Researchers found that bacteria in the gut, rather than liver enzymes, are crucial for allowing herbivores to feed on toxic plants. Fecal transplants with microbes from creosote-eaters enabled woodrats to eat toxic creosote bushes, confirming their importance in adapting to new diets.
Astronomers discover that small galaxies orbit in orderly disc-shaped orbits, contradicting computer models. The phenomenon is observed in about 50% of galaxies, sparking a reevaluation of dark matter's nature and the laws of physics.
A multi-disciplinary team of scientists has discovered that a gene called MED12 is altered in nearly 60% of fibroadenomas, the most common benign breast tumours diagnosed in women. The study's findings have potential applications in distinguishing fibroadenomas from breast cancer and developing targeted therapies.
The study reveals genetic changes associated with twinning in marmosets, including the WFIKKN1 gene that may act as a critical switch between multiples and singleton pregnancies. Marmosets also exhibit unique social behavior, where relatives care for offspring while reproductively suppressed.
Researchers at the University of Liverpool have successfully extracted atoms of rare or dangerous elements such as radon from the air using a material called CC3. This new method has potential applications in industries like lighting, medicine, and nuclear waste clean-up.
Researchers at University of East Anglia have developed a new model that takes into account the impact of oceans on climate, finding they play a vital role in moderating temperatures and habitability. This breakthrough helps answer whether other planets could sustain alien life.
Researchers developed a powerful single-cell technique to study environmental effects on DNA, mapping epigenetic marks in individual cells. This approach has the potential to enhance clinical applications like cancer therapy and fertility treatments.
A recent report from the University of Plymouth reveals an increase in public complaints against doctors in the UK. Clinical care remains a leading cause, while doctor-patient communication has also seen a significant rise.
Researchers at UC Berkeley developed a tiny laser sensor that can detect minute concentrations of explosives, including pentaerythritol tetranitrate, an explosive favored by terrorists. The device has the potential to replace traditional bomb-screening methods and could also be used to detect unexploded land mines.
Researchers reveal detailed images of anaphase-promoting complex (APC/C), a protein that controls mitosis. The discovery could lead to new cancer drugs by identifying binding sites for future treatments.
A study found that offering food vouchers worth $9 or $15 resulted in a modest increase in circumcision rates among uncircumcised men in Kenya. The interventions also increased circumcision uptake among married and older participants, as well as those at higher risk of HIV acquisition.
Researchers at Howard Hughes Medical Institute's Janelia Research Campus have created a computational method to rapidly track cell movements in data-rich images. This enables the automation of reconstructing an animal's developmental building plan cell by cell, with potential applications in understanding how the nervous system forms.
A new study found that turbulent mixing in the deep waters of the Southern Ocean varies with surface eddy strength and possibly wind speeds, impacting global ocean circulation and climate. This insight will enable scientists to build better computer models predicting future climate change.
Researchers funded by NIH found that common gene variants account for most genetic risk for autism, outweighing other factors. The study used a large Swedish sample and new statistical methods to detect common genetic variation associated with risk.
A new porous material called CC3 effectively traps radioactive krypton and xenon gases from nuclear fuel, using less energy than conventional methods. The material's selectivity is higher than other experimental materials, making it a promising solution for removing unwanted elements.
Using new statistical tools, researchers found that about 52% of autism cases are linked to common genes, while spontaneous mutations account for only 2.6%. Inheritability outweighs environmental risk in the disorder.
A recent study led by researchers at the Icahn School of Medicine at Mount Sinai found that nearly 60% of autism risk is caused by inherited variant genes common in the population. Rare genetic factors, such as de novo mutations, also contribute to the disorder, but only account for a small fraction of total risk.
A study by the University of Pennsylvania School of Medicine identified an enzyme called FBP1 that regulates metabolism and restrains energy production in cells. The enzyme is missing from all kidney tumor tissue, leading to rapid cell growth. This discovery may lead to personalized approaches for treating clear cell renal cell carcino...
A new study by University of Arizona researchers found that plant size and age control most of the variation in plant productivity, not temperature and precipitation as traditionally thought. Climate still plays an important role, but its influence on ecosystem functioning has been revised.
A new study led by Old Dominion University and the University of Colorado Boulder found sea levels are rising in the tropical Pacific off the coasts of the Philippines and northeastern Australia. The research team estimated that areas near these regions are being raised by about 1 centimeter per year due to anthropogenic warming.
Scientists have discovered that the HIV viral reservoir is established remarkably early after infection, posing new challenges for its eradication. The study found that the reservoir was seeded in tissues within days of infection, before detectable virus was present in the blood.
