A cosmic kaleidoscope

At first glance, this cosmic kaleidoscope of purple, blue and pink offers a strikingly beautiful — and serene — snapshot of the cosmos. However, this multi-coloured haze actually marks the site of two colliding galaxy clusters, forming a single object known as MACS J0416.1-2403 (or MACS J0416 for short).

MACS J0416 is located about 4.3 billion light-years from Earth, in the constellation of Eridanus. This new image of the cluster combines data from three different telescopes: the NASA/ESA Hubble Space Telescope (showing the galaxies and stars), the NASA Chandra X-ray Observatory (diffuse emission in blue), and the NRAO Jansky Very Large Array (diffuse emission in pink). Each telescope shows a different element of the cluster, allowing astronomers to study MACS J0416 in detail.

As with all galaxy clusters, MACS J0416 contains a significant amount of dark matter, which leaves a detectable imprint in visible light by distorting the images of background galaxies. In this image, this dark matter appears to align well with the blue-hued hot gas, suggesting that the two clusters have not yet collided; if the clusters had already smashed into one another, the dark matter and gas would have separated. MACS J0416 also contains other features — such as a compact core of hot gas — that would likely have been disrupted had a collision already occurred.

Together with five other galaxy clusters, MACS J0416 is playing a leading role in the Hubble Frontier Fields programme, for which this data was obtained. Owing to its huge mass, the cluster is in fact bending the light of background objects, acting as a magnifying lens. Astronomers can use this phenomenon to find galaxies that existed only hundreds of million years after the big bang.

For more information on both Frontier Fields and the phenomenon of gravitational lensing, see Hubblecast 90: The final frontier.

How Cancer Affects Your Brain - October 8, 2017 - Your brain is in charge of everything your body does, including vision, hearing, speech, and movement. As brain cancer grows, it presses on and damages areas that control these things. That can lead to complications like headaches, seizures, vision and hearing loss, and balance issues. Your doctor will help you manage these problems while you get treatments for your cancer.

Fatigue
A lot of people with brain cancer deal with this. You feel exhausted because your body uses a lot of energy to fight off the tumor. Cancer-related fatigue isn't normal tiredness. It wipes you out. The cancer also makes it harder for you to sleep soundly. Even when you can sleep, it doesn't always relieve the weariness. To curb fatigue, break up tasks into small chunks and take rest breaks during the day.

Headaches
About half of people with brain cancer get headaches. The tumor itself doesn't cause pain. But as it grows, it can press on sensitive nerves and blood vessels in the brain. Headaches can last for several hours. They can feel dull, aching, pounding, or throbbing. They’re often worse in the morning or can flare up when you cough or exercise. Your doctor can prescribe medicine to help control the pain.

Nausea and Vomiting
A tumor can make you sick to your stomach if it presses on certain areas of your brain. Cancer treatments like radiation and chemotherapy also cause nausea and vomiting. "Anti-emetic" medicines relieve nausea. They come in a liquid, tablet, and capsule -- or as a suppository if you're too sick to swallow medicine. Call your doctor if you can't keep down any foods or fluids, or you've been throwing up for more than 24 hours.

Personality and Mood Changes
More than half of people with brain cancer have personality or mood changes. It's common to feel more angry, withdrawn, anxious, or irritable than usual. Some of these changes may be part of your response to your cancer diagnosis and treatment. Others start when the tumor grows into areas of your brain that control mood and emotion. Talk with your doctor or a mental health specialist. Therapy can help you manage what you're going through.

Speech and Language Problems
Cancer can affect parts of your brain that help you speak and process language. You might struggle to find the right words, or mix up words when you describe objects ("chair" instead of "table,” for instance). It can also be harder to understand what other people say, or to follow a conversation. Language problems can be frustrating. Relax and slow down when you speak. A speech and language therapist can also help with communication.

Memory Loss
If you're more forgetful, it could be due to both your cancer and its treatments. Tumors can harm short-term and long-term memory, depending on their location. Chemotherapy and other treatments affect concentration and leave you mentally foggy. You may hear it called "chemo brain." Use a notebook, daily planner, and smartphone apps to remind you. An occupational therapist can show you how to make work and home tasks easier.

Vision Problems
A brain area called the occipital lobe processes the images your eyes see. A tumor in this part of the brain could affect your vision. Blurred vision, double vision, and floating spots can all be signs of a brain tumor. Your sight might go gray when you stand up or change position quickly. If you have these symptoms, see your doctor for a vision test. Surgery and other treatments that shrink the tumor can improve vision problems.

Hearing Loss
A tumor can put pressure on the nerves in your inner ear that move sound from your ear to your brain. Depending on where the tumor is, you might first lose the ability to hear high-pitched or low-pitched sounds. Ringing in the ears is also common. The hearing loss can come on slowly, and it might only be in one ear. See your doctor for a hearing test and treatment options.

Balance Issues
The cerebellum, an area in the lower part of your brain, controls your coordination and balance. This region helps keep you steady on your feet. A tumor in the cerebellum can throw off your balance and cause you to stumble or drop things. If you have balance problems, see a physical therapist. You might need a walker or cane to help you get around safely. Wear shoes with non-skid soles, and avoid walking on uneven or slippery surfaces.

Deep Vein Thrombosis (DVT)
Tumors release chemicals that make your body more likely to form blood clots. Nearly 1 in 5 people with brain tumors get deep vein thrombosis (DVT), a clot in a deep vein in the leg. If the clot moves into your lungs (pulmonary embolism), it could be life-threatening. See a doctor if you have swelling, redness, and tenderness in your leg. Taking blood thinners will stop the clot from getting bigger and prevent new clots from forming.

