Yellow fever killing thousands of monkeys in Brazil
In a vulnerable forest in southeastern Brazil, where the air was once thick with the guttural chatter of brown howler monkeys, there now exists silence. Yellow fever, a virus carried by mosquitoes and endemic to Africa and South America, has robbed the private, federally-protected reserve of its brown howlers in an unprecedented wave of death that has swept through the region since late 2016, killing thousands of monkeys.

New study shakes the roots of the dinosaur family tree
More than a century of theory about the evolutionary history of dinosaurs has been turned on its head following the publication of new research.

Weight-bearing exercises promote bone formation in men
Osteoporosis affects more than 200 million people worldwide and is a serious public health concern, according to research. Now, newly published work is the first in men to show that long-term, weight-bearing exercises decrease sclerostin, a protein made in the bone, and increase IGF-1, a hormone associated with bone growth. These changes promote bone formation, increasing bone density.

Upper part of Earth’s magnetic field reveals details of a dramatic past
Satellites have been mapping the upper part of the Earth magnetic field by collecting data for three years and found some amazing features about the Earth’s crust. The result is the release of highest resolution map of this field seen from space to date. This ‘lithospheric magnetic field’ is very weak and therefore difficult to detect and map from space. But with the Swarm satellites it has been possible.

New cell membrane fusion model challenges dogma
Membrane fusion lies at the heart of many cell functions—from the secretion of antibodies to the release of neurotransmitters. For more than two decades, one view of the process by which membrane fusion occurs has been accepted as dogma; now recent studies indicate that fusion is more complex. These discoveries are being regarded by at least one leading cell biologist as “textbook changing” and could alter how we develop drugs that affect membrane fusion activities.

Egyptian ritual images from the Neolithic period
Egyptologists have discovered rock art from the 4th millennium BC during an excavation at a necropolis near Aswan in Egypt. The paintings were engraved into the rock in the form of small dots and depict hunting scenes like those found in shamanic depictions. They may represent a link between the Neolithic period and Ancient Egyptian culture. The discovery earned the scientists the award for one of the current ten most important archeological discoveries in Egypt from the Minister of Antiquities in Cairo.

Salmon with side effects: Aquacultures are polluting Chile's rivers with a cocktail of dissolved organic substances
Tasty, versatile, and rich in essential omega-3 fatty acids: salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms which can pollute rivers, lakes and oceans. Just how big is the problem? Scientists are working to answer this question by examining the dissolved organic compounds which enter Chile’s rivers from salmon farms. They warn that these substances are placing huge strain on ecosystems and are changing entire biological communities.

Caught on camera: Chemical reactions 'filmed' at the single-molecule level
Scientists have succeeded in ‘filming’ inter-molecular chemical reactions – using the electron beam of a transmission electron microscope (TEM) as a stop-frame imaging tool. They have also discovered that the electron beam can be simultaneously tuned to stimulate specific chemical reactions by using it as a source of energy as well as an imaging tool.

New rare muscle disorder discovered
A new rare muscle disorder has been identified by researchers. This hereditary disease is caused by a defect in the BICD2 gene that manifests itself in altered cellular transport processes in skeletal muscle cells. Patients suffer from muscle weakness in the legs, an unsteady gait and permanent risk of stumbling. BICD2 had been known as a disease trigger, but only for disorders originating in the nervous system. A BICD2 syndrome that manifests itself in altered skeletal muscles had never before been described.

New Hope for the Saiga Antelope?
The Saiga Antelope, which is currently threatened with extinction, used to be much more flexible in its habitat and food choices in the past than previously assumed, scientists have discovered. Based on carbon and nitrogen isotopes in the collagen from the antelopes’ bones, the scientists compared the diets of fossil versus modern-day Saiga. In their study, they reached the conclusion that today’s populations are not obligatorily bound to their current habitat. This insight offers new hope for this endangered species.
