(Georgia Institute of Technology) RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven't been very useful in treating brain tumors and other brain disease. But a team of researchers at Georgia Tech and Emory University has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery of potent medicine to brain tumors.

(Cell Press) As the pandemic persists, COVID-19 has claimed more than 200,000 lives in the United States and damaged the public health system and economy. In a study published on September 21 in the journal The Innovation, researchers at Emory University found that long-term exposure to urban air pollution may have made COVID-19 more deadly.
Depression may be among the most common mental health issues, but it is still often misunderstood. Many people assume that the condition manifests itself in really overt sorrow and hopelessness. But the symptoms tend to be much broader, and often more subtle. Including fatigue.The link between tiredness and depression is not linear and can be challenging to tease apart. But the connection is there, and mental health experts say it’s an essential one to be attuned to — perhaps more than ever during Covid-19, which has profoundly influenced people’s mental health and upended sleep routines. Here is the lowdown on depression and fatigue:Being tired is a very common symptom of depression. “Fatigue affects more than 90% of people with major depressive disorder,” said Nadine Kaslow, a professor with Emory University School of Medicine’s department of psychiatry and behavioural sciences.And fatigue does not just mean that it feels physically difficult for you to wake up in the morning (though it certainly could) or that you’re nodding off midday (though that is also a possibility).Fatigue might also manifest itself more as a general, persistent lack of energy. Even relatively simple tasks feel like they require a lot of physical and emotional effort. The relationship is complex. When it comes to depression and fatigue, “there may be an underlying ‘piece’ that is causing both,” said Betty Lai, a psychologist and assistant professor with Boston College’s Lynch School of Education and Human Development. She pointed to the possible role of the hypothalamic-pituitary-adrenal, or HPA axis, which is a system that helps regulate the body’s response to stress. “Chronic stress can disrupt the functioning of the HPA axis and lead to problems in both sleep and depression,” Lai explained.So a shared biological underpinning may be one reason for the fatigue-depression connection, but it is by no means the only one. About 80% of individuals with depression have problems sleeping — a relationship goes in both directions. Insomnia can lead to (or worsen) depression, but they can also be “overlapping” conditions. Depression itself can also lead to insomnia and sleeplessness. Also, people with underlying sleep conditions, like chronic fatigue, can also be more vulnerable to depression.“The bi-directional relationship between depression and fatigue can lead to a vicious cycle that is hard for people to break,” Kaslow explained. Another complicating factor? Medication side effects. “Treatment with medication for depression often reduces the severity of fatigue symptoms, however some medications can also cause significant fatigue,” Kaslow added. Look out for loss of interest.Mental health experts emphasise that the symptoms of fatigue that are tied to depression do not always manifest as physical tiredness. “A warning sign for depression is: ‘Oh, I used to like to do this ... I used to like to do this activity or engage in social situations. But I don’t want to do it. I’m not motivated,’” said Tameka Brewington, a psychotherapist and owner of Real Talk Counseling. So when diagnosing depression, mental health professionals are really on the lookout for a kind of emotional fatigue and loss of motivation.If someone feels motivated to participate in their usual activities but is simply too tired, Brewington said, they’ll focus more on discovering the root causes of their fatigue. Covid-19 may be complicating things even more. Again, the available evidence suggests that the pandemic is taking a toll on people’s mental health. A recent survey by the Centers for Disease Control and Prevention, for example, found that 30% of Americans were recently grappling with symptoms of depression or anxiety. One in four parents said their mental health has worsened during the pandemic, and one in seven said that’s true of their kids. At the same time, disruptions to normal routines and the stress of living in a pandemic with an unknown, drawn-out timeline can — and has — taken a toll on sleep.So experts say it is particularly important to pay attention to prolonged changes in emotional health, sleep patterns and fatigue. Particularly if they last for more than two weeks, Brewington said. “Everyone should have an awareness that they could be anxious or depressed, or recognise that they have fatigue, because of the fact that we are living in a pandemic and dealing with Covid,” she said. The fact that fatigue is sometimes easier to talk about is a good thing. “Sleep can be easier for people to talk about — and notice,” Lai said. So it can be a nice “entry point” for people who might otherwise struggle to connect with mental health support, she explained.Because unfortunately, the stigma around seeking mental health support persists. Data shows that more than 30% of people say they’ve worried other people are going to judge them for getting mental health care, and up to 50% of teens and young adults say that’s the case. All of the mental health experts interviewed for this story repeated just how crucial it is for anyone concerned about depression, fatigue or both to seek help. There are many effective treatments for depression, from talk therapy and support groups to medication.You might want to start by looking into different types of therapists and different approaches to therapy, and by checking resources like Psychology Today, Therapy for Black Girls or Good Therapy. There are also ways to find more affordable therapy options if you’re unable to swing the cost of appointments (which is a struggle for many, many people). Also, one upside of the Covid-19 pandemic is that it’s easier than ever to begin virtual therapy. Ultimately, doctors and mental health providers can also determine — and address — the root causes of persistent fatigue. “This is real,” Brewington said. “It won’t just go away on its own.”Related...

