​Korean scientists develop technique that detects nearly 100% of bacterial infections in under 3 hours​

/

Scientists at the Ulsan National Institute of Science & Technology (UNIST) in South Korea have made a major breakthrough in the accuracy and speed at which often deadly pathogen infections can be identified and treated. In many cases, this accelerated process can save lives. The new technique, known as fluorescence in situ hybridization (FISH), detected seven species of bacteria that commonly infect humans. It proved to be more than 99% accurate for all but one – a pathogen that infects skin tissue – which had a still-impressive 96.3% success rate.

Prostate cancer surgery breakthrough offers hope for erectile function

/

A new form of prostate cancer surgery nearly doubles the chances of men retaining erectile function, according to a new trial conducted by University College London. Known as NeuroSafe, the procedure checks tissue removed during the operation. If the tumor appears to have been removed, the nerve-containing outer layer of the prostate is left intact. The trial assessed 344 men with prostate cancer and no history of erectile dysfunction. 56% of men who had standard surgery reported severe erectile dysfunction, compared with 38% who had NeuroSafe surgery.

Paris residents vote to make 500 more streets pedestrian

/

Parisians voted to pedestrianize a further 500 of the city’s streets, giving fresh momentum to efforts by the French capital’s left-leaning town hall to curb car usage and improve air quality. The referendum will eliminate 10,000 more parking spots in Paris, adding to the 10,000 removed since 2020. The 500 additional streets to be pedestrianized will bring the total number of these so-called “green lungs” to nearly 700, just over one-tenth of the capital’s streets.

India has treated 6.8 million cancer patients for free in seven years

/

India’s Health Minister just reported that a national insurance program has treated an astonishing 6.8 million people for cancer, three-quarters of whom live in rural areas. The cost of the work amounted to $1.5 billion USD. Managed and paid for by the country’s flagship health insurance program called Ayushman Bharat, patients could get financial assistance to fight breast, oral, cervical, and lung cancers, as well as metastatic melanoma, chronic myeloid leukemia, and Burkitt’s lymphoma.

New Delhi transforms degraded lands into biodiversity parks

/

New Delhi, India’s capital city, struggles with numerous environmental challenges, including extremely poor air quality and heat waves. In response, since 2004, the city has created seven large “biodiversity parks” on previously degraded land. The Aravalli Biodiversity Park, a 692-acre park located near an upscale neighborhood, is now a thriving forest of native plants. The Neela Hauz Biodiversity Park is home to a lake that was once a dumping ground for untreated sewage. All seven parks were restored by the Delhi Development Authority and the University of Delhi and together span 2,026 acres.

Annual jab for HIV protection passes trial hurdle

/

An annual injection designed by California’s Gilead Sciences to guard against HIV has completed an important early safety trial, researchers report in The Lancet medical journal. Lenacapavir stops the virus from replicating inside cells. For the trial, 40 people without HIV were injected into the muscle with lenacapavir, with no major side effects or safety concerns. And after 56 weeks, the medicine was still detectable in their bodies. If future trials go well, it could become the longest-acting form of HIV prevention available.

U.S. approves “milestone” Parkinson’s treatment for 2025 release

/

The treatment, which will be sold under the name Onapgo, is essentially a subcutaneous – under the skin – device that allows for continuous infusion of the dopamine agonist apomorphine hydrochloride to reduce ‘off’ episodes. These episodes are periods during the day and night when lepodova medication wears off and adverse motor-function symptoms become amplified. In trial, Onapgo significantly reduced these daily off episodes by an average of 2.47 hours, compared to the placebo treatment.

U.S. FDA approves non-addictive alternative to opioids

/

The U.S. Food and Drug Administration has signed off on the first new type of pain reliever to be approved in more than two decades. The drug, suzetrigine, is a 50-milligram prescription pill that’s taken every 12 hours after a larger starter dose. Crucially, suzetrigine creates no euphoria or high like opioids sometimes can, so doctors believe there’s no potential for it to create addiction or dependence in people who use it.

New therapy trial from Australian researchers nearly doubles breast cancer cure rates

/

A phase 3 clinical trial from Melbourne’s Peter MacCallum Cancer Center has shown that adding a targeted immunotherapy drug to chemotherapy dramatically improved the cure rate for patients with the most common kind of breast cancer. In the present phase 3 trial, 510 patients were randomized to receive chemotherapy with either intravenous nivolumab or placebo. In patients treated with nivolumab plus chemotherapy, rates were statistically significant, nearly double those who received placebo plus chemo: 24.5% versus 13.8%, respectively.

Georgia certified malaria-free

/

The country of Georgia has been certified malaria-free following a nearly century-long fight to combat the disease, the World Health Organization has announced. It joins 45 countries that have achieved this milestone. Malaria has plagued Georgia since ancient times. During the post-war period, Georgia launched an intensive program focused on eliminating malaria. The campaign successfully interrupted the transmission of many strains by 1970 and the country remained malaria-free for 25 years. But by 2002 the disease had reemerged.
