Physician Reluctance To Discuss Anal Sex Puts Patients At Risk

Aug 12 2022 - 09:08
Hot on the heels of COVID-19, Monkeypox is in the news for an alarming spread among people who engage in risky sexual behavior, because it is transmitted primarily through direct contact with infectious sores, scabs, or body fluids.

Healthcare professionals, particularly those in general practice, gastroenterology, and colorectal surgery, are going to need to discuss sexual behavior to make patients better informed. A new analysis of survey results finds that applies to young heterosexual women as well.

AI Algorithm Detects Brain Abnormalities - And May Help On The Road To Curing Epilepsy

Aug 12 2022 - 09:08
The Multicentre Epilepsy Lesion Detection project (MELD) used over 1,000 patient MRI scans from 22 global epilepsy centers to develop an algorithm which provides reports of where abnormalities are in cases of drug-resistant focal cortical dysplasia (FCD) – a leading cause of epilepsy.

Around 1 percent of the world’s population have the serious neurological condition epilepsy, that is characterized by frequent seizures. While drugs treatments are available for the majority of people with epilepsy, 20 to 30 percent do not respond to medications.

Exploiting Nuisances

Aug 12 2022 - 08:08
Today I am back from one of the most interesting workshops I ever attended to, and I wish to share some thoughts I had on possible ways to enhance our research of new ideas for future particle detectors with you. Those ideas come from discussions with other participants to the workshop, or just from re-digesting things I have been pondering over for a while.

Self-Pollinating Plant Has Loss Of Genetic Variation Without External Pollinators

Aug 10 2022 - 08:08
An experiment found that selfing” monkeyflower plants lost 13 percent to 24 percent of their genetic variation compared to another group that were propagated by bumble bees. 

Genetic variation is important to respond to changes in nature or the overall environment. The good news is that they used bumblebees and though they claim they are in decline, evidence does not show that, so the plants are not at short term risk. Even better, pollination is not done by bumblebees alone, there are over 25,000 species of just bees, and lots of other insects pollinate. An experiment outside a closed greenhouse would show that.

COVID-19: Paying People To Stay Home Helped Mental Health – But Not As Much As Working

Aug 09 2022 - 17:08

In March 2020, a few days before lockdown was introduced, the UK government launched the Coronavirus Job Retention Scheme, widely referred to as “furlough”. This scheme provided employees who were unable to work due to the pandemic with 80% of their pay (capped at £2,500 per month).

Vaping Isn't A Gateway To Smoking But Marijuana May Be A Gateway To Vaping

Aug 09 2022 - 17:08
WNBA star Brittney Griner is in a Russian jail because the laws of the country you enter no matter what country you live in. A visitor to the US with banned substances is going to jail the same way. Yet to many Americans, what she had is no problem. She was not smuggling drugs, she had cannabis oil used for vaping.

In that, she is hardy alone. Much like medical marijuana prescriptions were overwhelmingly obtained by young men while pain prescriptions are overwhelmingly for older women, there is a clear demographic who take up vaping for the cannabis, not to quit smoking or reduce harm by replacing carcinogenic smoke with nicotine vapor.

Follicle Stimulating Hormone May Increase Risk Of Obesity After Menopause

Aug 09 2022 - 14:08
Obesity is correlated to risk for breast cancer after menopause and new study suggests that this adiposity is related to the follicle stimulating hormone (FSH).

It is only an observational study, in the exploratory section and not causal, but the authors say their examination of  hormone levels from samples stored in a Women’s Health Initiative biobank is the largest study of its kind in older women.

A hormone released by the pituitary gland, FSH plays an important role in female development and reproduction by stimulating growth of the ovarian follicle before ovulation.

Food Science: New Fix For Nature's Wasting Of Water During Photosynthesis

Aug 08 2022 - 15:08

The researchers confirmed there is a system in place that is working to limit the amount of water being lost from the leaf, but what’s causing it is not settled. They believe that water conduits, called aquaporins, located in the cell membranes are responsible.

Lightning, Not Utilities, Are Major Cause Of California Fires

Aug 08 2022 - 13:08
California is primarily a desert and with no way to generate enough of its own electricity, the state must run power lines from other states through dry areas to keep a growing population in air conditioning. When wildfires occur the state routinely blames utilities and since utilities are created and managed by government fiat, utilities rarely note that they are not allowed to own power lines in many cases, and environmental laws restrict clearing trees and brush near them. The state instead sues, gets a win in a politically sympathetic court, the utility goes into bankruptcy and then emerges and the whole process starts over.

About Taiwan

Aug 06 2022 - 20:08

“We got rich fast here,” a man in Beijing told me, “and we’re fast getting richer. Those lazy Taiwanese aren’t getting richer at all.” It is fashionable on the mainland to diss Taiwan, but – as I was too polite to inform my interlocutor – Taiwan residents have created a fine civil society and have learned to get along well with each other, tasks that are much harder than just getting rich.

Previously Unknown Mechanism In Plant Meiosis Discovered

Thylakoids May Be A New Way To Optimize Plants For Harsh Growing Conditions

Aug 01 2022 - 17:08
Countries where regressive policies toward science have banned modern technologies like genetic engineering are also overwhelmingly unable to feed themselves. Some European countries not only prevent much of Africa from feeding themselves, they ban imports by former colonies that don't do as they are told.

A new breakthrough may mean genetic optimization that green NGOs won't have a reason to ban, like mutagenesis genetic engineering and copper sulfate pesticides, which are currently organic certified.

Gene Mutations In Retinal Lesions From Vitelliform Macular Dystrophy Found

Jul 28 2022 - 10:07
Multimodal adaptive optics imaging has revealed photoreceptor and retinal pigment epithelium relationships in eyes with vitelliform macular dystrophy.

 Vitelliform macular dystrophy (VMD) is an inherited genetic disease that causes progressive vision loss through degeneration of the light-sensing retina. Genes implicated in VMD include BEST1, PRPH2, IMPG1, and IMPG2. Depending on the gene and mutation, age of onset and severity vary widely. All forms of the disease have in common a lesion in the central retina (macula) that looks like an egg yolk and is a build-up of toxic fatty material called lipofuscin. VMD affects about 1 in 5,500 Americans and there is currently no treatment for this condition.

The Magic Dimuon Decay Of B Mesons

Jul 28 2022 - 06:07
To appreciate what B mesons are, and what is the magic of their behaviour, which is the topic of this article, I need to give you a three-paragraph introduction below.

At the smallest distance scales, matter is made of quarks and leptons, which we consider as point-like objects endowed with different properties and interactions. Most of the matter around us is in fact made up of three-quark systems: protons and neutrons, organized in tightly packed nuclei kept together by the strong force; with electrons (which are the lightest charged leptons) orbiting around them thanks to the electromagnetic force attracting them to the protons.

COVID Variants And Transmission - 'Reff' May Be More Important Than R0

Jul 27 2022 - 09:07

During the pandemic we have all become familiar with a lot of epidemiological concepts.

One that was introduced to us early in 2020 is the “basic reproductive number”, or R0. This tells us about the intrinsic contagiousness of a virus, or its inherent capacity to be spread from one person to another in a particular population.

We also learned about the “effective reproductive number”, or Reff. This tells us about the rate at which a virus is actually spreading through that population.

With the emergence of BA.4/5, there has been some confusion around how these concepts help us to understand why one variant spreads faster than another.
