Scientists have developed a mouse model to study Zika virus transmitted sexually from males to females, as well as vertically from a pregnant female to her fetus. They are using the model to study how and when the virus is spread, including how the virus crosses the placenta, as well as to investigate potential treatments to block virus transmission.

Secrets of ancient Irish funeral practices revealed
New insights into the lifeways -- and death rites -- of the ancient people of Ireland are being provided through recent funerary studies.
The future of search engines
New efforts to combine artificial intelligence with crowdsourced annotators and information encoded in domain-specific resources have now been revealed by researchers. The work has the potential to improve general search engines, as well as ones like those for medical knowledge or non-English texts.
Cretaceous snails conceal themselves in monuments in Madrid
The fountains standing next to the Museo del Prado are built using a sedimentary rock full of gastropod shells from the time of the dinosaurs. These fossils have revealed the origin of the stone: forgotten quarries in Redueña, in the province of Madrid, where the building material for the Fountain of Apollo and the Palacio de las Cortes also came from.
Different sensory pathways engaged in feeling and responding to external temperature
Researchers have investigated different sensory neural pathways involved in thermoregulation by injecting toxins into parts of the brain involved in 'feeling' and responding to temperature changes in the environment. They found that, even upon disabling the pathway for such feeling, rats were able to avoid uncomfortably hot and cold floor plates, but that disabling part of the lateral parabrachial nucleus-mediated pathway led to the loss of this behavior and the loss of core body temperature regulation.
Arthritis drug could treat blood cancer patients, breakthrough finds
A drug used for arthritis could be used to treat blood cancer, scientists have found. Polycythemia vera, a type of blood cancer, affects 3,000 people a year. This breakthrough offers an affordable and effective treatment, say the investigators.
Current threats to our oceans revealed
A survey of tens of thousands of marine studies from the last decade reveals current threats to our marine environment. These include: the effects of climate change, marine plastic pollution, conservation, as well as social and economic impacts. It is hoped the method used to obtain this information, which has only just been made possible with advances in computational power, will enable the development of robust policies that ensure the future health of our seas.
