Bacterial genome is regulated by an ancient molecule
We are all collections of cells, each cell containing the instructions—our DNA—to become any other cell. What differentiates a heart cell from a skin cell from a brain cell is the expression—or silencing—of genes......»»
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.....»»
Scientists reveal transport mechanism of norepinephrine transporter and binding mode of small molecule and peptide drugs
Noradrenaline (NA) is an important monoamine neurotransmitter in the nervous system. The noradrenaline transporter (NET) located on the presynaptic membrane can transport NA into presynaptic neurons......»»
"Screaming Woman" mummy may have died in agony 3,500 years ago
In 1935, the Metropolitan Museum of New York led an archaeological expedition to Egypt. In Deir Elbahari near Luxor, the site of ancient Thebes, they excavated the tomb of Senmut, the architect and overseer of royal works—and reputedly, lover—of.....»»
Plant biologists discover an ancient gene family is responsible for plant prickles across species
According to Greek mythology, red roses first appeared when Aphrodite pricked her foot on a thorn, spilling blood on a white rose. Since then, roses' thorns have captured the imaginations of countless poets and forlorn lovers......»»
Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides
Plant diseases pose significant challenges to agricultural productivity, presenting formidable hurdles that require urgent attention. Left unchecked, these diseases can spread rapidly, inflicting widespread damage on crops and leading to reduced yiel.....»»
New evidence of Neolithic occupations in the Aragonese site of Huerto Raso
Researchers from the UAB and the University of Zaragoza who have carried out the first extensive excavation campaign of the Huerto Raso site (Huesca) have made new discoveries that reinforce the hypothesis of its occupation during the ancient Neolith.....»»
New perspectives for using corals in climate research
Ancient ocean temperatures are most commonly reconstructed by analyzing the ratio of different oxygen atoms in the calcium carbonate remains of fossils. However, this presents many challenges, including a combination of biological processes known as.....»»
How duplicated genomes helped grasses diversify and thrive
Grasses cover about 40% of the Earth's land surface, thriving in a multitude of environments. The evolutionary success of this plant family, which includes rice, maize, wheat and bamboo, likely results from a history of whole-genome duplications, acc.....»»
Elusive predicted water structure created in the laboratory
Clathrate hydrates are complex water structures that contain foreign guest molecules inside a host water-molecule shell. A predicted clathrate hydrate phase structure has been stably synthesized in the lab and may play an important role in future mat.....»»
Researchers identify unique phenomenon in Kagome metal
In traditional Japanese basket-weaving, the ancient "Kagome" design seen in many handcrafted creations is characterized by a symmetrical pattern of interlaced triangles with shared corners. In quantum physics, the Kagome name has been borrowed by sci.....»»
New derivative from long pepper shows promise against antibiotic resistance
Antibiotic resistant bacterial pathogens are on the rise, while fewer antibiotics are being developed. Prof. Ariel Kushmaro and his local and international colleagues tackled the need by focusing on the long pepper. Known in traditional medicine for.....»»
How bacteria attach their cloaks of invisibility to immune defenses
Bacteria have different strategies for protecting themselves. Some bacterial pathogens surround themselves with a shell made of many sugar chains that lie close together, also known as capsular polymers. This protects the bacteria from drying out and.....»»
Scientists now know when an ancient lake supported human life in the Namib Sand Sea
Desert regions in northern Africa and the Arabian Peninsula have been well studied by archaeologists as the home of early humans and as routes of migration along "green corridors.".....»»
Has NASA found evidence of ancient life of Mars? An expert examines the latest discovery
NASA has announced the first detection of possible biosignatures in a rock on the surface of Mars. The rock contains the first martian organic matter to be detected by the Perseverance rover, as well as curious discolored spots that could indicate th.....»»
Avocado genome assembled: Uncovering disease resistance and fatty acid secrets
The avocado, celebrated for its nutritious unsaturated fats and distinctive flavor, encounters notable agricultural challenges, particularly its vulnerability to diseases that can drastically reduce fruit quality and yield......»»
Researchers use omics technologies to accelerate yam research progress
A research team has summarized current progress on the yam genome, plastome, transcriptome, proteome, and metabolome, highlighting the nutrient-rich and bioactive compound-laden Dioscorea species. This research holds significant value for genetic stu.....»»
The hidden drivers of evolution: Transposable elements in Rosaceae genomes
Transposable elements are mobile DNA sequences that play a crucial role in plant genome architecture and gene regulation. They drive genome size variation and affect gene expression by altering regulatory networks. Despite their significance, the div.....»»
New and improved drug-delivery molecules for skeletal muscle
Researchers from Tokyo Metropolitan University have created a new drug-delivery molecule, a zwitterionic polymer complex that can help get plasmid DNA inside cells when injected into skeletal muscle, a crucial step in the expression of therapeutic RN.....»»
NASA Mars rover captures rock that could hold fossilized microbes
