Study points to increased risk of harm from cannabis across Europe
A significant new study shows that cannabis potency has doubled across Europe in the past 11 years.

Wireless 'pacemaker for the brain' could offer new treatment for neurological disorders
A new neurostimulator developed by engineers at the University of California, Berkeley, can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and Parkinson's.

The immune system's fountain of youth
Helping the immune system clear away old cells in aging mice helped restore youthful characteristics.

Canagliflozin not associated with increased risk for fracture
Compared with a glucagon-line peptide-1 (GLP-1) agonist, canagliflozin was not associated with an increased risk for fracture in patients with type 2 diabetes at relatively low risk for fracture.

Some tensions are good for life
In a recent study, Joseph Jose Thottacherry, along with his collaborators from other Indian and Spanish institutes, has tried to understand how cells maintain their shapes in spite of expelling material from their membrane.

Thriving on teamwork: new research shows how brain cells filter information in groups
For decades, scientists studying the visual system thought that individual brain cells, called neurons, operate as filters.

Researchers discover a metamaterial with inherently robust sound transport
Researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York and at the City College of New York (CCNY) have developed a metamaterial that can transport sound in unusually robust ways along its edges and localize it at its corners.

Unmuting large silent genes lets bacteria produce new molecules, potential drug candidates
By enticing away the repressors dampening unexpressed, silent genes in Streptomyces bacteria, researchers at the University of Illinois have unlocked several large gene clusters for new natural products.

Smelling in tiny houses: how ciliary electric currents keep olfaction reliable
Scientists have used a combination of mathematical modeling, electrophysiology, and computer simulations to explain how cells communicate effectively in highly constricted spaces such as the olfactory cilia, where odor detection takes place.

Physicists record 'lifetime' of graphene qubits
Researchers from MIT and elsewhere have recorded, for the first time, quantum coherence of a graphene-based superconducting qubit, meaning how long it stays in superposition to compute with two logical states simultaneously.

Don't go breaking my heart
For the first time, engineers have demonstrated an electronic device to closely monitor beating heart cells without affecting their behavior.

Patients now living a median 6.8 years after stage IV ALK+ lung cancer diagnosis
Stage IV ALK+ lung cancer patients treated at UCHealth University of Colorado Hospital between 2009 and 2017 had median overall survival of 6.8 years.

Tumors backfire on chemotherapy
Chemotherapy is an effective treatment for breast cancer, yet some patients develop metastasis in spite of it.

Scientists: 'Time is ripe' to use big data for planet-sized plant questions
A group of Florida Museum of Natural History scientists has issued a 'call to action' to use big data to tackle longstanding questions about plant diversity and evolution and forecast how plant life will fare on an increasingly human-dominated planet.

From a molecule of natural origin new therapeutic opportunities against hypertension
Spirulina is celebrated as a 'superfood' because of its possible beneficial properties, albeit its mechanism of action is still subjected to investigation.

A new 'atlas' of genetic influences on osteoporosis
A ground-breaking new study led by researchers from the Lady Davis Institute (LDI) at the Jewish General Hospital (JGH) has succeeded in compiling an atlas of genetic factors associated with estimated bone mineral density (BMD), one of the most clinically relevant factors in diagnosing osteoporosis.

Community-based HIV testing effective in reaching undiagnosed populations, new study finds
Results from a PATH-led evaluation study in Vietnam demonstrate that HIV testing by lay providers is an effective approach to reach people at risk of HIV who have never been tested or test infrequently.

NYUAD study suggests that 'Actin' is critical in genome regulation during nerve cell formation
One of the most fascinating questions in biology is how genes are regulated during development and differentiation when cells acquire a specific identity.

Scientists produce 'designer triacylglycerols' in industrial microalgae
A research team led by Prof. XU Jian from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), has discovered two novel diacylglyceryl transferases (DGAT2s) that preferentially attach LA and EPA, respectively, to the glycerol backbone to form TAGs.

Early protostar already has a warped disk
Using observations from the ALMA radio observatory in Chile, researchers have observed, for the first time, a warped disk around an infant protostar that formed just several tens of thousands of years ago.

Juno mission captures images of volcanic plumes on Jupiter's moon Io
The Juno spacecraft captured new images of a volcanic plume on Jupiter's moon Io during a December 21 flyby.

Natural-based antibiofilm and antimicrobial peptides from microorganisms
The exploration of AMP and antibiofilm peptide (ABP) producer microorganisms brings with it a lot of challenges experimentally.
