Record number of Asian hornets trapped in Alderney
A record number of Asian hornets have been trapped in Alderney, a volunteer group has said.
Alderney Asian Hornet Group said 365 Asian hornet queens had been caught in traps and three primary nests destroyed, a significant increase on previous years that experts have attributed to warm spring temperatures and consistent easterly winds in the Channel Islands.
In 2024 a total of 99 queens were trapped and 26 in 2023, said the group.
The first Asian hornet, an invasive species which feeds on native bees and wasps, was found in Alderney in 2016.

David Jarolík, the group's administrator, asked volunteers to now remove the Asian hornet traps to avoid catching other insects.
He urged them to look for secondary nests which the hornets would now be forming.
"The possibility of discovering secondary nests is practically island-wide," he said.
He thanked volunteers for their support and asked islanders to send a photo and details to the group if they suspected they had found an Asian hornet or nest.

A radio signal from the beginning of the universe could reveal how everything began
A radio signal from the early universe could allow us to understand how everything that surrounds us began. The signal – known as the 21-centimetre signal – could finally let us understand how the first stars and galaxies switched on, and brought the universe from darkness to light. 'This is a unique opportunity to learn how the universe's first light emerged from the darkness,' said co-author Anastasia Fialkov from Cambridge University, in a statement. 'The transition from a cold, dark universe to one filled with stars is a story we're only beginning to understand.' The signal comes to us from more than 13 billion years ago, just a hundred million years after the Big Bang. The faint glow is created by hydrogen atoms that fill up the space between regions of space where stars are being formed. Scientists now believe they will be able to use the nature of that signal to better understand the early universe. They will do that with a radio antenna called REACH – the Radio Experiment for the Analysis of Cosmic Hydrogen – which will try and capture radio signals to reveal data about the beginnings of the universe. To better understand how that project might work, researchers created a model that predicted how REACH as well as another project called the Square Kilometre Array will be able to provide information about the masses and other details of the first stars. 'We are the first group to consistently model the dependence of the 21-centimetre signal of the masses of the first stars, including the impact of ultraviolet starlight and X-ray emissions from X-ray binaries produced when the first stars die,' said Professor Fialkov. 'These insights are derived from simulations that integrate the primordial conditions of the universe, such as the hydrogen-helium composition produced by the Big Bang.' 'The predictions we are reporting have huge implications for our understanding of the nature of the very first stars in the Universe,' said co-author Eloy de Lera Acedo, Principal Investigator of the REACH telescope. 'We show evidence that our radio telescopes can tell us details about the mass of those first stars and how these early lights may have been very different from today's stars. 'Radio telescopes like REACH are promising to unlock the mysteries of the infant Universe, and these predictions are essential to guide the radio observations we are doing from the Karoo, in South Africa.' The work is described in a new paper, 'Determination of the mass distribution of the first stars from the 21-cm signal', published in the journal Nature Astronomy.

Scientists Beamed Light Right Through a Man's Head For The First Time
Scientists have developed a new technique for non-invasive brain imaging – and it involves shining light all the way through the head, from one side to the other. Currently the best portable, low-cost method for monitoring the brain is functional near-infrared spectroscopy (fNIRS). Unfortunately, this can only penetrate a few centimeters down, meaning bigger, bulkier MRI machines are needed to probe deeper layers of the brain. A new method, developed by a team from the University of Glasgow in Scotland, expands the sensitivity of fNIRS to shine light all the way through the complex combinations of bone, neurons, and tissue that make up our heads. Doing so required a few tweaks: the researchers increased the strength of the near-infrared laser (within safe boundaries, of course), while also putting in place a more comprehensive collection setup. Even with these adjustments, only a small trickle of photons made it from one side of the head to the other during experiments. However, it's a promising start for portable imaging methods that go deeper, giving us crucial insight into what's happening inside our skulls without opening them up. "These findings uncover the potential to extend non-invasive light based on brain imaging technologies to the tomography of critical biomarkers deep in the adult human head," write the researchers in their published paper. There are quite a number of caveats to mention here. The process was only successful with one out of eight study participants: a man with fair skin and no hair on his head. It needs a very specific setup, and an extended scanning time – around 30 minutes. Those limitations are all acknowledged by the researchers, but they sacrificed certain variables (such as speed) to try and prove that it was possible to get light all the way through a human head via fNIRS – and they succeeded. Computer models based on detailed 3D head scans were used to predict the movement of photons through the skull. These matched up closely with the actual light collected, adding further credibility to the results. What's more, the research also found that light didn't scatter at random through the head, but rather followed preferred paths – including through parts that were more transparent, like those filled with cerebrospinal fluid. That knowledge could help brain scans be better targeted in the future. "Different source positions on the head can then selectively isolate and probe deep regions of the brain," write the researchers. The advantages of fNIRS are that it's a relatively inexpensive and compact technology. Imagine scans for strokes, brain injuries, and tumors that are more accessible for a wider range of people. As future imaging devices are developed, this research should prove useful for techniques that go deeper into the brain – even if it might be a while before we can get light through the entire head in a timeframe that's practically useful. We know that brain scans have tremendous value in everything from understanding adolescence in youngsters to treating disease towards the end of our lives, so there's a huge amount of potential here. "Optical modalities for noninvasive imaging of the human brain hold promise to fill the technology gap between cheap and portable devices such as electroencephalography (EEG) and expensive high-resolution instruments such as functional magnetic resonance imaging (fMRI)," write the researchers. The research has been published in Neurophotonics.

