The earliest animal likely used chemical signaling to evolve from a single cell to a multicellular organism, according to a study led by an Indiana University Bloomington scientist. The findings provide new information about how one of the biggest tr.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Q&A: How animal tracking data can help preserve biodiversity
Today's ecologists have more data than ever before to help monitor and understand the world's biodiversity. Yet researchers are still working to get more detailed information to better combat declining animal populations that can eventually lead to s.....»»
New plant bug species discovered in French Polynesia
Seventeen new species of plant bugs—a group of insects with a strawlike mouth used to feed on plant and animal matter—have been identified on the islands of French Polynesia, and their names honor scientists, actors, and Vice President Kamala Har.....»»
Researchers uncover focal adhesions as subcellular signaling hubs in PI3K-AKT pathway
The phosphatidylinositol 3-kinase (PI3K)-AKT signaling pathway is one of the most critical and extensively investigated signaling pathways. It is the central regulator of various cellular processes including cell growth, proliferation, metabolism, an.....»»
Researchers discover localized pain relief using known chemical reaction
A team of international researchers including those from the University of Adelaide have taken a well-known chemical reaction as the basis of a new generation of targeted pain relief medication......»»
Scientists identify chemical properties of superheavy elements moscovium and nihonium
An international team led by scientists of GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz and the Helmholtz Institute Mainz, succeeded in determining the chemical properties of the artificially produced superheavy elements moscovium and n.....»»
Organosilicon chemistry offers options for replacing PFAS in food and medical industries
Due to the unique properties of PFAS, almost no other chemical substances can compete with them. That explains why it is so hard to find a replacement for these toxic "forever chemicals," which accumulate in the environment and do not break down over.....»»
Rubber plantations increase leaching of dissolved organic carbon in soil, study finds
Rubber planting brings huge economic benefits, but large-scale rubber plantations have a great impact on the ecological environment, especially in terms of the soil's physical and chemical properties......»»
Only 3% of South Africans can name all five national animals and plants. Why these symbols matter
Alongside a national flag, anthem and coat of arms, most countries have one or more plant and animal species that they designate as national symbols. The national animal of China, for example, is the giant panda, a nation-wide source of pride and dip.....»»
A physicist and his cat "reveal" the equation of cat motion
In the social media age, there is little doubt about who is the star of the animal kingdom. Cats rule the screens just as their cousins, the lions, rule the savanna. Thanks to Erwin Schrödinger, this feline also has a place of honor in the history o.....»»
Fossil of huge terror bird offers new information about wildlife in South America 12 million years ago
Researchers including a Johns Hopkins University evolutionary biologist report they have analyzed a fossil of an extinct giant meat-eating bird—which they say could be the largest known member of its kind—providing new information about animal li.....»»
Not too big, not too small: Why modern humans are the ideal size for speed
The fastest animal on land is the cheetah, capable of reaching top speeds of 104 kilometers per hour. In the water, the fastest animals are yellowfin tuna and wahoo, which can reach speeds of 75 and 77 km per hour respectively. In the air, the title.....»»
As hospitals struggle with IV fluid shortage, NC plant restarts production
The initial batches will be shipped in late November at the earliest. The western North Carolina plant that makes 60 percent of the country's intravenous fluid supply has restart.....»»
Computational model calculates an organism"s ideal learning rate based on its life cycle and surroundings
Researchers at the Complexity Science Hub and Santa Fe Institute have developed a model to calculate how quickly or slowly an organism should ideally learn in its surroundings. An organism's ideal learning rate depends on the pace of environmental ch.....»»
AI method captures ecotourism photos to monitor remote animal species
A team of computer scientists, ecologists and statisticians at Stony Brook University, working with a colleague from the U.S. Geological Survey, has found that it is possible to use AI applications to find images captured by ecotourists for use in st.....»»
Accelerating 3D nanofabrication using a sensitive cationic photoresist
Two-photon laser direct writing lithography or TPL is a cutting-edge technique used for creating nanoscale structures. It works by leveraging specific materials known as photoresists, which change their chemical properties when exposed to light. Thes.....»»
Amid controversial changes, Reddit is getting more popular—and profitable
With Reddit finally making money, the Reddit of yesteryear isn't coming back. In May 2023, Reddit announced that its API would no longer be free, signaling the demise of most thi.....»»
How researchers can maximize biological insights using animal-tracking devices
Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell a deeper story about the lives of.....»»
Solar-powered animal cells: Combining chloroplasts from algae with hamster cells
Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in.....»»
