Morris Animal Foundation, a leader in advancing animal health, has awarded nearly $1 million in large animal health research grants, supporting 14 projects. The studies will help veterinary scientists improve the well-being of horses…

URBANA, Ill. - For many livestock species, artificial insemination (AI) is standard. But it can be tricky to achieve success the first time, thanks to variability in ovulation timing across the herd. Sperm remains viable for a day or…

Why does exercise training make you more fit? It's well established that exercising enhances insulin sensitivity and improves our metabolism that, in turn, increases exercise performance. But the biological mechanisms underlying this…

Some microorganisms, the so-called methanotrophs, make a living by oxidizing methane (CH4) to carbon dioxide (CO2). Ammonia (NH3) is structurally very similar to methane, thus methanotrophs also co-metabolize ammonia and produce…

SIDT1 polymorphism affects the antiviral effects of honeysuckle decoction Previously, Chen-Yu Zhang's group have identified SID1 transmembrane family member 1 (SIDT1) as a critical membrane protein mediating dietary miRNAs absorption,…

UNIGE Scientists demonstrate that warmth exposure improves bone strength, and decipher the role of gut microbiota in this phenomenon. This gives rise to innovative perspectives in the treatment of osteoporosis. Osteoporosis, a bone disease…
