The formation of gap solitons in a 1D dissipative topological lattice
Topological photonics is a rapidly evolving area of research that focuses on the design of photonic lattices where the behavior of light is inspired from the physics of topological insulators. While most studies in this area presented photonic systems with linear topological properties, recent works have started paving the foundations of non-linear topological photonics.
The signaling pathways that make plants more resistant to flooding
Extreme weather phenomena are on the rise worldwide, including frequent droughts and fires. Floods are also a clear consequence of climate change. For agriculture, a flooded field means major losses: about 15% of global crop losses are due to flooding.
Digging is not just a game for children in hunter-gatherer groups
Ana Mateos and Jesús Rodríguez, scientists at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have published an experimental energy study in the journal Human Nature, using volunteers of both sexes aged 8 to 14, showing that digging is an activity requiring major physical effort at these ages, although it is not excessive. This effort of digging and extracting...

Comet Interceptor approved for construction
ESA's Comet Interceptor mission to visit a pristine comet or other interstellar object just starting its journey into the inner solar system has been "adopted" this week; the study phase is complete and, following selection of the spacecraft prime contractor, work will soon begin to build the mission.
Why do students with disability go to 'special schools' when research tells us they do better in the mainstream system?
This week, the disability royal commission is looking atthe experiences of children and young people with disability in different schools across Australia. This includes mainstream schools as well as so-called "special schools."
What ancient toilets can teach us about Maya life, and tamales
Ancient toilets and trash pits are like heaven to archaeologists. They might not have the glamor of a gleaming medieval jewel or intricate Roman mosaic, but they brim with clues about the everyday life of bygone civilizations: the detritus—and discharges—of our ancestors telling rich stories of what the past was like for those without palaces or chests of gold. From the mundane and the messy,...
New map shows seabed of the Southern Ocean in unprecedented detail
The features of the ocean floor help determine how water masses and ocean currents move and how they affect our climate. Biodiversity is also influenced by seafloor landforms. Accordingly, having as precise information on the seafloor topography as possible is indispensable for oceanographic and climate research. With the second version of the International Bathymetric Chart of the Southern Ocean...
The physicochemical nature of colloidal motion waves among silver colloids
Traveling waves are commonly observed in biological and synthetic systems, and recent discoveries have shown how silver colloids form traveling motion waves in hydrogen peroxide under UV light. In a new report now published in Science Advances, Xi Chen and a team of researchers in smart materials, physics and optics at the Harbin Institute of Technology, and the Shanghai Jiao Tang University, in...
NASA has purchased five more Crew Dragon missions, keeping the ISS going until 2030
On November 15th, 2020, NASA and SpaceX made history when a crewed spacecraft—the Crew Dragon Resilience—lifted off from American soil and delivered four astronauts to the International Space Station (ISS). This mission (designated Crew-1) was a culminating achievement for NASA's Commercial Crew Program (CCP) and effectively restored domestic launch capability to the U.S. for the first time...
Extreme, severe drought impacting the upper Colorado River basin in the second century, new study finds
- ScienceDaily
- 22/6/9 16:01
The Colorado River is in an extremely severe drought and has been for the last 22 years. To better understand this drought, researchers looked at the drought history within the Colorado River Basin. Previous studies have gone back 1,200 years, but this paper goes back 2,000 years. The findings, using paleo hydrology, show that there was an even more severe drought in the Colorado River Basin in...
New research shows climate change impacts on whale habitat use in the warming Gulf of Maine
- ScienceDaily
- 22/6/9 16:00
New research finds climate change is having an impact on how large whale species, including the critically endangered North Atlantic right whale, use habitats in the warming Gulf of Maine, showing that right whales' use of Cape Cod Bay has shifted significantly over the last 20 years.
Newly discovered molecular network regulates vitamin C biosynthesis in kiwifruit
Actinidia (kiwifruit) is rich in ascorbic acid (AsA) and Vitamin C (Vc) and is known as the "King of Vc," which makes it very popular with consumers. Interestingly, the fruit AsA content of different kiwifruit species varies up to 300- to 400-fold. However, the molecular regulation mechanisms of AsA synthesis in kiwifruit are still poorly understood.
Video: Charting sea level from space
Satellite images of our planet have become essential to our survival, offering a new outlook of our world. With rising seas being one of the biggest threats to society, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.
Bones found on Isle of Wight may be from Europe’s biggest predator dinosaur
Remains suggest spinosaur, a crocodile-faced hunter, measured over 10 metres from snout to tailFossil hunters on the Isle of Wight have unearthed the remains of what may be the largest predatory dinosaur ever found in Europe.Pieces of bone belonging to a massive spinosaur, a two-legged crocodile-faced beast that lived 125m years ago, suggest the land-based hunter measured more than 10 metres from...

Diversity messages may backfire when companies focus on diversity's benefits for the bottom line
Companies that justify their diversity efforts by saying that a diverse workforce will improve their bottom line risk alienating the diverse employees that they hope to attract, according to research published by the American Psychological Association.
New species of alga named for poet Amanda Gorman
- ScienceDaily
- 22/6/9 14:45
Researchers discovered a new species of alga in central New York and named it Gormaniella terricola, with the genus named after poet Amanda Gorman. The new species is quite interesting in that its chloroplast genome is highly repetitive and contains quite a bit of DNA from fungi and bacteria, meaning it was likely invaded multiple times from other species through a process called horizontal...
