Dr Robert Bryant – Dr Langdon Martin | Reducing the Carbon Footprint of Cattle Farming with Leftover Brewer’s Yeast
Methane is one of the most potent greenhouse gases that contributes to the global climate crisis. As this gas is produced in the digestive systems of cattle, methane represents one of the greatest problems faced by the farming industry. Dr Robert Bryant, Dr Langdon Martin and their team at Warren Wilson College, North Carolina, propose an innovative feed supplement for cattle that helps to significantly reduce methane emissions: waste yeast from craft breweries. If used on a large scale, this new supplement could significantly decrease emissions associated with cattle farming, while also creating a new use for a waste product of the craft beer industry.
Savannas are characterised by the co-existence of two very different types of plants – trees and grasses. They may be open, with large swathes of grass and an occasional tree dotting the landscape, or closed with a near complete cover of trees and a sparse grass layer beneath. In drier parts of the world, drought may play an important role in determining the balance between the trees and grasses in savannas. Extreme droughts, which are likely to become more common with climate change, could permanently shift a closed savanna to an open one. Such changes would have significant consequences for the functioning of these ecosystems and the animals they support. Dr Anthony Swemmer of the South African Environmental Observation Network explored the impact of an unusually severe drought on trees in South Africa. His team’s research shows that the response of trees to drought depends on a suite of local factors.
Discovering new phases of matter and classifying such phases are among the most important goals in physics. In a new study, Dr Tie-Cheng Guo and Professor Li You at Tsinghua University in Beijing present a new methodology to discover new quantum phases of matter, using the concept of ‘time order’. Through identifying and defining quantum phases from this perspective, time order could become a new paradigm in physics, helping researchers to gain more insight into quantum many-body systems.
Dr Alejandro Estrada and Dr Paul A. Garber | The Importance of Indigenous Peoples in Safeguarding Earth’s Primates
Non-human primates play crucial roles in sustaining natural ecosystems worldwide. However, approximately 68% of primate species are now at risk of extinction, mainly due to agriculture and the depletion of natural resources. Dr Alejandro Estrada at the National Autonomous University of Mexico, Dr Paul A. Garber at the University of Illinois-Urbana, and a group of scientists from various parts of the world recently carried out a study to better understand the role that Indigenous Peoples play in the conservation of threatened primates.
