Finding quvigints in a quantum treasure map

Physicists at the University of Queensland have created a new method for finding unknown quantum states, called self-guided tomography, which enables them to locate quvigints more quickly and accurately in high dimensions. This technique uses machine learning to pick directions, collect data, and process it to find the target state.

How a ladybug warps space-time

Researchers at the University of Vienna have successfully measured the smallest gravitational force yet by using a ladybug-sized mass. The team, led by Markus Aspelmeyer and Tobias Westphal, has picked up on an idea from Henry Cavendish's 18th-century experiment to measure gravitational forces with increasing accuracy.

Face masks are a ticking plastic bomb

Researchers warn of the environmental threat posed by disposable face masks made from microplastic fibers, which can fragment into nanoplastics and contaminate ecosystems. The production of disposable masks is estimated to be on a similar scale as plastic bottles, but with no official recycling guidelines.

Fishers at risk in 'perfect storm'

UK fishers face economic insecurity and climate-driven storms, making it harder to balance risks and rewards. The study suggests that factors like household income, fishing success, and crew support influence decision-making, with skippers taking greater risks when expecting good catches.

Demystifying the 'Parkinson Protein'

A team led by Professor Malte Drescher successfully observed the membrane binding of α-synuclein in living cells using a new measurement method. The study provides direct evidence that α-synuclein interacts with intracellular membranes, which may play a role in Parkinson's disease development.

Bitcoin price boom 'locking in' vast energy consumption

The surging Bitcoin price is driving increasing energy consumption, with estimates suggesting the entire network could consume up to 184 TWh per year. This 'lock-in' effect means that even if the price crashes, energy consumption remains high, threatening international safety and exacerbating climate change.

As cases spread across US last year, pattern emerged suggesting link between governors' party affiliation and COVID-19 case and death numbers

A study found that US states with Republican governors experienced higher COVID-19 cases and deaths after mid-summer, possibly due to differing policies. The analysis suggests that governor party affiliation may contribute to public health policy decisions, influencing the pandemic's impact.
