Cattle are a major source of greenhouse gas emissions, mainly due to their methane-loaded burps. A detailed new study has found more evidence that feeding cows a small seaweed supplement can greatly reduce their methane emissions. Source of Article
There are energy sources all over the place, if you know where to look. Researchers at CUHK have now designed new modular nanogenerators that can harvest energy from various different types of motion, such as ocean waves or a person's body movements. Source of Article
Researchers studying hair loss Japan have shed yet more light on the topic, discovering a new mechanism by which dividing cells can drive hair follicles to exhaustion, subduing their regenerative abilities as we age. Source of Article
MIT engineers have found a new use for a common plastic, spinning polyethylene into fabric that can passively cool the wearer by allowing heat through and moisture to evaporate. The discovery could see waste plastic bags being turned into sportswear. Source of Article
There are untold energy sources all around us, if we can just figure out how to tap into them. Swiss researchers have now demonstrated an environmentally friendly way to make spongy wood flooring that can generate electricity with every step. Source of Article
In January scientists reported the detection of very low-frequency gravitational waves. Now astrophysicists have investigated two possible sources – the universe cooling down after the Big Bang, and a field of particles that could be dark matter. Source of Article
In case there was ever any doubt … atrocities are nothing new. Scientists have recently determined that piled human remains unearthed in what is now Potočani, Croatia, represent the earliest-known indiscriminate mass killing. Source of Article
Just like a tree trunk, the tusk of the narwhal acquires a new growth ring every year. Analyses of those rings have now revealed some interesting facts about the animals' diet, and about changes in their environment. Source of Article
How exactly supermassive black holes got so big remains a mystery, but a new study suggests they may have been born from supernovae of hypothetical, primordial stars far bigger than any around today. And we might soon be able to detect the leftovers. Source of Article
In the event of a global catastrophe, how would we protect the wide variety of plants and animals on Earth? A team of researchers has now proposed a “Noah’s Ark” on the Moon that stores millions of samples of seeds, spores, sperm and eggs. Source of Article
