Russia launches ‘massive’ attack on Ukraine’s energy infrastructure
Russia has launched a huge strike on Ukraine’s energy facilities and military infrastructure, Russian news agencies report, citing the Ministry of Defence.
Ukrainian President Volodymyr Zelenskyy on Sunday said Russian forces launched about 120 missiles and 90 drones in a “massive” combined air attack – one of the largest barrages of the near-three-year war.
A Russian drone attack on the southern Ukrainian city of Mykolaiv killed at least two people and wounded six others, including children, Zelenskyy said, adding that “all areas” were left without power.
Explosions were heard across Ukraine on Sunday, including the capital, Kyiv, the key southern port of Odesa, and the country’s west and central regions, according to local reports.

Add "Create an account" button on join-lemmy server picker page
Just noticed that unlike mastodons join page, lemmy doesn't have a "join" or "create an account" button. It'd be nice to have one, it would be more straightforward to join.
Or perhaps there is a reason why it doesn't exist?

Scientists Took Semen Onto A "Vomit Comet" Flight, And The Results Were Concerning
"Exposure to short duration gravity load changes including microgravity, as sustained in a parabolic flight statistically significantly decreases the sperm motility and vitality of human fresh sperm samples," the team found, adding that this may have huge importance for any prolonged human settlement missions in space."In the future, should humans remain in space for long periods of time with exposure to different microgravity and hypergravity peaks, which could range from months to a number of years, reproduction may pose a problem to be tackled."
The mechanism by which sperm motility was decreased remains unknown, with further study needed.

Exposure to short duration gravity load changes
Thats what the reduction in "motility and vitality" comes from. There is no way to create those conditions on the ISS so there is no point in considering the ISS for testing this.

... Why not just say that then? It would save much confusion.
It'd be hard to say whether there would be no suffering in off-world colonies, but I should doubt it. Traditionally, colonisation has been a dangerous thing, and human nature is as human nature does. The best you can do is reduce it so that what suffering does occur is either minor, or ineffectual.
Today I seem really terrible at saying what I mean! 🤣
Whether on or off planet, humans anywhere will experience suffering, likely to an extent that far outweighs the pleasure they experience. Therefore it's unethical to create more humans if your goal is reduction of suffering.

Also can we stop trying to figure out how humans are going to survive off earth... Until we at least make earth livable again? Like "Genius of the Century" Elon Musk is pouring billions into trying to get man to Mars while actively helping to making earth unlivable.
Like no one should be allowed to leave this rock until it either becomes Paradise or worse than fucking Mars!
Not my point. Advancement should never be stopped but us as a civilization needs push that science towards solving the most immediate and important problems.
Just a observation. Wish it was reality. But with enough social collaboration we can make one man's wet dream of being the last of humanity, while spreading his "Superior" seed across the cosmos; socially, financially, and legally unacceptable.
Scientific advancement in space experimentation leads to breakthroughs in other areas - all scientific progress is interconnected.
"Pushing science towards solving the most immediate and important problems" is sort of a nonsense statement, as there could be new efficiencies/strategies that are discovered in fields that are completely unrelated to what would normally be associated with "the most immediate and important problems."
We have many many scientists working on "important problems".
We do not have a deficit in research or curiosity, we have an issue with people willfully implementing policy that is detrimental. (Power, Profit, willful ignorance, intending to hurt others, etc)
Actually, space civ or anywhere else for that matter will serve as an excellent research lab experiment to solve Earth's problems.
I'm not in favor of the tech bro++ oligarchy at all, and I believe this is going to get a good bit worse before it gets better for a specific reason of what will happen after the first M-type asteroid in NEO is successfully mined.
One must look at the situation on Earth from an uninvolved 3rd party perspective. Everything humans do is just a form of complex social hierarchy like any other animals. The primary form if display is the barbaric primitivism of collecting the fundamental means of survival; wealth. There is little incentive to display in other more advanced forms like reputation (academia/film industry), or merit (Olympics/military), within the broader population. One can behave terribly and ameliorate a massive share of the real cost using the environmental container to distribute the tax. In space, that is simply not possible. Sustainability is only possible within the elemental cycles. Existence becomes the driving factor. The economy of social hierarchy instead shifts to more advanced forms such as merit and reputation. The most fundamental resource and struggle becomes the heat budget in most instances. This fundamental shift is very important to future history as it creates the technology and engineering mindset that the environmental container is not a valid unlimited resource. Once the technology exists at smaller scales in space, it can be implemented at greater scale on Earth. The financial burden to iterate this tech and refine it to the point where it can be practical on Earth with little cost increase is simply not viable at all, not even for government programs. The big difference is M-type asteroids. Few talk about this, but elemental resource scarcity on any round planet is due to gravitational differentiation. The moment humans access a large M-type astroid (the core of a differentiated planetesimal that has broken up), all wealth accessed in the Holocene is basically irrelevant. The moment that happens, within a generation there will be space colonies. Everything else happening in space is basically taking this into context. Japan in leading the way on prospecting and mining exploration at the moment. They are the most relevant group to watch at the moment.

Especially considering the samples were exposed to supergravity as the plane came out of its dive. I feel like that would mostly invalidate whatever they were hoping to find.
Also, why do they dismiss asking ISS staff to participate in studies? Bodily autonomy doesn't mean you can't ask someone to conduct .. uh... research with you. It just means you have to respect it they say no. Astronauts seem like the types who wouldn't mind putting in a little extra effort for... science.

