Heat advisory issued for 11 US states: Record-high minimum, overnight temperatures this week
According to a USA Today report, temperature highs across the region are soaring well into the 90s and beyond. The heat index values are reaching 110 to 115 degrees Fahrenheit in some areas, including St Louis, Little Rock, and Chicago. The heat index, which accounts for humidity, makes temperatures feel significantly hotter and increases the risk of heat-related illnesses.
Where is the heat most severe?
Another Newsweek report stated that the states under heat advisories or excessive heat warnings are: Michigan, Wisconsin, Illinois, Indiana, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana, and Alabama.
In these areas, the overnight temperatures remain in the upper 70s or low 80s. This makes recovery from daytime heat nearly impossible, especially for those without air conditioning.

Night offers no relief either
AccuWeather meteorologist Alex DaSilva, according to Newsweek report, said that record-high minimum temperatures, the highest overnight lows ever recorded, are expected across multiple states. The humidity and urban infrastructure mean night time temperatures would not be falling below 80°F. This will significantly compound health risks.
DaSilva warned that this kind of heat could be deadly and added that vulnerable populations like the elderly, children, and those without access to cooling are especially at risk.
Why it matters?
The Centers for Disease Control and Prevention (CDC) and NWS use a tool called HeatRisk to monitor health threats from extreme heat. According to a Yahoo report, parts of the Midwest and the Deep South have reached Level 3 and Level 4 alerts. Hospitals are already seeing increased ER visits due to heat exhaustion, dehydration, and heatstroke.

Old Farmer's Almanac prediction for Fall 2025 across the US revealed
With extreme summer heat gripping millions across the United States, many are curious about what fall will bring. According to The Old Farmer's Almanac, the nation will witness a warmer-than-normal autumn, particularly in the western and southern US. Published annually since 1792, the Almanac relies on a mix of solar science, climatology, and meteorology to craft its long-range forecasts. On July 11, 2025, it released its weather outlook, and it is urging Americans not to pack away their fans just yet, per Newsweek. The Old Farmer's Almanac predicts that fall 2025 will have above-average temperatures in many parts of the US.(Representative image/Unsplash) Also read: Heat advisory issued for 11 US states: Record-high minimum, overnight temperatures this week Old Farmer's Almanac fall 2025 prediction According to Newsweek, the Almanac forecast above-average temperatures in key areas, including the Atlantic Corridor, Southeast, Florida, Deep South, Heartland, Texas-Oklahoma, High Plains, Intermountain West, Pacific Northwest, Pacific Southwest, and Alaska. It added that even the pumpkin patch visits could likely be sweltering this year. It added that precipitation is expected to be below normal across much of the US, particularly from California to Florida and up through Maine, with the High Plains and Pacific Northwest as exceptions. Cooler, colorful fall ahead in Northeast and Appalachians According to another Fox News report, not all regions will feel the heat. It is expected to be cooler and drier in areas like the Northeast, Appalachians, Lower Lakes, Ohio Valley, and Upper Midwest. In New England, these lower temperatures and reduced rainfall could create beautiful fall foliage. A Fox News report, referencing the Almanac, states that the Northeast may see below-average rainfall and average temperatures of 59°F in September and 46°F in October. The Appalachians' average temperature for the two months will be 65°F and 53°F, respectively. The Southeastern US and Florida will be warmer and drier than usual, with September temperature averaging 78–82°F. Lastly, the Pacific Northwest is expected to be warmer overall, with wetter conditions expected in October. Also read: New study reveals the date the universe will die. It's sooner than you think Hurricane season is not over yet The Almanac, however, cautioned that the 2025 Atlantic hurricane season, which officially ends in November, will feature above-normal activity with a 'high count of named systems'. NOAA's outlook: A mixed forecast The Fox News report stated that despite the Almanac projecting cooler conditions in the Northeast, the National Oceanic and Atmospheric Administration (NOAA) disagrees. NOAA's 90-day outlook showed high confidence in the warmer-than-normal fall in New England, citing above-average Atlantic Ocean temperatures. When it comes to rainfall predictions, NOAA and the Old Farmer's Almanac have both agreements and differences. NOAA forecasted wetter-than-usual conditions along the Eastern Seaboard, whereas Almanac predicted a drier fall for the same region. However, both align in projecting dry weather in the southern Plains and the Rockies. Their predictions diverge on Northern Plains where NOAA says conditions will be normal or drier but Almanac anticipated a wetter-than-average season. FAQs: Q: What is The Old Farmer's Almanac? A: It is the oldest continuously published periodical in the US, offering weather forecasts, astronomical data and seasonal advice since 1792. Q: What regions will be hottest this fall? A: Much of the western and southern US, including the Southeast, Pacific Northwest, and Intermountain West. Q: Will fall foliage be better this year? A: Yes, especially in the Northeast, where cooler temps and dry conditions may lead to more vivid colors. Q: What does NOAA predict for fall 2025? A: NOAA forecasts a warmer fall in the Northeast (opposite of the Almanac) and wetter conditions along the East Coast. Q: How accurate is The Old Farmer's Almanac? A: While not scientifically peer-reviewed, the Almanac claims 80 per cent historical accuracy, though independent studies suggest it's closer to 50–60 per cent.