Scientists Working to Decode Signal From Earliest Years of Universe
As mysterious as the Big Bang that gave birth to the universe is the brief but tumultuous period that immediately followed it. How did the cosmos transform from a uniform sea of darkness into a chaotic swirl brimming with radiant stars? What were these first stars like, and how were they born? So far, we have very strong suspicions, but no hard answers. One reason is that the light from this period, called the cosmic dawn, is extremely faint, making it nearly impossible to infer the traits of these first cosmic objects, let alone directly observe them. But that's about to change, according to a team of international astronomers. In a new study published in the journal Nature Astronomy, the astronomers argue that we're on the verge of finally decoding a radio signal that was emitted just one hundred millions years after the Big Bang. Known as the 21 centimeter signal, which refers to its distinct wavelength, this burst of radiation was unleashed as the inchoate cosmos spawned the earliest stars and black holes. "This is a unique opportunity to learn how the universe's first light emerged from the darkness," said study co-author Anastasia Fialkov, an astronomer from the University of Cambridge in a statement about the work. "The transition from a cold, dark universe to one filled with stars is a story we're only beginning to understand." After several hundred thousand years of cooling following the Big Bang, the first atoms to form in the universe were overwhelmingly neutral hydrogen atoms made of one positively charged proton and one negatively charged electron. But the formation of the first stars unbalanced that. As these cosmic reactors came online, they radiated light energetic enough to reionize this preponderance of neutral hydrogen atoms. In the process, they emitted photons that produced light in the telltale 21 centimeter wavelength, making it an unmistakeable marker of when the first cosmic structures formed. Deciphering these emissions would be tantamount to obtaining a skeleton key to the dawn of the universe. And drum roll, please: employing the Radio Experiment for the Analysis of Cosmic Hydrogen telescope, which is currently undergoing calibration, and the enormous Square Kilometer Array, which is under construction Australia, the researchers say they've developed a model that can tease out the masses of the first stars, sometimes dubbed Population III stars, that are locked inside the 21 centimeter signal. While developing the model, their key revelation was that, until now, astronomers weren't properly accounting for the impact of star systems called x-ray binaries among these first stars. These are systems where a black hole or neutron star is stripping material off a more ordinary star that's orbiting it, producing light in the x-ray spectrum. In short, it appears that x-ray binaries are both brighter and more numerous than what was previously thought. "We are the first group to consistently model the dependence of the 21-centimeter signal of the masses of the first stars, including the impact of ultraviolet starlight and X-ray emissions from X-ray binaries produced when the first stars die," said Fialkov. "These insights are derived from simulations that integrate the primordial conditions of the universe, such as the hydrogen-helium composition produced by the Big Bang." All told, it's another promising leap forward in the field of radio astronomy, where recent advances have begun to reveal an entire "low surface brightness" universe — and a potentially profound one as well, with the promise to illuminate our understanding of the cosmic dawn as never never before. "The predictions we are reporting have huge implications for our understanding of the nature of the very first stars in the universe," said co-author Eloy de Lera Acedo, a Cambridge astronomer and a principal investigator of the REACH telescope. "We show evidence that our radio telescopes can tell us details about the mass of those first stars and how these early lights may have been very different from today's stars."
