  • Biomedical engineering: A self-powered pacemaker in pigs

    Nature Communications, April 24, 2019

    A battery-free device that harvests energy from heart beats to power a cardiac pacemaker is reported in Nature Communications this week. The implantable device, demonstrated in adult pigs, was also capable of correcting sinus arrhythmia (an irregularity in the heart rhythm).

    Current pacemakers and other implantable medical devices are powered by batteries that are bulky, rigid, and shor...

  • Apollo-era tectonic activity on the Moon

    Nature Geoscience, May 14, 2019

    Some shallow moonquakes recorded during the Apollo programme were likely caused by tectonic activity, according to a paper published online this week in Nature Geoscience.

    The discovery of young faults less than 50 million years old on the Moon by the Lunar Reconnaissance Orbiter Camera in 2010 has been interpreted as evidence of lunar tectonic activity. However, it is unclear how recen...

  • Medical research: Repairing wounds with light-activated ‘bio-glue’

    Nature Communications, May 15, 2019

    A light-activated adhesive gel that can rapidly seal wounds to arteries and the heart is presented in an article published in Nature Communications. The ‘bio-glue’, demonstrated in a pig model, could have potential applications in surgery in the future. However, additional studies are needed to confirm the safety of the gel for its use in further trials, including those involving humans.

  • Global health: Rural lifestyles drive obesity

    Nature, May 9, 2019

    The global rise in body-mass index (BMI) seen over the last 30 years is largely due to increases in the BMI of rural populations, a Nature paper suggests. The study challenges the predominant paradigm, which links obesity with urban lifestyles, and could have profound implications for public health policies.

    While global obesity rates rise, more and more people are living in cities. Thi...

  • Planetary science: Mantle material on the far side of the Moon

    Nature, May 16, 2019

    Measurements from China’s Chang’E-4 mission to the far side of the Moon suggest the presence of material from the lunar mantle at the landing site. The findings, published in Nature this week, could provide insights into the composition of the Moon’s mantle.

    The detailed structure of the Moon’s mantle has eluded investigators for years and, in order to solve this problem, attent...

  • Tiny tyrannosauroid fills a big gap

    Nature Ecology & Evolution, May 7, 2019

    The fossils of a newly discovered species of small tyrannosauroid dinosaur that were found in New Mexico, United States, are described in a paper published online this week in Nature Ecology & Evolution. These specimens, two associated juvenile skeletons dated to around 92 million years ago, provide insight into the little-understood origins of Tyrannosaurus rex and its closely related cousins....

  • Medical research: Regenerating injured lungs in pigs

    Nature Communications, May 8, 2019

    The regeneration of damaged pig lungs using an external organ support system is reported in Nature Communications this week. The preliminary findings suggest that it may be possible to recover damaged lungs for use in organ transplantation.

    Gastric aspiration - the entry of gastric material into the respiratory tract - is a common injury that renders lungs unsuitable for transplantation...

  • Neuroscience: Gut-synthesized amino acid regulates sleep in Drosophila

    Nature Communications, May 8, 2019

    An amino acid produced in the intestine has an important role in regulating sleep in Drosophila (fruit flies), reports a paper published online this week in Nature Communications. The amino acid, called D-serine, is conserved between Drosophila and mammals and the findings could lead to insights into the regulation of sleep.

    D-serine was thought to exist only in bacteria until relativel...

  • Fossils: More evidence for bat-like flight in tiny dinosaurs

    Nature, May 9, 2019

    The fossil of a newly discovered species of scansoriopterygid dinosaur with bat-like wings, found in Liaoning Province, China, is described in a paper published this week in Nature. This specimen, dated to around 163 million years ago, provides further evidence that suggests that dinosaurs closely related to birds experimented with different wing structures near the origins of flight.

  • Ecology: River connections in decline

    Nature, May 9, 2019

    Only one third of the world’s longest rivers (over 1,000 kilometres in length) remain free-flowing, and these are restricted to remote regions in the Arctic and the Amazon and Congo basins, according to a paper published in Nature. The findings demonstrate how human activity disrupts river connectivity, which threatens the ecosystems and services provided by free-flowing rivers.
