Published on Leave a comment on Study Finds Fewer Boys Born After Pregnancy Heat Stress

It is known that temperature during pregnancy can have an effect on the number of male vs female babies born (the sex-ratio) among animals. An interesting study suggests that this is also true for humans.

The study found that exposure to days with a temperature 20 degrees Celsius (68 degrees Fahrenheit) or higher during the nine months of pregnancy leads to fewer male births. While at first glance that doesn't seem so warm, these areas also had days 30 degrees Celsius (86 degrees Fahrenheit) and higher.

The study was done by linking data on 5 million live births in 33 sub-Saharan countries and India with temperature data. The researchers observed fewer male births after high first-trimester temperature exposure. This was consistent with increased spontaneous abortions due to mother's heat stress. This is especially true for mothers in rural areas, with little education. (No air conditioning!)

From Euronews: As temperatures rise, the number of male births is decreasing, study finds

When temperatures rise above 20°C, fewer baby boys are born compared to girls, a new study has found.

Researchers at the University of Oxford found that heat exposure can increase prenatal mortality in early pregnancy, particularly among males.

Do you wonder if there are any parasites in the fresh fish you're about to eat? How about in your sushi or sashimi? A recent study found that almost all tuna (53 skipjack tuna) caught recently off the cost of southern Brazil contained parasites.

While it is unknown what is in the tuna that you may be about to eat, the researchers say that cooking the fish kills all parasites. Parasites are also killed during canning. By the way, it is unknown what the fish from other parts of the world may contain.

From Science Alert: Scientists Find Parasites in Almost Every Fish From a Recent Tuna Haul – 96% Were Infected

A fatty tuna that is often used for sashimi or canning may be swimming with parasites more often than not.

When scientists at the Federal University of Santa Catarina in southern Brazil analyzed 53 locally caught fish, they found nearly all were contaminated by worms.

According to a brief communication published in Ocean and Coastal Research, the research team counted more than 1,600 little worms in total. Using powerful microscopy tools as aids, they found that the kidney and heart were the only organs free of parasites in every fish. Otherwise, the worms and their signs were everywhere. Of the 53-fish haul, 96 percent were infected by parasites.

Published on Leave a comment on August Set A New Record As the Hottest Month Globally

Once again, the global record for hottest month was broken this summer. August was the hottest month globally on record, and this past summer was the hottest on record for the lower 48 states (United States). .

What we are seeing is that month after month new heat records are being set, with the baseline being set higher and higher. And yet these are soon broken. Scientists agree that a big contributing factor is human caused climate change (due to burning of fossil fuels - gas, oil, coal). Are governments taking note and doing something? Hmmm...

Excerpts from NPR: This summer was hot. August shattered global heat records

If you thought this summer felt hotter than normal, you were right. Temperatures around the world were unusually warm, surpassing several heat records, including in the U.S.

The National Oceanic and Atmospheric Administration this week announced that for the Lower 48 states, this summer– from June to August– was the warmest in 132 years of record-keeping. ...continue reading "August Set A New Record As the Hottest Month Globally"

Published on Leave a comment on Simple Treatments May Work Best For Knee Arthritis Pain

Knee pain due to knee arthritis is something that many (most?) people complain about as they age. A recent study looking at what non-drug therapies helped people with knee pain found that some of the simplest treatments (knee braces, water-based therapy, exercise) worked best.

A review of 139 studies involving 9644 people and 12 therapeutic options (low level laser therapy, high intensity laser therapy, transcutaneous electrical nerve stimulation, interferential current, short wave diathermy, ultrasound, lateral wedged insole, knee brace, exercise, hydrotherapy (exercises done in warm water), kinesio taping and extracorporeal shock wave therapy) for knee arthritis was analyzed.

The researchers found that knee braces ranked highest overall for reducing pain, stiffness, and mobility problems. This was followed by water-based therapy was especially effective for pain, and regular exercise consistently improved both pain and physical movement. The high-tech approach of ultrasound was reported as the least effective, thus not recommended.

From Science Daily: Nearly 10,000 patients reveal what works best for knee arthritis pain relief

Knee braces, water therapy, and exercise may be among the most effective drug-free options for people with knee osteoarthritis, according to a large analysis published in the open-access journal PLOS One. The research was led by Yuan Luo of the First People's Hospital of Neijiang, China. ...continue reading "Simple Treatments May Work Best For Knee Arthritis Pain"

Do you trust that your drinking water is safe to drink? If the answer is no - you are absolutely correct in being suspicious. A recent ruling by a (Trump appointed) judge in Mississippi ruled that we do not have a right to clean water. Specifically, the US constitution offers no right to clean water or to truthful health information. What??!!

Published on Leave a comment on Stop Cold Sores In Their Tracks With Ice Cubes

Stop cold sores by icing them? Yes!

Years ago I read that applying ice cubes to an emerging cold sore can stop it dead in its tracks. Nowadays that method of dealing with cold sores (caused by herpes simplex virus) is not mentioned on medical sites. Yet my experience has been that applying ice and holding it on the emerging cold sore absolutely works.

The sore stops developing at the point when the ice is applied. When applied early in development the cold sore never fully emerges, and so the fluid filled blister and weeping stages never occur.

Instead, it will go directly to the scab stage, or even regress to nothing if you get it early enough. The key is to get ice directly on the spot before the sore fully erupts, and to press or hold the ice directly on it for lengthy periods of time - perhaps a total of 30 to 40 minutes (if it's very early in development) up to one hour. For best results, can do a second time in one day. Repeat on day 2 if needed or desired.

