Lighting the way to infrared detection
Lighting the way to infrared detection
Physicists propose a new path to detect infrared radiation with outstanding sensitivity, allowing detection of signals as low as that of a single quantum of light. When using our webcam or cell phone camera, we experience the tremendous capabilities of cheap and compact sensors developed in the past decades for the visible region of the electromagnetic spectrum.

Newly discovered mechanism regulates myocardial distensibility
Newly discovered mechanism regulates myocardial distensibility
Immunofluorescence staining of the muscle tissue of a chronically diseased human heart under the confocal microscope. Two proteins in the sarcomeres, which give the tissue the characteristic striation pattern, were marked with antibodies and visualized by different fluorophore-conjugated antibodies: titin appears red and actinin green; the nuclei were stained blue.

Hints of life discovered on Venus
Hints of life discovered on Venus
A UK-led team of astronomers has discovered a rare molecule - phosphine - in the clouds of Venus, pointing to the possibility of extra-terrestrial 'aerial' life. The presence of life is the only known explanation for the amount of phosphine inferred by observations Paul Rimmer Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes - floating free of the scorching surface, but tolerating very high acidity.

Predicting the slow death of lithium-ion batteries
A new model offers a way to predict the condition of a battery's internal systems in real-time with far more accuracy than existing tools. In electric cars, the technology could improve driving range estimates and prolong battery life. Batteries fade as they age, slowly losing power and storage capacity.

To recreate ancient recipes, check out the vestiges of clay pots
The residue in these seven La Chamba pots retained evidence of all the meals prepared in them. (Photo courtesy of Melanie Miller) If you happen to dig up an ancient ceramic cooking pot, don't clean it. Chances are, it contains the culinary secrets of the past. A research team led by UC Berkeley archaeologists has discovered that unglazed ceramic cookware can retain the residue of not just the last supper cooked, but, potentially, earlier dishes cooked across a pot's lifetime, opening a window onto the past.

Let there be light and the process stops
Let there be light and the process stops
Researchers have discovered that they can use light-sensitive molecules to switch genetic networks on and off as required. Their finding gives rise to an easy method for dynamically controlling biotechnological substance production. Tetracycline (Tc), an antibiotic, and its derivative anhydrotetracycline (aTc) enjoy widespread use in biotechnology and synthetic biology.

New Analytical Methods for Longer-Lasting Lithium-ion Batteries
New Analytical Methods for Longer-Lasting Lithium-ion Batteries
How can the lithium-ion battery (LIB) be further improved? To answer this question, MEET scientists around Lenard Hanf developed new methods for capillary electrophoresis. For the first time, this enables a detailed analysis of the transition metal dissolution from LIB cathode materials or the current collector - such as manganese or copper.

Asphalt adds to air pollution, especially on hot, sunny days
Asphalt is a near-ubiquitous substance - it's found in roads, on roofs and in driveways - but its chemical emissions rarely figure into urban air quality management plans. A new study finds that asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days. Yale researchers observed that common road and roofing asphalts produced complex mixtures of organic compounds, including hazardous pollutants, in a range of typical temperature and solar conditions.

New anode material could lead to safer fast-charging batteries
Researchers Haodong Liu and Ping Liu hold batteries made with the disordered rocksalt anode material they discovered, standing in front of a device used to fabricate battery pouch cells. Scientists at UC San Diego have discovered a new anode material that enables lithium-ion batteries to be safely recharged within minutes for thousands of cycles.

A laser cutter could create new wave of bioelectronics
On a simple coffee table sits an inexpensive commercial laser cutter, usually meant for modifying wood or plastic. However, in the lab of University of Chicago scientists Vishnu Nair and Bozhi Tian, what comes out is not engraved wood but a small bioelectronic device that could save lives. It all starts with a compound called polydimethylsiloxane, or PDMS, which is a type of elastomer-a very elastic, stretchable material. However, a laser can transform the PDMS into a dense silicon carbide layer that is useful for electronics.

Ceramic cooking pots record history of ancient food practices
Ceramic cooking pots record history of ancient food practices
Analysing three components of ceramic cooking pots - charred remains, inner surface residues and lipids absorbed within the ceramic walls - may help archaeologists uncover detailed timelines of culinary cooking practices used by ancient civilisations. The findings, from a year-long cooking experiment led by the University of California, University of Bristol and the Bernice Pauahi Bishop Museum in Hawaii, are published this week in the journal Scientific Reports .

Quantum Simulation of Quantum Crystals
International research team describes the new possibilities offered by the use of ultracold dipolar atoms The quantum properties underlying crystal formation can be replicated and investigated with the help of ultracold atoms. A team led by Dr. Axel U. J. Lode from the University of Freiburg's Institute of Physics has now described in the journal Physical Review Letters how the use of dipolar atoms enables even the realization and precise measurement of structures that have not yet been observed in any material.

Fuel cells for hydrogen vehicles are becoming longer lasting
An international research team led by the University of Bern has succeeded in developing an electrocatalyst for hydrogen fuel cells which, in contrast to the catalysts commonly used today, does not require a carbon carrier and is therefore much more stable. The new process is industrially applicable and can be used to further optimize fuel cell powered vehicles without CO2 emissions.
