#Coral-Like Nanoplates Help Remove Toxic Heavy metals from Water A new material that mimics coral could help remove toxic heavy metals like mercury from the ocean,
Toxic heavy metal ions like mercury, lead and arsenic are released into the water through human activity, including manufacturing and industrial processes.
One major source of toxic metal contamination is the ocean. When mercury pollutes the water
The mercury builds up in the food chain, ultimately resulting in toxic fish. According to THE WHO, between 1. 5 and 17 in every thousand children living in selected subsistence fishing populations showed cognitive impacts caused by the consumption of fish containing mercury.
Heavy metals are also toxic to corals: even at low concentrations, small amounts of heavy metal pollution can kill corals.
This heightened toxicity is due to coral being very efficient at collecting, or adsorbing, heavy metals. The researchers behind the new study have taken inspiration from this

which is the first and only FDA-approved heart failure monitoring device proven to significantly reduce hospital admissions.
The device is a sensor that is implanted in the pulmonary artery (PA) during a minimally invasive procedure.
Once implanted, the device can measure and transmit PA pressure from the patient back to their healthcare team.
Elevation in PA pressure appears even before changes in weight and blood pressure in the patient,
which are used traditionally as indirect measures of worsening heart failure. The new system allows patients to transmit daily sensor readings from their homes to their health care providers allowing for personalized

#New Smart Insulin Patch May Replace Injections for Diabetics By Beth Ellisonthe mart insulin patchis a thin square a couple of millimetres large.
The research team found that the new patch could reduce blood glucose levels in a mouse model of type 1 diabetes for as long as nine hours.
with further preclinical tests and human clinical trials to come. The future potential of the device is highlighted by co-senior author Zhen Gu, Phd, a professor in the Joint UNC/NC State department of Biomedical engineering:"
"The whole system can be personalized to account for a diabetic's weight and sensitivity to insulin,
diabetes is maintained currently with frequent finger prick tests and insulin shots to control blood glucose levels.
"Injecting the wrong amount of medication can lead to significant complications like blindness and limb amputations,
or even more disastrous consequences such as diabetic comas and death.""This research team have removed the risk of human error by emulating the natural insulin generators of the body beta cells.
The team tested the patch on a mouse model of type 1 diabetes and compared it to injecting insulin as standard.
Regular insulin injections can cause blood glucose levels to plummet dangerously low the patch has been found not to pose this risk.

#Novel Synthetic Biosensor Glows in Response to Conditions that Mimic TB Infection Robert Abramovitch, an MSU microbiologist,
a sulfa-based compound found in many prescription glaucoma drugs, actually turns off the bacterium's ability to invade the immune system.
"We found the compound reduces disease symptoms in mice.""According to Abramovitch, TB may not have eyes and ears,
One of these cues includes the infection's ability to detect ph -or acidity levels-which tells the disease it's being attacked by a host immune cell."
"The compound we found inhibits TB's ability to detect acidic environments, effectively blindfolding the bacterium
globally, carry the infection, but in most cases it lies dormant and the immune system is able to prevent it from spreading in the body."
"The immune system has difficulty clearing the infection and the TB bacterium is just waiting for the immune system to weaken."
"Abramovitch and his research team screened 273,000 different compounds in hopes of finding one that could possibly stop the disease.
By using a synthetic biosensor that glows green in response to conditions that mimic TB infection,
Yet, this elusive compound not only has the potential of preventing the disease from spreading, but Abramovitch suggests that it could help shorten the length of treatment

#Test unravels history of infection US researchers claim to have developed a single test that is able to identify past exposure to every known human virus infection,
The technique decodes the infection history imprinted in our immune response. The scientists hope that the test will eventually provide important insight into how viruses contribute to development of a range of diseases.
The work was published in the journal Science. During a virus infection, your immune system generates antibodies designed to fight the virus. Each antibody recognises a tiny fragment of the virus
and their interaction is very specific-they fit like a lock and key. Virus-specific antibodies can be long-lived;
often persisting many years after an infection has disappeared. So, your antibody repertoire represents a historical record of all of the viruses that have infected you.
This immunological catalogue has been used for years to identify past virus exposure, but the diagnostic tests routinely used have been limited to one,
or at most a few, different virus strains. Discovering connections Prof Stephen Elledge from the Harvard university Medical school US,
so it allows you to discover connections between different populations or different diseases amongst groups of people."
Antibodies present in a drop of human blood could then be used as bait to go fishing in this phage pool-only bacteriophage that express protein fragments recognised by the antibodies in the blood sample will be caught.
The data showed that the number of virus infections detected in people increased during life.
The study also suggested that those living in the US were exposed to fewer infections than people living in South africa, Thailand or Peru."
the sensitivity of the population to infection or practices in the country",commented Prof Elledge.
The greatest number of virus infections that were detected in any single individual was around 25,
or HIV infection could be massaged up to very respectable levels, I'd be nervous about using it as a diagnostic test to see
if an individual patient has HIV infection.""However, it will be a fabulous tool for looking at virus-disease associations
which are speculative, or even currently unknown. For example, primary biliary cirrhosis (PBC) has been reported, controversially, to arise from viral infection,
so it would be great to compare the virome of PBC patients with those without the disease.
Maybe you'd identify a consistent pattern suggesting a specific viral cause.""Indeed any other disease of unknown aetiology-identifying specific virome reactivity could give a major clue as to a causative agent."
"And the technique might also shed light onto why new treatments-immunotherapies-that are being deployed in the fight against cancers work in some individuals and not in others.
Prof Elledge commented:""It's possible that the people that respond to therapy are responding
because they are taking advantage of existing immune responses to viruses, so we are looking at correlation in these patients to previous viral exposures to see
if exposure to a particular virus makes it more likely to respond

#Bionic eye implant world first Surgeons in Manchester have performed the first bionic eye implant in a patient with the most common cause of sight loss in the developed world.
Mr Flynn said he was delighted"with the implant and hoped in time it would improve his vision sufficiently to help him with day-to-day tasks like gardening and shopping.
The Argus II implant manufactured by the US firm Second sight, has previously been used to restore some vision to patients who are blind as a result of a rare condition known as retinitis pigmentosa.
The operation, at Manchester Royal Eye Hospital, is the first time it has been implanted in a patient with age-related macular degeneration (AMD)
which affects at least half a million people in the UK to some extent. I met Ray Flynn last month,
on the morning of his surgery and he explained that although his retained his peripheral vision,
and was led by Paulo Stanga, consultant ophthalmologist and vitreo-retinal surgeon at Manchester Royal Eye Hospital and professor of ophthalmology and retinal regeneration at the University of Manchester.
In a test, two weeks after surgery, Mr Flynn was able to detect the pattern of horizontal,
vertical and diagonal lines on a computer screen using the implant. He kept his eyes closed during the test
so that the medical team could be sure that the visual information was coming via the camera on his glasses and the implant.
"The implant cannot provide any highly detailed vision -but previous studies have shown it can help patients to detect distinct patterns such as door frames and shapes.
Mr Flynn should learn how to interpret the images from the implant more effectively. Four more patients with dry AMD will receive the implant at Manchester Royal Eye Hospital,
as part of a clinical trial. Prof Stanga said:""We hope these patients will develop some central visual function
