Introduction & Purpose
Knowledge update and Industry update at Skyline University College (SUC) is an online platform for communicating knowledge with SUC stakeholders, industry, and the outside world about the current trends of business development, technology, and social changes. The platform helps in branding SUC as a leading institution of updated knowledge base and in encouraging faculties, students, and others to create and contribute under different streams of domain and application.

Hubble reveals millions of stars at centre of our galaxy

Washington, April 1 (IANS) Delving deep into the heart of our Milky Way galaxy, NASA's Hubble Space Telescope has revealed a rich tapestry of more than half a million stars at its core.

Except for a few blue foreground stars, the stars are part of the Milky Way's nuclear star cluster - the most massive and densest star cluster in our galaxy. 

So packed with stars, it is equivalent to having a million suns crammed between us and our closest stellar neighbour Alpha Centauri. 

At the very hub of our galaxy, this star cluster surrounds the Milky Way's central supermassive black hole which is about four million times the mass of our sun.

Astronomers used Hubble's infrared vision to pierce through the dust in the disk of our galaxy that obscures the star cluster. 

Hubble's sharp vision allowed astronomers to measure the movements of the stars over four years. 

Using this information, scientists were able to infer important properties such as the mass and structure of the nuclear star cluster. 

The motion of the stars may also offer a glimpse into how the star cluster was formed -- whether it was built up over time by globular star clusters that happen to fall into the galaxy's centre, or from gas spiraling in from the Milky Way's disk to form stars at the core.

The picture, spanning 50 light-years across, is a mosaic stitched from nine separate images from Hubble's Wide Field Camera 3. 

The centre of the Milky Way is located 27,000 light-years away. 

Astronomers estimate that about 10 million stars in this cluster are too faint to be captured in this image.​

Forgetting process helps us adapt to new surroundings

London, April 1 (IANS) Forgetting can be the result of an active deletion process in the brain rather than a failure to remember -- a mechanism that helps us adapt our behaviour according to the surroundings, says a new study.

The findings could point towards new ways of tackling memory loss associated with conditions such as Alzheimer's disease and other types of dementia.

"Our study looks at the biological processes that happen in the brain when we forget something,” said Oliver Hardt from University of Edinburgh in Scotland.

"The next step is to work out why some memories survive whilst others are erased. If we can understand how these memories are protected, it could one-day lead to new therapies that stop or slow pathological memory loss," Hardt said.

The findings were published in The Journal of Neuroscience.

The study conducted in rats could also help scientists to understand why some unwanted memories are so long-lasting - such as those of people suffering from post-traumatic stress disorders.

Memories are maintained by chemical signalling between brain cells that relies on specialised receptors called AMPA receptors. 

The more AMPA receptors there are on the surface where brain cells connect, the stronger the memory.

The team found that the process of actively wiping memories happens when brain cells remove AMPA receptors from the connections between brain cells.

Over time, if the memory is not recalled, the AMPA receptors may fall in number and the memory is gradually erased.

Blocking the removal of AMPA receptors with a drug that keeps them at the surface of the cell stopped the natural forgetting of memories, the study found.​

One-two cup of coffee daily may cut colorectal cancer risk

New York, April 1 (IANS) Drinking black, decaf or even instant coffee daily can lower the risk of developing colorectal cancer, finds a study.

Moderate coffee consumption, between one to two servings a day, was associated with a 26 percent reduction in the odds of developing colorectal cancer after adjusting for known risk factors.

Moreover, the risk of developing colorectal cancer continued to decrease to up to 50 percent when participants drank more than 2.5 servings of coffee each day. 

"We found that drinking coffee is associated with lower risk of colorectal cancer and the more coffee consumed, the lower the risk," said lead researcher Stephen Gruber from University Of Southern California.

The study, published in the journal Cancer Epidemiology, Biomarkers & Prevention, examined over 5,100 participants who had been diagnosed with colorectal cancer within the past six months, along with an additional 4,000 participants with no history of colorectal cancer to serve as a control group. 

A questionnaire also gathered information about many other factors that influence the risk of colorectal cancer, including family history of cancer, diet, physical activity and smoking.

The indication of decreased risk was seen across all types of coffee, both caffeinated and decaffeinated.

Caffeine and polyphenol compounds present in coffee can act as antioxidants, limiting the growth of potential colon cancer cells. 

"The good news is that our data presents a decreased risk of colorectal cancer regardless of what flavor or form of coffee you prefer," said study co-author Stephanie Schmit. 

"While the evidence certainly suggests this to be the case, we need additional research before advocating for coffee consumption as a preventive measure," said Gad Rennert from Clalit National Israeli Cancer Control Center in Haifa, Isreal.​

Russia becomes world's leading wheat exporter

Patients with skin infections hardly complete antibiotic doses

New York, March 29 (IANS) Patients with skin infections are less likely to take all their prescribed antibiotic doses after leaving the hospital, resulting in new infection or needing additional treatment for the existing skin infection, says a study.

The researchers found that patients with S. aureus skin and soft tissue infections took, on average, just 57 percent of their prescribed antibiotic doses after leaving the hospital.

"These findings suggest that we need better methods to have patients receive antibiotics for skin infections, such as counselling them on the importance of adhering to the medication dosing or by using newer antibiotics that require only once-weekly dosing," said lead researcher Loren Miller from Harbor-UCLA Medical Centre in California, US.

The study, published in the journal Antimicrobial Agents and Chemotherapy, followed 188 patients who had been hospitalised and suffered S. aureus associated skin and soft tissue infections. 

The researchers measured antibiotic dosing by using medication containers fitted with electronic caps that reported when the patient opened the antibiotic container. 

By using this measurement system, the researchers found a large discrepancy in patient reports and the electronic measurement. 

Patients reported taking, on average, 96 percent of their medication, or nearly twice the 57 percent reported by the electronic caps.

The researchers were able to obtain complete records on 87 out of the 188 patients. Of the 87 patients, 40 needed additional treatment within 30 days of leaving the hospital. They had a new skin infection, required incision and drainage of their infections or new antibiotics.​
