A new study led by researchers at the University of Houston suggests that a single molecule, derived from cholesterol, lurks inside your bloodstream and will increase your body fat, even if you don't eat a diet filled with red meat and fried food. That kind of diet, however, will increase the levels of this molecule and body weight, noted the researchers.

Professor of biology Michihisa Umetani said in the journal Endocrinology: "We found 27HC directly affects white fat tissue and increases body fat, even without eating the diet that increases body fat." Doctoral student Arvand Asghari also participated in the study.

Long term applications of the findings could lead researchers to a treatment that reduces the levels of 27HC. Because this molecule is linked to estrogen receptors, the researchers hope to develop a new therapeutic approach to treat cholesterol and/or estrogen receptor-mediated diseases such as cardiovascular diseases, osteoporosis, cancer and metabolic diseases. Men have lower levels of estrogen.

The world again registered its hottest day on record on Monday, July 22, inching past Sunday which had just taken the title, according to preliminary data from a European Union monitoring agency.
As heatwaves sizzled around the world and wildfires engulfed parts of the Mediterranean, Russia and Canada, the global average surface air temperature rose to 17.15 degrees Celsius (62.87 degrees Fahrenheit) on Monday. That was 0.06 C (0.11 F) higher than Sunday's record according to the EU's Copernicus Climate Change Service, which has tracked such data since 1940.
This includes temperatures in the Southern Hemisphere which is currently in winter, bringing down the worldwide average.
Scientists said it was possible that Tuesday or Wednesday of this week could again surpass Monday's record, as temperature peaks generally happen in clusters, Reuters reported.
The last record hot day was in July 2023, when the daily peak was broken across four consecutive days from July 3 through 6. Before that, it was set in August 2016.
What makes this year's record unusual is that unlike in 2023 and 2016, the world in April moved out of the El Nino climate pattern which generally amplifies global temperatures owing to warmer-than-usual waters in the Eastern Pacific.
Karsten Haustein, a climate scientist at Leipzig University in Germany, said it was remarkable that the record had been breached again now with the world well into the "neutral" phase of the El Nino-Southern Oscillation.
This points to the greater-than-ever influence of climate change, driven by the burning of fossil fuels, in boosting global temperatures.
"This past Monday might have set a new global record for warmest absolute global average temperature ever - by that I mean going back tens of thousands of years," Haustein said.
