Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels that may have been crucial to the proliferation of life forms millions of years ago.</description> <pubDate>Fri, 03 May 2024 13:53:31 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/05/240503135331.htm</guid> </item> <item> <title>Ice shelves fracture under weight of meltwater lakes</title> <link>https://www.sciencedaily.com/releases/2024/05/240503135322.htm</link> <description>Heavy pooling meltwater can fracture ice, potentially leading to ice shelf collapse.</description> <pubDate>Fri, 03 May 2024 13:53:22 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/05/240503135322.htm</guid> </item> <item> <title>Stretchable e-skin could give robots human-level touch sensitivity</title> <link>https://www.sciencedaily.com/releases/2024/05/240503111943.htm</link> <description>A stretchy electronic skin could equip robots and other devices with the same softness and touch sensitivity as human skin, opening up new possibilities to perform tasks that require a great deal of precision and control of force.</description> <pubDate>Fri, 03 May 2024 11:19:43 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/05/240503111943.htm</guid> </item> <item> <title>'Gap' in carbon removal: Countries' plans to remove CO2 not enough</title> <link>https://www.sciencedaily.com/releases/2024/05/240503111933.htm</link> <description>New research suggests that countries' current plans to remove CO2 from the atmosphere will not be enough to comply with the 1.5 C warming limit set out under the Paris Agreement.</description> <pubDate>Fri, 03 May 2024 11:19:33 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/05/240503111933.htm</guid> </item> <item> <title>Scientists track 'doubling' in origin of cancer cells</title> <link>https://www.sciencedaily.com/releases/2024/05/240502141250.htm</link> <description>Working with human breast and lung cells, scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of cancer cells.</description> <pubDate>Thu, 02 May 2024 14:12:50 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/05/240502141250.htm</guid> </item> <item> <title>Sugar-based catalyst upcycles carbon dioxide</title> <link>https://www.sciencedaily.com/releases/2024/05/240502141205.htm</link> <description>New catalyst is made from an inexpensive, abundant metal and table sugar. Catalyst converts carbon dioxide (CO2) into carbon monoxide, a building block for producing a variety of useful chemicals including syngas. With recent advances in carbon capture technologies, post-combustion carbon capture is becoming a plausible option to help tackle the global climate change crisis. But how to handle the captured carbon remains an open-ended question. The new catalyst potentially could provide one solution for disposing the potent greenhouse gas by converting it into a more valuable product.</description> <pubDate>Thu, 02 May 2024 14:12:05 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/05/240502141205.htm</guid> </item> <item> <title>Random robots are more reliable</title> <link>https://www.sciencedaily.com/releases/2024/05/240502113808.htm</link> <description>New algorithm encourages robots to move more randomly to collect more diverse data for learning.

However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.</description> <pubDate>Wed, 01 May 2024 09:16:19 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/05/240501091619.htm</guid> </item> <item> <title>Climate change and mercury pollution stressed plants for millions of years</title> <link>https://www.sciencedaily.com/releases/2024/04/240430145626.htm</link> <description>The link between massive flood basalt volcanism and the end-Triassic (201 million years ago) mass-extinction is commonly accepted. However, exactly how volcanism led to the collapse of ecosystems and the extinction of entire families of organisms is difficult to establish. Extreme climate change from the release of carbon dioxide, degradation of the ozone layer due to the injection of damaging chemicals, and the emissions of toxic pollutants, are all seen as contributing factors. One toxic element stands out: mercury.</description> <pubDate>Tue, 30 Apr 2024 14:56:26 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240430145626.htm</guid> </item> <item> <title>Webb captures top of iconic horsehead nebula in unprecedented detail</title> <link>https://www.sciencedaily.com/releases/2024/04/240430145620.htm</link> <description>NASA's James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula.

