Researchers have been working to develop and optimise suitable bioinks for additive manufacturing, in the hope that we will soon be using 3D-printed biologically functional tissue to replace irreparably damaged tissue in the body. [ + ]

Researchers in South Korea and Singapore have developed a chemical probe that enables live imaging of a type of immune cells in the brain, known as microglia, in a live animal brain. [ + ]

Oral vaccines are both safer and less expensive than injections, so researchers are continuously pursuing ways to produce an oral vaccine that is sufficiently effective. [ + ]

A newly named tyrannosauroid dinosaur — Suskityrannus hazelae — stood less than a metre tall at the hip and was about 2.7 metres in length. [ + ]

Most will associate cancer with its fast growing cells that spread uncontrollably — but in fact, it's often the cancer cells that are dormant and inactive that pose the greatest threat. [ + ]

Researchers have shown that suppressive antiretroviral therapy (ART) for HIV reduces the virus load down to undetectable levels, meaning the virus is no longer transmissible. [ + ]

A new colorectal cancer vaccine, developed by US researchers, has shown positive results in a phase I clinical trial to demonstrate that the approach is safe. [ + ]

Astronomers have discovered rapidly swinging jets coming from a black hole almost 8000 light-years from Earth — behaviour that has never before been observed on such short timescales. [ + ]

How critical is quick thawing when working with mammalian cells, such as T cells used for cellular therapies? [ + ]

Despite effectively inducing desensitisation in the clinic, oral immunotherapy for peanut allergies appears to considerably increase allergic and anaphylactic reactions. [ + ]

Scientists have shown how pancreatic stellate cells become activated and secrete proteins to form a shell around the tumour in an attempt to wall off and contain it. [ + ]

Known as RTS,S, the vaccine will be made available first in Malawi, for access to children up to two years of age. Ghana and Kenya will introduce the vaccine in the coming weeks. [ + ]

Results from NASA's landmark Twins Study, which studied one twin in spaceflight and one on the ground, have finally been published. [ + ]

US researchers have discovered how mosquitoes pick up on acidic volatiles found in human sweat. [ + ]

The method may provide a more accurate snapshot of rearranged DNA found in cancer, and could help connect cancer patients with personalised treatments faster than current methods. [ + ]
