15hThis is a re-post from Yale Climate Connections by Dennis Laich, Larry Wilkerson, and Erik Edstrom The US military is about to find itself committed to yet another unwinnable mission costing trillions of dollars. No, we are not referring to the possibility of American escalation in Russia's brutal war against Ukraine: We are referring to the grim prospect of the American military's having to atte

Investigating the upper bound of high-frequency electromagnetic waves on unshielded twisted copper pairs
20hNature Communications, Published online: 26 April 2022; doi:10.1038/s41467-022-29631-8 This paper establishes a physical limit on the ability of the ubiquitous twisted pairs to support high speed internet. This limit due to radiation from the wire is theoretically explained as well as numerically simulated and experimentally measured.

Gastrointestinal issues linked with anxiety, social withdrawal for kids with autism
22hA new study found a 'bi-directional' relationship between gastrointestinal issues and internalized symptoms in children and adolescents with autism — meaning the symptoms seem to be impacting each other simultaneously. The findings could influence future precision medicine research aimed at developing personalized treatments to ease pain for individuals with autism experiencing gastrointestinal i
COVID-19 lockdown measures affect air pollution from cities differently
22hSeizing on a natural experiment created by restricted travel, researchers combine a network model with air pollution data before and during outbreaks.
Researchers develop a paper-thin loudspeaker
22hResearchers created an ultrathin loudspeaker that can turn any rigid surface into a high-quality, active audio source. The fabrication process can enable the thin-film devices to be produced at scale.

22hAlzheimer Women Men
A study is the first to examine if sex significantly affects cognitive outcomes in people who follow individually-tailored, multi-domain clinical interventions. The study also determined whether change in risk of developing cardiovascular disease (CVD) and Alzheimer's disease (AD), along with blood markers of AD risk, also were affected by sex. Results showed that while care in an Alzheimer's Prev
Death in darkness: A new type of cell death discovered in fly guts
22hA research group has discovered a completely unknown type of cell death that takes place in the guts of the common fruit fly. The new process, coined 'erebosis' by the researchers is thought to play a role in gut metabolism. The findings necessitate a revision of the conventional concept of cell death, and at the same time, overturn the previously established theory of tissue homeostasis in the gu
Poor diet associated with increased diabetes risk across all gradients of genetic risk
22hGenetic risk factors and diet quality are independently associated with type 2 diabetes; a healthy diet is linked to lower diabetes risk across all levels of genetic risk. That's the conclusion of a study of more than 35,000 U.S. adults.
Living near fast food restaurants in South Asia may increase risk of Type 2 diabetes

Parental type 1 diabetes can affect children's cognitive development
22hCognitive development in children could be affected regardless of which biological parent has type 1 diabetes, according to a new study. The research shows for the first time that having a parent with a chronic disease like type 1 diabetes may be associated with lower school performance rather than maternal high blood sugar during fetal development.
'Shielding' strategies instead of lockdowns would have led to tens of thousands more deaths, new modelling shows
22hShielding vulnerable people while allowing Covid-19 to run through the rest of the population had been proposed as an alternative strategy to lockdowns. Modelling by University of Bath scientists shows it would ultimately have failed as infections 'leak through' to the most vulnerable. Even in the most optimistic shielding scenario, critical care capacity in hospitals would have been massively exc
Lipidomics provides new biomarkers for cardiovascular disease and Type 2 diabetes
22hUsing lipidomics, a modern analytical method, researchers identified those lipids that are statistically associated with cardiovascular disease and type 2 diabetes. In addition, the scientists found that a diet with an increased proportion of unsaturated fatty acids leads to a reduction in risk-associated lipids and an increase in low-risk lipids.
