African teens come up with 'pee-powered' generator

London, November 12: In a breakthrough, four teenage schoolgirls in Nigeria have invented a ‘pee-powered' generator that converts one litre of urine into six hours of electricity.


Fourteen-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola presented their invention at the Maker Faire Africa entrepreneurs event, in Lagos, using a resource that is free, unlimited and easily obtainable.

According to the Maker Faire blog, urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and hydrogen.

The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder, the Daily Mail reported.

The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.

This purified hydrogen gas is pushed into the generator, and one litre of urine provides six hours of electricity.

Maker Faire blog described the generator as “possibly one of the more unexpected products” at the event.

While the system does have one-way valves for safety, more robust measures may be needed before it can be sold widely.

The report noted: “Let's be honest that this is something of an explosive device”.


Nigeria's economy is on the rise, however, more than half of the country's 162 million citizens have no access to electricity, and even those who do can't guarantee having power every day, the report said.

Washington, May 12: The US Federal Bureau of Investigation and cybersecurity experts believe Chinese hackers are trying to steal research on developing a vaccine against coronavirus, two newspapers reported Monday.

The FBI and Department of Homeland Security are planning to release a warning about the Chinese hacking as governments and private firms race to develop a vaccine for COVID-19, the Wall Street Journal and New York Times reported.

The hackers are also targeting information and intellectual property on treatments and testing for COVID-19.

US officials alleged that the hackers are linked to the Chinese government, the reports say.

The official warning could come within days.

In Beijing Foreign Affairs ministry spokesman Zhao Lijian rejected the allegation, saying China firmly opposes all cyber attacks.

"We are leading the world in COVID-19 treatment and vaccine research. It is immoral to target China with rumors and slanders in the absence of any evidence," Zhao said.

Asked about the reports, President Donald Trump did not confirm them, but said: "What else is new with China? What else is new? Tell me. I'm not happy with China."

"We're watching it very closely," he added.

A US warning would add to a series of alerts and reports accusing government-backed hackers in Iran, North Korea, Russia and China of malicious activity related to the pandemic, from pumping out false news to targeting workers and scientists.

The New York Times said it could be a prelude to officially-sanctioned counterattacks by US agencies involved in cyber warfare, including the Pentagon's Cyber Command and the National Security Agency.

Last week in a joint message Britain and the United States warned of a rise in cyber attacks against health professionals involved in the coronavirus response by organised criminals "often linked with other state actors."

Britain's National Cyber Security Centre and the US Cybersecurity and Infrastructure Security Agency said they had detected large-scale "password spraying" tactics -- hackers trying to access accounts through commonly used passwords -- aimed at healthcare bodies and medical research organisations.

London, Apr 30: The coronavirus is roiling global job markets, but the picture is not all gloomy. Finance, technology and consumer goods firms are hiring tens of thousands in the United States and other countries, according to data from Microsoft Corp's professional networking site LinkedIn.

Across seven countries in North America, Europe and Asia, healthcare providers are among the busiest recruiters given the ongoing battle against the novel coronavirus, which has killed over 200,000 people and infected over 3 million people worldwide, LinkedIn said. But lifestyle changes during lockdown are also driving demand for financial consultants, factory workers, animators and game designers, and delivery workers.

Overall, the hiring rate has plunged in the first quarter from the year-ago period, and in late April remains lower than a year ago across most countries surveyed by the platform. But the data offer a glimmer of hope with a gradual uptick in China, where the coronavirus emerged last year and which leads the world in surfacing from a months-long lockdown.

LinkedIn, with over 690 million users worldwide, counts new hires when people add a new employer to their profile. The rate is the number of new hires divided by the total number of LinkedIn members in a country.

The figures, tracked since mid-February, are not corroborated by official jobs data and do not represent the actual number of jobs in an economy. Government figures are usually released with a time-lag of several weeks.

"We are confident that our data is directionally correct in that there has been a huge decline in hiring in the U.S. and abroad," Guy Berger, principal economist at LinkedIn in California, told Reuters.

