'Slushy' magma ocean led to formation of the Moon’s crust

Posted: 13 Jan 2022 06:21 AM PST

Scientists have shown how the freezing of a 'slushy' ocean of magma may be responsible for the composition of the Moon's crust.

Fastest DNA sequencing technique helps undiagnosed patients find answers in mere hours

A research effort set the first Guinness World Record for the fastest DNA sequencing technique, which was used to sequence a human genome in just 5 hours and 2 minutes.

Tiger shark migrations altered by climate change

Posted: 13 Jan 2022 06:21 AM PST

A new study has revealed that the locations and timing of tiger shark movement in the western North Atlantic Ocean have changed from rising ocean temperatures. These climate-driven changes have subsequently shifted tiger shark movements outside of protected areas, rendering the sharks more vulnerable to commercial fishing.

Machine learning for morphable materials

Posted: 12 Jan 2022 12:49 PM PST

Flat materials that can morph into three-dimensional shapes have potential applications in architecture, medicine, robotics, space travel, and much more. But programming these shape changes requires complex and time-consuming computations. Now, researchers have developed a platform that uses machine learning to program the transformation of 2D stretchable surfaces into specific 3D shapes.

The ‘Platypus’ of the crab world was an active predator that lurked the Cretaceous seas

Researchers describe the unusually large optical features of Callichimaera perplexa, a 95-million-year-old crab fossil discovered in Colombia. The findings suggest Callichimaera perplexa was a highly visual, swimming predator.

Regrowing knee cartilage with an electric kick

Bioengineers successfully regrew cartilage in a rabbit's knee, a promising hop toward healing joints in humans.

Microplastic pollution linger in rivers for years before entering oceans

Posted: 12 Jan 2022 11:50 AM PST

Because rivers are in near-constant motion, researchers previously assumed lightweight microplastics quickly flowed through rivers, rarely interacting with riverbed sediments. With new simulations, researchers now have discovered hyporheic exchange -- a process in which surface water mixes with water in the riverbed -- can trap lightweight microplastics that otherwise might be expected to float.

Predator species help to buffer climate change impacts on biodiversity

Posted: 12 Jan 2022 09:15 AM PST

Predator species may buffer the negative impacts of climate change by mitigating against the loss of biodiversity, according to new research. The team of scientists behind the discovery say their findings underline the importance of conserving biodiversity, and top predators in particular, and highlight the potential for species extinctions to worsen the effects of climate change on ecosystems.

Epigenetic mechanisms for parent-specific genetic activation decoded

Posted: 12 Jan 2022 09:15 AM PST

Hereditary diseases as well as cancers and cardiovascular diseases may be associated with a phenomenon known as genomic imprinting, in which only the maternally or paternally inherited gene is active. An international research team has now investigated the mechanisms responsible for the deactivation of the genes.

New discovery on regulation of organelle contacts

Posted: 12 Jan 2022 07:57 AM PST

A pioneering study has revealed how cellular compartments (organelles) are able to control how much they interact and cooperate.

Study may help clinicians use sleep brain wave patterns to diagnose dementia and other forms of cognitive impairment

Posted: 12 Jan 2022 07:56 AM PST

Researchers have characterized how spindle detection parameter settings influence the association between spindles and cognition, and they identified parameters that best correlate with cognitive performance.
