Universities return to ‘pen and paper’ exams after students caught using AI to write exams

Australian universities have been forced to change the way they run exams and other assessments amid fears students are using emerging artificial intelligence software to write essays. Major institutions have added new rules which state that the use of AI is cheating, with some students already caught using the software. But one AI expert has warned universities are in an “arms race” they can never win. ChatGPT, which generates text on any subject in response to a prompt or query, was launched in November by OpenAI and has already been banned across all devices in New York’s public schools due…

New wireless TV runs on batteries for 30 days, sticks to wall without mounting hardware

I met Apple's driving force Steve Jobs a few years before his passing. What he imparted stuck with me. If there was one thing he did well, it was innovating with a focus on balancing design with function. The aesthetic meeting point nailed it like no one had ever achieved. You remember in Apple's days of disruptive innovation, Jobs replaced the Sony Walkman with a revolutionary iPod, he took the inside of cellular phones away from wireless providers and reimagined a phone becoming more like a computer on the go with the iPhone. He took a boring gray desktop computer…

President Muhammadu Buhari, yesterday, before the commencement of the Federal Executive Council meeting, launched the National Monitoring and Evaluation platform, EYEMARK, for citizens to adequately and closely monitor projects executed by government.

The President said the Federal Government could no longer depend on its handful of monitoring and evaluation teams to oversee the vast number of infrastructure projects spread nationwide. According to him, it only makes sense to set up suitable channels for citizen scrutiny given that his administration…

What can America’s Patriot missile do for Ukraine?

Patriot missile systems have long been a hot ticket item for the United States and allies in contested areas of the world as a coveted shield against incoming missiles. In Europe, the Middle East and the Pacific, they guard against potential attacks from Iran, Somalia and North Korea. So it was a critical turning point when news broke this week that the US has agreed to send a Patriot missile battery to Ukraine — something Ukrainian President Volodymyr Zelenskyy has sought for months to augment his country’s air defences. US officials have confirmed the agreement, and an official announcement is…

New study shows rising cases of Chronic Kidney Disease in diabetics: What to know

A new study published in The New England Journal of Medicine found that the rate of chronic kidney disease in the U.S. has markedly increased in recent years, along with increased rates of diabetes. According to the Center for Disease Control and Prevention (CDC), chronic kidney disease (CKD) is common in people with diabetes. Approximately 1 in 3 adults with diabetes has CKD, and any type (including type 1 and type 2 diabetes) can spur kidney disease. Less than 10% of patients with early-stage kidney disease are aware they have Chronic Kidney Disease (CKD)—knowledge is crucial because early intervention is…

China’s ‘monster drone’ TB-001 UAV spotted in ‘heavy bomber, missile truck’ mode

China’s Tengoen TB-001 drone was photographed recently carrying a full load of air-to-ground munitions of missiles and bombs, indicating the force-multiplier effect the Unmanned Combat Aerial Vehicle (UCAV) can have on the battlefield. The TB-001 is a Medium Altitude Long-Endurance (MALE) drone with three engines, first unveiled in September 2017 and has been in service with the People’s Liberation Army (PLA) since 2021. China presently has the most extensive and diverse range of drone systems, both stealth, non-stealth, jet-powered and propeller-driven, in the world.

Certain disease-causing pathogens are released when you flush toilets. This is how that affects you

Every time you flush a toilet, it releases plumes of tiny water droplets into the air around you. These droplets, called aerosol plumes, can spread pathogens from human waste and expose people in public restrooms to contagious diseases. Scientific understanding of the spread of aerosol plumes – and public awareness of their existence – has been hampered by the fact that they are normally invisible. My colleagues Aaron True, Karl Linden, Mark Hernandez, Lars Larson and Anna Pauls and I were able to use high-power lasers to illuminate these plumes, enabling us to image and measure the location and motion…

Nigerian start-up uses tech products to help the visually impaired

A Nigerian start up called Vinsighte is using technology to assist the visually impaired, with several products including "smart" reading glasses that convert text to audio. About 15.3% of the world's blind population resides in Africa, according to the World Health Organization, where they often lack the resources and support needed to succeed in school and everyday life. "I wanted to just try and see if we could build something that could solve the problem and that was where it all started," said Vinsighte CEO Kolawole Tomi. The company distributes its products to schools and institutions and estimates it has…

This drug costs $3.5m per dose. This is what it’s used for

U.S. health regulators on Tuesday approved the first gene therapy for hemophilia, a $3.5 million one-time treatment for the blood-clotting disorder. The Food and Drug Administration cleared Hemgenix, an IV treatment for adults with hemophilia B, the less common form of the genetic disorder which primarily affects men. Currently, patients receive frequent, expensive IVs of a protein that helps blood clot and prevent bleeding. Drugmaker CSL Behring, based in Pennsylvania, announced the $3.5 million price tag shortly after the FDA approval, saying its drug would ultimately reduce health care costs because patients would have fewer bleeding incidents and need fewer…

‘Impossible to intercept’: Russia shows how its Avangard Hypersonic Missile gets loaded

On November 18, the Russian Defense Ministry released a video showing how its Avangard Hypersonic Missile, which it claims is “impossible to intercept,” is loaded into the launch shaft. The Avangard is a hypersonic glide vehicle that entered service in December 2019. It can be fired by various ICBMs, including the country’s newest and most advanced intercontinental ballistic missile, the RS-28 Sarmat. In 2018, Russian President Vladimir Putin stated that the weapon can travel toward targets “like a meteorite, a fireball.” According to the Russian military, placing a rocket into the launcher is a skill. A loader removes the missile…
