NUS researchers develop new battery-free technology to power electronic devices using ambient radiofrequency signals
National University of Singapore (NUS)

Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module – developed by a team led by scientists from the National University of Singapore (NUS) – can now convert ambient or ‘waste’ RF signals into direct current (DC) voltage.

High Levels of a Specific Antibody May Contribute to Acute Coronary Syndrome

How a person’s immune system responds to a protein called LL-37 may increase risk for developing acute coronary syndrome, but the response may also serve as a potential target for future treatments.

Sipping Alcohol in Early Adolescence May Contribute to Personality Changes and Depression
Research Society on Alcoholism

Children who try alcohol may experience mental health and personality effects as they transition to early adolescence. An analysis of alcohol sampling behavior in children ages 9 to 14, published in Alcohol: Clinical and Experimental Research, found that children who had poor response inhibition and increased alcohol sipping behaviors might be more likely to have accelerated changes in personality traits and depression scores over time. The study suggests that even minimal alcohol experimentation in early adolescence may influence later alcohol use as well as personality and mental health issues.

New research discovers a new combination of therapy for people with a type of leukemia, leading them to live longer
Mayo Clinic

In a new multicenter international study led by the Mayo Clinic Comprehensive Cancer Center, researchers found that people with the B-cell precursor subtype of acute lymphoblastic leukemia (BCP-ALL), who also lacked a genetic abnormality known as the Philadelphia chromosome and were in remission with no trace of cancer, showed significantly higher survival rates when blinatumomab was added to their chemotherapy treatment.

Does Your Body Composition Affect Your Risk of Dementia or Parkinson’s?
American Academy of Neurology (AAN)

People with high levels of body fat stored in their belly or arms may be more likely to develop diseases like Alzheimer’s and Parkinson’s than people with low levels of fat in these areas, according to a study published in the July 24, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Nationwide flood models poorly capture risks to households and properties
University of California, Irvine

Irvine, Calif., July 24, 2024 – Government agencies, insurance companies and disaster planners rely on national flood risk models from the private sector that aren’t reliable at smaller levels such as neighborhoods and individual properties, according to researchers at the University of California, Irvine. In a paper published recently in the American Geophysical Union journal Earth’s Future, experts in UC Irvine’s Department of Civil and Environmental Engineering caution that relatively new, nation-scale flood data provides an inadequate representation of local topography and infrastructure, factors known to control the spread of floods in urban areas.

حدد علماء مايو كلينك نوع جديد من فقدان الذاكرة لدى البالغين الأكبر سنًا
Mayo Clinic

روتشستر، ولاية مينيسوتا — وضع الباحثون في مايو كلينك معايير جديدة لمتلازمة فقدان الذاكرة لدى البالغين الأكبر سنًا والتي تؤثر تحديدًا على الجهاز الحوفي الدماغي، وقد يتم تشخيص هذه الحالة على سبيل الخطأ على أنها داء الزهايمر في كثير من الأحيان. الخبر السار هو أن متلازمة التنكس العصبي لفقد الذاكرة السائدة الحوفي تتفاقم بصورة أبطأ ولها تنبؤات أفضل بخصوص سَيْر المرض، كما أصبحت محددة بشكل أوضح للأطباء الذين يعملون على إيجاد إجابات لمرضى فقدان الذاكرة.

Researchers discover faster, more energy-efficient way to manufacture an industrially important chemical
Argonne National Laboratory

The reactivity of zirconium on silicon nitride enhances the conversion of propane into propylene, a key commodity chemical needed to make polypropylene. This finding hints at the reactivity researchers might achieve with other nontraditional catalysts.
