  • Something in Your Eyes May Reveal if You're at Risk of Early Death, Study Shows

    A quick and pain-free scan of the human eyeball could one day help doctors identify 'fast agers', who are at greater risk of early mortality. Getting older obviously has an impact on everybody's body, but just because two people have the same number of years under their belt doesn't mean they are physically declining at the same rate. Looking deep into a person's eyes could be a far better way to measure their true biological age, and this could provide a glimpse into the future health of patients. A machine learning model has now been taught to predict a person's...

    A total of 280 patients presenting 280 eyes were enrolled and received a series of ocular examinations. Each of our specially designed capsules contained 190 mg bromelain, 95 mg papain and 95 mg ficin. Results: In Experiment 1, 80 subjects with one SVO (symptomatic vitreous opacity, or “eye floater”) were reduced to 24 cases (30.0%; 24/80), 40 participants with multiple SVOs were decreased to 11 cases (27.5%; 11/40) three months later. In Experiment 2, the numbers of patients with SVOs in the placebo group was similar after three months. The disappeared rates of SVOs by treatment with fruit enzymes was...

    Medical XPress / University College London / Scientific Reports ^ | Nov. 24, 2021 | Professor Glen Jeffery et al
    Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a pioneering new study by UCL researchers. In summary, researchers found there was, on average, a 17% improvement in participants' color contrast vision when exposed to three minutes of 670 nanometre (long wavelength) deep red light in the morning and the effects of this single exposure lasted for at least a week. However, when the same test was conducted in the afternoon, no improvement was seen. In humans around 40 years old, cells in the eye's retina...

    SAN ANTONIO -- Face masks became seeded "almost instantaneously" with oral and nasopharyngeal bacteria, posing a potential risk of spread to the eyes during intravitreal injections for macular degeneration, according to a study reported here. Masks for all 73 patients involved in the study tested positive for a variety of common organisms, as well as some uncommon microbes. Bacteria grew on both sides of masks, irrespective of mask material age. [cut] "We didn't find a correlation between mask age and inside or outside growth, which suggests [other evidence] that even within a few hours of wearing a mask, you can...

    HEALTH bosses have confirmed they are facing an outbreak of the “eye-bleeding fever” after four people died of the suspected disease in weeks. Uganda’s health ministry has today finally admitted it is facing the risk of a large-scale explosion of the viral hemorrhagic fever (VHF). VHF causes victims to suffer a burning fever before beginning to bleed from orifices including their eyes, anuses and mouths. It comes after a girl, nine, was reportedly killed by the infection Uganda, and three people died in neighbouring South Sudan of similar symptoms. Uganda health minster Sarah Opendi confirmed emergency response teams are now...
  • Alexa has a secret new superpower: Transforming into a security camera

    05/29/2021 3:57:18 PM PDT · by algore · 25 replies
    Beneath the mild-mannered facade of a regular, everyday voice assistant, Alexa has an alter-ego -- a crime-fighter, you could say -- that can be summoned with the flip of a toggle found deep within your Amazon Echo Show's device settings. The setting is called Home Monitoring and it can transform your otherwise milquetoast smart display into a bad-guy halting security camera. (Bad guys not included.) Okay, so Home Monitoring may not be the stuff of superhero origin stories, but it's still pretty nifty as long as you don't need a lot of advanced security camera features. It doesn't record video...
  • PAUL MCCARTNEY’S SECRET TO SAVING HIS EYESIGHT

    Paul McCartney revealed the “eye yoga” he’s practiced for decades, saying it's the reason he still didn’t need glasses at the age of 78. The former Beatle said he discovered the exercises in India, where a yogi explained the reasoning to him. “He explained that your eyes are muscles whereas your ears aren’t, so you can’t exercise your ears,” McCartney noted on a recent episode of Table Manners With Jessie Ware. “But your eyes, you can.” He went on to explain how this works: “So, head still, and then you look up as far as you can – one, two,...

