Unlocking efficient light-energy conversion with stable coordination nanosheets
- ScienceDaily
- 21/7/15 18:45
Two-dimensional 'nanosheets' made of bonds between metal atoms and organic molecules are attractive candidates for photoelectric conversion, but get corroded easily. In a new study, scientists present a new nanosheet design using iron and benzene hexathiol that exhibits record stability to air exposure for 60 days, signaling the commercial optoelectronic applications of these 2D materials in the...

Researchers set out to develop technology capable of localizing and imaging blood clots in deep veins. Turns out their work may not only identify blood clots, but it may also be able to treat them.
What does the sleeping brain think about?

- 21/7/15 18:45
Using an artificial intelligence approach capable of decoding brain activity during sleep, scientists were able to glimpse what we think about when we are asleep. By combining fMRI and EEG, they provide unprecedented evidence that the work of sorting out the thousands of pieces of information processed during the day takes place during deep sleep. Indeed, the brain can evaluate all of these...
Blue Origin: Teenager to fly into space with Jeff Bezos
Oliver Daemen, 18, will become the youngest person to fly to space with the Blue Origin venture.

Blue Origin says will fly 18-year-old to space on July 20
Blue Origin said Thursday an 18-year-old paying customer will fly to space on board the company's maiden crewed spaceflight on July 20, becoming the youngest ever astronaut.
A new avenue for fighting drug-resistant bacteria
A small regulatory RNA found in many problematic bacteria, including Escherichia coli, appears to be responsible for managing the response of these bacteria to environmental stresses. Professor Charles Dozois from Institut national de la recherche scientifique (INRS) and doctoral student Hicham Bessaiah see a promising avenue for more effective treatment of antibiotic-resistant bacteria. Their...
'It's crazy': Germany's Mayen town hit by flash floods
Residents of the German town of Mayen stood stunned and helpless on Thursday as the worst flooding in years submerged their homes and sent torrents flowing down the streets.
Examining potential variance in academic research
New research seeks to understand what drives decisions in data analyses and the process through which academics test a hypothesis by comparing the analyses of different researchers who tested the same hypotheses on the same dataset. Analysts reported radically different analyses and dispersed empirical outcomes, including, in some cases, significant effects in opposite directions from each other....
New study measures how nitrogen is managed in agriculture around the world
The business world is familiar with Peter Drucker's assertion that "If you can't measure it, you can't improve it." For the sake of environmental sustainability and food security, there is an urgent need for agriculture to improve its use of nitrogen fertilizers, but can we properly measure it?
Scientists create rechargeable swimming microrobots using oil and water
A new study, published today in Nature Physics, has shown that it is possible to create tiny, self-powered swimming robots from three simple ingredients.
Newly discovered role for CTP in ensuring faithful cell division in bacteria
To grow and multiply efficiently, bacteria must coordinate cell division with chromosome segregation. Crucial to this process in the bacterium Bacillus subtilis (commonly found in soil and the guts of humans and ruminants) is a protein called Nucleoid Occlusion Factor or Noc.
Nitrogen-producing process of anammox bacterium finally uncovered
After years of research, the molecular structure of the enzyme responsible for a large part of the global nitrate and nitrogen production by bacteria has finally been uncovered. The anammox bacterium and other bacteria use this enzyme to convert toxic nitrite into nitrate. Now that the working of the enzyme has become clear, new possibilities have opened for the improved deployment of the anammox...
Visibly transparent radiative cooler under direct sunlight
Since the Paris Climate Agreement took effect in 2016, 121 countries have pledged to become carbon neutral by 2050 as the world tries to reduce its fuel consumption. The Korean government unveiled its 2050 Carbon Neutral Strategy on December 7, 2020 and declared Carbon Zero, making transition to new and renewable energy a topic of conversation. Recently, a joint research team from POSTECH and...
Hollow nano-objects made of DNA could trap viruses and render them harmless
To date, there are no effective antidotes against most viral infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell...

To date, there are no effective antidotes against most virus infections. Scientists have now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell cultures. It may also prove successful against corona viruses.
A rapid method to quantify antibodies against SARS-CoV-2

Scientists have developed a rapid, highly accurate test to detect antibodies against the spike protein of SARS-CoV-2 in human serum, opening a new avenue for understanding the full extent of the pandemic and evaluating the effectiveness of vaccines.
Biomolecular bonsai: Controlling the pruning and strengthening of neuron branches
- ScienceDaily
- 21/7/15 16:30
How neuronal circuits remodel themselves over time, especially during early development, is a major question in neurobiology. Using mice, researchers have uncovered a biomolecular mechanism behind the strengthening of connections from neurons called mitral cells. The team found that the protein BMPR-2 is a key regulator of selective stabilization of neuron branching and that strengthening of a...
