Mechanical and Computer Science remains the top priorities of engineering students. Today Digital Electronics goes very fast in daily life. Every buddy use the digital devices for their personal and business use and also for making the communication channels. This book gives the information about the various digital electronics devices and their use in details. Some UCLA wireless initiatives are already changing lives. About three years ago, Maxim Batalin, associate director of UCLA Engineering’s Institute for Technology Advancement, created an app for off-the-shelf heart monitoring devices that could remotely chart the activity and stress levels of emergency responders, who carry a high risk of heart attack due to their professions. All of these technological advances have led to the average computer user being able to access millions of bytes of information ready to be downloaded at their fingertips. Video and audio data files that once took hours to download now … Read the rest


The simple blood test has been described as a ‘game-changer’ (Credits: Getty Images/iStockphoto)

A blood test that may be able to spot more than 50 types of cancer will be piloted by the NHS, chief executive Sir Simon Stevens has announced.

The Galleri blood test, which can detect early stage cancers through a simple blood test, will be piloted with 165,000 patients in a deal struck by NHS England.

NHS England said research on patients with signs of cancer suggests the test can identify many types that are difficult to diagnose early, such as head and neck, ovarian, pancreatic, oesophageal and some blood cancers.

Developed by US-based company Grail, the test checks for molecular changes.

If the programme shows that the test also works as expected for people without symptoms, it will be rolled out to become routinely available.

The test could help meet the NHS goal of increasing the … Read the rest

  • SpaceX gained regulatory approval to offer its high-speed internet service, Starlink, in Canada.
  • The company hopes to provide high-speed data service to individuals in areas where it just hasn’t been available before.
  • In the United States and Canada, rural customers are often left with few or no options for high-speed internet service.

SpaceX’s Starlink satellite-based internet service aims to provide high-speed data to places where it just wasn’t available previously, and the company just took a big step toward that goal. The company has reportedly gained regulatory approval from Canada’s Innovation, Science and Economic Development Ministry. With that red tape out of the way, the company is free to offer its service in the country when it’s ready.

Starlink has gained a lot of attention in the United States as a potential alternative to high-priced cable internet providers, but its aim, at least at first, will be to provide … Read the rest


Julia Borges was at her cousin’s 12th birthday party when she was shot. The 17-year-old had been standing on a third-floor balcony when a stray bullet hit her in the back, lodging in the muscle between her lungs and aorta.

That was November 8. Luckily, Borges was taken to hospital and has since recovered. Many are not so fortunate. At least 106 people have been killed by stray bullets in Rio this year so far.

Among the most dangerous areas are the narrow streets of the city’s favelas, where more than a million people currently live. Here, the houses are piled up on each other, and the alleys that wind between them are dotted with small squares. These same streets regularly echo with the sounds of gunfire: shooutouts between police and drug traffickers, rival groups of traffickers, or even police-backed militias take place on a daily basis.

Innocent victims are often caught … Read the rest


Longtime Stitch Fix executive Mike Smith. | Stitch Fix

Stitch Fix’s Mike Smith is leaving the online apparel retailer.

Mike Smith is a versatile and well-respected executive in the e-commerce industry. He also happens to one of the few Black C-level leaders in tech.

Now he wants to play a bigger role in changing that.

Smith has served as president, COO, and interim CFO over eight-plus years at Stitch Fix, the online apparel retailer and personal styling service. But he told Recode on Thursday that he plans to leave his executive role at the $4 billion publicly traded company in the coming months to start a venture capital firm. His goal is to get more money into the hands of tech entrepreneurs from underrepresented backgrounds, namely Black, Latinx, and women founders.

Sitting at a laptop all day may be good for your job, but not for your health (Credits: Getty Images)

Working from home during the pandemic means many of us may be getting even less exercise than before.

There’s no more walking to the office, or running to catch a train or a bus. The lunchtime stroll may have vanished and getting to the gym is out of the question at the moment.

Sadly, the sedentary lifestyles of many officer workers – whether at a corporate or home office – is having an impact on our physical health.

Exceeding weekly recommended physical activity levels could ‘offset’ the harms caused by prolonged sitting, the World Heath Organisation (WHO) has now said.

Its recommendation, published in a special issue of the British Journal of Sports Medicine, is part of the new global guidelines on physical activity and sedentary behaviour.

Patients will also get support to increase their exercise levels

The recommendation from

Astronaut Scott Kelly famously lived and worked on the International Space Station for 340 days—the longest time an American has spent in space. His mission gave scientists some vital insight into what happens to the human body during long-duration stays in orbit. That’s because Kelly has an identical twin, Mark (also an astronaut, and now soon to be a US senator). The Kelly twins offered scientists a rare opportunity: as they studied what happened to Scott’s body during his year in space, they had the benefit of a control subject, Mark, who stayed on Earth.

The NASA Twins Study provided more evidence for what we already suspected. In a confined capsule under microgravity and prolonged exposure to radiation, the immune system takes a hit, the eye changes shape for the worse, and there’s some significant loss in muscle and bone mass.

But we also learned about some surprising effects. Kelly … Read the rest
