Protecting coral "nurseries" is as important as safeguarding established coral reefs, new study shows
When imagining corals, the picture that comes to mind is usually a stationary one: a garden of rock-like structures covering sections of the ocean floor. Reef conservation efforts typically focus on preserving established coral and protecting them fr.....»»
Engineering stable and efficient nanosheet catalysts with Turing structures for hydrogen production
Hydrogen energy has emerged as a promising alternative to fossil fuels, offering a clean and sustainable energy source. However, the development of low-cost and efficient catalysts for hydrogen evolution reaction remains a challenge......»»
Researchers discover important membrane transport mechanism in pathogenic bacteria
Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside t.....»»
Protein structures signal fresh targets for anticancer drugs
Cell replication in our bodies is triggered by a cascade of molecular signals transmitted between proteins. Compounds that block these signals when they run amok show potential as cancer drugs......»»
Metal-organic frameworks study unravels mechanism for capturing water from air
Researchers from the Helmholtz-Zentrum Dresden-Rossendorf and Dresden University of Technology have unraveled the water adsorption mechanism in certain microporous materials—so-called hierarchical metal-organic frameworks (MOFs)—while probing the.....»»
Fossil birds: Surfaces of cervical vertebrae show conspicuous tubercles that may have served as "internal bony armor"
An international research team has examined unusual skeletal structures of various European bird fossils from the Eocene. The bone surfaces of the approximately 40- to 50-million-year-old cervical vertebrae show conspicuous tubercles, whose origin as.....»»
Australian fossil suggests photosynthesis evolved at least 1.75 billion years ago
The oldest evidence of photosynthetic structures reported to date has been identified inside a collection of 1.75-billion-year-old microfossils, a Nature paper reveals. The discovery helps to shed light on the evolution of oxygenic photosynthesis......»»
Fossil evidence of photosynthesis gets a billion years older
Remains of cells from two sites show structures similar to those in present cells. Enlarge / At left, one of the fossils, with stacks of thylakoids highlighted using yellow bars; at right, a higher magnification of the end of the.....»»
When you sit down to build a sandcastle, take a look around you: The beach is already sculpting
Arenicola, or lugworms, make some of the most beautiful structures on the beach. Little piles of wet sand are cast in a swirl from their rear end as part of their feeding cycle......»»
On-demand conformation of an artificial cytoskeleton
