far less poetic. Danger is always lurking, especially in far-flung and unexplored destinations.

Years of education may protect against dementia

By Francisca S. Then

Attaining a higher level of education is considered to be important in order to keep up good cognitive functioning in old age. Moreover, higher education also seems to decrease the risk to develop dementia. This is of high relevance in so far that dementia is a terminal disease characterized by a long degenerative progression with severe impairments in daily functioning. Despite a great amount of research emphasizing the relevance of education…

Designer nature: mosquitoes first and then what?

By Jeffrey A. Lockwood

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.

2016: the year of Zika

By Abelardo Q. C. Araujo, Marcus Tulius T. Silva, and Alexandra P. Q. C. Araujo

Zika virus (ZIKV), an arbovirus transmitted by mosquitoes of the Aedes genus, was first isolated in 1947 in the Zika forest of Uganda from a sentinel monkey. It has always been considered a minor pathogen. From its discovery until 2007 only 14 sporadic cases – all from Africa and Southeast Asia – had been detected. In 2007, however, a major outbreak occurred in Yap Island, Micronesia, with 73% of residents being infected.

Bloody Olympics: Rio, 2016, and the history of illegal blood doping

By Chris Cooper

Sport has long had a fascination with blood. The blood of the Roman gladiators, mopped by a sponge from the arena, fed a profitable business; perhaps the athlete’s ultimate commitment to promoting their brand? Today blood is even more relevant to sport.

Olympian pressure

By Alan Currie

Recent years have brought recognition that sportsmen and women may have mental health needs that are just as important as their ‘physical’ health – and that may need to be addressed. Athletes are people too, subject to many of the same vulnerabilities as the rest of us. In addition to our everyday anxieties, the sports world contains a whole host of different stressors.

Mental health inequalities among gay and bisexual men

By Ford Hickson

Depression, substance abuse, and suicide have long been associated with homosexuality. In the decades preceding the gay liberation movement, the most common explanation for this association was that homosexuality itself is a mental illness. Much of the work of gay liberation consisted of dismantling the pathological understanding of homosexuality among mental health professionals.
