Long before humans planted crops like wheat or rice, ants were already farming. These tiny animals have been cultivating fungi for millions of years, developing a system that rivals our own agriculture in complexity. New research led by entomologist Ted Schultz from the Smithsonian’s National Museum of Natural History traces this practice back 66 million years, right after the asteroid that wiped out the dinosaurs. In a study, published earlier this month in Science, Schultz and his [...]

High blood pressure (hypertension) causes thickening of the blood vessels and hardening of the arteries (arteriosclerosis). A study conducted by Brazilian researchers has shown for the first time that a similar phenomenon occurs in the lungs. High blood pressure hardens the bronchi and increases airway resistance, impairing respiratory capacity. The study sample comprised 731 men and women over 60, both with and without high blood pressure. It was designed to investigate the effects of [...]

Extreme temperatures and humidity due to climate change could reduce the Amazon rainforest's ability to absorb the greenhouse gas methane by 70 percent, a study has found. The researchers said that under a warmer climate, the extreme rainfall and drought expected in the South American Amazon could impact net greenhouse gas emissions. Also known as the “lungs of the earth,” these rainforests are located mostly in Brazil, but also in Peru, Colombia, and Ecuador, and are [...]

Ants beat humans to farming by 66 million years, and they were good at it too The study shows that the asteroid impact created favourable conditions for fungi to thrive on decaying plant material, allowing ants to cultivate and farm them. Nearly 250 ant species across the Americas and the Caribbean practice fungus farming.

A new study published in the journal Science reveals that ants began farming fungi 66 million years ago, long before humans developed agriculture. The research, led by entomologist Ted Schultz at the Smithsonian's National Museum of Natural History, traces the origins of this farming behaviour to the aftermath of the asteroid impact that wiped out the dinosaurs. Scientists discovered this ancient practice through extensive genetic analysis, sequencing data from 475 fungal species and [...]

A new study has found that high blood pressure can impair one’s breathing capacity by hardening the airways in the respiratory system, thereby increasing resistance. The study was a study published in the journal Advances in Respiratory Medicine and conducted by researchers from the Federal University of Sao Paulo, Brazil. The study, however, found that being physically active can help by improving the functioning of respiratory muscles, resulting in better coordination between [...]

NEW DELHI: Extreme temperatures and humidity driven by climate change could reduce the Amazon rainforest's capacity to absorb the greenhouse gas methane by 70 per cent, a study has found. Researchers said that under a warmer climate, the extreme rainfall and droughts projected for South America's Amazon could impact its net greenhouse gas emissions. Often referred to as the 'lungs of the planet', the tropical rainforest lies majorly in Brazil, with parts in Peru, Colombia, [...]

High blood pressure impairs one's breathing capacity by hardening the airways in the respiratory system, thereby increasing resistance, a study has found. However, being physically active can help by improving the functioning of respiratory muscles, resulting in better coordination between ventilation and blood flow in the lungs, researchers from the federal University of Sao Paulo, Brazil, found. Hypertension, in which one's blood pressure remains unusually high, is known to [...]
