Under control to the very end -- how our cells kill themselves      (via sciencedaily.com)     Original source 

Every day, millions of cells die in our body. Other than generally assumed, cells do not simply burst at the end of their lives but rather, a specific protein serves as a breaking point for cell membrane rupture. Researchers have now been able to elucidate the exact mechanism at the atomic level.

A guide through the genome      (via sciencedaily.com)     Original source 

Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation.

How plants use sugar to produce roots      (via sciencedaily.com)     Original source 

Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. Botanists have demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to the research team leader.

Fossils of a saber-toothed top predator reveal a scramble for dominance leading up to 'the Great Dying'      (via sciencedaily.com)     Original source 

A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world's worst mass extinction 252 million years ago. Heading to South Africa allowed it to fill a gap in a faraway ecosystem that had lost its top predators.

Nitrate: Healthy heart or cancer risk? Meet nutrition's Jekyll and Hyde      (via sciencedaily.com)     Original source 

For a long time nitrate has been viewed warily, with previous research showing it could potentially be linked to causing cancer. However, it has subsequently bee revealed to have various cardiovascular health benefits. So, which is it? A new review of dietary nitrate research shows the answers to its health benefits or risks may lie in where it is sourced from.

Even slight traffic noise has a negative impact on work performance      (via sciencedaily.com)     Original source 

As cities are densified at a fast pace, there is now construction very close to roads and thoroughfares. It is already known that noise can have a negative impact on human health, but new research shows that as little as 40 decibels of traffic noise -- the typical level of background noise in an office environment or kitchen -- has a detrimental effect on cognitive performance.

Out of the frying pan: Coyotes, bobcats move into human-inhabited areas to avoid apex predators -- only to be killed by people      (via sciencedaily.com)     Original source 

Conservationists have argued that the presence of wolves and other apex predators, so named because they have no known predators aside from people, can help keep smaller predator species in check. New research shows that in Washington state, the presence of two apex predators -- wolves and cougars -- does indeed help keep populations of two smaller predators in check. But by and large the apex predators were not killing and eating the smaller predators, known as mesopredators. Instead, they drove the two mesopredator species -- bobcats and coyotes -- into areas with higher levels of human activity. And people were finishing the job.

In years after El Niño, global economy loses trillions      (via sciencedaily.com)     Original source 

Researchers report that the financial toll of the climate pattern known as El Niño can persist for several years and cost trillions in lost income worldwide. The study, which is among the first to evaluate the long-term costs of El Niño, found that the 1982 and 1997 events led to $4.1 trillion and $5.7 trillion in lost income in the five years following them. With El Niño projected to return this year, the researchers project that global economic losses for the 21st century will amount to $84 trillion as climate change potentially amplifies the events' frequency and strength.

Half of world's largest lakes losing water      (via sciencedaily.com)     Original source 

Fifty-three percent of the world's largest freshwater lakes are in decline, storing less water than they did three decades ago, according to a new study. The study analyzed satellite observations dating back decades to measure changes in water levels in nearly 2,000 of the world's biggest lakes and reservoirs. It found that climate change, human consumption and sedimentation are responsible.

Fossil of mosasaur with bizarre 'screwdriver teeth' found in Morocco      (via sciencedaily.com)     Original source 

Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent finds from Africa, it suggests that mosasaurs and other marine reptiles were evolving rapidly up until 66 million years ago, when they were wiped out by an asteroid along with the dinosaurs and around 90% of all species on Earth.

Cancer cells use a new fuel in absence of sugar      (via sciencedaily.com)     Original source 

Researchers have discovered a new nutrient source that pancreatic cancer cells use to grow. The molecule, uridine, offers insight into both biochemical processes and possible therapeutic pathways. The findings show that cancer cells can adapt when they don't have access to glucose.

Perfect 'pathogen' storm: Vibrio bacteria, Sargassum and plastic marine debris      (via sciencedaily.com)     Original source 

Little is known about the ecological relationship of Vibrio bacteria with Sargassum. Evidence also is sparse as to whether vibrios colonizing plastic marine debris and Sargassum could potentially infect humans. As summer kicks off and efforts are underway to find solutions to repurpose Sargassum, could these substrates pose a triple threat to public health? Results of a study representing the first Vibrio spp. genome assembled from plastic finds Vibrio pathogens have the unique ability to 'stick' to microplastics, harboring potent opportunistic pathogens.
