How hard did it rain on Mars?
Heavy rain on Mars reshaped the planet ' s impact craters and carved out river-like channels in its surface billions of years ago, according to a new study. Scientists show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet ' s surface as we see on Earth. (Source: ScienceDaily Headlines)

Bacteria harness the lotus effect to protect themselves
Dental plaque and the viscous brown slime in drainpipes are two familiar examples of bacterial biofilms. Removing such bacterial depositions from surfaces is often very difficult, in part because they are extremely water-repellent. Scientists have now been able to show how such biofilms adapt their surface texture to repel water -- similar to leaves. (Source: ScienceDaily Headlines)

Stiffer soles are making life more comfortable for some diabetic patients
There isn ' t a one-size-fits-all approach when choosing the right footwear or inner sole to take away pressure from diabetic patients ' feet. The body mass index (BMI) of diabetics indicates how stiff or soft the cushioning material in shoes should be. New research provides the first scientific evidence to help healthcare professionals provide bespoke footcare to their diabetic patients. (Source: ScienceDaily Headlines)

Extreme weather has greater impact on nature than expected
An oystercatcher nest is washed away in a storm surge. Australian passerine birds die during a heatwave. A late frost in their breeding area kills off a group of American cliff swallows. Small tragedies that may seem unrelated, but point to the underlying long-term impact of extreme climatic events. (Source: ScienceDaily Headlines)

Defective intercellular connections cause hydrocephalus
A defective gene leads to changes in the cellular layer between cerebrospinal fluid and brain nervous tissue, thus causing a buildup of fluid in the brain. This link is the first known mechanism underlying genetic hydrocephalus. (Source: ScienceDaily Headlines)

From where will the next big earthquake hit the city of Istanbul?
Scientists reckon with an earthquake with a magnitude of 7 or greater in this region in the coming years. The extent of such seismic threat to this Turkish city of Istanbul actually depends on how strongly the tectonic plates are entangled and on the exact nucleation point of the earthquake. A team of researchers now presents a study indicating that the next major earthquake is more likely to originate in Istanbul ' s eastern Marmara Sea. (Source: ScienceDaily Headlines)

How plants use sunlight to tell time via cell protein signaling
Researchers have solved a key mystery of how plants tell time. Researchers learned a chemical bond in the protein Zeitlupe forms and breaks in reaction to sunlight at varying rates, signaling plants when to bloom, metabolize and store energy, and other functions. The discovery means plant clocks can be tuned by targeted mutations to plant proteins that may improve resistance to pathogens and crop yields. (Source: ScienceDaily Headlines)

A mammoth task: How do we decide which species to resurrect?
The resurrection of vanished species -- through cutting-edge technologies such as gene-editing -- should be targeted towards recently extinct species rather than ancient ones, according to a conservation biologist. He suggests that long-gone species such as the woolly mammoth would not be the best focus for de-extinction efforts. (Source: ScienceDaily Headlines)
