In Wild Chimpanzees, Human Respiratory Viruses Continue To Spread

Less than two years after the first report of wild chimpanzee in Uganda dying as a result of a "common cold" virus, a new study has identified two other respiratory viruses of human origin in chimpanzee groups in the same forest. Writing this week in the journal  Emerging Microbes and Infections , a team led by Tony Goldberg, an expert on emerging pathogens in animals, describes two simultaneous outbreaks of respiratory illness in chimpanzees in the wild, one of which was lethal. Goldberg is also associate director for research at UW-Madison's Global Health Institute.

Non-communicable Diseases As Major Threat: WHO Identifies

The World Health Organization (WHO) has listed out 10 major threats to the health of majority of the global population in 2019. The problems range from communicable diseases such as measles and diphtheria that are vaccine preventable, to non communicable diseases such as heart disease, obesity, drug resistant microbes etc. This year 2019 is slated to be the start of the five-year plan from the organization to tackle these threats.

On The WHO's Agenda: A Global Influenza Pandemic Is On High

Another influenza pandemic is on the third spot of the list of 10 health threats collated by the World Health Organization for 2019. The WHO has come up with a list to address these 10 threats. This year 2019 is slated to be the start of the five-year plan from the organization to tackle these threats. The 5 year strategic plan is called the 13th General Programme of Work or the 13th GPW. IT plants to achieve these targets on the basis of the devised Sustainable Development goals (SDG).

Zika Vaccination: Responses By CD4+ T Cells

Immune cells called CD4+ T cells could be important mediators of protection against the Zika virus, according to a study published in the open-access journal PLOS Pathogens by Sujan Shresta of the La Jolla Institute for Allergy and Immunology, and colleagues. The findings support vaccine strategies that induce a protective CD4+ T cell response to the Zika virus.

The First Stable Simulations Of DNA Crystals: Scientists Achieved

A new breakthrough enables the study of the role of each molecular component in the stability and conformation of DNA crystals. Since the birth of structural biology, X-ray crystallography has been the most widely used technique to determine the three-dimensional structure of biomolecules — the chemical compounds found in living organisms.

Progressive Cone And Cone-Rod Dystrophies

Progressive cone and cone-rod dystrophies are a clinically and genetically heterogeneous group of inherited retinal diseases characterised by cone photoreceptor degeneration, which may be followed by subsequent rod photoreceptor loss. These disorders typically present with progressive loss of central vision, colour vision disturbance and photophobia. 

Anxiety-related Behavior By Common Food Additives

Food additives known as dietary emulsifiers, commonly found in processed foods to improve texture and extend shelf life, may adversely affect anxiety-related and social behaviors in mice, Georgia State researchers have found. The scientists also observed sex differences in the mice's behavioral patterns, suggesting that emulsifiers affect the brain via distinct mechanisms in males and females.

Mystery Behind How Proteins Interact With Cell Membrane

Trillions of cells all different shapes and sizes form a human body's structure. Surrounding each cell is a membrane, jointly acting as hostess and security welcoming certain information into the cell while making sure its components don't spill out into the body's void. Much is known about how the individual pieces of a cell work, but a significant understanding of how proteins interact with the cell membrane has remained a mystery until now, following a recent study at the University of Missouri.

Brain Condition Related To long-Term Spaceflights

More people today are poised to explore space than ever before; those who will experience the effects of microgravity on the human body. Recognizing the need for more data related to those effects, Medical University of South Carolina (MUSC) neuroradiologist Donna Roberts, MD, and co-author Lonnie G. Petersen, Ph.D., "The Study of Hydrocephalus Associated With Long-term Spaceflight (HALS) Provides New Insights into Cerebrospinal Fluid Flow.
