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.

Stockholm, Jun 15: Nuclear powers continue to modernise their arsenals, researchers said Monday, warning that tensions were rising and the outlook for arms control was "bleak".

"The loss of key channels of communication between Russia and the USA... could potentially lead to a new nuclear arms race," said Shannon Kile, director of the nuclear arms control programme at the Stockholm International Peace Research Institute (SIPRI) and co-author of the report.

Russia and the US account for more than 90 percent of the world's nuclear weapons.

Kile was referring to the future of the New START treaty between the US and Russia, which is set to expire in February 2021.

It is the final nuclear deal still in force between the two superpowers, aimed at maintaining their nuclear arsenals below Cold War levels.

"Discussions to extend New START or to negotiate a new treaty made no progress in 2019," the SIPRI researchers noted.

At the same time, nuclear powers continue to modernise their weapons while China and India are increasing the size of their arsenals.

"China is in the middle of a significant modernisation of its nuclear arsenal. It is developing a so-called nuclear triad for the first time, made up of new land- and sea-based missiles and nuclear-capable aircraft," SIPRI said.

The country has repeatedly rejected Washington's insistence that it join any future nuclear arms reduction talks.

The number of nuclear warheads declined in the past year.

At the start of 2020, the United States, Russia, Britain, China, India, Pakistan, Israel and North Korea together had 13,400 nuclear arms, according to SIPRI's estimates, 465 fewer than at the start of 2019.

The decline was attributed mainly to the United States and Russia.

While the future of the New START treaty remains uncertain, Washington and Moscow have continued to respect their obligations under the accord.

"In 2019, the forces of both countries remained below the limits specified by the treaty," the report said. But both nations "have extensive and expensive programmes underway to replace and modernise their nuclear warheads, missile and aircraft delivery systems, and nuclear weapon production facilities," it added.

"Both countries have also given new or expanded roles to nuclear weapons in their military plans and doctrines, which marks a significant reversal of the post-Cold War trend towards the gradual marginalisation of nuclear weapons."

The Treaty on the Non-Proliferation of Nuclear Weapons (NPT), a cornerstone of the global nuclear non-proliferation regime, celebrates its 50th anniversary this year.

The number of nuclear arms worldwide has declined since hitting a peak of almost 70,000 in the mid-1980s.

The five original nuclear powers -- Washington, Beijing, Moscow, Paris and London -- in March reiterated their commitment to the treaty.

Washington, Apr 17: A record number of 4,591 Americans have died in the last 24 hours due to the deadly novel coronavirus in the US, which has the highest number of COVID-19 casualties in the world.

According to the Johns Hopkins University data, by 8 pm on Thursday, as many as 4,591 Americans have died in the last 24 hours, The Wall Street Journal said.

The previous highest was 2,569 on Wednesday.

By Thursday, more than 662,000 Americans tested positive with the coronavirus.

The dreaded disease, which originated in Wuhan city in China in December last year, has so far claimed more than 144,000 lives and infected over 2.1 million people.

The virus has infected over 671,000 people and claimed more than 33,000 lives, the highest for any country in the world.

New York City and its adjoining areas, including New Jersey and Connecticut have emerged as the epicenter of the virus in the US.

New York alone accounts for 226,000 cases of infections and 16,106 deaths.

In New Jersey, as many as 3,518 people have died of the disease and 75,317 have tested positive.

According to the US Centers for Disease Control and Prevention, till April 14, four per cent of the Americans infected with COVID-19 were of Asian origin and nearly one-third (30 per cent) were African Americans.

US President Donald Trump told reporters at the White House that experts and scientists report that his strategy to slow the spread of the virus has saved hundreds of thousands of lives.

Models predicted between 1.5 million and 2.2 million US deaths. If there was no mitigation, it could have even been higher than that and between 100,000 and 240,000 deaths with mitigation. It is looking like we will come far under even these lowest numbers, he said.

Noting that experts say the curve of the virus has flattened, and the peak in the new cases has passed, Trump said that nationwide, more than 850 counties or nearly 30 per cent of the country have reported no new cases in the last seven days.

Because of our early and aggressive action, we have avoided the tragedy of health care rationing and deadly shortfalls that have befallen in many other nations, nations which wherever possible we are helping, he said.

