Researchers find how cells move while avoiding adhesion
Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise mechanisms of this relationship have remained elusive for decades. Now, researchers from the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) and Ludwig Maximilians Universität München (LMU) have figured out the precise mechanics and developed a...
Latch, load and release: Elastic motion makes click beetles click, study finds
Click beetles can propel themselves more than 20 body lengths into the air, and they do so without using their legs. While the jump's motion has been studied in depth, the physical mechanisms that enable the beetles' signature clicking maneuver have not. A new study examines the forces behind this super-fast energy release and provides guidelines for studying extreme motion, energy storage and...
Lasers and molecular tethers create perfectly patterned platforms for tissue engineering
Imagine going to a surgeon to have a diseased or injured organ switched out for a fully functional, laboratory-grown replacement. This remains science fiction and not reality because researchers today struggle to organize cells into the complex 3-D arrangements that our bodies can master on their own.
Call to prioritise minority ethnic groups for Covid vaccines
BAME communities should be better protected as they are more at risk, say public health experts and MPs People in high-risk minority ethnic groups must be prioritised for Covid immunisations, alongside a targeted publicity campaign, experts and politicians have said amid growing concerns over vaccine scepticism.With figures on Monday recording more than 4m Covid vaccine doses now administered...
Shetland space launch plans submitted
The proposals which have gone to the council and could support hundreds of jobs include three launch pads for rockets.
Almost 30% of Covid patients in England readmitted to hospital after discharge – study
Readmission rate for Covid patients 3.5 times greater, and death rate seven times higher, than for other hospital patients Coronavirus – latest updatesSee all our coronavirus coverageNearly a third of people who were discharged from hospitals in England after being treated for Covid-19 were readmitted within five months – and almost one in eight died, a study suggests.The research, which is...
Where COVID-19 hit hardest, sudden deaths outside the hospital increased, study finds

A study across New York City found that out-of-hospital sudden deaths follow the geographic distribution of SARS-CoV-2, suggesting an association between the two, investigators report.
A new archaeology for the Anthropocene era
- ScienceDaily
- 21/1/18 17:31
Scantily clad tomb raiders and cloistered scholars piecing together old pots -- these are the kinds of stereotypes of archaeology that dominate public perception. Yet archaeology in the new millennium is a world away from these images. In a major new report, researchers probe a thoroughly modern and scientific discipline to understand how it is helping to address the considerable challenges of the...
Climate change will alter the position of the Earth's tropical rain belt
- ScienceDaily
- 21/1/18 17:31
Researchers describe future changes to the tropical rain belt with expected climate change. The changes will cause droughts in large sections of the globe, threatening biodiversity and food security.
Inexpensive battery charges rapidly for electric vehicles, reduces range anxiety
- ScienceDaily
- 21/1/18 17:31
Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes.
A 'super-puff' planet like no other

- 21/1/18 17:31
Astronomers discover that the core mass of exoplanet WASP-107b is much lower than previously thought possible for a gas-giant planet.
Personalized brain stimulation alleviates severe depression symptoms
- ScienceDaily
- 21/1/18 17:31
Targeted neuromodulation tailored to individual patients' distinctive symptoms is an increasingly common way of correcting misfiring brain circuits in people with epilepsy or Parkinson's disease. Now, scientists have demonstrated a novel personalized neuromodulation approach that -- at least in one patient -- was able to provide relief from symptoms of severe treatment-resistant depression within...

Researchers have found new evidence about the positive role of androgens in breast cancer treatment with immediate implications for women with estrogen receptor-driven metastatic disease.
Low-carbon policies can be 'balanced' to benefit small firms and average households
- ScienceDaily
- 21/1/18 17:31
A review of ten types of policy used to reduce carbon suggests that some costs fall on those less able to bear them - but it also shows these policies can form the bedrock of a 'green recovery' if specifically designed and used in tandem.
Synthesis of potent antibiotic follows unusual chemical pathway
- ScienceDaily
- 21/1/18 17:31
Images of a protein involved in creating a potent antibiotic reveal the unusual first steps of the antibiotic's synthesis. The improved understanding of the chemistry behind this process could allow researchers to adapt this and similar compounds for use in human medicine.
New computational tool reliably differentiates between cancer and normal cells from single-cell RNA-sequencing data

Researchers have developed a new computational tool to accurately differentiate between cancer cells and normal cells when analyzing large single-cell RNA-sequencing data.
Zebra stripes, leopard spots and other patterns on the skin of frozen metal alloys that defy conventional metallurgy
While it is fascinating that living creatures develop distinct patterns on their skin, what may be even more mysterious is their striking similarity to the skin of frozen liquid metals.
New management approach can help avoid species vulnerability or extinction
More than 3,000 animal species in the world today are considered endangered, with hundreds more categorized as vulnerable. Currently, ecologists don't have reliable tools to predict when a species may become at risk.
Researchers: Climate change will alter the position of the Earth's tropical rain belt
Future climate change will cause a regionally uneven shifting of the tropical rain belt—a narrow band of heavy precipitation near the equator—according to researchers at the University of California, Irvine and other institutions. This development may threaten food security for billions of people.
Synthesis of potent antibiotic follows unusual chemical pathway
Images of a protein involved in creating a potent antibiotic reveal the unusual first steps of the antibiotic's synthesis. The improved understanding of the chemistry behind this process, detailed in a new study led by Penn State chemists, could allow researchers to adapt this and similar compounds for use in human medicine.
A 'super-puff' planet like no other
The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found.
A new archaeology for the Anthropocene era
Indiana Jones and Lara Croft have a lot to answer for. Public perceptions of archaeology are often thoroughly outdated, and these characterisations do little to help. Archaeology as practiced today bears virtually no resemblance to the tomb raiding portrayed in movies and video games. Indeed, it bears little resemblance to even more scholarly depictions of the discipline in the entertainment...
