A huge black hole has re-awakened after 26 years of being dormant. The black hole is located about 7,800 light-years from Earth and is described by the European Space Agency as part of V404 Cygni, a binary system made of up the hole and a star. The last time activity was dedicated from V404 was back in 1989, but on June 15th NASA’s Swift satellite detected new bursts of gamma rays.

Coral Reef’s Building Resistance To Pollution
As species survive the increasing heat over time, they are building up a resistance, or “genetic rescue.” Scientists have discovered the certain types of coral in Australia’s Great Barrier Reef have developed elevated thermal tolerances. As long as one type of the coral’s parents come from a warmer lower-latitude location, they are actually able to survive far better than similar coral without such parents. Essentially, a piece of coral who has a parent that lived in a heated environment, you are able to withstand the heat. This means that the coral is naturally toughening up to protect itself from pollution.

Scientists Discover Stratosphere on Exoplanet
For years, scientists believed the stratosphere to be an atmospheric feature unique to planets within our own solar system. But in an recent journal entry, scientists reveal this isn’t exactly the case.
In case you don’t know, the stratosphere is a layer of the atmosphere (including our own on earth!) that is distinguished by two main characteristics. First, is temperature inversion. Simply put, the higher up you go in the stratosphere, the hotter it gets. This is opposed to layers like the troposphere, in which temperatures decrease with altitude (which is partially why your plane rides are a bit chilly). Secondly, the stratosphere contains particles which help absorb the sun’s rays. On Earth, we have the Ozone. On other planets, there are molecules called hydrocarbons. Until now, it was believed that exoplanets were just too hot to facilitate the presence of such son absorbing molecules. But WASP-33b, the exoplanet in question, apparently does have an atmospheric layer characterized by a temperature inversion– and scientists believe it to be caused by titanium oxide. In other words, it looks like there very well may be stratospheres in other star systems.

100 New Species Discovered Near in the Phillippines
Each year, scientists discover thousands of new species: 15,000 (an average of 40 per day) by some estimates. However a recent ocean adventure in Philippine waters yielded a potential discovery of 100 species in a single day. During a marine expedition this spring, a zoologist and his crew stumbled across a trove of sea slugs covering a section of the sea floor. The discovery– a clear opportunity for scientific discovery– was described as an “easter egg hunt”.

Why “Star Talk” is so Important
Neil deGrasse Tyson has represented the more approachable mainstream discourse in astrophysics and cosmological philosophy for quite some time, establishing himself as a well trusted figurehead of these two disciplines. Involved in the fields for more than thirty years, he gained significant fame from a number of television shows and podcasts, and saw an increased following after his 2014 adaptation of Carl Sagan’s Cosmos. Also an activist for social justice and race equality, Tyson is best known for his accessible interpretations and his ability to spark wonder about some of the more esoteric and thus forgotten realms of science. Examples include stellar evolution and the interconnectivity of humans with their universe. His 2012 youtube webisode show secured him a spot on National Geographic that will open late-night ears to his insight and change the way crucial scientific theories are received.
Neil DeGrasse Tyson’s personality alone attracts and inspires those who may not consider themselves well versed in the fields of science. His personal version of spirituality rings familiar as one that many can identify with: “For me, when I say spiritual, I’m referring to a feeling you would have that connects you to the universe in a way that it may defy vocabulary…the moment you learn something that touches an emotion rather than just something intellectual, I would call that a spiritual encounter with the universe.” His powerful belief in the interconnectivity of humanity with the universe sees beyond the temporal and transcends preconceived and existing notions of self and separation. This helps to progressively dissolve practical constructs like race and the social hierarchy while bringing people together under much grander philosophical discourse. Put simply, he brings people together with a fascination that never seemed so easy to possess.
There are few hosts as enthusiastic and entirely dedicated to his practice as Neil deGrasse Tyson is to the revisualization of the universe and all its mysteries. His show will discuss topics relevant to today’s concerns like space travel, extraterrestrial life, and the enigma of black holes. He reimagines, rephrases, and dissects the greatest wonders in topics that on first glance seem exclusive. But Tyson is nothing but excited to reach the masses on a series of questions he knows will incite inspiring debates and conversations that were never before so commonplace. “Star Talk”, which will invite everyone from erudite scholars to adored pop culture icons, will be the perfect merger of inaccessible scientific theories and casual late-night entertainment. It will give a relaxed approach to a number of puzzling mysteries, and will feature many celebrities giving their own perspectives on the issues.
Scientists Find Molecule That Delays Alzheimer’s
Alzheimer’s disease is one of the most debilitating and painful diseases that man has ever had the unfortunate chance to encounter. While there might be no pain for the person afflicted with it, the pain their family goes through as they watch the person they knew and loved become a shell is indescribable. While there has been decades of research into finding a cure for this terrible disease, it seems as though progress has never been made until now.
Scientists at the University of Cambridge have released a new study in Nature Structural & Molecular Biology that points to a victory in the long fight against alzheimer’s disease. Researchers have found that the onset of alzheimer’s can be delayed by a molecule that was found to occur naturally in the human brain. Studies in mice have already shown that this molecule puts a stop to many of the processes that lead to alzheimer’s and dementia. The molecule is called Brichos and while it won’t revert any damage that was already done, it will prevent any more damage from occurring.
One of the first signs of alzheimer’s is the formation of sticky clumps of proteins in the brain. Proteins, called amyloid betas, start folding in wrong shape and end up sticking together. These clumps continue to grow into fibers, called fibrils, and spread across the brain. Even though the brain has ways to deal with this sort of issue, it can quickly be overwhelmed and cause a chain reaction. The fibrils act like a catalyst for more clumps to form and the process is exponential as the disease progresses.
Brichos works by sticking to the amyloid fibrils, coating their exterior and preventing the formation of any more sticky clumps. Unfortunately, Brichos currently isn’t useful as a treatment source because it gets absorbed by the body too quickly to get an actual chance to work on the brain. However this discovery shows that the alzheimer’s process can be interrupted and that if we can find another molecule like Brichos then we have a real chance at stopping this tragic disease once and for all.