US tech giant Oracle is reportedly preparing a bid for the US operations of massively popular social media app TikTok.
President Trump, expressing support for Oracle's bid, called it a "great company."
Larry Ellison, the Oracle cofounder, is one of the richest people in the world and has previously hosted a fundraiser for Trump at his Coachella Valley home (he told Forbes he didn't attend).
Representatives for Oracle declined to comment for this story. The Trump campaign did not immediately respond to request for comment.
Take a look inside their relationship.

Oracle is reportedly eyeing a bid to take over popular social media app TikTok — with President Trump's support.
On August 14, President Trump released an executive order directing ByteDance, TikTok's parent company, to sell all of its US operations in the next 90 days and distance itself from any data collected through the popular app, citing a potential threat "to impair the national security of the United States."
Prior to that, he signed a different executive order on August 6 that would prevent China-based companies, like TikTok, from doing business in the US. Trump began discussing similar actions regarding TikTok in late July, when he told reporters onboard Air Force One: "As far as TikTok is concerned, we're banning them from the United States."
Microsoft was the first major US tech firm to confirm, in an early August blog post, that it was considering acquiring TikTok's American assets. CNBC reported that it could go for as high as $30 billion.
Earlier this week, the New York Times, Axios, Guardian, and others reported that Oracle is preparing a rival bid for TikTok's US operations.
On August 19, President Trump said that Oracle is a "great company" and, regarding a TikTok takeover, said it "would be certainly somebody that could handle it."
Ellison stepped down as Oracle CEO in 2014 but continues to enjoy his position as one of the richest people in the world.
Ellison, ranked ninth in the list of richest people in the US and twelfth in the world, has a net worth of $64.6 billion. The number grew by just a hair short of $6 billion in the last year. His Bloomberg Billionaires profile credits him as being "self-made."
In 1977, Ellison and two colleagues at an electronic company cofounded the programming firm that evolved into Oracle Corp. Ellison stepped down as CEO in 2014 but remained at the company as executive chairman of the board and chief technology officer.
He bought the Hawaiian Island of Lanai for $300 million in 2012, which Forbes later called "his petri dish of experimentation on health, wellness, and sustainability." During the coronavirus pandemic and shutdown, Ellison said he would pay his workers full wages and benefits through at least May 1.
He currently lives in Rancho Mirage in California's Coachella Valley.
In a Forbes profile from April 2020, Ellison said he supports Trump and wants him to do well.
"We only have one president at a time. I don't think he's the devil — I support him and want him to do well," Ellison told Forbes writer Angela Au-Yeng. He added that he would support anyone who's currently in the Oval Office.
Ellison also told the magazine that he had never donated to the Trump campaign. The Desert Sun reported that Ellison didn't donate in 2016 or 2020, citing federal campaign reports.
Ellison held a fundraiser for Trump at his Rancho Mirage home in February, with the contributions going to a fundraising committee created in collaboration between his campaign and the state and national chapters of the Republican Party.
The Desert Sun's Sam Metz reported that Ellison's Rancho Mirage property hosted supporters of the president's reelection bid on a golf outing.
A $100,000 donation guaranteed golf with the president and a photo to commemorate the occasion. With $250,000, supporters got everything in the previous bracket as well as a round-table conversation.
As for whether he was present during the fundraiser, Ellison told Forbes, "Be absolutely precise. I said President Trump could use the property. I was not here."
Barack Obama visited the same golf course in 2015. Theodore Schleifer wrote for Recode that Ellison was previously known to be close to Bill Clinton and attended fundraisers for his reelection in the '90s.
Though Ellison has maintained that he wasn't physically present at the fundraiser, his hosting didn't sit well with some of his employees.
After news broke that Ellison was hosting the fundraiser, a Change.org petition started circulating online, asking senior Oracle leadership to condemn Ellison's actions. The petition gathered close to 10,000 signatures.
The day after the fundraiser, about 300 Oracle employees staged a walkout called "No Ethics / No Work."
Nico Grant reported for Bloomberg that employees stopped working at noon local time, wherever they were located, and devoted the rest of the day to volunteer work.
Per Forbes, Ellison and Trump had a phone call in the initial days of the coronavirus pandemic in the US. It is unclear who called whom.
The New York Times reported in April that Ellison was the first person Trump heard from about hydroxychloroquine and chloroquine as possible treatments for the novel coronavirus.
The president has repeatedly touted the two anti-malaria drugs, even saying that he's taken one of them himself, despite scientists and doctors warning against it.
