Published Scientists unveil fire-safe fuel
(via sciencedaily.com)
Original source 
Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a 'safe' liquid fuel.
Published A turtle time capsule: DNA found in ancient shell
(via sciencedaily.com)
Original source 
Paleontologists discover possible DNA remains in fossil turtle that lived 6 million years ago in Panama, where continents collide.
Published Unlocking the potential of silicon anode materials for commercialized batteries
(via sciencedaily.com)
Original source 
A research team presented an analysis protocol to evaluate silicon cathode materials applicable to commercialized batteries.
Published Novel battery technology with negligible voltage decay
(via sciencedaily.com)
Original source 
A pivotal breakthrough in battery technology that has profound implications for our energy future has been achieved.
Published Capturing CO2 with electricity: A microbial enzyme inspires electrochemistry
(via sciencedaily.com)
Original source 
Humanity continuously emits greenhouse gases and thereby worsens global warming. Increasing research efforts go into developing strategies to convert these gases, such as carbon dioxide (CO2), into valuable products. CO2 accumulates dramatically over the years and is chemically very stable, thus challenging to transform. Yet, for billions of years, some microbes have actively captured CO2 using highly efficient enzymes. Scientists have now isolated one of these enzymes. When the enzyme was electronically branched on an electrode, they observed the conversion of CO2 to formate with perfect efficiency. This phenomenon will inspire new CO2-fixation systems because of its remarkable directionality and rates.
Published What makes a carrot orange?
(via sciencedaily.com)
Original source 
Three recessive genes are required to give carrots their orange color -- and the beneficial precursor of vitamin A.
Published A new twist on rechargeable battery performance
(via sciencedaily.com)
Original source 
Rechargeable battery performance could be improved by a new understanding of how they work at the molecular level. Researchers upend what's known about how rechargeable batteries function.
Published Accelerating sustainable semiconductors with 'multielement ink'
(via sciencedaily.com)
Original source 
Scientists have demonstrated 'multielement ink' -- the first 'high-entropy' semiconductor that can be processed at low-temperature or room temperature. The new material could enable cost-effective and energy-efficient semiconductor manufacturing.
Published How a suction cup delivers medications to the bloodstream
(via sciencedaily.com)
Original source 
A mini-suction cup allows for the painless administration of medications that previously could only be injected. It stretches the mucosal lining of the cheek and, in combination with a penetration-promoting agent, makes this barrier more permeable to medications. The researchers now want to bring their new delivery system to market.
Published Wearable patch wirelessly monitors estrogen in sweat
(via sciencedaily.com)
Original source 
A new sensor may make it easier for women to monitor their estradiol, which plays a role in health and fertility.
Published Vision in the brain: Hardwired for action
(via sciencedaily.com)
Original source 
Brain circuits for vision develop without any kind of input from the retina in zebrafish.
Published Why are killer whales harassing and killing porpoises without eating them?
(via sciencedaily.com)
Original source 
For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Published New study removes human bias from debate over dinosaurs' demise
(via sciencedaily.com)
Original source 
Researchers tried a new approach to resolve the scientific debate over whether it was a giant asteroid or volcanoes that wiped out the dinosaurs -- they removed scientists from the debate and let the computers decide. The researchers created a model powered by 130 interconnected processors that, without human input, reverse-engineered the Cretaceous-Paleogene mass extinction until they reached a scenario that matched the fossil record. The model determined that while a meteorite contributed to the cataclysm, the outpouring of climate-altering gases from the nearly 1-million-year eruptions of volcanoes in western India's Deccan Traps would have been sufficient to trigger the extinction and clear the way for the ascendance of mammals.
Published Ethical guidelines needed before human research in commercial spaceflight is ready for liftoff
(via sciencedaily.com)
Original source 
Before human research is conducted during commercial spaceflights, it should be 'ethically cleared to launch,' according to a global team of scientists, health policy experts and commercial spaceflight professionals.
Published Whales Around the World Play With Kelp Clumps
(via sciencedaily.com)
Original source 
A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.
Published Sperm swimming is caused by the same patterns that are believed to dictate zebra stripes
(via sciencedaily.com)
Original source 
Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. This new study shows that the mathematical basis of these patterns also governs how sperm tail moves.
Published New information on the most important early stage of embryonic development
(via sciencedaily.com)
Original source 
A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development.
Published Plastic cloud: New study analyzes airborne microplastics in clouds
(via sciencedaily.com)
Original source 
Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a new study, researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. They also shed light on how these airborne particles influence cloud formation and their negative impact on the climate.
Published Atlantic walrus more vulnerable than ever to Arctic warming
(via sciencedaily.com)
Original source 
Past cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues affecting them severely, according to a new study.
Published Tiny CRISPR tool could help shred viruses
(via sciencedaily.com)
Original source 
Scientists mapped out the three-dimensional structure of one of the smallest known CRISPR-Cas13 systems then used that knowledge to modify its structure and improve its accuracy.
