Leuven researchers present technique to grow tissue implants for bone defects
Researchers from KU Leuven and University Hospitals Leuven have managed to engineer living implants in the lab by mimicking how bone tissue is created in an embryo. The technology paves the way for bone-regenerating tissue implants created on an industrial scale using 3D bioprinting. The researchers expect the first living implants to be available to patients in four years.

Immune cell health discovery could optimise cancer therapies
Scientists at UCL have discovered how immune cells, essential for tackling infections and cancers, are able to 'recycle' material within themselves in order to stay healthy and function, a breakthrough finding which could lead to more effective immunotherapies. In the study, published in Cell Reports , researchers investigated how 'autophagy' - the natural physiological process of 'self-eating' which allows intracellular components, such as mitochondria, to be degraded and replaced - takes place in liver-based T cells.

Health gap between rich and poor has widened
The health of the poorest people in Britain has declined since the mid-20th century, and is worse when compared to those born a century ago, suggests a new UCL-led study. The study, published in the BMJ Journal of Epidemiology and Community Health , compared health and income data from more than 200,000 working-age adults who were born between 1920 and 1970.

Earth's oldest known impact might have ended 'snowball Earth' ice age
Earth’s oldest known impact might have ended ’snowball Earth’ ice age
New evidence has confirmed Australia's Yarrabubba crater as the world's oldest preserved impact structure - but did it thaw Earth and end an ice age? The crater is regarded as one of Earth's oldest, but until now has lacked a precise age. Now, a new study has used geological dating to pin the impact to 2.229 billion years ago - a time that coincided with Earth's recovery from an ice age known as ‘ Snowball Earth ', where most of Earth's surface was covered with ice sheets between two and five kilometres thick.

’Love hormone’ improves attachment issues in people with autism
Oxytocin, often dubbed the 'love hormone', is known to promote social bonding. Researchers at KU Leuven have now discovered that administering oxytocin to adult men with autism makes them more open to close emotional bonds with others. The hormone has positive long-term effects as well. A team led by Professor Kaat Alaerts (KU Leuven) recruited 40 adult men with autism spectrum disorder to take part in their study. "In a first stage, we examined the amount of oxytocin produced by the participants themselves.

Putting a finger on the switch of chronic parasite infection
Putting a finger on the switch of chronic parasite infection
Researchers find master regulator needed for Toxoplasma gondii parasite to chronically infect host; promising step toward infection treatment, prevention. Toxoplasma gondii (T. gondii) is a parasite that chronically infects up to a quarter of the world's population, causing toxoplasmosis, a disease that can be dangerous, or even deadly, for the immunocompromised and for developing fetuses.

Festival fireworks celebrations’ health impact on vulnerable people - study
Fireworks associated with festival celebrations such as Australia Day, China's Lunar New Year and Fourth of July, in the USA, may have a significant impact on the health of vulnerable people - a new study reveals. Using fireworks during these celebrations generates anthropogenic source of air pollutants with significant impacts on local air quality, creating up to eight times the average of particulate matter (PM) concentration in the environment during and immediately after the event.

Mosquitoes are drawn to flowers as much as people - and now scientists know why
Mosquitoes are drawn to flowers as much as people - and now scientists know why
Without their keen sense of smell, mosquitoes wouldn't get very far. They rely on this sense to find a host to bite and spots to lay eggs. And without that sense of smell, mosquitoes could not locate their dominant source of food: nectar from flowers. "Nectar is an important source of food for all mosquitoes," said Jeffrey Riffell , a professor of biology at the University of Washington.

New housing design in England overwhelmingly ’mediocre’ or ’poor’
The design of new housing developments in England is overwhelmingly 'mediocre' or 'poor', with less-affluent communities the worst affected, according to a national audit conducted by UCL for CPRE, the countryside charity, and the Place Alliance. A housing design audit for England reveals that 75% of new housing development should not have gone ahead due to 'mediocre' or 'poor' design.

