Scientists have seen one of the mysterious “dark spots” on Neptune from Earth for the first ever time. Researchers spotted the feature using the European Southern Observatory’s Very Large Telescope, or VLT. Using that telescope, astronomers were able to examine a large dark spot – which was joined by a smaller, bright spot, they said, of a kind that has never seen before. Scientists still do not know why those spots form on Neptune’s blue atmosphere. But they hope that the new observations could help answer questions about their origin. “Since the first discovery of a dark spot, I’ve always wondered what these short-lived and elusive dark features are,” said Patrick Irwin, professor at the University of Oxford and lead investigator of the study. It has already helped rule out one possibility: that the dark spots are caused when the clouds on the planet clear. The observations instead suggest that the spot is formed when air particles make a layer below the main one go darker, caused by ice and haze mixing in the atmosphere. Understanding the spots has been difficult because they leave the planet’s surface as mysteriously as they arise. They have also been difficult for researchers to actually examine, given the difficulty of spotting them through telescopes. Previously, scientists were forced to send spacecraft to see the spots, and the first was observed in 1989, when Nasa’s Voyager 2 flew past. It disappeared a few years later. In recent years, scientists have been able to examine them with the Hubble Space Telescope, which has seen more spots on the atmosphere. When it did so, astronomers were able to point ground-based telescopes towards them, allowing for more detailed research. “This is an astounding increase in humanity’s ability to observe the cosmos,” said Michael Wong, a researcher at the University of California, Berkeley and a co-author on the paper. “At first, we could only detect these spots by sending a spacecraft there, like Voyager. “Then we gained the ability to make them out remotely with Hubble. Finally, technology has advanced to enable this from the ground.” The new observations allowed scientists to examine the spot using the VLT’s Multi Unit Spectroscopic Explorer, which let them split the light from Neptune and the spot into its component colours. That in turn means that astronomers can understand the height at which the spot sits, and how the atmosphere is composed. As well as helping examine the dark spots, scientists also saw a surprise result: another, entirely new kind of bright spot. “In the process we discovered a rare deep bright cloud type that had never been identified before, even from space,” said Wong. The work is described in a new paper, ‘Cloud structure of dark spots and storms in Neptune’s atmosphere’, published in Nature Astronomy.

Bad news for milk tea drinkers, as the beverage - which comes in different forms such as bubble tea - has some disturbing links to depression, according to a new study. Milk tea is widely consumed worldwide, but it has become particularly popular among young people in China over recent years. While many of us buy the drink as a sweet treat or pick-me-up, researchers from Tsinghua University and the Central University of Finance and Economics in China investigated whether milk tea addiction is a thing. After 5,281 university students in Beijing were surveyed as part of the research published in the Journal of Affective Disorders, they found that milk tea addiction does exist and also spotted connections between this issue with anxiety and depression. Researchers noted the "tremendous growth" the beverage has had with youth as well as their findings from the study. "Our findings highlighted that milk tea consumption might lead to addiction, and it is associated with depression, anxiety, and suicidal ideation," they wrote in the paper. Nearly half of the students surveyed said they had at least one cup of milk tea on a weekly basis, while a scale of addiction was used to understand the symptoms such as cravings, immoderation and how this affects daily life. Given that milk tea includes both caffeine and extra sugar, the effects of these ingredients cause worry - with low moods and social isolation as examples. "The results indicate that milk tea consumption might lead to addiction symptoms, including frequency, dependence/craving, intention to stop, unable to stop, tolerance, and guilty feelings," the paper read. Milk tea addiction has been compared to social media and drugs in terms of how damaging it can be, particularly when used to try and regulate emotions. However, a large study would be needed over a longer period of time to gain further understanding of this. To conclude, researchers want further regulation and safeguarding against both the physical and mental symptoms possibly connected to drinking milk tea, for example addiction, depression and obesity. "Current findings can assist policymakers in developing regulations such as restricting advertising, providing psycho-education, establishing food hygiene standards for such a prosperous youth-dominant consumption industry while protecting their mental health," they stated.

Security researchers have discovered a USB propagating “worm” developed by state-backed Russian hackers to infect Ukrainian targets, which they warn is now spreading globally. The LitterDrifter worm automatically spreads malware via a hidden file within USB drives, with a victim’s data then transmitted back to the attackers. Cyber security firm Check Point Software described the malware as “a unique player in the Russian espionage ecosystem”, designed to collect data and spy on communications. The method of its distribution via removable USB drives means it is difficult to contain the worm to just the intended targets, according to the researchers. “Due to the nature of the USB worm, we see indications of possible infection in various countries like the US, Vietnam, Chile, Poland and Germany,” Check Point researchers wrote in a blog post detailing the threat. “In addition, we’ve observed evidence of infections in Hong Kong. All this might indicate that much like other USB worms, LitterDrifter have spread beyond its intended targets.” The Security Service of Ukraine (SSU) said the campaign had been identified as originating from personnel within Russia’s Federal Security Service (FSB). Since Russia’s invasion of Ukraine last year, the Ukrainian government has been under “near-constant digital attack”, according to Google’s Shane Huntley, who is a senior director at the tech giant’s threat analysis group. “Russian government-backed attackers have engaged in an aggressive, multi-pronged effort to gain a decisive wartime advantage in cyberspace, often with mixed results,” Mr Huntley wrote in a July post. Cyber attacks have also been perpetrated against Nato partners and Ukraine’s allies, witch such attacks increasing in 2023. Ukraine’s National Cybersecurity Coordination Center (NCSCC) recently revealed that Russian-backed hackers have been targeting European embassies. The latest discovery demonstrates how targeted attacks can easily spread globally when distributed in such a manner. “It leverages simple, yet effective techniques to ensure it can reach the widest possible set of targets in the region,” the Check Point researchers noted. “It’s clear that LitterDrifter was designed to support a large-scale collection operation.” Read More Tiny solar-powered van unveiled in Japan Democrats accuse Elon Musk and X of profiting from Hamas propaganda OpenAI reaches deal with Sam Altman to return as chief executive Tiny solar-powered van unveiled in Japan Democrats accuse Elon Musk and X of profiting from Hamas propaganda OpenAI reaches deal with Sam Altman to return as chief executive
