Bermuda Triangle mystery resolved?

A Science channel has reported that the mystery surrounding the Bermuda Triangle may have been solved.

The region is located near North America and has seen the disappearance of countless aeroplanes and ships.

According to a report, a group of scientists from the University of Colorado in the United States observed and studied the weather images, taken via satellite, where they saw unusual clouds over the region.

They claimed that the clouds are acting as “air bombs.”

It has been further mentioned that the wind speed can go above the 170 miles-per-hour mark and the waves can go over 45 ft. The report added that no ships or planes will be able to survive the wind force.

The Bermuda Triangle is unique as the clouds have straight edges.

The recent theory has laid the foundation for further investigation and research for solving the abnormalities surrounding the area.

Earlier, the wreckage of a coal ship that vanished in the Bermuda Triangle with 32 passengers onboard has been found by underwater explorers after nearly 100 years of its disappearance.

The steam-powered bulk carrier, SS Cotopaxi, set off for a journey from Charleston, South Carolina to Havana, Cuba and disappeared near Bermuda in 1925.

As usual, no one knew what happened to the ship or its crew as they were never found.

Instagram hits pause on kids version of app

Instagram is pausing work on a version for children younger than 13, called “Instagram Kids”, the Facebook-owned photo sharing app said on Monday.

Instagram Kids was touted to require parental permission to join, and provide ad-free, age-appropriate content, but US lawmakers and advocacy groups alike have urged the social media giant to drop its launch plans, citing safety concerns.

“We won’t stop pressuring Facebook until they permanently pull the plug,” said Josh Golin, executive director of Fairplay, an advocacy group focused on kids.

Instagram said in a blog post that building Instagram Kids was the right thing to do, but it was pausing the work and would continue building on its parental supervision tools.

“The reality is that kids are already online, and we believe that developing age-appropriate experiences designed specifically for them is far better for parents than where we are today,” it said.

The Wall Street Journal published a report earlier this month, focusing on data suggesting Instagram had a harmful effect on teenagers, particularly teen girls and that Facebook had made minimal efforts to address the issue. However, Facebook has said the report is inaccurate.

The social life of a vampire bat

When one thinks of vampire bats, friendship and cooperation may not be among the qualities that come to mind for these blood-feasting creatures of the night. But maybe they should.

Scientists have provided a deeper understanding of social relationships among vampire bats, showing how those that have forged bonds akin to “friendships” with others will rendezvous with these buddies while foraging for a meal.

Researchers attached small devices to 50 vampire bats to track nighttime foraging in Panama, when these flying mammals drink blood from wounds they inflict upon cattle in pastures. The study involved female bats, known to have stronger social relationships than males.

Among the bats were 23 wild-born individuals that had been kept in captivity for about two years during related research into bat social behavior. Social bonds already had been observed among some of them. After being released back into the wild, the bats were found to often join a “friend” during foraging, possibly coordinating the hunt.

“Each bat maintains its own network of close cooperative social bonds,” said behavioral ecologist Gerald Carter of the Ohio State University and the Smithsonian Tropical Research Institute, who led the research published in the journal PLoS Biology.

Social bonds among vampire bats as they roost in trees include grooming one another and regurgitating blood meals for hungry pals. The study showed that the social bonds formed in roosts extended into the hunt.

“This study opens up an exciting new window into the social lives of these animals,” Carter said.

The researchers suspect that the bats, while almost never departing on foraging forays with their “friends,” link up with them during the hunt – perhaps even recognizing one another’s vocalizations – for mutual benefit. They hypothesize the bats might exchange information about prey location or access to an open wound for feeding.

Vampire bats, which inhabit warmer regions of Latin America and boast wingspans of about 7 inches (18 cm), are the only mammals with a blood-only diet. They reside in colonies ranging from tens to thousands of individuals.

“People’s first reaction to vampire bats is usually, ‘Uh, scary.’ But once you tell them about their complex social lives, they are quite surprised that we can find such behavior that is somewhat similar to what humans do – and which one would maybe expect in primates – in bats,” said study co-author Simon Ripperger, a Smithsonian Tropical Research Institute post-doctoral researcher.

Ripperger called them “amazing creatures” for several reasons.

“Even besides their social lives, vampire bats are quite special: specializing in a diet of 100% blood is already quite rare among vertebrates,” Ripperger said. “They are amazing runners, which you wouldn’t expect in a bat. They have heat sensors in their snouts that help them find a spot to make a bite. They have a protein in their saliva that prevents blood from coagulation, which is actually being used in medical trials to help prevent blood clots in patients who suffered a stroke.”

The bats attack prey from the ground, using their sharp teeth to open a wound, lapping up blood with their tongues.