Small predators lose out from human land use
Predators, especially small invertebrates like spiders and ladybirds, are the most likely to be lost when natural habitats are converted to agricultural land or towns and cities, finds a new UCL-led study. The first of its kind, global study on the impacts of human land use on different groups of animals is published in the British Ecological Society journal Functional Ecology .

Emissions of potent greenhouse gas have grown, contradicting reports of huge reductions
Over the last two decades, scientists have been keeping a close eye on the atmospheric concentration of a hydrofluorocarbon (HFC) gas, known as HFC-23. This gas has very few industrial applications. However, levels have been soaring because it is vented to the atmosphere during the production of another chemical widely used in cooling systems in developing countries.

Reconstructing structure and function of a neuronal circuit
Reconstructing structure and function of a neuronal circuit
Reconstructing structure and function of a neuronal circuit The function of neuronal circuits is thought to be determined largely by specific connections between neurons. But this assumption has been difficult to test because the reconstruction of the synaptic connectivity of a neuronal circuit - its "wiring diagram" - is a major challenge.

Cardiac and visual degeneration arrested by a food supplement
Cardiac and visual degeneration arrested by a food supplement
UNIGE researchers have discovered a new gene that causes blindness and cardiomyopathy. They have also managed to halt the progression of eye disease and treat cardiac disease by administering a food supplement. Our genome consists of 20,000 genes, all of which may be capable of triggering disease. It is estimated that there are 7,000 unknown genes that cause recessive genetic diseases resulting from mutations in two copies of a gene that have been inherited from each parent.

"Green economy": an ambiguous concept that is on the way out
Concerns about climate change have given rise to a whole series of concepts that are widely used despite their lack of a concrete definition. EPFL researchers have taken a closer look at the "green economy" concept in particular to clarify exactly what it means. Today's consumers want a cleaner, greener society.

Arctic sea ice can’t ’bounce back’
Arctic sea ice cannot “quickly bounce back” once climate change causes it to melt, new research suggests. A team including scientists from Cardiff University used the shells of quahog clams, which can live for hundreds of years, and climate models to discover how Arctic sea ice has changed over the last 1,000 years.

Our biological clock plays crucial role in healing from surgery
Channels McGill University News and Events If you have just had knee, shoulder or hip surgery, you may want to take anti-inflammatories in the morning or at noon, but not at night. A McGill-led study shows, for the first time, that circadian clock genes are involved in healing from surgery. Indeed, the researchers demonstrated that anti-inflammatory medications are most effective in promoting post-operative healing and recovery when taken during the active periods of our biological clocks.

Cameras see around corners in real time with deep learning
Rice researchers, collaborators create system for fast imaging of hidden objects Imagine a camera that can see around corners. Researchers spent years figuring out how to use lasers to basically turn solid walls into mirrors. Now engineers from Rice University, Princeton University and Southern Methodist University have harnessed the power of a type of artificial intelligence known as deep learning to create a new laser-based system that captures detailed images of objects around corners in real time.

Uses physics to explain democratic elections
Uses physics to explain democratic elections
U.S. elections have become more "unstable," sometimes swinging in the opposite direction from the greater electorate's preferences. It may seem surprising, but theories and formulas derived from physics turn out to be useful tools for understanding the ways democratic elections work, including how these systems break down and how they could be improved.

Could reduce the risk of sudden cardiac death
New research has shown that by changing the time course of voltage change early when the heart cell contracts it is possible to both withhold a potentially lethal electrical disturbance and improve the strength of cardiac contraction in heart failure at the same time. The research led by the University of Bristol and funded by the Medical Research Council (MRC) is published today [20 January] in the Proceedings of the National Academy of Sciences (PNAS).

Confirms lingering mood benefit of psychedelics
People who had recently used psychedelics such as psilocybin report a sustained improvement in mood and feeling closer to others after the high has worn off, shows a new Yale study published the week of Jan. 20 in the journal Proceedings of the National Academy of Sciences. The results of a field study of more than 1,200 people attending multi-day arts and music festivals in the United States and United Kingdom confirm previous laboratory research indicating that psychedelic substances enhance feelings of social connectedness and improve mental well-being, the authors say.
