Ancient proteins hint at all-female Homo naledi burial site in Rising Star cave system

Scientists have extracted and analyzed the first-ever ancient proteins from the fossils of Homo naledi, revealing a potential all-female burial site. The study, published in the journal Cell, raises the possibility that South Africa's famous Rising Star Cave system could represen

Ultrafast X-rays allow researchers to 'watch' how molecules rearrange during a chemical re

Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, catalysis and light-responsive materials. But this technique, known as coherent control, has a blind spot: There has been no way to directly see the molecules in

A magnetic field that kills superconductivity can also bring it back

Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, but then unexpectedly returns when the magnetic field is

Why climate change could make staple crops less nutritious—and how CRISPR may help

At present, more than 700 million people live with caloric hunger, and more than 2 billion suffer from micronutrient deficiencies, known as "hidden hunger." By prioritizing high yield over nutritional quality, global calorie production has increased while exacerbating vitamin and

Semi-communal 'compound houses' in Ghana affect how people participate in political activi

Could the precise architectural form of your residence influence how much you participate in politics? A new study by MIT scholars finds this to be exactly the case—at least in Accra, Ghana, where many people live in semi-communal structures known as "compound houses," often shar

This single well-known and widespread butterfly is actually three species in disguise

The tropical rainforests of Central and South America are among the most biodiverse places on Earth. Costa Rica alone is home to half a million species, five times more than exist in the entire country of Canada, despite the former having 200 times less land area than the latter.

Extreme heat and health: Policy guide reveals what communities need to know

Blistering temperatures exacerbated by high humidity are not just uncomfortable but dangerous. Across Canada, and in communities throughout southwestern Ontario, rising temperatures are affecting people's health in profound and uneven ways. New research led by the University of W

What people with intersex traits want you to know

According to the Australian Bureau of Statistics, around 63,300 Australians age 16 and older—0.3% of the overall population—know they were born with variations of sex characteristics. This means their bodies don't fit medical norms about how female or male bodies should look or f

Fossil fish tooth chemistry uncovers Southern Hemisphere role in Earth's ice age shift

To understand where Earth might be headed, it's important to know where it has been. Throughout its existence, especially over the past couple of million years, Earth has experienced periodic cold and warm intervals, known as glacial and interglacial periods.

What are supermassive black holes? Everything you need to know about these mysterious obje

Nearly every massive galaxy observed hosts a supermassive black hole at its center. NASA's James Webb Space Telescope has discovered that some of these supermassive black holes may even be too big for the galaxy they're found in, challenging astronomers' understanding of these ob

Scientists measure hidden quantum forces that could power a new generation of pharmaceutic

It's one thing to design a pharmaceutical drug. It's another to know if and why it actually works; not on paper or in a computer model, but inside the chaotic world of living systems, where proteins twist into shape, atoms constantly pull and push each other apart, and molecular

Nanoparticle exsolution opens a new route to functional oxide electronics and spintronics

A research team has developed a new strategy to simultaneously control the electronic and magnetic properties of oxide thin films through a process known as exsolution. The team was led by Professor Hyeon Han and Professor Donghwa Lee from the Department of Materials Science and
