Cyanobacterial blooms can also occur at colder temperatures, even under ice
Mass developments of cyanobacteria, so-called blue-green algae blooms, repeatedly threaten the quality of water bodies and drinking water resources worldwide. Cyanobacteria are considered to be heat-loving, and massive algal blooms are reported mainl.....»»
Scientists propose guidelines for solar geoengineering research
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the sun and offset Earth's warming temperatures. But they also want to ensure that the solar geoengineering.....»»
Study uncovers condensed-matter dark states in a quantum system with two pairs of sublattices
Dark states are quantum states in which a system does not interact with external fields, such as light (i.e., photons) or electromagnetic fields. These states, which generally occur due to interferences between the pathways through which a system int.....»»
Most ransomware attacks occur between 1 a.m. and 5 a.m.
There’s been an alarming increase in ransomware attacks over the past year, alongside significant shifts in the tactics and strategies employed by cybercriminals that underscore the necessity for organizations to implement around-the-clock moni.....»»
Bulwark of blooms: The lily"s secret armor against plant pathogens
Fusarium wilt is a severe threat to the global cut-flower industry, particularly impacting lilies. Caused by Fusarium oxysporum, this disease results in significant economic losses due to plant decay and death. Traditional breeding methods have strug.....»»
From embers to crisis: The expanding threat of wildfires under global warming
Globally, wildfires are on the rise, driven by climate change, which exacerbates droughts and high temperatures. These fires contribute significantly to carbon emissions and particulate matter (PM2.5), with severe consequences for both climate stabil.....»»
The overshoot myth: We can"t keep burning fossil fuels and expect scientists of the future to get us back to 1.5°C
Record breaking fossil fuel production, all-time high greenhouse gas emissions and extreme temperatures. Like the proverbial frog in the heating pan of water, we refuse to respond to the climate and ecological crisis with any sense of urgency. Under.....»»
Ancient civilizations had ways to counter the urban heat island effect—how history"s lessons apply to cities today
As intense heat breaks records around the world, a little-reported fact offers some hope for cooling down cities: Under even the most intense periods of extreme heat, some city blocks never experience heat wave temperatures......»»
Animals with higher body temperatures are more likely to evolve into herbivores, study finds
A University of Arizona study has uncovered a surprising relationship between an animal's body temperature and its likelihood of evolving into an herbivore. The study, published in the journal Global Ecology and Biogeography, offers fresh insights in.....»»
Specialized materials could passively control the internal temperature of space habitats
Areas of space have wildly different temperatures depending on whether they are directly in sunlight or not. For example, temperatures on the moon can range from 121 °C during the lunar "day" (which lasts for two weeks), then drop down to -133 °C a.....»»
The Run of Record-Breaking Heat Has Ended, for Now
Air temperatures in July 2024 were fractionally cooler than in July 2023, probably because of a waning El Niño. But don’t expect things to be much cooler in coming years......»»
During a heat wave, temperatures not the only threat: expert
Spain has just emerged from a 21-day heat wave that engulfed Madrid, Barcelona and Zaragoza, posing a health threat which extends far beyond the actual temperature, according to Julio Diaz, a researcher at Madrid's Carlos III Health Institute......»»
Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes
Warming water temperatures and increased nutrient levels are putting freshwater ecosystems at serious risk, new research has revealed......»»
"Mercury bomb" threatens millions as Arctic temperatures rise, study warns
The Yukon River flows west across Alaska toward the Bering Sea, eroding Arctic permafrost along its banks and transporting sediment downstream. Within that sediment lurks a toxic stowaway: mercury......»»
M4 MacBook Pro updates could be imminent with display shipments starting
Rumors haven't been able to nail down when an M4 MacBook Pro refresh would occur, but display shipments from the supply chain could indicate an impending announcement in the fall.MacBook ProThe rumor mill believes that Apple will be bringing out a bu.....»»
Tree mortality may lead to carbon tipping point in the Amazon by 2050s
The Amazon rainforest is home to a diverse cast of plants and animals. This vital, verdant landscape also plays a crucial role in managing the effects of climate change by storing significant amounts of carbon and helping regulate temperatures and ra.....»»
Lewis-base ligand optimized electrolyte composition enhances CO₂ electrolysis performance
The electrode-electrolyte interface where electrocatalytic reactions occur, buried between solid-catalysts and electrolytes, involves complicated processes of electron transfer and mass diffusion under an applied electric field. Understanding the int.....»»
Neutron-star mergers illuminate the mysteries of quark matter
Neutron stars are the remnants of old stars that have run out of nuclear fuel and undergone a supernova explosion and a subsequent gravitational collapse. Although their collisions—or binary mergers—are rare, when they do occur, these violent eve.....»»
Mediterranean Sea temperatures match 2023 records
The temperatures of the Mediterranean Sea in recent days have reached heat records set last summer, the main Spanish maritime research center told AFP Tuesday, with marine heat waves in some places exceeding 30 degrees Celsius......»»
Novel anemometer tracks sound travel for speedier, more precise wind speed calculations on Mars
Mars has a notoriously inhospitable environment, with temperatures that fluctuate dramatically over the course of a Martian day and average minus 80 degrees Fahrenheit. Its surface is mostly covered in red dust, with terrain typified by craters, cany.....»»
Researchers highlight the carbon-saving potential of compact cities
In recent years, the dramatic rise in extreme weather events due to climate change has escalated what was once termed "climate change" into a "climate crisis." With global average surface temperatures reaching unprecedented levels, the urgency to tra.....»»
