Lead poisoning
Lead poisoning is a condition, also known as plumbism or painter's colic, caused by increased blood serum lead levels. The symptoms of lead poisoning include neurological problems, such as reduced IQ, nausea, abdominal pain, irritability, insomnia, excess lethargy or hyperactivity, headache and, in extreme cases, seizure and coma. There are also associated gastrointestinal problems, such as constipation, diarrhea, abdominal pain, vomiting, poor appetite, weight loss. Other associated affects are anemia, kidney problems, and reproductive problems. In humans, lead toxicity often causes the formation of bluish line along the gums, which is known as the "Burtons's line."

Dec. 26, 2025 Scientists discovered that common food emulsifiers consumed by mother mice altered their offspring’s gut microbiome from the very first weeks of life. These changes interfered with normal immune system training, leading to long-term inflammation. ...
Dec. 25, 2025 A new study suggests temporal lobe epilepsy may be linked to early aging of certain brain cells. When researchers removed these aging cells in mice, seizures dropped, memory improved, and some animals avoided epilepsy altogether. The treatment used ...
Dec. 25, 2025 Tramadol, a popular opioid often seen as a “safer” painkiller, may not live up to its reputation. A large analysis of clinical trials found that while it does reduce chronic pain, the relief is modest—so small that many patients likely ...
Dec. 25, 2025 A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation and starving brain tissue. When the missing ...
Dec. 24, 2025 Alzheimer’s has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and restoring that balance can reverse damage, even in ...
Dec. 24, 2025 A four–amino acid peptide called CAQK has shown powerful brain-protective effects in animal models of traumatic brain injury. Delivered through a standard IV, it zeroes in on injured brain tissue, calming inflammation and reducing cell death while ...
Dec. 24, 2025 Researchers have created tiny metal-based particles that push cancer cells over the edge while leaving healthy cells mostly unharmed. The particles work by increasing internal stress in cancer cells until they trigger their own shutdown process. In ...
Dec. 23, 2025 Scientists studying thousands of rats discovered that gut bacteria are shaped by both personal genetics and the genetics of social partners. Some genes promote certain microbes that can spread between individuals living together. When researchers ...
Dec. 23, 2025 Scientists at MIT and Stanford have unveiled a promising new way to help the immune system recognize and attack cancer cells more effectively. Their strategy targets a hidden “off switch” that tumors use to stay invisible to immune ...
