Unusual blight-like symptoms appeared on highbush blueberry plants in Serbia during August 2015 and infected plants showed browning and reddening of leaves, drying of foliage and brown discolouration of internal vascular stem tissues. The objective of this study was to isolate and confirm a causal agent of the disease. Five diseased blueberry plants (2-year-old), with visible brown discolouration...
... Parthenocarpy and fruit malformations are common among independent transgenic tomato lines, expressing genes encoding different pathogenesis-related (PR) protein and antimicrobal peptides. Abnormal phenotype developed independently of the expression and type of target genes, but distinctive features during flower and fruit development were detected in each transgenic line.

Is it built around nurturing a bond with trees, animals, birds, and other life forms? Are students merely fed facts about greenhouse gases, ozone layer depletion, glacial melting, and soil erosion? Do they have opportunities to explore the outdoors, and participate in action-based projects? Is environmental studies a stand-alone subject, or is it woven into all the subjects taught?
In 2021, the United Nations Educational, Scientific and Cultural Organization (UNESCO) released an important open access publication titled Learn for our planet: A global review of how environmental issues are integrated in education. This document attempts to capture how biodiversity, climate change, sustainable development, and other environmental issues are reflected in the current education policies and curricula of 46 UN member states.
Through this study based on national curriculum frameworks and inputs from educators, the UNESCO learnt that “there is a continued focus on learning about climate and other environmental issues, as opposed to also developing the socio-emotional and action competences central for environmental and climate action.” Several respondents also revealed the absence of environment-related content in teacher training programmes.
Lofty goals become more easily attainable when we renew our own connection with the subject we teach; our joy and enthusiasm can be felt by our students. If you are looking for a resource that might catalyse such an experience for you, consider reading forester and author Peter Wohlleben’s book The Heartbeat of Trees: Embracing our Ancient Bond with Forests and Nature. It has been translated from German into English by Jane Billinghurst.
Do you agree? I do, to a large extent, because of the horrific manner in which human beings have plundered forests in the name of development. We exploit only when we fail to see interconnectedness and interdependence. We consider ourselves the pinnacle of evolution, so a sense of arrogance has set in. We think of other species largely in terms of what we can get from them, and we try to maximize our gains. We act without respect or responsibility.
Wohlleben’s book will hopefully change our blinkered view, and also our relationship with forests and nature at large. He is passionate about calling out humans for the destruction that we have caused but the book is far from being just a rant that runs into 264 pages. The author focuses on unravelling mysteries by posing simple questions and then answering them. He has a delightful writing style, which makes complex scientific concepts accessible.
If you grow tomato plants at home, and are curious about how they feel when they are stroked, Wohlleben clarifies that stroking them for a few minutes each day slows their upward growth and they divert their energy into growing thicker stems. “This, however, is not the plant saying it loves you, too, but rather the plant reacting to what it likely experiences as a breeze blowing by, because the wind elicits a similar response,” he writes.
As you turn the pages, you will find answers to a number of fascinating questions such as: Why do humans see the forest as green? How do trees communicate among themselves? What can spiders teach us about the electric fields that surround trees? How do fish detect the Earth’s magnetic field? Why can dogs sniff out many things much better than humans? How do trees disinfect their surroundings? Can plants differentiate types of music?
The author’s answers are based on either his observations in the forest or on the various scientific research studies that he has mentioned in the book. He names all the researchers and their institutional affiliations, so people can look them up. He also ensures that the information is not overwhelming; just enough to spark off curiosity, and satiate it to some extent, without getting into finer technical details that might be of value only to experts.
Wohlleben is critical of how sometimes forestry plays into the hands of powerful people who have no qualms about damaging the environment for immediate economic gains. They are not keen on seeing the big picture. He also seems aware that people cannot be shamed into being more prudent about the ways in which they use resources from nature. A smarter approach perhaps is to help them connect with nature so that they feel part of it.
Wohlleben shares that, when he facilitates tours for children, he asks them to yell as loudly as they can. The ones who are shy become less self-conscious during this exercise. According to him, this noise also calms down the animals in the forest because they are reassured that their human visitors are not threats. Besides, he tells children that they can get as dirty as they like because parents usually tend to make a fuss when clothes have dirt stains on them.
Sometimes, parents are worried because children might eat their lunch in the forest with dirty fingers. The author writes, “Is what we find on the forest floor really dirt? Of course not. It’s mineral-based soil combined with bits of humus – neither of which is poisonous or unhygienic.” He urges parents to join their children in digging around. Would you like to try this when you accompany students on a nature trail after the COVID-19 pandemic is over?
Wohlleben writes, “Children are wonderful teachers because they have no inhibitions about getting close to nature. If we manage to enjoy the forest as much as they do, perhaps that will help reinforce our tie to nature, which has become slightly worn of late.” When we feel connected, we will not need any external push to wake up and take swift action to reduce our carbon footprint. The motivation to conserve and coexist will come from within.

There are four separate grounds that are closely related... the AC ground for the two lines carrying AC power, the AC earth ground (third prong on your average AC power cord), the DC ground for the internal circuitry and apparent ground difference that may exist between multiple AC and/or DC circuits (notice I said "using different power circuits", which hints to the concept of a "floating ground")

That last one.... it can kill circuitry fairly easily.
