New guidelines explain how to monitor and treat hyperthyroid cats

HILLSBOROUGH, NJ (May 3, 2016) - Over the last 30+ years, veterinary professionals' understanding of clinical feline hyperthyroidism (FHT) has evolved tremendously. Initially FHT cats were referred to a specialist and now primary practitioners routinely manage these cases. The disease reportedly affects from 1.5-11.4% of cats around the world and is the most common endocrine disease of cats over 10 years of age in the US.

The intermediates in a chemical reaction photographed 'red-handed'

The intermediates in a chemical reaction photographed 'red-handed'

One of the long-standing goals being pursued by chemists has been to succeed in following and directly visualising how the structures of molecules change when they undergo complex chemical transformations. Reaction intermediates, which are highly unstable substances that form in different steps in a reaction before the products are obtained, are particularly difficult to identify and characterise owing to their short lifetimes.

Algae use their 'tails' to gallop and trot like quadrupeds

Algae use their 'tails' to gallop and trot like quadrupeds

Long before there were fish swimming in the oceans, tiny microorganisms were using long slender appendages called cilia and flagella to navigate their watery habitats. Now, new research reveals that species of single-celled algae coordinate their flagella to achieve a remarkable diversity of swimming gaits.

HIV infections drop, but US falls short of national goals

PHILADELPHIA--The number of new HIV infections and the transmission rate in the United States dropped by 11 and 17 percent, respectively, between 2010 and 2015, but fell short of the goals put forth by President Obama's U.S.

Turn up the heat to increase altitude tolerance

Altitude training is a popular method for athletes wanting to improve their physical performance. At high altitudes oxygen levels are blood cells. This enables an enhanced performance at lower altitudes because more oxygen can be delivered to the muscles.

Many companies now offer altitude training in specialist chambers (often referred to as normobaric training) as an alternative to lowered so our bodies compensate by increasing the number of red traveling to a high altitude country (hypobaric training), which is costly in terms of both time and money.

Estimates of cheetah numbers are 'guesswork', say researchers

Current estimates of the number of cheetahs in the wild are 'guesswork', say the authors of a new study which finds that the population in the cheetah stronghold of Maasai Mara, Kenya, is lower than previously thought.

In the early 1900s it was believed that around 100,000 cheetahs roamed the Earth. The most recent estimate by the International Union for Conservation of Nature (IUCN) puts the figure at 6,600 - mainly in eastern and southern Africa - amid fears that the fastest land mammal is racing to extinction.

Research on modern day animals reveals insights into extinct animals

Powerful head and neck retractions of vertebrate carcasses, including dinosaur fossils, have puzzled researchers as to whether they occurred just before an animal's death in agony, or after. Now experiments performed in the wild on large ostrich chick cadavers show that they occur post-mortem.

The experiments show that the timing of soft tissue decay is critical, and that muscle destruction or loss of tone must occur before ligament destruction. This would allow for the release of stored energy in the ligament and result in vertebral retraction.

Grape polyphenols help counter negative effects of high fat diet

FRESNO, CA - Grape polyphenols helped offset some of the adverse health consequences of consuming a high fat diet rich in saturated fat, according to two laboratory studies [1][2] conducted at the University of North Carolina Greensboro, and published recently in the Journal of Nutritional Biochemistry.

New research provides insights on seal species

Conservation and management efforts rely on clear definitions of populations, subspecies, and species. A new study uses digital imaging, state-of-the-art genetic analyses, archives of historical literature, and other methods to resolve the origin and whereabouts of a more than 200 year old grey seal specimen held in the collections of the Natural History Museum of Denmark, and to prove that this was the lost type specimen of the species. These and similar methods may be applied to identify, describe, and study existing, lost, and novel specimens.

Herbal remedies are an overlooked global health hazard

Millions of people around the world use herbal health remedies, following a tradition that began millennia ago. Many believe that herbs are safe because they have been used for many years, but researchers from Baylor College of Medicine and Stony Brook University are raising awareness that long-term use of herbal remedies is no guarantee of their safety. The invited commentary appears in EMBO reports.
