Link found between drought and HIV among women in less-developed countries — ScienceDaily

[email protected]_84

Current research predicts that by 2025, 1,800 million people are expected to be living in countries or regions with insufficient water resources, and models show increased severity of droughts in years to come. Food insecurity and other consequences of droughts will become intensified, influencing disease vulnerabilities among populations in less-developed countries. New research from Kelly Austin, associate professor of sociology at Lehigh University, explores how droughts shape gender inequalities in the HIV burden, indirectly through increased food insecurity.

The paper, “Drying Climates and Gender Suffering: Links Between Drought, Food Insecurity, and Women’s HIV in Less-Developed Countries,” is published in Social Indicators Research.

This study builds on previous attempts to explain women’s disproportionate share of global HIV cases through biological, cultural and socioeconomic inequalities by bringing the environment and climate-related disasters into the discussion.

“While many infectious diseases like HIV/AIDS do not have a direct link to the environment in

Pediatric genomic COVID-19 study suggests potential link between SARS-CoV-2 mutations and disease severity — ScienceDaily

[email protected]_84

When it comes to children, it is becoming clear that COVID-19 impacts them more than was initially realized. Yet there is relatively little information about SARS-CoV-2, the virus that causes the disease, in pediatric populations. Scientists at Children’s Hospital Los Angeles have just published the largest pediatric COVID-19 study to date, suggesting, for the first time, a possible link between specific viral mutations and severity of the disease.

COVID-19 is not a genetic disease, but genetics of the SARS-CoV-2 virus play an important role in its spread. Mutations — mistakes in the virus’ genome as it replicates — can affect how the virus transmits, and may play a role in disease severity. Understanding these links is critical to battling this pandemic.

“SARS-CoV-2 is genetically unstable,” says Xiaowu Gai, PhD, the Director of Bioinformatics at Children’s Hospital Los Angeles. “We tend to refer to ‘the virus,’ but when we think about

‘Kennedy’ host and panel break down hearing on Big Tech election interference and censorship

Twitter claims it has reversed its censorship of a link to the lawsuit filed by attorney Sidney Powell that seeks to change the outcome of Georgia’s 2020 election results.

The lawsuit, filed on Wednesday evening, alleges multiple constitutional violations, citing experts, fact witnesses and statistical improbabilities within the results. The plaintiffs seek to decertify the 2020 election results in the state and have Trump declared the winner.

“The URL referenced was mistakenly marked under our unsafe links policy — this action has now been reversed,” a Twitter spokesperson told FOX Business. The warning still appeared when FOX Business clicked on the link.

Twitter says it sometimes takes action to block links to content outside Twitter. Links are blocked if they are deemed to be malicious and used to steal personal information, spam that mislead people or

16-year-old cosmic mystery solved, revealing stellar missing link — ScienceDaily

[email protected]_84

In 2004, scientists with NASA’s space-based Galaxy Evolution Explorer (GALEX) spotted an object unlike any they’d seen before in our Milky Way galaxy: a large, faint blob of gas with a star at its center. Though it doesn’t actually emit light visible to the human eye, GALEX captured the blob in ultraviolet (UV) light and thus appeared blue in the images; subsequent observations also revealed a thick ring structure within it. So the team nicknamed it the Blue Ring Nebula. Over the next 16 years, they studied it with multiple Earth- and space-based telescopes, including W. M. Keck Observatory on Maunakea in Hawaii, but the more they learned, the more mysterious it seemed.

A new study published online on Nov. 18 in the journal Nature may have cracked the case. By applying cutting-edge theoretical models to the slew of data that has been collected on this object, the authors posit

Parasitic worms offer ‘the missing link’ on the dual nature of a key immune regulator — ScienceDaily

[email protected]_84

De’Broski Herbert has a philosophy that’s guided his career researching helminths, or parasitic worms, and their interaction with their hosts’ immune systems: “Follow the worm.”

“The mantra of my lab since its inception has been that parasitic worms manipulate their hosts in very interesting ways to maintain their survival,” says Herbert, an associate professor of pathobiology in Penn’s School of Veterinary Medicine. “SARS-CoV-2 doesn’t care about staying in your body very long because it is transmitted so easily. Worms aren’t spread so easily, so they have to figure out how to persist.”

That focus has revealed a key insight about an immune signaling molecule, the cytokine IL-33, that is important not only in parasite infections, but in a range of other health conditions, such as asthma, obesity, and eczema. In a new study published in Science Immunology, Herbert and colleagues made insights that explain how IL-33 can both help

Link between sleep apnea and increased risk of dementia — ScienceDaily

[email protected]_84

A new study by Monash University has found that obstructive sleep apnea (OSA) has been linked to an increased risk of dementia.

The study, published in the Journal of Alzheimer’s Disease, and led by Dr Melinda Jackson from the Turner Institute for Brain and Mental Health, found that severe OSA is linked to an increase in a protein, called beta-amyloid, that builds up on the walls of the arteries in the brain and increases the risk of dementia.

The study involved 34 individuals with recently diagnosed untreated OSA and 12 individuals who were asymptomatic for sleep disorders. It explored associations between brain amyloid burden using a PET brain scan, and measures of sleep, demographics and mood.

The OSA group recorded a higher amyloid burden, poorer sleep efficiency and less time spent in stage N3 sleep (a regenerative period where your body heals and repairs itself).

OSA is a common sleep

Researchers link Florida summertime rainfall with a warming Atlantic Ocean — ScienceDaily

[email protected]_84

A new study by researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science projects an increase in Florida’s late summertime rainfall with rising Atlantic Ocean temperatures.

Scientists have known for years that Florida receives more rainfall in decades when North Atlantic waters are warmer than average, but the UM research team wanted to learn more about this interaction to help communities prepare for a wetter future. This study showed that ocean temperatures are most influential on Florida precipitation in late summer, during the region’s highest high tide events.

The researchers used a suite of climate models to show that the link between ocean temperatures and rainfall only develops as a result of human influences on the climate system, such as greenhouse gas emissions and industrial pollution.

“We know that humans are continuing to make North Atlantic waters warmer, so we expect an increase in late

Mariah App, an augmented reality program, reveals haunting link of Met’s Sackler Wing to opioid crisis

[email protected]_84

The billionaire Sackler family is known for donating millions of dollars to museums and cultural institutions around the world. The Mariah App, however, calls attention to their ownership of Purdue Pharma, which they are relinquishing under a bankruptcy proposal. The pharmaceutical company made and marketed the prescription painkiller OxyContin.

Mariah Lotti was addicted to opioids and died of an overdose in 2011. She was 19.

Artists Adam DelMarcelle and Heather Snyder Quinn created the app as part of what they call a “virtual hacking of space with memorials to the countless lost hidden in plain sight.”

The artists didn’t actually hack the Met, but the Met wasn’t involved with the app, which superimposes Lotti’s story, and those of other people who died of opioid abuse, over the artifacts in the Met’s Sackler Wing. When users point their phone camera at different objects, information about the Sacklers, opioid abuse and its
