The effective treatment of schizophrenia has long presented a challenge to clinicians and scientists. Common misunderstandings around symptoms and behaviors, and inadequate approaches to diagnosis and physiology, have hindered significant progress for patients and professionals.
In 1980, Walter Alvarez and his group at the University of California, Berkeley, discovered a thin layer of clay in the geologic record, which contained an anomalous amount of the rare element iridium. They proposed that the iridium-rich layer was evidence of a massive comet hitting the Earth 66 million years ago, at the time of the extinction of the dinosaurs. The Alvarez group suggested that the global iridium-rich layer formed as fallout from an intense dust cloud raised by the impact event.
Functional disorders are one of the most common reasons for attendance at the neurology clinic. These disorders — at other times and in other places called psychogenic, non-organic, conversion or hysterical — encompass symptoms such as paralysis, tremor and other abnormal movements, gait disorders and seizures.
Hop (Humulus lupulus L.) is an essential ingredient for brewing beer, and contributes a characteristic bitterness, aroma, and fullness. However, during the Middle-Ages, various other herbs including Rhodomyrtus tomentosa and Salix subfragilis, had also been used for brewing beer in Europe.
It was a simple request: “Try and put the fun back into microbiology”. I was about to write a new practical course for first year students, and apparently there had been complaints that microbiology is just another form of cookbook chemistry. Discussions showed that they liked the idea of doing their own experiments without a pre-determined outcome. Of course, with living microorganisms, safety must be a major concern, and some control was needed to prevent hazardous surprises, but “fun” and safety are not mutually exclusive.
Parents of a child diagnosed with a serious illness are immediately required to make decisions about their child’s medical treatment which, in order to save life, may cause pain, unpleasant side-effects and risk damaging their child’s future quality of life. The actions, last summer, of the parents of five year old Ashya King offer just one example of the lengths to which parents will go to secure the best possible treatment for their child […]
The human brain might be perceived as an organ with two main strategic tasks: goal-directed motor behavior, and mental functioning in order to work out that goal. These two main functions have two prototypical diseases: Alzheimer disease, in case of mental function, and Parkinson’s disease, with motor function. Following its inception as an entity, Parkinson’s disease (PD) was long perceived to be a purely motor disorder with unimpaired mental functions.
Wrath, people say, is not an emotion but a sin; and a deadly sin at that. Yet anger is just as much an emotion as anxiety or misery. Like them, it is an inescapable part of life; like them, it can be necessary and useful; and like them, an excess can wreck lives. Mental health language, however, has not elevated the extreme into a syndrome comparable to depression or anxiety states.
Traumatic brain injury (TBI) has often been called the “signature wound” of the recent conflicts in the Middle East. While some tend to discuss TBI as an overarching diagnostic category, there is a plethora of evidence indicating that severity of TBI makes a large difference in the anticipated outcome.
Nipple of a cat. Nose of a pig. Hair of a poodle. Eyes of a baboon. Brain of a chimpanzee. If this sounds like a list of ingredients for a witches’ cauldron, think again, for it’s merely a reminder of how many general characteristics we share with other mammals. This similarity in basic body parts has a genetic basis. So humans and chimps share 99 percent DNA similarity in our protein–coding genes and even the tiny mouse is 85 percent similar to us in this respect.
In 1805 a Dorset farmer, Benjamin Jesty arrived in London on an invitation from the Original Vaccine Pock Institute to describe his cowpox vaccination procedure on his own family which included a real time inoculation of his son Robert with smallpox. This new institute was formed by the anti-Jenner physician George Pearson in an attempt to shift the credit for vaccination discovery away from Jenner.
Of the many controversies surrounding the life and legacy of Christopher Columbus, who died on this day 510 years ago, one of the most intriguing but least discussed questions is his true country of origin. For reasons lost in time, Columbus has been identified with unquestioned consistency as an Italian of humble beginnings from the Republic of Genoa. Yet in over 536 existing pages of his letters and documents, not once does the famous explorer claim to have come from Genoa.
On 18th May plant lovers around the world take part in Fascination of Plants Day to raise awareness of the importance of plant science to our lives. Well, what is so fascinating about plants? We asked some of our authors and editors to share why they think plants are fascinating and why they are worth studying.
As the 2016 presidential election season begins (US politics, unlike nature, has seasons that are two years long), we will once again see Republican politicians ducking questions about the validity of evolution. Scott Walker did that recently in response to a London interviewer. During the previous campaign, Rick Perry answered the question by observing that there are “some gaps” in the theory of evolution and that creationism is taught in the Texas public schools (it isn’t, of course).
We are still in the longest war in our nation’s history. 2.7 million service members have served since 9/11 in the conflicts in Iraq and Afghanistan. Thousands have been killed, tens of thousands wounded, and approximately 20 to 30% have post-traumatic stress disorder and/or traumatic brain injury.
This month marks 266 years since the birth of one of the most celebrated names in medical discovery. Edward Jenner, credited with the discovery of the smallpox vaccination, was born on 17 May 1749 (6 May by the Julian calendar, still in use in England by a quirk of anti-papal authoritarianism until 1752) in the village of Berkeley in Gloucestershire, England.
