In her thesis, obstetrician Berith Karlsson Tingåker has examined the source of pain during childbirth and how uterine sensitivity to pain changes during pregnancy. Her results show that labour pains mainly derive from the cervix, where the number of pain-related nerve fibres and receptors is much greater than in the uterus at full-term pregnancy.
Her thesis also shows that uterine pain sensitivity differs markedly between pregnant and non-pregnant women. In the latter, the entire uterus is pain-sensitive, while in the former, the pain-sensitive nerve fibres disappear almost completely from the main body of the uterus, but remain in the cervix.
Spinal anaesthesia is currently the most effective way of providing pain relief. However, it is a resource-demanding method and has other drawbacks that limit its practicability.
“The results create new opportunities for developing simpler and more effective methods of pain relief, with the focus on the cervix,” says Berith Karlsson Tingåker. “Women in Sweden and around the world, many of whom have no access to pain relief, are literally crying out for them.”

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
