Immune system ageing can be revealed by CT scan

Thymus may play a bigger role in the immune system of adults than was previously believed

18-Oct-2023 - Thymus, a small and relatively unknown organ, may play a bigger role in the immune system of adults than was previously believed. With age, the glandular tissue in the thymus is replaced by fat, but, according to a new study from LiU, the rate at which this happens is linked to sex, age and ...

Method to reveal undesired biological effects of chemicals

How do pollutants and other chemicals that we are exposed to affect our health?

02-Dec-2021 - Researchers from Linköping University in Sweden have applied a method to identify the proteins in the body affected by chemicals. The method can be used to discover at an early stage whether a substance has biological effects in an organism. They are in the water we drink, the food we eat and the ...

From nanocellulose to gold

Soft and biocompatible materials for optical, catalytic, electrical and biomedical applications

12-Aug-2020 - When nanocellulose is combined with various types of metal nanoparticles, materials are formed with many new and exciting properties. They may be antibacterial, change colour under pressure, or convert light to heat. "To put it simply, we make gold from nanocellulose", says Daniel Aili, associate ...

Bioelectronics at the speed of life

04-Nov-2016 - Our nerve and muscle cells send signals to each other using ions and molecules. Certain substances, such as the neurotransmitter GABA (gamma aminobutyric acid), are important signal substances throughout the central nervous system. Eighteen months ago, researchers at the Laboratory of Organic ...

Relief for epilepsy at the scale of a single cell

Chemical stimulation and electrical sensing at the same site

24-Aug-2016 - Researchers at Linköping University have developed in collaboration with French colleagues a small device that both detects the initial signal of an epileptic attack and doses a substance that effectively stops it. All this takes place where the signal arises - in an area of size 20×20 μm known ...

Chemical signal can make it easier to personalize medication

27-Jun-2016 - Common diseases like allergy, diabetes and other immune diseases have increased dramatically in recent decades. This indicates that the environment may have a more important role than genes in explaining this increase. An international research team led by the Centre for personalized medicine at ...

Electronic plants developed

24-Nov-2015 - Researchers at Linköping University in Sweden have created analog and digital electronics circuits inside living plants. The group at the Laboratory of Organic Electronics (LOE), under the leadership of Professor Magnus Berggren, have used the vascular system of living roses to build key ...

The first chemical circuit developed

31-May-2012 - The Organic Electronics research group at Linköping University previously developed ion transistors for transport of both positive and negative ions, as well as biomolecules. Tybrandt has now succeeded in combining both transistor types into complementary circuits, in a similar way to traditional ...

Few genes control neuronal function

15-Mar-2012 - How are 100 billion cells created, each with specific duties? The human brain is evidence that nature can achieve this. Researchers at Linköping University have now taken a step closer to solving this mystery."Knowledge about the mechanisms that diversify neurons and keep them diverse is ...

One step closer to an artificial nerve cell

09-Jul-2009 - Scientists at the Swedish medical university Karolinska Institutet and Linköping University are well on the way to creating the first artificial nerve cell that can communicate specifically with nerve cells in the body using neurotransmitters. The technology has been published in an article in ...
