New function for potential tumor suppressor in brain development
The gene Cdkn1c could have been considered an open-and-shut case: Mice in which the gene is removed are larger and have bigger brains, so Cdkn1c should function to inhibit growth. This rationale has led to Cdkn1c being studied as a tumour suppressor gene. New research from the group of Simon Hippenmeyer, professor at the Institute of Science and Technology Austria (IST Austria), has now uncovered...
Stellar black holes: When David poses as Goliath
Stellar black holes form when massive stars end their life in a dramatic collapse. Observations have shown that stellar black holes typically have masses of about ten times that of the Sun, in accordance with the theory of stellar evolution. Recently, a Chinese team of astronomers claimed to have discovered a black hole as massive as 70 solar masses, which, if confirmed, would severely challenge...
Water governance: could less sometimes be more?
Researchers from UNIGE and UNIL analysed water governance in six European countries from 1750 onwards. They demonstrated that there has been an inflationary trend in the number of regulations, and that—far from improving the situation—this has led to serious malfunctions in the system.
New approach for controlling qubits via microwave pulses reduces error rates and increases efficiency
A functional quantum computer is one of the most intriguing promises of quantum technology. With significantly increased computing power, quantum computers will be able to solve tasks that conventional computers cannot handle, such as understanding and inventing new materials or pharmaceuticals as well as testing the limits of cryptographic techniques.
Water governance: Could less sometimes be more?

Does the never-ending introduction of new regulations of environmental resources have a positive effect? Researchers analyzed water governance regulations in six European countries from 1750 to 2006 and show that rules designed to improve resource management come into conflict in the long run, creating an equal number of positive and negative effects until the system falls apart. At this point,...

Deep learning, 3D technology to improve structure modeling, create better drugs
- ScienceDaily
- 20/1/10 16:10
Researchers have designed a novel approach to use deep learning to better understand how proteins interact in the body - paving the way to producing accurate structure models of protein interactions involved in various diseases and to design better drugs that specifically target protein interactions.
Global warming is the kindling that caused extensive wildfire
- ScienceDaily
- 20/1/10 16:10
Researchers identified Arctic Oscillation as the cause for the recent wildfires in Siberia. Their study forecasts wildfire activity in spring, helping to prevent carbon release and global warming.
A stripped helium star solves the massive black hole mystery
- ScienceDaily
- 20/1/10 16:10
Recently, a Chinese team of astronomers claimed to have discovered a black hole as massive as 70 solar masses, which, if confirmed, would severely challenge the current view of stellar evolution. Among those to take a closer look at the object were astronomers from the Universities of Erlangen-Nürnberg and Potsdam. They discovered that it may not necessarily be a black hole at all, but possibly a...
Unused stockpiles of nuclear waste could be more useful than we might think
- ScienceDaily
- 20/1/10 16:10
Chemists have found a new use for the waste product of nuclear power -- transforming an unused stockpile into a versatile compound which could be used to create valuable commodity chemicals as well as new energy sources.
Experiment on beta-decay sheds light on fate of intermediate-mass stars
- ScienceDaily
- 20/1/10 16:10
A group of scientists succeeded to experimentally determine characteristics of nuclear processes in matter ten million times denser and 25 times hotter than the center of our sun. A result of the measurement is that intermediate-mass stars are very likely to explode, and not, as assumed until now, collapse.
Newest Canadian astronauts graduate, ready to fly to the moon
Canada’s two newest astronauts, Jenni Sidey-Gibbons and Joshua Kutryk, graduated today from NASA’s astronaut basic training, making them officially eligible for space flight — and to possibly become the first Canadians on the...
New function for potential tumor suppressor in brain development

- 20/1/10 16:08
New research has now uncovered a novel, opposite role for Cdkn1c. When Cdkn1c is removed only in certain cells of the brain, these cells die, arguing for a new growth promoting role of Cdkn1c.

Molecular 'doormen' open the way to potential obesity treatment
- ScienceDaily
- 20/1/10 13:37
Fat cells are filled with droplets coated by molecules that act like hotel doormen: These 'doormen' control cellular access for nutrients as well as for the exit of energy-supplying molecules called lipids. In healthy individuals, outgoing and incoming traffic in fat cells is finely balanced, supplying energy while preventing excessive spread of undesirable fat in the belly.
