Astrophysicist Explains Science Behind Once-in-a-Lifetime Nova Outburst that will Light up the Sky this Year

Posted by in categories: physics, science, space

The total solar eclipse isn’t the only reason to keep your eyes to the sky this year. For the first time in 80 years, a star system 3,000 light years away will be visible to the naked eye thanks to a once-in-a-lifetime nova outburst.

NASA announced that the nova, which will create a “new” star in the night sky, will light up the night sky some time between now and September and be as bright as the North Star. One of only five recurring novae in our galaxy, it will be visible for a week before it fades back down.

Jonathan Blazek, an assistant professor of physics at Northeastern University, says this is an exciting moment for amateur astronomers and astrophysicists alike. It’s not technically a new star, just a star that is now bright enough for people to see more clearly, Blazek says, but it provides an opportunity to see and understand the cosmos in a new way.

Sustainable Plastics from Agricultural Waste

Posted by in categories: food, sustainability

Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.

In our rapidly industrialized world, the quest for sustainable materials has never been more urgent. Plastics, ubiquitous in daily life, pose significant environmental challenges, primarily due to their fossil fuel origins and problematic disposal.

Now, a study led by Jeremy Luterbacher’s team at EPFL unveils a pioneering approach to producing high-performance plastics from renewable resources.

Severe Lung Infection during COVID-19 can cause Damage to the Heart

Posted by in category: biotech/medical

SARS-CoV-2, the virus that causes COVID-19, can damage the heart even without directly infecting the heart tissue, a study has found. The research, published in the journal Circulation, specifically looked at damage to the hearts of people with SARS-CoV-2-associated acute respiratory distress syndrome (ARDS), a serious lung condition that can be fatal. But researchers said the findings could have relevance to organs beyond the heart and also to viruses other than SARS-CoV-2.

Scientists have long known that COVID-19 increases the risk of heart attack, stroke, and Long COVID, and prior imaging research has shown that over 50% of people who get COVID-19 experience some inflammation or damage to the heart. What scientists did not know was whether the damage occurs because the virus infects the heart tissue itself, or because of systemic inflammation triggered by the body’s well-known immune response to the virus.

“This was a critical question and finding the answer opens up a whole new understanding of the link between this serious lung injury and the kind of inflammation that can lead to cardiovascular complications,” said Michelle Olive, Ph.D., associate director of the Basic and Early Translational Research Program at the National Heart, Lung, and Blood Institute (NHLBI), part of NIH. “The research also suggests that suppressing the inflammation through treatments might help minimize these complications.”

Apple researchers develop AI that can ‘see’ and understand screen context

Posted by in category: robotics/AI

Apple researchers have developed a new artificial intelligence system that can understand ambiguous references to on-screen entities as well as conversational and background context, enabling more natural interactions with voice assistants, according to a paper published on Friday.

The system, called ReALM (Reference Resolution As Language Modeling), leverages large language models to convert the complex task of reference resolution — including understanding references to visual elements on a screen — into a pure language modeling problem. This allows ReALM to achieve substantial performance gains compared to existing methods.

Scientists Propose New Method To Detect Consciousness in Infants

Posted by in category: neuroscience

Academics are proposing a new and improved way to help researchers discover when consciousness emerges in human infancy.

When over the course of development do humans become conscious? When the seventeenth-century French philosopher René Descartes was asked about infant consciousness by his critics, he eventually suggested that infants might have thoughts, albeit ones that are simpler than those of adults. Hundreds of years later, the issue of when human beings become conscious is a question which remains a challenge for psychologists and philosophers alike.

But now, in response to a recent article in Trends in Cognitive Sciences, two academics from the University of Birmingham have suggested an improved way to help scientists and researchers identify when babies become conscious.
