Three to four cups of coffee a day linked to longer life – Drinking coffee is “more likely to benefit health than to harm it” for a range of health outcomes, say researchers in The BMJ today. Science Daily

‘Arrow of time’ reversed in quantum experiment – Your lukewarm cup of coffee won’t suddenly heat itself up, no matter how long you put off the trek to the microwave. But the same rule doesn’t necessarily apply to quantum systems. Like chilly air warming a mug, heat can spontaneously flow from a cold quantum particle to a hotter one under certain conditions, researchers report November 10 at arXiv.org. This phenomenon seems to reverse the “arrow of time,” the idea that natural processes run forward but not in reverse (SN: 7/25/15, p. 15). Science News

Republicans Want To Force The Critically Endangered Red Wolf Into Extinction – The red wolf, Canis rufus, currently exists only as a small population in one part of North Carolina.

Common cold viruses reveal one of their strengths – Common cold season is back, which has people wondering why we catch the same virus, year after year. Why don’t we ever develop immunity against the common cold? Professor Pierre Talbot at INRS has known about the incredible variability of coronaviruses for some time. They’re responsible for the common cold as well as many other infections, including neurological diseases. Along with his research associate Marc Desforges, Professor Talbot worked on a study recently published in Nature Communications about the ways in which coronaviruses adapt and evolve, becoming ever more effective at infecting hosts without being defeated by the immune system.

When the brain’s wiring breaks – Among all the bad things that can happen to the brain when it is severely jolted — in a car accident, for example — one of the most common and worrisome is axon damage. Axons are the long stalks that grow out of the bodies of neurons and carry signals to other neurons. They are part of the brain’s “wiring,” and they sometimes grow to amazing lengths — from the brain all the way down to the spinal cord. But axons are thin and fragile. When the brain receives a strong blow, axons are often stressed past their structural limits. They either break or swiftly degenerate. Science Daily

Superbugs may meet their match in these nanoparticles – Antibiotics may have a new teammate in the fight against drug-resistant infections. Researchers have engineered nanoparticles to produce chemicals that render bacteria more vulnerable to antibiotics. These quantum dots, described online October 4 in Science Advances, could help combat pathogens that have developed resistance to antibiotics (SN: 10/15/16, p. 11).

Secret Supereruption That Once Changed The World Found In North America – Yellowstone’s supervolcano gets all the attention these days, but it’s not the only vessel of apocalyptic eruptions. Today, there are several spots around the world that could bring about a game-changing eruption, and volcanologists are always on the hunt for ancient ones that until now have slipped beneath the radar.

Turns Out The Great Barrier Reef Can Actually Heal Itself, But We Have to Help It – he Great Barrier Reef is suffering from recent unprecedented coral bleaching events. But the answer to part of its recovery could lie in the reef itself, with a little help. In our recent article published in Nature Ecology & Evolution, we argue that at least two potential interventions show promise as means to boost climate resilience and tolerance in the reef’s corals: assisted gene flow and assisted evolution.

How to make the cosmic web give up the matter it’s hiding – Evidence is piling up that much of the universe’s missing matter is lurking along the strands of a vast cosmic web. A pair of papers report some of the best signs yet of hot gas in the spaces between galaxy clusters, possibly enough to represent the half of all ordinary matter previously unaccounted for. Previous studies have hinted at this missing matter, but a new search technique is helping to fill in the gaps in the cosmic census where other efforts fell short. The papers were published online at arXiv.org on September 15 and September 29. Science News

Understanding antibiotic resistance

Dated: 15 August 2017

Read More: Understanding antibiotic resistance

Original Source (if any): N.A

Reference Material (if any):

  1. Antibiotics Disrupt Coordination between Transcriptional and Phenotypic Stress Responses in Pathogenic Bacteria
Summary:

Researchers from Boston College has uncovered new insights into how bacteria respond to stress by using Streptococcus pneumoniae. Antibiotic is a form of stressor and understanding how bacteria respond is key to figuring out why they become antibiotic resistant.

It turns out when faced with a common threat or stress such as nutrient deprivation, the bacteria mount a highly organized response. However, when faced with antibiotics, the response was highly disorganized, demonstrating that the organism has a hard time with this kind of stressor.

With the use of RNA sequencing and transposon insertion sequencing, the researchers were able to determine that genes rely on collaboration that enables the organism to mount a successful response. When dealing with a new stress, the gene collaboration was nearly ineffective.

This discovery will allow us to stress bad bacteria out and eradicate them.

Author’s Take:

I want to applaud the efforts of these researchers. I for one is very concern with the rising antibiotics resistance.

A tiny fraction of oceans could meet world’s fish demand

Dated: 14 August 2017

Read More: Tiny fraction of oceans could meet world’s fish demand

Original Source (if any): Seafood for Thought

Summary:

A study by scientists from UC Santa Barbara and researchers from Nature Conservancy, UCLA, and the National Oceanic and Atmospheric Administration found that nearly every costal country has the potential to meet its own domestic seafood needs through aquaculture.

To determine aquaculture’s global potential, the researchers identified areas where the conditions of the oceans are suitable enough to support farm by using parameters such as ocean depth, temperature, and the biological needs of 180 species of finish and bivalve mollusks, such as oysters and mussels. They also ruled out places that would conflict with other use of the oceans such as high shipping zones and marine protected areas, and excluded ocean depths that exceed 200 meters. Not all possible political and social constraints are also considered.

This will allow for the flexibility to think about and doing the best way for conservation, economic development and other uses.

Author’s Take:

I like to eat seafood but I’m also concern about the environmental fallout. Let’s say we over exploit a certain species of fish just to feed the demand. That will be bad for the whole ecosystem. By implementing aquaculture properly and taking advantage of the available space, I believe it is sustainable and more environmentally friendly.

New way of making hair grow by activating stem cells

Dated: 14 August 2017

Read More: New way to activate stem cells to make hair grow

Original Source (if any): UCLA scientists identify a new way to activate stem cells to make hair grow

Summary:

UCLA researchers found a new way to activate stem cells in hair follicle to make hair grow.

What the researchers found was the hair follicle stem cell metabolism is different from other cells in the skin. When these stem cells consume glucose, they process it to produce a metabolite called pyruvate. This pyruvate is either sent to their mitochondria or converted to another metabolite called lactate.

When the researchers observed this, they went to investigate what if the amount of pyruvate sent to the mitochondria is reduced, will it cause the stem cells to produce more lactate, which will then activate the cells and make hair grow faster.

The researchers were able to confirm the increase in lactate production accelerated hair growth in mice model.

Author’s Take:

This is definitely good news for those who are suffering from heavy hair loss.
