Para peneliti telah memodifikasi bakteri untuk memproduksi gadusol, suatu zat pelindung sinar UV yang ditemukan pada telur ikan. Terobosan ini dapat mendukung pengembangan tabir surya yang transparan dan ramah lingkungan. Penelitian ini dipimpin oleh sebuah tim di Universitas Jiangnan di Tiongkok.

Tim yang dipimpin oleh Ping Zhang memasukkan gen dari ikan zebra ke dalam Escherichia coli. Bakteri tersebut memperoleh enzim yang diperlukan untuk menghasilkan gadusol, yang secara alami ditemukan dalam jumlah kecil pada telur ikan zebra, salmon, dan sturgeon, serta pada karang. Dengan menggunakan molekul RNA kecil dan menyesuaikan kondisi pertumbuhan, para ilmuwan meningkatkan hasil produksi hingga hampir 93 kali lipat, menjadi 4,2 gram per liter media dari sebelumnya 45,2 miligram per liter.

Researchers at the University of Kent, working with University College London, report that madecassic acid—a compound derived from the medicinal herb Centella asiatica and widely used in skincare—can inhibit the growth of antibiotic-resistant E. coli by targeting a bacterial respiratory system not found in humans or other animals.

Scientists engineer probiotic bacteria to target mouse tumors

Researchers at Shandong University have modified the probiotic bacterium Escherichia coli Nissle 1917 to produce the anticancer drug Romidepsin directly in tumors. In mouse models of breast cancer, the engineered bacteria accumulated in tumors and released the drug. The findings were published on March 17 in PLOS Biology.

Scientists identify body's natural off switch for inflammation

Researchers at University College London have discovered how the body naturally shuts down inflammation using fat-derived molecules called epoxy-oxylipins. These molecules prevent the buildup of immune cells linked to chronic diseases like arthritis and heart disease. A study involving a drug that boosts these molecules showed faster pain relief and reduced harmful immune activity.

Scientists develop lipid-coated nanopores for enhanced blue energy

Selasa, 10 Maret 2026 Dilaporkan oleh AI

Researchers at EPFL have created a new membrane using lipid-coated nanopores that boosts the efficiency of blue energy production from mixing saltwater and freshwater. The innovation allows ions to pass through more smoothly, generating up to three times more power than existing technologies. This advance could make osmotic energy a more viable renewable source.
