Live fast, die young

A recent study found that plant species living in urban backyards are closer related to each other and live shorter than those in rural areas. The study, conducted by Jeannine Cavender-Bares and Sonja Knapp, analyzed the diversity of plant species in private yards in Minneapolis and compared it to nearby natural ecosystems.

The sea as a rubbish tip

A team of researchers has proposed standardised guidelines for the recording and characterisation of microplastic particles in the sea. By analysing 68 scientific publications, they found that the results are difficult to compare due to varying methods used. However, they discovered that using a net with a mesh of 85 micrometres can fi...

KIT: Processes at the surface of catalysts

Researchers use infrared spectroscopy to study processes at surfaces of oxides used as catalysts, finding oxygen defects act as active centers and increase catalytic activity. The method allows for precise measurements of vibration frequencies, revealing defect densities in real catalyst powders.

How muscle cells seal their membranes

Muscle cells have efficient systems to seal holes in their plasma membranes. Researchers at KIT and Heidelberg University observed membrane repair in real-time using a novel imaging method. They found that membrane vesicles form a repair patch, which is sealed off from the extracellular environment.

Fiercer competition for quicker innovations

A study by KIT's Institute for Technology Assessment and Systems Analysis reveals that fiercer technical competition in Japan drives innovative mobile services. European operators are recommended to adopt similar measures, such as unlicensed radio spectrum usage and new licensing schemes, to regain competitiveness.

CeBIT: Robot obeys commands and gestures

At CeBIT, Karlsruhe Institute of Technology and FZI Research Center present interactive robots, safe cloud computing and virtual insights in the body. The humanoid kitchen robot ARMAR learns by watching and adapting to human gestures, while simulations open up new perspectives for complex problems.

The molecular basis of touch sensation

MDC researchers have identified a crucial function of the c-Maf gene in the development of neurons responsible for mechanosensory function. In mice with deleted c-Maf, high-frequency vibrations are not detected, leading to impaired touch sensation and early-onset cataracts.

Scientists make iron transparent

Researchers at DESY have successfully made atomic nuclei transparent using X-ray light, a crucial step towards developing quantum computers. This achievement demonstrates the effect of electromagnetically induced transparency (EIT) in atomic nuclei and has significant implications for the future of quantum computing.

No brakes on breast cancer cells

Researchers have discovered a microRNA, miR-520, that suppresses NFkappaB and TGF-b signaling pathways in breast cancer cells. This finding suggests that miR-520 may act as a tumor suppressor and could lead to new treatment options for ER-negative breast cancer.

How long do electrons live in graphene?

Researchers at Helmholtz-Zentrum Dresden-Rossendorf have measured the lifetime of electrons in graphene in lower energy ranges. The study reveals that the energy of light particles and atomic lattice oscillations influence electron lifetimes, with longer lifetimes observed when excitation energies are lower than lattice oscillations.

Simultaneous ice melt in Antarctic and Arctic

A recent study published in Science reveals that the Antarctic and Arctic ice sheets experienced simultaneous melting 19,000 years ago. This finding suggests that Antarctica was not as climatically isolated as previously thought, with the two hemispheres reacting more closely to climate change.

Earthquakes: Water as a lubricant

Researchers found that rock water acts as a lubricant, causing significant differences in mechanical properties along the fault at depth. This supports the idea that fluids play a key role in the onset of earthquakes, and tremor signals are linked to areas with trapped fluids.

Using Viagra to combat malignant melanoma

Researchers have found that sildenafil, the active ingredient in Viagra, can neutralize chronic inflammation caused by malignant melanoma, allowing tumor-specific T cells to function properly. This study suggests that Viagra may improve treatment results for people with melanoma by boosting antitumor immunity.