Seizures
About 60% of people with brain cancer get seizures, which are sudden bursts of abnormal electrical activity in the brain. Tumors may trigger them by changing brain cells or chemicals in a way that makes nerve cells fire too often. During a seizure, some people shake. Others stare off into space. Anti-seizure medicines can help. Also, avoid triggers, like loud noises or too little sleep.

Numbness and Weakness
A brain area called the parietal lobe helps you process the sensation of touch. A tumor in this part of your brain can cause numbness, or a tingling sensation that feels like pins and needles. Often the numbness affects only one side of your body, such as one arm or leg. One side of your body might also be weaker than the other. Tell your doctor about these symptoms.

Treating Your Cancer
The treatments you get to shrink your cancer will also ease its complications and can include:

Surgery to remove as much of the tumor as possible.
Radiation therapy uses high-energy X-rays to destroy cancer cells or slow their growth.
Chemotherapy medicines kill cancer cells.
Targeted therapy attacks the parts of cancer cells that help them grow and multiply.

When to Call Your Doctor
You’ll see your medical team often for your brain cancer treatment. Tell your doctors about any symptoms that are new or changing, including:

Seizures
Confusion
Extreme fatigue
Vision loss
Hearing problems
Loss of balance
Severe headaches
Trouble thinking or speaking

In taking the helm of Thor: Ragnarok, Taika Waititi not only made a career leap for himself, but a huge leap for indigenous representation behind the camera. With a budget of approximately $180 million, Ragnarok is the sort of opportunity that big studios almost never hand to an indigenous director – and so Waititi used his position to include others. From Easter eggs to shadowing opportunities for indigenous filmmakers, from an opening Karakia ceremony to avoiding appropriation, Waititi worked to bring better representation and inclusion to the Ragnarok set.

Fun with names. "A few years ago, the climate adaptation researcher Ben Smith—then a Ph.D. student at Kings College London—was working on his dissertation, about the effectiveness of water restoration projects in the United Kingdom. As with most scholarly projects, this involved spending hours and hours with the same information.

“I’d been staring at lists of rivers… [for] far too much time,” he says, when certain patterns of terminology began emerging. While the northern U.K. was squiggled all over with “burns,” the southeast was instead full of “nants” and “afons.”

“I got interested in the way [the words] varied between regions,” says Smith. So he decided to start mapping them. This year, inspired by a query from the landscape linguist Robert McFarlane, he returned to the project, and recently completed a set of maps of the U.K., twisted all over with different words for “stream.”"

While Joel Embiid the No. 3 Pick in the 2015 draft scored a game- high 30 Points and grabbed 9 Rebounds. While Covington ended up scoring 13 Points as the 76ers would never trail during tonight's game to win their first game of the season.

The Pistons who pulled off a 21 Point comeback vs the Knicks in their last game couldn't turn things around tonight as no one really stepped up to have a great game. Andre Drummond had 14 Points and 14 Rebounds while Reggie Jackson scored 16 Points while dishing out 7 Assists. With 15 Points from Bradley.

76ers Record: 1-3
Pistons Record: 2-2

There Goes My Everything #1 - Jack Greene
#purecountry #livemusic
There goes my only possession
There goes my everything
I hear footsteps slowly walking
As they gently walk across a lonely floor
And a voice is softly saying
Darling, this will be goodbye forever more
There goes my reason for living
There goes the one of my dreams
There goes my only possession
There goes my everything
As my memory turns back the pages
I can see the happy tears we had before
Now the love that kept this old heart beating
Has been shattered by the closing of the door
There goes my reason for living
There goes the one of my dreams
There goes my only possession
There goes my everything

Neuroscientists build case for new theory of memory formation

Learning and memory are generally thought to be composed of three major steps: encoding events into the brain network, storing the encoded information, and later retrieving it for recall. Two years ago, MIT neuroscientists discovered that under certain types of retrograde amnesia, memories of a particular event could be stored in the brain even though they could not be retrieved through natural recall cues. This phenomenon suggests that existing models of memory formation need to be revised, as the researchers propose in a new paper in which they further detail how these "silent engrams" are formed and re-activated. The researchers believe their findings offer evidence that memory storage does not rely on the strengthening of connections, or "synapses," between memory cells, as has long been thought. Instead, a pattern of connections that form between these cells during the first few minutes after an event occurs are sufficient to store a memory. "One of our main conclusions in this study is that a specific memory is stored in a specific pattern of connectivity between engram cell ensembles that lie along an anatomical pathway. This conclusion is provocative because the dogma has been that a memory is instead stored by synaptic strength," says Susumu Tonegawa, the Picower Professor of Biology and Neuroscience, the director of the RIKEN-MIT Center for Neural Circuit Genetics at the Picower Institute for Learning and Memory, and the study's senior author.

The Dehydration of Water Worlds via Atmospheric Losses

"There are currently about fifty known exoplanets with diameters that range from Mars-sized to several times the Earth's and that also reside within their stars' habitable zone – the orbital range within which their surface temperatures permit water to remain liquid. A "water world" is an extreme case, an exoplanet defined as being covered by a deep ocean, perhaps as deep as hundreds of kilometers, and among these fifty are several that might be candidates for this category. Astronomers note that at least two of the terrestrial planets in our solar system, Earth and Venus, may possibly also have been water worlds early in their evolution."
