Over 200 molecules have been discovered in space, some (like Buckminsterfullerene) very complex with carbon atoms. Besides being intrinsically interesting, these molecules radiate away heat, helping giant clouds of interstellar material cool and contract to form new stars. Moreover, astronomers use the radiation from these molecules to study the local conditions, for example, as planets form in disks around young stars.

Non-Invasive Strategy Delivers Nanoparticles to the Brain
Brain stimulation paired with a nose spray comprised of nanoparticles can increase recovery after ischemic stroke in an animal model, according to scientists from Xi’an Jiaotong-Liverpool University and other universities in China. The nasal spray is [...]
The race to fight the ‘superbugs’ – the next global health threat
Increasing drug resistance could leave us powerless to fight infections we now consider routine, and scientists are urgently searching for answers. It was just a urinary tract infection (UTI). Helen Osment, a fundraiser from Hertfordshire, had [...]
A mass production method for biodegradable microrobots
Daegu Gyeongbuk Institute of Science & Technology (DGIST, President Yang Kook) Professor Hongsoo Choi’s team of the Department of Robotics and Mechatronics Engineering collaborated with Professor Sung-Won Kim’s team at Seoul St. Mary’s Hospital, [...]
DNA nets capture COVID-19 virus in low-cost rapid-testing platform
Tiny nets woven from DNA strands can ensnare the spike protein of the virus that causes COVID-19, lighting up the virus for a fast-yet-sensitive diagnostic test—and also impeding the virus from infecting cells, opening [...]
Dissolvable Optical Switches Control Neurons With Light
Roughly two decades ago, a strategy called optogenetics emerged to control brain activity with lasers. It uses viruses to insert genes into cells that make them sensitive to light. Optogenetics has revolutionized neuroscience by giving researchers [...]
Single Dose Nanovaccine Developed to Help Tackle Shigella
Shigella bacteria, which causes Shigellosis, is the primary cause of bacterial diarrhea and diarrheal death among juveniles under five years of age. Because of the antibiotic resistance of Shigella strains, no commercial vaccines are available to date. [...]
Tiny robots with ‘brains’ can walk autonomously inside your body
Scientists have built microscopic robots equipped with electronic “brains” that are capable of walking autonomously. A team from Cornell University in the US developed the solar-powered bots as part of research into a new generation of [...]
Long COVID patients show signs of autoimmune disease a year after infection
Blood samples from patients with long COVID who are still suffering from fatigue and shortness of breath after a year show signs of autoimmune disease, according to a study published today (Thursday) [...]
Inhibiting Ovarian Cancer Growth Using Gold Nanoparticles
High-grade serous ovarian cancer (HGSOC) is among the deadliest human cancers and its prognosis remains extremely poor. An article published in Advanced Science explored the self-therapeutic properties of gold nanoparticles to identify a molecular axis that [...]
New Strategy To Help Chitosan Nanocrystals Target Cells
Antimicrobial peptides (AMPs) have a broad spectrum of antimicrobial activity and lyse microbial cells by interaction with biomembranes, offering great potential in designing new therapeutics. The antimicrobial resistance (AMR) caused due to overuse of [...]
Drug turns cancer gene into ‘eat me’ flag for immune system
Tumor cells are notoriously good at evading the human immune system; they put up physical walls, wear disguises and handcuff the immune system with molecular tricks. Now, UC San Francisco researchers have developed a [...]
New Adjustments to Hyperspectral Microscopy of Nanomaterials
Hyperspectral microscopy is an advanced visualization technique that combines hyperspectral imaging with state-of-the-art optics and computer software to enable rapid identification of nanomaterials. Since hyperspectral datacubes are large, their acquisition is complicated and time-consuming. [...]
Nanoplatforms in Imaging-Guided Brain Tumor Treatment
Malignant brain tumors are cancerous growth in the brain with the possibility of spreading to other parts of the central nervous system (CNS). Brain tumors are highly invasive and have devastating consequences, poor prognosis, [...]
