A Law Professor Explains How Blockchains And NFTs Don’t Protect Virtual Property – Can You Truly Own Anything In The Metaverse?

In 2021, an investment firm bought 2,000 acres of real estate for about US$4 million. Normally this would not make headlines, but in this case the land was virtual. It existed only in a metaverse platform called The Sandbox. By buying 792 non-fungible tokens on the Ethereum blockchain, the firm then owned the equivalent of 1,200 city blocks. But did it? It turns out that legal ownership in the metaverse is not that simple. The prevailing but legally problematic narrative among crypto enthusiasts is that NFTs allow true ownership of digital items in the metaverse for two reasons: decentralization and interoperability. These two technological features have led some to claim that tokens provide indisputable proof of ownership, which can be used across various metaverse apps, environments an...

A Finance Expert Explains The ‘Poison Pill’ The Anti-Takeover Tool That Twitter Hopes Will Keep Elon Musk At Bay

Takeovers are usually friendly affairs. Corporate executives engage in top-secret talks, with one company or group of investors making a bid for another business. After some negotiating, the companies engaged in the merger or acquisition announce a deal has been struck. But other takeovers are more hostile in nature. Not every company wants to be taken over. This is the case with Elon Musk’s US$43 billion bid to buy Twitter. Companies have various measures in their arsenal to ward off such unwanted advances. One of the most effective anti-takeover measures is the shareholder rights plan, also more aptly known as a “poison pill.” It is designed to block an investor from accumulating a majority stake in a company. Twitter adopted a poison pill plan on April 15, 2022, shortly after Musk un...

A Computer Scientist Explains – Why ‘Bad’ Ads Appear On ‘Good’ Websites

Sketchy ads, like those for miracle weight loss pills and suspicious-looking software, sometimes appear on legitimate, well-regarded websites. It turns out that most websites don’t actually decide who gets to show ads to their viewers. Instead, most sites outsource this task to a complex network of advertising tech companies that do the work of figuring out which ads are shown to each particular person. The online ad ecosystem is largely built around “programmatic advertising,” a system for placing advertisements from millions of advertisers on millions of websites. The system uses computers to automate bidding by advertisers on available ad spaces, often with transactions occurring faster than would be possible manually. Programmatic advertising is a powerful tool that allows advertiser...

Whats Good: Sugar Detox? Cutting Carbs? A Doctor Explains Why You Should Keep Fruit On The Menu

One of my patients – who had been struggling with obesity, uncontrolled diabetes and the cost of her medications – agreed in June 2019 to adopt a more whole-food plant-based diet. Excited by the challenge, she did a remarkable job. She increased her fresh fruit and vegetable intake, stopped eating candy, cookies and cakes and cut down on foods from animal sources. Over six months, she lost 19 pounds and her HbA1c – a measure of her average blood sugar – dropped from 11.5% to 7.6%. She was doing so well, I expected that her HbA1c would continue to drop and she would be one of our plant-based successes who had reversed diabetes. Her three-month follow-up visit in March 2020 was canceled because of COVID-19 lockdowns. When I eventually saw her again in May 2021, she’d regained some of the ...

An Expert Explains What Aphasia Is – The Condition Forcing Bruce Willis To Retire From Acting

Actor Bruce Willis, 67, is “stepping away” from his career in film and TV after being diagnosed with aphasia, his family announced on March 30, 2022. In a message posted on Instagram, his daughter, Rumer Willis, said that the condition was “impacting his cognitive abilities.” Swathi Kiran, director of the Aphasia Research Laboratory at Boston University, explains what aphasia is and how it impairs the communication of those with the condition. What is aphasia? Aphasia is a communication disorder that affects someone’s ability to speak or understand speech. It also impacts how they understand written words and their ability to read and to write. It is important to note that aphasia can take different forms. Some people with aphasia only have difficulty understanding language – a result o...

An Electrical Engineer Explains How A Large Solar Storm Could Knock Out The Power Grid And The Internet

On Sept. 1 and 2, 1859, telegraph systems around the world failed catastrophically. The operators of the telegraphs reported receiving electrical shocks, telegraph paper catching fire, and being able to operate equipment with batteries disconnected. During the evenings, the aurora borealis, more commonly known as the northern lights, could be seen as far south as Colombia. Typically, these lights are only visible at higher latitudes, in northern Canada, Scandinavia and Siberia. What the world experienced that day, now known as the Carrington Event, was a massive geomagnetic storm. These storms occur when a large bubble of superheated gas called plasma is ejected from the surface of the sun and hits the Earth. This bubble is known as a coronal mass ejection. The plasma of a coronal mass e...

A Neurologist Explains – Why Daylight Saving Time Is Unhealthy

As people in the U.S. prepare to turn their clocks ahead one hour in mid-March, I find myself bracing for the annual ritual of media stories about the disruptions to daily routines caused by switching from standard time to daylight saving time. About a third of Americans say they don’t look forward to these twice-yearly time changes. An overwhelming 63% to 16% majority would like to eliminate them completely. But the effects go beyond simple inconvenience. Researchers are discovering that “springing ahead” each March is connected with serious negative health effects. I’m a professor of neurology and pediatrics at Vanderbilt University Medical Center in Nashville, Tennessee, and the director of our sleep division. In a 2020 commentary for the journal JAMA Neurology, my co-authors and I r...

A Bioethicist Explains Why Restricting Opioid Supply May Not Be The Right Solution For Opioid Overdose

Year after year, America’s drug overdose crisis is worsening. In the 12-month period ending in June 2021, the most recent period for which there is reliable data, more than 101,000 people died from drug overdose in the U.S., – an increase of more than 20% from the previous year. 2021 was also an important year for analysis of the overdose crisis, with numerous books and articles shedding light on both the causes and potential solutions to the crisis. Not all analysis is in agreement, however. As a bioethicist who has spent much of the past several years researching the ethical and policy issues related to drug use, I’ve become particularly interested in an evolving tension between commentators on the drug crisis. While many blame today’s crisis on an increase in drug supply over the pa...

An Electrical Engineer Explains – How 5G Puts Airplanes At Risk

New high-speed cellphone services have raised concerns of interference with aircraft operations, particularly as aircraft are landing at airports. The Federal Aviation Administration has assured Americans that most commercial aircraft are safe, and AT&T and Verizon have agreed to hold off on installing their new cellphone antennas near airports for six months. But the problem has not been entirely resolved. Concerns began when the U.S. government auctioned part of the C-band spectrum to wireless carriers in 2021 for US$81 billion. The carriers are using C-band spectrum to provide 5G service at full speed, 10 times the speed of 4G networks. The C-band spectrum is close to the frequencies used by key electronics that aircraft rely on to land safely. Here’s why that can be a problem. Ke...

An Agriculture Expert Explains What Bio-engineered Food Is

The U.S. Department of Agriculture defines bioengineered food as food that “contains detectable genetic material that has been modified through certain lab techniques that cannot be created through conventional breeding or found in nature.” If that definition sounds familiar, it is because it is essentially how genetically modified organisms, or GMOs, are defined – common vocabulary many people use and understand. On Jan. 1, 2022, the USDA implemented a new U.S. bioengineered food disclosure standard. Shoppers are seeing labels on food products with the terms “bioengineered” or “derived from bioengineering” printed on a green seal with the sun shining down on cropland. More than 90% of U.S.-grown corn, soybeans and sugar beets are genetically modified. This means that many processed foo...
