Researchers Use Lasers to Bring the Internet Under the Sea

The system which they call Aqua-Fi, uses a combination of lasers and off-the-shelf components to create a bi-directional wireless connection for underwater devices. The system is fully compliant with IEEE 802.11 wireless standards, meaning it can easily connect to and function as part of the broader Internet. A big problem that needs to be addressed in order to make a system like Aqua-Fi commercially viable; because lasers are so precise, even mildly turbulent waters can knock a beam off course and cause it to miss a receptor. This could help companies like Microsoft who are exploring the possibility of placing data centers offshore and underwater.

Electrify Americaโ€™s first cross-country EV charging route is complete

Taking a cross-country roadtrip in your electric vehicle is a little more feasible thanks to Electrify America. Its first coast to coast EV fast charging route is now complete, and the company plans to have another route finished by September. The routes provide high-powered chargers to all EV brands, and on average, the stations are spaced about 70 miles apart, so EV owners can travel beyond a single charge without being stranded. The first route stretches over 2,700 miles from Washington DC to Los Angeles. The second route will connect Jacksonville and San Diego.

Reducing the Damage of a Heart Attack

Researchers have discovered how one key protein in the heart can reduce damage from the attack. MANF (mesencephalic astrocyte-derived neurotrophic factor) acts much like an automobile collision specialist, correcting other proteins that have misfolded. The initial oxidative stress after a heart attackโ€”the overabundance of oxygenโ€”is followed by a potentially damaging opposite effect where oxygen is used by the heart so quickly that it can become depleted. They found MANF decreased reductive stress-induced damage in mice could lead to the protein being administered as a drug that can be given to heart attack victims intravenously by first responders.

Sleeping with a partner affects your sleep cycle in one striking way

In a sample of 12 heterosexual couples who have been a couple for an average of 23.5 years, scientists found that sleeping together was linked to 10 percent more REM sleep compared to sleeping apart. During REM sleep, processes like dreaming and memory consolidation kick into gear. When partners slept apart they spent about 36.6 percent of the night, moving through sleep stages at the same time. Because all humans cycle through sleep stages, that’s not especially surprising โ€” there’s naturally going to be a little overlap. What’s notable is that this overlap significantly increased when the couples slept together, growing to 46.9 percent.

Huawei to build $1.2 billion Cambridge facility as it faces uncertain UK future

Huawei received approval to build a $1.25 billion research facility in the United Kingdom. The announcement comes as the United Kingdom is scrutinizing the Chinese telecom company’s involvement in the country’s 5G networks. The nine-acre facility in Cambridge will become the international headquarters of Huawei’s fiber optic communication business and create around 400 jobs, Huawei said in a press release. Vice President Victor Zhang touted what the new campus would do for the UK economy, saying it wants “to help enshrine the UK’s leading position in optoelectronics and promote UK tech on a global scale.”

GNC files for bankruptcy and will close up to 1,200 stores

GNC has filed for bankruptcy, warning it will close up to a quarter of its stores and search for a buyer. The 85-year-old vitamin and dietary supplement company has been saddled with nearly $1 billion of debt and has faced declining sales at its brick-and-mortar locations since before the pandemic. GNC will continue operating, but it will become a smaller company. It plans to close up to 20% of its 5,800 retail stores, which amounts to as many as 1,200 locations across the United States. It obtained $130 million in fresh financing from its largest vendor, vitamin supplier IVC, to help it restructure. GNC aims to emerge from bankruptcy in the fall.

Nearly $1.4 Billion In Coronavirus Relief Payments Sent To Dead People

The IRS sent nearly $1.4 billion in coronavirus relief payments to dead Americans, a new report by an independent government agency shows. The Government Accountability Office (GAO) said the error involved almost 1.1 million checks and direct deposits sent to ineligible Americans. The improper payments happened due to confusion over whether dead people should receive payments. The IRS actually had developed a process in 2013 to use death records to prevent improper payments to dead people however it bypassed these controls for coronavirus relief payments, the GAO found.

Three men arrested in Iran for allegedly selling babies on Instagram

Iranian authorities have arrested three men attempting to sell babies online. A 20-day-old baby and a two-month-old child were rescued from the online infant-selling ring. One was being advertised for 400 million Iranian Riyals ($9,490), and the other for 500 million Iranian Riyals ($11,800), according to KhabarOnline. Iran is among 21 “Tier Three” countries in the US State Department’s annual Trafficking in Persons Report which means they do “not fully meet the minimum standards for the elimination of trafficking and (are) not making any efforts to do so.”
