Viennese Scientists develop promising new type of polymers
S-PPV polymers are suitable for use in a wide range of applications, from solar cells through to medicine but, until recently, they were almost impossible to produce. Now, a new synthetic method has been patented. Organic polymers can nowadays be found in solar cells, sensors, LEDs and in many other technical applications.

XMM-Newton captures final cries of star shredded by black hole
Astronomers using ESA's XMM-Newton space observatory have studied a black hole devouring a star and discovered an exceptionally bright and stable signal that allowed them to determine the black hole's spin rate. Black holes are thought to lurk at the centre of all massive galaxies throughout the Universe, and are inextricably tied to the properties of their host galaxies.

Census data could be used to improve city neighbourhoods
A new analysis of the 2011 census has revealed that social differences among city populations significantly influence how neighbourhoods take shape. Researchers hope that their insights could help councils to make better planning decisions. Dr Thilo Gross and Dr Edmund Barter in the Department of Engineering Mathematics at the University of Bristol, used a new algorithm to gain insight into city neighbourhood characteristics, starting with Bristol.

Canada’s CHIME telescope detects second repeating fast radio burst
A Canadian-led team of scientists has found the second repeating fast radio burst (FRB) ever recorded. FRBs are short bursts of radio waves coming from far outside our Milky Way galaxy. Scientists believe FRBs emanate from powerful astrophysical phenomena billions of light years away.

McGill University helps to inform understanding of cancer risk
McGill University has helped develop a global resource that includes data on thousands of inherited variants in the BRCA1 and BRCA2 genes. The BRCA Exchange was created through the BRCA Challenge, a long-term demonstration project initiated by the Global Alliance for Genomics and Health (GA4GH) to enhance sharing of BRCA1/BRCA2 data.

Achieving goals in the lab and on the pitch
Senior Anthony Badea, a physics major and varsity soccer player, investigates the beginnings of the universe. Anthony Badea got hooked on physics during his senior of high school in Irvine, California. He used to fall asleep watching interviews and speeches by public figures in science like astrophysicist Neil deGrasse Tyson and string theorist Michio Kaku.

Citizen scientists help discover new exoplanet in ’habitable zone’
A new planet roughly twice the size of Earth has been discovered located within the "habitable zone"-the range of distances from a star where liquid water may exist on the planet's surface. A research team that included a UChicago graduate student confirmed the finding after volunteer citizens flagged a crucial piece of evidence in data from NASA's Kepler spacecraft.

Rare metals from e-waste
Rare metals from e-waste
This year, beautifully wrapped laptops, mobile phones or even new TV sets lay under numerous Christmas trees. They are enthusiastically put into use - and the old electronic devices are disposed of. The e-waste contains resources such as neodymium, indium and gold. What happens to the valuable materials' And how much rare metal is contained in mobile phones, computers and monitors that are still in use today? Empa researchers have investigated these questions.

Imperial experts create robot helper to understand and respond to human movement
Researchers at Imperial have created a new robot controller using game theory, allowing the robot to learn when to assist a human. The past decade has seen robots work increasingly with humans - for example in manufacturing, assistive devices for physically impaired individuals, and in surgery. However, robots cannot currently react in a personalised way to individual users, which limits their usefulness to humans.

A century and half of reconstructed ocean warming offers clues for the future
Due to a scarcity of data, most global estimates of ocean warming start only in the 1950s. However, a team of scientists at the University of Oxford has now succeeded in reconstructing ocean temperature change from 1871 to 2017. Over the past century, increased greenhouse gas emissions have given rise to an excess of energy in the Earth system.

Longer siesta on bright days
Longer siesta on bright days
Insects and mammals have special sensors for different light intensities. These sensors selectively influence the circadian clocks and thereby control daily activity patterns. Increasing sunlight intensity extends the sleep duration and results in a longer midday siesta which delays the resumption of activity to the evening.

Producing more solar power in wintertime thanks to snow
Installing photovoltaic panels in high mountains could significantly reduce the power deficit experienced by this renewable energy in winter, according to a joint study by the WSL Institute for Snow and Avalanche Research SLF and EPFL. The Swiss Energy Strategy 2050 reflects the decision to abandon nuclear power in the medium term.
