Invisible “dark matter” stars may explain puzzling gravitational waves

Last year scientists detected gravitational waves from what appeared to be the most massive black hole collision ever recorded. But now an international team of astrophysicists has proposed an exotic alternative – the data may actually favor a collisio… Continue reading Invisible “dark matter” stars may explain puzzling gravitational waves→

New concrete recipe improves its carbon capture efficiency

Concrete is one of the world’s most commonly used materials, and unfortunately its production is a major source of carbon dioxide in the atmosphere. Now, engineers at Purdue University have developed a new cement recipe that can absorb CO2 twice as fas… Continue reading New concrete recipe improves its carbon capture efficiency→

Astronomers identify most distant known object in the solar system

For a long time, Pluto was the farthest object we knew about in the solar system, but it’s a cosmic stone’s-throw away compared to more recent discoveries. Now astronomers have confirmed what is currently the most distant world of all – the appropriate… Continue reading Astronomers identify most distant known object in the solar system→

Fully foldable solar cell bends in half without breaking

Picture solar panels, and you’re most likely picturing a solid square slab. But the tech is becoming more flexible, and now engineers at Pusan National University in Korea have developed prototype solar cells that are fully foldable.Continue ReadingCat… Continue reading Fully foldable solar cell bends in half without breaking→

Allergy seasons getting longer and more severe thanks to climate change

For many people, the beauty of spring is countered by the sneezing, runny nose and itchy eyes of allergies that come with the warmer weather. For those people, science has some bad news – climate change seems to be making pollen season longer and more … Continue reading Allergy seasons getting longer and more severe thanks to climate change→

Smoking gun of rare “zombie star” supernova discovered in Milky Way

Astronomers have identified the remains of a rare type of supernova in our home galaxy for the first time. These events, known as Type Iax supernovae, occur when white dwarfs explode and may leave behind a “zombie star.”Continue ReadingCategory: Space,… Continue reading Smoking gun of rare “zombie star” supernova discovered in Milky Way→

Immune cell “switch” helps send inflammatory bowel disease into remission

Inflammatory bowel diseases (IBD), including ulcerative colitis and Crohn’s disease, are unpleasant, chronic conditions with few effective treatment options. Now, researchers at KU Leuven and Seoul National University may have found a way to potentiall… Continue reading Immune cell “switch” helps send inflammatory bowel disease into remission→

Electricity-free radiative system cools buildings and heats water

Air conditioners and other cooling systems are among our biggest consumers of electricity, so finding ways to passively cool buildings will be important in our increasingly warmer future. Now, researchers at the University at Buffalo have developed a p… Continue reading Electricity-free radiative system cools buildings and heats water→

Drugs that trip cellular alarm could help clear out hibernating HIV

HIV can currently be managed with a lifelong daily drug regimen, but unfortunately the infection can’t be eliminated entirely. Now, researchers have found a potential way to trip a cellular “alarm” to alert the immune system to clear out infected cells… Continue reading Drugs that trip cellular alarm could help clear out hibernating HIV→