Word to the Wise: 4 Tips for Air Travel During the Holidays
It’s finally that time of the year again; the season for giving and the season to be thankful, the season for hot beverages on crisp evenings and perhaps most importantly, the season for sales and discounts. Everyone is on the sharp lookout for the hottest deals, be it a half-priced sweater or a stellar holiday package deal.
Traveling during the holiday season is a trend that has rapidly grown in the past few years and by the looks of it, it is a trend that is here to stay. More and more people are now keen on the idea of taking advantage of the competitive packages to escape to a warmer destination during the winter while some seek out adventurous winter sport trips. With everyone looking for a getaway, it is not surprising that traveling during the holidays is nothing short of a nightmare with overpacked airports, overbooked hotels and overwhelming delays due to inhospitable weather conditions.
Air travel is stressful enough on a regular day and during the holiday season, the prospect is made extra daunting by regular delays, extended waits for luggage, missed connections and cramped flights. The very thought of an unfortunate combination of the above mentioned air travel disasters is enough to make anyone cringe at the thought of traveling during the holidays. And of course, there is road travel with treacherous roads and ridiculous traffic, but that we can worry about another day. Assuming we make it past the icy death roads and the traffic that can inspire the most dramatic of road-rages, there are a few simple steps that can lead to more a peaceful air travel, even if a glitch-free trip can never really be guaranteed.
-
Plan in advance: Seems obvious enough and yet many a holiday trip has been marred by simple oversights that could easily be avoided by planning ahead. Pre-booking, re-confirming and double-checking are simple steps that may seem time consuming, but are more likely to save you time in the grand scheme of events. Also, planning ahead gives you the opportunity to snag the best deals, the off-peak cheaper flights and good travel dates.
-
Keep ample time in hand: There is almost always something left to do last minute and in all the hustle bustle, rushing to the airport, furiously praying for empty roads and green lights is not an uncommon scenario. The domino effect of this is that you will inevitably be five minutes behind schedule for the rest of the boarding process. Try to leave early and anticipate appropriate travel time to the airport. Also, flights delays are not uncommon at this time of the year; be mentally prepared for long waits and bring reading material to pass the time as you wait for your flight to be ready after de-icing.
-
Be prudent about packing: Most of us are guilty of overpacking most of the time. The idea of going to an unknown place and finding yourself sans an essential tool is enough to make most pack a flashlight for a trip to Paris and take a can-opener to the Bahamas. Most airlines now practice stringent baggage allowances and a lighter suitcase can save you money, and even time, if you can avoid checked baggages altogether. You really do not need that third pair of back-up glasses. Lose it.
-
Take care of your health: You do not want to contract flu and cold right before your holiday and spend the duration of your trip sneezing in pictures and being able to taste the foreign cuisine. Get a flu shot before your trip and use hand sanitizer as often as possible to avoid germs. Long time on aircrafts can lead to Deep Vein Thrombosis (DVT), clotting blood in your legs. Stretch and walk around for a few minutes every hour to avoid this.
Despite all the foresight, there will sometimes be a lost bag or two, a cold may sneak up on you as your plane takes off; some of us will still take that can-opener, just in case, and some of us will rush through the gates just as they are about to close. The important thing is to keep a positive outlook at times like this. Take a deep breath and troupe through the airport drama and keep your eye on the prize – the getaway you’ve been daydreaming about for months. For more winter travel tips, click here.