However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.</description> <pubDate>Mon, 29 Apr 2024 11:59:00 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240429115900.htm</guid> </item> <item> <title>Cardio-fitness cuts death and disease by nearly 20%</title> <link>https://www.sciencedaily.com/releases/2024/04/240429103047.htm</link> <description>Groundbreaking new research finds that an increased cardio fitness level will reduce your risk of death from any cause by nearly 20%.</description> <pubDate>Mon, 29 Apr 2024 10:30:47 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240429103047.htm</guid> </item> <item> <title>Scientists develop strong yet reusable adhesive from smart materials</title> <link>https://www.sciencedaily.com/releases/2024/04/240429103034.htm</link> <description>Scientists have developed a smart, reusable adhesive more than ten times stronger than a gecko's feet adhesion, pointing the way for development of reusable superglue and grippers capable of holding heavy weights across rough and smooth surfaces.

This smart adhesive can support extremely heavy weights, opening new possibilities for robotic grippers that allow humans to scale walls effortlessly, or climbing robots that can cling onto ceilings for survey or repair applications.</description> <pubDate>Mon, 29 Apr 2024 10:30:34 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240429103034.htm</guid> </item> <item> <title>Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables</title> <link>https://www.sciencedaily.com/releases/2024/04/240429103026.htm</link> <description>Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables.

A neuroscientist who studies learning in humans and animals, and who has long worked with mice, wondered why rodents often performed poorly in tests when they knew how to perform well. With a simple experiment, and by acting as 'a little bit of a mouse psychologist,' he and his team figured it out.</description> <pubDate>Fri, 26 Apr 2024 16:52:08 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240426165208.htm</guid> </item> <item> <title>New circuit boards can be repeatedly recycled</title> <link>https://www.sciencedaily.com/releases/2024/04/240426165151.htm</link> <description>Researchers have developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer -- a cutting-edge class of polymer -- into a jelly-like substance without damage, allowing solid components to be plucked out for reuse or recycling. With these 'vPCBs' (vitrimer printed circuit boards), researchers recovered 98% of the vitrimer and 100% of the glass fiber.</description> <pubDate>Fri, 26 Apr 2024 16:51:51 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240426165151.htm</guid> </item> <item> <title>Ancient Maya blessed their ballcourts</title> <link>https://www.sciencedaily.com/releases/2024/04/240426165137.htm</link> <description>Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico.

However, the risk of arrhythmias following this procedure is reportedly high. In a recent study, researchers tested a novel approach that involves injecting 'cardiac spheroids,' cultured from human stem cells, directly into damaged ventricles. The highly positive outcomes observed in primate models highlight the potential of this strategy.</description> <pubDate>Fri, 26 Apr 2024 11:00:17 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240426110017.htm</guid> </item> <item> <title>Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes</title> <link>https://www.sciencedaily.com/releases/2024/04/240426110014.htm</link> <description>Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.</description> <pubDate>Fri, 26 Apr 2024 11:00:14 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240426110014.htm</guid> </item> <item> <title>Climate change could become the main driver of biodiversity decline by mid-century</title> <link>https://www.sciencedaily.com/releases/2024/04/240425161518.htm</link> <description>Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study.

A team of researchers has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of nerve cells in the brain, the mitochondria of the liver cells change and prepare the liver for the adaptation of the sugar metabolism. The findings could open up new avenues for the treatment of type 2 diabetes.</description> <pubDate>Thu, 25 Apr 2024 16:15:04 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240425161504.htm</guid> </item> <item> <title>With hybrid brains, these mice smell like a rat</title> <link>https://www.sciencedaily.com/releases/2024/04/240425131554.htm</link> <description>Mice lacking an olfactory system have had their sense of smell restored with neurons from rats, the first time scientists have successfully integrated the sensory apparatus of one species into another.</description> <pubDate>Thu, 25 Apr 2024 13:15:54 EDT</pubDate> <guid isPermaLink="true">https://www.sciencedaily.com/releases/2024/04/240425131554.htm</guid> </item> <item> <title>How do birds flock?
