Throughout the densely-populated country of Bangladesh, a lack of access to clean drinking water is responsible for a variety of debilitating and often-lethal infections. Soon, however, residents could filter virtually all harmful microbes out of their water, using paper derived from algae.
The size of a cell is determined by a combination of synthesis, self-assembly, incoming matter and the balance of mechanical forces. Such processes operate at the single-cell level, but they are deeply interconnected with cell-cycle progression, resulting in a stable average cell size at the population level. Here, we examine this phenomenon by reviewing the physics of growth processes that operate at vastly different timescales, but result in the controlled production of daughter cells that are close copies of their mothers. We first review the regulatory mechanisms of size at short timescales, focusing on the contribution of fundamental physical forces. We then discuss the multiple relevant regulation processes operating on the timescale of the cell cycle. Finally, we look at how these processes interact: one of the most important challenges to date involves bridging the gap between timescales, connecting the physics of cell growth and the biology of cell-cycle progression.
Listen up, pet owners! Earlier this summer, several dogs in North Carolina, Georgia, and Texas perished after coming into contact with toxic blue-green algae. Although this may seem pretty far from home, it’s really a countrywide problem. The same toxic algae has even been spotted in Nevada, so you’ll definitely want to be on the lookout for this nasty stuff. Not only can it cause a variety of symptoms in humans, but it’s considered deadly for animals. Keep reading and learn how you can keep an eye out for algal blooms and keep your pets safe during your adventures.
Had you heard about this toxic blue-green algae that’s already killed several dogs this year? This stuff definitely isn’t to be taken lightly.
Samsung will release a smartphone using new fast chargoing graphene battery technology that can fully charge in under 30 minutes according to gadgets leaker Evan Blass (@EVLeaks).
Samsung will release a smartphone powered by new graphene battery technology that can fully charge in under 30 minutes in 2020, or possibly 2021. This will be three to five times faster than today’s lithium-ion batteries which take about 90 minutes to charge.
In 2017, Samsung Advanced Institute of Technology (SAIT) announced they had developed a “graphene ball,” a unique battery material that enables a 45% increase in capacity, and five times faster-charging speeds than standard lithium-ion batteries. The breakthrough provides promise for the next generation secondary battery market, particularly related to mobile devices and electric vehicles. In its research, SAIT collaborated closely with Samsung SDI as well as a team from Seoul National University’s School of Chemical and Biological Engineering.

Astrobiologists have sent 18 different strains of bacteria up to the International Space Station.
They’re not meant to contaminate the already-kinda-gross orbital research center, but rather to determine whether the mineral-leaching microbes could help astronauts mine space rocks during future missions, Space.com reports.
If the so-called BioRock experiment pans out, the researchers behind the experiment argue that it could help humanity turn space rocks on the Moon or Mars into farmable soil for future human settlements.

Genetics hold far more sway over the mouse microbiome than transient environmental exposures, researchers reported July 26 in Applied and Environmental Microbiology. The results appear to contradict previous studies in humans that have found environmental factors to be more influential than genetics, and they add to an ongoing dialogue in the microbiome research community over how much control we hold over the bacterial communities in our guts.
Hila Korach-Rechtman, a microbiologist at the Israel Institute of Technology in Haifa, set out to identify the microbes in mice that become a fixture in the gut after being introduced through the environment. “We really wanted to find these bacteria that can be transferred and remain in the host, even though they have different genetics,” she says.
Newly discovered life forms inside our bodies profoundly affect our health – and provide a glimpse of the vast and mysterious biological “dark matter” within us.
