Beiersdorf is one of the most advanced skincare companies in the world. The company has been using artificial intelligence, in partnership with Insilico Medicine, to improve its range of skincare products.

Complete human genome extracted from 6,000 year-old gum

Chewing gum is never easy to get rid of, and one piece of gum, estimated to be 5,700 years-old, has enabled scientists to map out the human genome of the person who chewed it and to gain an insight into their microbiome.

Essential Science: The top science stories of 2019

Digital Journal provides cutting-edge science and technology features throughout the year. We present the pick of 2019, showcasing the latest innovative research, from stormquakes to bioprinting human hearts.

New insight into how DNA holds together revealed

It has been long thought that DNA, the hereditary material in most organisms, binds itself due to hydrogen bonds. However, new research shows this is not the case and instead water is key to keeping the structure together.

Australian men live longer than any other group of males

New data analysis reveals that Australian men are now living longer than any other group of males in the world. The data has been normalized for historical mortality conditions.

Decoding the mysteries of da Vinci's paintings with proteomics

Scientists have used the technique of proteomics to assess the paint blends used in a painting supervised by Leonardo da Vinci. The exercise paves the way for improving the restoration and validation of older paintings.

Washington - There might be life on the Moon after all: thousands of virtually indestructible creatures that can withstand extreme radiation, sizzling heat, the coldest temperatures of the universe, and decades without food.

Japan set to undertake human-animal embryo experiments

Japan has approved the first ever human-animal embryo experiments. This research could produce an alternative sources of organs for transplant. However, there are an array of ethical and technical hurdles to be addressed.

Crocs were once vegetarians, but it was just a phase

Washington - Crocodiles are sometimes described as living fossils for their close resemblance to their forebears who roamed the Earth during the age of the dinosaurs.

New cause of autism: Unwanted DNA?

Scientists have suggested that a new cause of autism could be found in 'junk' DNA. This relates the neurodevelopmental condition to mutations in the non-coding regions of the human genome, according to the new study.

Northwestern-UIUC researchers launch Illinois’ new twins registry

Northwestern-UIUC scientists have created the Illinois Twins Project (ITP). This is designed to be the first- database to function as scientific resource for scientists exploring how genes and environment influence twins and multiples.
