• A New Way to Remove Contaminants from Nuclear Wastewater

    Nuclear power continues to expand globally, propelled, in part, by the fact that it produces few greenhouse gas emissions while providing steady power output. But along with that expansion comes an increased need for dealing with the large volumes of water used for cooling these plants, which becomes contaminated with radioactive isotopes that require special long-term disposal. New method concentrates radionuclides in a small portion of a nuclear plant’s wastewater, allowing the rest to be recycled.

  • Helping Keep U.S. Nuclear Deterrent Safe from Radiation

    Advanced modeling speeds up weapons research, development and qualification. It also lets researchers model changes in experimental conditions that increase the total radiation dose, change how fast a device gets that dose, and mix and match destructive elements like neutrons, energy and heat in environments that cannot be recreated in experimental facilities.

  • Antibiotic Over-Prescribing for Kids in Poorer Nations

    A new study has found that children in eight low- and middle-income countries (LMICs) receive a remarkably high number of antibiotics by the time they reach the age of 5. The study, which looked at data on sick children who attended healthcare facilities in Haiti, Kenya, Malawi, Senegal, Namibia, Nepal, Tanzania, and Uganda over a 10-year period, found that the average number of antibiotic prescriptions written for children between birth and the age of 5 in these countries was 25.

  • The Spread and Mutation of Zika Virus

    Researchers have found that outbreaks of human disease, such as the 2015 Zika virus epidemic, may be due to genetic mutation, and viruses may undergo further changes as they expand their geographic range.

  • Seizure-Triggering Attack Is Stark Example of How Social Media Can Be Weaponized

    Followers of the Epilepsy Foundation’s Twitter handle were targeted last month with posts containing strobe light GIFs and videos which could have caused seizures for people with epilepsy, the foundation announced Monday. “While this kind of activity may not bear the hallmarks of a cyberattack, which can trick users into clicking malicious links or knock a website offline by flooding it with junk traffic, this attack shows that platforms can have even their normal functions weaponized in order to cause physical harm,” Shannon Vavra writes.

  • FDA Details Rising Sales of Antibiotics for Meat Production

    New data released by the US Food and Drug Administration (FDA) shows that the amount of medically important antibiotics sold and distributed for use in food-producing animals rose by 9 percent between 2017 and 2018, after a 3-year decline. “I’m concerned that we’re going in the wrong direction,” says one expert.

  • Lessons Learnt from Fukushima Soil Decontamination

    Following the accident at the Fukushima nuclear power plant in March 2011, the Japanese authorities decided to carry out major decontamination works in the affected area, which covers more than 9,000 km2. The European Geosciences Union (EGU) has published a collection of studies providing an overview of the decontamination strategies used and their effectiveness.

  • Switching to Renewable Energy May Save Thousands of Lives in Africa

    With economies and populations surging, an industrial revolution is inevitable on the African continent. The question is, what’s going to power it? With renewable energy cheaper and more efficient than ever, countries in Africa have the unique opportunity to harness abundant renewable sources like wind, solar and geothermal to leapfrog the dependence on fossil fuels that has poisoned the air and environment in Europe, the U.S., India and China. But will they?

  • Preparing for Chemical Attacks

    Is the U.S. ready for a chemical attack on the homeland? With the very real possibility of a chemical attack in public spaces like stadiums, religious buildings, museums and theaters, or even contamination of the food or water supply, the U.S. needs to be prepared to take appropriate action to save lives. This means having security measures in place to prevent or minimize the attack. It also means having effective medical responses that consider the quantity of medical supplies needed, transportation of those supplies to the scene, and medical facilities and personnel to care for the injured.

  • Engineered Viruses Could Fight Antibiotic Resistance

    Antibiotic resistance is a one of the world’s most pressing public health problems. Scientists working on an Army project have developed a new weapon to combat super-bugs, which could protect Soldiers and fight resistance.

  • 12 Hours. 4 Syrian Hospitals Bombed. One Culprit: Russia.

    The Bashar al-Assad regime in Syria represents the Alawite minority (in 2011, about 75 percent of the Syrian population was Sunni , and about 12 percent were Alawites). Since the civil war in Syria began in 2011, the Assad regime, in the largest ethnic cleansing campaign since the end of the Second World War, has methodically, and successfully, pursued the goal of drastically reducing the number of Sunni Muslims in Syria. So far, the Assad regime has killed more than 500,000 Syrian Sunnis; has driven more than 5.6 million Sunnis out of Syria; and internally displaced more than 6.6 million Sunnis. One of the keys to Assad’s ethnic cleansing campaign has been the systematic destruction of hospitals and medical facilities in Sunni-majority areas and the killing of medical personnel. This strategy increases the number of dead and untreated wounded among the Sunnis, and along with the methodical destruction of water and sewage treatment facilities, makes life even more unbearable in Sunni areas of Syria. Since September 2015, the Russian air force has been doing most of the destruction of medical facilities and other civilian infrastructure in Sunni-majority areas.

  • President Trump Bars Uninsured Immigrants from the U.S.

    On Oct. 4, President Trump issued a proclamation that bars otherwise qualified visa applicants from entry into the United States unless they are likely to obtain “approved health insurance” within 30 days of entry. The insurance test relies on 8 U.S.C.§ 1182(f), authorizing the president to bar entry of foreign nationals “detrimental to the interests of the United States”—the same provision that Trump used for his travel ban, which the Supreme Court upheld in Trump v. Hawaii. While the Supreme Court in Hawaii relied on the national security and foreign affairs rationale for the travel ban, the insurance test targets the very different issue of immigrants’ financial resources.

  • Close-Knit, Vaccine-Reluctant Communities Stoked Measles: CDC

    From 1 January to 1 October of this year, the United States tracked 22 measles outbreaks and 1,249 cases, according to a new overview published today by the Centers for Disease Control and Prevention (CDC) in Morbidity and Mortality Weekly Report (MMWR). “Eight outbreaks —defined as three or more related cases — that occurred in underimmunized, close-knit communities accounted for 85 percent of all cases,” the CDC said. And 75 percent of all cases in 2019 were part of outbreaks among Orthodox Jewish populations in New York State and City.

  • Funding for Research on Gun Injuries to U.S. Children Gets 30 Times Less Funding Per Death Than other causes

    Firearm injuries kill 2,500 American children each year and send another 12,000 to emergency departments. But a new study finds that the nation spends far less on studying what led to those injuries, and what might prevent and treat them, than it spends on other, less-common causes of death in children between the ages of 1 and 18 years.

  • Engineered Viruses Could Fight Drug Resistance

    In the battle against antibiotic resistance, many scientists have been trying to deploy naturally occurring viruses called bacteriophages that can infect and kill bacteria. Bacteriophages kill bacteria through different mechanisms than antibiotics, and they can target specific strains, making them an appealing option for potentially overcoming multidrug resistance. However, quickly finding and optimizing well-defined bacteriophages to use against a bacterial target is challenging. MIT biological engineers showed that they could rapidly program bacteriophages to kill different strains of E. coli by making mutations in a viral protein that binds to host cells. These engineered bacteriophages are also less likely to provoke resistance in bacteria, the researchers found.
