Physicists nudge atoms within less than a trillionth of a second

Scientists from Regensburg and Zurich have found a fascinating way to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second. The extremely sharp needle of their unique ultrafast microscope serves as the technical basis: It carefully scans molecules, similar to a record player. Physicists at the University...

CDC tells health officials to expect a coronavirus vaccine by November

Critics fear its development has become politicized by Trump who may push for the release of a vaccine that is not fully testedHealth officials across the US have reportedly been notified that they should expect a coronavirus vaccine available to health workers and high-risk groups by November, amid concerns the accelerated vaccine development process has become politicized.The Centers for Disease...

'It just sounds like a thud': astronomers hear biggest cosmic event since big bang

Researchers believe noise was two black holes colliding around 7 billion years ago, creating a previously unseen class of stellar objectScientists have announced the detection of a signal from a long-ago collision between two black holes that created a new one of a size never seen before.“It’s the biggest bang since the big bang observed by humanity,” said Caltech physicist Alan Weinstein,...

Links among poor sleep, high blood pressure, gut microbiome discovered

Researchers have found associations among disrupted sleep, elevated blood pressure and changes in the gut microbiome. The research aimed to determine whether a 28-day period of disrupted sleep changed the microbiota in rats. The researchers also sought to identify biological features associated with undesirable arterial blood pressure changes.

How mechanical forces nudge tumors toward malignancy

Researchers studying two forms of skin cancer identified a long-overlooked factor determining why some tumors are more likely to metastasize than others: the physical properties of the tissue in which the cancer originates. The findings might set the stage for new ways to monitor and treat the diseases in the future.

New treatment for drug-resistant bacterial infections

A new antibacterial agent that has been engineered to essentially hide from the human immune system may treat life-threatening MRSA infections. A new article provides details on the agent, which is the first lysin-based treatment with the potential to be used multiple times on a single patient, making it ideal to treat particularly persistent drug-resistant and drug-sensitive infections.

Newly identified gene grants tomatoes resistance to bacterial speck disease

Bacterial speck disease, which reduces both fruit yield and quality, has been a growing problem in tomatoes over the last five years. Because the culpable bacterium, Pseudomonas syringae, prefers a cool and wet climate, crops in places such as New York State have been particularly susceptible. Researchers have uncovered the first known gene to impart resistance to a particular strain of the...

Many forests scorched by wildfire won't bounce back

A study of 22 burned areas across the Southern Rocky Mountains found that forests are becoming less resilient to fire, with some converting to grasslands after burning. By 2050, as little as 3.5% to 6.3% of Douglas fir and ponderosa pine forests in the region will be suitable for recovery post-fire, the study found.

Nasal swab followed by antibody test may catch incorrect Covid-19 diagnoses

Use of dual testing could help as swabs miss around 30%-50% of infections, say UK researchersCoronavirus – latest updatesSee all our coronavirus coverageTesting people twice for the coronavirus, with a nasal swab followed by an antibody finger prick test, would catch most of those people who fail to get the right Covid-19 diagnosis, researchers believe.Nose and throat swabs miss around 30% to...

Exclusive: Brazil Amazon fires likely worst in 10 years, August data incomplete, government researcher says

The official August data on the number of fires in Brazil's Amazon needs to be corrected and will likely show an increase over last year, meaning that blazes surged to a decade high, a scientist responsible for the figures told Reuters on Wednesday. Brazilian media has reported that fires in Brazil's section of the Amazon rainforest fell by 5% in August, citing data currently on the website of...

AI Advances and Applications

Is AI at an impasse? The growth of AI to date has been fueled by massive amounts of data and exponential gains in processing efficiency. But are these gains sustainable and if not, what is going to take us to the next level?  Join us virtually at EmTech MIT as we look at the status quo and the road ahead for AI. We’ll examine how today’s AI tools are being used to solve real-world...
