Hematopoietic stem cell transplants may provide long-term benefit for people with MS
- ScienceDaily
- 21/1/20 22:20
A new study shows that intense immunosuppression followed by a hematopoietic stem cell transplant may prevent disability associated with multiple sclerosis (MS) from getting worse in 71% of people with relapsing-remitting MS for up to 10 years after the treatment. The study also found that in some people their disability improved over 10 years after treatment.

Late rainy season reliably predicts drought in regions prone to food insecurity
- ScienceDaily
- 21/1/20 21:10
The onset date of the yearly rainy season reliably predicts if seasonal drought will occur in parts of Sub-Saharan Africa that are particularly vulnerable to food insecurity, and could help to mitigate its effects.
On the origins of money: Ancient European hoards full of standardized bronze objects

In the Early Bronze Age of Europe, ancient people used bronze objects as an early form of money, even going so far as to standardize the shape and weight of their currency, according to a new study.
Designer DNA therapeutic wipes out cancer stem cells, treats multiple myeloma in mice
- ScienceDaily
- 21/1/20 18:24
A new study supports launch of Phase I clinical trial to test a designer DNA agent -- an antisense oligonucleotide that targets a gene called IRF4 -- in patients with multiple myeloma.
New metamaterial offers reprogrammable properties
- ScienceDaily
- 21/1/20 17:48
Scientists have developed a metamaterial whose mechanical properties can be reprogrammed on demand and whose internal structure can be modified by applying a magnetic field.
Immune driver of brain aging identified
- ScienceDaily
- 21/1/20 17:48
Stanford scientists have identified a key factor in mental aging and shown that it might be prevented or reversed by fixing a glitch in the immune system's frontline soldiers.
Methamphetamine overdose deaths rise sharply nationwide
- ScienceDaily
- 21/1/20 17:48
Methamphetamine overdose deaths surged in an eight-year period in the United States, according to a new study. The analysis revealed rapid rises across all racial and ethnic groups, but American Indians and Alaska Natives had the highest death rates overall.
Age influences sex-related outcomes after heart attack
- ScienceDaily
- 21/1/20 14:51
Approximately 1.5 million heart attacks and strokes occur every year in men and women in the US. Sex and age play a large part in who experiences a heart attack, the methods used to treat these heart attacks, and the eventual post hospital outcomes of the people who experience heart attacks.
New antifungal compound from ant farms
- ScienceDaily
- 21/1/20 14:50
Attine ants are farmers, and they grow fungus as food. Pseudonocardia and Streptomyces bacteria are their farmhands, producing metabolites that protect the crop from pathogens. Surprisingly, these metabolites lack common structural features across bacteria from different geographic locations, even though the ants share a common ancestor. Now, researchers report they have identified the first...
An anode-free zinc battery that could someday store renewable energy
- ScienceDaily
- 21/1/20 14:50
Renewable energy sources, such as wind and solar power, could help decrease the world's reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers have made a prototype of an anode-free, zinc-based battery...
Study shows how network of marine protected areas could help safeguard Antarctic penguins
- ScienceDaily
- 21/1/20 14:50
New research highlights how a proposed network of marine protected areas could help safeguard some of the most important areas at sea for breeding Antarctic penguins.
Breakthrough in understanding 'tummy bug' bacteria
- ScienceDaily
- 21/1/20 14:50
Scientists have discovered how bacteria commonly responsible for seafood-related stomach upsets can go dormant and then 'wake up'.
Making microwaves safer for children

- 21/1/20 14:50
Researchers worked diligently to document the frequency and severity of burn injuries resulting from removing hot contents from the microwave and young children's vulnerability to them.
Free online tool calculates risk of COVID-19 transmission in poorly-ventilated spaces
- ScienceDaily
- 21/1/20 01:44
The vital role of ventilation in the spread of COVID-19 has been quantified by researchers, who have found that in poorly ventilated spaces, the virus spreads further than two meters in seconds, and is far more likely to spread through prolonged talking than through coughing.
Amber-encased fossil shines light on evolution of bioluminescent insects
- ScienceDaily
- 21/1/20 01:44
Trapped in amber for ~100 million years, an exceptionally well-preserved, light-producing beetle sheds light on the diversification of bioluminescent beetles in the Cretaceous period and provides the missing fossil link between fireflies' living relatives.
Brain cell network supplies neurons with energy
- ScienceDaily
- 21/1/20 01:43
Until recently, oligodendrocytes were primarily thought to be a kind of cellular insulating tape that accelerates the transmission of electrical signals in the brain. A study now shows that they are also important for the energy supply of neurons in some brain regions.
Light-controlled Higgs modes found in superconductors; potential sensor, computing uses
- ScienceDaily
- 21/1/20 01:43
Researchers have discovered a short-lived form of the famous Higgs boson -- subject of a groundbreaking search at the Large Hadron Collider -- within an iron-based superconductor. This Higgs mode can be accessed and controlled by laser light flashing on the superconductor at trillions of pulses per second.
Fastener with microscopic mushroom design holds promise

A fastener with a microscopic design that looks like tiny mushrooms could mean advances for everyday consumers and scientific fields. Currently available fasteners are called hook and loop fasteners and require harder, stiff material. In Biointerphases, researchers describe a design that can use softer materials and still be strong. The team believes a 3D mushroom design can be made with softer,...