Hiring in China plummeted 50% during the height of its coronavirus crisis in mid-February from 12 months earlier. Since restrictions were eased in early April, the hiring rate has inched up, and for the week ending April 24 was 3% lower than the same period in 2019.

Hiring in the United States, United Kingdom, France and Italy - which lead the world in coronavirus-related deaths - remains hugely depressed, but is falling less rapidly than a few weeks ago as the countries pass the peak of their epidemics.

Retailers including Walmart Inc, Amazon.com Inc and Instacart have said they would hire a total of over 700,000 workers to meet a surge in demand for groceries and household essentials during the coronavirus outbreak.

Coronavirus state-wise India update: Total number of confirmed cases, deaths on April 30

Consumer goods manufacturers such as Unilever, whose products include soap and shampoo, confirmed on Wednesday it was hiring to fill 300 jobs globally, but declined to elaborate.

Nestle told Reuters it was looking to fill 5,000 full-time U.S. positions in "a variety of levels across corporate and frontline."

Fidelity Investments, a Boston-based financial services firm, said it had accelerated recruitment because of the pandemic and was looking to fill at least 2,000 full-time roles for financial consultants, software engineers and customer service staff in the United States in 2020.

Companies hiring in the United States and other countries also include Apple Inc; ByteDance, the Chinese parent of video-sharing social network TikTok; Takeda Pharmaceutical Co Ltd; and aerospace and defence company Lockheed Martin Corp. These companies did not immediately respond to requests for comment.

DIRE WARNINGS

The International Labour Organization warned on Wednesday that 1.6 billion workers, or nearly half of the global workforce, especially in the informal economy, could lose their livelihoods.

Record numbers of people have applied for U.S. jobless benefits since mid-March, and the unemployment rate is expected to soar to 16%, White House economic adviser Kevin Hasset said this week, from a 50-year low of 3.5% before the pandemic hit.

Both Italy and France, in lockdown for nearly two months, have seen hiring rates drop by around 70% from a year ago, according to LinkedIn.

Since China is ahead of other countries on the pandemic timeline, improvements there could suggest the same is in store elsewhere, Berger said. Several American states and European countries have begun allowing some non-essential businesses and schools to reopen in the hopes of restarting the economy and allowing a gradual return to normal life.

"It's still slightly early to call it a firm recovery," Berger said, referring to improving prospects in China. "We're not expecting a full recovery but rather it's an indication that parts of the economy will switch on as lockdowns are eased, at least relative to the worst point of the pandemic."

Dubai/Washington, Jan 7: Iran's Supreme Leader Ayatollah Ali Khamenei wept in grief with hundreds of thousands of mourners thronging Tehran's streets on Monday for the funeral of military commander Qassem Soleimani, killed by a U.S. drone on U.S. President Donald Trump's orders.

The coffins of General Qassem Soleimani and Iraqi militia leader Abu Mahdi al-Muhandis, who also died in Friday's attack in Baghdad, were draped in their national flags and passed from hand to hand over the heads of mourners in central Tehran.

Responding to Trump's threats to hit 52 Iranian sites if Tehran retaliates for the drone strike, Iran's President Hassan Rouhani pointedly wrote on Twitter: "Never threaten the Iranian nation." And Soleimani's successor vowed to expel U.S. forces from the Middle East in revenge.

Khamenei, 80, led prayers at the funeral, pausing as his voice cracked with emotion. Soleimani, 62, was a national hero in Iran, even to many who do not consider themselves supporters of Iran's clerical rulers.

Aerial footage showed people, many clad in black, packing thoroughfares and side streets in the Iranian capital, chanting "Death to America!" - a show of national unity after anti-government protests in November in which many demonstrators were killed.

The crowd, which state media said numbered in the millions, recalled the masses of people that gathered in 1989 for the funeral of the Islamic Republic's founder, Ayatollah Ruhollah Khomeini. Soleimani, architect of Iran's drive to extend its influence across the Middle East, was widely seen as Iran's second most powerful figure behind Khamenei.

His killing of Soleimani has prompted concern around the world that a broader regional conflict could flare.

