Nov. 29, 2023 Researchers have uncovered a mechanism that safeguards the biallelic expression of haploinsufficient genes, shedding light on the importance of having two copies of each chromosome. A study identified the epigenetic regulator MSL2 an 'anti-monoallelic' factor that maintains biallelic gene dosage. This discovery not only reveals a communication system between parental alleles but also points to ...

Nov. 28, 2023 Heart disease kills 18 million people each year, but the development of new therapies faces a bottleneck: no physiological model of the entire human heart exists -- so far. A new multi-chamber organoid that mirrors the heart's intricate structure enables scientists to advance screening platforms for drug development, toxicology studies, and ...

Nov. 29, 2023 Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- gamma-ray bursts, or GRBs. The new unified model confirms that some long-lasting GRBs are created in the aftermath of cosmic mergers that spawn an ...

Nov. 29, 2023 While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. The simplest amino acid, carbamic acid, could have formed alongside stars or planets within interstellar ices. The findings could be used to train deep space instruments like the James Webb Space Telescope to search for prebiotic molecules in distant, ...

Nov. 28, 2023 Engineers have come up with a new way to teach robots to know when they don't know. The technique involves quantifying the fuzziness of human language and using that measurement to tell robots when to ask for further directions. Telling a robot to pick up a bowl from a table with only one bowl is fairly clear. But telling a robot to pick up a bowl when there are five bowls on the table generates ...

Nov. 28, 2023 Asteroid Phaethon, which is five kilometers in diameter, has been puzzling researchers for a long time. A comet-like tail is visible for a few days when the asteroid passes closest to the Sun during its orbit. However, the tails of comets are usually formed by vaporizing ice and carbon dioxide, which cannot explain this tail. The tail should be visible at Jupiter's distance from the ...

Nov. 28, 2023 Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a ...

Nov. 27, 2023 The intensity and frequency of extreme rainfall increases exponentially with global warming, a new study finds. The analysis shows that state-of-the-art climate models significantly underestimate how much extreme rainfall increases under global warming -- meaning that extreme rainfall could increase quicker than climate models ...
