Bringing balance to the universe: New theory could explain missing 95 percent of the cosmos

Posted by in categories: cosmology, physics

Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses ‘negative mass.” If you were to push a negative mass, it would accelerate towards you. This astonishing new theory may also prove right a prediction that Einstein made 100 years ago.

Our current, widely recognised model of the Universe, called LambdaCDM, tells us nothing about what dark and dark are like physically. We only know about them because of the gravitational effects they have on other, observable matter.

This , published today in Astronomy and Astrophysics, by Dr. Jamie Farnes from the Oxford e-Research Centre, Department of Engineering Science, offers a new explanation. Dr. Farnes says: “We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of ‘negative gravity,” repelling all other material around them. Although this matter is peculiar to us, it suggests that our cosmos is symmetrical in both positive and negative qualities.”

Quantum computers put blockchain security at risk

The longer-term answer is to develop and scale up the quantum communication network and, subsequently, the quantum internet. This will take major investments from governments. However, countries will benefit from the greater security offered13. For example, Canada keeps its census data secret for 92 years, a term that only quantum cryptography can assure. Government agencies could use quantum-secured blockchain platforms to protect citizens’ personal financial and health data. Countries leading major research efforts in quantum technologies, such as China, the United States and members of the European Union, will be among the early adopters. They should invest immediately in research. Blockchains should be a case study for Europe’s Quantum Key Distribution Testbed programme, for example.


Bitcoin and other cryptocurrencies will founder unless they integrate quantum technologies, warn Aleksey K. Fedorov, Evgeniy O. Kiktenko and Alexander I. Lvovsky.

In World First, Woman Gives Birth After Receiving Uterus Transplant from Dead Donor

Posted by in categories: biotech/medical, genetics

A team of doctors in Brazil have announced a medical first that could someday help countless women unable to have children because of a damaged or absent uterus. In a case report published Tuesday in the Lancet, they claim to have successfully helped a woman give birth using a transplanted uterus from a deceased donor.

According to the report, the team performed the operation on an unnamed 32-year-old woman in a Brazilian hospital in September 2016. The woman had been born with a rare genetic condition that left her without a uterus, known as Mayer-Rokitansky-Küster-Hauser syndrome, but she was otherwise healthy. The donor was a 45-year-old woman who had suddenly died of stroke; she had had three successful pregnancies delivered vaginally in the past.
