SoundWatch Alerts Deaf Users of Nearby Activity
Researchers at the University of Washington have developed a watch that can monitor a user’s environment for important sounds, such as a fire alarm or a microwave beeping, identify the sounds, and then inform the user through a subtle vibration.
“This technology provides people with a way to experience sounds that require an action – such as getting food from the microwave when it beeps. But these devices can also enhance people’s experiences and help them feel more connected to the world,” said Dhruv Jain, a researcher involved in the study, who is himself hard of hearing. “I use the wat...

Wednesday Bible Study: Shoah
I was originally going to title this post res ipsa loquitur because I didn ' t think I really needed to comment. You are commanded to read the whole thing. I do however want to make a few points about this.1) Moses ismarriedto a Midianite woman. There is evidently nothing wrong with that. She has several sisters. Her father was Moses ' s confidante and counselor. I wonder how she felt about all this.2) The incident which precipitated this, described in Chapter 25, made no mention of Balaam. All of a sudden he gets the blame, which seems strange since he was totally respectful of Yahweh and predicted that the Israelites wou...

Towards a More Sensitive Blood Test for the Earlier Stages of Alzheimer's Disease
The onset of Alzheimer's disease is preceded by years of slowly growing levels of amyloid-β aggregates in the brain. There is an equilibrium between amyloid-β in the brain and amyloid-β in the bloodstream, and so the research community has worked towards blood tests that can determine who is at risk of developing the condition. This goal is complicated by the sensitivity required, given the low levels of amyloid-β in blood samples, but the results here suggest that this problem may be sufficiently well solved to proceed towards an widely used assay. While the failure of clinical trials testing amyloid-clearing immunoth...

Fight Aging! Newsletter, August 3rd 2020
In this study, we examined the effects of oxytocin on the Aβ-induced impairment of synaptic plasticity in mice.
To investigate the effect of oxytocin on synaptic plasticity, we prepared acute hippocampal slices for extracellular recording and assessed long-term potentiation (LTP) with perfusion of the Aβ active fragment (Aβ25-35) in the absence and presence of oxytocin. We found that oxytocin reversed the impairment of LTP induced by Aβ25-35 perfusion in the mouse hippocampus. These effects were blocked by pretreatment with the selective oxytocin receptor antagonist L-368,899. Furthermore, the treatment with the...

A Genomic Search for Longevity-Associated Genes Points to Iron Metabolism in Human Aging
As a general rule, one should be skeptical about any and all single studies that identify longevity-associated genes from human data. Typically the results cannot be replicated in different study populations, and the effect sizes are in any case small. Identified gene variants confer only small changes in the odds of reaching a given age. Only a handful of gene variants show up reliably in multiple studies carried out in different human populations. So, unfortunately, however interesting or novel the data in a new study, such as the association of longevity with maintenance of normal iron levels noted in today's open acces...

When Life Isn ’ t About Conquering the Next Big Challenge
“Everyone wants to live on top of the mountain, but all the happiness and growth occurs while you’re climbing it.” – Andy Rooney
Three months ago, I was blessed with an awesome opportunity — a free weekend break to Snowdonia, Wales.
Having experienced chronic health conditions for the past six years of my life, I had been hibernating.
My days were a black-and-white routine: wake up, drink a smoothie mix, go to work, meditate, come home, lie down, eat, sleep. Yet, my mind was always so busy filled with endless tasks, big dreams, and an expanding sense of pressure as I craved more than what I had.
W...

Mechanically Stimulating Neurons Using Magnetic Nanodiscs
Electrical stimulation and chemical pharmaceuticals are the two ways that doctors and scientists routinely use to manipulate neural cells. Chemicals have their side effects, are slow to take effect, and are usually systemically delivered, while electrical stimulation usually requires invasive wires, is limited in its resolution, and is nearly impossible to administer within certain parts of the brain. Now, researchers at MIT have developed a new way to stimulate neurons that may open up new possibilities for research and clinical practice.
With the knowledge that neurons are sensitive to mechanical forces, including bei...

Tinted sunscreens: Benefits beyond an attractive glow
Tinted sunscreens are having a moment. These mineral-based sunscreen formulations have an added color base that can help even out skin tone while protecting your skin. And thanks to their ability to block visible light, they may help certain skin conditions. Could the days of unsightly sunscreen residue be in your past?
What is visible light, and how can it affect your skin?
Ultraviolet (UV) radiation and visible light are both part of the electromagnetic spectrum. UV radiation is composed of three different wavelengths: UVA, UVB, and UVC. UVC is mostly absorbed by the ozone layer, so UVA and UVB are the primary wavelength...

Veterans Affairs OIG Issues Caution on Goals of Care Compliance
The Veterans Affairs Office of Inspector General just released an inspection report of the Oscar G. Johnson VA Medical Center in Iron Mountain, Michigan. Care coordination concerning life-sustaining treatment decisions was one of the four focus areas.
VHA requires practitioners to initiate goals of care conversations with high-risk patients—including hospice patients or their surrogates—within a time frame that meets the medical needs of the patient or at the time of a triggering event. The GOC conversations are discussion between a healthcare provider and a patient or surrogate to help define the patient&...

Can a daily pill lighten heavy menstrual bleeding caused by fibroids?
Fibroids are generally benign (not cancerous) tumors that form within the tissues of the uterus. They are very common in reproductive-age women: studies report that up to 70% of white women and 80% of Black women may develop fibroids by age 50. And research suggests Black women are more likely to experience severe or very severe symptoms related to fibroids, such as heavy and sometimes prolonged monthly periods.
In some cases, women seek medical care due to menstrual bleeding so heavy that they develop anemia and require iron supplements or, much more rarely, blood transfusions. The FDA recently approved new medicine, take...

Wednesday Bible Study: God, the compassionate, the merciful?
Leviticus 26 is a structural underpinning of the Tanakh, and for better or for worse, of Zionism. Before I say anything about that, it is also the most succinct and clear description of the character of Yahweh. He is not benevolent, or merciful. He doesn ' t love humanity or even his chosen people. He demands to be worshiped and obeyed. That is all he cares about. While he has disgorged a torrent of commandments so far, the most often repeated, and reiterated here again for the greatest emphasis, are that he be the exclusive object of worship and that he be worshiped according to the rituals he specifies -- keeping the sab...

Has the Federal Government Preserved U.S. Shipbuilding Vitality? Or Sapped it?
Colin GrabowA recentNew York Timesfeature about the construction of containerships contains the following passage regarding the state of the U.S. shipbuilding industry:In the United States, large shipyards have been on the decline for decades, losing out on orders for massive commercial ships to cheaper foreign competition. Today, more than 90 percent of global shipbuilding takes place in just three countries: China, South Korea and Japan. What industry does remain in the United States is supported by the federal government, which orders American ‐made ships of all kinds, from Coast Guard cutters to naval aircraft car...
