Millions of colonies of farmed bees are used to help pollinate crops. It turns out they can escape and mate with local bees, producing offspring that may be vulnerable to climate change

Creepy human-like skin makes your phone ticklish and pinchable

A smartphone case made from artificial human-like skin responds to being pinched, tickled and stroked to add an extra layer of interactivity to the device

[Editorial] Child nutrition: the need for courageous action

The Lancet - Sa, 19/10/2019 - 00:00
Dame Sally Davies has stepped down as Chief Medical Officer for England, using her final report to make strong and ambitious recommendations for the UK to stem childhood obesity. Her proposals include a cap on the calories per serving for food sold in restaurants and takeout outlets, a ban on eating and drinking on public transport, and the possibility of introducing plain packaging for unhealthy foods, similar to that used with success for tobacco. Nearly a third of young people aged 5–19 years in the UK are overweight or obese.

[Editorial] Canada needs universal pharmacare

The Lancet - Sa, 19/10/2019 - 00:00
Canada's often-lauded health-care system has an unusual and unfortunate distinction. Physician care and hospital stays are universally publicly funded, but medicines are not. Canada is the only country in the world with public health care and no universal public system for providing prescription drugs (pharmacare). In the run-up to the country's federal election on Oct 21, the harms to Canadians, and the costs to the health-care system, of the absence of national pharmacare are again in the spotlight.

[Editorial] A vision for universal eye health

The Lancet - Sa, 19/10/2019 - 00:00
World Sight Day, Oct 10, 2019, opened the final stages of Vision2020 and the Global Action Plan, two global advocacy initiatives that strived to tackle the global burden of avoidable blindness and vision impairment. 80% of vision impairment is preventable or treatable, yet it affects millions of people, and many have no access to affordable, good-quality eye care. WHO's first World Report on Vision, released on Oct 8, 2019, suggests how to meet the world's growing eye care needs.

[Comment] Will alcohol harm get the global response it deserves?

The Lancet - Sa, 19/10/2019 - 00:00
For the first time since the endorsement in 2010 of the WHO global strategy to reduce harmful use of alcohol,1 alcohol had a place on the World Health Assembly (WHA) agenda. At the 2019 WHA, it was agreed that the WHO Director-General will report on “the implementation of WHO's global strategy to reduce the harmful use of alcohol during the first decade since its endorsement, and the way forward” to the WHA in 2020.2 This move comes after several years of civil society and some member states working cooperatively to raise the profile of alcohol at the WHA.

[Comment] Offline: The necessity of the engaged scientist

The Lancet - Sa, 19/10/2019 - 00:00
What should we expect of scientists in society? To do great science for sure. But to demand more is surely unreasonable. When medical journals publish research on war, the climate crisis, migration, Brexit, President Trump, and even notions of social justice, for some readers we clearly violate a principle that they hold dear—that science and politics do not mix, and certainly should not be mixed in the pages of a medical journal. I remember one ardent (and knighted) advocate of evidence-based medicine saying that journals should focus only on publishing the best available science.

[Perspectives] Testament to the times

The Lancet - Sa, 19/10/2019 - 00:00
Why has Margaret Atwood gone back to Gilead now? The world of 2019 is, superficially, a very different place for women than it was in 1985, when The Handmaid's Tale—the precursor to The Testaments—was published. That novel came out at the fag-end of feminism's second wave and as the backlash was surging. In the USA, which is the site of Atwood's Gilead, external opposition and internal divisions had left the women's movement scattered. Popular culture—in the form of primetime television, evangelical preachers, and bad-science bloviators—was fomenting a back-to-the-home doctrine for women.

[Perspectives] Senait Fisseha: empowering women through reproductive health

The Lancet - Sa, 19/10/2019 - 00:00
It is a long way from Addis Ababa, Ethiopia, to Omaha, Nebraska, USA, but for Senait Fisseha, Director of International Programmes at the Susan T Buffett Foundation, it is where she exerts great influence in global reproductive health. “I came here to have impact. At the Foundation I oversee grant-making for reproductive health programmes on a global scale, an incredible opportunity for me to contribute to the reproductive rights and health of women around the globe”, she says. Fisseha is clear about the Foundation's role.

[Perspectives] Medical history at Apothecaries' Hall

The Lancet - Sa, 19/10/2019 - 00:00
On Oct 21, 1959, the establishment of the Faculty of the History and Philosophy of Medicine and Pharmacy was announced by the UK's Worshipful Society of Apothecaries. Its founding aim was “to foster and extend more general interest in medical history and to attract the co-operation of general historians, so that work in this field may be co-ordinated with wider historical studies”. On the Faculty's diamond anniversary, it's timely to reflect on the pursuit of this aim, especially from a personal perspective since from April, 2019, I've served as a “general historian” Faculty President, the 19th person to hold the post.

[Correspondence] The need for a global committee on academic behaviour ethics

The Lancet - Sa, 19/10/2019 - 00:00
Academic bullying and the complexity that surrounds it are dramatically increasing.1 Academic institutions play a key role in minimising different types of academic bullying by improving their fair and thorough reporting systems with no fear of reprisal.2,3 Although most institutions claim to use a fair and robust process to address academic bullying, they are ill equipped to handle such cases, with departments such as ombuds offices being responsible for informally addressing the issue. Fear of tarnishing their own reputation might subject institutions to bias, so the actions they take against bullying could not only be insufficient, but also of questionable neutrality and independence, raising the possibility that incomplete investigations might potentially be encouraged.

[Correspondence] Academic medicine and political agendas

The Lancet - Sa, 19/10/2019 - 00:00
Paul Gideon and colleagues1 suggest that the term occupied Palestinian territory is a “political statement with intentional prejudice” and should be avoided in medical academic papers. However, they use an alternative term, disputed territories, to describe the West Bank and Gaza Strip. This term is only used by the Government of Israel and always in the service of Israel's political aims.

[Correspondence] Academic medicine and political agendas

The Lancet - Sa, 19/10/2019 - 00:00
We disagree with Gideon Paul and colleagues1 in their assertion that academic research should not be divisive. Divisive is a subjective term and at times, if research examines or illuminates factors underlying conflict and its impact on populations, it could be seen by some as being divisive. For example, during the USA-backed war on Nicaragua's Sandinista Government, researchers documented the effects on the civilian population, helping to inform the policy debate;2,3 this certainly did not please advocates of US policy.

[Correspondence] The YOMEGA non-inferiority trial

The Lancet - Sa, 19/10/2019 - 00:00
I read with interest the Article by Maud Robert and colleagues1 reporting a randomised clinical trial comparing the outcomes of one anastomosis gastric bypass (OAGB) with Roux-en-Y gastric bypass (RYGB) at 2 years' follow-up. Despite being an interesting topic for investigation and discussion, several aspects make the results questionable. First, they did a non-inferiority trial, which in my opinion might have been the wrong study design, as two previous randomised clinical trials and three meta-analyses2–4 have reported a superiority of OAGB in terms of weight loss and remission of comorbidities.

[Correspondence] The YOMEGA non-inferiority trial

The Lancet - Sa, 19/10/2019 - 00:00
High-quality randomised controlled trials are rare in the field of surgery, so Maud Robert and colleagues, the authors of the YOMEGA1 non-inferiority study, should be congratulated. However, if we agree that a per-protocol analysis is a common rule in non-inferiority trials, it is difficult to understand why the authors performed multiple imputation on 22·5% of the patients who were lost to follow-up at 2 years. These patients did not pertain to the per-protocol population and an imputation of their data could make the two groups more identical.
