Organic boronic acids are widely used as starting material in the synthesis of various useful chemicals. But, some organic boronic acids are unstable and lead to unwanted 'side reactions.' Thus, they need to be protected with a functional group, which needs to be removed afterwards. A research team recently uncovered how this unnecessary step (removal of the functional group) could be avoided — s
Biomedical engineers have demonstrated a lensless on-chip microscopy platform that eliminates several of the most common problems with conventional optical microscopy and provides a low-cost option for the diagnosis of disease.
After 50 years of research and the testing of over 1,000 drugs, there is new hope for preserving brain cells for a time after stroke. Treating acute ischemic stroke patients with an experimental neuroprotective drug, combined with a surgical procedure to remove the clot improves outcomes as shown by clinical trial results.
A team took a novel, interdisciplinary approach to analyzing the behavior of breast tumor cells by employing a statistical modeling technique more commonly used in physics and economics. The team was able to demonstrate how the diversity, or heterogeneity, of cancer cells can be influenced by their chemical environment — namely, by interactions with a specific protein, which leads to tumor growth
Several processes in the roundworm C. elegans boost the stress response in cells, incidentally making worms resistant to a high-fat diet and extending their lifespan. Researchers have found another: cells called glia that release a hormone that boosts the unfolded protein response in the endoplasmic reticulum of the worm's cells, effectively doubling lifespan. This could lead to interventions to t

The Northern European Enclosure Dam (NEED) would cut off the North and Baltic Seas from the Atlantic Ocean. It would save 15 countries, and up to 55 million people, from sea level rise—but at a cost. The idea is a warning more than a plan: NEED will be necessary if we don't stop global warming now. Unprecedented scale Climate change is real, and it's bad. It's also gradual and impersonal. That's
Minister says outbreaks has entered new phase but still hopeful of containing spread in epicentre of Daegu South Korea has reported another huge jump in cases of coronavirus as the country fights to contain the spread of the deadly disease. The number of infections has increased by 142 to 346, officials said on Saturday, with most of the cases linked to the city of Daegu and surrounding region tw
Case study of 20-year-old who infected relatives despite not showing signs of illness – and testing negative – stokes global pandemic fears A 20-year-old Chinese woman from Wuhan travelled hundreds of miles to another city where she is believed to have infected five relatives without showing signs of infection, scientists in China have said, offering fresh evidence that the new coronavirus can be

So I was having a drawn out discussion with some of my buddies online a few minutes ago, and we got to the topic of scientific progress, I brought up potential treatments for cancer, and possible methods of human colonization of space, and space travel in general. As a response they just laughed at me and started memeing about how unrealistic everything scientific is, from nuclear fusion, to adva

Production continues to climb and Tesla's total stock market value – the market cap – has passed $100 billion, making it the world's second most valuable car company after Toyota. It has already doubled in 2019. This after having sold a record 368,000 cars
There was a time—the 1990s—when the word alternative meant a lot in music. But what? The term came to encompass not only the conscientious angst of Nirvana but also that band's corporate knockoffs; not only the paranoia of Radiohead but also the treacle of Goo Goo Dolls; not only the quiet of Tori Amos but also the thunder of Deftones. Eventually the distinction between alternative and undergroun

For sheer political spectacle, encounters between Donald Trump and Narendra Modi are hard to top. Last fall in Houston, both leaders put on a show for a raucous crowd of 50,000. They clasped hands before the multitude, and lavished praise on each other. Their encore performance in Modi's home state of Gujarat, India, later this month will be worth the price of admission, with crowds as outsize as

It's 2020, and America is embroiled in not one but two catastrophic wars: one with Iran that has sucked in the entire Middle East, and another halfway across the world in North Korea sparked by Kim Jong Un test-firing nuclear-capable missiles that could hit the United States. It's all the worse since the U.S. is waging both wars without allies, all of which have abandoned Donald Trump because of
If Donald Trump is defeated in November 2020, his presidency will end on January 20, 2021. If he is reelected, then, barring other circumstances such as removal from office, his administration will terminate on the same day in 2025. In either of these scenarios, Trump would cease to be president immediately upon the expiration of his term. But what if he won't leave the White House? The American
