Antimalarial drugs could support existing cancer treatments in two-pronged attack
Antimalarial drugs chloroquine and hydroxychloroquine could make tumour cells more sensitive to cancer treatment.

Ludwig researchers unravel novel mechanism by which tumors grow resistant to radiotherapy
A Ludwig Cancer Research study has uncovered a key mechanism by which tumors develop resistance to radiation therapy and shown how such resistance might be overcome with drugs that are currently under development.

Comparison of primate brains hints at what makes us human
A detailed comparative analysis of human, chimpanzee and macaque brains reveals elements that make the human brain unique, including cortical circuits underlying production of the neurotransmitter dopamine.

Physicists develop faster way to make Bose-Einstein condensates
MIT physicists have invented a new technique to cool atoms into condensates, which is faster than the conventional method and conserves a large fraction of the original atoms.

Serious mortuary errors could be reduced by applying common patient safety protocols
New research investigating serious incidents occurring in the management of patient remains after their death concludes that safe mortuary care may be improved by applying lessons learned from existing patient safety work.

Push to twist: Achieving the classically impossible in human-made material
Researchers have designed a metamaterial that can twist to the right or the left in response to a straight, solid push.

Small but distinct differences among species mark evolution of human brain
The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity.

New batteries with better performance and improved safety
Currently the most important technology for batteries is the lithium-ion battery technology: but the technology is expensive and contains a flammable liquid.

Ocean floor mud reveals secrets of past European climate
Samples of sediment taken from the ocean floor of the North Atlantic Ocean have given researchers an unprecedented insight into the reasons why Europe's climate has changed over the past 3,000 years.

Scientists find key to regenerating blood vessels
Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a signaling pathway that is essential for angiogenesis, the growth of new blood vessels from pre-existing vessels.

Galapagos study finds that new species can develop in as little as 2 generations
A study of Darwin's finches, which live on the Galapagos Islands in the Pacific Ocean, has revealed direct genetic evidence that new species can arise in just two generations.

How badly do you want something? Babies can tell
Babies as young as 10 months can assess how much someone values a particular goal by observing how hard they are willing to work to achieve it, according to a new study from MIT and Harvard.

The world needs to rethink the value of water
Research led by Oxford University, published today in Science, highlights the accelerating pressure on measuring, monitoring and managing water locally and globally.

Infants understand that more desirable rewards require more effort
Infants who observe someone putting more effort into attaining a goal attribute more value to it, a new study finds.

World's smallest tape recorder is built from microbes
Through a few clever molecular hacks, researchers at Columbia University Medical Center have converted a natural bacterial immune system into a microscopic data recorder, laying the groundwork for a new class of technologies that use bacterial cells for everything from disease diagnosis to environmental monitoring.

Helpers at the nest may allow mother birds to lay smaller eggs
Cooperatively breeding birds and fish may have evolved the adaptive ability to reduce the size of their eggs when helpers are available to lighten the parental load, a new study suggests.

Research reveals China's reversing emission flows
The flow of China's carbon emissions has reversed according to new research led by scientists at the University of East Anglia (UEA).

Radiographs of Dolly's skeleton show no signs of abnormal osteoarthritis
Original concerns that cloning caused early-onset osteoarthritis in Dolly the sheep are unfounded, say experts at the University of Nottingham and the University of Glasgow.

Tumor-associated bacteria hitches a ride to metastatic sites
The same bacteria present in primary tumors of patients with colorectal cancer are also present in liver metastases, a new study finds.

Meadows beat out shrubs when it comes to storing carbon
While the world focuses on controlling global warming caused by CO2 emissions from fossil fuels, less attention has been paid to the capacity of vegetation and soils to take up and store carbon.

Climate change could increase volcano eruptions
Shrinking glacier cover could lead to increased volcanic activity in Iceland, warn scientists.

Effects of ethnocentrism on consumers
Aitor Calvo-Turrientes, winner of the prize for End-of-Degree Project in Sustainability in 2015 awarded by the Faculty of Economics and Business of the UPV/EHU-University of the Basque Country in Vitoria-Gasteiz, is the author of the paper 'The valuation and purchase of food products that combine local, regional and traditional features: The influence of consumer ethnocentrism,' published recently by the prestigious journal Food Quality and Preference.

When friends become objects
Why do people use social media? Striving to answer this question, social psychologists at Ruhr-Universit├Ąt Bochum have conducted a survey with more than 500 Facebook users with regard to their personality structure and the way they use the platform.

Neurobiology: The chemistry of memory
Learning requires the chemical adaptation of individual synapses. Researchers have now revealed the impact of an RNA-binding protein that is intimately involved in this process on learning and memory formation and learning processes.

Eurac Research submits a report on environmental crimes in the Carpathians to European Parliament
The study out of the Bolzano-based research center, commissioned by World Wide Fund for Nature and the United Nations Environmental Program, captures the current situation and proposes recommendations.

Light facilitates n-doping of organic semiconductors
Doping organic semiconductors with negative charges is difficult. Now a German-American research team has applied a trick: as a first step, they transformed the fragile charge-donor molecules into dimers that are far more stable.

'Lost' 99 percent of ocean microplastics to be identified with dye?
The smallest microplastics in our oceans -- which go largely undetected and are potentially harmful -- could be more effectively identified using an innovative and inexpensive new method, developed by researchers at the University of Warwick.

Harvey is one of the top 10 most costly natural disasters of all-time
Hurricane Harvey, which has hit the US state of Texas with devastating damage, is in third place among the world's most expensive storm disasters.

The piezoelectric effect of lysozyme was experimentally proved
A group of researchers from the University of Limerick and Ural Federal University received direct evidence of the piezoelectric effect of lysozyme in monoclinic and tetragonal aggregate films of lysozyme.

Hormone therapy in the menopause transition does not increase risk of stroke
Postmenopausal hormone therapy is not associated with increased risk of stroke, provided that it is started early, according to a report from Karolinska Institutet in Sweden published in the journal PLOS Medicine.
