Medical Xpress / Yawns in healthy fetuses might indicate mild distress
Even in the womb, where all oxygen is provided by the parental placenta, fetuses can—and do—yawn. More yawns during observation were associated with a lower weight at birth—potentially indicating mild fetal stress in ...
Medical Xpress / In Rett syndrome, leaky brain blood vessels traced to microRNA
MIT researchers have discovered that two common genetic mutations that cause Rett syndrome each set off a molecular chain of events that compromises the structural integrity of developing brain blood vessels, making them ...
Medical Xpress / Keto diet may restore exercise benefits in people with high blood sugar
To be healthy, conventional wisdom tells us to exercise and limit fatty foods. Exercise helps us lose weight and build muscle. It makes our hearts stronger and boosts how we take in and use oxygen for energy—one of the ...
Medical Xpress / Skeletal muscle retains a 'molecular memory' of repeated disuse, study finds
Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that skeletal muscle retains ...
Phys.org / Iron and blue LEDs synthesize natural molecules, cutting the need for expensive chiral components
Photocatalysts facilitate chemical reactions by absorbing light. Metal-based photocatalysts are widely used in organic synthesis due to their durability and the ability to tune their function by modifying the ligands attached ...
Phys.org / Viruses reveal shared way to kill bacteria by jamming small transporter MurJ
Biochemists at Caltech have identified how viruses have converged on a method for killing bacteria. The researchers have homed in on an underexplored small transporter called MurJ that is a vital part of the pathway bacteria ...
Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers
A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
Medical Xpress / 'Off the shelf' immunotherapy could get a lift from gene-edited natural killer cells
Since scientists first discovered that human immune cells could be modified to become cancer-fighting agents, they've been trying to engineer a cell that's effective against solid tumors, which account for the vast majority ...
Medical Xpress / Gallbladder cancer could soon be detected in blood
Researchers at Tezpur University in Assam, India, working with scientists at the University of Illinois Urbana-Champaign, have identified distinct chemical signatures in blood that could help detect gallbladder cancer earlier. ...
Medical Xpress / Black Americans face increasingly higher risk of gun homicide death than white Americans
Firearm homicide death rates have long been disproportionately higher for Black Americans compared to white Americans, and a new analysis across 45 years suggests that in recent years, this disparity has grown. Alex Knorre ...
Phys.org / Chemists thought phosphorus had shown all its cards—until it surprised them with a new move
A discovery by UCLA organic chemists may one day put catalytic converter thieves out of business. In new research, they've used abundant, inexpensive phosphorus as a catalyst in chemical reactions that usually require precious ...
Phys.org / Ant queen frozen in time: New ant species found in Dominican amber
A study by Dr. Gianpiero Fiorentino and his colleagues, published in the Journal of Paleontology, describes the identification of a new species of ant, Hypoponera electrocacica, belonging to the genus Hypoponera and representing ...
