Phys.org / The sun is tearing an asteroid to pieces, and Earth is now flying through the fallout
Across Earth, every night, thousands of automated stargazers are waiting to take pictures of shooting stars. I am one of the scientists who study these meteors.
Medical Xpress / Blood test can predict Alzheimer's disease progression years before symptoms or brain scan changes
A study by investigators at Mass General Brigham has found that a blood test of plasma phosphorylated tau 217 (pTau217), an Alzheimer's disease biomarker, can predict the progression of amyloid PET scan changes and cognitive ...
Phys.org / Gene discovery opens new path for disease-resistant rice breeding
Bacterial blight (BB) is a serious plant disease that mainly affects rice plants, especially in warm, humid regions. Due to the severity of BB, discovering and applying BB-resistance genes is strategically important for ensuring ...
Medical Xpress / Therapy program for kids with lupus can change lives in 6 sessions
Often diagnosed in the teenage years, childhood-onset lupus is a serious, potentially fatal autoimmune disease that causes the body to attack itself. For as many as 10,000 U.S. youths, it can bring extreme fatigue, mood changes, ...
Phys.org / Birds that put more energy into parenthood age faster and die younger, research shows
In a new study, appearing in Proceedings of the Royal Society B: Biological Sciences, scientists selectively bred Japanese quails into two groups: laying either relatively large or small eggs. As the quails don't do much ...
Phys.org / Ancient Korean DNA reveals marriages between closely related individuals
DNA studies of 1,500-year-old skeletons have revealed that ancient Koreans lived in tightly knit family networks where marrying close relatives was common in some cases, from powerful elites to individuals chosen for human ...
Phys.org / 4,000-year-old clay tablets inscribed with magical spells… and beer tabs
For over 100 years, the National Museum has housed a large collection of inscribed tablets from the earliest civilizations of the Middle East—many over 4,000 years old and written in languages that are now extinct. The tablets ...
Phys.org / Cancer's hidden switch may sit in the cell membrane, forcing growth receptors into permanent overdrive
Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do more than simply provide ...
Phys.org / Extensive faults beneath Nevada nuclear lab raise unanswered earthquake risks
The underground laboratory in Nevada where the U.S. conducts nuclear subcritical experiments is riddled with faults. Researchers have not confirmed whether any of these faults are active and could rupture during an earthquake, ...
Phys.org / Scientists unlock shape-shifting living tissue, programming cells to fold flat sheets into precise 3D forms
Biological tissues have a remarkable ability to organize and change shape, driven by forces generated by their own cells. One of the major challenges in bioengineering is harnessing this natural behavior to design synthetic ...
Phys.org / ALMA confirms rare quasar pair at redshift 5.7 in merging galaxies
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered a close pair of quasars, which is a result of a distant massive galaxy merger. The detection of the quasar pair was detailed in a ...
Phys.org / Solar flares' domino effect isn't limited to the sun, 16,000-star sweep reveals
Our sun is a roiling mass of energy, with solar flares exploding on its surface, sending gas, plasma, and light that blasts across the solar system. When radiation from extra-powerful flares breaks through Earth's outer protective ...