130 million Americans under heat alerts: These 11 states are most affected
A relentless and expanding heat wave is impacting large swathes of the United States, with over 130 million Americans currently under Extreme Heat Warnings and Heat Advisories, according to the National Weather Service (NWS). As per a report in Newsweek, the brunt of the heat is being felt across 11 states — Michigan, Wisconsin, Illinois, Indiana, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana, and Alabama — where overnight temperatures are hovering in the upper 70s to low 80s, providing little to no relief from daytime extremes. The heat wave is driven by a persistent upper-level high-pressure system, commonly referred to as a heat dome, anchored over the eastern US. The NWS warns that this dome is pushing heat indices between 100°F and 105°F, with some regions in the Lower Mississippi Valley reaching 110°F or higher. In these areas, including parts of Arkansas, Mississippi, and Louisiana, Extreme Heat Warnings have been issued. "Recovery from daytime heat is nearly impossible, especially for those without air conditioning," AccuWeather Meteorologist Alex DaSilva told Newsweek, stressing the heightened risk of dehydration and heat-related illnesses. AccuWeather's latest forecast underscores the danger, projecting that more than 100 million people will face daily RealFeel® Temperatures of 100°F or more through the end of July. In parts of Oklahoma, Arkansas, Missouri, Illinois, Indiana, and Tennessee, RealFeel values are expected to soar between 110°F and 115°F due to the mix of extreme heat, high humidity, and minimal wind. 'This level of heat can be dangerous for many, particularly those exposed for extended periods,' said AccuWeather Senior Meteorologist Brett Anderson. He added that urban areas may not cool below 80°F at night, making sleep difficult and increasing the risk of heat exhaustion.

US Scientists discover new early warning sign for deadly pancreatic cancer
With 508,533 new cases and 505,752 deaths worldwide in 2021, pancreatic cancer remains a significant global health challenge with increasing incidence and mortality rates. Pancreatic cancer is often considered deadly due to its tendency to be diagnosed at a late stage, its aggressive nature, and the lack of effective treatments for advanced cases. However, may soon gain a powerful new ally in the battle against this cancer: a biological 'early warning' system that can signal the presence of precancerous pancreatic cells. Researchers at the University of California, San Diego, have uncovered a crucial link between inflammation, cellular stress, and the development of pancreatic ductal adenocarcinoma (PDAC), the most common and aggressive type of pancreatic cancer. What is pancreatic cancer? Pancreatic cancer is a disease in which malignant (cancerous) cells form in the tissues of the pancreas. The pancreas is a gland located behind the stomach that plays a crucial role in digestion and blood sugar regulation by producing enzymes and hormones. While the exact causes are not always clear, risk factors include smoking, family history of pancreatic cancer, long-standing type 2 diabetes, and chronic pancreatitis. Pancreatic cancer is often difficult to diagnose early because symptoms may be subtle or absent in the early stages. The deadliness of PDAC Pancreatic ductal adenocarcinoma (PDAC) originates in the small ducts of the pancreas and carries an incredibly grim prognosis. The average five-year survival rate is less than 10%. According to 2023 estimates, over 62,000 new cases of pancreatic cancer were diagnosed in the US alone. Because it usually shows no symptoms in early stages, PDAC is typically detected only after it has spread, making it hard to treat and nearly impossible to cure. Scientists have long known that inflammation and cellular stress are involved in the growth and spread of pancreatic cancer. But the exact mechanism remained unclear until now. The silver lining In a new study, the UC San Diego team focused on a protein called STAT3 (signal transducer and activator of transcription 3), which is activated under stressful or inflammatory conditions in the body. Once turned on, STAT3 triggers a chain of biological reactions that help tumors grow, adapt, resist treatment, and spread. David Cheresh, a pathologist and co-author of the study, told Newsweek, 'Given the fact that STAT3 plays such an important role in many cancers and the fact that it controls so many genes prompted us to drill down on which genes in particular are associated with cancer development, progression, and drug resistance.' The team also discovered that under low oxygen conditions and inflammation, both common in cancer, STAT3 activates a gene called Integrin β3 (ITGB3) in pancreas cells. This gene speeds up tumor growth and helps cancer spread faster. Even more concerning, they found that common treatments like chemotherapy can also trigger STAT3, which may explain why some tumors become resistant over time. However, the good news is, when researchers blocked STAT3's pathway, they were able to delay the development of tumors, offering a potential new direction for future therapies. The STRESS UP gene signature Through this work, the scientists identified 10 genes, including ITGB3, that STAT3 turns on during stress. Together, they form what the team calls the "STRESS UP" signature, a genetic fingerprint of precancerous activity. As per Cheresh, 'A significant number of patients are what we refer to as 'inducible' for these STRESS UP genes, including ITGB3.' But why is that important? Because it could help doctors predict which patients are likely to develop pancreatic cancer and how aggressive that cancer might become. It could also help determine who is more likely to respond to current treatments. Cheresh added, 'Having knowledge of this gene signature in patients could be valuable since there are known drugs on the market for other diseases that block STAT3 activation and thereby inhibit the expression of the STRESS UP genes in cancer cells.' The importance of early detection (and personalized treatment) The research suggests that STRESS UP could play a role at every stage of pancreatic cancer, from the earliest precancerous lesions to fully drug-resistant tumors and even those that have spread to other organs. According to Cheresh, 'We observed that the STRESS UP gene signature is linked to various critical stages of cancer development including: tumor initiation as precancerous lesions develop into actual tumors, as tumors develop drug resistance, and as tumors develop an invasive or metastatic behavior [when cancer spreads].' The researchers are now examining each of the 10 genes in the STRESS UP signature more closely to develop targeted therapies. One such therapy is already in early clinical trials for patients with drug-resistant cancers. Cheresh explained, 'We are now examining each of these STRESS UP genes for their specific role in the development and progression of cancer with the hope that new specific therapies can be developed. We already have one such therapeutic just now entering clinical trials for patients with drug-resistant cancers.' World Lung Cancer Day 2024: Combating The Deadly Disease With Advanced Treatments