Not “Just Kids”
We, as a society, have a strange relationship with children that is intensely riddled with paradoxes, ironies, and contradictions. Thanks to the intense eye of media coverage, we feel our kids are in the most dangerous society history has ever seen– although social scientists have readily dismissed this absurd idea. Thinking of letting your young child play outside alone? Absolutely not! Some may interpret as abuse. And even if you are outside with your children supervising their exploration and interaction with the world around them, they better avoid climbing to the top of the slide, lest they fall to their untimely deaths– even if such an occurrence was simply an isolated incident. But scientific study seems to be making a case that more people are listening to, and parents are becoming more aware of the detrimental effects such overprotective behavior can have on their children.
But if we take special care to turn that coin over, and thoroughly examine the reverse, we hit a bit of a problem. While the research is encouraging parental and authority figures to take a step back from their childrens’ lives, it is certainly not telling them to treat young people as adults. But too many of us are doing it in a way we may not realize. And herein lies the great irony: the same parents who accompany their children everywhere and keep watch like an Orwellian Big Brother, in the name of “oh, but they’re just children!” could very well be harming them in another way, completely oblivious to the mental toll which it could potentially have, because “oh, but they’re just children!”
I’m talking about aggressive behavior between parents.
An article in Sciencedaily recently recapped the findings from a study done by New York University’s Steinhardt School of Culture, Education, and Human Development. The longitudinal study, first published in Pathology and Developmental Psychology, tracked the way that exposure to both physical and verbal aggression at home impacted the ability of a child to correctly identify and control his or her own emotions. Now, there have been similar studies conducted in the past, but those focused on immediate effects and the short term. This is the first such study that follows the subjects throughout childhood. In addition to these kinds of conflict, the study also demonstrated that any type of chaos or time in poverty could also have detrimental effects on a child’s developmental growth. It’s easy to see how fighting is stressful for both parental parties involved. However, when it is done in front of kids, we can only help but to wonder if the parents don’t worry about the effect their ill-communication is having on their children. Do the parents instead write it off simply by assuming the child knows better than to believe the arguments have anything to do with them? Evidently not, the study shows, as kids find these conflicts as emotionally taxing as the conflicting parties.
Now let’s take a closer look at the study itself. In general, the study sought to measure how exposure to a conflict heavy environment affected the ways in which children could identify and process negative emotions such as anger, fear, and sadness. The longitudinal range ran from ages of 2 years to 58 months. The researchers gathered sorta data by having parents complete questionnaires, disclosing such pertinent information as number of times the household moved, noise levels, cleanliness, the number of times the primary caregiver changed, and things of the like. This was calculated to determine the level of chaos present in a house, and plotted against the levels of stability. At the end of the study, when the children were at the ripe, wise age of 58 months, they were asked to do an exercise that involved identifying emotions. True to expectations, the children exposed to physical aggression between their parents did not perform well on the task. More unexpected though, was the finding that children whose parents engaged in more verbal conflicts, were much more attuned to their own emotions, and able to perform the task better.
More troubling though, was the discovery that the longer a child was exposed to these kinds of conflicts, the more likely they would be unable to adequately regulate their own negative emotions, such as sadness and fear. Unsurprisingly, this places them at higher risk for mental disorders such as depression and anxiety later on in life.
We should keep in mind that children’s minds are very plastic, very malleable. They’re always soaking in information that pertains to the world around them. To believe that they simply can’t process what’s going on, or will forget it in time, is not only dismissive of their human capacities in the moments, but also directly counter to the latest research in child development. Said research asserts that children are constantly learning, and that at birth our mind is far from a Rousseauian tabula rasa. In fact, children already have developed some expectations of the world around them in the womb. And if that can be discerned before birth, just imagine what the brain processes afterwards.

Understanding LUCA
All life forms have one common ancestor, in the form of a single-celled organism. However, for centuries, the question of how this single-celled organism has evolved into the variety of life forms now evident has plagued biologists. Research conducted by scientists at University College London can shed some light on the complex evolutions of this common ancestor, according to findings published in PLOS Biology and summarized in an article by Science Daily.
The research focused on the evolution of Life’s Last Universal Common Ancestor, otherwise known as the LUCA. The scientists built a model to monitor the changes in the membrane of the LUCA, in the hopes of examining how the ancestor is able to evolve into both bacteria and archaea—two types of single-celled organisms that have completely different cell membranes.
The model gave the LUCA a “leaky” membrane. Through the inclusion of this leaky quality to the membrane, the LUCA was powered by energy driven from its surroundings, suggesting that the LUCA originally lived in areas with ancient seawater. This seawater allowed protons, or positively charged particles, to mix with alkaline vent fluid. From there, the leaky membrane enabled the protons to leave cell, allowing for more protons to enter the power growth; therefore, the LUCA was able to adapt and evolve, to escape the seabed vents. In essence, the model showed all the steps the LUCA takes from being a strange cell to being the ancestor of all life today. Through these steps, the team was able to observe how LUCA can evolve into both bacteria and archaea.
In the future, the researchers, led by Victor Sojo, of the UCL CoMPLEX and Biosciences department and the first author of the study, hope to recreate the environment of the vents, as this is where it is believe life formed four billion years ago.
