Does anyone still remember the initial phase of the Corona pandemic in 2020? When shops, restaurants, cinemas, and theatres remained closed. When meetings with friends and relatives were prohibited. When school lessons had to take place at home in the children's rooms. When there was no question of traveling.

Presently, most people seem to have long forgotten these times. Yet, the various corona measures taken by politicians are likely to have caused enormous stress for many. The fear for the job, the worry about sick relatives, the nervous strain when parents and children sit together in a small apartment and have to reconcile home office and homeschooling: All this has not remained without effects, as numerous studies show. The crucial factor is anxiety

How and to what extent have these experiences affected the mental health and quality of life of women and men in the first year of the COVID-19 pandemic? This has been investigated by a research team of the University and the University Hospital Würzburg.

In detail, the scientists were interested in the relationship between worries about the workplace and about other people with a person's own mental health problems such as anxiety and depression and with their quality of life in general, how these are influenced by the support from friends or at work – and whether the results show differences between men and women.

The findings are unambiguous: in this complex of different variables and influencing factors, anxiety plays a central part. There are, however, distinct gender-specific differences: In men, anxiety increases along with concerns about the job, an effect which does not show in women. On the other hand, we were able to register an increase in anxiety levels in women parallel to an increase in their worries about family and friends."

In addition, the study shows that women in such times respond positively to support from friends and family by experiencing enhanced quality of life. In men, this phenomenon did not manifest itself. Data on the influence of gender were lacking

Grit Hein is Professor of Translational Social Neuroscience at the Clinic and Polyclinic for Psychiatry, Psychosomatics and Psychotherapy at the University Hospital. She and her postdoc Martin Weiβ led the study, the results of which have now been published in the journal Scientific Reports.

"In the past, numerous studies have investigated the influence of psychosocial factors such as support from friends and colleagues and financial, professional or personal worries on mental health and the quality of life. Yet, data on whether these correlations are the same for men and women were lacking," says Grit Hein, explaining the background to the study. Broadening earlier studies, the Würzburg research team has therefore now examined the influence of these factors in relation to gender. A study with around 2,900 participants

The team obtained the relevant information from a large group of test subjects: the participants of the so-called STAAB study. This study comprises a cohort of around 5,000 randomly selected volunteers from the general population of Würzburg and originally focused on the development of cardiovascular diseases. During the COVID-19 pandemic, the program was spontaneously expanded to include the psychosocial impacts of the pandemic, the lockdown, and other side effects.

A total of 2,890 people (1,520 women and 1,370 men) took part in the survey. Their ages ranged from 34 to 85 years, with a median of 60 years. Between June and October 2020, they had to fill out an extensive questionnaire about their mental health. Among other things, they were asked to provide information about how strongly they felt supported by their social environment, their colleagues and superiors, and whether they had someone with whom they could discuss their problems.

They were also asked to what extent bans on the contact with parents and grandparents burdened them and how much stress they felt at work or at school. Financial problems or worries about them were the subject of further questions.

To evaluate the data, Hein and her team used a special method: the so-called network analysis. "Analyses based on a network approach enable a graphical representation of all variables as individual nodes," Hein explains. Thus, it is possible to identify variables that are particularly related to other variables. The network can, for example, show complex relationships between symptoms of different mental disorders and thus explain possible comorbidities. Results fit traditional gender norms

Grit Hein and Martin Weiβ were hardly surprised by the results. "The observation that men are more strongly associated with work and women more strongly with family and friends can be traced back to traditional gender norms and roles," Hein explains. Hence, men usually feel more affected by job insecurity and unemployment, which leads to higher psychological stress. Women, on the other hand, experience more strain when they feel that they are neglecting their family.

It is also plausible that women cope better psychologically when they receive support from friends and family: "This is in line with the traditional female family role, which includes a stronger tendency to maintain close social contacts and to seek social support in order to reduce stress and increase well-being," says Hein.

