Some scientists propose that in the beginning, geochemistry gave way to biochemistry — with no genetic material necessary. Only later did RNA and DNA appear.
How dangerous is it? Where did it come from? H5N1 influenza’s origins stretch back to the 1990s, and key events paved the way for the outbreak we’re seeing today.
The mycorrhizae that live among and in plant roots can boost the health of certain species, and even whole ecosystems — but scientists warn against a one-size-fits-all approach
Scientists are seeing signs of resistance to the infections that have been wiping out the world’s amphibian populations — and developing strategies to aid in the fight Down Under
To understand the origins of multicelled life, researchers are studying a motley assortment of simpler animal relatives. The commonalities they’re unearthing offer a trove of clues about our mutual past.
With the first medical therapy approved and systems like CRISPR-Cas showing up in complex cells, there’s a lot going on in the genome editing field. Here’s our primer.
Growing evidence suggests a link between the debilitating neurological illness and the microbes that live in our intestines. The vagus nerve may be a pathway.
New research suggests that to maintain a healthy brain, we should tend our gut microbiome. The best way to do that right now is not through pills and supplements, but better food.
A scientist whose work was key to identifying, studying and finding treatments for this life-threatening virus discusses the scientific journey and challenges that persist
Scientists agree that eons ago, a bacterium took up residence inside another cell and became its powerhouse, the mitochondrion. But there are competing theories about the birth of other organelles such as the nucleus and endoplasmic reticulum.
Scientists are scouring garbage sites around the world for bacteria, fungi and even insects that harbor enzymes that could be harnessed for breaking down various polymers. It’s early days, but if the efforts can be efficiently scaled-up, such biological recycling could put a dent in the plastic waste problem.
Clear Lake, the state’s largest freshwater body of water, is fouled each year by algal blooms, one of many assaults endured by the battered ecosystem. Can a multipronged plan help it recover?