According to Trump, at least 35 clinical trials are already underway, including antiviral therapies, immune therapies, and blood therapies in the form of convalescent plasma. So far, more than 3.5 million tests have been carried out.

Islamabad, Apr 26: Pakistan Prime Minister Imran Khan has been trumped by the country's powerful military yet again, this time over his government's inadequate steps and its poor response in curbing the coronavirus outbreak in the country, even as cases soared over 12,500.

In his address to the nation on March 22, Khan explained the reasons for not imposing a countrywide lockdown, asserting that millions would lose their jobs and affect families, who are below the poverty line, struggling to find enough food to eat. However, less than 24 hours later, Pakistan Army spokesperson Major General Babar Iftikhar announced the implementation of lockdown in the country having a population of over 200 million, contradicting the statements made by Imran Khan.

As lockdown was imposed, the military has deployed troops across Pakistan and is orchestrating the COVID-19 response through the National Core Committee, a body set up to coordinate policy between the national and provincial governments.

"The government left a big gap in its handling of the coronavirus. The army has tried to fill that gap, there was no choice," an unnamed retired general was quoted by Financial Times as saying.

The virus crisis in Pakistan has once again made things crystal clear about who is calling the shots -- the military, widely believed to bring Imran Khan to power in 2018.

The armymen have taken over the COVID-19 crisis as an opportunity to prove their competency in contrast to Imran Khan, who was mocked after urging youth to come forward and join Corona Relief Tigers Force, a volunteer body to wage "jihad" against the virus.

According to analysts, the military's seizure of the coronavirus response marks yet another policy failure for Imran Khan in the eyes of the generals, as per the Financial Times report.

The 67-year-old cricketer-turned-politician has repeatedly failed to gain international traction over the Kashmir issue and has struggled to convince the Financial Action Task Force (FATF) in getting his country removed from 'grey list' for terror funding.

In times of emergency, one has to take clear decisions and take them through. You can't dither. The whole world is advising strong lockdown. If the prime minister does not show that he is decisive, somebody else will," said Nafisa Shah, a Member of Parliament from the opposition Pakistan Peoples Party (PPP).

Even after the lockdown was imposed, Imran Khan continued to question the need for its implementation, raising eyebrows over the country's response in tackling the virus, as cases continue to rise. This comes even as such drastic measures are in place in many countries across the world, including neighbouring India.

According to The Dawn, the country has 12,657 confirmed cases of COVID-19, which includes 2,755 recoveries and 265 deaths. Punjab has the highest number of cases -- 5,326 --, followed by 4,232 in Sindh.

However, experts suggest that the actual numbers could be more given the low testing rates and inadequate supply of testing kits.

Doctors and nurses across the country have staged protests over the lack of personal protective equipment, as increasing numbers of health workers contract COVID-19.

"Because of the lack of resources, there is chaos among the doctors and healthcare workers. They know people are dying, they know the severity of the illness and they have to work without PPE," Shoaib Hasan Tarar, a doctor working in Rawalpindi, was quoted as saying.

As the coronavirus crisis continues to ravage Pakistan, the country's overwhelming health infrastructure has put a toll on its already floundering economy. The IMF said that the GDP will shrink 1.5 per cent in 2020. The cash-strapped nation is set to be the first major emerging economy to apply to a G-20 initiative to request debt repayment relief, according to Financial Times.

In early March, Pakistan saw a surge in coronavirus cases, when infected pilgrims and workers crossed the border from Qom, a religious city in Iran, which is a hotspot.

Pakistan's limited resources were exposed when quarantined pilgrims agitated against unhealthy conditions at Taftan camp on Pakistan-Iran border, where five people were living in a tent with no access to toilets.

While the lockdown is in place, authorities have been confronted by hardline clerics who have defied social distancing terms and downplayed the threat of the virus. During Friday prayers every week, worshippers violate the restrictions by gathering at various mosques.

Last week, Islamabad inked an agreement allowing mosques to stay open for Ramzan. It stipulated that people should follow 20 rules, including maintaining a six feet distance from each other.

"There is little consistency in terms of how the lockdown is being approached. Coronavirus has shown the disconnect between the national government, regional governments and the military. Imran Khan has been left behind as the cheerleader for keeping Pakistan's morale high. I think people are starting to ask, 'How long is he going to last?'", said Sajjan Gohel, South Asia expert and guest teacher at the London School of Economics.
