Cambridge scientists might have possibly detected presence of dark energy.

About a year ago, the XENON1T experiment reported an unexpected signal, or excess, over the expected background. “These sorts of excesses are often flukes, but once in a while they can also lead to fundamental discoveries,” said co-author Dr Luca Visinelli.

It’s curious to read about the scientists talking about their experiments. Their palpable excitement is always contagious.
