Rare Glass Blobs in Brazil Reveal an Ancient Impact, But Something Is Missing
Publicado em 06 de março de 2026
Hundreds of glass fragments found in Brazil are traces of an ancient impact that scattered them millions of years ago, scientists have found.
These blobs of material represent spray from melted rock that was liquefied in the impact, then rapidly cooled and hardened to form pebble-like glass objects, some the size of a pea and others as large as a golf ball, known as tektites.
The resulting tektite strewn field is one of only a handful discovered to date.

Genome Tweaks Drove Termite Diet Diversification
Publicado em 06 março 2026It is not always ecological conditions that determine genes, but rather genes that enable the same group of animals to occupy diverse niches, such as tree trunks and subsoil. The largest termite genome sequencing project analyzed 47 species of insects, and the initial results were published in the journal Nature Communications. The analyses revealed an expansion of genomes prior to the division of the group into wood- and soil-feeders. The addition of new genes and transposable elements [...]Mirage News (Austrália) -
Chimps love crystals and it could help explain why humans do too
Publicado em 04 março 2026Chimps’ love for crystals could help us understand our own ancestors’ fascination with these stones Ancestors of modern humans collected crystals for which they had no apparent use. A new chimp study could help researchers understand the roots of this infatuation. For hundreds of thousands of years, our hominin ancestors collected crystals. Something about these stones made them desirable, even when they weren’t used for anything. But then why collect them at all? To learn more [...]Australian Science Media Centre (Austrália) -
New Amazon Bird Species Identified by Sound, Shape
Publicado em 04 março 2026Scientists have discovered that a widely recognized Amazonian antbird is not one, but five distinct species – including two completely new to science. This revelation of hidden biodiversity was achieved by integrating artificial intelligence, vocal analysis, and traditional museum work, demonstrating how cutting-edge technology can transform our understanding of life in Earth's richest ecosystems. The study was conducted by Vagner Cavarzere and his master's student Enrico L. [...]Mirage News (Austrália) -
Lasers, Solar Slash Chemical Manufacturing Emissions
Publicado em 04 março 2026CHAMPAIGN, Ill. ― Researchers have found a way to use solar energy to power a key chemical reaction that drives many manufacturing industries. This new method can significantly reduce the energy required to run these operations, eliminate harsh oxidizing byproducts and minimize carbon emissions. Olefin epoxidation is not a process many are familiar with, but the epoxide chemicals it produces are the backbone of the textile, plastic, chemical and pharmaceutical industries. However, the [...]Mirage News (Austrália) -
Chimps' Crystal Fascination Sheds Light on Human Ancestors
Publicado em 04 março 2026Crystals have repeatedly been found at archaeological sites alongside Homo remains. Evidence shows hominins have been collecting these stones for as long as 780,000 years. Yet, we know that our ancestors did not use them as weapons, tools, or even jewelry. So why did they collect them at all? Now, in a new Frontiers in Psychology study, scientists in Spain investigated which characteristics of crystals may have made them so fascinating to our ancestors. They designed experiments with [...]Mirage News (Austrália) -
Poverty Linked to Infant Motor Delays by Six Months
Publicado em 03 março 2026Poverty can affect babies' motor development as early as six months of age. This is the conclusion of the first Brazilian study to examine the quantity and quality of motor development month by month and its relationship with socioeconomic vulnerability during the first months of life. The study, conducted by researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, followed 88 babies from three to eight months of age. Fifty of the babies were from families [...]Mirage News (Austrália) -
Poverty can affect babies’ motor development
Publicado em 03 março 2026Babies exposed to poverty show delays in motor development as early as 6 months old, but identifying risks and intervening early can reverse these effects. A Brazilian study followed 88 babies, 50 of whom from families experiencing socioeconomic vulnerability, from ages 3 to 8 months. The researchers used an approach called the “Infant Motor Profile” to assess motor development, analysing factors such as a baby’s repertoire of movement patterns, smoothness and coordination of [...]ConnectSCI (Austrália) -
Poverty linked to early motor delays in babies as young as six months

6 Million Years Ago Something Slammed Into Modern-Day Brazil
Publicado em 28 fevereiro 2026Giant impacts on Earth’s surface can be cataclysmic events with far-reaching consequences. They can excavate massive craters like the Vredefort Crater. There’s also growing evidence that impacts powerful enough can create a massive underground hydrothermal system of cracks and chemistry that could be conducive to life. These are the attention-grabbers in the world of impacts. But there are many more less energetic meteorite impacts that are more difficult to detect, and they’re [...]KSR - knowRidge Science Report (Austrália)