Trump on Saturday vowed to strike 52 Iranian targets, including cultural sites, if Iran retaliates with attacks on Americans or U.S. assets, and stood by his threat on Sunday, though American officials sought to downplay his reference to cultural targets. The 52 figure, Trump noted, matched the number of U.S. Embassy hostages held for 444 days after the 1979 Iranian Revolution.

Rouhani, regarded as a moderate, responded to Trump on Twitter.

"Those who refer to the number 52 should also remember the number 290. #IR655," Rouhani wrote, referring to the 1988 shooting down of an Iranian airline by a U.S. warship in which 290 were killed.

Trump also took to Twitter to reiterate the White House stance that "Iran will never have a nuclear weapon" but gave no other details.

'ACTIONS WILL BE TAKEN'

General Esmail Ghaani, Soleimani's successor as commander of the Quds Force, the elite unit of Iran's Revolutionary Guards charged with overseas operations, promised to "continue martyr Soleimani's cause as firmly as before with the help of God, and in return for his martyrdom we aim to rid the region of America."

"God the Almighty has promised to take martyr Soleimani's revenge," he told state television. "Certainly, actions will be taken."

Other political and military leaders have made similar, unspecific threats. Iran, which lies at the mouth of the key Gulf oil shipping route, has a range of proxy forces in the region through which it could act.

Iran's demand for U.S. forces to withdraw from the region gained traction on Sunday when Iraq's parliament passed a resolution calling for all foreign troops to leave the country.

Iraqi caretaker Prime Minister Abdel Abdul Mahdi told the U.S. ambassador to Baghdad on Monday that both nations needed to implement the resolution, the premier's office said in a statement. It did not give a timeline.

The United States has about 5,000 troops in Iraq.

Soleimani built a network of proxy militia that formed a crescent of influence - and a direct challenge to the United States and its regional allies led by Saudi Arabia - stretching from Lebanon through Syria and Iraq to Iran. Outside the crescent, Iran nurtured allied Palestinian and Yemeni groups.

He notably mobilised Shi'ite Muslim militia forces in Iraq that helped to crush ISIS, the Sunni militant group that had seized control of swathes of Syria and Iraq in 2014.

Washington, however, blames Soleimani for attacks on U.S. forces and their allies.

The funeral moves to Soleimani's southern home city of Kerman on Tuesday. Zeinab Soleimani, his daughter, told mourners in Tehran that the United States would face a "dark day" for her father's death, adding, "Crazy Trump, don't think that everything is over with my father's martyrdom."

NUCLEAR DEAL

Iran stoked tensions on Sunday by dropping all limitations on its uranium enrichment, another step back from commitments under a landmark deal with major powers in 2015 to curtail its nuclear programme that Trump abandoned in 2018.

In response, European signatories may launch a dispute resolution process against Iran this week that could lead to a renewal of the United Nations sanctions that were lifted as part of the deal, European diplomats said on Monday.

Diplomats said France, Britain and Germany could make a decision ahead of an EU foreign ministers' meeting on Friday that would assess whether there were any ways to salvage the deal.

After quitting the deal, the United States imposed new sanctions on Iran, saying it wanted to halt Iranian oil exports, the main source of government revenues. Iran's economy has been in freefall as the currency has plunged.

Trump adviser Kellyanne Conway said on Monday that he was still confident he could renegotiate a new nuclear agreement "if Iran wants to start behaving like a normal country."

Tehran has said Washington must return to the existing nuclear pact and lift sanctions before any talks can take place.

The United States advised American citizens in Israel and the Palestinian territories to be vigilant, citing the risk of rocket fire amid heightened tensions. As a U.S. ally against Iran, Israel is concerned about possible rocket attacks from Gaza, ruled by Iranian-backed Palestinian Islamists, or major Iran proxy Hezbollah in Lebanon.

Democratic critics of Trump have said the Republican president was reckless in authorising the strike, with some saying his threat to hit cultural sites amounted to a vow to commit war crimes. Trump also threatened sanctions against Iraq and said Baghdad would have to pay Washington for an air base in Iraq if U.S. troops were required to leave.
