Winter precipitation and temperature constrain distribution of cedrus plants
The genus Cedrus Trew (Pinaceae) compromises four species of evergreen coniferous trees, which have important cultural, aesthetic, scientific and economic values. The four species are disjunctively distributed in the Mediterranean region and western.....»»
Study analyzes potato-pathogen "arms race" after Irish potato famine
In an examination of the genetic material found in historic potato leaves, North Carolina State University researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish.....»»
Streetlights running all night makes leaves so tough that insects can"t eat them, threatening the food chain
Light pollution disrupts circadian rhythms and ecosystems worldwide—but for plants, dependent on light for photosynthesis, its effects could be profound. Now scientists writing in Frontiers in Plant Science have found that exposure to high levels o.....»»
Kids" sport always cancelled due to rain-soaked grounds? Green infrastructure can help
It's been a rainy winter in many parts of Australia, wreaking havoc on kids' sporting competitions. As mums, it has been frustrating to see so many of our kids' sports matches (and training sessions) canceled because of waterlogged grounds......»»
New research sheds light on relationships between plants and insects in forest ecosystems

The effects of whole genome duplication on the plant metabolome
Whole genome duplication (WGD) is a common mutation in plants with profound evolutionary potential. While it is well-known that an increase in genetic material can lead to larger cell sizes, the impact of gene dosage multiplication on the metabolome.....»»
Ancient Antarctic microorganisms are aggressive predators
In Antarctica there is a small lake, called Deep Lake, that is so salty it remains ice-free all year round despite temperatures as low as -20°C in winter. Archaea, a unique type of single-celled microorganism, thrive in this bitterly cold environmen.....»»

New study reviews progress in ternary hydrogen-rich superconductors
Room-temperature superconductivity has been a century-long-held dream of scientists. Hydrogen-rich compounds at high pressures are predicted to be potential high-temperature and even room-temperature superconductors and have become one of the superco.....»»
Getting to the root of a plant"s success
Plants are powerful factories—they can turn basic ingredients like carbon dioxide, water, and sunlight into oxygen, sugars, and plant mass. But plants don't do all of this work on their own......»»
Stem cell harmony: How solanaceae plants maintain homeostasis through receptor compensation
A pivotal study sheds light on the evolutionary conservation of stem cell homeostasis in Solanaceae, revealing how receptor compensation mechanisms ensure the continuous and orderly formation of plant organs. This research uncovers the genetic interp.....»»
Researchers discover high levels of non-coding RNAs in testes, suggesting new roles in sperm function and evolution
Researchers at the University of Toronto have mapped the spatial distribution of around 700 long non-coding RNAs, otherwise known as lncRNAs, in the testes. The team discovered much higher levels of lncRNAs in the testes than had been previously esti.....»»
Scientists convert bacteria into efficient cellulose producers
Bacteria produce materials that are of interest to humans, such as cellulose, silk and minerals. The advantage of producing bacteria in this way is that it is sustainable, takes place at room temperature and in water. A disadvantage is that the proce.....»»
NASA data shows July 22 was Earth"s hottest day on record
July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-.....»»
Air pollution makes it harder for bees to smell flowers
Contaminants can alter plant odors and warp insects’ senses, disrupting the process of pollination. Scientists are uncovering various ways that air pollution can interfere with the ability of insects to pollinate plants. (credi.....»»
Unlocking glucosinolates" potential: Enhancing nutrition and stress tolerance in Brassica crops
A research team has reviewed the potential of glucosinolates, compounds found in Brassicaceae plants like cabbage and broccoli, to enhance stress tolerance and provide health benefits through their hydrolysis products......»»
Plants" hidden allies: Root microbiota fight back against leaf-mining flies
Plants encounter various biotic stresses, with insect herbivory being particularly destructive. Traditional chemical insecticides used to combat these pests pose environmental and health risks......»»
Ensuring quality in tropical vegetables: Addressing chilling injury through antioxidant systems
