Toxic chemicals may be behind the rising number of children with autism, attention-deficit hyperactivity disorder and dyslexia, U.S. researchers say.
Co-authors Philippe Grandjean, adjunct professor of environmental health at the Harvard School of Public Health in Boston, and Philip Landrigan, dean of the Icahn School of Medicine at Mount Sinai in New York, said the study outlines possible links between newly recognized neurotoxicants and negative health effects on children, including:
-- Manganese associated with diminished intellectual function and impaired motor skills.
-- Solvents linked to hyperactivity and aggressive behavior.
-- Certain types of pesticides might cause cognitive delays.

5 Messed-Up Things That Are In Your Food
Many of these ingredients are banned in Europe, but here in the good old USA you'll find them on your dinner plate. Many of these ingredients are banned in Europe, but here in the good old USA you'll find them on your dinner plate.
1. Azodicarbonamide in Bread
Until a month ago, few had heard of this "dough conditioner," intended to provide strength and improve elasticity. Like pink slime, it was azodicarbonamide's industrial overtones that drove indignation—it's "the same chemical used to make yoga mats, shoe soles, and other rubbery objects," wrote food blogger Vani Hari in a successful petition to get Subway to remove the substance from its baked products.
Vitamin C keeps cancer at bay, US research suggests
High-dose vitamin C can boost the cancer-killing effect of chemotherapy in the lab and mice, research suggests.
Given by injection, it could potentially be a safe, effective and low-cost treatment for ovarian and other cancers, say US scientists. Reporting in Science Translational Medicine, they call for large-scale government clinical trials.
Pharmaceutical companies are unlikely to run trials, as vitamins cannot be patented.
New cancer cases worldwide expected to skyrocket
The incidence of cancer worldwide is growing at an alarming pace, and there is an urgent need to implement strategies to prevent and curb the disease, according to a report from the World Health Organization.
New cancer cases will skyrocket globally from an estimated 14 million in 2012 to 22 million new cases a year within the next two decades, the report says. During that same period, cancer deaths are predicted to rise from an estimated 8.2 million annually to 13 million a year.
Cancer cases 'set to rise by half by 2030': UN
New cases of cancer will rise by half by 2030, reaching 21.6 million per year compared to 14 million in 2012, the UN said on Monday in a global analysis of the scourge.
Cancer deaths, meanwhile, will likely rise from 8.2 million to 13 million per year as the world's population grows and ages and more people adopt risky lifestyle habits, said the report compiled by the International Agency for Research on Cancer (IARC).
It took aim at Big Tobacco, saying its sales drive was "inextricably linked" to a likely surge in lung cancer.
Antibiotic 'smart bomb' can target bad bacteria
Researchers have developed smart antibiotics that target specific bacteria and sever their DNA, thereby eliminating multi-drug resistant bacteria.
The new approach, published online in the journal mBio, uses the bacterial immune system, called the CRISPR-Cas system. This immune system protects the bacteria by creating strands of RNA called CRISPR RNAs, which match the DNA of the invader and then unleash proteins to cut the invader's DNA.
Researchers devised a way to make these CRISPR RNAs target the DNA sequences of the bacteria, causing bacterial suicide when the Cas proteins begin to attack the bacteria's DNA.
Ten-minute online test can help estimate Alzheimer's risk
Many risk factors for Alzheimer's disease are linked to lifestyle or environment and the risk can be decreased at all ages, researchers in Australia say.
Lead researcher Professor Kaarin Anstey of the Australian National University in Canberra said a free 10-minute online test developed by ANU researchers is helping people assess their risk of developing Alzheimer's disease.
