Sustainable agriculture is building peace in Colombia

In areas of Colombia once controlled by guerillas, conflicts over land continue and deforestation has risen considerably. But it’s in these same areas that researchers have found that farmers implementing sustainable land use systems, like agroforestry driven by cocoa (one of the key ingredients of chocolate), has contributed to reducing conflicts. Deforestation and Conflict In 2016, the government of Colombia signed a peace treaty with the guerilla group Revolutionary Armed Forces of Colombia (FARC, for its initials in Spanish) and in the following years, forested areas formerly controlled by the FARC saw an influx of other illegal actors, contributing ...

Australian nanomedicine research a ‘milestone’ in the treatment of childhood cancer

Australian nanomedicine researchers have come up with a new approach to solving a decades-old clinical problem: getting treatment drugs to act selectively on cancer cells in the body. Published this week in the high-impact journal Science Translational Medicine, the research paves the way to safer and more effective treatment options for children with aggressive blood cancers, and potentially other types of cancer as well. Chemotherapy is the mainstay of treatment for leukaemia, the most common blood cancer in children. However, while chemotherapy can be very effective for certain types of leukaemia, ...

Scales or feathers? It all comes down to a few genes

Scales, spines, feathers and hair are examples of vertebrate skin appendages, which constitute a remarkably diverse group of micro-organs. Despite their natural multitude of forms, these appendages share early developmental processes at the embryonic stage. Two researchers from the University of Geneva (UNIGE) have discovered how to permanently transform the scales that normally cover the feet of chickens into feathers, by specificially modifying the expression of certain genes. These results, published in the journal Science Advances, open new perspectives for studying mechanisms that have enabled radical evolutionary ...

New study explains how a common virus can cause multiple sclerosis

Researchers at Karolinska Institutet in Sweden have found further evidence for how the Epstein-Barr virus can trigger multiple sclerosis or drive disease progression. A study published in Science Advances shows that some individuals have antibodies against the virus that mistakenly attack a protein in the brain and spinal cord. The Epstein-Barr virus (EBV) infects most people early in life and then remains in the body, usually without causing symptoms. The link between EBV and the neurological disease multiple sclerosis (MS) was discovered many years ago and has puzzled ...

Liver cells control our biological clock

Organisms rely on a biological clock known as the ‘circadian’ clock to regulate their activity according to the time of day. A central clock, constituted by a group of brain cells — the suprachiasmatic nuclei, or SCN — synchronises the circadian clocks present in all body’s organs, called ‘peripheral’ clocks. Until now, synchronisation of the circadian cycle in mammals was thought to be a one-way mechanism in which the suprachiasmatic nuclei alone synchronized the peripheral ...

Adult friendships can triumph over childhood trauma, even in baboons

DURHAM, N.C. -- Decades of research show that experiencing traumatic things as a child -- such as having an alcoholic parent or growing up in a tumultuous home -- puts you at risk for poorer health and survival later in life. But mounting evidence suggests that forging strong social relationships can help mitigate these effects. And not just for people, but for our primate cousins, too. Drawing on 36 years of data, a new study of nearly 200 baboons in southern Kenya finds that adversity early in life can take years off their lifespan, but strong social bonds with other baboons in adulthood can help ...

CCNY researchers use structured light on a chip in another photonics breakthrough

In everyday life we experience light in one of its simplest forms – optical rays or beams. However, light can exist in much more exotic forms. Thus, even beams can be shaped to take the form of spirals; so-called vortex beams, endowed with unusual properties. Such beams can make dust particles to spin, just like they indeed move along some intangible spirals. Light modes with such added structure are called “structured,” and even more exotic forms of structured light can be attained in artificial optical materials – metamaterials, where ...

Higher blood sugar linked to faster loss of brain power in stroke survivors

Surviving a stroke can bring many long-term effects – including a much higher risk of dementia. But a study suggests that blood sugar may play a key role in that risk. Loss of general thinking ability happened much faster in stroke survivors who had high blood glucose in the years after their health crisis, even after accounting for other things that might affect their brainpower, according to a study published in JAMA Network Open. Those whose blood pressures or cholesterol were high after their stroke did not lose points on tests of thinking ability, ...

A new understanding of human origins in Africa

There is broad agreement that Homo sapiens originated in Africa. But there remain many uncertainties and competing theories about where, when, and how. In a paper published today in Nature, an international research team led by McGill University and the University of California-Davis suggest that, based on contemporary genomic evidence from across the continent, there were humans living in different regions of Africa, migrating from one region to another and mixing with one another over a period of hundreds of thousands of years. This view runs counter to some of the dominant theories about human origins in ...

Newcomers may change ecosystem functions – or not

In a study tracking climate-induced changes in the distribution of animals and their effects on ecosystem functions, North Carolina State University researchers show that resident species can continue managing some important ecological processes despite the arrival of newcomers that are similar to them, but resident species’ role in ecosystem functioning changes when the newcomers are more different. The findings could lead to predictive tools for understanding what might happen as climate change forces new species into communities, such as the movement of species from lower to higher latitudes or elevations. “Species ...
