First fossil nursery of the great white shark discovered
First fossil nursery of the great white shark discovered
Paleo-kindergarten ensured evolutionary success millions of years ago An international research team led by Jaime A. VillafaŮa from the Institute of Palaeontology at the University of Vienna discovered the first fossil nursery area of the great white shark, Carcharodon carcharias in Chile. This discovery provides a better understanding of the evolutionary success of the largest top predator in today's oceans in the past and could contribute to the protection of these endangered animals.

Bumblebees speed up flowering
Bumblebees speed up flowering
When pollen is in short supply, bumblebees damage plant leaves in a way that accelerates flower production, as an ETH research team headed up by Consuelo De Moraes and Mark Mescher has demonstrated. Spring has sprung earlier than ever before this year, accompanied by temperatures more typical of early summertime.

Using satellites and AI to help fight poverty in Africa
A new tool combines publicly accessible satellite imagery with AI to track poverty across African villages over time. In combating poverty, like any fight, it's good to know the locations of your targets. That's why Stanford scholars Marshall Burke , David Lobell and Stefano Ermon have spent the past five years leading a team of researchers to home in on an efficient way to find and track impoverished zones across Africa.

Past is prologue: Genetic 'memory' of ancestral environments helps organisms readapt
Past is prologue: Genetic ’memory’ of ancestral environments helps organisms readapt
Organisms carry long-term "memories” of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site. The study provides new insights into how creatures adapt to changing environments, a topic that's especially relevant today in the context of rapid climate change, which is creating challenges for plants and animals worldwide.

Solar energy farms could offer second life for electric vehicle batteries
Modeling study shows battery reuse systems could be profitable for both electric vehicle companies and grid-scale solar operations. As electric vehicles rapidly grow in popularity worldwide, there will soon be a wave of used batteries whose performance is no longer sufficient for vehicles that need reliable acceleration and range.

Google search data reveals American’s concerns about abortion
Women demonstrate in favor of expanded birth control access in front of the Supreme Court on a snowy day in March 2014. A new study of Google search data reveals that limiting access to contraception makes people more likely to search for abortion information online. (AP photo by Charles Dharapak) Residents of states with limited access to contraceptives and high rates of unplanned pregnancies are more likely to turn to the internet for information about abortion.

Potential US COVID-19 resurgence modelled as lockdowns ease
Potential US COVID-19 resurgence modelled as lockdowns ease
Increased mobility in the United States as lockdown measures lift could result in a surge of coronavirus infections and deaths. While the US had an initial 2.2 national average R reproduction number earlier in the outbreak, 24 states still have a reproduction number above the critical threshold of one, Imperial modellers have found.

New gravitational-wave model can bring neutron stars into even sharper focus
Gravitational-wave researchers at the University of Birmingham have developed a new model that promises to yield fresh insights into the structure and composition of neutron stars. The model shows that vibrations, or oscillations, inside the stars can be directly measured from the gravitational-wave signal alone.

Researchers Solve Structure of Crucial Cellular Component
All human cells are enclosed in a greasy membrane that is embedded with thousands of different proteins. These so-called membrane proteins carry out countless functions, from regulating our blood pressure, to coordinating our immune responses, to controlling the firing of neurons in our brains. Membrane proteins are so important that they are targeted and regulated by more than half of all pharmaceutical drugs on the market today.

Chemical recycling makes useful product from waste bioplastic
A faster, more efficient way of recycling plant-based “bioplastics” has been developed by a team of scientists at the Universities of Birmingham and Bath. The team has shown how their chemical recycling method not only speeds up the process, it can also be converted into a new product - a biodegradable solvent - which can be sold for use in a wide variety of industries including cosmetics and pharmaceuticals.

Oxford leads on UK trial sites testing potential COVID-19 preventatives
The Diabetes Trial Unit (DTU) in the Radcliffe Department of Medicine is managing the UK sites for a global study testing if either chloroquine or hydroxychloroquine can prevent COVID-19 in vital frontline healthcare workers. Laboratory evidence shows that these well-established drugs might be effective in preventing or treating COVID-19 but there is no conclusive proof.

Unveils details of how a widely used catalyst splits water
Unveils details of how a widely used catalyst splits water
A crystalline compound called ruthenium dioxide is widely used in industrial processes, where it's particularly important for catalyzing a chemical reaction that splits molecules of water and releases oxygen. But the exact mechanism that takes place on this material's surface, and how that reaction is affected by the orientation of the crystal surfaces, had never been determined in detail.

Enrichment Programs Help Children Build Knowledge
New research suggests enrichment programs help children solidify the information they have added to their wall of knowledge How humans organize information plays an integral role in memory, reasoning and the ability to acquire new knowledge. In the absence of routine education programs, the pandemic is exacerbating the disparities in educational opportunities available for children to develop new skills.

High doses of vitamin D supplementation has no benefit in preventing or treating COVID-19
Scientists from the UK, Europe and the USA, including experts from the University of Birmingham, have published a vitamin D consensus paper warning against high doses of vitamin D supplementation. According to the study, current research shows vitamin D has no benefit in preventing or treating Covid-19.

This COVID-19 Detector Has Berkeley Lab Roots
A technology spun from carbon nanotube sensors discovered 20 years ago by Lawrence Berkeley National Laboratory (Berkeley Lab) scientists could one day help health care providers test patients for COVID-19, the disease caused by the coronavirus SARS-CoV-2. When Alex Zettl , Marvin Cohen , and their research teams at Berkeley Lab first demonstrated ultrasensitive oxygen sensors devised from carbon nanotubes - hollow carbon wires with walls no thicker than an atom - they envisioned a broad spectrum of applications, such as gas-leak detectors or airand water-pollution detectors.

World can likely capture and store enough carbon dioxide to meet climate targets
The world is currently on track to fulfil scenarios on diverting atmospheric CO2 to underground reservoirs, according to a new study by Imperial. The capture and storage of carbon dioxide (CO2) underground is one of the key components of the Intergovernmental Panel on Climate Change 's (IPCC) reports keeping global warming to less than 2°C above pre-industrial levels by 2100.

Millions of people drink groundwater contaminated with arsenic
Millions of people drink groundwater contaminated with arsenic
Today, one third of the world's population obtains its drinking water and water for irrigation from groundwater reserves. Global population growth and water scarcity due to climate change mean that the pressure on this resource is continually increasing. However, many wells are contaminated with naturally occurring arsenic.
