What do plants hear?

18.02.2020
The natural world is full of sounds: from the buzzing of bumble bees to the murmur of streams and the whistling of wind. Each of them provides us with important information, for instance, about a source of water, an impending danger, or an upcoming change in weather. And what about plants? Are they able to listen to the world around them? If so, where do they have ears? Dr Paweł Jedynak from the JU Department of Physiology and Plant Biochemistry gives us some insight into plant polyphony.

The price of coronavirus

11.02.2020
Since late December 2019, the outbreak of novel coronavirus (2019-nCoV) in central China has led to the deaths of nearly 500 people, thereby bringing the number of victims of the virus closer to the death toll caused by SARS in 2002/2003. The ongoing crisis will undoubtedly have serious consequences, not only for health care, but also society, politics and economy. We asked Adrian Brona from the JU Institute of the Middle and Far East to diagnose the signs of coronavirus infection in the Chinese economy.

Scientists discover the oldest material on Earth

23.01.2020
The Jagiellonian University has in its collection a fragment of the Murchison meteorite, which has recently been confirmed to contain the oldest known material on Earth: particles of cosmic dust created before the formation of the Solar System. In the past few days, an international research team published a paper in which they estimate these grains to be about seven billion years old.

JU archaeologists uncover the secrets of Mesa Verde

10.01.2020
Archaeologists from the Jagiellonian University have found out that some of the rock drawings made by Native Americans about 800 years ago in the canyons located in the border region between the US states of Colorado and Utah were linked to astronomic observations, such as determining the dates of summer and winter solstices. The pioneering archaeological research in this field has been led by Dr Radosław Palonka from the JU Department of American Archaeology.

How plants deal with stress

09.12.2019
Throughout their existence, human beings have been accompanied by stress, and hence they have developed various methods to reduce it. Plants are also subject to stress, caused by adverse environmental factors (such as water or light deficiency), but unlike most animals they cannot hide or run away from danger. Dr Paweł Jedynak from the JU Department of Plant Physiology and Biochemistry discusses how to recognise and interpret the symptoms of stress in plants and what are the mechanisms that allow them to live through stressful situations.
