Caste differentiation in ants: How a specific hormone regulates the process
Scientists from the University of Copenhagen have revealed how a specific hormone regulates ant caste differentiation by phenotypic measurements of organ-level developmental changes and matching transcriptome analyses. Published in the Proceedings of.....»»
Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches
Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated from each other, even if they.....»»
In Patagonia, more snow could protect glaciers from melt—but only if greenhouse gas are curbed emissions soon
In an era of dwindling glaciers, Southern Patagonia has managed to hold on to a surprising amount of its ice. But, a new study in Scientific Reports from INSTAAR postdoc Matthias Troch suggests that this protective effect might be pushed up against i.....»»
Accessing the lesser known nucleon: New neutron measurement can help physicists learn about nucleon structure and spin
Protons and neutrons–known collectively as nucleons–are both the building blocks of matter, but one of these particles has received a bit more attention in certain types of nuclear physics experiments......»»
Exploring new liquid organic hydrogen carrier materials for a safer, more transportable energy source
To reduce CO2 emissions, the energy transition from a carbon-based energy system to a more sustainable system based on hydrogen energy is urgently needed. However, the nature of hydrogen (such as low volumetric density, flammability, and embrittlemen.....»»
Characterizing shifts in Sicily"s seasonal rainfall
Around the world, man-made climate change is increasing both the frequency and severity of extreme weather events. Seasonal patterns in rainfall are an especially important indicator of these changes: While a lack of rain can lead to more severe drou.....»»
Ancient meets modern as a new subway in Greece showcases archaeological treasures
Greece's second largest city, Thessaloniki, is getting a brand new subway system that will showcase archaeological discoveries made during construction that held up the project for decades......»»
Non-genetic reprogramming method to restore sweat gland function shows promise for burn victims
Sweat glands are vital for regulating body temperature, maintaining fluid balance, and supporting skin health. Yet, extensive skin injuries, such as burns, often result in the loss of these glands, leaving patients vulnerable to overheating, dehydrat.....»»
Oldest direct evidence of hot water activity on Mars found
New Curtin University-led research has uncovered what may be the oldest direct evidence of ancient hot water activity on Mars, revealing the planet may have been habitable at some point in its past......»»
Building climate resilient cocoa farming in West Africa
Agroforestry systems, which integrate trees and shrubs into farming, are vital to achieving sustainable cocoa production in West Africa where 70% of the world cocoa is produced. Climate change induced drought means that it is ever more critical to ad.....»»
Satellite data and algorithms reveal which ships emit excessive nitrogen
Ships are still emitting too much nitrogen oxide. Until now, it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. K.....»»
Peaches spread across North America through Indigenous networks, radiocarbon dating and document analysis show
Spanish explorers may have brought the first peach pits to North America, but Indigenous communities helped the ubiquitous summer fruit really take root, according to a study led by a researcher at Penn State......»»
On the trail of an 18th-century master forger: New evidence discovered
A document held in Göttingen University's Faculty of Humanities has been revealed as an 18th century forgery. The document purports to be from 1266, but mentions a church in Pisa that was not built until later. This discovery is the result of resear.....»»
Exploring the impact of offshore wind on whale deaths
In the winter of 2022–2023, nearly a dozen whales died off the coast of New Jersey, near the sites of several proposed wind farms. Their deaths prompted concern that related survey work being conducted in the area somehow contributed to their death.....»»
Natural substance from edible cyanobacterium could combat skin aging by enhancing collagen
Cyanobacteria, or blue-green algae, have existed for billions of years, adapting to a diverse range of environments. Their remarkable ability to photosynthesize and make their own food, as well as their adaptability across a variety of habitats, make.....»»
"e-Drive": New gene drive reverses insecticide resistance in pests... then disappears
Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ineffective......»»
Earliest fish-trapping facility in Central America discovered in Maya lowlands
An archaeologist from the University of New Hampshire and her team have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland we.....»»
Niagara fireball event leads to discovery of tiniest known asteroid
In an international study led by Western University and Lowell Observatory, scientists describe a pioneering, integrative approach for studying near-Earth asteroids based largely on a November 2022 fireball event that dropped meteorites in the Niagar.....»»
Improved ultrasound technique produces previously unattainable images inside live cells
A ultrasound technique from the University of Nottingham will allow the production of sharper images inside live cells without causing damage at resolutions that were previously unattainable......»»
Researchers develop miRNA-tunable living interface for neurovascular remodeling
A research team led by Dr. Du Xuemin from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has reported a living interface with unique functionalities of durable secretion of bioactive exosomes with tunable con.....»»
