Climate change affects nearly all life on Earth

MIAMI, United States (AFP) — Most life on Earth is already being changed by the warming climate, even though the rise in global temperature since pre-industrial times has been rather slight, researchers warned on Thursday. The study in the journal Science found that 82 percent of key ecological processes — including genetic diversity and migration patterns — are being altered by global warming. These effects extend to land, oceans and freshwater environments, even though temperatures have […]

Leprosy found in red squirrels of Britain, Ireland: study

by Kerry SHERIDAN MIAMI, United States (AFP) — Some red squirrels in Britain and Ireland are infected with the bacteria that causes leprosy in humans, though the risk of transmission to people is low, researchers said Thursday. Still, scientists were surprised to uncover signs of the infectious disease that ravaged Europe in medieval times but which has dramatically declined in the modern era. “This has never been observed before,” said Stewart Cole, a researcher with […]

Tobacco linked to 40 percent of US cancers

MIAMI, United States (AFP) — Tobacco use remains the most preventable cause of cancer, and 40 percent of diagnosed US cancer cases may have a link to its use, health authorities said Thursday. Lung cancer, acute myeloid leukemia, and tumors of the mouth and throat, voice box, esophagus, stomach, kidney, pancreas, liver, bladder, cervix, colon and rectum are all caused by tobacco use, according the report by the US Centers for Disease Control and Prevention.

Human antibody shields mouse foetuses against Zika

PARIS, France (AFP) – by Mariëtte Le Roux An antibody produced by the human body shielded unborn mice against Zika, a study said Monday, raising hopes for thwarting the virus known to cause brain damage in human foetuses. The antibody neutralised all known Zika strains in lab experiments, and “markedly reduced” virus levels in infected pregnant mice and their foetuses. “This is the first antiviral that has been shown to work in pregnancy to protect […]

300 million children breathe heavily toxic air: UNICEF

by Jean-Louis SANTINI WASHINGTON, United States (AFP) — Some 300 million children live with outdoor air so polluted it can cause serious physical damage, including harming their developing brains, the United Nations said in a study released Monday. Nearly one child in seven around the globe breathes outdoor air that is at least six times dirtier than international guidelines, according to the study by the UN Children’s Fund, which called air pollution a leading factor […]

Screening infants could prevent early heart attacks: study

MIAMI, United States (AFP) — Screening young children for high cholesterol at the same time as they receive routine vaccinations could prevent hundreds of heart attacks in young adults each year, researchers in Britain said Wednesday. Their study in the New England Journal of Medicine aimed to uncover a silent killer in young adults known as familial hypercholesterolemia (FH), a genetic disorder that often leads to early heart disease. FH runs in families, and if left […]

Pregnancy raises stroke risk in younger, not older women: study

MIAMI, United States (AFP) — Doctors have long warned women that getting pregnant later in life can raise the risk of stroke, but a study Monday suggested that actually, only young women face this increasing risk. The findings in the Journal of the American Medical Association (JAMA) Neurology compared stroke rates among pregnant and non-pregnant women of different age groups. Previous studies have focused on the rate of stroke among pregnant women of different ages […]

Babies should sleep in parents’ room first year: US doctors

by Kerry SHERIDAN MIAMI, United States (AFP) — To reduce the risk of sudden death, babies should sleep in the same room as their parents but in their own crib or bassinet for the first year of life, US doctors said Monday. The new policy statement by the American Academy of Pediatrics still says babies should sleep on their backs, on a clean surface free of toys and blankets, a guideline that has been in […]

Cancer ‘smoke alarm’ could aid early diagnosis

(Reuters) — A new blood test that acts as an early warning system for cancer is being developed by researchers at Swansea University. It works by detecting mutations in red blood cells in advance of cancer symptoms appearing, and could one day give GPs a simple, non-invasive way to screen patients before deciding whether further investigation is needed. While the research has so far focused just on cancer of the oesophagus, the team hopes it […]