Carter said there is reason to fear vampire bats because they can transmit rabies to livestock and people.

“But I do think they are beautiful and interesting animals in their own right,” Carter added. “In this way they are a bit like grizzly bears, sharks, rats and venomous snakes: animals that might not help people in any way and might even endanger them, but should still be appreciated for their own sake.”

Study shows antibody growth from AstraZeneca, Sputnik Light COVID-19 vaccine mix

A small-scale clinical study of the combined use of the AstraZeneca and Sputnik Light vaccines against COVID-19 has shown strong antibody growth in a majority of the study’s participants, the Russian Direct Investment Fund said on Monday.

The data was collected from 20 people who took part in a 100-person study in Azerbaijan that began in February. They first received the AstraZeneca shot followed by the one-dose Russian-made Sputnik Light shot 29 days later, RDIF said.

“According to the results of the interim analysis, a fourfold or higher increase in neutralising antibodies to the spike protein (S-protein) of the SARS-CoV-2 was found in 85% of the volunteers on the 57th day of the study,” RDIF said.

Windows 11 gets an update for the better experience of Android users

Microsoft window 11

Your Phone software by Microsoft, which serves as a bridge between Android devices and Windows 10, is all set to get a makeover for Windows 11.

While things do not seem to have changed dramatically like new functionality is on the cards in the short term, we know a bit into the app at Microsoft’s recent Surface event as it still reminds us of its existence.

Your Phone app, too, gets a new look as do the other apps updated for Windows 11, with softer set of colors and rounded corners. However, it’s in the interface where the real improvement lies.

If you go into the app right now, you’ll see separate sections for Notifications, Messages, Calls. Also, Apps if you own a supported Samsung device or a Surface Duo. With the new version, XDA Developers spotted that notifications now feature along the left-hand side of the app, with can respond directly from your desktop or laptop.

Other items to have been relocated are Messages, Photos, Apps and Calls that now appear at the top of the screen. The now little less cluttered look should make the app a bit more accessible to newcomers. Although, it can be a bit confusing to those who have got used to the current layout.

From this brief glimpse it’s encouraging to see that the app hasn’t been forgotten about even if it doesn’t get so many changes, and while it’s understandably not as impressive as the synergy between iPhones and Macs (where things like iMessage and Photos are always in perfect sync), it’s still useful for those that spread their working life across form factors.

And with Microsoft fully on board with Android, having waved the white flag on Windows Phone some time ago, a lot more people can benefit.

Is it necessary?

Many have reportedly said they installed the Your Phone software for Windows 10 upon release, but haven’t booted it up again since. Why? Because the stuff they thought they needed it for already has perfectly good systems in place.

But for some it will prove invaluable, and that — combined with the upcoming Android app support for Windows 11 — makes Microsoft’s OS a natural home for Android users.

Microsoft Windows 11 will be released on October 5 as a free upgrade to Windows 10, but the rollout is going to be staggered, so don’t expect to see it on your screen immediately unless you buy a new device — such as Microsoft’s own Surface Pro 8, Surface Pro X, Surface Go 3 or the innovative new Surface Laptop Studio.

WhatsApp will stop working on some Android phones

Another year is about to end in the next three months, which means there is another cycle of WhatsApp’s end of support for some Android smartphones and iPhones. After November 1, 2021, the messaging app will not work on some of the Android versions. 

WhatsApp is used to removing the support for specific Android versions. This is a common technique because developers always prefer to support the newest OS updates, and it’s hard to always support old versions. It’s the case of Android OS 4.0.4 and older versions: WhatsApp has announced that they will no longer support Android phones running those versions after a new WhatsApp beta for Android update.

What can you do to continue using WhatsApp on those versions? Unfortunately, you won’t be able to update WhatsApp after November 1, 2021, and your current WhatsApp update is going to expire after a certain date.

You need to switch to a new Android device on a supported Android version if your device is old, so be sure to back up your chat history. Note that WhatsApp is also going to support chat history migration from Android to iOS in a future update if you’re interested to switch to iPhone.

How a plant virus could help stop cancers from reaching the lungs

Using a virus that grows in black-eyed pea plants, nanoengineers at the University of California San Diego developed a new treatment that could keep metastatic cancers at bay from the lungs.

The treatment not only slowed tumor growth in the lungs of mice with either metastatic breast cancer or melanoma, it also prevented or drastically minimized the spread of these cancers to the lungs of healthy mice that were challenged with the disease.

The research was published Sept. 14 in the journal Advanced Science.

Cancer spread to the lungs is one of the most common forms of metastasis in various cancers. Once there, it is extremely deadly and difficult to treat.

