Goats can probably distinguish subtle emotional changes in the calls of other goats, according to a new study led by Queen Mary University of London.
The researchers measured behavioural and physiological changes in goats to determine if they can differentiate between calls linked to positive and negative emotions.
They found that when the emotion of a call changed, the likeliness of the goats to look towards the source of the sound also changed suggesting that they can distinguish the emotional content of calls of another goat.
A new study conducted by researchers in Leicester and Nottingham has shown the potential for a new blood test to not only diagnose human tuberculosis (TB) but also identify those at most risk of developing the disease, according to findings published in medical journal Clinical Infectious Diseases.
LOGAN, UTAH -- The 2019 Tour de France has just begun. As 190 riders speed through the streets of France, spectators will marvel at the tightly-packed formation of cyclists known as the peloton. Fans will argue that a peloton creates an aerodynamic advantage, allowing riders to conserve energy throughout the grueling three-week race.
Philadelphia, July 10, 2019 - CD8+ cytotoxic T lymphocytes can kill host cells infected with various microorganisms as well as single individual cancer cells through direct cell-to-cell contact, but their ability to destroy a target of large mass remains unexplored.
A healthy diet rich in fibre is generally recommended, but new research shows it could be even more important during pregnancy to promote the wellbeing of the mother and child.
Plant-based fibre is broken down in the gut by bacteria into factors that influence the immune system.
Researchers from the University of Sydney's Charles Perkins Centre, the Barwon Infant Study from Deakin University, Monash University, James Cook University and the Australian National University collaborated to investigate the role of these metabolic products of gut bacteria during pregnancy.
The "zero waste" trend could have a friend in the form of biosolids. Biosolids are the materials produced after domestic waste is treated in urban wastewater systems. In the past, most of this solid material was transferred to landfills. But, processes developed over the past few decades can create "exceptional quality" biosolids.
An aphrodisiac pheromone discovered in the semen of sea lampreys attracts ready-to-mate females, according to a study publishing July 9 in the open-access journal PLOS Biology by Anne M. Scott of Michigan State University, Zhe Zhang of Shanghai Ocean University, and colleagues.
CORVALLIS, Ore. - The most extensive and systematic insect monitoring program ever undertaken in North America shows that butterfly abundance in Ohio declined yearly by 2%, resulting in an overall 33% drop for the 21 years of the program.
While pilots rely on radio signals, advanced computations and tools to keep them on course during strong crosswinds, birds can naturally navigate these demanding conditions - and do so in environments with little visibility. To understand how they accomplish this feat, researchers in the lab of David Lentink, assistant professor of mechanical engineering at Stanford University, studied lovebirds flying in a crosswind tunnel which features customizable wind and light settings.
EAST LANSING, Mich. - Some people are drawn to cologne; others are attracted to perfume. When it comes to sea lampreys, however, spermine smells like love.
In new research led by Michigan State University and published in the current issue of PLoS Biology, spermine, an odorous compound found in male semen, proved to be a powerful aphrodisiac.
