Gold- and bronze-like paints that don't contain metal
Lustrous metallic paints are used to enhance the beauty of many products, such as home decorations, cars and artwork. But most of these pigments owe their sheen to flakes of aluminum, copper, zinc or other metals, which have drawbacks. Now, researchers have developed organic-only dyes that can form films resembling gold or bronze, without the need for metals.

More diversity needed in oil palm plantations
Growing global demand for palm oil has led to a rapid spread of oil palm monoculture plantations in South East Asia, often associated with the loss of habitats and biodiversity. Plantations are uniformly structured, offering little space for different species. Diversification using indigenous tree species can help. Researchers found diversification can be encouraged through information campaigns a

New study suggests crucial role for lymphocytes in asymptomatic COVID-19 infection
A retrospective study of 52 COVID-19 patients may help researchers better understand why not everyone show symptoms of the disease. The study's authors found that asymptomatic patients hosted viral loads comparable to those of symptomatic patients, but asymptomatic patients showed higher levels of lymphocytes (a type of white blood cell responsible for immune responses), cleared the viral particle

Making heads or tails out of phospholipid synthesis
Most scientists agree that life on Earth began about 4 billion years ago, but they don't agree where—on land or in water. They know that about 2 billion years ago, single-celled organisms evolved into complex plants and animals whose membrane-bound cells had a nucleus and separate compartments, called organelles, with specific functions. This marked an important moment in cellular evolution.

New eclipsing double white dwarf binary discovered
Astronomers from the California Institute of Technology and elsewhere report the detection of a new eclipsing detached double white dwarf binary. The system, designated ZTF J2243+5242 has an orbital period of below 10 minutes, which makes it one of the shortest-period eclipsing binaries known to date. The finding is detailed in a paper published October 7 on arXiv.org.

Scientists: That "99.9% Dark Matter" Galaxy Is Actually Perfectly Normal
Cosmic Puzzle A few years ago, scientists discovered an extremely puzzling galaxy that appeared to contain 10,000 times more dark matter than visible matter.
