When patients are discharged from the intensive care unit it’s great news for everyone. However, it doesn’t necessarily mean the road to recovery is straight. As breakthroughs and new technology increase the survival rate for highly critical patients, the number of possible further complications rises, meaning life after the ICU can be complex.
The field of anaesthesia is a subtle discipline, when properly applied the patient falls gently asleep, miraculously waking-up with one less kidney or even a whole new nose. Today, anaesthesiologists have perfected measuring the depth and risk of anaesthesia, but these breakthroughs were hard-won.
Meet Utricularia. It’s a bladderwort, an aquatic carnivorous plant, and one of the fastest things on the planet. It can catch its prey in a millisecond, accelerating it up to 600g.
From the comfort of a desk, looking at a computer screen or the printed page of a newspaper, it is very easy to ignore the fact that thousands of tons of insecticide are sprayed annually. Consider the problem of the fall armyworm in Mexico. As scientists and crop advisors, we’ve worked for the past two decades trying to curb its impact on corn yield.
When we think of Obsessive Compulsive Disorder or OCD for short, lots of examples spring to mind. For example, someone who won’t shake your hand, touch a door handle, or borrow your pen without being compelled to wash their hands, all because of a fear of germs.
It is becoming widely accepted that women have, historically, been underrepresented and often completely written out of work in the fields of Science, Technology, Engineering, and Mathematics. Explanations for the gender gap in STEM fields range from genetically-determined interests, structural and territorial segregation, discrimination, and historic stereotypes. With free Oxford University Press content, we tell the stories and share the research of both famous and forgotten women.
Vladimir Ilich Ulyanov (aka Lenin) died on this day 90 years ago with cerebral vessels so calcified that when tapped with tweezers, they sounded like stone. He was only 53. He hadn’t smoked and, in fact, had prohibited smoking in his presence.
Introduction, from Michael Alvarez, co-editor of Political Analysis Recently I asked Nathaniel Beck to write about his experiences with research replication. His essay, published on 24 August 2014 on the OUPblog, concluded with a brief discussion of a recent experience of his when he tried to obtain replication data from the authors of a recent […]
Modern science has introduced us to many strange ideas on the universe, but one of the strangest is the ultimate fate of massive stars in the Universe that reached the end of their life cycles. Having exhausted the fuel that sustained it for millions of years of shining life in the skies, the star is no longer able to hold itself up under its own weight, and it then shrinks and collapses catastrophically unders its own gravity. Modest stars like the Sun also collapse at the end of their life, but they stabilize at a smaller size.
Head hits cause brain damage, but not always. Should we ban sport to protect athletes? Exposure to electromagnetic fields is strongly associated with cancer development. Should we ban mobile phones and encourage old-fashioned wired communication? The sciences are getting more and more specialized and it is difficult to judge whether, say, we should trust homeopathy, fund a mission to Mars, or install solar panels on our roofs.
How are we to understand experiences of depression? First of all, it is important to be clear about what the problem consists of. If we don’t know what depression is like, why can’t we just ask someone who’s depressed?
Wolves in the panhandle of southeast Alaska are currently being considered as an endangered species by the US Fish and Wildlife Service in response to a petition by environmental groups. These groups are proposing that the Alexander Archipelago wolf (Canis lupus ligoni) subspecies that inhabits the entire region and a distinct population segment of wolves on Prince of Wales Island are threatened or endangered with extinction.
Given that we see yoga practically everywhere we turn, from strip-mall yoga studios to advertisements for the Gap, one might assume a blanket acceptance of yoga as an acceptable consumer choice. Yet, a growing movement courts fear of the popularization of yoga, warning that yoga is essentially Hindu.
“Sorry mate, I didn’t see you”. It’s a common refrain heard after many a road-traffic collision, describing the frequent type of motorbike accident when a car pulls out at an intersection. It turns out that these sorts of events might be more complicated than they first appear. These sorts of situational awareness failures may in fact result from a well-described, but not well-known, psychological phenomenon called inattentional blindness.
About 500,000 Canadians are living with Alzheimer’s disease or a related dementia. This number is expected to soar to 1.1 million within 25 years. To date, there is no definitive way for health care professionals to forecast the onset of dementia in a patient with memory complaints.
A previous piece (“Patterns in Physics”) discussed alternative “representations” in physics as akin to languages, an underlying quantum reality described in either a position or a momentum representation. Both are equally capable of a complete description, the underlying reality itself residing in a complex space with the very concepts of position/momentum or wave/particle only relevant in a “classical limit”. The history of physics has progressively separated such incidentals of our description from what is essential to the physics itself.
