Scientists discover ‘lost world’ of early ancestors in billion-year-old rocks
2023-06-07
The discovery of a “lost world” of ancient organisms that lived in Earth’s waterways at least 1.6 billion years ago could change our understanding of our earliest ancestors.
Known as the ‘Protosterol Biota’, these microscopic creatures are part of a family of organisms called eukaryotes. Eukaryotes have a complex cell structure that includes mitochondria, known as the “powerhouse” of the cell, and a nucleus that acts as the “control and information centre”. ...
Remains of an extinct world of organisms discovered
2023-06-07
Newly discovered biomarker signatures point to a whole range of previously unknown organisms that dominated complex life on Earth about a billion years ago. They differed from complex eukaryotic life as we know it, such as animals, plants and algae in their cell structure and likely metabolism, which was adapted to a world that had far less oxygen in the atmosphere than today. An international team of researchers, including GFZ geochemist Christian Hallmann, now reports on this breakthrough for the field of evolutionary geobiology in the journal Nature.
The previously unknown “protosteroids” were ...
Scientists discover ‘lost world’ of our early ancestors in billion-year-old rocks
2023-06-07
The newly discovered record of so-called protosteroids was shown to be surprisingly abundant throughout Earth´s Middle Ages. The primordial molecules were produced at an earlier stage of eukaryotic complexity – extending the current record of fossil steroids beyond 800 and up to 1600 million years ago. Eukaryotes is the term for a kingdom of life including all animals, plants and algae and set apart from bacteria by having a complex cell structure that includes a nucleus, as well as a more complex molecular machinery. “The highlight of ...

New study identifies mechanism driving the sun’s fast wind
2023-06-07
The fastest winds ever recorded on Earth reached more than 200 miles per hour, but even those gusts pale in comparison to the sun’s wind.
In a paper published June 7, 2023 in the journal Nature, a team of researchers used data from NASA’s Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released from the magnetic field near the sun’s surface is powerful enough to drive the fast solar wind, which is made up of ...
Pre-basophils: A basophil origin story
2023-06-07
Researchers from Tokyo Medical and Dental University (TMDU) find that pre-basophil and mast cell progenitors differentiate into pre-basophils before producing mature basophils in mice
Tokyo, Japan – Big changes often happen in small steps, and it’s not always easy to see how we get from point A to point B. Now, researchers from Japan have found a new step in the process of cell differentiation that leads to the production of fully functional basophils, which are critical cells in the immune system.
In a study published this month in Nature Communications, researchers from Tokyo Medical and Dental University (TMDU) have revealed a previously unknown intermediate ...

Leading plant science journal publishes a special issue on key discoveries in plant pathology
2023-06-07
In just 7 years, the Irish Potato Famine caused approximately one million people to starve to death and forced another estimated million to flee Ireland as refugees. A mold called Phytophthora infestans infected Ireland’s potato crop, a staple food, and spread rapidly throughout the island. The seemingly tiny fungus destroyed roughly 75% of potato crops over the duration of the great hunger. This catastrophic famine, along with several others in various parts of the world throughout history, highlighted the critical need for the study of plant diseases.

Remnants of ancient virus may fuel ALS in people
2023-06-07
More than 5,000 people are diagnosed annually with ALS (amyotrophic lateral sclerosis), a fatal, neurodegenerative disease that attacks nerve cells in the brain and spinal cord, gradually robbing people of the ability to speak, move, eat and breathe.
To date, only a handful of drugs exist to moderately slow its progression. There is no cure.
But CU Boulder researchers have identified a surprising new player in the disease—an ancient, virus-like protein best known, paradoxically, for its essential role in enabling placental development.
The findings ...

Researchers discover chemical evidence for pair-instability supernova from a very massive first star
2023-06-07
The first stars illuminated the Universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos.
Numerical simulations of the formation of the first stars estimate that the mass of the first stars reached up to several hundred solar masses. Among them, the first stars with masses between 140 and 260 solar masses ended up as pair-instability supernovae (PISNe). PISNe are quite different from ordinary supernovae (i.e., Type II ...