Method: Apply an ice cube directly on the area where the cold sore is emerging (but wrap part of it in a paper towel so you can hold it comfortably). Hold it on the spot till the ice cube melts. Then apply a second ice cube to the area until the ice melts. Perhaps even a third (or 4th?) ice cube. Yes, the skin will be a little red afterwards, but that soon goes away.

Big question: Would this method work for everyone? Don't know of any studies looking at this. But some people on Reddit mention successfully stopping cold sores by using ice cubes ("ice the cold sore"). Here and here and here. Some other comments from Redditt:

"I know this sounds crazy but ice will stop a cold sore in its tracks without fail for me! You have to get the ice on there as soon as you feel the tingle though because once it starts to break skin it's much harder to stop. Let an ice cube melt entirely on it, and then another. And maybe a third lol."

"100% works. Anyone not doing this is suffering for no reason. Ice ice ice it!"

"Ice it. Right when you feel it. It stops it from replicating. Stops it right in it's tracks. Won't even get any blisters. It's amazing!"

"Honestly I put ice in a ziploc bag and hold it up to the spot anytime I feel a cold sore coming, usually gets rid of it but only when you do it right when you feel it coming.

Published on Leave a comment on Hundreds Of Government Datasets Have Been Deleted or Altered

Can you trust government data these days? And what if you can't find government data anymore - that is, data that used to be easy to find, such as air pollution, climate change, health data, whether you live near hazardous chemicals, and certain medical topics? Well... it turns out that the current U.S. government has deleted or altered nearly 400 data sets since January 2025.

So what information can we now trust? It is interesting that the independent news site The Guardian is writing about this, but silence in most of the media in the US.  Ooops. Knowing what information or data has been altered or deleted is very important to know because the US federal government does not have to notify us that that are deleting or altering data sets.

To follow in depth go to the online tracker , the site put together by dataindex.us (the group of researchers and experts that have put together this information in one place). The list is not complete, so they also want YOU to notify them if you know of more deletions and alterations.

Published on Leave a comment on A Commonly Used Pesticide Is Linked to Thyroid Cancer
Turf Builder Weed and Feed (with 2,4-D)

Exposure to the weed-killer 2,4-D is very common. This pesticide has been used for many years starting with its use in Agent Orange decades ago, as an ingredient in the commonly used Weed and Feed for lawns, even on genetically engineered crops, and on and on. While the pesticide industry tells you it's safe, many studies have found that exposure to it can cause all sorts of health harms.

A recent study found that exposure to 2,4-D is linked to thyroid cancer in rural counties (where the pesticide is used the most). The researchers think that this may be occurring because 2,4-D is "an endocrine disruptor and may be toxic to the thyroid gland".  They also point out that biomonitoring studies find that in rural agricultural areas people (especially women and children) have higher amounts of 2,4-D in their urine.

As mentioned in the following article, other studies also find that 2,4-D exposure has thyroid effects. It also points out that one study found 2,4-D in the bodies of 1 in 3 Americans, and another study found the presence of both 2,4-D and dicamba (both herbicides) in all pregnant midwest women studied in 2020-2022.

While the United States EPA does not view 2,4-D as carcinogenic (cancer-causing), other countries and international organizations do.

Bottom line: To lower your own 2,4-D exposure, eat as many organic foods as possible, and don't use pesticides on your lawn. Organic crops and organic lawn care does not allow the use of 2,4-D.

Excerpts from Beyond Pesticides: Thyroid Cancer Associated With Exposure to the Weed Killer 2,4-D, Study Finds 

In a study of the herbicide 2,4-D and thyroid cancer in the U.S., researchers find that 2,4-D exposure is significantly associated with greater thyroid cancer incidence in rural counties. Utilizing incidence rates for thyroid cancer for 2017–2021 through the Centers for Disease Control and Prevention (CDC) database and county-level 2,4-D use data from the U.S. Geological Survey, this research, published in Endocrines, highlights a link between pesticide exposure—in areas where agricultural pesticide use is most concentrated—and disproportionate cancer risks. ...continue reading "A Commonly Used Pesticide Is Linked to Thyroid Cancer"

Published on Leave a comment on Military Veterans and ALS

Oops! Another choice of occupation may result in a higher rate of an illness - this time a higher rate of ALS (amyotrophic lateral sclerosis) in male veterans of certain branches of the military - the Air Force, Navy, and Coast Guard. But not the Army or Marines.

ALS is a progressive and fatal neurodegenerative disease. There is progressive loss of motor neurons, the nerve cells in the brain and spinal cord that control voluntary muscle movement and breathing.

The ALS study, led by researchers at Harvard T.H. Chan School of Public Health, included nearly 9.2 million male veterans who received care through the VHA between 2000 and 2024. Air Force veterans had a 29% higher rate of ALS, Coast Guard veterans  a 26% higher rate, and Navy veterans a 15% higher rate, when compared to Army veterans. Officers had a 64% higher rate than enlisted personnel.

The researchers also said that since ALS is rare and women make up a smaller share of the military population (just 18%) it is hard to assess what is going on with women. But among the women who were included, female officers faced a 72% higher risk compared with enlisted women

The big question is - what environmental exposures led to higher rates of ALS? Still unknown at this time. Some known risk factors are lead, pesticides, and other toxins.