In June, the Food and Drug Administration revoked approval for emergency use of the two drugs, citing their lack of effectiveness and warning they could have potentially "serious side effects."
Dr. Carlos Del Rio, an infectious disease physician at Emory University School of Medicine at Emory University, told NBC News in July that "it does not work for treatment or for prevention. I have no idea why there is still talk about it, but it's wrong."
Ellison brought together engineers at his own company and federal agencies to create a far-reaching coronavirus database.
Per his April Forbes profile, Ellison brought together Oracle engineers and officials from federal agencies including the FDA and the National Institutes of Health to build a database of COVID-19 cases in the US where doctors could log treatments used and their effectiveness.
The Washington Post reported that, among other drugs, hydroxychloroquine and chloroquine were being tested through this system.
Trump put Ellison on the tech cohort of his Great American Economic Revival Industry Groups.
In April, Ellison joined industry bigwigs such as Mark Zuckerberg, Tim Cook, and Satya Nadella on a tech committee to advise President Trump on how to safely reopen the economy.
In February, the Trump administration argued before the Supreme Court that Microsoft's decade-long legal case against Oracle be dismissed. This recommendation came on the same day as Trump's fundraiser at Ellison's Coachella Valley home.
The lawsuit has been in the court system for a decade and began when Oracle sued Microsoft for use of copyrighted programming in Android devices. The Trump administration asked the Supreme Court to disregard Microsoft's appeal.
Bloomberg reported that this would potentially allow Oracle to collect $8 billion in royalties.
Ellison isn't the only top Oracle employee to show President Trump support. In 2016, co-CEO Safra Catz joined the transition team.
While maintaining her position at the tech company, Safra Catz joined the president-elect's transition team in December 2016.
An executive who had been at Oracle on and off for longer than two decades resigned soon after in response.
We’re here to guide you through the coronavirus pandemic. Sign up to the Life newsletter for daily tips, advice, how-tos and escapism.As fellow Brits pile on planes headed for tropical destinations, many of you will be wondering whether you, too, should book a last-minute summer getaway. One of the things that might be holding you back – in addition to the prospect of quarantine on return – is getting on a plane. Being contained on an airtight vessel with strangers (and their germs) for hours doesn’t sound like the most ‘Covid secure’ environment. Historically, studies have found planes can be breeding grounds for infectious diseases – add into the mix the prospect of a potentially airborne illness and it doesn’t fill a person with hope. So, is the air safe on a plane?Professor Qingyan Chen, an expert in mechanical engineering at Purdue University, tells HuffPost UK while coronavirus could be airborne – and therefore may spread through air conditioning systems – “the virus concentration in air is very low”. But if you’re exposed to a low virus concentration in the air for a long time, there’s a higher risk of becoming infected. Related...
6 Things To Consider Before Booking A Holiday In 2020
Generally it’s believed the filters used on aircrafts, called high efficiency particulate air (HEPA) filters, do a good job of filtering out particles the size of Covid-19.“The interesting thing is there haven’t been documented cases of transmission on airlines,” says Professor David Hunter, an expert in epidemiology in the Nuffield Department of Population Health at University of Oxford. “My guess is that’s probably because most of the airlines... have been flying mostly empty.”While flying isn’t without its risks, Prof Hunter says right now, the destination is likely to be more risky anyway. “If someone’s travelling, depending on where they’re travelling to, they’re probably at greater risk of picking up the virus when they spend a couple of weeks in the other destination, than they are to get it on the plane.”The Foreign & Commonwealth Office currently advises Brits against all but essential international travel – but travel to some countries is exempt from this advice, including France, Croatia and Italy. When travelling on a plane during the pandemic, people are advised to: remain seated as much as possible; follow instructions and guidance from crew; use contactless payment where possible; be aware there’s likely to be a reduced food and drink service; and make the cabin crew aware if you become ill.

There are other things you can do to reduce your risk of catching the virus on a flight. Opt for a shorter flightProfessor Hunter says one of the key factors to consider is how long you’re flying for. Shorter flights – for example, a one-hour flight – pose less of a risk than, say, a four-hour flight.Fly at quieter times, if you canIf there are hardly any people on your flight, the risk is automatically lowered as there are fewer people to catch the virus from. You might want to discuss quieter times with the airline before booking – although nothing can be guaranteed.“I wouldn’t want to be on a plane that’s choc-a-block,” says Prof Hunter. “I’d feel relatively safe on a plane where they’re flying three quarters empty and they’ve spaced people out.” Sit at a distance from othersWhere you’re seated – and how far away you’re sat from others – is important. If people are spread out, it would be safer than if you have to sit right next to, or directly in front of, someone.A FlyHealthy study conducted by researchers from Emory University in 2018 found an infectious passenger with influenza was unlikely to transmit infection to passengers seated further away than two seats laterally and one row in front or behind. If you’re seated close to someone, ask if you can move.A preprint study about Covid-19 transmission on planes suggested when all seats are full on a US jet aircraft, the risk of contracting Covid-19 from a nearby passenger is about 1 in 7,000. But if the middle seat is left empty, that risk falls to about 1 in 14,000. Related...

