Intermittent fasting maintains long-term weight loss, regardless of meal timing, study sho
A team of scientists from the University of Granada (UGR), the Granada Institute for Biomedical Research (ibs.GRANADA), the Public University of Navarra and the Biomedical Research Networking Center (CIBER) has demonstrated that limiting food intake to an eight-hour window helps
New tumor map identifies high-risk B-cell lymphoma standard therapy may miss
Researchers led by Universitätsmedizin Frankfurt and Goethe University Frankfurt have identified how particularly aggressive forms of lymphoma can be recognized. By combining genetic and proteomic analyses, the scientists identified biological characteristics of tumors, particula

New virus catalog reveals which pathogens pose the greatest threat
In a typical year, scientists discover two or three viruses that have never been seen in people before. The number fluctuates, but the trend has been fairly steady since the 1960s.
HIV vaccine triggers broadly neutralizing antibodies in 44% of primates
A new HIV vaccine developed by La Jolla Institute for Immunology (LJI), Scripps Research scientists and IAVI has the potential to protect humans from developing HIV infection and AIDS. This HIV vaccine is the first to generate a high number of "broadly neutralizing" virus-fightin
Scientists uncover two neuronal circuits orchestrating muscle autophagy
Scientists uncover two neuronal circuits orchestrating muscle autophagy
Autophagy is the process by which cells remove damaged proteins, recycle worn-out organelles (e.g., mitochondria), clear cellular waste and provide nutrients during stress. Autophagy is essential for muscles because they are constantly under mechanical stress. If autophagy is too
Hormone differences could pave way for endometriosis blood test
People with endometriosis have a distinct pattern of hormones that could be identified by a blood test, with the potential to revolutionize diagnosis of the condition, research suggests. Scientists have found that those with endometriosis have differences in a previously overlook
Tumor on a chip reveals how pancreatic cancer hijacks immune cells in real time
A new "tumor-on-a-chip" model is giving scientists a live look at how pancreatic cancer can recruit the body's own immune cells to help tumors survive. Researchers say the findings, published in Biofabrication, reveal possible new targets to weaken the cancer's defenses and make

Astrocytes help preserve memories for weeks by stabilizing neural circuits
Some memories remain with us for years, shaping how we learn from experience and adapt to the world around us. Others disappear quickly, even when they once seemed important. Although scientists have long studied how memories are formed in the brain, far less is known about what
Promising medication combination to treat an 'undruggable' type of lung cancer
Breakthrough research led by scientists in Manchester has identified a new drug combination that could improve outcomes for thousands of patients with lung cancer driven by a rare type of KRAS mutation, offering hope for patients worldwide with this difficult-to-treat subtype of
Study linking microgravity and space radiation to accelerated aging could yield therapies
Study linking microgravity and space radiation to accelerated aging could yield therapies
What happens to the human body in space may help scientists create new anti-aging therapies. UCF's Michal Masternak and his team have identified molecular changes in the liver that happen when space travelers experience radiation and microgravity. These changes—that resemble acce
What do Sardinia's Blue Zone elders do differently that helps them age so well physically
What do Sardinia's Blue Zone elders do differently that helps them age so well physically
People are living longer than they did at the turn of the 20th century, but living well into old age depends on more than a healthy lifestyle. Scientists say it is also shaped by how we think, adapt and connect with others.
Gut bacteria boost immune system, help send vitamin A to T cells
Scientists at UT Southwestern Medical Center have discovered that gut bacteria help regulate the development of the body's immune system by directing the movement of vitamin A through a previously unrecognized cellular network. The preclinical findings, published in Cell Host & M
