Protein test could lead to earlier and better diagnosis of Parkinson’s
Scientists at the Oxford Parkinson's Disease Centre (OPDC) have been able to use a highly-sensitive method called -synuclein real-time quaking-induced conversion (?Syn-RT-QuIC) to observe the clumping of alpha-synuclein in the cerebrospinal fluid (CSF) taken from people with Parkinson's. The findings offer hope that a pioneering new clinical test could be developed to diagnose Parkinson's correctly in its early stages.

New health economic framework to help assess what might be required to eliminate African sleeping sickness by 2030
· To successfully eliminate a disease, global-health decision makers have to establish if current tools are sufficient to achieve elimination, however they must also consider whether investment in elimination is a good use of limited resources · Mathematical and health economic modelling can be used to predict which intervention strategies have a high probability of successfully eliminating a disease as well as how much this would be expected to cost.

The genetic changes caused by fishing may be linked to fish population size
The genetic changes caused by fishing may be linked to fish population size
Commercial fishing, particularly in reduced fish populations, may be responsible for genetic changes and affect overall population resilience if not carefully managed. A new study, led by the University of Glasgow and published in PNAS, examined how commercial fishing practices - such as trawling - impacted the genetic evolution of fish populations, both directly and through reduced fish population density, mimicking declines in stocks due to over-fishing.

Community of ethical hackers needed to prevent AI's looming 'crisis of trust'
Community of ethical hackers needed to prevent AI’s looming ’crisis of trust’
A global hacker "red team" and rewards for hunting algorithmic biases are just some of the recommendations from experts who argue that AI faces a "tech-lash" unless firm measures are taken to increase public trust. We need policy and public support to create an ecosystem of trust for AI Shahar Avin The Artificial Intelligence industry should create a global community of hackers and "threat modellers" dedicated to stress-testing the harm potential of new AI products in order to earn the trust of governments and the public before it's too late.

Precision sieving of gases through atomic pores in graphene
Precision sieving of gases through atomic pores in graphene
By crafting atomic-scale holes in atomically thin membranes, it should be possible to create molecular sieves for precise and efficient gas separation, including extraction of carbon dioxide from air, University of Manchester researchers have found. If a pore size in a membrane is comparable to the size of atoms and molecules, they can either pass through the membrane or be rejected, allowing separation of gases according to their molecular diameters.