    MESA, AZ (3TV/CBS 5) -- Mesa police say a woman they arrested for refusing to pull over during a traffic stop told officers she did it because she "felt like it was the right thing to do." Mesa police say Hannah Clevenger was driving more than 70 miles per hour, weaving in and out of her lane, and splitting the lane line of two lanes with her car near Alma School Road and University Drive at about 2 p.m. on Tuesday afternoon. An officer pulled up behind her with his lights on. Mesa police say the officer watched as Clevenger...

    Damage to the retina is the leading cause of blindness in humans, affecting millions of people around the world. Unfortunately, the retina is one of the few tissues we humans can't grow back. Unlike us, other animals such as zebrafish are able to regenerate this tissue that's so crucial to our power of sight. We share 70 percent of our genes with these tiny little zebrafish, and scientists have just discovered some of the shared genes include the ones that grant zebrafish the ability to grow back their retinas. "Regeneration seems to be the default status, and the loss of...
  • Blue light blocking glasses: How much of the hype is science-based?

    Science Based Medicine ^ | June 25, 2020 | Scott Gavura
    There is no published evidence to demonstrate that normal environmental (including electronic) exposure to blue light damages eyesight. However it is acknowledged that eye strain can occur from staring at electronics, which can cause fatigue and headaches. Regular breaks from staring at screens (large or small) is recommended to reduce eye strain. There is some evidence that blue light from electronics can disrupt circadian rhythms, however, by suppressing the production of melatonin, a hormone that regulates our sleep. This has led electronic manufacturers to offer “night light” settings that reduce the amount of blue light displayed and give your screen’s...

    Many big cats – including lions, leopards, and tigers – are ambush predators. This means that they rely on stalking their prey and retaining the element of surprise. In some cases, being seen by their prey can lead them to abandon the hunt. We tested whether we could hack into this response to reduce livestock losses to lions and leopards in Botswana's Okavango delta region. This delta, in north-west Botswana, has permanent marshlands and seasonally flooded plains which host a wide variety of wildlife. It's a UNESCO world heritage site and parts of the delta are protected. However, though livestock...
  • Coronavirus CAN enter the body through the eyes: Scientists find eye cells are a prime target for the deadly virus to attach to

    Scientists have claimed the coronavirus can enter the body through the eyes after finding they contain a protein used by the infection to bind to cells. The coronavirus - scientifically called SARS-CoV-2 - latches onto ACE-2 receptors, known as the 'gateway' into cells inside body. These receptors are found in the respiratory tract and the lungs, which is where the virus first infiltrates cells, as well as other organs. A team led by Johns Hopkins University School of Medicine have now found the eyes produce ACE-2, making them a target for the virus. It means if droplets from an infected...

  • Chinese military taking 'irresponsible actions' toward U.S. forces in Djibouti, intel chief says

    The Chinese military is guilty of “irresponsible actions” toward American forces stationed at Djibouti’s Camp Lemonnier on the Horn of Africa, a senior U.S. military intelligence officer said. The home of U.S. military operations in the region and the biggest U.S. base on the continent, Camp Lemonnier is near the People’s Liberation Army’s first overseas military base, and the proximity has been a continuing source of tension. Rear Adm. Heidi Berg, director of intelligence at the U.S. Africa Command, told a small group of African-based journalists in a telephone media roundtable that China tried to “constrain international airspace” by barring...
  • A nanoparticle injection is all it takes to let these mice see in infrared

    By injecting specialized light-tweaking nanoparticles into a mouse’s retina, that mouse is suddenly and clearly able to perceive near-infrared light — suggesting the same could be possible for us, assuming you don’t mind a needle in the eye. The advance involves what the researchers, from the University of Science and Technology in China, call “ocular injectable photoreceptor-binding upconversion nanoparticles.” In fact, it turns out that these researchers had already created the necessary trickery for a different reason, namely as a molecule for optogenetic triggers that would absorb infrared light (which conveniently penetrates many tissues) and emit visible spectrum light instead....

Wonch-Hill, research assistant professor of sociology at the University of Nebraska-Lincoln, this week on suspicion of three counts of vandalism involving Fortenberry campaign signs and the door of Sen. Deb Fischer’s campaign office. “We are fortunate to live in a country that not only allows free speech, but also encourages open dialogue between differing perspectives,” police said in a press release. “LPD is committed to fairly and impartially protecting all citizens' right to free speech.
