Even during one of Earth’s largest mass extinction events, where heat waves kill of a majority of Earth’s species, at least one oasis of survival existed.The findings suggest that there may have been pockets of protection throughout Earth — challenging the notion that the heat affected life on the planet uniformly, according to a paper in Science Advances.Living Through "The Great Dying"About 250 million years ago, a series of massive volcanic eruptions warmed Earth. This period, sometimes ...read more
Uncertainty is just what it sounds like: not knowing. It’s that state of limbo when you’re waiting to find out if you got the job, if the biopsy is negative, if you’re pregnant or not. It’s not knowing who’s the best candidate or which brand of car is likely to last the longest. It’s also not knowing the answers to those existential questions: Why am I here? How is everything going to turn out? Most research on uncertainty has focused on its negative aspects, primarily anxiety. Ho ...read more
In an unprecedented procedure, CRISPR gene editing has been used to treat cancer. A research team from Tel Aviv University, led by Razan Masarwy, successfully used CRISPR to cut a gene from head and neck cancers. Following the procedure, 50 percent of the targeted tumors disappeared 84 days after treatment. Their findings were published in Advanced Science.Collapsing the Cancer PyramidDan Peer, Director of the Laboratory of Precision Nanomedicine, and his colleagues are pioneers in mRNA-based ...read more
Many of us have taken first-aid classes in school — a vital skill in any emergency where unconscious individuals require immediate assistance. This training includes assessing the situation, checking vital signs, calling for help, and even performing CPR (cardiopulmonary resuscitation) if necessary.While technical aspects of first aid need to be taught and practiced, the instinct to help others in distress is deeply ingrained in human nature. And we're not alone: Various animal species have al ...read more
In the ongoing quest to understand dark matter, researchers are now wondering if a strange phenomenon occurring at the heart of the Milky Way galaxy could be from a different form of dark matter. Dark matter is a mysterious substance that could make up 85 percent of the Universe’s mass, and researchers have been working endlessly to find and understand it. Now, a new study published in Physical Review Letters is looking at a new candidate for dark matter that could be causing unexplained chem ...read more
