New Scientist - Ma, 16/10/2018 - 17:40
Reports that 2018’s blockbuster video game saw people working 100-hour weeks are troubling, given that tech firms could make workers’ lives easier, says Michael Cook

A coalition of major global figures say we must do much more to adapt to our rapidly warming world, and we need to do it fast

Electric chewing gum zaps your tongue to create a virtual flavour hit

New Scientist - Ma, 16/10/2018 - 08:00
An 'unlimited chewing gum' uses an electric charge to trick you into experiencing flavours – and they don’t fade in the way chewing gum flavour usually does

National bans on smacking children linked to less teenage violence

New Scientist - Ma, 16/10/2018 - 00:30
A survey has found that teenagers get into more fights in countries where it is legal to spank children, but there could be several explanations for the link

Will there be beer shortages as the world warms? Well, maybe

New Scientist - Lu, 15/10/2018 - 17:00
Predictions of beer shortages and rocketing prices as extreme weather hits barley production should not be taken too literally but do highlight a very real problem

New Scientist - Lu, 15/10/2018 - 17:00
Chemical evidence locked in rocks and oil suggests that the first animals were alive 100 million years earlier than we thought from fossils

Brown hares are turning up dead across the UK, raising fears that myxomatosis – the rabbit infection in ‘Watership Down’ - may have mutated to target hares

[Editorial] Stemming the global caesarean section epidemic

The Lancet - Sa, 13/10/2018 - 00:00
The major rise in caesarean sections around the world is called unprecedented and unjustified in a new Lancet Series on optimising caesarean section use published today.

[Editorial] DR Congo: managing Ebola virus in war

The Lancet - Sa, 13/10/2018 - 00:00
The latest Ebola virus outbreak across DR Congo is testing international and local health responses under conditions of extreme stress. The country is deep in a protracted conflict, and efforts to control Ebola virus in the conflict zone are hampered by conditions of war, which have led to a fractured society, a weakened health system, and widespread poverty and hunger. Against this backdrop, WHO's Director-General Dr Tedros Adhanom Ghebreyesus, last week, in his speech at a UN Security Council meeting, raised the risk assessment of regional spread of Ebola virus disease from high to very high, and highlighted concern of spread into Uganda, Rwanda, South Sudan, and Burundi.

[Editorial] Are Brazilian elections healthy without a plan for UHC?

The Lancet - Sa, 13/10/2018 - 00:00
On Oct 7, Brazilians held the first round of voting to elect a new president. With the backdrop of economic and political crisis, the election has been closely contested with a particular focus on crime and corruption. That has left little airtime to debate health-care policy at a precipitous time for the Brazilian National Health System (Sistema Único de Saúde), which faces a number of challenges. Persistent underfunding and weakening exchange rates have led to shortages of basic medicines and hospital beds, as described in a Lancet World Report.

[Editorial] Serão as eleições no Brasil saudáveis, sem um plano para o direito universal à saúde?

The Lancet - Sa, 13/10/2018 - 00:00
No dia 7 de Outubro, os Brasileiros votaram no primeiro turno de eleição para um novo presidente. Num cenário de crise política e econômica, a eleição tem sido uma disputa apertada com um enfoque particular na violência e na corrupção. Assim, o tempo disponível para discussão de políticas de saúde esta muito reduzido, num momento crítico em que o Sistema Único de Saúde do Brasil enfrenta numerosos desafios. O subfinanciamento persistente, e a desvalorização da taxa de câmbio deram origem à falta de medicamentos básicos e falta de leitos nos hospitais, como relatado no World Report da Lancet.

[Comment] FIGO position paper: how to stop the caesarean section epidemic

The Lancet - Sa, 13/10/2018 - 00:00
Worldwide there is an alarming increase in caesarean section (CS) rates. The medical profession on its own cannot reverse this trend. Joint actions with governmental bodies, the health-care insurance industry, and women's groups are urgently needed to stop unnecessary CSs and enable women and families to be confident of receiving the most appropriate obstetric care for their individual circumstances.

[Comment] Appropriate use of caesarean section globally requires a different approach

The Lancet - Sa, 13/10/2018 - 00:00
Increasing global rates of caesarean section are debated because of evidence that medically unnecessary caesarean sections are associated with worse outcomes for mothers and their children.1 There is consensus that caesarean sections are overused in some countries and underused in others. As Ties Boerma and colleagues2 report in this Lancet Series on optimising caesarean section use,1–3 there are unacceptable disparities: caesarean section rates of 44% in Latin America and the Caribbean compared with 4·1% in western and central Africa.

[Comment] Strategic measures to reduce the caesarean section rate in Brazil

The Lancet - Sa, 13/10/2018 - 00:00
Quality health care during deliveries and births is essential for reducing maternal and neonatal morbidity and mortality. Birth should not be treated as a set of medical procedures, but as a physiological act, an important family and cultural event, and a unique time between mother and child. In Brazil, 98% of women have their babies in hospitals.1,2 Such progress has not, however, ensured more favourable perinatal outcomes and public policies need to be adopted to ensure quality maternal health care.

[Comment] Lancet Commission on the Value of Death

The Lancet - Sa, 13/10/2018 - 00:00
Without death every birth would be a tragedy. “We die so that others may live, we grow old so that others may be young”, writes the poet Kate Tempest.1 Yet medicine continues to strive to keep patients with life-limiting illnesses alive, often beyond the point of benefit. Many people in high-income countries, and those in poorer countries who are able to access quality health care, have an uneasy relationship with death, unlike some traditional societies.2 Serious people hold out the prospect of immortality,3 while dying baby boomers want as long a life as possible, symptom control, and a personalised death—a combination that may be unachievable.

[Comment] Offline: The media—“from utopia to dystopia”

The Lancet - Sa, 13/10/2018 - 00:00
Doctors and scientists love to slam the “media”—newspaper and broadcast journalists who, they allege, twist, spin, and distort science into mortal scares or exaggerated breakthroughs. Journalists and especially their editors, so scientists often say, trade in sensationalism to drive sales. It's a common claim. But eavesdrop on some of those same journalists and editors and you will hear a different story. Last week, at the Independent Television (ITV) studios in London, the Responsible Media Forum (not an oxymoron) convened 150 media professionals to discuss whether they were “mirrors or movers”.
