Is theory on Earth's climate in the last 15 million years wrong?  

A key theory that attributes the climate evolution of the Earth to the breakdown of Himalayan rocks may not explain the cooling over the past 15 million years, according to a new study. The study could shed more light on the causes of long-term climate change. It centers on the long-term cooling that occurred before the recent global warming tied to greenhouse gas emissions from humanity.

Capturing extreme close-ups of cellular gene expression  

Scientists studying genetic transcription are gaining new insights into a process that is fundamental to all life. Transcription is the first step in gene expression, the process taking place within all living cells by which the DNA sequence of a gene is copied into RNA, which in turn (most generally speaking) serves as the template for assembling protein molecules, the basic building blocks of life.

Faults' hot streaks and slumps could change earthquake hazard assessments  

For more than a century, a guiding principle in seismology has been that earthquakes recur at semi-regular intervals according to a 'seismic cycle.' In this model, strain that gradually accumulates along a locked fault is completely released in a large earthquake. Recently, however, seismologists have realized that earthquakes often occur in clusters separated by gaps, and one research group now argues that the probability of a tremor's recurrence depends upon whether a cluster is ongoing -- or

However, the different locations in the AML cells where KIT induces cancer-specific signaling remain unclear. Now, a group of scientists has aimed to answer this question by using a newly synthesized compound (along with other existing ones) that targets intracellular transport, which may offer an attractive strategy to combat cancer.

As a result, depression and anxiety are two to three times more common in cancer patients than the general population. Experts propose that targeting cancer patients' mindsets could have an impact on their health, functioning, and well-being, and they call for more research in this field.

Corrosion resistance of steel bars in concrete when mixed with aerobic microorganisms  

Dissolved oxygen in pore solution is often a controlling factor determining the rate of the corrosion process of steel bars in concrete. This study reports on the corrosion resistance and polarization properties of steel bars in a mortar specimen mixed with aerobic microorganisms. The addition of the microorganisms in mortar mixtures led to higher corrosion resistance, which was confirmed by the reduced rate of oxygen permeability, based on cathodic polarization properties.

Why is the brain disturbed by harsh sounds?  

Neuroscientists have analyzed how people react when they listen to a range of different sounds, the aim being to establish the extent to which repetitive sound frequencies are considered unpleasant. Their results showed that the conventional sound-processing circuit is activated but that the cortical and sub-cortical areas involved in the processing of salience and aversion are also solicited. This explains why the brain goes into a state of alert on hearing this type of sound.
