If NYC subways obeyed quantum maths trains wouldn’t be delayed

New Scientist - Lu, 11/09/2017 - 18:28
New York's notoriously unreliable subway system isn’t all bad. Some lines follow statistical patterns seen in quantum systems, and run better for it

Rat brains seen replaying scary memories as they sleep

New Scientist - Lu, 11/09/2017 - 18:00
Could this be where nightmares come from? When rats are given a fright while awake, their brains go on to replay their fear when they next fall sleep

Tiny worm burrows may reveal when first complex animals evolved

New Scientist - Lu, 11/09/2017 - 18:00
Microscopic fossil burrows found in ancient rocks reveal that small worm-like animals existed more than half a billion years ago

Thousands of new lifeforms discovered that redraw tree of life

New Scientist - Lu, 11/09/2017 - 18:00
Over 90 per cent of microorganisms are unknown to science, but DNA analysis has unmasked thousands of them and made life's story far more complex

Slingshot around Titan is the beginning of the end for Cassini

New Scientist - Lu, 11/09/2017 - 15:33
The Cassini spacecraft is passing by Titan on its final nosedive into Saturn. Plenty has been revealed about Saturn’s largest moon on Cassini’s 20-year mission

Our sun probably didn’t steal Planet Nine from outer space

New Scientist - Lu, 11/09/2017 - 14:51
If there is a Planet Nine lurking in the outer reaches of our solar system, it was probably born close to the sun rather than snatched up from afar

App creates augmented-reality tutorials from normal videos

Want to fix your car or indulge in some molecular gastronomy? A system that generates the kind of AR tutorials that trains fighter jet engineers could help

Florida suffers coast-to-coast battering by Hurricane Irma

New Scientist - Lu, 11/09/2017 - 13:00
After striking the Caribbean islands and leaving several close to uninhabitable, Hurricane Irma has made landfall in Florida and caused untold damage

Democracy needs an upgrade to ensure it keeps people on its side

New Scientist - Lu, 11/09/2017 - 12:00
If an election winner gains fewer votes than the loser, the system is flawed. To stay the best mode of government, democracy needs to use new technology

Ankle fossil suggests our ancient ancestors leapt like acrobats

New Scientist - Sa, 09/09/2017 - 11:00
A 52-million-year-old ankle bone hints at first primates jumping rather than clambering from tree to tree – but what drove them to evolve this way is a mystery

[Editorial] Extreme rain, flooding, and health

The Lancet - Sa, 09/09/2017 - 00:00
The unprecedented volume of rain and floods during the past few weeks is difficult to comprehend. More than 1400 people in south Asia are dead and tens of millions more have been affected by extreme monsoon rains. The worst flooding in 100 years has left one third of Bangladesh submerged. In Nepal, almost half a million people are food insecure. More than 7000 schools have been damaged in India at the height of the exam season, with the result that many children will not complete their education.

[Editorial] Pushing the boundaries in paediatric surgery

The Lancet - Sa, 09/09/2017 - 00:00
Aside from the difficult psychosocial aspects of illness in babies and children, paediatric surgery and paediatric surgical research face inimitable challenges. These include the consequences of anaesthesia and radiation exposure in children, the implications of long-term complications, and, in many cases, the necessity of long-term care despite the inevitability of a transition to adult services. Diseases requiring paediatric surgery are sometimes rare and heterogenous in nature, with complex cases requiring multidisciplinary management.

[Editorial] CAR T-cells: an exciting frontier in cancer therapy

The Lancet - Sa, 09/09/2017 - 00:00
On Aug 30, the US Food and Drug Administration (FDA) approved tisagenlecleucel (marketed by Novartis as Kymriah) as the first ever treatment that genetically modifies patients' own T cells. The approval is for children and young adults (up to 25 years of age) with relapsed or refractory acute B-cell lymphoblastic leukaemia—a leading cause of childhood cancer deaths. This treatment option is currently limited to 20 specially certified centres in the USA because of the complexity of the procedure and potentially serious side-effects.

[Comment] Surgical trials for chronic pancreatitis

The Lancet - Sa, 09/09/2017 - 00:00
Chronic pancreatitis is associated with a heavy burden for patients and substantial economic costs.1,2 Patients with chronic pancreatitis might have debilitating pain, opioid dependence, and reduced quality of life; be recurrently admitted to hospital; and be unable to work.3,4 Yet, for patients and physicians, chronic pancreatitis remains a difficult disease to manage, with few medical options and little consensus on the optimum timing or type of surgical intervention. Reports5,6 suggest potential superiority of surgical intervention over endoscopic drainage for long-term pain relief.

[Comment] Long-term implications and global impact of paediatric surgery

The Lancet - Sa, 09/09/2017 - 00:00
Irrespective of variations across geography, culture, and socioeconomic status, paediatric surgery differs from other surgical subspecialties. Children are not small adults. Surgery for infants and children is typically undertaken for congenital, rare, and complex conditions and the consequences of both the condition and its treatment can affect that individual for life. Above all, the surgical outcome needs to stand the test of time.

[Comment] Offline: North Korea—the case for health diplomacy

The Lancet - Sa, 09/09/2017 - 00:00
President Trump's August 30 tweet was blunt: “Talking is not the answer!” He was referring to North Korea (the Democratic People's Republic of Korea, DPRK). “The US has been talking to North Korea, and paying them extortion money, for 25 years”, he wrote. Meanwhile, as punishment for North Korea's firing of a missile over Japan's Hokkaido island, UK Prime Minister Theresa May threatened further economic sanctions to end the DPRK's nuclear provocations. The goal of western nations, united with China and Russia on the UN Security Council, is to squeeze Pyongyang to such an extent that the regime capitulates, even collapses.

[World Report] High stakes for research in US 2018 budget negotiations

The Lancet - Sa, 09/09/2017 - 00:00
As Congress considers how to fund the government next year, scientists hope spending for research will not be curtailed. Susan Jaffe, The Lancet's Washington correspondent, reports.

[Perspectives] The best editors get fired

The Lancet - Sa, 09/09/2017 - 00:00
Jerry Kassirer was fired as Editor-in-Chief of The New England Journal of Medicine (NEJM) in 1999. Two decades later, he has written, in the guise of a memoir, a blistering attack on his former employer, the Massachusetts Medical Society. Revenge, it is often said, is a dish best served cold. Kassirer relives old battles and settles outstanding scores. He savages the present state of medicine and medical journals. And he offers a bleak view of the future for a profession he clearly loves. Unanticipated Outcomes: A Medical Memoir is a painful autoautopsy of a successful life brought down by the greed of small minds and the tripwire of personal foible.

[Perspectives] The history of anaesthesia and the patient—reduced to a body?

The Lancet - Sa, 09/09/2017 - 00:00
“When the dreadful steel was plunged into my breast…I needed no injunctions not to restrain my cries”, writer Fanny Burney famously wrote about the mastectomy she underwent on the hands of Napoleon's surgeon Dominique-Jean Larrey on Sept 30, 1811. “I began a scream that lasted unintermittingly during the whole time of the incision—& I almost marvel that it rings not in my Ears still! So excruciating was the agony.” This account is very different from what happened when, on Dec 21, 1846, the 36-year-old butler Frederick Churchill had his thigh amputated by Robert Liston using ether as an anaesthetic.