Even though these findings are unambiguous, the study leaders point to a number of limitations. The most important: "Since the COVID-19 pandemic presented a very specific context, it remains to be clarified whether our results are transferable to general pandemic-independent situations." One finding, however, is indisputable: "Our results underline the need to consider social aspects in therapeutic interventions in order to improve the mental health of women and men." Source:

Investors sue Meteora and VC firm, alleging fraud

Investors sue Meteora and VC firm, alleging fraud

A group of investors has filed a class-action lawsuit against decentralized cryptocurrency exchange Meteora, alleging the firm was involved in manipulating the launch and market price of the M3M3 token.

In an amended complaint filed on April 21 in the US District Court for the Southern District of New York, the plaintiffs allege that venture capital firm Kelsier Labs, Meteora, and four current or former executives “intentionally misrepresented” information in the M3M3 launch in December 2024.

The investors claimed that they suffered at least $69 million in losses between December 2024 and February 2025 after the parties presented “trusted leaders in the Solana ecosystem” as being behind the token launch, rather than a “blatant fraud” in which sales were manipulated to artificially inflate the price.

“This artificially-inflated valuation communicated highly misleading information to non-insider investors, who reasonably relied on Defendants’ representations that the $M3M3 launch was fully accessible to the public and conducted in a transparent manner fair to non-insider investors, and thus reasonably relied on $M3M3 market price as a meaningful measure of its value,” the complaint reads. “The post-launch price spike also served to corroborate Defendants’ aggressively-marketed, but misleading, assertions that $M3M3 had intrinsic value and a comparatively low risk profile.”

The lawsuit is one of many involving different crypto firms that have alleged fraud through violations of US securities laws. Though the US Securities and Exchange Commission (SEC), under acting chair Mark Uyeda since US President Donald Trump took office, has scaled back or dismissed many enforcement actions involving digital assets, the agency said in February it still intended to pursue cases against fraudulent token projects.

The investors added:

“Together, Defendants designed the $M3M3 Token and planned its launch on Meteora in a manner intended to illicitly enrich themselves at the expense of the unsuspecting investing public.”

Memecoins in the Solana ecosystem

Meteora has been tied to the launch of several high-profile yet controversial tokens, including those for Trump (TRUMP), his wife Melania (MELANIA), Libra (LIBRA), and online influencer Haliey Welch (HAWK).

According to the lawsuit, the firm “purported to offer a comprehensive solution to the problems in the memecoin investment market” with the launch of M3M3. The defendants in the case allegedly attempted to distinguish the token from other notable memecoins by highlighting the “legitimacy and trustworthiness” through the involvement of Meteora co-founder Ben Chow and the platform.

Kelsier Ventures, KIP Protocol, and Meteora face a similar class-action lawsuit filed in New York in March over LIBRA allegedly being launched in a “deceptive, manipulative and fundamentally unfair” manner. Argentine President Javier Milei briefly promoted the token over social media after his sister reportedly received payments from the project.

CATL unveils new EV battery that charges as fast as pumping gas

China’s Contemporary Amperex Technology Co., Limited (CATL) has unveiled its latest battery cell technologies, which charge as quickly as filling up a gas tank while potentially lowering costs without compromise.

CATL has quickly become the world’s largest battery manufacturer by a wide margin. It is one of, if not the biggest, force for advancing electric transportation.

A big part of CATL’s success is due to its advancements in lithium-iron phosphate battery cells, also known as LFP. LFP cells are cheaper than nickel-rich batteries, but they used to have much lower energy density.

The Chinese battery manufacturers managed to close the gap somewhat while maintaining lower costs, resulting in LFP cells becoming popular for entry-level EVs.

Now, CATL is looking to do the same with sodium-ion batteries.

Like LFP cells, sodium-ion battery cells have the potential to be cheaper than more common Li-ion cells, but they also offer potential for superior performance, particularly in terms of faster charging and longer lifecycles.

CATL has unveiled today Naxtra, its new sodium-ion battery cells, and it claimed some truly impressive specs.

The new cell reportedly achieves an energy density of 175 Wh per kg (385 Wh per lb), on par with the higher-end of LFP battery cells.

The new cells also offer potential for significant safety improvements.

CATL shared several intense stress tests, including drilling into a cell and even cutting it in half without any thermal event:

The next-gen sodium cells could help further lower the cost of electric vehicles without compromising performance, and while increasing safety.