Researchers at the UC San Diego Jacobs School of Engineering developed an experimental treatment that combats this spread. It involves a bodily injection of a plant virus called the cowpea mosaic virus. The virus is harmless to animals and humans, but it still registers as a foreign invader, thus triggering an immune response that could make the body more effective at fighting cancer.

The idea is to use the plant virus to help the body’s immune system recognize and destroy cancer cells in the lungs. The virus itself is not infectious in our bodies, but it has all these danger signals that alarm immune cells to go into attack mode and search for a pathogen, said Nicole Steinmetz, professor of nanoengineering at UC San Diego and director of the university’s Center for Nano-ImmunoEngineering.

To draw this immune response to lung tumors, Steinmetz’s lab engineered nanoparticles made from the cowpea mosaic virus to target a protein in the lungs. The protein, called S100A9, is expressed and secreted by immune cells that help fight infection in the lungs. And there is another reason that motivated Steinmetz’s team to target this protein: overexpression of S100A9 has been observed to play a role in tumor growth and spread.

“For our immunotherapy to work in the setting of lung metastasis, we need to target our nanoparticles to the lung,” said Steinmetz. “Therefore, we created these plant virus nanoparticles to home in on the lungs by making use of S100A9 as the target protein. Within the lung, the nanoparticles recruit immune cells so that the tumors don’t take.”

“Because these nanoparticles tend to localize in the lungs, they can change the tumor microenvironment there to become more adept at fighting off cancer — not just established tumors, but future tumors as well,” said Eric Chung, a bioengineering Ph.D. student in Steinmetz’s lab who is one of the co-first authors on the paper.

To make the nanoparticles, the researchers grew black-eyed pea plants in the lab, infected them with cowpea mosaic virus, and harvested the virus in the form of ball-shaped nanoparticles. They then attached S100A9-targeting molecules to the surfaces of the particles.

The researchers performed both prevention and treatment studies. In the prevention studies, they first injected the plant virus nanoparticles into the bloodstreams of healthy mice, and then later injected either triple negative breast cancer or melanoma cells in these mice. Treated mice showed a dramatic reduction in the cancers spreading to their lungs compared to untreated mice.

In the treatment studies, the researchers administered the nanoparticles to mice with metastatic tumor in their lungs. These mice exhibited smaller lung tumors and survived longer than untreated mice.

What’s remarkable about these results, the researchers point out, is that they show efficacy against extremely aggressive cancer cell lines. “So any change in survival or lung metastasis is pretty striking,” said Chung. “And the fact that we get the level of prevention that we do is really, really amazing.”

Steinmetz envisions that such a treatment could be especially helpful to patients after they have had a cancerous tumor removed. “It wouldn’t be meant as an injection that’s given to everyone to prevent lung tumors. Rather, it would be given to patients who are at high risk of their tumors growing back as a metastatic disease, which often manifests in the lung. This would offer their lungs protection against cancer metastasis,” she said.

Before the new treatment can reach that stage, the researchers need to do more detailed immunotoxicity and pharmacology studies. Future studies will also explore combining this with other treatments such as chemotherapy, checkpoint drugs or radiation.

Paper: “S100A9-Targeted Cowpea Mosaic Virus as a Prophylactic and Therapeutic Immunotherapy Against Metastatic Breast Cancer and Melanoma.” In addition to Young Hun (Eric) Chung, co-first authors of the study include Jooneon Park and Hui Cai. Nicole Steinmetz serves as the corresponding author of this work.

New tech to prevent Li-ion battery fires

Materials scientists from Nanyang Technological University Singapore have found a way to prevent internal short-circuits, the main cause of fires in Li-ion batteries.

Billions of Li-ion batteries are produced annually for use in mobile phones, laptops, personal mobile devices, and the huge battery packs of electric vehicles and aircraft.

This global battery demand is set to grow, with electric vehicles alone requiring up to 2,700 GWh worth of Li-ion batteries a year by 2030, equivalent to some 225 billion mobile phone batteries.

Even with an estimated failure rate of less than one-in-a-million, in 2020 there were 26 power-assisted bicycle (PAB) fires and 42 cases of personal mobility device fires in Singapore.

In most Li-ion battery fires, the cause is due to a build-up of lithium deposits known as dendrites (tiny wire-like tendrils) that cross the separator between the positive (cathode) and negative (anode) electrodes of the battery when it is being charged, causing a short-circuit leading to an uncontrolled chemical fire.

To prevent such battery fires, NTU scientists invented a patent-pending “anti-short layer” that can be easily added inside a Li-ion battery, preventing any future short-circuits from occurring during the charging process.

This concept is akin to adding a slice of cheese to a hamburger’s meat patty in between the buns, thus the new “anti-short layer” can be rapidly adopted in current battery manufacturing.
