Whooping cough: scientists describe the bacteria’s mechanisms to survive

CONICET researchers found how this microorganism manages to evade the immune system and remain in the body

Whooping cough, caused by Bordetella pertussis, is one important cause of child morbidiy and mortality. According to the World Health Organization (WHO), it is estimated that there are around 50 million cases annually and 300 deaths.

Recent connection between north and south america reaffirmed

Aaron O’Dea, staff scientist at the Smithsonian Tropical Research Institute (STRI), and colleagues writing in 'Science Advances' firmly set the date at 2.8 million years ago

Long ago, one great ocean flowed between North and South America. When the narrow Isthmus of Panama joined the continents about 3 million years ago, it also separated the Atlantic from the Pacific Ocean. If this took place millions of years earlier, as recently asserted by some, the implications for both land and sea life would be revolutionary. Aaron O’Dea, staff scientist at the Smithsonian Tropical Research Institute (STRI), and colleagues writing in Science Advances firmly set the date at 2.8 million years ago.

The european project CITYCoP analyzes smart solutions for citizen safety

Its Mid-term Conference, will be an opportunity to learn and discuss about the community policing application

During this two day conference, the aims of the CITYCoP project will be presented and explored: the development of a community policing application for citizens and law enforcement of four European cities. Experts from various backgrounds will participate in the discussion and share their expertise in fields that include application development, municipality management, law enforcement in cities, building trust in community policing, citizen empowerment studies and a study on feelings of safety and security.

Genetic discovery would explain aggravating of refractory epilepsy

Loss or duplication of chromosomes in patients with epilepsy was discovered by a group of a Universidad Nacional de Colombia (UNal) researchers offers new clues to understand the disease

With these findings they consider that close to 15% of the patients with refractory epilepsy may have losses or gains of genetic material which will enable explaining its appearance or aggravating of the disease.

Vaccines protect monkeys against Zika

US trials prove efficacy of three formulations developed by team including São Paulo-based scientists affiliated with FAPESP-funded Zika Research Network

Trials recently completed in the United States have shown that three different vaccines provide effective and safe protection against Zika virus in rhesus monkeys.Two of the formulations, a vaccine based on an inactivated Zika virus and a DNA vaccine using two Zika genes, had already proved effective in mice, according to a report by Brazilian and US researchers published in Nature in late June (see Pesquisa FAPESP no. 245 for an account in Portuguese).

Neanderthal child tooth and parietal fragment discovered at Teixoneres Cave (Barcelona, Spain)

Ruth Blasco, researcher at the CENIEH, is co-leader of the excavation project "Teixoneres Cave", one of the Middle Palaeolithic sites in the Iberian Peninsula with new Neanderthal fossils

It is not common to find human remains in a Pleistocene archaeological site; nevertheless, they are very significant and can be used in numerous research fields. The analysis of the characters of each fossil gives us valuable information in order to understand not only the variability of a species, but also its diet type or its development patterns.

After the Age of Dinosaurs Came the Age of Ant Farmers

A group of South American ants has farmed fungi since shortly after the dinosaurs died out, according to an international research team including Smithsonian scientists

A group of South American ants has farmed fungi since shortly after the dinosaurs died out, according to an international research team including Smithsonian scientists. The genes of the ant farmers and their fungal crops reveal a surprisingly ancient history of mutual adaptations. This evolutionary give-and-take has led to some species—the leafcutter ants—developing industrial-scale farming that surpasses human agriculture in its efficiency.

Growing evidence that a peridomestic mosquito also transmits Zika virus

Scientists find viral load in saliva of 'Culex quinquefasciatus' to be similar to that in 'Aedes aegypti'

The mosquito Aedes aegypti has been considered the main vector of Zika virus, estimated to have infected 49,000 people by June 2016, although 139,000 cases were notified in this period. Zika is also widely considered as the cause of microcephaly in 1,600 babies born in 582 Brazilian cities.

ALMA Achieved Highest Polarimetric Sensitivity

Polarimetry is an important method to investigate magnetic fields in the Universe

Researchers have confirmed ALMA’s unprecedented capability for polarimetry in millimeter/submillimeter wavebands. Polarimetry is an important method to investigate magnetic fields in the Universe and astronomers are eager to use ALMA for unveiling magnetic mysteries, such as the launching mechanism of high energy jets from supermassive black holes.

New Guidance System with 3D sounds for the visually impaired

The application is designed to be installed in a mobile phone and uses satellite navigation and augmented acoustic reality to indicate to the user the correct path that is clear of obstacles

The visually impaired will be able to use a new system of sensorial guidance that uses 3D sounds. The system was developed by Geko NAVSAT, a company that receives assistance from the Business Incubator at the Universidad Carlos III de Madrid (UC3M) Science Park. The application is designed to be installed in a mobile phone and uses satellite navigation and augmented acoustic reality to indicate to the user the correct path that is clear of obstacles.

A Bioarchaeologist Reads History from Bones

Nicole Smith-Guzmán holds up a small lower jawbone and says it belonged to a seven-year old child who grew up on a sugary, corn-based diet

Nicole Smith-Guzmán holds up a small lower jawbone and says it belonged to a seven-year old child who grew up on a sugary, corn-based diet. Although the child died over 1,500 years ago, she can determine its age to within six months based on the number and size of milk versus permanent teeth. She points out several signs of dental disease—a tooth cavity, an abscess in the jawbone, a gap from a fallen milk tooth with the bone healed over before the permanent tooth could grow out. On another person’s jaw, impacted teeth suggest that the jawbone never grew to its full potential because it only chewed on soft, mushy food. On yet another set of teeth, she points out ancient tartar, which may hold plant remains and even traces of mouth bacteria.

ALMA Discovers a Rotating Ring of Complex Organic Molecules

This observation definitively shows that organic materials formed in interstellar space are brought into the planet-forming region

Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a rotating ring containing large organic molecules around a protostar. This observation definitively shows that organic materials formed in interstellar space are brought into the planet-forming region. Researchers also found that the molecular species brought into the planet-forming region vary from one protostar to another. Chemical composition is a new way to answer the long-standing question of whether or not the Solar System is a typical example of a planetary system.

Using a reverse paint-by-numbers approach, scientists have located another gene that controls the brilliant patterning of Heliconius butterfly wings

Using a reverse paint-by-numbers approach, scientists have located another gene that controls the brilliant patterning of Heliconius butterfly wings. Led by former Smithsonian Tropical Research Institute (STRI) fellow Nicola Nadeau, the researchers identified variations in the gene that correspond to wing color and pattern variation in three different Heliconius species. Published in Nature, June 2016, the discovery puts scientists a step closer to unlocking the code responsible for diversity and evolution in butterflies and moths.
