Merging sociality and robotics through an evolutionary perspective
Robotics, using social mechanisms like hormonal modulation, may accelerate our understanding of core sociality principles. By looking at social robotics through an evolutionary lens, we propose this field as a promising framework to investigate the fundamental bricks of sociality from an evolutionary…

Calcium-dependent regulation of auxin transport in plant development
The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

COMMUNITY: unraveling the regulatory networks in Streptomyces that switch on antibiotic production on demand
Through his project we will unravel the global regulatory networks that control gene expression in Streptomyces bacteria and allow them to properly respond to major changes in the environment; we will then harness this knowledge to activate and identify novel antibiotics

Unwiring beneficial functions and regulatory networks in the plant endosphere
How do plants lure microscopically small 'support teams' into their roots for protection against diseases? And what functions are activated in the microbes and the plants?

Pavlov revisited. About the placebo effect of rose scent
Health psychologist Aleksandrina Skvortsova has made clever use of the Pavlov effect to link the ‘cuddle’ hormone oxytocin with the placebo effect. This effect can alter the level of oxytocin in the body, making it possible for people to reduce the amount of medicine they need while still feeling good.…

Group behaviour: one for the team
Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

What to focus on for a clean environment?
The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

Stem cells as cure
Leiden has a long history in the treatment of blood cell cancer. Research to find better therapies never stands still. One of the potential treatments currently being worked on is a ‘living medicine’.

Education and Child Studies
How do people develop and how do they learn? How does their environment affect them? How do we ensure that they develop in optimal fashion? And what can we do if problems occur? These are questions that the researchers at the Institute of Education and Child Studies try to answer.

What happens to the brain when you become a mother?
May 12 is Mother's Day in many countries. Becoming a mother is no mean feat: brain scientist Elseline Hoekzema has shown that a woman's brain changes drastically during pregnancy. She explained how in TV show De Kennis van Nu.

Tracking genes to fight breast cancer
PhD student Esmee Koedoot studied the underlying processes responsible for metastases in a dangerous type of breast cancer. She hopes to find new possibilities to fight the disease. In December 2019 she obtained her doctorate cum laude.

Psychology Connected over gender differences: 'More research done on extraterrestrial life than the female body'
In medical and psychological sciences, little research has been specifically conducted on women. Hormonal fluctuations were considered too intricate. Yes, research into sex and gender differences is complex, acknowledge neuroscientists Ellen de Bruijn and Lara Wierenga, but that’s precisely why it's…

How oxygen deprivation causes cancer cells to spread
In breast cancer, metastasis rather than the primary tumour is the cause of death. A lack of oxygen in the tumour cells promotes this metastasis, accompanied by a reprogramming of the cell's metabolism. PhD candidate Qiuyu Liu investigated these alterations to get more knowledge about the actionable…

Placebo research: Pharmacological conditioning
The major aim is to examine the potential of learning the body to produce a similar physiological (autonomic, neuroendocrine, or immune) and physical (e.g., desensitization of persistent physical symptoms) response to placebo medication than to active medication (pharmacological conditioning). If proven…

Butterflies’ wing patterns change with the seasons
Tropical butterflies adapt to their environment to improve their chances of survival. The changes are triggered by hormone signals that transmit information about temperature to the butterflies' tissues.

What plant genes can teach us
Just like us, plants also produce growth hormones, and they also go through an ageing process. The study of the genes and mechanisms behind these processes is useful not only for crop breeding and agriculture, but also for medical research. That is the view held by Professor of Plant Developmental Genetics…
