Negative interest rates were once seen as impossible outside the realm of economic theory. However, recently several central banks have imposed such rates, with prominent economists supporting this move. This column investigates the actual effects of negative interest rates, taking evidence from the Swedish experience during 2015-2019. It is evident that the policy’s effect on the inflation rate w

Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive. This thesis and the work herein is part of an ongoing effort to map out the aggre

We argue that wars over natural resources, even if they are limited in their military scope, can have long-term consequences on the level and composition of public revenues. Military success in a resource war may lead to the annexation of natural resource-rich areas from enemy combatants, which provides the winning coalition with valuable and easy-to-tax sources of income. This, however, might dis

For classical tomography, it is essential that the sample does not change during the acquisition of one tomographic rotation. We derived and successfully implemented a tomographic reconstruction method, which relaxes this requirement of quasistatic samples. In the present paper, dynamic tomographic data sets are decomposed in the temporal domain by projecting to a lower dimensional subspace of bas

In 1822 the Parliament of the United Kingdom passed The Cruel Treatment of Cattle Act, which today is considered to be an important forerunner to modern animal protection and anti-cruelty legislation. However, the new Enlightenment attitudes to animals stemmed from an overly anthropocentric perception of the natural world and the place of the human animal in it. At the heart of the movement agains

Video capsule endoscopy (VCE), perfomed by ingesting a small vitamin-sized camera pill, was developed over a period of a couple of decades and –since its introduction in clinical practice at the dawn of the millennium– has become an essential tool in the diagnosis and management of small bowel (SB) diseases. At the same time, other fields such as minimally invasive diagnosis of other parts of the

Purpose of review: The main goal of this narrative review is to assess whether physical activity (PA) influences peak bone mass and fracture risk. Recent findings: Several randomized controlled trials (RCT) show that short-term PA intervention programs in childhood improve the accrual of bone mineral. There are now also long-term controlled PA intervention studies demonstrating that both boys and

Acetaminophen is one of the most common over-the-counter pain medications used worldwide and is considered safe at therapeutic dose. However, intentional and unintentional overdose accounts for up to 70% of acute liver failure cases in the western world. Extensive research has demonstrated that the induction of oxidative stress and mitochondrial dysfunction are central to the development of acetam
