Oumuamua is an interstellar object that reached the solar system two years back. It showed unusual acceleration in its course across space, which led scientists to believe it could be a probe from another planet or even extraterrestrials. What it is.

Why it’s important

Oumuamua, from the very first day of its discovery, literally perplexed scientists, as it showed an unusual acceleration in its course across space. Now, in a new study report published in The Astrophysical Journal Letters, Loeb and Thiem Hoang, an astrophysicist at the Korea Astronomy and Space Science Institute, has claimed that the hydrogen hypothesis will not work in the real world, which means there could be still a scope that advanced aliens from deep space might have visited the solar system.

It was around two years back that space scientists discovered Oumuamua, an interstellar object that reached the solar system. Oumuamua, from the very first day of its discovery, literally perplexed scientists, as it showed an unusual acceleration in its course across space. After observing this unusual acceleration, Avi Loeb, of the Harvard University suggested that Oumuamua could be an alien probe.

Oumuamua Mystery Continues

However, most of the other space scientists dismissed the claims made by Loeb, and they made it clear that Oumuamua’s acceleration might be likely due to a natural process. In a study report published in June, researchers noted that solid hydrogen was blasting invisibly off Oumuamua’s surface, and this phenomenon could be causing the unexpected acceleration.

Air conditioners are a convenient way to cool down offices and homes, but they use huge amounts of energy in the process. A team of scientists has been developing an alternative solution for those warm summer months called the Cold Tube, which works by absorbing body heat emitted from a person and can use around half the energy of traditional systems as a result.

The notoriously bad energy efficiency of air conditioners has motivated the development a range of environmentally friendly solutions, from attachments that use water mist to pre-cool the units to solar-powered systems that produce hot water at the same time. In 2018, Richard Branson even launched a US$3 million competition aimed at developing more energy efficient air conditioners.

Similarly, the research team behind the Cold Tube has been investigating next-generation systems that keep people cool in more efficient ways. Made up of scientists from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre, the team took aim at the dehumidification process that is a critical function of today’s air conditioning systems.

Editor’s note: A recording of this virtual event is embedded above.

Artificial intelligence is proving a potent weapon against the pandemic, enabling researchers to comb through massive data sets to understand the virus and how to combat it. From drug development to immune response, STAT’s Casey Ross will talk to researchers and AI experts about how AI is accelerating a worldwide effort to crack Covid-19’s molecular code.

Most of us are now familiar with apps that track what’s known as our ‘digital biomarkers’. These include the steps, we’ve taken, our heart rate, and our weight. In recent years startups have appeared which can, in a relatively turnkey manner, track our ‘biomedical markers’, such as cholesterol levels, for instance. Few, however, are seeking to combine the two to get a 360-degree view of how our bodies are doing.

Into this gap steps Humanity Inc., which will seek to do exactly that. Founded by two seasoned entrepreneurs, Humanity will combine digital and biomedical biomarkers into a consumer app that will fully launch next year.

Today it announces it’s initial seed fundraise of $2.5m, in a round led by Boston fund One Way Ventures and the legendary and long-time HealthTech Angel investor Esther Dyson, among others.

Honey appears to be a preferable treatment for cough or cold symptoms rather than antibiotics and over-the-counter medicines, according to a new systematic review that’s looked at the results from 14 previous studies — but the conclusions may not be quite so clear-cut as they appear at first.

“Honey is a frequently used lay remedy that is well known to patients,” write the researchers from the University of Oxford in the UK. “It is also cheap, easy to access and has limited harms.”

One particular area of interest is the comparison of honey to antibiotics. With antibiotics often causing side effects and antibiotic resistance on the rise, there are multiple advantages to using honey as an alternative remedy, the authors of the review point out.

Summary: Researchers identified a group of closely related genes that capture molecular links between Alzheimer’s and LATE, a common brain disorder that mimics Alzheimer’s symptoms.

Alzheimer’s disease is one of the most common causes of dementia, and while most people might know someone who is affected by it, the genetic factors behind the disease are less known. A new study by investigators from Brigham and Women’s Hospital uncovered a group of closely related genes that may capture molecular links between Alzheimer’s disease and Limbic-predominant Age-related TDP-43 Encephalopathy, or LATE, a recently recognized common brain disorder that can mimic Alzheimer’s symptoms. LATE is often combined with Alzheimer’s disease to cause a more rapid cognitive decline. The study’s results are published in Neuron.

Astronomers have used NASA’s Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour. This is about 25,000 times faster than the speed of sound on Earth.

Kepler’s supernova remnant is the debris from a detonated star that is located about 20,000 light years away from Earth in our Milky Way galaxy. In 1604 early astronomers, including Johannes Kepler who became the object’s namesake, saw the supernova explosion that destroyed the star.

We now know that Kepler’s supernova remnant is the aftermath of a so-called Type Ia supernova, where a small dense star, known as a white dwarf, exceeds a critical mass limit after interacting with a companion star and undergoes a thermonuclear explosion that shatters the white dwarf and launches its remains outward.
