| Jellyfish's stinging cells hold clues to biodiversity Posted: 12 May 2022 11:43 AM PDT The cnidocytes -- or stinging cells -- that are characteristic of sea anemones, hydrae, corals and jellyfish, and make us careful of our feet while wading in the ocean, are also an excellent model for understanding the emergence of new cell types, according to new research. |
| Bacteria with recording function capture gut health status Posted: 12 May 2022 11:43 AM PDT Researchers have equipped gut bacteria with data logger functionality as a way of monitoring which genes are active in the bacteria. These microorganisms could one day offer a noninvasive means of diagnosing disease or assessing the impact of a diet on health. |
| What caused this megatooth shark's massive toothache? Posted: 12 May 2022 09:19 AM PDT Did the world's largest prehistoric shark need an orthodontist, or did it just have a bad lunch? |
| Unusually fast beaked whale has special deep-sea hunting strategy Posted: 12 May 2022 09:19 AM PDT Biologists have successfully used biologgers to reveal insights into the lifestyle and hunting behaviur of the little-known species Sowerby's beaked whale. The team's first results show that these dolphins have a surprisingly different, much faster lifestyle than related species. |
| A first: Scientists grow plants in soil from the Moon Posted: 12 May 2022 09:18 AM PDT Scientists have, for the first time, grown plants in soil from the Moon. They used soil collected during the Apollo 11, 12 and 17 missions. In their experiment, the researchers wanted to know if plants would grow in lunar soil and, if so, how the plants would respond to the unfamiliar environment, even down to the level of gene expression. |
| Explosion on a white dwarf observed Posted: 12 May 2022 06:26 AM PDT When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super hot explosion and produce a fireball of X-ray radiation. A research team has now been able to observe such an explosion of X-ray light for the very first time. |
| Algae-powered computing: Scientists create reliable and renewable biological photovoltaic cell Posted: 12 May 2022 06:21 AM PDT Researchers have used a widespread species of blue-green algae to power a microprocessor continuously for a year -- and counting -- using nothing but ambient light and water. Their system has potential as a reliable and renewable way to power small devices. |
