Most massive galaxies stopped producing stars very early on in their lives—scientists find out why
Publicado em 29 de maio de 2026
Astronomers have observed that the most massive galaxies stopped producing stars early on in cosmic history, roughly one billion years after their formation. This has proved to be quite baffling for the community. After all, our galaxy, the Milky Way, which is as old as the universe itself, is still producing stars 13.5 billion years after its formation, albeit at a slow rate. Aiming to unravel the mystery, researchers at the Institute of Astronomy, Geophysics, and Atmospheric Sciences at the [...]

Why the most massive galaxies in the early universe stopped forming stars prematurely
Publicado em 28 maio 2026Astronomical observations show that the most massive galaxies in the early universe formed approximately three to four billion years after the Big Bang and stopped producing stars very early in cosmic history, around one billion years after their formation. This strange behavior has puzzled experts in the field. For comparison, our galaxy, the Milky Way, is as old as the universe itself and continues to produce stars, albeit at a low rate, even 13.5 billion years after its formation. A study [...]ver notícia -
How a father's obesity affects his children's metabolism
Publicado em 22 maio 2026The scientific literature already contains robust evidence that obesity, whether maternal or paternal, can lead to metabolic changes in offspring that increase their risk of developing diseases. A new study published in the journal Nature Communications reveals the mechanism by which this "inheritance" is transmitted to the embryo by the father via the sperm. In experiments with mice, the authors observed that the offspring of obese males were born at a normal weight. However, as the [...]ver notícia -
Scientist have found a new cheap route to the Moon—and it could have solved a major Artemis II issue
Publicado em 21 maio 2026It's no secret that space missions are expensive. That is why scientists and researchers rack their brains trying to figure out the most efficient path between celestial bodies. And now, an international team of researchers claims to have found a new method of charting a more efficient route between Earth and the Moon. According to the latest study published in the journal Astrodynamics on April 10, 2026, the researchers did this by using advanced computer modeling. Based on the [...]ver notícia -
Scientists find record-efficient Earth–moon travel route
Publicado em 19 maio 2026Fuel-saving discovery: A new Earth–moon route cuts fuel needs by 58.80 m/s, reducing mission costs and enabling greater payload capacity. Counterintuitive path: The most efficient trajectory involves a close lunar flyby before entering the L1 Lagrange point from the far side. Navigation potential: This route could integrate with future lunar navigation tools, like ultrastable lasers proposed for the moon’s polar craters. Record efficiency in Earth–moon travel Gravity-assisted [...]ver notícia -
Creatine improves physical performance but does not necessarily reduce inflammation, finds study
Publicado em 18 maio 2026Creatine, one of the most popular supplements among gym-goers and athletes, does not appear to have the anti-inflammatory effect that many imagine. This conclusion comes from a systematic review and meta-analysis conducted in Brazil by researchers at São Paulo State University (UNESP), which evaluated clinical trials in humans. The study indicates that, to date, there is no consistent evidence that creatine reduces inflammatory markers in the body. The study was conducted at UNESP's [...]ver notícia -
Mathematical method calculates most efficient Earth-moon route yet
Publicado em 15 maio 2026Trajectory of the complete journey between the Earth and Moon orbits. Credit: Allan Kardec de Almeida Júnior et al./Astrodynamics Researchers have developed a mathematical method that enables more precise calculations of the most economical travel routes between the orbits of celestial bodies. To demonstrate this method, they calculated a more efficient path between Earth's and the moon's orbits than any previously described in the scientific literature. The study is published in [...]ver notícia -
Scientists discover a shortcut to the moon - and it could slash the cost of future missions
Publicado em 15 maio 2026A trip to the moon might not need to break the bank, as scientists have discovered a shortcut that could slash the cost of future missions. Much like flying on a jet, one of the biggest costs associated with getting to our lunar satellite is the fuel. NASA's Space Launch System rocket uses over two million litres of propellant at an estimated cost of $4bn (£2.8bn) per launch, while the Orion spacecraft needs yet more to navigate to the lunar surface. However, scientists have now [...]ver notícia -
Even at low concentrations, fine particle pollution is tied to increased hospitalizations for kidney disease
Publicado em 14 maio 2026A study published in the journal Scientific Reports has shown a strong correlation between the concentration of particulate matter in the air of São Paulo, Brazil—primarily emitted by vehicle fuel combustion—and kidney disease. The study estimated the risk of hospitalization for three kidney conditions based on the levels of this type of air pollution from 2011 to 2021. Men across different age groups were found to be at the highest risk of hospitalization. Exposure to even low [...]ver notícia -
New fossils could rewrite the origin story of complex animal life on Earth, study says
Publicado em 14 maio 2026Scientists say they may have found an important clue to the early history of animal life on Earth. In rocks from the Tamengo Formation in the Brazilian state of Mato Grosso do Sul, features once read as tiny animal trails now look more like preserved clusters of bacteria and algae. The team of researchers studying Ediacaran microfossils from Brazil published their findings in the journal Gondwana Research. The study used high-resolution imaging and chemical analysis to reexamine fossils [...]ver notícia
