Ceremony, joy and world-class research as KI honours its new professors

At the installation ceremony for KI’s 22 new professors, Aula Medica was filled with music, laughter and academic pride. The annual professorial installation is as much a tribute to knowledge, diversity and research as it is a ceremonial occasion. Also honoured during the evening were the recipients of various awards, including KI’s Grand Silver Medal, Silver Medal and the Lennart Nilsson Award.

Nobel Prize rewards key to future MS and cancer treatment

The year’s Nobel Prize in Physiology or Medicine rewards discoveries that reveal how our immune system is kept in check – in other words, how the body protects itself from attack by its own immune cells. The discoveries pave the way for possible new therapies for many conditions, including autoimmune diseases like type 1 diabetes, MS and cancer.

New study

AI can improve cervical cancer screening in low-resource settings

Access to cervical cancer screening in low- and middle-income countries can be improved with the help of AI, according to a new study published in The BMJ. However, the technology requires support from functioning healthcare systems to be effective.

New study

The immune system is more dynamic than previously thought

Researchers have discovered that some natural killer cells, NK cells, temporarily reside in our organs and then leave them via the lymphatic system. The results may contribute to better treatments that direct the immune system where it is needed.

New study

Stomach acid medicine tied to higher infection risk in pregnancy

Pregnant women who use proton pump inhibitors, a common medicine for heartburn, run a slightly higher risk of developing infections during pregnancy and after childbirth. This is shown in a new registry study from Karolinska Institutet, published in the journal The Lancet Obstetrics, Gynaecology & Women’s Health.

New study

POTS common in patients with long COVID

A new study from Karolinska Institutet shows that a heart rhythm disorder, POTS, is particularly common in people with long COVID. The majority of those affected are middle-aged women.

New study

Poor sleep may accelerate brain ageing

People who sleep poorly are more likely than others to have brains that appear older than they actually are. This is according to a comprehensive brain imaging study from Karolinska Institutet, published in the journal eBioMedicine. Increased inflammation in the body may partly explain the association.

New study

Simple test can predict risk of severe liver disease

A new study from Karolinska Institutet, published in the scientific journal The BMJ, shows how a simple blood analysis can predict the risk of developing severe liver disease. The method may already start to be applied in primary care to enable the earlier detection of cirrhosis and cancer of the liver.

Increased risk of depression and psychosis after childbirth

Depression and psychosis are more common in women after childbirth than before, but the risk of suicide attempts decreases, according to two new studies. The results suggest that national guidelines for screening can help women get help earlier.

Paracetamol use during pregnancy not linked to autism in large study

A study of nearly 2.5 million births in Sweden published in JAMA in 2024 shows no evidence that paracetamol (acetaminophen) use during pregnancy increases a child’s risk of autism. This is the largest study conducted on the subject to date.

Do all heart attack patients need beta blockers? A cardiologist explains

Beta blockers have long been prescribed to almost everyone who has suffered a heart attack, but new research shows that their effect depends on the heart's pumping capacity. While some patients clearly benefit from the treatment, it appears to be unnecessary—or even risky—for others. Read the news article in The Conversation.

Tumour cells exploit damaged tissue in the pancreas

Pancreatic cancer is one of the most aggressive cancer types. New research shows that tumour cells grow not only in the connective tissue-rich environment typical of the disease, but also in damaged parts of the pancreas where normal tissue is altered. This may play a role in how the tumour responds to treatment.

Quantum technology at KI

Martin Bergö: “We owe it to humankind to use this technology”

The first revolution in quantum technology paved the way for mobile telephony and GPS navigation. With its extreme computational capacity, the technique is now of interest to the field of life science and could prove the key to such advances as smarter drug development and optimised therapies to treat cancer and neurodegenerative diseases such as Alzheimer’s. By virtue of its involvement in the Swedish Quantum Life Science Centre, KI is a driver of the country’s research in the field.
