Black Holes Can Over-Eat, Too.

by Jeffrey Daniels in United Academics

Once upon a time, it was thought that black holes could ‘eat-up’ accreted matter. That is: gas, dust, and other such things that have been pulled into the black hole’s gravity field, usually forming a disk of rotating material. The black holes would pull the matter into infinity, with no limit to how large a black hole could become in this manner.... Read more »

Trust Issues? Listen To Your Heart

by Kate Blanchfield in United Academics

Research shows that our hearts beat in sync when we think about trusting each other.

trust, heart, heartbeat, synchronisation, public goods game

Trust is a crucial part of society, building complicated links between individuals, companies and even nations, but behavioural scientists have struggled to find a way to measure the physiological signs of trust. A new study suggests that our hearts might hold a clue: the heart rates of people who think about trusting one another start to beat in ........ Read more »

Pinocchio and Captain Hook: Suffering from Tinnitus?

by Chiara Civardi in United Academics

You might be wondering what Pinocchio and Captain Hook have in common. Well, they are both from children’s stories, they both have prosthetics, they have issues with being honest, and they both experience interesting maritime adventures. But there is something else too: they are both annoyed by a continuous ticking sound that follows them everywhere. For Pinocchio it is Jiminy Cricket who bothers him while for Hook the crocodile is ticking merrily away. I can hear you saying: “So? Wh........ Read more »

A New Boost for Cancer Stem Cell Therapies

by Rita dos Santos Silva in United Academics

Patent for Bozepinib approved by scientists of University of Granada

Researchers at the University of Granada, Spain, have patented Bozepinib, a drug that inhibits the growth of cancer stem cells in breast, colon and melanoma cancers.

The mechanisms of action of Bozepinib were first described in an article published in the Open Access journal Oncotarget back in 2014. The team showed that Bozepinib was able to inhibit growth and metastasis of tumors in mice without inducing toxicity. Follow........ Read more »

Death Will Come and Will Have Your Eyes

by Chiara Civardi in United Academics

Once upon a time there was a high school student who was struggling to write a literature essay. The student couldn’t find anything good about the writer she had to discuss; he simply looked like a depressed misogynist, unable to even properly commit suicide at the first try. There is no need to write and publish a poem called “Death Will Come and Will Have Your Eyes” just because a woman broke up with you (not that the student would blame her), right?

The student grew up, f........ Read more »