On top of the new Naxtra cell, CATL has also unveiled its next-gen Shenxing LFP battery cells.

Its charge rate is truly impressive. CATL shared several examples of cars charging at around 1,000 kW and maintaining over 500 kW at over 50% state of charge:

The new cell is being described as capable of adding 300 miles (482 km) of range in about 5 minutes – depending on the EV model.

That’s virtually as quick as filling up a tank of gas.

CATL says that the Shenxing will be in 67 electric vehicle models by the end of the year.

The next-gen cell was unveiled after BYD, CATL’s biggest competitor, also unveiled its latest technology, capable of charging electric vehicles at extremely high speeds.

Tesla shares tumble ahead of first-quarter earnings report

Tesla shares tumble ahead of first-quarter earnings report

Tesla shares fell almost 6% on Monday, a day ahead of the electric vehicle company’s first-quarter earnings report, as analysts fret over “ongoing brand erosion.”

The stock closed at $227.50 leaving it less than $6 above its low for the year on April 8. The shares are now down 44% for the year after wrapping up their worst quarter since 2022 in March. It’s the 12th time this year the stock has dropped by at least 5% in a single session.

CEO Elon Musk’s many distractions outside of Tesla, especially his role within the Trump administration, are in focus, along with the company’s progress on a long-delayed robotaxi and self-driving technology for its existing cars.

In the online forum that Tesla uses to solicit investor inquiries in advance of its earnings calls, more than 300 questions were submitted pertaining to Tesla’s self-driving systems, around 200 came in about the company’s Optimus humanoid robots in development, and more than 160 questions poured in about Musk individually. One investor asked, “What steps has the board of directors taken to mitigate the brand damage caused by Elon’s political activities?”

After spending $290 million to help return Trump to the White House, Musk is now leading an initiative to slash tens of thousands of federal jobs, sell off or end leases for federal office buildings, and reduce U.S. government capacity.

Musk’s politics and antics have elicited a massive backlash in Europe and parts of the U.S. This year, the company has been hit with waves of protests, boycotts and some criminal activity that targeted Tesla vehicles and facilities in response to Musk.

Earlier this month, Tesla reported 336,681 vehicle deliveries in the first quarter, a 13% decline from the same period a year earlier.

Tesla Q1 deliveries worse than expected

The company is expected to report revenue of $21.24 billion for the first quarter, according to LSEG, which would mark a slight drop from the same period last year. Analysts expect earnings per share of 40 cents. Investors will be paying particularly close attention to any commentary about Trump’s widespread tariffs and the potential impact on revenue and earnings as the year progresses.

Oppenheimer analysts wrote in a note out Monday that “ongoing brand erosion” for Tesla in the U.S. and Europe is weighing on sales already, but a “bigger issue for the company is potential weakness in China demand and margin impact due to the Trump tariffs.”

They wrote that competition in China, coupled with “nationalistic” consumer trends there, could “drive sales toward domestic brands.” Tesla would then have to export more of its China-made cars, which could lead to “downward pressure on pricing,” the Oppenheimer analysts said.

Caliber, a research firm that tracks how U.S. consumer sentiment is shifting around major brands, found that only 27% of its survey respondents in March would consider purchasing a Tesla, compared to 46% in January 2022.

Wedbush Securities analyst Dan Ives, a longtime Tesla bull, is hoping for a “turnaround vision” from Musk on Tuesday’s earnings call.

“Tesla has now unfortunately become a political symbol globally of the Trump Administration/DOGE,” he wrote, noting that “Tesla’s stock has been crushed since Trump stepped back into the White House.”

Ives estimated 15% to 20% “permanent demand destruction for future Tesla buyers due to the brand damage Musk has created” by working for Trump.

Late last week, Barclays maintained the equivalent of a sell rating and slashed its price target on Tesla to $275 from $325, citing a “confusing set-up” on the first-quarter with “weak fundamentals.” The firm said it could see a positive reaction if Musk is more focused on his automaker, and depending on what the company discloses about an anticipated “FSD event,” referring to Tesla’s Full Self-Driving offering.

Tesla said in announcing its reporting date that, in addition to earnings, it will provide a “live company update,” language the company hasn’t typically used in disclosures.
