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 sync.

Researchers from Aarhus University in Denmark studied the heartbeats of 37 pairs of participants as they solved four building tasks using Lego toys. The researchers then studied the heartbeats of a further 20 pairs of participants as they solved the same four building tasks, with an additional ‘trust-building’ game between each task. The researchers found that the heartbeats of these pairs sped up and were more strongly synchronised compared to the heartbeats of pairs who did not play the trust game.

“This is the first time that anyone has shown that trust between two people can be seen in heart rhythms and we have no idea why it happens,” said Panagiotis Mitkidis, co-author of the study and assistant professor at the Centre for Interacting Minds at Aarhus University.... 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? What’s the point? These are fairy tales. We are grownups, we live in the real world!” Right, so let’s look at the real world equivalent to these bothersome sounds.... 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-up studies have proved that the drug was able to reduce tumor activity by 50% after forty-one days of treatment.

Bozepinib’s powerful anti-tumorigenic properties are mainly due to the inhibition of HER-2 signaling pathways. In normal cells HER-2 protein is associated with survival, growth and proliferation. However, HER-2 is over-expressed in cancer cells, ultimately leading to a poor prognosis and decreased overall patient survival rate. This makes HER-2 one exciting target for anti-cancer therapies. The ability to target cancer stem cells is one of the aspects that makes Bozepinib a promising drug in cancer treatment.... Read more »
