The researchers use the 'remarkable evidence' to tell a compelling story from 45,000-50,000 years ago with new detail: how the first humans migrated across Europe and Asia.]]> Fri, 22 Sep 2023 20:12:47 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWhLGG3ThvybjeT5HJgy6HUf https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiIHiByVpRxUJVjH6qdYdAk Using ancestry decomposition techniques an international research team has revealed a deeply divergent ancestry among admixed populations from the Angolan Namib desert. This unique genetic heritage brings the researchers closer to understanding the distribution of genetic variation in the broader region of southern Africa before the spread of food production.]]> Fri, 22 Sep 2023 20:12:44 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiIHiByVpRxUJVjH6qdYdAk https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj-9jA_Wd3E-cb1naedg1wr Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.]]> Fri, 22 Sep 2023 17:08:45 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj-9jA_Wd3E-cb1naedg1wr https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj-9jA_Wd3E-aCY3L745TL_ With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time we now see signs that this relation between the amount of stars and elements does not hold for the earliest galaxies. The reason is likely that these galaxies simply are in the process of being created, and have not yet had the time to create the heavy elements.]]> Fri, 22 Sep 2023 17:08:09 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj-9jA_Wd3E-aCY3L745TL_ https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWgv31XH9FxxOZs0ohxaO6Yr One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding. By getting the birds to fly a little further north, researchers have observed that these birds can give their chicks a better start in life.]]> Fri, 22 Sep 2023 17:08:06 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWgv31XH9FxxOZs0ohxaO6Yr https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWgv31XH9FxxOXn9ye8UNv30 Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research.]]> Fri, 22 Sep 2023 17:07:58 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWgv31XH9FxxOXn9ye8UNv30 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj6Xt_tJEgIX8b1naedg1wr Astronomers using data from NASA's James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Europa.]]> Fri, 22 Sep 2023 17:07:33 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj6Xt_tJEgIX8b1naedg1wr https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj6Xt_tJEgIX-T5HJgy6HUf When you see a familiar face upright, you'll recognize it right away. But if you saw that same face upside down, it's much harder to place. Now researchers who've studied Claudio, a 42-year-old man whose head is rotated back almost 180 degrees such that it sits between his shoulder blades, suggest that the reason people are so good at processing upright faces has arisen through a combination of evolution and experience.]]> Fri, 22 Sep 2023 17:07:16 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj6Xt_tJEgIX-T5HJgy6HUf https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWhBzLR1uveMbuT5HJgy6HUf Plant scientists have engineered a light-controlled gene expression system (optogenetics system) from a prokaryotic system into a eukaryotic system that is tailored for plants.]]> Thu, 21 Sep 2023 21:45:58 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWhBzLR1uveMbuT5HJgy6HUf https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViZs0ohxaO6Yr Reducing CO2 levels in the atmosphere will take more than cutting emissions -- we will also need to capture and store the excessive volumes of already-emitted carbon. A team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.]]> Thu, 21 Sep 2023 21:45:43 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViZs0ohxaO6Yr https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViV1cWWor9YPv Balanophora shed one third of its genes as it evolved into a streamlined parasitic plant -- an extreme degree of genome shrinkage even among parasites. Along the way this subtropical plant developed the ability to induce the host plant to grow into the parasite's own flesh -- forming chimeric organs that mix host and parasite tissues.]]> Thu, 21 Sep 2023 21:45:26 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViV1cWWor9YPv https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViXn9ye8UNv30 Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution.]]> Thu, 21 Sep 2023 21:45:21 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViXn9ye8UNv30 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pVieT5HJgy6HUf Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.]]> Thu, 21 Sep 2023 21:44:58 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pVieT5HJgy6HUf https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViSejEQ2Mq9rY Geothermal heat offers a promising source of renewable energy with almost zero emissions, but it remains a relatively expensive option to generate electricity. A new technique may help prevent 'short-circuits' that can cause geothermal power plants to halt production, potentially improving the efficiency of geothermal power, the researchers said.]]> Thu, 21 Sep 2023 21:44:36 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjXyPn6B7pViSejEQ2Mq9rY https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWif_CfhoYhIUJs0ohxaO6Yr In a new study in mice, researchers have uncovered a crucial component for restoring functional activity after spinal cord injury.
