Understanding how mutations affect diseases

Understanding how mutations affect diseases
2024-10-28
Many statistical models and algorithms used by scientists can be imagined as a “black box.” These models are powerful tools that give accurate predictions, but their internal workings are not easily interpretable or understood. In an era dominated by deep learning, where an ever-increasing amount of data can be processed, Natália Ružičková, a physicist and PhD student at the Institute of Science and Technology Austria (ISTA), chose to take a step back. At least in the context of genomic ...

Quality control in artificial photosynthesis: validating natural antenna mimicry

Quality control in artificial photosynthesis: validating natural antenna mimicry
2024-10-28
Humans can do plenty, but plants have an ability we don’t: they make energy straight from sunlight, a superpower called photosynthesis. Yet new research shows that scientists are closing that gap. Osaka Metropolitan University researchers have revealed the 3D structure of an artificial photosynthetic antenna protein complex, known as light-harvesting complex II (LHCII), and demonstrated that the artificial LHCII closely mirrors its natural counterpart. This discovery marks a significant step forward in understanding how plants harvest and manage solar energy, paving the way for future innovations in artificial ...

When science speaks in extremes

When science speaks in extremes
2024-10-28
“Vaccines are 100% safe, and anyone who doubts this is ignorant”: Have you ever come across messages like this during the pandemic crisis a few years ago? If you often feel that certain public debates—such as those on vaccines or the climate crisis—boil down to a black-and-white clash between two sides demanding, with harsh tones, unquestioning allegiance to their view, you're not entirely wrong. We are rightly accustomed to being warned about pseudoscientific misinformation and fake news, and much research has been devoted ...

Will the ocean suffer an epidemic?

Will the ocean suffer an epidemic?
2024-10-28
Written by a team of European experts from the marine sciences, Navigating the Future VI discusses how the biodiversity crisis is being played out in the Ocean. It notes that Ocean species large and small are far less well described than their terrestrial counterparts, making it harder to measure declines and their impacts. This publication provides governments, policymakers and funders with robust, independent scientific advice on future seas and Ocean research. With the COP16 on biodiversity already in full swing in Cali, Colombia, it is timely to reflect further on the need to better understand our Ocean biodiversity. “Climate change ...

Magicians don’t mind sharing the secrets behind tricks – if they are their own

Magicians don’t mind sharing the secrets behind tricks – if they are their own
2024-10-27
Magic is one of the oldest forms of entertainment, and much of its enchantment is said to rely on the audience not knowing how the tricks are done. However, while magicians swear to keep their secrets forever when they embark on their profession they are happy to share the tricks of their trade in certain circumstances, a new study shows. Illusionists who took part in major new research thought it was OK to expose their own techniques, but not those invented by others, and also believe it is acceptable to reveal the secrets behind tricks invented by someone who has since died. They didn’t think it was right to share the workings of a magic trick just to gain public ...

No incentive for older birds to make new friends

No incentive for older birds to make new friends
2024-10-27
Like people, birds have fewer friends as they age, but the reasons why are unclear. New research suggests they may just have no drive to. In humans, it’s often been assumed that older people have fewer friends because they’re pickier about who they spend their time with. There’s also the issue that there are fewer people of their own age around. But it’s hard to pick apart the various potential causes for humans, so researchers have turned to animals. The team behind the new research, led by Imperial College London, studied an isolated population of sparrows on the island of Lundy, in the Bristol Channel. By mapping the ...

Liver characterization of a cohort of alpha-1 antitrypsin deficiency patients with and without lung disease

2024-10-26
Background and Aims Alpha-1 antitrypsin deficiency (AATD) is a genetic disorder characterized by the misfolding and accumulation of the mutant variant of alpha-1 antitrypsin (AAT) within hepatocytes, which limits its access to the circulation and exposes the lungs to protease-mediated tissue damage. This results in progressive liver disease secondary to AAT polymerization and accumulation, and chronic obstructive pulmonary disease (COPD) due to deficient levels of AAT within the lungs. Our goal was to characterize the unique effects of COPD secondary to AATD on liver disease and gene expression. Methods A ...
