Public private partnerships have a better track record in promoting equity than many assume, researchers at the University of Maryland's (UMD) A. James Clark School of Engineering have found.
Experimental facilities around the globe are facing a challenge: their instruments are becoming increasingly powerful, leading to a steady increase in the volume and complexity of the scientific data they collect. At the same time, these tools demand new, advanced algorithms to take advantage of these capabilities and enable ever-more intricate scientific questions to be asked—and answered. For...
In the popular view of traditional science, scientists are in the lab hovering over their experiments, micromanaging every little detail. For example, they may iteratively test a wide variety of material compositions, synthesis and processing protocols, and environmental conditions to see how these parameters influence material properties. In each iteration, they analyze the collected data,...
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years, a new study from Oregon State University has found.

Sunlight in, reflected and emitted energy out. That's the fundamental energy balance sheet for our planet. If Earth's clouds, oceans, ice caps and land surfaces send as much energy back up to space as the sun shines down on us, then our planet maintains equilibrium.

Using advanced imaging technology, scientists have provided an unprecedented understanding of the BRCA1-BARD1 protein complex, which is often mutated in patients with breast or ovarian cancer. Their paper identifies aspects of how BRCA1-BARD1 functions, supporting future translational research, cancer prevention efforts and drug development.
Israeli government officials visited the offices of the hacking company NSO Group on Wednesday to investigate allegations that the firm’s spyware has been used to target activists, politicians, business executives, and journalists, the country’s defense ministry said in a statement today. An investigation published last week by 17 global media organizations claims that phone numbers…
Sunlight in, reflected and emitted energy out. That's the fundamental energy balance sheet for our planet -- and for decades, it has been out of balance. The extra energy manifests as higher temperatures, rising sea levels, floods, droughts, more powerful blizzards and hurricanes, and deadlier extreme events. Not only is the imbalance growing, but there's a 99% chance that the growth is due to...
In an attempt to find out why the long-term outcomes are poorer for patients with lobular breast cancer -- which affects some 40,000 women a year -- researchers began looking at the role of the protein MDC1 in tumor cells.
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years.

UK scientist says gene-drive study rendering female insects infertile may lead to ‘self destruct mosquito’ field tests within 10 yearsScientists have successfully wiped out a population of malaria-transmitting mosquitoes by using a radical form of genetic engineering to render the females infertile – in the most advanced and largest ever test of use of the technology to fight the disease.As...
Telescope picks up unexpected ‘luminous echoes’ – smaller, later and of different colour to bright flaresAstronomers have detected light behind a black hole deep in space for the first time.Bright flares of X-rays were spotted bursting from a supermassive black hole at the centre of a galaxy 800m light years away, which is relatively normal. Continue...
New research from the University of Florida explains how a family of bacteria called Yersinia infects the body so successfully.
A new study from CU Boulder finds that hundreds of millions of years ago, small single-celled organisms may have evolved into larger multicellular life forms to better propel themselves through icy waters.
MicroCT of infected human lung tissue, along with histology and immunohistochemistry, was used to construct images of TB granulomas, airways and vasculature.
With the Olympics underway, higher testosterone has often been linked to sporting success, and other kinds of success too. But beyond sport, new research has found little evidence that testosterone meaningfully influences life chances for men or women. In fact, the study suggests that despite the social myths surrounding testosterone, it could be much less important than previously thought.
The blood groups of three Neanderthals one Denisovan have been determined by a team including a palaeoanthropologist, population geneticists, and haematologists. Their research provides new data for understanding the origins, history, and health of these extinct hominin lineages.
An analysis of the blood types of one Denisovan and three Neanderthal individuals has uncovered new clues to the evolutionary history, health, and vulnerabilities of their populations. Silvana Condemi of the Centre National de la Research Scientifique (CNRS) and colleagues at Aix-Marseille University, France, present hese findings in the open-access journal PLOS ONE on July 28, 2021.

Pioneering biologist and geneticist whose research showed the emptiness of traditional biological concepts of raceThe American scientist Richard Lewontin, who has died aged 92, was intimately involved in some of the most important discoveries, and feuds, of evolutionary biology during the decades in which it passed from knowing that genes existed to specifying them in precise molecular terms.His...

New research identifies climate change challenges faced by U.S. Department of Defense facilities, and solutions that might serve as a model for other large organizations.
Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used a completely different approach to produce metallic water and documented the phase transition at BESSY II.
As the fertilized egg divides, initially undifferentiated cells take on specific functions, becoming more distinct as different tissues and organs emerge. Understanding how hundreds of disparate cell types arise has proven difficult, largely because scientists have lacked the technologies to capture cellular decision making over time.
Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used a completely different approach to produce metallic water and documented the phase transition at BESSY II. The study is published now in Nature.

Messenger RNA, or mRNA, has been in the news recently as a crucial component of the Pfizer-BioNTech and Moderna COVID-19 vaccines. The nucleic acid looks, for all intents and purposes, like a strand of DNA that has been sliced the long way. It's what's known as single-stranded RNA (ssRNA), and it can be found throughout the natural world.
Mitofusin 2 is a key protein in the regulation of the physiology of mitochondria—cellular organelles that produce energy—involved in several neurodegenerative and cardiovascular diseases, as well as in cancer. Now, a study published in the journal EMBO Reports reveals that the regulation of the bioenergetic activity in the mitochondria requires mitofusin 2 to be found in the endoplasmic...
