Entire Earth vibrating less due to COVID-19 lockdowns says study

In a study conducted in 117 countries, researchers have found that the world is experiencing the most dramatic reduction in the seismic noise (the hum of vibrations in the planet's crust) in recorded history due to global COVID-19 lockdowns.

Measured by instruments called seismometers, seismic noise is caused by vibrations within the Earth, which travel like waves and the waves can be triggered by earthquakes, volcanoes, and bombs - but also by daily human activity like travel and industry.

This quiet period was likely caused by the total global effect of social distancing measures, closure of services and industry, and drops in tourism and travel, the study published in the journal Science, reported.

The new research, led by the Royal Observatory of Belgium and five other institutions around the world including Imperial College London (ICL), showed that the dampening of 'seismic noise' caused by humans was more pronounced in more densely populated areas.

"Our study uniquely highlights just how much human activities impact the solid Earth, and could let us see more clearly than ever what differentiates human and natural noise," said study co-author Stephen Hicks from ICL in the UK.

For the findings, the research team looked at seismic data from a global network of 268 seismic stations in 117 countries and found significant noise reductions compared to before any lockdown at 185 of those stations.

Researchers tracked the 'wave' of quietening between March and May as worldwide lockdown measures took hold.

The largest drops in vibrations were seen in the most densely populated areas, like Singapore and New York City, but drops were also seen in remote areas like Germany's the Black Forest and Rundu in Namibia.

Citizen-owned seismometers, which tend to measure more localised noise, noted large drops around universities and schools around Cornwall, UK and Boston, US - a drop in noise 20 per cent larger than seen during school holidays.

The findings showed that countries like Barbados, where lockdown coincided with the tourist season, saw a 50 per cent decrease in noise.

"The changes have also given us the opportunity to listen in to the Earth's natural vibrations without the distortions of human input," the study authors wrote.

Earlier in April, a study published in the journal Nature, reported at least a 30 per cent reduction in that amount of ambient human noise since lockdown began in Belgium.

Twitter has joined efforts to do away with racially loaded terms such as master, slave and blacklist from its coding language in the wake of the death of African-American George Floyd and ensuing Black Lives Matter protests.

The project started even before the current movement for racial justice escalated following the death of 46-year-old George Floyd in police custody in May.

The use of terms such as "master" and "slave" in programming language originated decades ago. While "master" is used to refer to the primary version of a code, "slave" refers to the replicas. Similarly, the term "Blacklist" is used to refer to items which are meant to be automatically denied.

The efforts to change these terms in favour of more inclusive language at Twitter were initiated by Regynald Augustin and Kevin Oliver and the microblogging platform is now backing their efforts.

"Inclusive language plays a critical role in fostering an environment where everyone belongs. At Twitter, the language we have been using in our code does not reflect our values as a company or represent the people we serve. We want to change that. #WordsMatter," Twitter's engineering team said in a post on Thursday.

As per the recommendations from the team, the term "whitelist" could be replaced by "allowlist" and "blacklist" by "denylist".

Similarly, "master/slave" could be replaced by "leader/follower", "primary/replica" or "primary/standby".

Twitter, however, is not the first to start a project to bring inclusivity in programming language.

According to a report in CNET, the team behind the Drupal online publishing software started using "primary/replica" in place of "master/slave" as early as in 2014.

The use of the terms "master/slave" was also dropped by developers of the Python programming language in 2018.

Now similar efforts are underway at Microsoft's Github and LinkedIn divisions as well, said the report.

Cybercriminals continue to exploit public fear of rising coronavirus cases through malware and phishing emails in the guise of content coming from the Centers for Disease Control and Prevention (CDC) in the US and World Health Organisation (WHO), says cybersecurity firm Kaspersky.

In the APAC region, Kaspersky has detected 93 coronavirus-related malware in Bangladesh, 53 in the Philippines, 40 in China, 23 in Vietnam, 22 in India and 20 in Malaysia. 

Single-digit detections were monitored in Singapore, Japan, Indonesia, Hong Kong, Myanmar, and Thailand. 

Along with the consistent increase of 2019 coronavirus cases comes the incessant techniques cybercriminals are using to prey on public panic amidst the global epidemic, the company said in a statement. 

