Antibiotic discovery is always welcome. Here's a new one from a well-searched area ( Actinomycetes extracts), and the authors (university teams from McMaster, Indiana, and Montreal) did a lot of groundwork to make sure that they weren't just going to rediscover known agents. That's a serious problem with broad-based antibiotic screening, as you'd imagine, and there are several ways to try to get
A team of scientists led by Elizabeth Boatman at the University of Wisconsin Stout used infrared and X-ray imaging and spectromicroscopy performed at Berkeley Lab's Advanced Light Source (ALS) to demonstrate how soft tissue structures may be preserved in dinosaur bones—countering the long-standing scientific dogma that protein-based body parts cannot survive more than 1 million years.
Crotoxin, extracted from the venom of the South American rattlesnake Crotalus durissus terrificus, has been studied for almost a century for its analgesic, anti-inflammatory and antitumor activities and as an even more powerful muscle paralyzer than botulinum toxin. However, the toxicity of crotoxin limits its medicinal use.
Engineers at the University of Queensland say technology could be used to power small devices, such as a phone, within two years A flexible solar "skin" that could be used to generate power on homes, cars and phones is a step closer to development after the technology was used to break a world record for electricity conversion, researchers say. Engineers at the University of Queensland have been
People who rely on social media for information were more likely to be misinformed about vaccines than those who rely on traditional media, according to a study by the Annenberg Public Policy Center. The study, based on surveys of nearly 2,500 US adults, found that up to 20% of respondents were at least somewhat misinformed about vaccines.

The climate change crisis has resulted in an emphasis on the role of broad-scale climate in controlling species distributions. A key metric for predicting the impacts of climate change on species and ecosystems is the local velocity of climate change: how fast a species must move across the landscape to track its preferred climate in space. However, other ecologically important environmental varia

Why do predators sometimes lay dormant eggs, which are hardy, but take a long time to hatch and are expensive to produce? That is the question that researchers from Singapore University of Technology and Design (SUTD) set out to answer in a recent paper published in Advanced Science.
A sweet ride if you can get there. Advanced civilizations could sail away on black hole jets at the center of some galaxies. (Lynette Cook/) Greta Thunberg's transatlantic voyage showed the world that inter-continental travel doesn't have to rely on fossil fuels . By harnessing the freely available energy blowing in the wind, the 16-year-old Swede managed to sail around 3,500 miles from the UK to
The federal flood buyout program disproportionally benefits at-risk homes in the whitest communities of America's largest cities, a new study shows. Researchers examined data in 500 municipalities across the US between 1990 and 2015 to come up with the first nationwide, peer-reviewed analysis of racial inequalities in the implementation of the Federal Emergency Management Agency's (FEMA) flood bu
There are 350,000 chemicals available on the market and in circulation worldwide, according to a new estimate. The last time researchers compiled a list, it only ran to 100,000 entries. Drawn up shortly after the turn of the millennium, the list focused on markets in the US, Canada, and western Europe. That made sense at the time because 20 years ago, these countries accounted for more than two t
Homeschooled adolescents may have significantly lower abdominal strength and endurance than public school students who are required to take part in physical education programs, according to a new study. This was despite no significant difference between the two groups in measurements of body mass index, the researchers found. The study compares specific health metrics between two sets of students
Every day millions of people rely on central nervous system stimulants to boost focus and energy. Unfortunately, these stimulants often come with a wide variety of unpleasant side effects, and in the case of some, prolonged use can result in serious long term damage to your brain. Luckily, a company called Recoop has created a pair of dietary supplements specifically engineered to counteract the
Even a few hours of exposure to ambient ultrafine particles common in air pollution may potentially trigger nonfatal heart attacks, research suggests. Myocardial infarction is a major form of cardiovascular disease worldwide. Ultrafine particles (UFP) are 100 nanometers or smaller in size. In urban areas, automobile emissions are the primary source of UFP. The study in the journal Environmental H
The UK government has denied a freedom of information request to explain why it estimates the cost of hitting net-zero emissions by 2050 is £70 billion a year – much higher than an independent assessment found
Redan för fyra tusen år sedan producerades ylletextilier storskaligt i Mellanöstern och bort mot östra Medelhavet. Snabbt spred sig hantverket i Europa och handeln med ull, garn och textilier blev väldigt viktig, lika viktig som handeln med bronsens beståndsdelar koppar och tenn. – Med bronsen kom också ullen till våra breddgrader. Vi ser det i danska gravar med ekkistor som bevarat organiskt mate
A US jury has awarded $265 million to a Missouri farmer who blamed herbicide from chemical giants Bayer AG and German rival BASF for destroying his peach orchards, in a case set to bolster 140 other lawsuits.
Major industrialized nations currently live in a "consume and dispose" world. This is great for firms' bottom lines and abstract measures such as GDP, but the social and environmental costs of this way of life have been high—for example, the high price of "fast fashion". We're all encouraged to use less and recycle more, but how can we as a society shift to a "consume and pass on" model?
Utanför de olika intagningsrummen på barnonkologen avdelning 64, hänger inplastade namnskyltar med regnbågar, enhörningar och traktorer som de unga patienterna själva har gjort. Hit kommer varje år runt 60 nyinsjuknade barn i cancer från södra Sverige. Av dem överlever 85 procent. Här har även barnläkaren och forskaren Kees-Jan Pronk en av sina två arbetsplatser.
"[T]he single healthiest thing most of us can do for our relationship with politics and for politics would be to deemphasize our connection to national politics and reemphasize our connection to state and local politics," says Ezra Klein. The media has become overwhelmingly nationalized. To improve your relationship with politics, and to improve politics in general, be intentional about your info
An NTSB drone perspective of the flight path and subsequent accident impact site. (NTSB/) The National Transportation Safety Board on Friday published a number of details the board has gathered from ADS-B tracking data, ground-based video camera footage and witnesses since the January 26 crash of a Sikorsky S76, N72EX, in the hilly terrain near Calabasas, California. The flight, operated under Pa
The Dauberts joined an elite group of plaintiffs whose names have become ubiquitous in the legal system. But in the sweep of history, the lives of a family whose personal tragedy gave rise to the practice of vetting scientific experts in the courtroom had largely been scrubbed from the record.
Elon Musk and Jeff Bezos have become mildly obsessed with building colonies on Mars. SpaceX has released glossy depictions of a Martian City home to 1 million people. There's also talk about terraforming Mars to make it habitable for humans. My response to this is a simple "what's the point?". Even if Mars had a breathable atmosphere and some sort of artificial magnetosphere (highly speculative t
David Robson thinks the time it will take to make contact presents a problem. John Boyd questions the purpose of finding extraterrestrial life when we can't respect life on our own planet While reading your report ( Is anybody out there? Biggest hunt ever to begin for alien life , 15 February) I wondered why scientists are trying to persuade people to believe there is any point in contacting life
Scientists have created one of the most detailed maps of breast cancer ever achieved, revealing how genetic changes shape the physical tumour landscape, according to research funded by Cancer Research UK and published in Nature Cancer today (Monday). An international team of scientists has developed intricate maps of breast tumour samples, with a resolution smaller than a single cell.
