Cell therapy that repairs cornea damage with patient's own stem cells achieves positive phase I trial results

Novel stem cell therapy called a CALEC transplant was performed safely in four patients with serious chemical burns tracked in a phase I clinical trial for 12 months. The patients experienced early clinical gains: two were able to undergo a corneal transplant and two reported significant improvements in vision without additional treatment. CALEC procedure takes small amount of stem cells from healthy eye, grows and expands stem cells on a graft, before it is transplanted into the patient's damaged eye.

Optical Illusion: क्या 7 सेकेंड्स में ढूंढ सकते हैं तस्वीर में छिपा दिल?

Optical Illusion नजर और दिमाग के बीच तालमेल बिठाना चाहते हैं तो उसके लिए ऑप्टिकल इल्यूजन एक मजेदार तरीका है। यह आपकी क्षमता को जांचने में भी मदद करता है। इसे सॉल्व करते हुए माइंड क्रिएटिव और शार्प बनता है। ऐसे में हर रोज इसे सॉल्व करने से दिमाग की नई-नई चीजें सोचने की क्षमता बढ़ती है। आइये देखते हैं कि आज के ऑप्टिकल इल्यूजन चैलेंज में क्या है।

Anti-obesity drug improves associative learning in people with obesity

Obesity leads to altered energy metabolism and reduced insulin sensitivity of cells. The so-called 'anti-obesity drugs' are increasingly used to treat obesity and have caused tremendous interest, especially in the USA. Researchers have now shown in people with obesity that reduced insulin sensitivity affects learning of sensory associations. A single dose of the anti-obesity drug liraglutide was able to normalize these changes and restore the underlying brain circuit function.

Novel treatment based on gene editing safely and effectively removes HIV-like virus from genomes of non-human primates

A single injection of a novel CRISPR gene-editing treatment safely and efficiently removes SIV -- a virus related to the AIDS-causing agent HIV -- from the genomes of non-human primates, scientists now report. The groundbreaking work complements previous experiments as the basis for the first-ever clinical trial of an HIV gene-editing technology in human patients, which was authorized by the Food and Drug Administration (FDA) in 2022.

Platelets can replicate the benefits of exercise in the brain

Researchers have found an injection of a specific blood factor can replicate the benefits of exercise in the brain. They've discovered that platelets secrete a protein, exerkine CXCL4/Platelet factor 4 or PF4, that rejuvenates neurons in aged mice in a similar way to physical exercise. This protein, which is released from platelets after exercise, results in regenerative and cognitive improvements when injected into aged mice.

New type of star gives clues to mysterious origin of magnetars

Magnetars are the strongest magnets in the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers don't know exactly how they form. Now, using multiple telescopes around the world, researchers have uncovered a living star that is likely to become a magnetar. This finding marks the discovery of a new type of astronomical object -- massive magnetic helium stars -- and sheds light on the origin of magnetars.

Adherence to a Mediterranean lifestyle associated with lower risk of all-cause and cancer mortality

People who adhere to a Mediterranean lifestyle -- which includes a diet rich in fruits, vegetables, and whole grains; healthy eating habits like limiting added salts and sugars; and habits promoting adequate rest, physical activity, and socialization -- have a lower risk of all-cause and cancer mortality, according to a new study. People who adhered to the lifestyle's emphasis on rest, exercise, and socializing with friends had a lower risk of cardiovascular disease mortality.

Scientists trap light inside a magnet

A new study shows that trapping light inside magnetic materials may dramatically enhance their intrinsic properties. Strong optical responses of magnets are important for the development of magnetic lasers and magneto-optical memory devices, as well as for emerging quantum transduction applications.