Kaspersky also detected emails offering products such as masks, and then the topic became more commonly used in Nigerian spam emails. Researchers also found scam emails with phishing links and malicious attachments.

One of the latest spam campaigns mimics the World Health Organisation (WHO), showing how cybercriminals recognise and are capitalising on the important role WHO has in providing trustworthy information about the coronavirus.

"We would encourage companies to be particularly vigilant at this time, and ensure employees who are working at home exercise caution. 

"Businesses should communicate clearly with workers to ensure they are aware of the risks, and do everything they can to secure remote access for those self-isolating or working from home," commented David Emm, principal security researcher.

Some malicious files are spread via email. 

For example, an Excel file distributed via email under the guise of a list of coronavirus victims allegedly sent from the World Health Organisation (WHO) was, in fact, a Trojan-Downloader, which secretly downloads and installs another malicious file. 

This second file was a Trojan-Spy designed to gather various data, including passwords, from the infected device and send it to the attacker.

Feb 5: Tesla is making Elon Musk a lot richer without paying him a dime.

A blistering stock rally has bolstered the value of CEO Musk's 19% stake in the electric car maker by $16 billion since the start of 2020, to $30 billion.

Tuesday's steep climb in the share price could sweeten Musk's payday under his record-breaking compensation package, which is built on stock options that rely on market value targets. Two milestones have now been achieved that could see Musk unlock options worth $1.8 billion.

The controversial chief executive, who is also the majority owner and CEO of rocket maker SpaceX, recently testified that he did not have a lot of cash as he successfully defended himself in a defamation lawsuit. He previously has taken loans using his Tesla shares as collateral.

Musk does not take a salary, choosing instead a risky options package that envisions the stock market value of Tesla rising to $650 billion over 10 years, a prospect that was derided by some investors when the deal was announced in 2018.

That target now looks less crazy. Shares of Tesla have rallied over 50% since the company posted its second consecutive quarterly profit last Wednesday, which was viewed as a major accomplishment for a company competing against established automotive heavyweights including General Motors Co  and BMW.

Tesla shares have climbed about 400% since early June, helped by the company's better-than-expected financial results and ramped-up production at its new car factory in Shanghai.

On Tuesday, Tesla surged as much as 24% before falling back in the final minutes of the trading session to end the day up 13.7%. That put its market capitalization at $160 billion, almost twice the combined value of Ford Motor and General Motors.

The shares had also rallied on Monday, partly fueled by Panasonic Corp's 6752.T saying its automotive battery venture with Tesla was profitable for the first time.

The options Musk was awarded in 2018 vest incrementally based on targets for Tesla's stock market value and its financial performance. The market capitalization would have to sustainably rise by $50 billion increments over the agreement's 10-year period, with the full package payout reached if the market cap reaches $650 billion, as well as the company's meeting revenue and profit targets.

Musk is on his way to seeing his first two tranches of options vest. He achieved operational targets on revenue and adjusted earnings last year.

The rise in Tesla's market capitalization last month to a target of $100 billion opened the way for Musk's first tranche of options to vest. With Tuesday's surging share price, the market capitalization blew past the second target of $150 billion, opening the way for the second tranche to vest. Tesla's market capitalization must stay at or above each target level for one- and six-month averages for each set of options to vest.

Tesla was valued at about $52 billion when shareholders approved the pay package in March 2018, a time when the company faced a cash crunch, production delays and increasing competition from rivals.

A full payoff for Musk would surpass anything previously granted to U.S. executives, according to Institutional Shareholder Services, a proxy advisor that recommended investors reject the pay package deal at the time.

Musk currently owns about 34 million Tesla shares, and his compensation package would let him buy another 20.3 million shares if all his options tranches vest.

When Tesla unveiled Musk’s package, it said he could in theory reap as much as $55.8 billion if no new shares were issued. However, Tesla has since awarded stock to employees and last year sold $2.7 billion in shares and convertible bonds, diluting the value of the stock.

Musk has transformed Tesla from a niche car maker with production problems into the global leader in electric vehicles, with U.S. and Chinese factories. So far it has stayed ahead of more established rivals including BMW and Volkswagen.

Many investors remain skeptical that Tesla can consistently deliver profit, cash flow and growth. More Wall Street analysts rate Tesla "sell" than "buy," and the company's stock is the most shorted on Wall Street.