Keep your hands clean and don’t touch your faceThe same study about Covid-19 transmission discovered another key mode of transmission was touching infected surfaces such as tray tables, seat belts and lavatory handles. This is one of the primary ways to catch Covid-19.“Passengers and flight crews can eliminate this risk of indirect transmission by exercising hand hygiene and keeping their hands away from their nose and eyes,” the researchers suggested. The same rules apply now, keep those mitts clean (hand sanitiser is your friend on flights) and do not touch your face.It might be worth taking some cleaning wipes with you to wipe down the seatbelt, armrests and tray tables.Wear a face cover“To protect from infection, it’s important that everyone wears masks,” says Prof Chen. Different airlines have different measures in place surrounding mandatory face coverings, although most will require you to wear one. If everyone wore a mask, theoretically, that means fewer droplets will escape from people’s noses and mouths into the environment – and there will be less of a temptation to touch your face.Government advice states you can remove your face covering to: communicate with someone who relies on lip reading; avoid harm or injury; take medication and eat or drink (if reasonably necessary).Related...

A new experimental treatment was able to rapidly reduce the flu virus in ferrets, but human trials are still a ways off.Researchers at Georgia State and Emory University in the US have spent the last few years trying to develop what they’ve billed as next-generation antivirals.One lead they’ve followed is a molecule that can attack and inhibit a wide variety of RNA viruses – including chikungunya, Zika, and influenza – called N4-hydroxycytidine (NHC).In animal experiments, at least, NHC seems to throw a big wrench into how an RNA virus replicates itself, leading to disastrous, fatal mutations.So the researchers created different experimental drug candidates based on NHC that seem to get over this hurdle.And it’s one of these candidates, called EIDD-2801, that was tested out in ferrets for the new study, published today in Science Translational Medicine.
Psychologists at Emory University have found that the human brain uses three distinct systems to perceive our environment -- one for recognizing a place, another for navigating through that place and a third for navigating from one place to another.For a new paper, they designed experiments involving a simulated town and functional magnetic resonance imaging (fMRI) to gain new insights into such systems.Their results, published by the Proceedings of the National Academy of Sciences (PNAS), have implications ranging from more precise guidance for surgeons who operate on the brain to better computer vision systems for self-driving cars."The PNAS paper provides the last big piece in the puzzle."The experiments showed that the brain's parahippocampal place area is involved in recognizing a particular kind of place in the virtual town, while the brain's retrosplenial complex is involved in mentally mapping the locations of particular places in the town.These new results follow work published last year by the Emory researchers, showing that the brain's occipital place area is involved in navigating through a particular place.
A chameleon can alter the color of its skin so it either blends into the background to hide or stands out to defend its territory and attract a mate.The chameleon makes this trick look easy, using photonic crystals in its skin.Scientists, however, have struggled to make a photonic crystal "smart skin" that changes color in response to the environment, without also changing in size."We've developed a new concept for a color-changing smart skin, based on observations of how nature does it.""Scientists in the field of photonic crystals have been working for a long time to try to create color-changing smart skins for a range of potential applications, such as camouflage, chemical sensing and anti-counterfeiting tags, " adds Khalid Salaita, senior author of the paper and an Emory professor of chemistry.Co-authors of the paper include Alisina Bazrafshan and Dale Combs (Emory PhD students); Kimberly Clarke (an Emory post-doctoral fellow); and Anastassia Pokutta, Fatiesa Sulejmani and Wei Sun (from Georgia Tech's Wallace H. Coulter Department of Biomedical Engineering).
A wireless sensor small enough to be implanted in the blood vessels of the human brain could help clinicians evaluate the healing of aneurysms -- bulges that can cause death or serious injury if they burst.To reduce costs and accelerate manufacturing, fabrication of the stretchable sensors uses aerosol jet 3D printing to create conductive silver traces on elastomeric substrates.The 3D additive manufacturing technique allows production of very small electronic features in a single step, without using traditional multi-step lithography processes in a cleanroom."The beauty of our sensor is that it can be seamlessly integrated onto existing medical stents or flow diverters that clinicians are already using to treat aneurysms," said Woon-Hong Yeo, an assistant professor in Georgia Tech's George W. Woodruff School of Mechanical Engineering and the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University.Inserted using a catheter system, the sensor would use inductive coupling of signals to allow wireless detection of biomimetic cerebral aneurysm hemodynamics.Because of the cost and potential negative effects, use of the imaging technique must be limited.
