AI ‘voice cloning’ scams are on the rise. Here’s how to protect yourself

Voice cloning scams are AI-driven frauds where criminals use short audio samples to create an accurate replica of a person’s voice to trick the receiver into transferring money to an untraceable account or handing out cash. Scammers steal voice samples from SNS, YouTube, or voicemail greetings and feed them into AI software to replicate their speech. They use voice skinning to manipulate their voice or text-to-speech tools to make them sound like the person they are mimicking in real time. Also, fraudsters might make the call appear as if it is coming from a known number. Because such calls have become too hard to determine their authenticity, it is advised to look for signs of fraud, such as a sense of urgency or deadline, confidentiality, and the amount of money. Will AI technologies or our smartphones detect AI-generated scams and protect us from fraudsters?

'Mornings and nights no longer exist' at 47C: A day in the hottest place in India

Banda District in Uttar Pradesh, India, sits near the Tropic of Cancer, where the Sun appears directly overhead during the summer solstice. In late May, the hottest month of the region, temperatures of 47-49C continued for nearly 10 days there. Around two million live in the broader Banda, many of whom work outdoors, such as farming, construction, and transport. People start working before sunrise, take a break indoors between noon and around 4 pm, and then resume their work until 7 pm, working for the same hours while enduring the heat. Indeed, they have little or no option but to live with the heat. And the situation has become more intolerable in the last few years as the tree cover has fallen for farming and mining, and sand mining and groundwater depletion have weakened the cooling mechanism in the surrounding landscape. In fact, Banda is part of the Indo-Gangetic Plain, which is regarded as one of the world’s emerging hotspots for dangerous humid heat. It is becoming hotter for longer, and the landscape is losing more trees and water, unendurable conditions for residents, especially for children and elderly people who are vulnerable to extreme heat. Not air conditioning, but trees, shade, and water are more sustainable means for mitigating the heat in Banda.

Dear MEL Topic Readers, 

Brain freeze? Ice cream headaches can reveal a surprising amount about your health

When you sip, lick, or bite a cold substance, such as an ice cube, shaved ice, or ice cream, you might feel an acute ache in your forehead. This cold-stimulus headache occurs when the roof of the mouth or back of the throat is cooled so rapidly that it shrinks the blood vessels, and then the shrunk vessels are forced to swell back up again to restore blood flow. This rapid change in the blood flow activates pain receptors and sends signals to the brain, but the brain misinterprets them as coming from the forehead rather than the mouth. That’s why your forehead hurts but not your tongue. It is easily avoidable if you take a little more time to eat or drink cold food or drinks. But some people still experience a more severe headache than others. Researchers think this blood vessel shrinkage seems to run in families. Do your parents have ice cream headaches, too? Also, those who have migraine tend to experience this kind of headache when they eat cold stuff. So, if you feel pain in your brain or forehead when you eat ice cream even if you’ve eaten it slowly, you may want to try the same treatment as for migraine. An ice cream headache can be mostly prevented or eased if you take a little more time to enjoy the cold treat.

Read the article and learn why you may experience a headache when you eat ice cream.

The arteries of modern civilization: The US and allies take action to protect seabed cables

Where do you think the vast amount of data is being transmitted every day and every second? Most of the world’s intercontinental data, including payments, trade, and data flows, travels through 570 existing and 80 planned undersea internet cables, the arteries of modern civilization. However, just like underwater gas pipelines, they are so vulnerable to attacks because they have no defense mechanisms or forces. In fact, several incidents of damage to internet cables and gas pipelines have been reported in the Baltic Sea since Russia’s full-scale invasion of Ukraine. Just like the blockage of the Strait of Hormuz has created global oil shortages, disruptions to underwater pipelines and cables could cause regional and global nightmares. Recently, Australia, the UK, and the US (AUKUS) have reached a trilateral defense pact to improve reconnaissance and strike capabilities. Since data centers are being built around the world and are connected to each other, protecting the data arteries plays a vital role in ensuring smooth data transmissions and internet connections.

Why America’s rich keep getting richer

In the “K-shaped economy”, the upper arm of the letter “K” represents the wealthy while the lower arm shows lower-to-middle-income families. In the last three years in the US, the top 1% earners increased their cumulative real net worth by 30%, the next 19% earners gained 20%, and the next 20%, classified as the upper middle group, enjoyed about an 18% increase (Vol 5152), while the middle 40% and bottom 20% had less than a 15% gain. What made the gap wider between those who gained wealth more and less is housing, stocks, and inflation. Even though the S&P 500, the benchmark market index, has gained 86% over the last three years, about three-quarters of America’s stocks are owned by the top 20% earners. As for housing, over half of mortgages belong to the top 20%, whose property values have seen steep increases in the last few years. In the meantime, recent inflation in food, energy, and gas prices, in particular, hit the middle 40% and bottom 20% of income groups harder because they spend a higher proportion of their income on those daily necessities. Once dreamed of by middle-income households were cars and houses, which are now getting out of their reach. How will AI affect the wealth gap for Americans?

Protect yourself from contagious viruses (and we don’t mean Ebola), with these expert tips

The FIFA World Cup kicks off next week in the US, Canada, and Mexico, and millions of fans will scream germs into the air of very crowded stadiums. Also, summer vacationers are traveling around and interacting with others in many ways. In the meantime, the hantavirus outbreak on a Dutch cruise ship in April infected 13 on board and killed three. Also, the Ebola outbreak in Central Africa has infected hundreds and killed more than 200, and is still active. Contagious diseases can be easily transmitted from one person (or animal) to another through various routes, including airborne/respiratory droplets, physical contact, or fecally or orally contaminated surfaces. One of the most worrisome contagious viruses is measles, whose particles can stay in the air for up to two hours. It is much more contagious than the flu or COVID-19, as a single infected individual could pass the virus to between 12 and 18 people. The problem is that even though it can be contained by a simple vaccine, vaccination rates for measles are falling in many countries, including the World Cup host countries. How can you better protect yourself from viruses besides vaccination?

Dear MEL Topic Readers, 

Is 'out of control' US tipping culture spreading overseas?

In the US, tipping is a standard practice for services such as restaurants, taxis and rideshares, doormen and bellboys, and delivery services. Among these, servers at restaurants depend most of their income on tips from their customers because their minimum hourly wage is set significantly lower than the federal minimum wage. The expected restaurant tip in the US was 10% to 15% of the bill in the mid to late 20th century, but it has risen to 18% or higher today, partly due to pre-programmed electronic payment machines that often suggest 18%, 20%, 22%, and 25%. In large cities like New York, Chicago, and Los Angeles, a 20% tip is mostly expected. Tipping/gratuity is a unique practice in the USA, and it is not expected in most other countries. However, when American travelers dine in restaurants abroad, they often leave tips for their servers. This has made serving staff expect tips from other customers, too, which makes locals annoyed. Another influencer of tipping practice is rideshare services, like Uber, which also show tipping options in other countries where they operate. If you travel abroad, you may want to ask AI if you should leave tips, where, to whom, and how much in advance.

Read the article and learn about how tipping is practiced in the USA and other countries.