Too many other introduced variables? Microgravity has a lot of other systemic effects on the astronauts that might affect sperm motility, even before effects to the sperm themselves. Or just individual variation/genetics on the part of the astronauts themselves.
They wouldn't be able to get a sperm sample that wasn't affected by microgravity from the astronauts to begin with.
incredibly... useless.. compared to sperm generated in space
That's what I don't get. Transporting fresh sperm is not an issue that anyone cares about in space colonization. Sperm will get there in two ways: frozen or made on the spot.

After sparing this paper a fair bit of attention I feel I've wasted it.
Nowhere in the paper could i find in what conditions the test samples were kept during the experiment.
This is pretty basic stuff.
At this stage I'd wage sloshing was the issue.
Reading this part of the methodology:
"2.2 Initial sperm analysis
After liquefaction...
[Two paragraphs later, in the same section: ]
After this first analysis, the 15 sperm samples were split into two fractions. All the samples were exposed to 'Parabolic flight' (split 1) and to..."
Did they liquefied the samples and tested like that? Whaa?
The "After this first analysis" should not be in the "2.2 Initial sperm analysis". It just shouldn't!
Then I think "15 sperm samples were split into two fractions". ... "the samples were exposed to 'Parabolic flight' (split 1)" --- splits, fractions, what a mess!!
At this stage I've wasted enough.
The paper should be retracted, the reviewers spanked and the editor fired.

Eight killed in stabbing attack at school in eastern China, police say
Eight people have been killed and 17 others wounded in a knife attack at a vocational school in Wuxi city, eastern China, police said.The attack occurred at the Wuxi Vocational Institute of Arts and Technology in Yixing County at about 6:30pm local time (10:30 GMT), the Yixing police said in a statement.
Police said the suspect was a 21-year-old former student at the school, who was meant to graduate this year, but had failed his exams.
“He returned to the school to express his anger and commit these murders,” police said, adding that the suspect had confessed.
This is the second deadly attack within a week after a man drove his car into people at a sport facility in the southern city of Zhuhai, leaving 35 people dead and injuring 43 others.
And there has been a spate of other attacks in recent months.
In October, in Shanghai, a man killed three people and wounded 15 others in a knife attack at a supermarket.
And the month before, a Japanese schoolboy was fatally stabbed in the southern city of Shenzhen, which borders Hong Kong.

Hungary turns to China to boost recession-hit economy
Viktor Orbán has turned Hungary into the main home for Chinese capital in Europe, capturing more than a quarter of all Chinese investment coming into the continent over the past two years.The outsized share, including a wave of investment into EV factories, has been a fillip to an otherwise struggling Hungarian economy hit by the EU withholding about €20bn of funding over rule of law concerns.
Orbán’s challenge now is pulling off the diplomatic gymnastics required to simultaneously remain an ally to Xi Jinping and Donald Trump’s incoming administration of China hawks, while managing the threat of a chronic decline in EU funds.
Even against the backdrop of his rule of law dispute with Brussels, Orbán has exacerbated tensions with other EU capitals by maintaining strong diplomatic ties with both Beijing and Moscow.
Márton Nagy, economy minister and a former adviser to prime minister Orbán, told the Financial Times that China’s investments had helped maintain the country’s car industry as “a very strong core” of its economy, which is eventually expected to account for almost a third of GDP.

A lot of people have trouble getting motivated.
Your comment made me chuckle a little bit.
I ask myself that same question every day. What's the point of anything? Do I really need to get out of bed, get to work, eat food, climb out of the debt trap I'm in or even browse Lemmy?
Something like this could help ease that daily question from myself. If it doesn't work, it's fine. Worth a shot. Free is cheaper than recreational drugs.
Which health apps do you recommend?
I maintain my own list of open source software, but one of the biggest struggles has been finding open source health apps to add to the list. It seems like the open source community is lacking in this area, compared to proprietary counterparts.
I'm beginning to flesh out some of the health apps on my list, and I am looking for recommendations on which apps are generally used. This is an extremely rare circumstance in which I am asking for community feedback to add software to the list.
My preferred criteria is as follows:
Available for Android
It can be available for other platforms, but I tend to prioritize open source operating systems such as Android or Linux. In this case, a health app for Linux would rarely be useful. If available, please note whether or not the app works well with strict permissions on GrapheneOS.
Has a clear, distinct purpose
I prefer not to categorize the same app in multiple places. I am a believer of software being the best at one thing, rather than trying to be the best at everything. So, I would like to categorize different apps for each purpose (calorie tracking, nutritional information, fitness tracking, etc.)
Works entirely offline
Ideally, apps should work without ever requiring an internet connection. Having the ability to download data for offline use later is fine, if the data is large enough to warrant not being packaged with the app itself.
Still actively maintained
It's rare that I add outdated or abandoned apps to my list, but there will always be exceptions. The apps should be actively maintained, and have modern usability and appearance.
Those are best case-scenario criteria, your recommended app may not follow that. All apps should, of course, be open source. I am leaving the definition of "health apps" without elaboration on purpose, because I am looking for all health-related and physical wellbeing apps.
Thank you for your suggestions! :)

I have been using Gadgetbridge for several years. The developers are very active, with the nightly branch being released daily. I've collaborated with some of them to debug issues and add support for new devices.
I've used it with multiple watches and a scale. While it doesn't provide insights or interpretations of your data like proprietary apps do, it offers complete control over your data. I've been planning to set up a SQLite to InfluxDB/Grafana translation layer to obtain more detailed statistics.
